45,294 Nov. 29, 1864 Milling Machine Joseph R. Brown Providence, Providence County, RI From Studies in the History of Machine Tools by Robert S. Woodbury.

"At the time the involute method of determining gear-tooth shapes had been shown (by mathematicians) to be superior to the epicycloidal method, but practice lagged far behind as practical men stuck to the traditional epicycloidal approach. The first version of that Brown & Sharpe gear-cutting machine, introduced in 1864 or 1865, had available sets of 24 cutters for epicycloidal gears, sufficient to cut all gears of a given pitch, from a 12-tooth pinion gear to a rack. In 1867 they introduced cutter sets for involute gear teeth, each set requiring significantly fewer cutters than the equivalent epicycloidal set, and was therefore less expensive. As the only maker, at the time, of gear-cutting machines, Brown & Sharpe's introduction of involute cutters was vital to the move away from epicycloidal gear designs."

51,257 Nov. 28, 1865 Screw Cutting Machine Joseph R. Brown Providence, Providence County, RI Abstract:
My said improvement relates, first, to the means by which the rod or piece of metal from which the screw is to be formed is griped and held at the end of a revolving spindle; and it consists in combining with suitable griping jaws a set of wedges at the end of a rod or tube within the spindle, and a rotating screw for imparting a sliding movement longitudinally to the said rod or tube and the wedges thereon, so that the wedges are made to force the griping-jaws together to gripe the rod or piece of metal, and afterward to liberate the same while the spindle is revolving.

My improvement relates, secondly, to the means employed to4 hold and control the operation of the threading-tool; and it consists in combining a tool-holder capable of holding a tap or die or other suitable threading-tool with a reversible clutch in such a manner that the holder and tool may slide and cut the screw-thread up to a given point, and then be liberated by the clutch and revolve with the threaded-screw until the revolution of the spindle is reversed, when the tool-holder is arrested and held from turning while the tool is being withdrawn from the threaded screw.

Claims:
The combination of a set of griping-jaws, l, and a set of wedges on a sliding rod or tube, m, or its equivalent, with a hollow screw, F, the same being constructed and arranged to operate within a revolving spindle, substantially as described, for the purpose specified.

2. The combination of the threading-tool holder and the reversible clutch, constructed and arranged to co-operate with a revolving spindle.

Figure I is a top view of the improved grinding-machine. (The two broken lines indicate the position of the center-line of the table to which the head and foot stocks are secured when the table is swung on either the central or the end pin.) Pig. 2 is a front elevation of the machine. Pig. 3 is an enlarged sectional view through the center of the grinding-machine, the base being shown as broken off. Fig. 4 is a plan view of the laterally-swinging base-plate, on which the wheel-arbor is supported, in different positions. The object of this invention is to so construct a grinding-machine that the same shall be adapted to do a great variety of work a machine on which straight, tapering, curved, and irregular work, either inside or outside, can be ground with great accuracy. The nature of the invention consists in the arrangement of the parts, by which the relative positions of the table, the head and foot stocks, and the wheel-arbor, can be adjusted to adapt the same to a great variety of work and under all the changes control the adjustment with the greatest nicety.

