SPECIFICATION forming part of Letters Patent No. 717,622, dated January 6, 1903.

Application tiled December l2, 1901. Serial No. 85,589. (.No model.)

To MEZ wtont t may concern/ .Be it known that l, MAncELLUs REID, residing at Providence, in the coun'tyof Providence and State of Rhode Island, have in- '5 vented certain new and useful Improvements in Frames for Tire-Drawing Machines, of which the following is a full, clear, and exact description such as will enable others skilled in the art to which it appertains to make and io use the saine.

My invention relates to a frame for a wiredrawing machine; and its object is to provide a construction which shall be compact and of small number of parts and especially adapted to withstand the varions strains to which it is subjected in the operation of wire-drawing. I attain this object by the construction illustrated in the accompanying drawings, inV which- Y Figure lis a side elevation. Fig. 2 is an end elevation. Fig. 3 is a top plan; Fig. 4, a transverse vertical section, and Fig. 5 a longitudinal horizontal section.

Throughout the drawings similar reference characters refer to similar parts.

The various members of myimproved frame are preferably of cast-iron, although they may be formed in any desired manner. The frame comprises two side members or uprights, each cast in one piece, as best illustrated in Fig. 1, and having end uprights 1 l in the form of angle-irons, base-pieces 2, center pieces 3, which are formed at their upper and lower ends as lll-beams 4 4, connected by a web in the shape of a 'T-beam 5. The upper ends of these side members are flanged or bent inwardly, as at 6, and rabbeted to provide seats for a top plate. A lower tie-piece connects the side members at their lower ends and is provided with flanges which are connected to the tlanges ou the lower I-beams 4 4 by bolts or otherwise. Tie-piece 'Z has formed therein a journalbearing 8, adapted to provide a bearing for a horizontal line-shaft,fromv which power is supplied to drive the wire-drawing drum. A casting 9, bolted to the tie-piece 7, provides a cap for the line-shaft bearing and likewise a socket or step-bearing 10, adapted to receive a vertical spindle on which the Wire-drawing ing-bolts can be located in readily-accessible 6o position. Through lugs 13, extending upwardly from web l1, additional securingbolts are passed for connection with the side members. Web ll carries, cast integrally therewith, as shown, an upwardly-extending sleeve 14, which furnishes an additional bearing and guide member adapted to support the drum-spindle. The side members are further bound rigidly together by cap or cover plate 15, the opposite sides of which 7o rest in the rabbeted seats 16 on the tops of the side members, being secured thereto by bolts which pass down through the coverplate' and the inwardlyprojecting danges of the side members. It will thus be seen that the side members are rigidly held together by the two tie-pieces, and further bound together and likewise prevented from buckling inwardly understraiu by the cap-plate.

A large circular hole is out in the top of this 8o cap-plate, which is adapted when the wiredrawing block is assembled to jreceive the iiange of theAdrawing-out drum, or, if desired, of the wire-drawing drum, thereby allowing said drum or drums to be brought into close proximity to the upper tie-piece. Holes 17 17 are provided on diagonally opposite corners ol' the side members for the reception of pivot-pins for a die-box. Flange or drum 12 is extended at 1S to pro- 9c vide a bearing for an auxiliary spindle used for, driving a drawing-out druinfrom the line-shaft. The sleeve 14, which is integral with or rigidly connected to the upper tiepiece, and accordingly rigidly connected with 95. the whole framework, extends well above the upper surface of the cap-plate and accordingly well above the point at which the strain upon the wiredrawing drum would normally come in operation. Thus a conroo struction is provided in which the strain of wire-drawing is absorbed by a sleeve rigidly connected with the framework instead of being transmitted, as in the usual construction, to the vertical shaft, which carries the drawing drum or drums. This, in connection with the special stiffening construction described, forms an important part of my invention, as it enables the strain upon the machine to be distributed evenly throughout the whole framework and to a great extent prevents breaking down in use. Castings 19 19, bolted to the sides of the drum 12, furnish bearings for a horizontal shaft adapted to be used as a rock-shaft for throwing a clutch for starting the drum.

It has not been deemed necessary to illustrate all the parts of the wire-drawing block in the present application, as such illustration would only serve to obscure the invention which is claimed herein, which is lilnited to the peculiar construction of framework. Such frame is specially adapted to be used in connection with a wire-drawing block such as'described in my application now pending, Serial No. 66,202, tiled June 27, 1901, which application discloses a construction of framework in some features similar to that of the present application. It will be understood, however, that I am not limited to the use of this invention in connection with the special block in the application above noted, inasmuch as it may be adapted with slight modiications to a variety of wire-drawing machines without altering its essential characteristics.

Having described my invention, what I desire to secure by Letters Patent is- 1. A frame for a wire-drawing machine comprising 1two side members, upper and lower tie-pieces, the lower tie-piece being provided with a bearing for a line-shaft, and a step-bearing for a vertical shaft the upper tie-piece being provided with an elongated bearing in alinement with said step-bearing, whereby the transverse strain caused by wiredrawing operation is absorbed by said elongated bearing at a point above the normal line of draft of the machine, and a cap-platev cut out to encircle said sleeve and acting as a supplementary binding-piece between said side members.

2. A frame for a wire-drawing machine, comprising two side members composed of upright end pieces 1, 1, on center piece 3, base and top pieces 2 and 6, tie-pieces 7 and 11 between said side members and having anges adapted to be bolted to the flanges of said side members, bearing 8 in connection with tie-piece 7, cap 9 therefor having socket 10 therein, stiffening-drum 12 in connection with the tie-piece 11, and elongated sleeve 14 integral therewith, substantially as set forth and for the purpose described.

8. A frame for a wire-drawing machine, comprising two side members composed of the upright end pieces 1, 1, center piece 3, base, and top pieces 2 and G, tie-pieces 7 and 11 between said side members and having flanges adapted to be bolted tothe flanges ot' said side members, bearing S in connection with tie-piece 7, cap-piece 9 therefor having socket 10 therein, stiffening-drum 12 in connection with tie-piece 11, and an elongated sleeve 14 integral therewith, and a cap-plate 15 resting in rabbets in the side members and rigidly bolted thereto, substantially as and for the purposes set forth.

In testimony whereof I affix my signature in the presence Of two witnesses.

MARCELLUS REID.
