895,056 Aug. 04, 1908 Valve and Valve Gearing Carl G. Sprado Milwaukee, WI Abstract:
This invention relates to a structure of valve-casing and valves especially adapted for use in connection with gas engines but the use of which is not necessarily limited to gas engines. The invention relates to certain specific structural arrangements of the several parts of the valve casing and valves to be hereinafter specifically described in the specification and claimed.

In the construction heretofore of gas engines it has been customary, especially in engines of the larger sizes, to form the valve as a part of the cylinder structure, or in large sections to be attached to the cylinder structure, with the result that when the engine was assembled if it became necessary or desirable to disassemble the valve structure, it became necessary to disassemble practically the entire engine. In using certain kinds of gases to form an explosive mixture for the operation of the gas engine, it is found desirable, and in some cases absolutely necessary, to overhaul the valve casings, valves and gas passages adjacent thereto in order to remove deposits of tar, etc. which have accumulated.

Claims:
1. The combination with a cylinder provided with a port of a member provided with an aperture which is smaller than said port, said member being secured to said cylinder with its aperture in alignment with said port, a valve seating upon said member, a valve casing secured to said cylinder and provided with a partition in the interior thereof to provide separate air and gas passages in said casing, the casing and its partition being provided with apertures, said apertures being larger than said member to permit said member to be withdrawn there through, a valve controlling the thoroughfare through the aperture of said partition, a-bonnet secured to said casing and closing one of the apertures therein, both of said valves being provided with stems extending into said bonnet, and means for operating said valves.

2. The combination with a cylinder provided with a port of a member provided with an aperture which is smaller than said port, said member being secured to said cylinder with its aperture in alignment with said port, a valve seating upon said member, a valve-casing secured to said cylinder and provided with a partition in the interior thereof to provide separate air and gas passages in said casing; the casing and its partition being provided with apertures, being larger than said member to permit said member to be withdrawn there through, a plate provided with a thoroughfare contracting the aperture through said partition, a valve controlling the thoroughfare through said plate, a bonnet secured to said casing and closing an aperture therein, both of said valves being provided with stems extending into said bonnet.

3. The combination with provided with a port of a member provided with an aperture, which is smaller than said port, said member being secured to said cylinder with its aperture in alignment with said port, a valve seating upon said member, a valve casing secured to said cylinder and provided with a partition in the interior thereof provide separate air and gas passages in said casing, the casing and its partition being a cylinder provided with apertures, said apertures being larger than said member to permit said member to be withdrawn there through, a plate.

4. In combination with a gas engine cylinder a valve cylinder provided with apertures through which air may pass to the interior of said valve cylinder, one end` of said valve cylinder being open to the gas engine cylinder, a core extending into the valve cylinder forming an annular mixing chamber within the valve cylinder and an annular port at the other end of the valve cylinder through which gas may pass to the annular mixing chamber, and a valve controlling the port.

5. The combination with an engine cylinder of a valve casing provided with apertures, means for partially closing said apertures, valves located within said casing and, provided with stems which project through said casing to the outside thereof, said valves and the means for partially closing the apertures in 4said casing being so constructed. and arranged with respect to said casing that they are removable from the cylinder independently from the casing.

9. The combination in an engine, of a valve, means for tripping said valve open, means for tripping said valve shut, and means for simultaneously energizing the said tripping means.
923,593 Jun. 01, 1909 Crane Carl G. Sprado Milwaukee, WI Abstract:
This invention relates to a crane adapted to handle heavy objects, and while it is capable of use with any form of apparatus where similar functions of operation are desirable, it is specially designed for use in connection with gas engines.

It is frequently desirable to remove the valve casings and valves from gas engines for the purpose of inspecting and cleaning them, and with the larger size of gas engines this operation is a very tedious one, especially when the exhaust valve casings are to be removed, as it is customary to place these casings underneath the cylinder where they can be reached only with difficulty by any ordinary form of apparatus.

The object of this invention is to produce a simple, cheap crane by which these valve casings may be readily handled and by which these valve casing may be removed from their seats for inspection and clean in and may be returned to their seats in exactly the position which they formerly occupied.

It is also an object of this invention to so arrange the crane that it can be used with the valve casing at either end of the cylinder of a double acting engine, the specific problem to be met being to provide a crane which will retain parallelism between the face of the valve casing and its seat, which object is accomplished by the apparatus illustrated, described and claimed by this specification.

Claims:
1. The combination in a crane of a support, an upright pivotally movable on the support, a plurality of arms pivotally movable with respect to said support, means connecting the arms for simultaneous movement thereof, and screw means wholly supported by said upright for actuating one of said arms.

2. The combination in a crane of an upright and means for supporting the same in position, two arms pivoted to said upright in such a manner that their free ends can move in a vertical plane, one of said arms being composed of sections adjustable with respect to each other whereby the length of said arm may be adjusted, and means connecting the arms for simultaneous movement thereof, a sleeve movable upon said upright, and supporting means uniting one of said arms with said sleeve, and means to vary the position of said sleeve upon said upright.

3. The combination in a crane of an up right and means for supporting the same in position, two arms pivoted to said upright in such a manner that their free ends can move in a vertical plane, one of said arms being composed of sections adjustable with respect to each other whereby the length of said arm may be adjusted, and means connecting the arms for simultaneous movement thereof, a sleeve movable upon said upright, and supporting means uniting one of said arms with said sleeve, said upright being provided with screw threads, and a nut engaging with the screw threads of said upright to permit the sleeve to be moved up or down.