202,866 Apr. 23, 1878 Micrometer Gage George M. Pratt Middletown, Middlesex County, CT This invention relates to that class of micrometer gages having horseshoe shaped frames, in which the object to be measured is clamped between a suitable abutment and the tip of a micrometer-screw. In order that the measurement by such an instrument shall be absolutely correct, it is necessary that the surfaces of said abutment and screw shall be perfectly smooth, and they should, therefore, be made as hard as possible, to resist abrasion and wear. In hardening these surfaces, the ordinary methods of tempering have been employed, the screw being completely formed and adjusted while the metal of which it was composed was soft, and afterward tempered. In thus tempering the screw after its complete formation, it has been found that its adjustment is always more or less impaired, as the heat necessary in the process of tempering expands the metal, a portion of the expansion being permanent, and the contraction, on cooling, unequal so that, though a micrometer-screw should be perfectly accurate before being tempered, it would often, after tempering, be found so altered as to materially affect its accuracy in the minute measurements for which such instruments are employed, and is then worthless for its intended purpose. Besides, when the screw is first perfectly accurate, if its tip becomes much worn, a new adjustment or the substitution of a new screw is necessary in either event involving more or less expense. The bar forming the horseshoe or U shaped frame of such an instrument has heretofore been formed of uniform width and thickness throughout its length; and, in order to give it sufficient rigidity to prevent springing, this frame has been of inconvenient weight and bulk. To obviate the necessity for heating the screws for tempering, to provide for their easy repair, thus reducing the expense, while preserving the accuracy of micrometer-gages, and also to render the frame of such an instrument strong, light, and of elegant shape, is the object of my invention; and it consists, first, in a micrometer-gage screw, having a socket formed in its end, and provided with a separate tip of tempered steel or similar hard material, whereby the necessity for heating the screw, in order to temper the tip, is obviated, and said screw is rendered easy to repair by the simple replacement of a worn tip by a new one, properly hardened and adjusted; second, in forming a micrometer-gage frame of an approximately crescent shape, or semicircular and tapering from its middle portion to its ends, in which the screw-bearings are located.

241,879 May. 24, 1881 Gear Wheel Cutter Edwin L. Parsons Providence, Providence County, RI Abstract:
The object of my invention is to set the cutter in the gear-cutting machine central with the spindle upon which the blank is held; and it consists in making a small line about two one-thousandths of an inch in width, (0.002,) more or less, in the center of the peripherical contour of one or more teeth of the cutter, transverse with its axis; or a conical or some other form of groove or mark may be used instead of a small line. Heretofore the eye has been the principal guide in seating gear-wheel cutters. The points of the cutter-teeth being rounding, the center cannot be found with a graduated rule or dividers, and it would be too difficult and expensive, if practicable, to make an instrument to fit and accompany each size cutter to be used as a guide in setting it. It is well known that there is a great difference in the natural faculty of mechanics for doing such work by the eye. Some can work quite accurately, while others cannot depend upon their eye for anything accurate.

Claim:
A gear-wheel cutter having a line in the center of the peripherical contour of one or more of its teeth as a guide in setting the cutter central in the gear-cutting machine.

332,118 Dec. 08, 1885 Adjustable Anvil for Micrometer Gages Frank Spaulding Providence, Providence County, RI My invention relates to the adjustable anvils of all kinds of micrometer-calipers; and the object of my invention is to avoid a certain defect in such anvils as heretofore constructed. The purpose of adjustable anvils for micrometer-calipers is to compensate for wear in the instrument so as to maintain the zero position of the sliding scale. This has heretofore been attempted by the use of an adjustable anvil which rotates throughout its entire length, so that the anvil-face is varied in position with every adjustment. It has been found very difficult to construct these adjustable anvils with absolutely true anvil-faces and such imperfection, together with the effect of wear upon the anvil-face, has rendered the accurate adjustment of the implement exceedingly difficult if not impossible. In order to overcome this defect, I construct the adjustable anvils in two parts, one of which, the face part, has only a simple sliding movement, while the other, the screw part, turns and works in the screw-thread. Thus the anvil-face preserves at all times its original position, and if there be any defect in its construction such defect may be readily and accurately compensated for.

