GRAIN `ELEVATOR AND DUMP.
SPECIFICATION forming pari'. of `Letters Patent No. 665,216, dated January 1, 1901. Application filed June 28, 1900.4 Serial No. 21,924. tNo model.)
T0 all whom it may concern,.-
Be it known that I, SCOTT HAR'rsocK, a citizen of. the United States, residing at Henry, in the county of Marshall and State of Illinois, have invented a new and useful Grain Elevator and Dump, of which the following is a specification.
My invention is an improved grain dump and elevator adapted for use in unloading grain from wagons and elevating the same, particularly in places at which the amount of work to be done will not warrant' the use of a steam-engine or other costly power plant for operating the elevator.
My invention consists in the peculiar construction and combination of devices hereinafter fully set forth, and pointed out in the claims.
In the accompanying drawings, Figure l is a side elevation of a grain dump and elevator constructed in accordance with my invention. Fig. 2 is a vertical longitudinal sectional view of the same. View of the same. Fig. 4 is a sectional view taken on the line a a. of Fig. 3. Fig.l 5 is a detail sectional view of the elevator. Fig. 6 is a detail sectional view of thedump mechanism, taken on the line b b of Fig. 3. is a similar view taken on the line c c of Fig. 3. Figs. 8 and 9 are detail views of Amembers of the endless elevator. Y l
The dump-platform A is supported by a frame 2, which is mounted on supportingwheels 3, the whole constituting a truck. A transversely-disposed trough 4 is near one end of the platform, which I will call the front end thereof. In the said trough is a horizontally-disposed conveyer 5, comprising an endless traveling element 6, which -is .made up of endless belts or chains 7 and transverselydisposed sections 8, which connect said endless belts or chains, and driving and supporting rollers 9 10, on which the endless traveling element operates inthe direction shown by the arrows in Fig. 4 to convey grain which is dumped thereon tov the'elevator B at one side of the platform. The roller 9 `has an extended shaft 11, which is provided at its front end with a power-pulley 12, driven from a power-pulley 13 on a shaft 14 by an endless belt 15. The said shaft 14 is journaled in bearings 16 on the outer side of the frame of the Fig. 3 is a top plan Fig. 7
elevator at the base thereof, and said shaft at its rear end is provided with a miter gearwheel17. The elevator is of the endless travel` ing type and has the usual inclined trunk or casing' 18, and the endless traveling element 19 of the elevator is disposed in the said trunk or casing and supported and actuated by rollers 2021. The latter, which is at the lower end of the trunk or casing, has an extended shaft 22, provided with a miter-gear 23, that engages miter-gear 17 ,and said shaftis further provided with a power-pulley 24.
It will be understood from the foregoing description and by reference to the drawings that the conveyer and elevator are operated in unison, the conveyer serving to carry the grain to the lower end of the elevator trunk or casing and the endless traveling element of the elevator serving to elevate the grain.
The endless traveling element of the elevator is composed of bucket-sections 25, each of which has a right-angled ledge 26 on one side, and the inner sides of said buckets, at the edges thereof, are curved, as at-27. The said bucket-sections are connected together in series by flexible cords 28. In passing `over a Vroller at the upper or lower end of the elevator-trunk the fiexible connecting-cords 28 adapt the bucket-sections to change theirl positions relatively to conform to the shape of the rollers,and the curved edges 27 of the respective bucket-sections coact as the bucketsections pass around the said rollers, the said curved edges 27 enabling the bucket-sections to remain in contact with each other at all times, even when changing the direction of their movement. ,Hence the endless traveling elevating element is adapted to discharge all the grain elevated thereby `through the spout 29 ofthe trunk or casing 18 without dropping any ofthe grain between the bucketsections which are disposed and in the act of passing on the upper roller 20.
The conveyer 5 is adapted to be closed by a trap-30 on the upper side of the'trough 4, the 'said trap being hinged at one side on a rock-shaft'3l. Said rock-shaft is provided on the side of the platform opposite the elevator with a rock-arm 32. 7A hand-lever 33 is disposed on one side of the platform and fulcrumed to the frame thereof at its lowe'r end, as at 34. A pitman 35 connects'the said IOO hand-lever with the rockarm 32, and it will be understood that the trap-door 30 may be operated by the lever33 in such manner as to cover or uncover the conveyer 5, as may be required. A segment-plate 36 on one side of the platform coactswith a spring-pressed dog 37 of the usual form, with which the handlever 33 is provided, to secure the latter at any desired position.
