DUMP CAR.
Application filed April 2,
This invention relates to dump cars, and more particularly to cars of this character which are used in the mining industry for transporting coal, ore, etc, and has for its object to provide in a manner as hereinafter set forth A dump car wherein the doors which. constitute the floor of the car, will be automatically released for the purpose of discharging the cargo, after which said doors will be automatically closed and latched.
Further objects of the invention are to provide in a manner as hereinafter set forth, a dump ear of the aforementioned. character which is simple in construction, eilicient in its use strong, durable, and. which may be manufactured at low cost.
In the drawings which illustrate this invention- Figure 1 is a side elevation of the dump car in accordance with this invention.
Figure 2 is a like viewlooking towards the opposite side of the ear.
Figure 3 is an end elevation showing the doors closed.
Figure 4 is a plan view.
Figure 5 is a longitudinal sectional view on the line 5-5 of Figure 4.
Figure 6 is a transverse sectional view taken on the line 66 of Figure 4, and.
Figure 7 is a detail view, partly in section, of the door latching mechanism.
Referring to the drawings in detail, the reference character 1 designates generally the body of the car and comprises; a pair of vertical side walls 2 having outwardly flared top portions The side walls are connected at their opposite ends by vertical end walls 4. The body 1 is provided with a supporting frame comprising a pair of side beams 5 connected at their opposite ends by the end beams 6. The supporting frame entirely surrounds the lower portion of the body.
The bottom, or floor of the body, is formed of a pair of longitudinally extending doors 7. hingedly secured at the outer edges thereof to the side beams 5 of theframe. The doors 7 are of such width and length that the inner edges thereof will overlap each other, and the ends of said doors will. extend across the lower sides of the end beams (3.
The doors 7 are stiffened and. strengthened a. pair of longitiiidinal strips 8 of angle iron, which extend the entire length of the doors near the inner edges thereof, It will thus be seen that the doors 7, when open, will 1928. Serial N5. 266,661.
form a chute by means of which the material being unloaded will be directed between the car rails, and with the doors forming a shield to prevent the rails from becoming obstrut-ted.
The doors 7 are held in closed position by oppositely disposed pairs of links 9, pivotally secured at their lower ends to said doors near the inner edges of, and at a point near the opposite ends thereof. The links 9 have their upper ends pivotally connected to the pivot bolts 10, carried by apair of slidable bars 11, which are mounted in. vertically disposed. guide casings 12 having open ends. The casings 12 are mounted centrally on the inner sides of the end walls 4; of the body. The casings 12 are provided with vertical slots 13 on the inner sides thereof for the movement of the pivot bolts 10.
The slidable bars 11 are provided on the outer sides thereof, with a series of notches 14-, :nlaptedto coact with a pair of latches 15 mounted on the outer sides of the end beams 6. The end walls 4 of the body are provided with openings 16 for the passage of the latches therethrough for engagement with the notched sides of the bars 11.
A pair of leaf springs 17 are secured at one end to the outer faces of the end beams (i by the fastening elements 18, the free ends of saidv springs engaging the outer sides of the latches 15 for the purpose of forcing same inwardly into engagement with the bars ll. The springslT are kept under tension by the retaining straps 19 which flex the central. portions of said springs inwardly, as will be apparent from a study of the drawings.
A pair of actuating rods 20 having broad flat inner end portions 21 interposed be tween. the upper portions of the latches 15 and the end beams (S are rotatably mounted on said. end beams. The outer ends of the rods 20 project outwardly beyond the side walls of the car body 1 and terminate in dowmvardly turned end portions 22. The mrtions 22 are pivotally connected. at the lower ends thereof, to the opposite ends of an upwardly bowed longitudinally extending transmission rod 23.
The body 1 is mounted upon a pair of axles 24, which pass trz uisversely theretln'ough. at a point :intermediate the upper and. lower ends of the vertical side we 5 lilhr s through il l beams for the axles 24. The opposite ends of the axles project outwardly from the bearing boxes 25 and have secured thereon the wheels 26. It will thus be seen that, by reason of theaxles passing through the body instead of beneath same, said body can be built much deeper, with a corresponding increase in capacity without increasing 'the height thereof.
A closing mechanism is provided for the doors 7 and comprises a shaft 27 which extends transversely through the body 1 above said doors, and journaled in the side beams 5. One end of the shaft 27 projects outwardly beyond the side of the car and has secured thereto the curved actuating lever 28. Centrally of the car body, the shaft 27 is provided with a crank portion 29 to which one end of a pair of chains 30 is attached, the opposite ends of each of said chains being secured to one of the doors 7.
A trip member 31 is positioned adjacent one side of the track rails 32 in such manner that same will engage the down turned portion 22 of the rods 20 when the .car reaches that point. Adjacent the opposite side of the track, a trip 33, adapted to engage the lever 28, is mounted.
The operation of my dump car is as follows:
When the car reaches the point where it is desired to discharge the contents thereof, the portion 22 of one of the actuating rods 20 engages the trip 31 and is swung rearwardl'y, thereby rotating said rod. Correspending motion is transmitted to the actuating rod on the opposite end of the car by the bowed rod 23. When the rods 20 are retated, similar movement is imparted to the flattened end portions 21 thereof with the result that the latches 15 are shifted outwardly against the springs 17, thereby releasing the notched bars 11, as clearly shown in Figure 7. The bars 11 having been released, the doors 7 will then open downwardly and discharge the contents of the car between the track rails. Any tendency of the doors to remain closed will be overcome by the weight of said contents. When the pivot bolt 10 engages the lower end wall of the slot 13, it will serve as a stop to limit the downward swing of the doors.
As the car continues along the track, the upturned end of the lever 28 strikes the trip 33 forcing said lever downwardly and imparting-a rotary movement to the shaft 27 which rocks the crank portion 29 of said shaft upwardly. By means of the connecting chains 30 the doors 7 will be drawn upwardly, into the closed position. The upward movement of the doors elevates the notched bars 11 in the casings 12 by means of the links 9. The notches 14 on the bars 11 are of such shape that the latches 15 will ride over same during the upward movement of said bars, but will prevent any downward movement of sand bars unless the latches are withdrawn by the actuating rods 20.
It is thought that the many advantages of claims.
What I claimis:
1. A dump car comprising a body provided with supporting wheels, hinged doors forming the floor of said body, casings mounted on said body, slidable bars posi tioned in said casings and connected to said doors, shiftable latches carried by the car and adapted to co-act with said bars to re tain the doors in raised position, and means for shifting said latches toward or away from said bars to latch andrelease said doors.