487,410 Dec. 06, 1892 Automatic Stop for Micrometer Gages George Sylvia Waltham, Middlesex County, MA My invention relates more particularly to hand-tools such as watchmakers' micrometer-gages, calipers, and screwdrivers in which delicate measurements and the most perfect accuracy and delicacy of adjustment are essential to the best workmanship. The tools now used in watchmaking and the manufacture of delicately constructed instruments are adjusted with the greatest accuracy and are made to record or to detect the slightest variations in the work to which they are applied; but in the use of such instruments the results are found to be unsatisfactory, because varying according to the different workmen who use them, on account of differences in their nicety of touch, and often in the work of the same workman, according to the care taken by him, and also because with careful workmen much time is consumed in securing the desired accuracy. In the use of the micrometer-gage a slight overpressure upon the measuring ends when in contact with the work will expand or spread the ends apart and produce inaccuracies in the measurement of the work done. The object of my invention is to overcome these difficulties and defects by providing for micrometer-gages, watchmakers' screwdrivers, and other instruments requiring great delicacy of adjustment a device by which the forward movement of the screw turned by the hand will be stopped automatically when the desired contact has been made with the work for the purpose of measuring the same or in setting the screw or for other similar purposes. Another object of my invention is to increase the rapidity of the forward movement of the micrometer-gage screw or other forward-moving shaft under the same motion of the hand or fingers as is now used in these instruments as at present constructed. My invention has also in view the production of means by which the rotating sleeve upon the spindle of the gage or other tool may upon being reversed immediately lock with, the spindle and rotate with the same.
491,521 Feb. 14, 1893 Tail Stock for Milling Machines John W.

495,915 Apr. 18, 1893 Micrometer Gage Frank Spalding Providence, Providence County, RI This invention has reference to improvements in gages, which are particularly adapted to those of the caliper order. The object of this invention is to increase the measuring capacity of gages for making delicate measurements without increasing the traverse of the measuring mechanism. Another object of the invention is to produce a gage in which an adjustable measuring-post is carried by a traversing-indicator. Still another object of the invention is to increase the measuring capacity of a caliper gage without obstructing the anvil end of the frame. The invention consists in the combination with the traverse-screw of an adjustable measuring-post. The invention further consists in the peculiar construction of the traverse-screw having means for securing a measuring-post thereto, together with such other peculiar features of construction and combination of parts as will hereinafter be more fully described and pointed out in the claims

842,989 Feb. 05, 1907 Spiral Cutting Machine Richard T. Wingo Providence, RI WilMarth H. Thurston - patent attorney
The invention relates more especially to machines for cutting spirals in which the work is carried by a rotary blank support and is acted upon by a rotary cutter, the axis of which is at an angle to the axis of the blank-support and in which either the cutter or the blank is reciprocated parallel to the axis of the blank. In such machines the cutter should be out of cutting relation during the return movement of the reciprocating support, and this may be provided for by moving either the cutter or the work. It has heretofore been customary to throw the blank and cutter out of cutting relation by a swinging movement of either the cutter or blank support. The clearing movement with such construction is in the arc of a circle with a constant liability that the cutter may contact with the wall of the cut as the blank and cutter are thrown out of cutting relation, and the danger of such action increases as the angle between the axes of the blank and cutter increases. This objectionable feature in the prior constructions is eliminated by certain features of the present invention winch provide for a relative movement between the cutter and blank at right angles to the axes of the blank and cutter in clearing the cutter from the blank, that is to say, if the axes of the blank and cutter are arranged horizontally, as is customary, the blank and cutter are thrown out of cutting relation by a direct vertical movement either of the blank or cutter, and thus all danger of injury to the work by the cutter in clearing the work is eliminated. It is preferred to move the cutter at right angles to the axes of the blank and cutter in throwing the blank and cutter out of cutting relation rather than to move the blank, and certain further features of invention relate to the construction and arrangement which provides for such movements of the cutter. In this class of machines the blank and cutter should be in cutting relation whenever the movement of the reciprocating support is forward or in the direction of the cutting movement and should be out of cutting relation whenever the movement of such support is, in the direction of the return or non-cutting movement. To insure this, the mechanism for throwing the blank and cutter into and out of cutting relation is so controlled by the device for alternately connecting the reciprocating support with the feed mechanism and the return mechanism that the operation of such device in connecting either mechanism with the -support to reverse its previous movement results in the operation of the mechanism for throwing the blank and cutter into and out of cutting relation. Another feature of invention relates to the means for operating the mechanism for throwing the blank and cutter but of cutting relation which insures the proper timing of such mechanism under all conditions. This mechanism is driven by a clutch which is intermittently thrown into and out of operation by the cooperation of rotary and non-rotary members, the rotary member or members, as the case may be, being carried by the clutch and the non-rotary member or members being movable into and out of the path of the rotary member or members and the members being so arranged and operated that in disengaging a non-rotary member from a rotary member to throw the clutch into operation a non rotary member is moved into the path of a rotary member. Thus the operation of the devices for throwing the clutch into operation sets devices for throwing it out, so that there is no-danger of failure to throw out at the proper time or of operating improperly. Further features of invention relate to the construction of the mechanism for throwing the blank and cutter out of cutting relation and locking it in position between operations