4. The combination with a body, of an upright pivotally movable with respect to said body and journaled on said body, arms secured to said upright, a second body to which said arms are secured, and screw means wholly supported by said upright for raising or lowering said second body.

5. The combination with a body, of an upright pivotally movable with respect to and journaled on said body below the same, a second body, arms secured to said upright and to said second body, and means for raising or lowering said second body, said arms being of such length and the upright being so mounted with respect to said first body that said second body may be swung from beyond a side of said first body underneath and raised toward the same or the reverse.
923,594 Jun. 01, 1909 Gas Engine Carl G. Sprado Milwaukee, WI Application renewed 27 Jul 1908.

Abstract:
This invention relates to gas engines and the combination therewith of a specific type of valve mechanism for controlling the admission of an explosive mixture to the explosion chamber of such engines, and is primarily intended to be made use of in connection with that type of gas engine in which it is customary to use variable charges of an explosive mixture and also to admit into the explosion chamber a filling or displacing medium.

The specific valve mechanism herein disclosed is not necessarily limited in its application to gas engines but may be used wherever similar functions are desirable.

In gas engines where various sized charges of explosive mixture are admitted into the explosion chamber of the engine, While a filling or displacing medium is also admitted to said explosion chamber in order that the pressure conditions existing within said chamber may remain constant notwithstanding the differences that may exist between the sizes of the charges of the explosive mixture admitted at different times, the proper separation of the filling medium from the charge of explosive mixture, or stratification, as it is called, is of great importance in order that the entire charge of explosive mixture may be exploded together and thereby prevent a slow and comparatively useless burning of a part of the charge, thus wasting its energy. Where in an engine it is desired to maintain perfect stratification as between the charge of explosive mixture and a filling medium, it is necessary in order to obtain the most perfect results for the admission valve to en and close as instantaneously as possib1e.

It is the purpose of this invention to provide a gas engine, in which the principle of stratification is used, with valve gear for controlling the supply of the explosive mixture which operates the valve practically instantaneously, said valve operating mechanism not being dependent upon the speed of the engine for its speed of operation.


While the drawings illustrate a specific practical embodiment of an apparatus for carrying out this invention, it is to be understood that the invention is not limited to the construction shown in which springs are put under compression during a cycle of the engine when the valve is inactive, thus storing power for the instantaneous operation of the valve at the proper times in the cycle of operation. Any other mechanism equivalent to that shown and described by this application could be substituted for that herein shown and described, provided it operated the valve practically instantaneously, the time consumed in the actual opening and closing movement not being dependent upon the speed of the engine, and such a construction would be included within the scope of this invention.

Claims:
1. The combination with a gas engine provided with an explosion chamber of a gas valve and mechanism adapted during the suction stroke of said engine to operate said valve to permit the said explosion chamber to be filled by a filling medium, a charge of explosive mixture and. additional filling medium Stratified in the order enumerated, a governor responsive to the speeds of the engine for controlling the operation of said valve to vary the size of the charge of explosive mixture, and means for opening and closing said valve substantially instantaneously operating through a period of time independent of the speeds of said engine.

2. The combination with a gas engine, of a gas admission valve, a governor responsive to the speeds of the engine, and means to open and close said gas valve substantially instantaneously operating through a period of time independent of the speeds of the engine but the times of beginning the opening and closing of said valve both being determined by the speeds of the engine as indicated by said governor.

3. The combination with a gas engine provided with an explosion chamber of a main admission valve and operating mechanism therefor adapted to retain said valve open during the suction stroke of said engine, a gas valve adapted when in its closed position to permit a filling medium to flow into said explosion chamber and when in its open position to prevent such low but to permit an explosive mixture to How into said explosion chamber, means for opening and closing said gas valve substantially instantaneously operating through a period of time independent of the speeds of said engine, a governor responsive to the speeds of said engine, and means controlled by said governor to cause said gas valve to be opened sooner and closed later as the speed of said engine decreases.

1,662,511 Mar. 13, 1928 Power-transmitting mechanism Walter Geist Milwaukee, WI This invention, consisting of vee belts and matching pulleys, was intended for using an electric motor to drive an individual machine. It was manufactured by Allis-Chalmers as their "Texrope" system, and was used, for example, on Walker-Turner's TA1180B cabinet saw.
One of the advantages claimed for this invention in comparison to earlier rope-drive systems was that the shafts could be spaced much closer together. The belts were of continuous (un-spliced) construction with trapezoidal cross-section fitting into matching grooves in the sheaves. (The innermost surface of a Texrope belt was considerably narrower—coming nearly to a point—than with a modern vee belt.) Multiple belts and grooves can be combined in parallel to increase capacity.
The inventor, Walter Geist, was head of engineering for Allis-Chalmers' flour milling transmission group; despite the group's name, Geist was trying to solve power transmission problems in textile machinery, where geared and direct drive systems were too jerky which broke threads, and flat belts were high maintenance and prone to slipping. Other design goals included low cost, compactness, and safety (easy guarding). After introducing their Texrope system in 1925 they quickly realized its usefulness extended far beyond textile machinery. Meanwhile others, including Gates, had been following a similar path but aimed at automotive applications.
