LADLE-CAR.

To all whom it may concern- Be it'known that I, ERWIN C. SHERMAN, of Youngstown, Mahoning county, Ohio, have invented anew ment in Ladle-Cars of which the following is a full, clear, andexact description, ref erence being had to the accompanying drawings, forming part of this specification, in which igure-l is an end view of a ladle car em- 0 ying my invention; Fig. 2 is a similar view, largely diagrammatic, illustrating the dumping movement of the ladle; and Fig. 3 is a sectional plan view showing a modified construction.

My inventionhas relation to dumping or ladle cars of that type in which the ladle is emptied by pouring from a spout located at or near the top of the ladle. In cars of this character as ordinarily constructed heretofore, when the ladle is tipped in the frame of the car there is considerable drop to the spout while pouring; and in order to bring the final position of the spout in the properrelation to the receptacle poured into, it has been necessary either to allow considerable fall to the metal during the first part of the pouring, which has resulted in great loss due to the the metal, or to lift the ladle from the car by means of an overhead crane and place it in a tilting cradle so arranged as to give a shorter-fall of the metal, or to provide a movable trough which moves with the spout on the ladle. These expedients cause considerable inconvenience and added expense in the handling of the metal.

The present invention is'designed to provide means whereby a noveltipping action of the ladle is obtained, resulting in a large decrease in the drop of the spout during the pouring operation.

In the accompanying drawings, the numeral 2 designates any usual or suitable truck of a ladle car, and 3 the frame of the car supported on the truck.

4 is the ladle, and 5 indicates a receptacle, into which the contents of the ladle are to be poured. The ladle is provided at each end with a supporting projection 6, these projections normally resting upon the supporting surfaces 7 on the end frames of the car. The ladle is provided near its top and at opposite sides of its center with the projecting trunnions 8, which rest in the open and useful Improve splashing of Specification of Letters Patent.

bearings 9 formed in the upper ends of the upwardly projecting portions 3* of the car end frames. In dumping, the ladle is tilted upon one or the other of the trunnions 8,

v according to whether it is desired to pour to the right or to the left, and as these trunnions are located high up on the car,

it will be apparent that the movement of the ladle spout 10 during the pouring op eration will be very largely reduced.

In Fig. 1 I have shown the trunnions 8 as being carried by separate castings, which are secured to the ladle. In the modificatio'u shown in Fig. 3, I have shown the supporting projections 6, which carry the usual ladle trunnions 6"*, as having integral extensions 6 upon which the trunnions '8 (corresponding to the trunnions 8) are formed. The two extensions 6* are connected by tie rod 6 and a spacer or separator 6 is placed upon the tie rod between said extensions. This construction provides a square supporting frame around the top of the ladle, which tends to prevent the top of the ladle fro trunnions 8 centered ,so that they -are always alined with the open bearings.

Owing to the high center of movement of the ladle, it is tip during the pouring operation owing to the shifting to the center of gravity. To overcome this tendency, I preferably provide the lower portion of the frame of the car with the supporting feet or projections 11, which are adapted to rest upon the supports 12 adjacent to the track 13 upon which the car travels. I also preferably provide,adjacent to the supports 12 a suitable hook 14, which will engage over the projection 11 at the side of the car opposite to that at which the pouring takes place and which serves to hold down the frame ofthe car and to prevent the car from tipping. The hook, however, may be used without the supports, or the supports without the hook,

or any other suitable means may be employed for preventing the car from tlppmg during the pouring operation. The trunnions 8 are so located that their centers are in vertical lines which fall outside of the track rails 13.