In longitudinally-disposed openings 38 in the sides of the platform are dump-bars 39, the latter having centrally-disposed pivotal supports 40, whereby the said dump-bars are adapted to be disposed in the same plane with the platform or to be inclined to the position indicated in Figs. 2 and 6 of the drawings for the purpose of lowering the rear end of a wagon on the platform, the hind wheels of which are on the front ends of the dum p-bars, in such manner as to incline the wagon-bed to such an extent as to cause the same to discharge the load of grain therefrom by gravity into the trough 4 and onto the conveyer 5. The platform is provided on its front end with a skid 4l,forming an inclined frame, up which the wagon may be driven, so as to dispose the same on the platform with its rear Wheels resting on the front portions of the dumpbars. While the wagon is being thus disposed on the platform, the dump-bars are in a horizontal position and supported in such position by eccentrics 42 on ashaft 43, which is journaled in bearings 44, secured to the under sides ofthe dump-bars at a suitable distance from the front ends thereof. The said shaft 43 is a rock-shaft and is provided at one end with a rock-arm 45, which is connected by a pitman 46 to a hand-lever 47. Said hand-lever is in all respects similar to the lever 33, and it will be understood that by means of said hand-lever, said pitman, and said rock-arm the rock-shaft may be partly turned in either direction and caused to impart partial rotary motion to the eccentrics 42, whereby the front ends of the dump-bars may be lowered to the position shown in Figs. 2 and 6, so as to dump the load from the wagon. The eccentrics 42 are supported and operate upon suitable side bars 48, which form a portion of the frame that supports the platform.
I will now describe my improved treadpower C, which is operated by the team that draws the wagon and furnishes power to operate the endless conveyer 5 and the elevator B. A frame 49 of suitable construction sup- A ports the tread-power and is provided with supporting wheels or rollers 50, whereby it is converted into a truck which may be readily drawn from place to place. The frame 5l carries the endless tread-apron 52, which operates on rollers 53 54 at the inner and outer end of frame 52. The said frame 52 is pivotally mounted at its inner end between vertical standards 55, which rise from the inner end of truck-frame 49. A rock-shaft 56 is journaled in the outer or rear end of frame 52, and keyed to said shaft are eccentrics 57, which operate on the frame 49, support the rear end of the frame 52, and may be turned by the rock-shaft 56 to raise the tread-power to the inclined position (shown in Fig. 2) or to lower the same to the horizontal position. (Shown in Fig. l.) The rock-shaft 56 may be thus turned by a pitman 58, which is connected to one of the eccentrics, as at 59, and is operated by a hand-lever 60, which is fulcrumed on one of the standards 55 and is locked in the required position by a coacting segment-plate 6l and dog 62. p
A combined skid and gate 63 is hinged to the rear side of the tread-power frame and when turned up to the position shown in Fig. 2 forms a gate or bar to stop the team attached to the wagon which is to be unladen, and when turned downward to the position indicated in Figs. l and 3 of the drawings forms an inclined plane to facilitate the pas sage of the wagon from the tread-power. The said combined skid and gate is operative by a pitman 64 and hand-lever 65, the latter having a dog 66, which coacts with a segmentplate 67 to secure the gate in the position shown in Fig. 2.
I will now describe means for transmitting power from the tread-power to the endless conveyerandelevator. Apower-roller68has its shaft journaled in bearings in theframe 62, and said power-roller is disposed about midway between the rollers 53 54 and is engaged by the upper and lower leads of the tread-apron and rotated by frictional contact therewith. The shaft 69 of power-roller 68 is extended at one end and provided with a power-pulley 70, which is connected to the power-pulley 24 on shaft 22 by an endless power-belt 71 when the platform-frame and tread-bar frame are secured together end to end, as shown herein. Hooks 72 or other suitable devices may be employed for thus securing the said frames together. The shaft 69 is provided also with a friction-pulley 69, which is adapted to be engaged by a frictionbar 73 to stop the tread-power when it is desired to discontinue the operation thereof and of the conveyer and elevator. A suitable hand-lever 74 is employed, which is mounted on the frame 49 and is connected to the friction-bar 73 by a pitman 75, the function of this hand-lever and said pitman being to operate the said friction-bar, as will be linderstood.
Having thus described my invention, I claiml. A grain dump or elevator having a platform onto which a wagon may be driven, an elevator, a conveyer to discharge the load from the wagon to said elevator, in combination with a horse-power at one end of the platform, adapted to be operated by the horse or horses attached to the wagon, connections between said horse-power and elevator, whereby the latter may be driven, said connections including a shaft rotated by the horsepower, a

is provided, an operating-lever and connections between the same `amd said shaft, substantially as described.
In testimony that I claim the foregoing as r 5 my own I have hereto affixed my signature in the presence of two witnesses.
