Claims priority application in Germany, 21 Nov., 1962. Abstract: Designs for tracer milling machines on which both roughing operations and subsequent finishing operations are to be performed are well known in the prior art. Usually in machines of this type the same tool is used for both the roughing and finishing operations. The finishing device is normally freely movable in three directions and directly guided by hand, and is connected to the machine column by means of a clamping arm. When roughing operations are performed by the finishing device feed and depth-of-cut motions -are assigned to the work piece table. However, experience has shown that this design is not sufficiently rugged for heavy roughing operations, because the finishing device in itself must be built relatively light in order for it to be guided directly by hand during the finishing portion of the operation. For this reason, it has been proposed in the art to provide one tool each for 'roughing and finishing, each with its own feeler or stylus. Both tools, which in this case are better adapted for their respective uses, are brought into operating position alternately, usually by shifting them along horizontal guides on the machine column. How- ever, this arrangement usually results in a large cumbersome machine and it is often 'times difficult to obtain the ruggedness necessary for exact machine operation on large work pieces. It is therefore one of the objects of the invention to provide a tracer milling machine which is exceptionally rugged in construction and provides a movable tool head .designed to more favorably counteract bending moments than the tool heads of prior art tracer milling machines. Claim: A tracer milling machine of the type having a table for a work piece and a model adapted for movement in three directions comprising: a pair of machine columns disposed in spaced relation, a tool head connected for rotation about a horizontal axis between said machine columns, said tool head carrying faces disposed parallel to the axis of rotation, a roughing tool, surface means carrying said roughing tool connected to one of said faces, a first feeler connected to said roughing tool, a finishing device having a tool and second feeler connected to another of said faces, whereby said roughing tool and finishing device are alternately brought into working position above the table by rotation of said tool head.

Abstract: This invention relates to certain new and useful improvements in the constriction of tailstocks for lathes; and the invention consists in the peculiar construction and arrangements of the parts, by means of which the tail spindle is permitted to revolve with the work being turned, and it is easily adjusted and kept in alignment. Claim: A tailstock for lathes, provided with a 9 crosshead having bearings and arranged to move parallel with the bed of the lathe, a spindle revolving in said bearings, and the means, substantially as described, for sliding such crosshead and bearings lengthwise of the spindle in the tail-stock

Manufactured by Standard Wire and Iron Works - Chicago IL

"Basket" type, with flat "barbs" on the front and sides. Circumstances of time, place and construction suggest this was produced as the STANDARD Calf Weaner by the Standard Wire and Iron Works, Chicago. A different form of STANDARD CALF WEANER produced by George W. Shirk appeared in an 1890 issue of IRON AGE.
