. UNLOADING DEVICE.

Application filed October 21,1920. Serial No. 418,556.

To all whom it may concern:

Be it known that I, GUY O. BAKER, a citizen of the United States, and resident of Atlantic, in the county of Cass and State of Iowa, have invented a certain new and useful Unloading Device, of which the following is a specification.

The object of my invention is to provide a device of simple, durable and inexpensive construction, for quickly and efficiently unloading-gravel and the like from gondola cars, which device may be easily and quickly placed in operative position relative to the said car. I

A further object is to provide in a device for unloading gravel and the like from gondola cars, an improved derrick which is of light construction and may be quickly and easily placed in operative position. i

A further object is to provide inan unloading device for gondola cars and the like, an improved delivery chute adapted to be quickly attached and detached, and also capable of being adjusted to meet the various working conditions to which devices of this class are subjected, and furthercapable of being quickly and easily folded to. permit wagons and the like to be moved to filling position.

Still a further object isto provide an unloading device employing a drag shovel or scoop, and improved means for hitching and handling said scoop. 1

My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 is a transverse sectional view of a portion of a gondola car showing myimproved loading device attached in sideelevation.

Figureo is a detail view showing the brace member for my improved delivery chute.

1n the drawings 1 have shown my device attached to the body portion of a gondola car 10, although it may be usedin other ways.

The device comprises an A shaped frame member 11, havinga horizontal bar 12 and a plate 13. The-plate 13 is riveted to the members 11 near the apex of the frame, and the bar 12 is riveted at a point near the lower end of the members 11. The lower end of each of the members 11 is provided with a (lamp 1 1, having a setscrew 15. Each set screw 15 is provided. with a head 16 having an opening 17, which is for the purpose of receiving a bar by which the set screw may be rotated. to be placed over the upper edge of the car body 10, and when so placed the A-frame .11 will rest in a perpendicular position.

For supporting the upper end of the frame 11 against lateral movement, I have provided a brace member having a wing 19 at its upper end, which is designed to rest on top of the plate 20, the said plate being secured to the upper ends of the members 11, as illustrated in Figure The wing 19 is secured in position by means of a pin 21. The lower endof the member 18 has a clamp 22 similar to the clamp 1 1, with the exception that it is secured by means of a single bolt 23. This bolt provides a pivotal movement between the clamp and the bar 18. The bar 18 is provided with a series ot openings 24, by means of which the clamp 22 may be adjusted so that the bar 18 may be adapted to fit cars of different widths. The clamp 22 is provided, with a set screw similar to the set screw 15, and is designed to be secured to the upper edge of the car 10 on the opposite side from which the member 11 is secured.

Bythis arrangement it will be seen that I have provided a derrick of simple construction and of light weight, which may be easily attached to the car body and placed in position.

Pivotally secured to the member 18, near its top end, is what I shall term a hitch bar 25, which is provided with a series of openings 26. The free end of this hitch bar is designed to be passed through an opening 27 the plate 13.. i

The clamps 1a! are designed 60, bers 51-.

end of a cable 28, which is detachably connected thereto by means of a hook 29 and a pulley 30 having a hook member 31. The cable .28 is provided with a movable block 32, and has its free end extended through the pulley, which is hitched in the bar 25 near the plate 13, then extended down wardly to a pulley 33 which may be staked to the ground or tied to the rail on which thecarismounted." The free end of the cable is provided with a singletree 34, to which a draft animal may be'hitched.

' The pulley 32 is designed to carry a scoop 36, whichishitched thereto by means of chain members 36 and 37. The chain members 36 arehitched near the forward end of the scoop and to a ring 38. The chain 37 has: one end hitched to the loop 38, while the other is designed to be attached to the lrear end of theysfcoop by means of a hook39.

This-hook 39;and"chain 37 provide: means whereby the angle of the scoop 35 may be variedrelative to the angle of the cable 23 when in an operative position. The scoop 35 is provided with handles 40, which are secured to the back thereof by means of straps 41 extending beneath the bottom at eachside of the scoop, and terminating at a point where the chains 36 are attached. A

transverse member 42 is provided on the under side of the scoop 35, and has each end terminating with the pivot of the chains 36.

j Thus it willbe seenthat I have provided a very rigid scoop, with reinforcing memfbers at the .points where the greatest strain is applied to the scoop. By this arrangement it will be seen that the body member may be made of very light material without sacrificing the strength of the scoop.

