APPARATUS FOR REMOVING ROIiIiS FROM FRAMES O1? RdLLER-MIIiLS.

To all whom it may concern:

Be it known that I, WILLIAM a citizen. of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Apparatus for Bemoving Rolls from Frames of Roller-Mills;

' and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

, This invention relates to new and useful improvements in apparatus forremoving rolls from the frames of roller mills and comprises a simple and eflicient apparatus of this nature whereby the rolls, which sometimes are of enormous weight, may be easily and quickly picked up from their bearings and removed and other rolls carricdto and deposited within the bearings of the machine by ,suitable power driven apparatus.

The present invention comprises an apparatus of this nature having various details of construction and combinations and a1"- rangements of parts which will be hereinafter full described, shown in the aceompanying crawings and then specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a part of a rolling mill showing the apparatus for lifting the roll in' engagement with one end of the spindle of the roll. Fig. 2 is an end View in elevation of the frame showing the opening through which the rollers are moved to and from their bearings. Fi 3 is a cross sectional View on line 33 of Fig. 1. Fig. 4 is a sectional view on line 4l4l of Fig. 1, and Fig. 5 is a section on line 55 of Fig. 1.

Reference now being had to the details of the drawings by letter, A, A designate the opposite sides of the frame of a roll mill, each having openings B formed therein of greater width than the diameters ofthe rolls C, each of which has a neck I), usually about half the diameter of the roll proper. Said necks are adapted to be mounted in chocks fitted into the housings or frame and sustain the weight of the roll and the opposite end of each roll is provided with a Wobbler Specification of Letters Patent. Application filed January 8, 1814. Serial No. 810,261.

having prongs or corners, usually four in number and y which the roll is driven, the said roll, necks and wobblers being one castmg or forging. Said housings are shown as having a ilatform A. at their upper ends provided or supporting a motor which is adapted to operate means for adjusting rolls but which motor and adjusting means are not illustrated as they form no part of the present invention. i

A suitable carrier or derrick, designated by letter H, is provided at its lower end with a socket portion II, conforming to and adapted to receive one end of the roll, and K designates a derrick carrying member having a clevis L engaged by a hook N, which latter is adapted to be connected to any suitable means for shifting from one point to another on a transmission mecha nism the derrick with the roll engaged thereby. A counterbalance weight 0 is mounted on the horizontally disposed portion of the derrick or carrier I and an adjusting screw Q is mounted in threaded apertures in the counterbalance weight Cand said member K. A grooved pulley S is fixed to one end of the screw Q and over which pulley a guard S extends and a chain T passes about the grooved pulley and affords means for retating the same and the screw for the purpose of adj listing the counterbalance weight to balance the vertical leg of the carrier or derrick. A suitable stirrup, designated by letter J, is fastened to the side of the vertical leg or derrick and is provided for the insertion of an ordinary lever or bar whereby an operator may steady the carrier when"the lower end of the carrier is moved into engagement with the roll to be moved.

In operation, when it is desired to change a roll by removing the same from the frame,

the chocks are first loosened, the carrier is brought adjacent to the roll mill at the socket end and the lower part of the carrier is moved into engagement with the end of the roll. The crane hook is then raised slightly, thus elevating the carrier and the roll with it. In the event of the roll not remaining horizontal, the operating wheel S may be turned in one direction or the other, thereby causing the member K to be moved and with it the counterbalance weight to cause the carrier and load to balance. This may be done rapidly as the rollsordinarily in a mill would require only a maxiwill be exactly weight upon the horizontal end thereof. I

a carrier and likewise mum movement of the member K- afew inches in order to balance the carrier and its load. The carrier may then be bodily moved with its load in order-to remove the roll through the opening in the end of the frame and may be taken to any placedesired and deposited and a new roll replaced by reverse movement of the operation described. I

YVhen the member K is adjusted to bring the latter directly over the center of gravity of the roll held by the socket at the lower end of the. carrier,- the horizontal leg of the the axis of the roll then be truly horizontal for the upward pull by the carrier hook and the downward pull due to the weight of the roll will be coinciding vertical planes and hence the forces will be in equilibrium and avoiding any tendency to rotation. At the same time, the weight of the vertical leg of the carrier counterbalanced by the will hat I claim to be new is 1. An apparatus for removing rolls from rolling mills comprising a carrier adapted to engage the neck at one end of a roll, an adjustable member 'inwhich a laterally extending portion of said carrier is adapted to counterbalance welght be adjustably held, a upon the carrier and having a threaded aperture therein, and a screw engaging the threaded aperture .in said counterbalance weight and in said carrier supporting: memher, as set forth.

An apparatus for removing rolls from rolling mills comprising to engage the neck at one end of a roll, an adjustable member in. which a laterally extending portion of said carrier is adapted to be adjustably held, a counterbalance weight upon the. carrier and having a threaded aperture therein, a screw enga up; the threaded aperture in said counter alance Weight and in said carrier supporting member, a pulley fixed to said screw, and a chain passing about the pulley, as set forth. '3. An apparatus for removing rolls from rolling; mills comprising a carrier having at its lower end a socket portron' receive the end of the neck of a adapted to 7 roll, a supporting member mounted on a disposed portion of the carrier, ance Weight upon the carrier, said counterbalance weight and supporting member having registering threaded apertures, a screw enuaging said apertures, a pulley fixed to the screw, and an end about said pulley as set forth.
