DUMPING-CAR.

To all ywhom it Imay concern:

Be it known that l, JAMES M. OKELLY, a citizen of the United States, residing in New York, in the borough of Manhattan and State of New York, have invented certain new and useul Improvements in Dumping-Cars, of which the following is a specifica-tion.

This invention relates to certain improvements in sectional dumping-cars so that the same can be quickly placed into position for dumping and easily returned into normal position and locked in this position so as to prevent any possibility of becoming 11nlocked and in danger of dropping the load, and for this purpose the invention consists of a dumping-car which is formed oi two sections open at their inner ends and pivoted at their bottoms to the frame of the car, said sections being locked together when in normal position and unlocked for dumping by a locking device that is operated by a hand-operated levermechanism in connection with a mechanism for the preliminary locking of the sections at the bottom oi the same.

The invention consists further o auxiliary locking devices for the car-sections, and o means for returning the car-sections from their dumping position into normal position preparatory to locking them together, as will be fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure l represents a side-elevation of my improved dumping-car, showing the same in normally locked position, Fig. 2 is also a side-elevation, with the covering-plate o the locking-mechanism, showing the same removed, in position for locking the car-sections, Fig. 3 is a planview of the dumping-car showing part of the bottoms oi the car-sections broken away, Fig. 4 is a vertical longitudinal section of my improved dumping-car, showing the sections of the same in tilted position for dumping, Figs. 5 and G are detail side-elevations of the locking mechanism of the car-sections, showing it respectively in locked and unlocked position, Figs. 7 and S are respectively a side-view and an end-view ol the locking-rollers of the locking-mechanism, and Fig. 9 is a side-view ol the hand-lever for operating the locking-mechanism of the car-sections.

Similar letters ol reierence indicate corresponding parts in the different figures oi the drawings.

Referring to the drawings, A represents the supporting frame ol my improved dumping-car, which is made of oblong shape, of wood, iron or'other suitable material. The car-body is made of two car-sections a, a, which are strapped at their bottoms to transverse Specification of Letters Patent.

pivot-rods al, that turn in journal-bearings a2 of the rame A, the pivot-rods being located nearer to the outer closed ends oi each car-section than to the inner open ends. The car-sections a, a, are made of wood or sheet metal andreinforced by suitable straps so the required strength is imparted to the same. ner ends of the side-walls of the car-sections are made in the form of an arc, the center of which is located in the axis of the transverse pivot-rods a, so that they do not interfere with each other when tilted for dumping or when returned into normal position on the supporting-frame A. To the center of the sides ot' the supporting-frame A are rigidly attached, by means oi angle-irons at their lower parts or bases, upright, sideplates B which extend over the inner curved ends of the car-sections so as to prevent the dropping of any portion of the load from the car-sections. The sideplates B serve ior supporting the nal locking mechanisms of thecar-sections which are arranged in recesses of the same and operated by shouldered detach-4 able hand-lever L, so as to place them in unlocked or locked position preparatory to dumping or relooking the car-sections.

The hand-lever L, has a socket-shaped end which is applied to the projecting arm of an elbow-lever Z that is mounted on a shaft in proximity to the journal-bearings oi the transverse pivot-rod a1 of the right h and carsection, said shaft extending transversely across the frame A and carrying at both ends fixed rods l, which are slotted at their outer ends and connected with pins Z3 on the lower ends of pusher-rods Z4, the upper transversely-slotted ends Z5 of U-shaped which engage pins Zi on the upper ends ot slide-frames M o-inverted U- shape. The slide-trames Mare guided in correspondlng recesses m oi the side-plates B, the lower ends of their legs m1 being made narrower and their upper ends wider, the narrower and wider portions being connected by short inclines m2 as shown clearly in Figs. 5 and 6. The slide-frames M are retained in the recesses m of the side-plates B by transverse straps n which are riveted to the side-plates and provided with central recesses nl. Between the legs of the U-shaped slide-frame, below the transverse straps n are arranged two locking rollers r, r which are guided on shoulders n2 each being made of two disks r2 that are riveted together and provided-near the circumference of their faces with ballraces and anti-friction balls 13 in said ball-races, said balls projecting beyond the circumference of the disks so as to reduce the friction of the locking rollers r rl with the shoulders n2, legs Z5 and along locking-pins o, which are arranged'at the upper ends of the curved rods Ol The inthat are guided in grooves o2 of the side-plates B and attached at their lower ends to the bottom of the right hand car-section a on which the hand-lever L is arranged, as shown in Figs. 2 and Il.

The inner disk of the locking roller r1 oi each lockingmechanism is provided with a transverse slot 15, and guided along a stationary pin r4 on the side-plate B so as to guide it in its proper motion toward the lockingpin o in the upper end of the curved rod lg. When the car-sections are in their normal horizontal positions, the locking-pins o and the slide-:frame M are locked by the rollers r, r1 as shown in Fig. 5, the hand-lever being in upright position, as shown in Figs. l and 2. In this position the locking rollers r, 1 are located below the locking-pins o and retained in this position by the wider portions of the legs of the slide-frames M, which bear at diametrically opposite points on the rollers, holding the locking-pins and their curved rods and thereby both car-sections in positively locked position.

