MCKINLEY BOYLE, OF NEW YORK, N. Y., ASSIGNOR TO CONTINENTAL (JAR AND EQUIPMENT COMPANY, OF NEW YORK, N. Y.

DUMPINGCAR.

SPECIFICATION forming part of Letters Patent N0. 764,417, dated July 5, 1904.

Application filed November 3, 1903. Serial No. 179,748. (No model.)

`To (1J/Z whom, it may concern.-

Be it known that I, MCKINLEY BOYLE, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented af new and Improved Dumping-Oar, of which the followingis a full, clear, and exact description.

This invention relates to improvements in dumping-cars, an object being to provide a two-way dumping-car in which continuous horse-armsv are used in lieu of horse-chains, wherebyv thereis no variationin the holdingpoints when the car-body is in normal position or at rest, thus makingthe arms superior to chains, because any shortening of one chain which may be caused by kinkingor otherwise will throw the whole upward tension of the car-body on the companion chain.

Other objects of the invention will appear in the general description.

I will describe a dumping-car embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this speciiication, in which similar characters of reference indicate corresponding partsin all the figures.

Figure 1 is an end elevation of a dumpingcar embodying my invention with the dumping position indicated in dotted lines. Fig. Q is a side elevation thereof. Fig. 3 is an end view of one of the swinging sides or doors. Fig. 4 is a detail view showing one of the horse-arm guides. Fig. 5 shows one of the hook-locks employed, and Fig. 6 is a section on the line .a of Fig. 1.

Referring to the drawings, 1 designates a car-truck on which the body 2 is mounted to tilt sidewise in both directions. As here shown, a sill or beam 3 is secured to the under side of the body and extended lengthwise thereof at the center. At the ends and at the center of this sill are lugs 4, which are mounted to swing on pins 5, supported in standards 6 on the truck. This sill or beam 3 is extended slightly beyond the ends of the body, so as to formV supports for the center end posts 7, which are secured to the ends of the body. The sides 8 of the body are mounted to swing open as the body is tilted for dumping. The said sides have swinging connection with arms 9, which extend along the end boards and have pivotal connection with the posts 7, as indicated at 10. Extended downward on the outer side of the side boards or doors 8 are metal straps 11, which at their lower endsare projected below the edges of the side-boards to engage in keepers 12. The upper ends of the metal straps at the ends of the side-boards are turned over the top of the side-boards and also are suiliciently extended to form housings over the pivotal connections between said side-boards and the arms 9.

Ooacting with each side-board at the ends of the car are horse-arms 13, which consist of continuous lengths of metal. At the lower ends the horse-arms 13 are pivotally connected to brackets 14, secured to the truck-frame, and the arms are arranged to slide through rocking guides 15, attached to the ends of the body near the bottom. As here shown, these guides 15 are pivotally connected to plates 16, bolted to the end-boards of the body. Secured to the upper end of each horse-arm is an auxiliary plate 17, which is provided with a slot 18, coincident with a slot 19 at the end of the horse-arm. Between Vthe plates 17 and the horse-arms the arms 9 are designed to pass. These slots are designed to receive a lockinghook 20, mounted to swing between lugs 21, attached to a plate 22, supported on the arms 9. The object in providing the slots to receive the pins is to permit the said pins to move up and down with the motion of the body. The slots are so made that when the body of the car is at rest in a horizontal position the ratio of the slots above the pin is to that below the pin as 1 to 2. This arrangement is for the purpose of causing an up-pull upon the horse-arms in place of downward pressure. Vhen the car tips over slightly, the pin in the horse-ar1n of the side which comes up will be tight against the top end wall of the slot` while the pin in the opposite arm will be in the middle of the slot and the only force will be acting upward.

When it is desired to dump a load, the locking-hooks 2O are to be removed fromV the horse-arms at the side opposite the dumping TOO side, and then the body will swing downward and the horse-arms at the dumping side will cause the side-board to swing to open position, as indicated in dotted lines in Fig. 1.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- Vl. A dumping-car comprising a truck, a body mounted to swing' thereon, side boards or doors for the body, swinging arms to which said side-boards are connected, horse-arms having swinging connection with the truckframe, and means for detachably and slidably connecting said horse-arms to the arms carrying the said boards.

2. A dumping-car comprising a truck, a body mounted to tilt laterally thereon, swinging side-boards for the body, horse-arms mounted to swing on the truck, swinging guides on the body through which said horsearms have sliding movement, and means for detachably engaging the horse-arms with the body.

3. A dumping-car comprising a truck, a body mounted to swing laterally on the truck, swinging side-boards for said body, metal straps on the side-boards having portions eX- tended below the same, keepers on the body for receiving said extended ends, swinging horse-arms for supporting the body in normal position, and Swinging guides on the body through which said horse-arms slide.

4. A dumping-car comprising a truck, a body mounted to swing laterally on said truck, arms having swinging connection with the ends of the body, side-boards carried by said arms, horse-arms each consisting or' a single length or' metal having swinging connection with the truck, and sliding pivotal connection with the said board-supporting arms, and guides on the body on which said horse-arms have sliding connection.

5. A dumping-car comprising a truck, a body mounted to swing laterally in both directions thereon, arms having swinging connection with the ends of the car, side-boards having swinging connection with said arms, horse-arms having swinging connection with the truck and having slotted upper ends, slotted plates secured to the upper ends ot' said horse-arms, and locking-hooks having swinging connection with the side-board-supporting arms, the said hooks being adapted to pass through the slots of the plates and arms and to engage over the arms supporting, the sideboards.

In testimony whereof I have signed my name to this specilication in the presence of two subscribing witnesses.

MCKINLEY BOYLE.
