' In the accompanying drawings thepreferred form; of the invention has been shown.
In said drawings Figure 1 is a :side elevation of a portion of a. dump Pi and showings car passing. thercover with the bottom heldin load retaining position Figure .2 is a top p-l'an view of the structure shown; in Figure ls Y o V Figure 3 is. a centr qvertical longitudinal section through the car and the track on which it is mounted while approaching the dump pit.
Figure 4 is an end elevation of the car, a portion being broken away.
Figure 5 is an enlarged section on line 5--5, Figure 1.
Figure 6 is an enlarged section on line 66, Figure 1.
Figure 7 is an enlarged central vertical longitudinal section through the car and a portion *td closed: position following the dumping of; a load.
Referring? to the figures by characters. of ref eren'ce ldesi'gnates a pit in the form of a hopper which is located in a gap formed between spaced-track. sections 2' and: 3.. The to" be. unloaded: are adapted to approach the. pit; along the section 2 and, afiter being unloaded, move onto the section it, The sides at thedump pit extend above the. level of the thacksections to form guidesas shown at. 4 spaced apart a. distance: slightly greater than the-width .of thecar frame hereinafter described and while the bottom of: dump pit isformed: of downwardly converging portions 5 and 6,. the portion 65 inclined upwardly toward. the end" of the track section 5 so as to form. a wheel guide as hereinatterexplained.
Secured. to the: inner surfaces oi the side portions- 4 are bodysupporting rails I and inv each of these railsis jcuma-lled a longitudinally extending series of spaced: rollers 8-. These rollers are so located as to engage and. support thebottom suriace of the side: portions of a car frame while a car is passingiover the dump pit as hereinafter explained.
The car to be used with the: dump pit thus far described is 0t special construction so as to permit use: in handling: a maximum load: of coal 'taken-v from. a low vein. The car" comprises a body frame 9 the width of which is slightly less than the distance between'the sides 4 of the dump pit and upstanding from -the inner sides ofthis firame-aretheside-andend walls H!" of the car body, these walls, in the structure! shown,
being, fixedly joined to the frame 9:. Secured to and extending outwardly fromthe central part ofeach end. of the frame is a coupling head Hi and II. respectively and connected to and ex- 40 tending backwardly from the front. coupling head II is a tongue t2 having an. upward-1y extended angularlug: 1:3. Extending forwardly from the near coupling head; lit is' another tongue 1-4' having a downwardly" extended angular lug I55.
. A- trar'isverse axle i6; is mounted in the sides oi frame 9' adjacent to the forward endsthereof and supported by wheeis H. A bottom for-the car body has been indicated. at 8 and is. extended-L under the axle is by means of blocks I9 through which the axle extends. A shield 20 is arched over the axle and is joined to the bottom [8, this shield being extended from one side to the other of the car body and formed with enlargements or guards 2| which of the pit and showing the bottom of the car house the upper portions of the wheels l1 so that rotation of the wheels will not be interfered with by bulk material contained within the car.
Another axle 22 is mounted in bearing blocks 23 on the bottom l8 near the other end thereof and this axle is supported by wheels 24. It will be noted that this axle 22 is not connected to the frame 9 but is joined solely to the bottom l8. It will also be noted that the bottom 18 is cut-away to. permit the wheels I! and 24 to extend therethrough, theopeningspro: vided for these wheels being indicated at 25 and being completely covered by the shield 23 and by another shield 26 which is mounted on the bottom and bridges axle 22 and the wheels 24.
As axle I6 is spaced inwardly from theends of the bottom I8 but is nearer the front'head in than the rear head II, it constitutesa pivotal' support for the bottom which obviously is over balanced and tends to swing downwardly'at its rear end. Both ends of the bottom have apertures 21 and when the bottom I8 is in closed position, the .forward end thereof overlies the tongue 12 while the rear end of the bottom extends. under and bears upwardly against the other or rear tongue M. Whenthebottom is in closed position the lug l3 projectsinto the forward opening 21 while the lug l 'extendsinto the rear opening 21. 4 Thus when a pull isltransmitted to'the forward coupling head. ID the bottom will serve to transmit the power from the lug I3 tothe lug l5 and thence through "tongue [4 to the-rear coupling head II. For the purpose of reenforcing the bottom it is preferred to extend a bar 28 along bottom l8 to. which it is secured, this bar having openings 29 which register with the.open-. ings 21 so as to receive the lugs l3 and .15.