945,901 Jan. 11, 1910 Screw-cutting attachment Frederick E. Anthony Providence, RI "The invention relates to an attachment for screw-machines, and has for its object to provide an attachment whereby screw-threads of any form, depth or pitch may be rapidly produced. Ordinarily in these machines the screws are cut by means of dies, but there is a limit to the depth and pitch of a screw-thread which can be properly and advantageously cut by a die. Heretofore when it has been desired to produce screws having threads of a greater depth or pitch than could be conveniently cut by a die, it has been customary to cut such screws in a lathe by means of an ordinary lathe-tool. But this involves repeated passes of the tool along the screw-blank, a greater or less number of passes being required according to the depth of the thread to be cut. The object of the present invention is to provide an attachment whereby threads of a depth or pitch which could not be properly cut by means of a die may be rapidly produced and with only a single passage of the cutting tool past the work..."

1,906,062 Apr. 25, 1933 Index Center John Harley , Scotland Joseph A. Miller - patent attorney
This invention relates to index centers, and more particularly relates to the indexing discs, the primary object of the invention being to enable the work to be turned throughout a greater range without changing the disc. Index discs of common usage are nominally used for dividing a circle into a definite number of equal parts (not degrees 10 and minutes) in the milling of teeth and gear wheels, and hexagonal and square milling of shafts. The method usually adopted for angular indexing is as follows:
Divide 540 by the total number of minutes to be indexed. If the quotient is approximately equal to the number of holes in any index circle available the angular movement is obtained by moving the crank one hole in 20 this index circle; but if the quotient is not approximately equal, multiply it by any trial number which will give a product equal to the number of holes in an available index circle and move the index crank as many holes as are indicated by the trial number. If the quotient of 540 divided by the total number of minutes is greater than the number of holes in any of the index circles, it is not possible to obtain the required movement for the angle by simple indexing. This shows that, only some of the angles in degrees and minutes, can be obtained accurately by simple indexing, and compound indexing, which would be more accurate, involves greater calculations on the part of the workman, and leads to errors. The above method also shows that for different angles, different discs are often required, and it is only possible to turn the work through this angle and back to zero; therefore, it is not possible to turn the work accurately through a succession of angles in degrees and minutes in many cases. If a change of disc is necessary it would be impossible to place the second disc in the same position as the first one, due to the index crank not being opposite a hole. The present invention therefore aims to provide a disk which overcomes the objection supra/and in which when milling at an off angle is required the templets which are made to a protractor and which do not give the same degree of accuracy and are more costly, are dispensed with.

Abstract:

