METAL-TRANSFER DEVICE.

Specification of Letters Patent.

Patented April 16, 1907.

Application filed June 19, 1905. Serial No. 265.868.

tion, of a hotbed equipped with my im- E Fig. 2 is a plan, and

proved transfer device. Fig. 3 is a sectional side elevation, of the transfer device. Fig. 4 is an end elevation, and Fig. 5 a sectional elevation on the line V V of Fig. 2.

My invention relates to the class of devices for transferring metal laterally on supportingwvays; and the object of the invention is to provide a simple and'eflicient device by which metal may be moved sidewise on hot I beds or suitable supports; further, to provide a dog or pivot pushing device which may be thrown into inoperative position and held in such position without manual operation; further, to provide a pushing device which may be thrown into and out of operation at the will of the operator without manual operation of the dog or pushing device.

The further object of the invention is to prevent distorting or nicking of the metal by the action of the dog in returning.

In the drawings, 2 indicates the rail of the hotbed, and 3 the roller of the table leading from the mill to the hotbed. The hotbed is made up of a series of these rails, which are separated apart from each other, the rollers carrying the beam. or metal forwardly along the side of the hotbed. Below and between certain of the supporting-rails of thehotbed are located supporting-guideways 4, which are shown as consisting of channels with their flanges projecting upwardly. In these channels slide the transfer devices, which are shown in detail in Figs. 2, 3, 4, and 5. .Each of these transfer devices consists of aframework having an open top and bottom with side members 5 5. This frame is preferably cast in one piece with the connecting-webs 6 and 7 at its ends. Each side member is provided with bottom shoes 8 8, which travel upon the top face of the channel-web and fit loosely against the flanges, and at the top are provided U-shaped straps or

abutments

9 and 10, which are bolted to the lateral flanges 11 of the casting. Within the movable frame above described is located a shifting frame having pivoted to its ends the ropesockets 12 12. This shifting frame is provided with a front shoulder 13, which is adapted to butt against the web 6 in certainpositions, and also with a rear shoulder 14, adapted to butt against the web 7 in certain positions. The side members 15 of the shift.- ing frame fit loosely between the side mem bers 5 5 of the outer frame and receive the pin 16, to which the dog 17 is pivoted and also the abutment-pin 18. These pins are held in place by the side members 5 5 of the outer frame. The shifting frame rests upon the webs 6 and 7 andin its rear portion is pivoted the depending gravity-latch 19, the

pivot-point of this latch being above the abutment 7. The upper end of the dog 17 projects above the top of the hotbed-rails a sufficient distance to insure a proper movement of the metal when the entire device is I(Olrawn from the delivery-rollers onto the hot- At the side of the delivery-roller opposite to the hotbed are located a series of shelves or supportinguides 20, having downwardlyinclined nose portions 21.

22 indicates one of the pulleys or drums around which the wire rope 23 passes, the

ends of this wire rope being secured to the rope-sockets 12.

In the operation of the device a pulling strain applied to the moving frame in a direction to cause it to travel from the rollers to the hotbed will first pull the inner shifting frame into position shown in Fig. 3, in which position the dog of each frame will be elevated by gravity, the forward movement of the shifting frame being stopped by the shoulder 13 abutting against the web 6. A further pulling movement causes the elevated dogs to push the metal forwardly upon the hotbed. After the metal has been moved forwardly to the desired point on the hotbed the movement of the wire ropes is reversed, and the strain being applied in the opposite direction to the shifting frame willfirst slide this shifting frame rearwardly within its inclosing frame until the shoulder 14 strikes the web 7. In this movement the nose of the dog will strike the abutment 10, which will depress the dog into the position shown in dotted lines. Immediately thereafter the latch 19 will be swung up by movement over the abutment 7 and will hold the ment with the notched portion 24 of the tail of the dog.

will be held depressed.

The dogs of the several frames will thus be depressed without contacting with any beams or metal in the rear of the dogs and in its return-path. As long as the movement of the dog-supports is continued in this return direction, therefore, the dogs If it is desired to lock the dogs in this depressed position, so that they may be held in such position during their forward travel, so as to pass them under certain beams or metal lying on the rollers or table, he dog-carriers are moved back to a position where the shelves will hold the tails of the dogs and prevent the dogs tilting to raised position. A forwardpulling movement upon the ropes will then draw the dogs and their shifting frames along on the shelves until the noses of the dogs are brought under the front abutments 9 of the outer frame. In this position as long as the frames are drawn steadily forward the dogs will remain depressed and are held against tilting up by the abutments 9. Now if it is desired to throw the dogs into ope1 ative position the operator shifts the direc tion of rotation of the rope drums or pulleys so as to move the shifting frames back a slight distance, when the dogs will be released and will tilt into operative position, and the movement of the drums being again reversed to draw the frames forwardly the dogs will then act upon the metal in front of them. The dogs are held in proper upright position by the stoppins 18. It will therefore be evident that the operator may look the dogs whenever desired and then by a quick backand-forth movement can release the dogs at any point desired in the width of the hotbed. The swinging latch acts to insure the depressing of the nose of the dog sufficiently to clear the metal. If this were not used, the abutment 10 may become worn by continual use, so that it would allow the dogs to. project slightly above the top of the hotbed even when acted upon by these webs 10. The latch also acts to depress the dog far enough to engage under the abutment 9.

The advantages of my invention will be apparent to those skilled in the art. The

dogs are depressed without forcibly striking beams or metal with which they may contact on their backward return movement, and thus are prevented from nicking or injuring the beams or other metal. The shiftingframe device enables the operator to lock the dogs at the rear portion of their travel and then hold them locked until any desired point in the width of the hotbed is reached. He can then release the dogs, and thus select any beam or metal upon which he desires to act. The latch device insures the proper holding of the dogs in depressed position.

Many variations may be made in the form and arrangement of the parts without departing from my invention, since I consider myself the first to depress the dogs without contacting with the metal operated upon and also the first to provide means for lockin the dogs and releasing them at any desire point without manual operation.
