FREDERICK E. MESTA, OF PITTSBURGH, PENNSYLVANIA.

BILLET-TURNING DEVICE.

Specification of Letters Patent.

Application filed September 9, 1908.

Patented Oct. 24, 1911. Serial No. 452,190.

To all whom it may concern:

Be it known that I, FREDERICK E. MESTA, of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Billet- Turning Devices, 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 top plan view of my improved device applied to a rolling mill feed table; Fig. 2, is a sectional side elevation of the same; Fig. 2 is a similar View of one portion of the cylinder which is broken away in Fig. 2. Figs. 3 and 4: are views similar to Fig. 2, showing other forms of the invention.

My invention relates to the turning of metal in connection with a rolling mill, and is designed to provide an improved turning device by which the metal will be gripped and positively turned over.

It is also designed to provide such a device adapted to turn the metal at different points in the width of the feed table and to provide a simple mechanism by which the metal is first gripped and then turned by means of the same actuating connection.

"In the drawing, referring to Figs. 1 and 2, 2 represents the side guard of the usual ingot manipulator. As shown in Fig. 1, this side guard is cut away or recessed to receive my turning device, which is pivoted thereto. This turning device consists of a wrench, the lower jaw 3 of which has a slotted pivot connection 1 with a pivot pin on the side guard.

This lower member normally rests upon a stop 5, secured in the rear of the side guard, thereby clearing the table. The upper jaw 7 of the wrench is pivoted to the lower member at 8, and is preferably provided with a ball or roller 9 in its contacting face. When not in action, these parts are in the position shown in Fig. 2, the upper jaw clearing the side guard and having a raised portion 10, abutting against the upper rear portion of the lower jaw to stop it in the open position shown. The upper jaw is connected by a pivot bearing 11, with an actuating member, which, in this form, is a connecting rod 12, pivoted at 13 to a cross head 14:, movable in a cross head guide 15, secured to an upwardly and rearwardly projecting support 16 and which confines the movement of the cross head in a right line. The cross head is connected by the pivotal link 17 with a rock lever 18, pivoted to a stationary hearing at 19. This rock arm 18 is connected at an intermediate point by pivotal link 20 with the piston rod of hydraulic cylinder 21, having a piston 22. This cylinder is double acting, one end of the cylinder being closed and the other end provided with a stuffing box 23, for the piston rod. Continuous accumulator pressure is applied through pipe 24, to the smaller eflective area of the piston, while pressure may be applied through pipe 25 to the other and larger effective area of the piston to operate the wrench.

In Fig. 2, I have shown diagrammatically an accumulator 2t from which the pipe 24 leads, and in Fig. 2 I have shown the pipe 25 as having a control valve 25*.

In using the device, the pressure being ap plied to the larger effective area of the piston, the first action will be to swing down the upper jaw of the wrench until its ball face strikes the upper face of the metal, which is indicated by dotted line at 26. As soon as the metal is thus gripped, the further pressure turns the entire wrench on its pivotal connection with the side guard, the slotted connection allowing the wrench to accommodate itself to different sizes of billets. During this turning, the entire wrench actsas a single lever, turning on the pivot of the lower member as a fulcrum. The metal will thus be turned through an angle of ninety degrees and as more resistance is offered in'turning the tighter will be the grip of the wrench. When the turning has been effected, the pressure is relieved from the face of the piston having a large effective area and the accumulator pressure then returns the parts to the ordinary position shown, first retracting the upper jaw and then turning the entire wrench back until the lower member strikes the stop. When the turned metal is moving across the table and the wrench is out of operation, the operating levers will be pulled by the force of the constant accumulator pressure and hold the wrench in position back of the side guard. This allows the side guard to sweep over the table with the wrench in the open position. In the form shown, the table rollers, indicated at 27, are rotated by a longitudinal shaft 28 having bevel gears 29, intermeshing with bevel gears 30, on the table rollers.

In Fig. 3, I show a form similar to that of Figs. 1 and 2, except that the hydraulic cylinder 31 for actuating the wrench is mounted upon the moving frame, it having suitable flexible hose connections or elbow pipe connections with the accumulator or the other source of water under pressure. In this case I have shown the piston as provided with links 32, extending to rear cross heads 83, moving in guides at the side of the cylinder, this cross head having link connection 34 with the upper wrench member.

In Fig. 4 I show another form of the device in which the lower wrench member 35 is provided with horizontal rollers 36,

and vertical rollers 37. These rollers are arranged to contact with the metal as it passes in front of the wrench. In this case I show the connecting rod 38 as pivoted to a rock arm 39, linked to a piston rod 40, common to two single acting cylinders 41,

arranged in line with each other, pressure being constantly admitted to the smaller cylinder to move the piston in one direction, and the pressure when admitted to the larger cylinder, overcoming the resistance of the smaller cylinder to move the piston forwardly in the opposite direction, depending upon the movement desired to be given to the wrench. The final position of the wrench in turning is shown in dotted lines. In this case, the lower portion 42 of the side frame acts as a stop for the lower member of the'wrench.

The advantages of my invention will be apparent to those skilled in the art. The parts are simple in character and few in number, and the jaw members are so arranged that a positive grip is obtained upon the piece to be turned, the piece itself, after being gripped, causing the jaw members to be locked to each other to turn as a single unit. The parts in their retracted position clear the feed table, and do not interfere with the transfer movements of the manipulator.

Various changes may be made in the form, construction and arrangement of the jaw members and their actuating connections within the scope of the appended claims.

While the apparatus has been described as using water or hydraulic pressure, 0bviously air or any fluid pressure may be employed as the actuating medium within the scope of the claims.

I claim: a
