TOBIAS CHNAPKO, 0F MACDONAL'ION, PENNSYLVANIA.

DUMP-GAR.

Application filed April 20, 1918.

To all whom it may concern:

Be it known that I, Tomas CHNAPKO, a subject of the King of Hungary, residing at Macdonalton, in the county of Somerset and State of Pennsylvania, have invented new and useful Improvements in Dump-Cars, of which the following is a specification.

This invention relates to new and useful improvements in door controlling means for dump cars and the principal object of the invention is to provide means for automatically opening each pair of doors of a plurality of chutes located in the bottom of the car.

Other objects 'of the invention are to provide means for actuating said devices by an obstruction placed along the track. means for throwing such devices into and out of operative position and other means for closing said doors actuated by another obstruction placed along the track.

Another object of the invention is to pro vide a device of this character which is simple and durable in construction, reliable and etiicient in operation and one which can be manufactured and placed upon the market at a minilnum cost.

The invention also consists in certain other features of construction and in the combination and arrangement of the several parts,

to be hereinafter fully described. illustrated in the accompalrving drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote. like or corresponding parts throughoutthc several views. and in which Figure l is a side view showing the invention in use on a car with the doors closed.

Fig. 2 is a bottom plan view.

Fig. 3 is a view similar to Fig. 1 but showing thedo'ors in open position.

Fig. 4 is a detail view.

Fig. 5 is a side view showing a modificw tion of a device for closing the doors.

Fig. (3 is a detail view of the arrangement of operating cables or chains.

Fig. 7 shows a modification of an arrange Merit of these cables.

Referring more particularly to these drawings, 1 indicates the car body provided with four dumping chutes These chutes are of wedge shape, as usual, and are each closed by a pair of doors 3 hinged at their upper ends: to the bottom of the ca as at Specification of Letters Patent.

4. One door of each pair has a pair of lugs 5 at its free end between which is pivoted a. latch 6 which is adapted to engage the end of the other door, said end having a keeper 7 thereon with which the latch engages. A spring 8 engages with said latch for forcing the same into engagement With the keeper on the other door and I prefer to enlarge the rear part of said latch as at 9 so that the action of gravity will tend to keep the latch in engagement with the keeper. If desired this part of the latch may be weighted. A link or arm 10 is pivoted to one edge of each door intermediate its ends and the upper ends of these arms are connected together by a pin 11 which is movably mounted in a slotted bracket 12. By this means the doors are caused to move in unison and the slot 12 in the bracket. is made of such a length that the arms 10 will prevent the doors from swinging open to a position beyond the vertical, as clearly shown in Fig. 3.

The innermost doors of the two pairs on each side of the car are provided with latches and I provide means for actuating said latches in unison. These means consist of a rod 13 journaled in brackets lat secured to the under side of the car. This rod is provided with a pair of cranks 15 to which the operating cables or chains are secured. 17 indicates brackets secured to the bottom of the car and extending downwardly and supporting rollers 18 over which said chains extend. Each latch is connected with a crank 15 by a pair of cables, one 'able 16 passing upwardly from the latch over one of the pulleys 18 to the crank and the other cable passing upwardly from the latch over another pulley arranged along side the pulley just mentioned and from this pulley the cable 16 passes to a pulley on the opposite side of the rod 13 and from this pulley the cable passes to the crank. lln this way all of the doors will .be opened sin'ml'taneously by a partial rotation of the rod 13 in either direction.

The rod 13 is provided with a forked end 13 projecting beyond one Side of the car and a bar 20 is pivoted in. said forked end. The end of this bar is adapted to contact with a post 21 located along the track at a point where it is desired to dump the car so that as soon as the bar 20 strikes said post the rod 13 will be given a partial rotation so as to open all the doors and thus in Fig. 4.

dump the load. I provide means for holding said bar in raised position so as to avoid danger of the unintentional opening of the doors and such means consists of a spring dog 22 carried by the end of the rod 13 and engaging recesses 23 in the pivoted end of said bar. Said recesses are so located that the bar will be held in vertical position or in horizontal position. In this latter position the bar will engage the under side of the rod 13 as shown in dotted lines Slightly beyond the dumping location I provide means for closing the doors, such means consisting of an inclined post 2* placed along the track at a suitable distance from the dumping location and arranged to contact with the first door of the series so that said door will be closed by said post, and through the connections before described will close all the other doors, the latches being thrown in engaging position when th doors are closed. w

Fig. 5 shows a modification for closing the doors. In this case the pin 11' is extended outwardly beyond the arms 10' so as to contact with an inclined bar 24: supported along the track by means of the posts 25. In this form when the car leaves the dumping location the pin 11 will strike the inclined bar 24 and will be moved up the same and thus move upwardly in the slot 12". This will cause the doors to swing shut as before described to permit the latches to engage the doors to hold them in closed position.

In the modification shown in Fig. 7 instead of the cranks on the rod I provide the same with cross bars 26 to which the chains or cables 27 are connected at the ends thereof. These cables pass downwardly and are connected with the latches as before described. Other cables 28 are connected with the ends of the bar 26 but pass in an opposite direction to the cables 27 and are connected with the latches on the other side of the bar 13'.

It will thus be seen that as soon as the vertical rod 20 comes against the post 21 on the movement of the car to dumping position the doors will be opened simultaneously to dump the load. Then when the car is moved from the dumping location all the doors will be closed by the inclined post 2i.

It is thought from the foregoing description'that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make such changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

Vhat I claim is 1. In combination with a dumping car having a plurality of chutes in its bottom, of a pair of doors for closing each chute. latch means for said doors, arms connecting each pair of doors together for causing them to move in unison, a rod carried by the bottom of the car, means located under the car and including flexible elements for connecting said rod with the latch means to cause said doors to be opened when the rod is partially rotated and an obstruction along the track for engaging saidrod to give the same a partial rotation.

52. In combination with a dumping car having 'a plurality of chutes in its bottom, of a pair of doors for closing each chute. arms connecting each pair of doors together. a latch carried by one door and engaging with the other door, a rod carried by the car. pulleys also carried by the car, a pair of cables connecting each latch with the rod and so arranged in respect to the said rod and pulleys that the latch will be moved into inoperative position on the movement. of the rod in either direction and means for oscillating said rod.

3. In combination with a dumping car. having a plurality of chutes in its bottom, of a pair of doors for closing each chute, an oscillating rod carried by the car bottom, means operable by the said rod for opening all the doors simultaneously, a bar pivoted to the end of said rod and adapted to engage an obstruction along the track and spring means for holding said bar in either its raised orlowered position.

In testimony whereof I aflix my signature.

TOBIAS CHNAPKO.