When it is desired to unlock the car-sections, so as to permit the dumping of the same, the hand-lever L is moved towards the right, in the direction of the arrow shown in Figs. 1 and 2, so as to lift by the lever-rods l2 and pusher-rods Z3 the slide-trames M from their locked position, shown in Fig. 5, into the unlocked position, shown in Fig. 6, so that the narrow ends oi the legs of the slide-frame are brought alongside ot the lockingroll ers 1* r1 whereby suflicient lateral play is given to the latter to move away from each other and permit the locking-pins o to pass freely through between the same in following the tilting motion of the car-sections. The

rection, so as to return the slide-frames into their lowermost position, which motion forces by the nclines between the narrower and wider portions of the legs the locking-rollers towards each other and below the locking-pins, which latter are placed into the recesses of the transverse strap n, so that the locking-rollers 1 r1 are placed in contact with each other and the locking-pins so as to produce thereby the effective interlocking of the parts and the re-loeking of the car-sections. The easy motion oi the locking-rollers r r1 is produced by the anti-riction-balls in the eircumferences of the same. The antiriction-balls also permit the easy motion of the locking-rollers along the inner faces of the legs of the slide-trame, and over the shoulders at both sides of the curved rods.

The inner edge ol' the bottom of the lett-hand carsection aI is provided with a projecting lip d and the side-walls, above said lip, with forwardly projecting tongues d, both the lip and tongues being firmly riveted tojthe bottom and side-walls of the car-section. The right hand car-section a is provided with outwardly projecting studs or pins d2 that move on the upward movement of the car-sections along the under- Sides of the tongues dl until the projecting lip over the l inner bottom-edge of the right-hand car-section so as to produce thereby the tight closing at the meetingedges of the car-sections and a preliminary locking action for the same.

The lifting of the car-sections into their normal `or horizontal position is accomplished by means of short drums e, which are arranged on a transverse shaft e1 located at the right hand end of the supporting rame A and supported on standards c2 attached to the same. The drums e are connected by means of a Wire-cord c3 with the adjacent end wall of the right hand carseetion and by a wire cord e4 which passes over guidepulleys e5 a0 at the underside of the supporting-frame A with the outer end of the left-hand car-section, as shown clearly in Fig. 4. The drum-shaft e1 is rotated by means of a gear-Wheel e7 which is arranged on a short stud-shaft e supported in bearings oi the standards e2. The gear wheel e7 meshes with a pinion e on the drum-shaft C1 so as to turn the same on its axis. A hand-crank is applied to the square end of the studshaft oi the gear-wheel e7 when the car-sections are to be returned to their normal position, and the drum shaft turned by the crank so that the wire cords are wound up on the drums e and the car sections raised into their former horizontal positions. As soon as they are returned into horizontal position7 they are tightly closed at their inner ends by the tongue and pin coni nection at the bottoms of the car-sections, after which they are locked by means or' an auxiliary locking-device, which consists oi a lug f on the right hand car section a and which is pivoted to a stud f2 on the supporting frame A and turned by hand-levers f1 so that the lug f engages a projecting shoulder f3 attached by straps to the right hand car-section near the outer ends of the same, as shown clearly in FigV 1. The lug f and shoulder f3 form an auxiliary locking device for the car-section and impart a preliminary locking action to the same, which is then completed by operating the hand-lever L locking the side walls of the carsections by the final locking mechanisms to the sideplates B, so as to produce thereby the positive and final relocking of the car-sections ready for receiving tho load.

On the supporting-frame A are arranged at opposite sides inclined spring-cushioned blocks g which are guided in boxes g1 and which receive the impact of projecting stops g2 on the ends of reinforcing straps g3. attached to the side-walls of the car-sections. The cushioning blocks g serve to arrest the downward niotion of the car-sections and take up the shocks caused by the tilting of the weighted car-sections. During the tilting motion of the car-sections the wire-cords by which the car-sections are returned into their former position follow the motion of the outer ends of the carsections, as shown in Fig. 4, the wire cords unwinding from the drums e suiciently for this purpose. The final or main locking mechanisms are inclosed by suitable covering-plates N which extend over the same and which prevent the dust from entering into the working parts oi the locking mechanisms so as to preserve the same in good condition and ready for the unlocking or locking action in connection with the tilting oi the car-sections or the'returning of the same into normal horizontal position7 While the side-plates serve to retain the load in the car body and prevent any discharge of the saine at the upper adjacent ends oi the car-sections, While the tight closing of the bottomedges oi the car-sections so obtained by the bottom lip and the preliminary locking devices on the same.

When it is desired that one-half of the load should be dumped at a time, a transverse partition p is inserted above at the meeting edges of the bottoms of the carsections, the partitions being supported in suitable Ways w on the side-plates B as shown in. dotted lines in Figs. 1 and 3. 1n this case the let hand car-section has to be provided like the right-hand car-section With an auxiliary locking device b, b1, b3. For dumping the load of the right-hand car-section, its locking lug f is first released from the stop shoulder f 3 after which the final locking mechanism is unlocked by the operation by the hand-lever so as to release the car-section, drop it into tilted position by gravity and permit the dumping or' its load. The left hand car-section is then released and dumped in the same manner by unlocking its auxiliary locking-device f f1 f 3 and then tilting it by gravity as the greater part of the load presses on the longer inner ends of the car-sections. This arrangement enables the transportation oi dit'- ferent substances in the same car in case it should be required, such as different kinds oi ores, sand and ore, etc.

The advantages of my improved dumping-car are that it holds the load securely Without any loss While in transit; that the dumping-sections are firmly and positively locked together Without any possibility of release;- that the dumping operation is accomplished With great facility by first unlocking the auxiliary locking devices and then the final locking mechanisms; that the return oi the tilted car-sections into their normal position is conveniently accomplished by the return-mechanism; that the relooking oi the car-section is accomplished by the action of the auxiliary locking devices, and the iinal locking-mechanisms operated by the hand-lever; and that all the different operations are accomplished lby one attendant and from one side ot' the car-sections.

Having thus described my invention, l claim as new and desire to secure by Letters Patent.
