DUNIFING-CAR.

Specification of Letters Patent.

latented May 8, 1906.

To all whom t may concern: A

Be it known that we, ERWIN C. SHERMAN and WILLIAM W. MCKELVEY, of Youngstown, Mahoning county, Ohio, have invented a new and useful Dumping-Car, 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 sectional end elevation showing a ladle-car provided with one form of our invention. Fig'. 2 is a partial side elevation of the same. Figs. 3 and 4 are detail views of the pin-retaining mechanism; and Fig. 5 is a view similar to Fig. 1, showing another form of motor and connections.

Our invention relates to dumping cars which are tipped in either direction, more especially to ladle-cars.

The object ofthe invention is to provide connections by which a stationary motor may tilt the car in either direction, and, further, to provide simple and efficient means for holding the carin vertical position.

In the drawings, referring to the form of Figs. 1 and 2, 2 represents the ladle supported at its ends upon trunnions 3, to which are keyed gear-wheels 4, meshing with racks 5 upon the end frame of the car. The motor which tips the car is applied at one end only, and in this form consists of a pneumatic steam or hydraulic cylinder 6, rigidly secured to the framing. The piston-rod 7 of this double-acting cylinder is secured at its outer end to a cross-head 8, having two lower integral tubular guides 9, which slide over two guide-rods 10. These guide-rods are secured at their outer ends to the stationary bracket 11, and their other ends rest in holes in stationary brackets or lugs 12. To the upper end of the cross-head Sis pivoted a link 13, having a hole 14 in its intermediate lportion and also a hole at its other end. This link is removably secured to either of two projecting perforated lugs 15 on the upper portion of the gear-wheel 4 by the pin or bolt 16. This pin is preferably formed, as shown in Figs. 3 and 4, with a portion 17, having a slight taper and a conical head 18, with a grooved annular recess 19 in its rear. The pin is held in position by the swinging latch 20, 'one of which is pivoted to each lug at 21, the lug having a stop 22 to limit the lifting of the latch and the latch being normally held to lock the key by its own weight.

With the parts connected as shown in Fig. 1, when fluid is admitted to the right-hand end of the cylinder it will exert a push action through the link upon the pivotal connection to the gear-wheel, and thus tilt the ladle in a counter-clockwise direction until the ladlebody strikes the side frame member 23,which acts as a stop. The ladle is tilted back to normal position by admitting fluid to the other end of the cylinder in the usual manner. If it is desired to tilt the ladle in a clockwise direction, the connecting-pin 16 is drawn out and fluid is admitted to the cylinder to move the link until its intermediate hole 14 registers with the hole in the lug 15. The pin 16 is then pushed in through the lug 15 and the connecting-hole 14, the piston then being at or near the left-hand end of the cylinder. Now if iiuid is admitted to the left-hand end of the cylinder it will pull upon the connecting-link 13 and swing the ladle in a clockwise direction until the ladle-body strikes the frame 23 on its side. The tilting` to normal position will be carried out by admitting fiuid to the right-hand end of the cylinder. In both cases the stroke of the piston is less than the length of the cylinder,`which stopping at an intermediate point in the length of the cylinder when the ladle strikes is stopped by the frame 23 in its downward movement. In order to lock the ladle in upright position when arranged for tilting in either direction, we provide spacing-collars 24 and 25 upon the guide-rod 10, and upon a locking-rod 26, mounted in bearings 27 on the frame, we provide two latches or pawls 28. locking-rod, and their bottom portions are shaped as shown in 2 so that when they are swung forward they will rest in line with the guide 9. The depending bent handles 26 then hold them in this position. In the position shown in Fig. 1 the ladle is locked invertical position by the collar 9, which is held betweenthe spacer 24 and the latch 28. When arranged for tilting in the opposite direction, the collar 9 will be similarly held between the spacer 25 and the other pawl 28 near the central portion of the rod 26. The ladle is unlocked in either position by turning the rod through either handle 26. Instead of using These latches are rigidly secured to the y TOO a motive cylinder we may employ gearing or guiding connections for moving the crosshead. Thus in Fig. 5 the central portion of the cross-head 8 is provided with a screwthreaded hole to receive the screw 7', which corresponds to the piston-rod of the motor. This screw or worm is carried in bearings 31 in the frame, and at its other end is provided with a gear-wheel 32, intermeshing with the pinion 33, driven by an electric or otherrotary motor 34, mounted on the frame. The ladle is tilted in this form by rotating the shaft '7 in either direction, and the ladle will be locked in normal positionby the screw. The method of changing the connection of the link is the same as in the irst form, and parts similar to those of thepirst form are indicated by similar numerals with the primemark applied.

The advantages of our invention result from the simplicity of the device and the ease of changing it for tilting in either direction. The stationary portion of the motor is stationary at all times and is not shifted in changing the direction of tilting. Another advantage of our construction is that the pressure is applied to the gear-wheel at a point above the axis of rotation, so that a long lever-arm is obtained, enabling a smaller motor to be used. The apparatus maybe applied to existing ladle-cars and is eiiicie'nt and economical. Where a motor-cylinder is employed, the piston may be stationary and the cylinder movable, and many other changes may be made in the form and arrangement of the motor and connections without departing from our invention.
