ROLLlNG-IWILL.

EPEOIFICATION forming part of Letters Patent No. 308,027, dated November 11, 1884.

(No model.)

To all whom it may concern:

Be it known that I, JOHN SHARrLEssWoR'rH, a citizen of the United States, and a resident of Goatesville, Chester county, Pennsylvania, have invented certain Improvements in Rolling-Mills, of which the following is a specification:

The main object of my invention is to provide a rolling-mill with appliances for facilitating the manipulation of the plate or other iron, its return over the rolls to the fore plate,

' and its final removal from the receiving-apron or legs; and this object I attain as more fully described hereinafter.

In the accompanying drawings, which illustrate my invention as applied to a plate-rolling mill, Figure 1 is aplan view of the rolls, apron, and legs. Fig. 2 is a side View of the same, partlyin section, showing my improved mechanism for raising and lowering the apron. Fig. 3 is a diagram indicating the positions of the parts when the apron is raised for the return of the iron over the rolls to the fore plate. Fig. i is a diagram illustrating a modification of the devices for lifting the apron. Fig. 5 is a perspective view, drawn to a larger scale, illustrating portions of the apron and legs; Fig. 6, an end view (drawn to the same scale) of the legs and standard. Fig. 7 is a'perspective view illustrating the guards and their supporting-plate for thelower roll. Fig. 8 is a transverse section of the legs, showing a de vice for assisting in tilting the latter.

A A are the housings of the rolls B B, on one of which is the usual inclined fore plate, D, Fig. 2, and on the other the apron E, with the extension F, or, as it is usually termed, the legs.

The apron and legs are constructed, in the usual manner, of longitudinal bars united by cross bars or braces of round iron, on which are mounted anti-friction rollers e c, with their intervening thimbles, to facilitate the move ment of the iron thereon.

I construct the devices for elevating the apron so that the latter will be raised to an inclined position to facilitate thepushing back of the iron over the rolls, and in order to adapt it for use on different kinds of work I provide devices for varying this inclination of the apron.

cured the usual two lifting-bars, E E Figs.

' 1, 2, and 6, to the opposite ends of which are pivoted pairs of connecting-rods G G. To the ends of the forward bar, E, are also secured eyes adapted to guide-rods 6, Figs. 1 and 2, on the housings, to guide the apron vertically. The pair of rods G are connected to the outer ends of arms or levers H, keyed to ahorizontal shaft, I, Fig. 2, mounted in fixed bearings, and forming the fulcrum for the levels. The other pair of rods, G, are connected, by preference adjustably, as hereinafter described, to the pair of levers H at points nearer their fulcrum, so that for a given movement of the levers H on their centers the side of the apron E adjacent to the rolls will be moved to a less extent than the side away from the rolls; consequently, when the levers H are moved to raise the apron, the latter will be raised from the horizontal position shown in Fig. 2 t0 theinclined position shown in Fig. 3. To accomplish this movement of the shaft I and its levers H and the apron, an arm,

J, may be secured to the shaft I at a suitable distance laterally from the rolls, apron, and legs, and this may be connected by a chain to the piston-rod of a steam or hydraulic cylinder, J under the control of one of the workmen. If the front end of the legs'F be'jointed to the apron, that end of said legs will be raised with it, as indicated in Fig. 3, the legs being hingedv to the apron to allow of the movement, as hereinafter described. If preferred, however, the legs may be unconnected with the apron, and the latter lifted without disturbing the legs.

As I have said, I prefer to make the connections of the pairs of rods G to the levers H adjustable, the purpose being to thereby permit of a variation in the extent of tilt imparted to the apron.

As adjusting devices I have shown in Fig. 2 a series of notches formed in the levers H, and pins on the rods G, which latter are controlled by arms on a transverse shaft, 9, carrying an adjusting hand-lever, 9. By adjusting this hand-lever 9' so that the pin is placed opposite a notch near the fulcrum of the lever H, the outer end of the apron will.

end of the rod Gbe adjusted to a position away from the fulcrum of the lever the apron will be inclined but little, if at all. The position of the shaft I with relation to the rods G G may be reversed, as indicated in the diagram, Fig. 4, so that the desired result will be accomplished without crossing the said rods, the forward rods being in both cases connected to the arms H nearer the fulcrum than are the rods G. The connection of either or both pairs of rods with the said arms may be adj ustable, and this by detachable pins or other devices, as will be readily understood.

In order to facilitate the removal or discharge of the iron from the legs F after the last ass, I mount the legs so that they may be ti ted to position indicated by dotted lines in Fig. 6. For this purpose the outer end of the legs is hinged to the upper end of a braced standard, K, having a pivotal connection with supporting-lugs It It on a suitable foundationblock, L, to allow of the necessary movement of the legs when the apron is raised. The upper end of the standard is curved outward, as shown in Fig. 6, in order to allow the legsto be tilted to the vertical position indicated by dotted lines.

, As shown in Fig. 5, the front end of the legs F is connected to the apron by a bolt, d, adapted to swivel in a stirrup, b, which in turn is mounted on the outermost round iron cross-bars of the apron, so as to be capable of a movement thereon to form a hinge-connection as well as a swivel between the legs and apron. The legs F are held from turning on these centers by a crankedhandle, M, pivoted to the front end of the legs at n, and fitting between jaws m on the bar E, and retained byapin, m. When the iron after the last pass is discharged from between the rolls onto the legs F, the workman, after withdrawing the pin m, turns the hand-lever M from between the jaws m, and by means of the lever tilts the apron over, Fig. 6, so as to throw the rolled plate or other iron over onto the ground.

It will be understood that this feature of tilting the legs may be applied to rolling-mills, whether such legs are capable of being elevated or not.

In order to bring the anti-friction rollers on the apron as close as possible to the lower rolls, I mount these rollers on the extreme front edge of the apron, as well as on the.

cross-bars farther back, and I further construct the guards U, which have their front edges resting on the lower roll and their rear edges on the transverse beam V between the housings, in the manner shown in Figs. 2 and 7 -that is, I form a depression, a, in the guard as close to the roll as practicable, and the front U are widened, so as to join each other where they bear on the roll, and insure even wear of the latter. Each guard is provided with a tongue, w, fitting into a corresponding pocket in the beam V, Fig. 10, a recess, 1), being formed in the back of the pocket, to receive filling-pieces '0, to adjust the guards forward as their front edges wear away.

With reference to the tilting of the legs, I

may also combine with the latter a device shown in Fig. 8, to relieve the workman when the weight of iron makes it too heavy for him to tiltthe legs by means of the handle M. I pivot to the edge of the legs, near the apron, a hooked rod, T, and to the ground'or other fixed point I secure a corresponding eye, 15; but the hook is normally kept away from the said eye by a spring, t. When it is desired to employ the device, however, the workman simply pushes the hook into the eye, and the apron and front end of the legs are then raised by the elevating mechanism above described; but the edge of the latter being held by the hook, the legs will be thereby tilted, as shown in Fig. 8.

The devices may be reversed, if desired, the eye being on the legs and the hooked rod pivoted to the ground.

2. The combination of the rolls and movable apron of a rolling-mill with pairs of rods G G, connected to the said apron, and a fulovum-shaft, I, having arms H H, to which the said pairs of rods are connected, one pair nearer the fulcrum-shaft than the other, substantially as described. V
