BEVEL-SHEARING MACHINE.

SPECIFICATION forming part of Letters Patent No. 568,256, dated September 22, 1896. Application filed December 3, 1895,. Serial No. 570,926. (No model.)

To all whom t may concern:

Be it known that I, HENRY C. J oNEs, a citizen of the United States, and a resident of Wilmington,DelaWare, have invented certain Improvements in Bevel-Shearing Machines, of which the following is a specification.

The object of my invention is to provide an ordinary shearing-machine with an attachment whereby the edges of the sheets may be accurately beveled, one feature of the invention being a provision whereby the angle of the bevel may be varied as desired.

In the accompanying drawings, Figure 1 is a perspective vieW of a shearing-machine with beveling attachment constructed in accordance with my invention. Fig. 2 is a transverse section of the machine on a larger scale. Fig. 3 is a longitudinal section of the platesupporting device. Figs. 4 and 5 are enlarged perspective views of parts of the same, and Fig. 6 is a view illustrating a special form of the plate-supporting device.

So far as the shearing mechanism is concerned the machine is constructed in a manner similar to those in common use, the fixed frame of the machine being represented at 1, and this frame having in the upper portion bearings for the shaft 2, which has eccentrics 3, whereby a vertical reciprocating motion is imparted to the cross-head 4, vwhich is suitably guided in bearings at the opposite ends of the machine and carries the upper shearing-blade 5, the fixed shearing-blade G being carried bya bed plate or block 7 on the base of the machine.

To the front of the machine are secured brackets 8, having top iianges 9 With T-shaped slots therein, and to these T-shaped slots are adapted bolts 10, which serve to secure in place the base-flanges of frames 11, the vertical Wcbs of these frames being tapered, that is to say, being Widest at the outer ends and narrowest at the inner ends or ends adjacent to the shearing-blades.

Pivoted to the frames 11 at their inner ends are tables 12, which are slotted,as at 13, for the reception of T-headed bolts 14, whereby disks 15 are secured to said tables. The tables 12 may be connected together in some instances to form a single table, or more than for the purpose of facilitating the calking of said edges of the plates after the same have been riveted together to produce the pipe or other structure.

The T-head of each of the bolts 14 is considerably wider'than the threaded stem or shank of the bolt, as shown in Fig. 4, and each of the disks 15 has formed in it, besides the opening 17 for the reception of the stem of the bolt, a transverse groove or recess 18 for the reception of the outer portion of the projecting web of the T-head of the bolt 14, so that any twisting or turning of the disk 15 on the bolt is effectually prevented and the pins 12 are rigidly held in proper relation to the slotted portions 13 of the tables 12.

The pins 16, when applied to the rivet-hol es in the plate to be sheared, serve as doWel pins or gagesand insure the proper alinement of the plate, so that the sheared edge of the same Will be at right angles to the line of rivet-holes.

The tables 12 are preferably provided with segmental slots 19, concentric with the pivots of said tables and adapted for the reception of bolts 20, carried by the frames 11, these bolts being provided With nuts which when loosened permit the adjustment of tables 12 to any desired angle, the tightening of the nuts securing the tables at such angle. By this means the angle of the beveled cut made by the shearing-blades 5 and 6 can be varied as desired.

When it is desired to effect the shearing of plates narrower than the space between the tables 12, I secure to said tables, by means of bolts 14, a transverse bar 21, as shown in Fig. 6, this bar having longitudinal slots 22 for the reception of the stems of adjustable IOO doWel or stop pins 16a, the shanks or stems of these dowelpins passing through the slots 22 and being provided with suitable nuts Whereby said pins may be secured in position after adjustment, the device being thus adapted for the proper support of plates of any Width likely to be found in practice and narrower than the space between the tables 12.

Having thus described niy invention, I claim and desire to secure by Letters Patentl. The Within-described beveling attachinent for shearing-machines, the saine coniprising slotted brackets projecting from the fraine of the machine at right angles to the longitudinal line of the shear-blade, and tables having portions bolted to said slotted brackets, said tables having inclined upper edges and carrying do\velpins for engagement with rivet-holesiu the plate to be sheared, sub stantially as speciied.

2. The combination of a shearing-machine having a Verticallyreciprocating shear-blade operating in conjunction With a stationary shear-blade detachably secured to the bedplate of the machine, with a beveling attachment consisting of pivoted tables project ing at right angles to the longitudinal line oi the shear-blade and carrying dowelpins for adaptation to rivetholes in the plate to be sheared, and ineans for adjusting said pivoted tables so as to Vary the angle ci' the plate to be sheared, substantially as speciiied.

3. The combination in a beveling attachnient for shearing-inachines, of the tables having slotted ribs at their upper edges, T- headed bolts adapted to said slots, and dowelpin carriers having grooves or recesses for the reception of the T-heads of the bolts, sub stantially as specified.

4:. The combination in a beveling attach- Inent forshearing-machines, of tables having their upper edges extending at right angles to the shear-blades and inclined in respect t0 the horizontal, a transverse bar secured to said tables, and stop-pins adapted to engage With said bar and with rivet-holes in the plate to be sheared, substantially as specified.

In testimony whereof I have signed my naine to this speciiication in the presence ci' tWo subscribing Witnesses.
