'SHIFTING DEVICE FOR FEED-TABLES OF ROLLING-MILLS.

SPECIFICATION forming part of Letters Patent. No. 364.392. dated June 7, 1887.

Application filed March 2, 1857. Serial No. 229.396. (No model.)

To aZZ whom it may concern.-

Be it known that I, READE W. BAILEY, of Pittsburg, in the county of Allegheny and State of Pennsylvania. have invented a new and useful Improvement in Shifting Devices for Feed-Tables for Rolling-Mills; and I do hereby declare the following to be a full, clear, and exact description thereof.

The object of my invention is to provide means for shifting metal ingots on the feedtables of rolling-mills.

In the accompanying drawings, Figure 1 is a plan view of the feed-table and shifting meclr anism, part of the feed-table being broken away for clearness of illustration. Fig. 2 is a side view of Fig. 1. Figs. 3 and 4 are side views of modifications.

Like symbols of reference indicate like parts in each.

In the drawings, 2 2 represent a horizontal series of driven feed-rollers, which constitute the ordinary feed-table of a two-high set of rolls. The rollers are j ournaled in stationary bearings 1. A detailed description of their arrangement is unnecessary, as it is well understood by persons skilled in the art. J ournaled in suitable bearings below the feed-table 2 is a shaft, 3, which extends transversely to ,the feed-rollers.

4t 4 are short levers or arms, which are keyed to and project from the shaft 3. At the ends of the arms I there is a horizontal shaft, 5, which is pivotally connected with the arms and is parallel with the shaft 3.

6 are fingerbars, which are keyed at their lower ends to the shaft 5 and project up between the spaces of the feed-table. I show three of these fingerbars, though any suitable number of them may be used. To one of the finger-bars-say the middle one--is attached a link, 7, which is connected by means of an intermediate link, 8,to the piston-rod 9 of a hydraulic cylinder, 10.

i 11 is a second hydraulic cylinder, whose piston 12 is connected by a link, 13, to a lever, 14, which is keyed to the shaft 3.

15 is a guidebar, which at its lower end is loosely connected with the shaft 3, and at its upper end is loosely connected with thejoint between the links 7 and 8.

The operation of the device is as follows: In Fig. 2, let 16 represent a metal bloom or ingot lying upon the fcedtable, by which itis moved up to the rolls. Suppose now that it is desired to move the bloom laterally on the feed-table so as to bring it opposite to another pass of the rolls. The hydraulic cylinder 10 is put into operation so as to draw back its piston 9. on the links 7 and S and moves the finger-bars 6 radially on their axis 5 in the direction of the arrow 1). The finger-bars push the bloom laterally on the table, and when it reaches the desired position the engine 10 is stopped. Now, if it be desired to move the bloom in the direction of the arrow 0, it is necessary to shift the finger-bars from the right to the left side of the bloom. To do this the pistonrod 12 of the engine 11 is projected. This turns the shaft 3 by means of the lever 14, and

throws the lever 4 downward in the direction of the arrow (1. The downward motion of the 1ever4 is continued until the upper ends of the linger-bars 6 are brought below the level of the feed-table. The motion of the hydraulic engine is then checked and the engine 10 is put in motion so as to retract its piston-rod 9. This draws the finger-bars 6 to the left beneath the ingot 10. \Vhen the bars have passed the ingot, the engine 10 is stopped and the piston 12 is drawn back, so as to raise the fiuger-bars again above the level of the feed-table. The ingot can then .be shifted by projecting the piston-rod 9. If it be desired to upset the ingot upon the feed-table, the piston rod 12 is projected so as to drop the fingenbars 6 below the level of the table, and by motion of the piston-rod 9 they are brought directly under neath the edge of the ingot. The bars 6 are then raised by retracting the piston-rod 12, and by bearing on the edge of the ingot, ofl the center line, they tip or upset it on the table and bring another side thereof uppermost.

The apparatus is simple in its construction, and is very easily operated. By its use the labor of shifting and feeding the ingots to the rolls is greatly facilitated- The form and arrangement of the parts of the machine may be chan ed somewhat by the skilled mechanic without departing from The movement of the piston draws the principles of my invention. For example, in Fig. 4 the piston-rod 9 is connected with the lever 6 by a slotted connection or yoke, 17, which takes the place of the link 7 of Fig. 2 in imparting the radial motion to the lever. In order to give the lever its vertical motions I journal it' in a block or bearing, 18, which is movably mounted between vertical fixed guides or slide-bearings 19. The lever 4 is loosely connected with the block 18, and is adapted to give it a vertical motion between the guides 19 when it is actuated by the hydraulic engine 11.

In Fig. 3 the radial motion of the lever 6 is had in the same way as in Fig. 4. To get the vertical motion, instead of using the intermediate levers, 13, 14, and 4, I set the hydraulic engine 11 in an upright position and connect its piston directly with thejournalblock 18. The bar 6 is then movable vertically with its bearings directly by motion of the hydraulic piston.

l. claim- 1. As a device for shifting ingots or blooms on the feed-table of a rolling-mill, the combination, with the feed-table, of a radially-movable shifting bar or lever which projects be tween the rollers of the table above the level thereof, substantially as and for the purposes described.

2. Asa device for shifting ingots or blooms on the feed-table of a rolling-mill, the combination, with the feed-table, of a radially-movable shifting-bar, 6, arranged beneath the table, and mechanism, substantially as described, connected with the shifting-bar and connecting the bar 6 to a motive engine, and

the guide-bar 15, connecting the link 7 with the axis of the rocking-lever, substantially as and for the purposes described.

In testimony whereof I have hereunto set my hand this 28th day of February, A. D. 1887.
