Application filed June 21, 1919. Serial No. 305,727.

To allfiwhom it may concern: 7

Be it known that 1, JAMES W. HURT, a citizen of the United States, residingat York, R. F. D. #7, in the county of Seward and State of Nebraska, have invented new and useful Improvements in Grain-Elevators, of which the following is a specification. 7

My present invent-ion pertains to elevators, for hay, grain and the like, and it contemplates the provision in a device of the character set forth of means whereby hay, grain, etc., may be elevated into a barn and stacked in a neat pile, and this with but a small amount of effort and labor.

The invention will be fully understood from the following description and claims when the same are read in connection, with the drawings, accompanying and forming part of this specification, in which:

Figure-1 is a top plan view of my device showing the rakes in their open position and further showing one of the conveyers in raised position.

Fig. 2 is a side elevation of the device.

Fig. 3 is a front elevation showing the main frame and elevator resting on the cross-piece that is raised and lowered on the upstanding posts of the main frame.

Fig. i is a view showing the working of the rakes and the horizontally-movable conveyer resting between the rakesto receive the grain or hay from said rakes. V

Fig. 5 is a detail view of the main elevator and horizontally-movable conveyer.

Fig. 6 is a detail view of the means I employ to secure the movable elevator so that.

the same may be placed at various positions with respect to the cross-arms of the mainframe. p

Similar numerals of reference designate corresponding parts in all of the views of the drawings. 1

My noveldevice comprises a frame of ladder construction having the forwardly reaching stiles 1 and at the forward end thereof said stiles are secured to a cross piece 2 (Fig. 3) said cross piece 2 being provided at each end thereof with an upstanding post or member 3. v v

Near the upper end of each post 3 1 pro vide pulleys 6 and around these pulleys I pass a cable 8 that is provided at one end with a weight that is secured to the crosspiece 4; that extends from one to the other of the posts 3 at the point 7 and is movable in the slots 9 of said posts. Thus the weight will assist in the lowering of the member l.

At its base, the device is supported on a frame 10 to which is secured a traveling endless conveyer 1-1; and said conveyer has teeth 12, that by preference are pitched back- Wardly and said teeth are further provided on alternate cross brace members 13 that go to make up the conveyer. For the purpose of im artin motion to this conve er, I

provide the cross-pieces other than those just alluded to and designated by 1 with.

teeth of the sprocket form that engage the chains 16 that derive motion from sprocket wheels 17 that are provided at each end of.

The teeth of the cross bracesthe conveyor. 13, it will be seen are for the purpose of retaining and catching hay, grain or other feed that is thrown on the conveyer. At this point, I would distinctly have itundcrstood that the sprocket wheel 17 may be operated manually or by power of an internal cornbastion engine or other agency, orderto drive the conveyer 11. 7

As clearly'shown in Fig. 2, the said sprockets may be. secured to upstanding posts 18, 7

that I provident, each end of the main frame or support 10, and said posts have pulleys19 secured to the upper end of the.

said posts and cables 20 that are passed through'the pulleys and hang downwardly for a purpose that will be apparent asl detail the description ofthe device.

As clearly appears in Fig. '1, rods 21 are secured at their ends to posts 18 andextend from one to the other of said posts, and it will also be seen by reference to'the said figure of the drawings, that the novel rakes 22 of my device are pivoted to said rods.

These rakes normally rest on'the ground,

but in order to elevate the rakes when occasion demands, the cables 20 are attached to the lower-most part of the rakes; ihe opposite end of tho-cables 20 are free as shown. The said rakes 22 as before'stated are secured in hinged mannerfon the rods 2l'and comprise a member or short armQe' that is secured bya pin 25 to the rakes 22.

. It Wlll be gathered from the foregoing that when the rakes are in theiropen or normal positions, as shown in Fig. i, by full lines, they are ready for reception of hay, grain and the like. After the rakes have been filled with grain, the cable 20 is pulled vator 30 comprisestheteeth 31 that extend;

downwardly, andthrough this medium, the

rakes will be elevated and the grain will consequently'be forced onto the conveyor 11.

At a point at the inner traverse of the 0011- veyer 11 and arranged to receive grain from;

said conveyer 11, is my novel table elevator 30, and similar to the conveyer 11, the said elestraight up from their'cross brace members; the chain 32 and the sprockets 38, all of Y Which elements operate similar to the cor- -slot 38 of plate fid, 'Naturally the'limiting; of-movement ofarinA-O will limit movement from right to l eft o-f the elevator.

responding elements of the conveyer '11" in order to cause the endless belt of the elevator to travel upwardly to elevate the hay or grain. a i

This elevator 30 is provided at its lower-q most endand adjacent the support 10, With secured to a cross piece 34 also fastened to the stiles,

a plate 30 that is that rests and is l of the main frame; The preferred manner I desire to secure this plate 30" and member 34. is through a bolt 35 and nut 36, respectively, the bolt being capable of rotation on the member 34 so as to permit the plate 30" to rotate thereon. At {a point in-the rear of the plate 30' there is a semi-circular opening and on the cross member 34 I provide a tooth orprojection 37 that rests in said semi; circular opening of the plate 30 and permits the plate to swin the distance of said open- ;In order to permit movement" of the elevator 30, thearm 40 is provided at its end with a portion having an axle 41 and to Which the sprocket, Wheel 33 is secured.

The arm 40 issecured to axle 4-1 at its up perend,and said arm extends downwardly plate 34. The as an axis for j and rests on the member or By reference to Fig. 2, itwillbe'seen that the elevatorBO isprovided. near its upper end and on each side thereof Witlr'a roller and teeth 31 beinghe'ld slightly above the cross member 4, when it is desired to swing-the table elevator horizontally on said cross-member l.

Inthepractical use of the device, the elevator 30 which [under normal conditions rests on the stiles 1, may be elevated by an operator pulling onthe cable 8. Thi's vrvill raise theelevator 30 and cross member 4-.

Because of the movement of the elevator on the cross member 4;,"the grain will be stacked in a neat pile. It is to be understood that the crossancmbers are retained in a certain position above the main frame or stiles 1 by tying the cables'S toa stake or other element on the ground.

It will be gathered from the foregoing.

that the device is simple in construction and capable of being cheaply manufactured and because of its construction comprises no delic ate parts such as are likely to become worn out after a short period of use, and furthermore because of its construction the device may be operated by a single person.
