METAL-TRANSFERRING APPARATUS.

$IECIFIOATION forming part of Letters Patent No. 745,252, dated November 24, 1903. Applicationfi ed September 11. 1903- Serial No. l'72,802. (No model.)

Figure 1 is a plan view showing a portion of a a rolling-mill plant provided with my improved transfer system. Fig. 2 is a front elevation of the transfer-carriage, showing its' relation to the charging-machine, on an en- Fig. 3 is an end elevation of the transfer-car, showing a portion of the charging-machine; and Fig. 4: is a sectional detail view showing the dog and latch mechanism on the transfer-car.

My invention relates to the transferring of objects-such as metal ingots, blooms, &c. and more particularly to transferring the metal from a heating-furnace to the feed-table leading to a rolling-mill,and it is designed to provide a simple and effective transfer mechanism whereby metal may be brought from one or more furnaces out of linewith the table into a position at the end of the table.

In the'drawings, 2 represents a rolling-mill, and 3 a feed-table leading thereto. I have shown the outer portion 3.of the feed-table as having rollers shorter than those on the forward portion, though the arrangement of the rollers or other feed mechanism may be varied.

4 represents heating-furnaces, of which there may be any desired number, these having exit or draw-out'openings 5 on the side next to the mill. In front of this line of furnaces extend three parallel rails 6, 7, and 8, on which are supported traveling chargingmachines 9. These cliargingmiachines may be of anyusual type and are employed in drawing the blooms or heated pieces of metal from the furnaces. For this purpose the machine may have tongs movable longitudinally upon a beam 10 and actuated by a hydraulic cylinder 11.

The forward portion of the charging-machine is provided with laterally-projecting brackets or supporting-fingers 12. The upper supporting-surface of these fingers is preferably inclined outwardly and downwardly, as

shown in Fig. 2, and the fingers are spaced at suitable distance apart to receive the metal ingot or piece 13 and allow the upwardly-projecting portions of the transfer-carriage to pass between them. Thecharging-machine is supported upon suitable wheels 14, travel ing upon its track.

Between the rails 6 and 7 of the chargingmachine track are located rails 15, parallel therewith and forming atrack for the transfercar 16. 'lhistransfer-car consists of a low framework mounted upon wheels 17 below the level of the fingers 12 and having mounted in brackets or supports thereon a set of rollers 18. The axes of these rollers,of which 1 have shown three, are parallel with the track and with the axes of the rollers on the rolling-mill feedtable. The plane of the upper surface of the rollers preferably intersects the inclined plane of the upper faces of the fingers 12, and the rollers are staggered relatively to these fingers.

The transfer-car is provided between the rollers 18 with two pairs of pivoted dogs 19, the

dogs of each pair being oppositely pivoted to the frame, as shown in Fig. 4. The dogs are provided with depending tailpieces 20,having fiat inner faces 21 arranged to be en gaged by the ends of tilting latches 22, pivoted to the carriage-frame between the pairs. Each latch 22 is preferably enlarged at its center above the pivot, so that the weight will hold it in either inclined position to which it is tilted. The downward movement of the latch is limited by the frame of the carriage, as shownin Fig. 4.

The transfer-table may be moved along its track by any suitable means, and I have shown for this purpose wire ropes 23 connected to opposite ends of the table and leading over suitable winding-drums,.by whichthe operator may move the car to any desired amount in either direction.

In using the apparatus a heated bloom or piece of metal is drawn out and deposited upon the fingers of one of the charging-machines, as shownin Fig. 3. The operator then moves the transfer-carriage toward this charging-machin e, and as the rollers and dogs pass between the fingers 12 the nearest dogs of each pair will tilt freely as they contact with the metal to be rolled. The transfer-carriage latches 22.

is stopped when the front dogs of each pair pass beyond the metal, and these tilted dogs then swing back to their normal vertical position under the action of gravity on their tailpieces. The carriage is now drawn back in .the direction from which it came, and the from the carriage-rollers onto the rollers of the feed-table by a suitable motive cylinder, (indicated at 24.) It will be noted that as the dogs contact with the metal and tilt in passing under it they force the latches into inclined positi0n,where they will stop thebackward tilting of the dogs 011 the return movement. The carriage may therefore be used in the manner above described in connection with the charging-machine on either side.

An important feature of the invention lies in the fact that the transfer-carriage if accidentally moved beyond the desired point will not be injured nor cause injury to the chargin g-machine. Thus if the carriage moves too far the other set of dogs will tilt idly backwardly and allow the carriage to pass on. In this case the operator will then draw the carriage back to bring both sets of dogs on the other side of the metal and then repeat the forward movement and stop this movement when the dogs are on each side of the metal, and in repeating the forward movement the forward set of dogs will always set the latch to prevent backward movement of the dogs when the carriage is stopped at the proper point.

The advantages of my invention result from the simple and efficient arrangement of the transfer-carriage. The dog system does away with the necessity for raising or lowering the transfer-carriage, prevents any accident by moving the carriage too far, and will work equally well in either direction of travel. By using the supports or fingers from which the car transfers the metal the car does not wait for the bloom to be drawn out. The capacity is therefore greatly increased, since the metal is drawn out and thereafter transferred by the car.

The fingers or supports may be made in the form of long rails or supporting-bars extending along the furnace and in front of the feedtable. In this case the dogs on the carriage would simply move the bloom along the rails without transferring the metal to the-car. I therefore use the words transfer-carriage in my broader claims as meaning a support for the dogs, but not necessarily receiving the metal upon it.

The apparatus may be used in transferring any metal or material from one point to another, and the dog system maybe varied without departing from my invention.

I claim 1. The combination with a support having separated members, of a traveling carriage having dogs arranged to transfer the metal from the members to the carriage; substantially as described.

2. A transfer-carriage having oppositelylocated tilting dogs, and means for preventing back swinging of either set of dogs; substantially as described.

3. A transfer-carriage having oppositelylocated dogs and a tilting latch between said dogs; substantially as described.

4:. A transfer-carriage having a pair of oppositely-located tilting dogs provided with tailpieces, and a tilting latch between the dogs and arranged to contact with their tailpieces substantially as described.

5. A transfer-carriage having a pair of oppositely-located tilting dogs provided with tailpieces, and a tilting latch between the dogs and arranged to be tilted by the dogs; substantially as described.

6. The combination with a charging-mm chine having separated fingers, of a transfercarriage having dog mechanism arranged to pass between the fingers and transfer the metal therefrom to the carriage; substantially as described.

7. The combination with a pair of chargingmachines having supporting-fingers projecting toward each other, of a transfer-carriage between the machines and having dog mechanism arranged to transfer the metal from either set of fingers to the carriage; substantially as described.

8. A transfer-carriage having oppositelylocated tilting dogs, both of said dogs being arranged to tilt as they pass under the bloom or metal, and mechanism for preventing the tilting of one of the dogs in the other direction when the carriage is stopped at the proper point; substantially as described.

9. A transfer-carriage having oppositelyarranged pivoted dogs, and a latch pivoted between the dogs, said latch being arranged to be tilted by the dogs and to alternately engage the tailpieces; substantially as described.

10. The combination with a furnace of a support in front of the furnace having separated members or fingers and a movable support or .carriage having mechanism thereon arranged to transfer the hot metal from a point in front of the furnace to another point laterally removed therefrom substantially as described.

In testimony whereof I have hereunto set my hand.
