LOCK Foe DUMPlNG-CARS.

Specification of Letters Patent.

' Patented May 7, 1907.

Application filed January 2,1907. Serial No. 350,324.

To all whom it may concern: I

Be it known that 1, WILLIAM W. MoKEL= VEY, of Youngstown, Mahoning county, Ohio, have invented a new and useful Improvement in Locks for Dumping-Cars, 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 partial side elevation of a dumping ladle car equipped with-my invention. and Fig. 2 is an end elevation of the same with the dumping mechanism partlyin section. Figs. 3 and 4 are detail sectional views, on a larger scale, showing the lock.

. My invention relates "to dumping cars, more especially dumping ladle. cars which are tippedin either direction, and it particularly relates to-locking devices employed in securing the ladies of such cars in their upright position while the cars are being moved from. place to place on the railway tracks.

In the drawings, 2 represents the ladle supported upon its trunnions 3 on the ends of which the gear wheels 4 are keyed, the gears meshing with racks 5 on the end frame of the car. The ladle tip ing motor 6, which is applied to one end on y of the car, has a piston rod 7 which is secured on its outer end to a cross-head 8. The cross-head 8 is provided with tubular guides or bearings 9 which slide over the two guide rods 10. The guide rods 10 are secured on their outer ends to the stationary bracket or lug 11 on the end frame of the 'car, their opposite ends being held in the stationary lugs or brackets 12.

One end of a link 13, having a hole 13 on its other end and a'hole 14 intermediate of its ends is pivoted-on the bolt 8 secured to the upper end of the crosshead 8 and the link 13 is detachably secured to either of the projecting lugs 15, 15 which are on the upper end of the gear wheel 4 by means of the removable bolt or pin 16 by placing this bolt in one of the openings 13,14 and the registering opening in one of the lugs 1'5. The pin 16 is provided with a conical end having an annular groove 16'. The bolt is retained in place in the lug 15 or 15 in which it is placed, by means of the swinging latches 17 pivotally secured on each of these lugs, the latch 17 being held by its own .weight in the groove 16 to lock this pin inplace, the latch being I lifted by hand to release the pin and-permit of its removal.

To lock the ladle 2 in its upright position on the frame 18 of the car, a locking bar 19 is movably secured by means of hinges 20 on the hinge bolt 20, the ends of this bolt being secured to-the lugs 11 and 12. The ends of this locking barv engage with the face of one of the slides 9 on the cross-head 8 andthe face of one of the lugs 12 and kee these parts in their separatedposition, as s own in the drawings.

When the cross-head is attached to the ladle at the other end of its stroke, by means of the pin 16 which in such case is inserted in the opening 14 in the link 13 and the registering opening in the lug 15*, the ends of the locking bar 19 engage with the opposite end of the slide or bearing 9 and with the bracket 11 to hold the parts from movement and keep the ladle in the desired position. I

With the parts connected as shown in Fig. 1, the locking bar 19 is lifted on its hinges 20 the osition shown dotted. Fluid is then admitted to the right hand end of the cylinder 6, causing the piston 7 a and piston rod 7 to exert a pushing action through the link '13 upon the pivotal connection to the gear wheel 4, causing the ladle to lift in a counterclockwise direction until the ladle. body strikes the side of the frame member 18 which acts as a stop. The ladle is tilted back to its normal osition by admitting fluid to the other end of the cylinder in the usual manner.

1 If it is desired to tilt the ladle in a clockwise direction, the locking bar 19 is moved into the position shown dotted. The connectin pin 16 is then drawn-out of the link 13 an fluid is admitted to the cylinder to move the link 13 until its intermediate hole 14 registers with the hole in the lug 15*. The pin 16 is-then pushed into the registering openings in the link 13 and lug 15*, the piston then being at or near the left-hand end of the cylinder 6. Fluid is then admitted to the left-hand end of the cylinder causing the cross-head to pull upon the connecting link. 13 and swing the ladle in a clock-wise direction until the ladle bodystrikes the side of the frame 18. Tilting the ladle to normai .by means of one of its handles 21 until it is in p Top position is then carried out by admitting fluid to the right-hand end of the cylinder. The locking bar 19 is then moved longitudinally on the rod or hin e bolt 21 until its end strikes the lug 11. %l16l00killg bar 19 is then turned on its hinges into enga ement,

with the lug 11 and the end of the sli e 9 on the cross-head 8 and the ladle is again locked in upright position on the car, in this case with the tilting motor at the opposite end of its stroke and with the link 1 3 connected, through its intermediate'hole 14 with the lug 15 on the gear Wheel 4.

Instead of the'motive cylinder shown, an electric or other rotary motor may be employed to move the cross-head. When a motive cylinder is used, the cylinder may be movable and the piston stationary and other 1 changesin the form and arrangement ofthe tipping mechanism may be made to which my invention may be applied,

I claim 1. A ladle car having a movable cross head, with a shiftable link connected to the trunnions and a longitudinally movable hingedlocking bar arranged to contact with the cross-head and lock the ladle upright on the "car; substantially as described. I

2. A ladle car having a movable cross-head with a shiftable link connected 'to the trunnions, and a hinged locking bar, the opposite ends of said bar engaging with the crosshead, and a stationary element to lock the ladle in its normal position; substantially as described. y

3. A ladle car having a movable oross-head, with a shiftable link connected to the trunnions and a longitudinally movable hinged locking bar arran ed to engage with the cross-head and 100 the ladle upright on the car when arranged for tilting in either direction; substantially as described.

4. A ladle car having a movable cross-head, with a shiftable link connected to the truncontact with either end of the cross-head and car; substantially as described.

6. In a tipping ladle car, a ladle, a l@dl 6 tipping motor having a movable elementcone'" nected with the ladle, and a longitudinally movable locking bar arranged to contact with the movable element andlock the ladle upright on the car; substantially as described.

7. In a tipping ladle car, a ladle, a ladle tipping motor having a movable element movable lockin bar arranged to contact with the movab 0 element and lock the ladle upright on the car and arranged for tipping in either direction; substantially as described.

tipping motor having a movable element connected with the ladleland a hinged lockin bar arranged to contact with said movl ab le element and either of two stationary ,1 elements located on opposite sides of said movable element and lock the ladle upright i on the car; substantially as described.