I, For delivering the material, I have provided a chute 43 having diverging side 11131111361844. Thisrscoop is designed to be placedadjacent to the outside of the car in member 12 of the frame 11 by means of hinged-hook members 45. Each of the hook ,members lo is designed to be placed in a slot r-ltlwin the member 12, thus providing means f0r easily and quickly detaching the chute member.

.For supporting-the outer'end of the chute I have provided horizontal brace members 4.7.which area-formed tubular and designed toftelescopically receive a U-shaped member 48;, the member 48 being secured in position by means-of set screws 49. The braces 41.7

are secured to the chute 43 by meansof pivots oQ mounted in the bracket .mem

45 an. inclined position, and is attached to the,

7 When the chute lil is. placed position the mem.ber .l 8 .is designed to..rest against qthesi le 9 einnv h e me in a" horizontal position. The angle of the a; chute may be varied by adjuSting-"themember 48 in the members 47, while the side member 48 is held against downward movement by means of chains52,each of which is adjustably connected to the upper ends of the side members of the chute by means of hooks 53.

It often happens in driving a wagon into position beneath the delivery end of the chute, that it is necessary to drop the chute out of the way, and this may be easily and quickly done by merely elevating the free end of the member-d8. This will permit the free end of the chute to swing downwardly and rest in a substantially vertical position, as shown by dotted lines in Figure 1. lVhen the wagon is in position the chute may be quickly moved intopositionby dropping the member 48. v a i As, the angle of the chute is varied by ad justing the members 47 and 48, the length of the chain 52 will also have to be adjusted in'order to-keep the said membersin a horizontal position. v This iseas ily and quickly done, as before described, by means of the hooks 53; I

as follows: Assuming that the cable 28 has been hooked to the bar 25, and the pulley 30 placed in position near the plate 31, and that the movableblock 32 and the scraper 35 are in position, and that the scoop is in the position shown-in dotted lines in Figure 1. the operator will grasp the handles 40 and draw the scoop backward or outward to the opposite side of the car, after which the chain 37 is adjusted on the hook 39 to give thescoop the proper angle. The draft animal is then started and the scoop drawn radially toward a point beneath the bar 25. After the scoop has reachedthe saidpoint, a further movement of the draft animal will cause the scoop to be elevated vertically. and'ifthe angle of thechain 37 has been properly. adjusted the scoop 35 will assume a position as indicated by dotted lines). After the scoop is in the said position, the draft animal is allowed to back up slightly. while the operator elevates the handles 40, causing the forward end of the scoop to be tilted downwardly and into the chute 43. The scoop is then returned to filling position.

.111 operating this device. however. it should .be noted that the operator should commeni'c at the far'side'or corners and draw the material inwardly radially to a point below the bar '25. By this method the opposite sides and'each end of the carwill be eicarated first. which will'provide an incline from which the shovel may be fillcd. This is clearly illustrated in both Figures 1 and '3.As' the angle of theincline varies, the length offthe chain 37 will havefto be slightly adjusted to meet the requirements o'fthe different angles." l I j 1 l Another important feature inoperating ready to be,

. :9 The practical" operation of-the deviceis this device is to get the scoop in the right position for easily discharging into the chute. This is accomplished by the proper placing of the cable 28 on the pulley 30 on the hitch bar 25.

Sometimes it is desired to fill a car, rather than empty it, in which case the hook 29 of the cable 28 may be placed in one of the openings in the extreme end of the hitch bar 25, while the pulley 30 may be placed on the opposite side of the plate 13 from that shown inFigure 1.

One important thing in a device of this kind isto be able to easily and quickly attach the device to the car. It-has been demonstrated by actual practice that a large car may be entirely emptied of material in sixty minutes. For that reasonit is very essential that the derrick be taken down and placed in position in a very short length of time, as otherwise the time for setting up the device would be greater than the time required to empty the car.

In this connection it will be seen that the chute may be easily detached by simply liftin g it upwardly, which will'cause the hooks 45 to disengage the member 12, the members 47 and 48 folding against. the bottom of the chute. The derrick may be quickly removed by simply releasing the three set screws and removing the pin 29.