The rear portion of the bottom 18 has an extension 30 adapted to extend under the rear portion of frame 9 so that when the wheels I! and 24 are mounted on the rails of a track; the axle l6 and the extension'3ll will cooperate to support frame 9 and the-upstanding end and side walls l0 as shown for example in Figure 3.
Pivotally mounted on the rear end of the caris a latch 3| which extends downwardly through openings 32 in the head II and also through a slot 33 in the extension 30 wherebythe-head 34 of the latch will engage under the-extension 30 and hold it in raised position a'gainst the'bdt tom of frame 9. Thislever has a laterally extending arm 35 which projectsslightly-beyond oneside ofthecarr- M Mounted on the dump pitat one side thereof and adjacent to the'track section 2 is a lever 36 having an actuating arm- 31- which canbe' operatedby means of a rope'38 extending to any point most convenient tothe operator. One-end of lever 35 projects above the side of the dump pit and carries a cam plate '39 which, as shown by full lines in Figure 1,is normally positioned in the path of the endof the tripping lever orarm 35. Lever 36 is. so. proportioned, however; that when it is shifted in one direction out of normal position, as shown by broken lines .in Figure 1, the cam plate 39 will be raised above the path of the tripping arm or lever 35 so that the same can pass thereunder without releasing the extension 30 from engagement with the head 34 of latch 3|.
' gage the'latch from the extension 30.
Normally the cam plate 39 is positioned as shown in Figure 1 and the loaded car is propelled along the track sections 2 in any suitable manner, as by means of a cable 40. As the body of the car is very low, the bottom being below the axles, said car is especially adapted for handling low vein coal. As the car travels along track section 2 with the wheels I! and 24 travelling along the rails, the body of the car will be supported as shown in Figure 3 by axle .l6 and extension 30.
As the car enters the dump pit; the sides of the frame 9 will be brought to position over the series of rollers 8 and after all parts of the car are located between the track sections and above the pit, the tripping arm 35 will come against and ride upwardly along the cam plate 39 so as to disen- As the 5 bottom is thus relieved of its rear support, it will swing downwardly, as shown for example, in Figure 7, thereby dumping the contents of the car into the .pit," Asthecar continues to advance, its body being supported by the series of rollers 8, the. wheels connected to the bottom I8 will ultimately come against the guide or bottom portion 6 and will ride. upwardly therealong, as shown in.Figure .7,.until the wheels are finally restored to the'itracks forming section 3 and when this position is assumed, the extension automatically engages the .latch 3| so that the parts. are all restored totheir initial positions.
Obviously several. cars could be coupled together bymeans ofvlinks' or'the like in engagement with the coupling heads and as the train of cars passes over the dump pit the said cars will be successively dumped and reset. Should it be desir'ed'to move acanacrossthe pit without causing the bottomto swing downwardly, it would merel-y benecessary to elevate the cam plate as shown by broken lines in Figure 1 so that the tripping arm'35 will pass underv the said plate without being'actuatedthereby. r In addition to extension 30 the tongues l2 and 14 also serve to limit the swinging movement of the bottom relative to thebody.
1 -What is claimed is: The combination with spaced alined track sections providing a gap therebetween, of a car bottom movablealong the sections and across the gap,:spaced pairs of track wheels connected to-the bottom, a car-frame supported by the bottom, saidbottom being movable relative to the frame about the axialcenter of the wheels of one pair, laterally spaced means bridging the gap and positioned for supporting the respective sides of the frame and guiding the wheels against lateral displacement-relative to the track sections while the bottom is above thegap, thewheels of the other pair constituting means for releasing the bottom for abrupt'downward swinging away from the fr'ar'ne' when said wheels leave one track section,*thereby-to be suspended by the bottom in the gap, and a guide below;the gap and inclined upwardly to one of the sections for engagernent by and elevation of the suspended 1S I l a i 1 WILLIE H.
