Assigned to Friedrich Wilhelm Deckel - Zug Zug Canton, Switzerland

Application in Switzerland, 17 Sept., 1958. Abstract: It is the object of the invention to provide inspection and gauging equipment of the said kind with a fitting which will permit the equipment to be adjusted and clamped with a minimum of effort and trouble either in fixed position or for rotation. Another object of the invention is the provision of means which in the case of rotatable equipment will prevent inaccuracies in alignment between individual transmission elements from affecting the true central rotation of the gauging element and from causing dislocations and jamming. The invention also contemplates the provision of means which will permit the gauging element to be affixed and rotated with the help of a single control element so that the operations required for setting up and using the equipment will be reduced to a few simple manipulations. The invention solves the objects set forth above by embodying the fitting for the reception of optionally attachable alternative measuring and gauging elements in a rotatably mounted adapter associated with means for rotating and means for clamping the same in any desired position. According to another feature of the invention the means which establish the connection between the adapter and the cooperating transmission means for imparting rotation thereto are arranged to permit relative radial displacement. To fix the adapter in a given position it is preferred to make use of a member which is fixed to the rotatable adapter, particularly in the form of a fiat ring which can be pressed against a cooperating stationary surface by means of a clamping screw. Claim: A holder adapted to releasably receive any one of various measuring and gauging optional attachments, said holder comprising a detachable head, an adapter sleeve mounted in said head so as to be freely rotatable but not displaceable in an axial direction, said adapter sleeve having a central bore including an outwardly tapering outer end portion, a gear ring mounted within said head for rotation independent of the rotation of said adapter sleeve and concentric therewith, manually operable means operatively connected to said gear ring for rotating said gear ring, a cylindrical bushing disposed partly within said gear ring and adapter sleeve, gear teeth means for rotating said bushing in response to rotation of said gear ring, a cone-shaped tubular attachment holder having an outer frusto-conical surface releasably wedged in said tapering bore end portion of said adapter sleeve, thread means for connecting adjacent ends of said holder and bushing and operative to draw said holder into said adapter sleeve in response to operation of said manually operable means, said holder being wedged in said adapter sleeve for rotation therewith in response to subsequent operation of said manually operable means.

Manufactured by Brown & Sharpe Mfg. Co. - Providence, Providence County RI
Assigned to Friedrich Deckel Praezisions Mechanik und Maschinenbau - Munich Germany

Germany application 14 May 1938. Abstract: This invention deals with guiding means for slides or similar moving parts of machine tools and similar machines. An object of the invention is the provision of an improved guide arrangement for such slides v or similar parts. Another object is the provision of guiding means which is capable of bearing relatively heavy loads without undue friction, so that the slide or similar part supported by this guiding means is movable relatively easily and freely, notwithstanding heavy load conditions. Claim: Guiding and supporting means for accurately guiding and supporting heavy relatively movable parts of machine tools and the like, said guiding and supporting means including means forming a V-shaped groove on one of said parts, means forming a V-shaped groove on the other of said parts, said grooves being faced toward each other and extending longitudinally in the direction in which the two parts are to be moved relatively to each other, and a series of a relatively large number of rollers spaced relatively closely to each other with the clear distance between adjacent rollers substantially less than the diameter of each roller, said rollers being placed between said two grooves and extending into both of them, said rollers having axial length slightly less than their diameters and certain of said rollers having their axes lying in a common plane at a substantial angle to the common plane of the axes of certain other rollers.

The components include "nose bow, "nose clamp," and inward-facing shielded "barbs." The structure of the spring-loaded shielded "barbs" was noted as being the subject of a separate patent application. In use, this design would poke the calf when it attempted nursing. The exaggerated animal drawing was a stylistic convention of the era.
