SPECIFICATION forming part of Letters Patent No. 608,829, dated August 9, 1898.

Application filed March '12, 1 8 93- To aZZ whom it may concern.-

Be it known that we, DENNIS BRENNAN, JOHN It. W IRLEY, and EVERETT GOLD- THWAIT, citizens of the United States, residing at Elkhart, Indiana, have invented certain new and useful Improvements in Devices for Bending Angle-Bars, of which the follow- Our present invention relates to an improved device for straightening the angle plates or bars of rail-joints; and the object of the invention is to provide a simple and ofby means of which the angle-bars may be the bend and at the point where they are used without necessitating their being carried to a shop or like repair-house.

The invention is illustrated in the accompanying drawings, in which- I Figure 1 is a plan view of the device a used in straightening the plate, showing a sufficient portion of a railroad-rail to illuselevation of the device, showing the rail in the fish-plate in the various positions assumed become bent or distorted. Fig. 6 is a detail In the drawings the rail is designated at 1 This an enlarged head 11", provided with holes 11 for the reception of a suitable handle for While this form of power is preferable, we do not desire to limit ourselves to The angle plate or bar to be straightened is shown at 1%, and in order to hold it spaced a suitable distance from the rail to permit the straighten it bearing- blocks 5, 6, and 7 are Serial N0. 673,623. (No model.)

employed. Of these the blocks 6 and 7 are counterparts of each other and are located one at each end of a connecting-rod 8, while receive and support the angle-bars in a num- 7 her of positions, according to the bent condi-' tion of the angle-plate to be straightened.

The forward end of the screw 11 is rounded and adapted to bear against a rounded socket in a bearing-block 10. This bearing-block has three faces differently shaped to fit the faces of the angle-bar in as many positions and has three rounded sockets in its three remaining sides for the end of the screw, as before stated.

Referring more particularly to Fig. 2, in which the parts are shown in position for bending the angle-plate, it will be observed that the bearing-blocksflG and 7 have notched or recessed portions or, and slightly-inclined forward edges b, the former offering seats for the head or upper edge a of the angle-bar, while the latter serves to support the lower edge I). The central block 5 rises only to a fraction of the height of the blocks 6 and 7, as clearly shown in dotted lines, and does not extend out so far from the rail, so that when pressure is applied to the central por tion of the under side of the angle-bar by screw 11 and pressure-block 10 the base-flange of the angle-plate is free to be forced in wardly. The upper edge, however, of the bearing-block 5 is inclined, and as pressure is applied to the plate, forcing the portion a into the seats a and bending it in at the center, as before described, the inclined surface of the block 5 tends to lift the central portion of the edge a slightly.

In Fig. 3 we have shown the angle-bar in another position, adapted to be straightened to remove a bend of a different shape. In this it will be seen that the base of the angle bar or plate rests against seats or hearing faces 0 and c, the central block 5 not being necessary in this position and not contacting with the surface of the angle-bar. It will also be observed that the block 10 has been shifted to bring its corresponding side in contact with the upper edge of the angle-bar.

In Fig. 4 the angle-plate is shown in still another position, in which it will be observed that the upper edge of the angle-bar, which is here shown upside down, rests against shoulders d of the blocks 6 and 7.

For holding the angle-plate in still another position we find it desirable to provide additional bearing blocks 13, having faces 6, adapted to abut against the inner face angleplate in the position shown in Fig. 5. These may or may not be connected, as desired, and while We prefer to place them against the this respect.

From the foregoing description it will be readily apparent that a portable and extremely advantageous device isprovidcd. By reason of thus utilizing the rail as a part of the device when in operation the number of parts to be carried around are greatly reduced and the Weight decreased to a degree which renders it possible for the workman tocarry it easily from place to place. The anof use without the necessity of sending them to the repair-shops.

It will be understood that while we have illustrated and described the invention in connection with the ordinary rail and fish-plate, We do not limit ourselves to the particular form of the rail and fish-plate, as the invention is equally adapted to rails and fish-plates of any form.

Having thus described our invention, what we claim is 1. A device for bending or straightening railroad angle-plates comprising the clamp tially as described.

2. A device for bending or straightening angle bars or plates comprising the clamp adapted to engage the rail, the connected bearing-blocks adapted to rest against the rail and having surfaces designed to sustain the angle-plate, and means for applying pressure to the unsustained portion of said an gleplate, substantially as described.

3. A device for straightening or bending angle-plates comprising the clamp adapted to engage the rail, the bearing-blocks adapted to abut against the rail and having a plurality of sustaining-surfaces adapted to sustain the angle-plate in a plurality of positions, and

means for applying pressure to the unsustained portion of said angle-plate, substan- ;tially as described. blocks 6 and 7 we do not limit ourselves in 4. A device for straightening or bending angle-plates comprising the clamp adapted to 'Eengage the rail, the central and end blocks adapted to abut against the rail, bearing-surfaces on said end blocks adapted to sustain the ends of the angle-plates, an incline on said central block designed to contact with the 3 under edge or face of the plate being straightened, and means for applying pressure to the 5 central portion of the angle-plate, substanitially as described.

gle-bars can thus be straightened at the point 5.
