Abstract: The invention is herein disclosed as embodied in a universal grinding machine of which the principal parts include a base, a longitudinally movable work table, and a grinding wheel spindle support which is mounted for both transverse movement with respect to the work support and for rotational adjustment about vertical axes. The grinding wheel spindle supporting assembly includes specifically a grinding wheel spindle support on which are mounted a rotary grinding wheel spindle and its driving motor, a wheel slide on which the wheel support is rotatably adjust- able, and a swivel support for the wheel slide carried on the base. Machines of this general description as heretofore constructed have been provided with adjusting means to permit a limited forward and back adjustment of the wheel support on the wheel slide, which has been found to be of advantage to increase the effective range of forward and back movement of the grinding wheel without so far extending the movement of the wheel slide as to unbalance the grinding wheel support assembly. It is a principal abject of the present invention to provide in a machine of this general description an improved means for effecting an adjustment in the position of the wheel support on the wheel slide, which adjustment may be made with a minimum of labor, which substantially increases the range of possible adjustment of position of the wheel support, and which further assures that the wheel support assembly will provide a support of maximum strength for each adjusted position of the wheel support. In carrying out the invention, a wheel support platen or turntable is mounted to turn about a vertical axis on the wheel slide and in turn provides a swivel support for the wheel support on which the wheel support is rotatably adjusted about a vertical axis which is eccentric to the rotational axis of the wheel support platen on the wheel slide. With this construction and arrangement of the wheel spindle supporting assembly, it will be readily understood that rotational adjustment of the platen about its axis on the wheel slide will have the effect of adjusting the position of the grinding wheel with relation to the wheel slide between extreme forward and rearward positions, and additionally of adjusting the position of the grinding wheel with relation to the wheel slide between two extreme positions laterally in which the grinding wheel spindle is so disposed as to increase the range of movement of the longitudinally moving work support either in one or the other direction. Claim: In a grinding machine having a rotary, grinding wheel spindle, a grinding wheel supporting-assembly which comprises a grinding wheel support, a wheel slide on which the grinding wheel support is carried, and a platen interposed between the grinding wheel support and the wheel slide having swivel connections eccentric to one another including cooperating bearing surfaces on the platen and on each of the grinding wheel support and the wheel slide whereby rotational adjustment of the platen is , effective to position the grinding wheel support including the swivel connection therewith with relation to the wheel slide, and a clamping device connected between the grinding wheel support and the w heel slide and acting along the swivel axis of the grinding wheel support with the platen for clamping the grinding wheel support, platen, and wheel slide rigidly together.

Manufactured by Chicago Specialty Mfg. Co. - Chicago IL

The gripping jaws can pivot in relation to the handle; alternate forms for the connection between the jaw structure are shown and described. The patent number and date are shown in a hardware catalog listing for the SPEEDY BASIN WRENCH produced by the CHICAGO SPECIALTY MFG. Co., but the connection between the head and handle in that tool differ from any of the details in this patent. Known example also marked "UTILITY BASIN WRENCH / PAT. NO. 2166449 (7-18-39) OTHERS PEND." Cited as a reference in patent no. 2,706,921.

Manufactured by Crown Cork & Seal Co. - Baltimore MD

This patent is for the original bottle-cap and the associated shape of bottle-top. A round metal disk is stamped with corrugations along its outer edge to create a rim extending down and leaving a flat central portion that is roughly the same size and shape as the top of the bottle. A machine is used to crimp the cap onto a bottle filled with, e.g., a carbonated beverage. Variations of this bottle-cap design are proposed for lower pressure applications such that the crimping forces are lower as not to damage the neck of a bottle intended for those lower pressures. Subsequent patents to the same inventor, relating to bottling machines and glycerin-impregnated cork material for use as a gasket, were assigned to the Crown Cork & Seal Co. of Baltimore, and they manufactured these bottle caps, and most likely licensed the patent to others as well. For the bottling machine associated with this bottle-cap, see patent 473,776. For a machine to manufacture these bottle caps, see patents 792,284 and 887,838. For other elements of this bottle-cap design see patents 468,226 and 468,259. For further improvements see patent 792,285.
