Turret-type tool post
|
Gordon J. Benes |
Chicago, IL |
This tailstock-mounted tool turret "is easily adjustable to train or set tools in desired positions or directions." This design was quite successful and was the main product of Enco Mfg. Co. of Chicago (not to be confused with a later company of the same name that sold offshore machinery). |

Adjustable Indicator Holder
|
Charles A. Usiskin |
Chicago, Cook County, IL |
Abstract:
This invention relates generally to an indicator holder, and more particularly to a fine adjust indicator holder, capable of incrementally varying the position of an indicator device mounted thereon. Still more particularly, this invention pertains to a fine adjust indicator holder with a magnetic base. In the past, indicator devices such as, for example, those used by tool makers and operators of milling machines, grinders, etc. to determine surface irregularities were, on the most part, unreliable if any high degree of accuracy was required. This was due primarily to the difficulty in being able to precisely control the movement of the indicator device over a particular segment of a surface, especially a curved surface. Hence, for accurate measurements, the manual manipulation of the positioning of the indicator device by itself or when mounted on a holder was, of course, out of the question. To overcome this inaccuracy problem, various prior indicator holders were devised which included adjustable features. For example, some of these indicator devices comprised an indicator arm whereto an indicator device was attached. The indicator arm was slidably adjustable along a mounting post in order to vary the position of the indicator device. Although an improvement, these adjustable indicator holders did not provide the high degree of control over the mounted indicator device that was required for extremely accurate measurements.
Claim:
An indicator holder for supporting and controlling the movement of an indicator device comprising: a mounting post; an indicator arm having a pair of split apart section: with inner ends, said arm being slidably associated with said post; means for releasably securing one of said sections toa pre-selected point along said mounting post, the other of said sections supporting said indicator device; and a fine adjustment means fixedly associated with ar inner end of each of said sections and having the capability for incrementally varying the position of said section of the indicator arm supporting the indicator device, said fine adjustment means comprising: 30 a pair of plate members, each of said plate members being fixedly connected to said inner enc of one of said sections; a fulcrum associated with each of said plate members to provide a pivot point for the same, said fulcrum being positioned between opposed surfaces of said plate members; resilient means associated with said plate mem-hers and normally biased to position the sector of said arm at the free end thereof into one or two extreme positions; and a fine adjust control for incrementally varying said last-mentioned section between said two extreme positions. |

Instrument Clamp
|
Charles A. Usiskin |
Chicago, Cook County, IL |
Abstract:
Test indicators are used for various purposes such as measuring the flatness of a surface. In order to make such a measurement, the indicator is mounted on a stand that carries an upstanding support rod. The mounting of the test indicator which may have any one of a number of types and sizes of mounting means, is effected by the use of an instrument clamp. For example, the test indicator may include a projecting round post having one of a variety of diameters and/or a dovetail-shaped tenon. Also, the upstanding rod carried by a stand used to support the test indicator may have any one of a number of diameters.
In the past, mounting clamps that have been available on the market have not been universal in the sense that they could not accommodate all of the various sizes and types of mounting means on the instrument and the various sizes of support rods and types of stands. It is therefore an important object of this invention to provide an instrument clamp that is truly universal, that is, it can be used to mount on a stand a test indicator having a variety of sizes and types of mounting means. Another object in connection with the foregoing object is to provide the clamp with adjustable openings to receive respectively instrument parts and upstanding support rods of various sizes. Yet another object of this invention is to provide an instrument mounting clamp which can he loosened and tightened with ease, yet providing secure connections between the instrument, the clamp and the support rod. With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel features and construction, arrangement, and a combination of parts hereinafter fully described, illustrated in the accompanying drawings and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of the structure and the method may be made without departing from the spirit or sacrificing any of the advantages of the invention.
Claim:
An instrument clamp for mounting on a support post an instrument that carries a projecting post, said clamp comprising: a first portion having a first opening therein for selectively receiving one of the posts; a second portion having a second opening therein for selectively receiving the other one of the posts, a third portion having a dovetail-shaped mortise extending therethrough for receiving a dovetail-shaped tenon on the associated instrument, means operatively connected to said portions for adjusting the size of both of said openings by substantial amounts and for adjusting the size of said mortise, whereby said clamp is operative to mount an instrument carrying a post that may have diverse sizes to a support post-that may have diverse sizes. |
