.ROLL-IREIVIOVING DEVICE.

Specification of Letters Patent.

Patented Jan. 2, 1906.

To all whom/it may concern:

Be it known that I, CHARLES W. BRAY, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful R0llRe moving Device, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side elevation showing my improved apparatus in position for removing a roll. Figs. 2 and 3 are vertical sections of the upper arm looking toward the left and right, respectively. Fig. 4 is an enlarged detail view of the socket-wedge. Fig. 5 is a front elevation of the same. Fig. 6 is a top plan view, and Fig. 7 is a cross-sectional view showing the handle.

My invention relates to the removal of rolls from the housings of rolling-mills and.

the insertion of such rolls in the housing.

The object of the invention is to provide a simple and effective device by which the rolls may be drawn out endwise through the window in the housing and removed to any desired place.

In the drawings I show an overhung lever or gooseneck having an upper horizontallyextending arm 2 and a vertically-extending leg 3. The lever is preferably built up in box-girder form to provide a stiff and strong structure. The cover-plate 4 is cut away at the lower portion of the vertical leg, and within the box-girder is placed a casting or foot 5. (Shown in Figs. 4, 5, and 6.) This foot may be secured by suitable rivets, as shown, and is provided with a recessed socket 6, which is preferably of circular form,though it may be of any desired shape. This socket is designed to feed over the wabbler portion 7 at the end of the roll-neck and to provide for firmly clamping such portion in the.

socket, and I preferably employ a sliding wedge 8, which fits in a notched-out portion of the socket and may be removably held by a lug 9, projecting in an elongated recess 10. The upper overhung arm of the lever is preferably providedv with a counterweight 11, which may be secured by cutting away the top cover-plate 12 and fitting the lower portion of the weight within the box-girder. The weight may be secured by bolts 13 and is preferably provided with adjustable weights 14, held by bolts 15. The vertical portion 3 of the lever is preferably provided with a handle 16 for easy manipulation, and this may or may not be used, as desired.

In using the apparatus it is preferably hung from an overhead crane by the clevis attachment 17, and the crane is then moved to bring the socket into engagement with the projecting wabbler portion of the roll-neck in the housing. The coupling box and the brasses and chucks having been removed, as the socket is slid upon the wabbler the shoulder on the neck pushes the wedge 8 back into the socket, and thereby binds the neck within it. The overhead crane is then actuated to lift the overhung lever slightly and then moved to move the roll endwise through the window in the housing. The lower roll or rolls may be removed in a similar manner.

The advantages of my invention result from the simplicity of the apparatus and the ease of removing and replacing rolls in the housings with the least possible delay.

The device may be made in L shape or U shape or other suitable form, and many variations may be made in its from and struc- 4 ture without departing from my invention,

I claim I 1. A roll-removing device comprising an overhung lever having a socket in its lower portion arranged to receive the end portion of the roll; substantially as described.

2. A roll-removing device comprising an overhung lever having a socket in its lower portion, and a suspending device attached at an intermediate point of the upper arm over the intermediate part of the roll, when the roll is engaged; substantially as described.

3. A roll-removing apparatus comprising an overhung lever, the upper arm of which is provided with an intermediate supporting device, the leg having a socket with a wedge device to clamp the roll-neck in place; substantially as described.

4. A roll-removing device comprising an overhung lever with a suspending device intermediate of its upper arm, the end portion of said arm having a counterbalancing-weight, and the leg portion having a socket to receive the end portion of the roll substantially as described.

5. A roll-removing apparatus comprising an overhung lever device, the lower portion of which is provided with a socket arranged ICC TO to the upper lever-arm at a point outside the socket, whereby said suspending device will be over the intermediate part of the roll when engaged; substantially as described.

In testimony whereof I ha e hereunto set my hand.

CHARLES W PRAY.
