FRAME FOR LEATHER- WORKING MACHINES.

E-PECIPICATION forming part of Letters Patent No. 340,712, dated April 27, 1886.

(No model.)

To all whom i!- may concern.-

Be it known that 1, JAMES T. FREEMAN, of Woburn, county of Middlesex, and State of Massachusetts, have in vented certain new and useful Improvements in Frames for Leather Machinery and the Like, of which the following is a full, clear, concise, and exact description, reference being had to the drawings accompanying and, forming apart hereof, in which Figure 1 is a side elevation, and Fig. 2 is a plan view, of my improved frame as adapted for glassingjacks.

Certain machinery used in the manufacture of leather-snrh, for example, as glassing and pebbling jacks-are provided with frames which are commonly constructed of wood, and since the upper part, which carries the head, requires to be rigid and to maintain its position with great exactness relatively to the bed or table on which the leather is placed, these wooden frames require to be heavy and are consequently clumsy in construction, and they require to be stayed up to the ceiling and practically built into the room in which the machine is designed to operate, and are with difficulty arranged so as to maintain the neccssary rigidity.

The object of my present invention is to provide a frame for such machines which will be s'elf-contained,aml the various parts of which will be perfectly rigid, or substantially so, with relation to the other parts; and it con sists in a frame provided with a cu rvcd brace arranged in the peculiar manner shown and hereinafter described.

A is the upper projecting arm ofa glassing' jack frame, and B is the lower portion, which supports the bed. These parts are connected with a ribbed body, the ribs being placed on the body wherever most convenient and efli cient, according to the form of the body, in view of the moving parts as pulleys, shafts, 820., to which it must be adapted, and the web downwardly and rearwardly to the base E of the frame, is an upwardly-curved brace, F. This brace may be divided, as is the casein the glassing-jack frame shown in the drawings, to make room for a pulley or other part; but it must be rigidthat is, castin one piece-or its parts must berigidly secured together, and it must be integral with or rigidly secured to the base of the frame, as at a, and to the up wardly-projecting arm I), as at d, and to the projectingarm A, as at f. In the frame shown this brace is cast with the frame and a stay, h, which forms one side of the pulley-opening, is bolted rigidly to it for convenience in constructionJ By the use of the curved brace E, which is the chief feature of my invention, secured tirml y to the rear of the base, and at its other end well out on the projecting arm A, which it is desired to render rigid, and intermediatcly to the projection D of the frame, a rigid frame, comparatively light and inexpensive, is obtained, and which can be set up easily and inexpensively and is ready for immediate use as soon as placed in position.

What I claim is- A leather-dressing machine having a projecting arm and an upwardly-curved brace integral with said arm and supporting it at its outer end, said brace extending rearwardlyeto the base of the machine, substantially as set forth.