The present invention relates to improvements in milling machines, and is herein disclosed as embodied in a manufacturing type of milling machine including a work supporting table, electrically driven and mounted on ways on a fixed base, together with a cutter spindle which is also electrically driven and is mounted on a carriage for vertical adjustment toward and away from the table. It is a principal object of the present invention to provide novel and improved means for controlling the operation of the work supporting table and cutter spindle to permit a more efficient and safe manipulation of the machine by the operator, and also to insure a high degree of efficiency and accuracy in operation. It is a further object of the invention to provide certain novel and improved features of construction and operation of the several cooperating mechanisms of the machine to produce a better and more efficient machine. With these and other objects in view, as may hereinafter appear, certain features of the invention are concerned with the provision of a novel and improved electrical control mechanism for the machine, and more specifically with the provision of an improved switch mechanism for controlling the starting and stopping of the table and spindle motors. In order to secure a more accurate control in the stopping of the relatively high speed motors utilized, one feature of the invention consists in the provision of a novel and improved viscosity switch which may be mounted directly on the armature shaft of the motor, and is well adapted for consistent and efficient operation at the high speed of rotation developed by the motor shaft. Another feature of the invention consists in the provision of electrical control mechanism for controlling the operation of a viscosity plugging switch to prevent over-travel of the switch mechanism in plugging the motor to a stop, with a consequent tendency for the motor to kick in a reverse direction. Another feature of the present invention consists in the provision of a control mechanism for braking the cutter spindle to a stop which utilizes the braking force of the motor, and causes a mechanical brake to be applied only after the motor and spindle driven thereby have been appreciably slowed down to reduce so far as possible the wear on the brake linings. Certain other features of the invention consist In the provision of a novel safety stop switch for the table motor and a jog switch for the spindle motor which serve to permit a more versatile and complete control of the operation of the machine by the operator. Another feature of the present invention consists in the provision of a novel and improved g pick-off gear case which is well adapted to facilitate the changing of gears, and is so arranged as to prevent movement of the table driving connections including the gears under power with possible injury to the operator while the gear case is open.

2,615,372 Oct. 28, 1952 Milling Machine Spindle Axial Shift Control Edward E. Coffin Providence, RI Maxwell Fish - patent attorney
The present invention relates to improvements in machine tools, and more particularly to a control device adapted for controlling the position axially of a milling cutter spindle and its axially shiftable supporting sleeve. The invention is herein disclosed in a preferred form as embodied in a horizontal-type milling machine which may be similar to that illustrated in U. S. Letters Patent to Bennett and Krause No. 2,068,840, dated January 26, 1937, for; Improvements in Milling Machines. The machine referred to, is provided with a longitudinally moving work table, a spindle support, and a milling cutter spindle disposed to rotate on a horizontal axis transverse to the direction of table movement within a spindle sleeve which is mounted on the spindle support to permit a limited axial adjustment of the sleeve and spindle relative to the table. For effecting such axial adjustment, there is provided a manually operable racking control and a manually operable clamping device which serves to rigidly clamp the spindle sleeve in its adjusted position. In the machine referred to, adjustment of the spindle axially and the clamping of the spindle in adjusted position are effected by separate rotatable control knobs located at one side of the spindle head. An axial adjustment of the spindle when made by manipulation of the manual controls referred to, would normally be maintained during the entire operation upon one or more work pieces as, for example, during the continuance of an automatic operation in which the table and work supported thereon are fed at a feed rate past the milling cutter for the performance of a milling cut thereon, and are then returned at a rapid traverse rate in the reverse direction to the starting position for the removal of the work and the substitution of a new work piece in operating position on the table. In the performance of face milling operations in which a face milling cutter is moved at a predetermined depth across the face of the work piece and is then returned at a rapid traverse rate in the reverse direction to the starting position in brushing contact with the previously milled surface of the work piece, it has been found, particularly where high speed cutters having hardened edges of cemented carbide are employed, that there is a tendency for the cutting surface to be chipped or otherwise marred by the light frictional contact with the work which takes place during the return movement.

Abstract
The electronic micrometer includes a casing defining at least an internal volume, in which are disposed a sleeve having an at least partially threaded inner surface. A screw is engaged in this sleeve and is able to be put in rotation with respect to the sleeve in such a way as to displace itself along the longitudinal measuring axis (x) of the device. There is a capacitive system of measurement for measuring the relative rotation of the screw with respect to the sleeve and for determining, starting with that measurement, the longitudinal position of the screw. The casing comprises two half-shells. At least one filiform joint allows the internal volume inside the casing to be sealed. Other sealing means are provided to prevent any infiltration of water or of dust into this internal volume. Accordingly, micrometer are protected.
