IMPROVEMENT IN HAY AND GRAIN ELEVATORS.

Specification forming part of Letters Patent No. 152,760, dated July 7, 1874; application filed May 15, 1874.

To all whom it may concern:

Be it known that I, DAVID MOREY, of Watsonville, Santa Cruz county, State of California, have invented an Improved Hay and Grain Elevator; and I do hereby declare the following description and accompanying drawings are suflicient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvement without further invention or experiment.

The object of my invention is to provide a machine that will take straw, hay, grain, or similar substances, from a stack or wagon, and convey it to a thrashing, cutting, or other machine, or load it into a wagon or other receptacle into which it is desired to deposit it.

Referring to the accompanying drawings, Figure 1, Sheet 1, is a perspective view of my machine ready for action. Fig. 2, Sheet 2, is a view of the machine closed for transportation. Fig. 3 is a plan view of the base. Fig. 4 is a section of a part of the machine.

A represents a wagon-bed, sled, or other portableframe. Upon this frame or bedlsecure or oonstructa turn-table, B, which can be conveniently rotated by a crank shaft, C, pinion (l, and rack e, or by other similar means. Upon this turn-table I then construct an upright frame, D, which is as wide as the size of the turn -table will permit, and as high as desired. Upon each side of the upper end of this frame, I secure a horizontal metallic or other strong beam or bar, f, so that it will project out at one side. This beam is formed in one piece with strong brace,beam, or bar g, so that the brace g will'support the outer end of the beam f from the timber of the frame D, in the usual manner of applying a brace. The carrier frame is composed of four sections or frames, E E F F, which are pivoted together at their ends in the manner of constructing an extension-lever frame or lazy-tongs, so that the carrier-frame will be both extensible and adjustable. Each section is composed of two sideboards, between the ends of which the rollers G G G, which support the endless carrying belt H, are placed, so that the journals of therollers serve as pivots, to connect the ends of the side boards, The side boards of the section E, or first upper section of the extensible frame, are pivoted, near one end, to the outer end of the horizontal bars f, so that their extremities m extend across and beyond the frame D, as shown. These extremities or extensions serve as levers, to raise and lower the carrier-frame, as hereinafter described. These side-boards extend out from the frame D to the desired distance, and have their outer ends secured to the journals of the roller G. The side-boards of the second section, F, also have one end secured upon the journals of the roller G, while their opposite ends are secured by a pivot, i, which passes through the flange j of the outermost roller, G, and to one side of the center of the roller. These two frames compose the two upper sections of the extensible frame, while the.

frames E F, which compose the lower part of the frame, are connected in a similar manner,

with the exception that the end of the frame E which is pivoted to the brace -beam g is slotted at K, and has no lever-extension like the side-boards of the upper frame E. The outermost end of each of the side pieces of the sections F F has a toothed segment, I, secured to it, so that the segments lwill engage with each other, and thus cause the lower sections, E F, to move in a counter direction to the movement of the upper sections.

A flanged drum or roller, I, has its journals bearing in the braces g, midway between the pivoted ends of the sections E F, and this drum or roller serves to drive the endless belt H, which passes around the extensible frame, upon the rollers.

Across the lower part of the frame D I secure two shafts, M N, one upon each side of the frame. These shafts are operated by means of cranks, and are near enough to the bottom of the frame to allow the cranks to be operated by the person whose duty it may be to ad just the extensible frame. A rope, cord, or chain, 0, has one end secured to the end of the extension on of each side-board of the section E, and passes down around the shaft N, to which it is secured, so that by turning the shaft N in one direction the outer end of the extensible .frame will be elevated, and by turning itgin the opposite direction the frame 'will be'lowered. A pawl, or, acting on a ratchet-wheel, on this shaft, retains the shaft in any desired position. Y

Each of the cords p which pass around the opposite ends of the "shaft M extend upward over pulley q on the sides of the section E, and thence forward along the sides of the section...E to near its front end, where they pass over another pulley, 1'; thence they pass down, and the hook a on their ends is secured in an eye, b, at about the middle of the sides of the section E. Now, by winding the cords 1) upon the shaft M the lower sections E F of the frame are drawn upward, so that the frame is lengthened, and by unwinding it the lower sections drop down and shorten the frame.

It will thus be seen that I am able, by simply turning the shafts M N, to raise or lower the outer end of the frame, and shorten and lengthen it at will, and a great advantage which I secure is, that the different positions which the sections assume in shortening and lengthening the frame are specially adapted for taking straw or grain from a stack.

The endless carrying-belt H is provided with a transverse series of hooking-teeth, s s, at intervals entirely around its length. The driving shaft or drum Iris driven by a belt, T, from the shaft U, and this shaft can be driven by any suitable connection with the thrashing or other engine or power.

V is a flexible chute, which consists of pivoted sections, in the usual manner of constructin g a flexible chute. The upper end of this chute is secured to the frame 1) below the roller 1, over which the endless belt passes.

A shaft, IV, which is armed with long teeth,

extends across the top of the frame D, 1ts ends bearing in the upper ends of the frame.

This shaft is driven by a belt-connection with the same shaft which drives the roller I, and is located far enough from the travelingbelt to cause its teeth to pass between the curved teeth 8 s, and clear them of their load of straw, hay, or grain, so that it shall fall into the upper end of the chute V, and be conveyed by it to the machine or place into which it is intended to feed it.

An extensible coupling-shaft or tumblingrod, X, can be used for connecting the engine or other driving shaft with the shaft U, from which the elevator is operated, so that the connection can be easily made without particular adjustment. A strong bow or bale, Y, is secured upon the frame 1), upon the top of which is a hook, X.

A guyrope can be secured to this hook, and its opposite end anchored to the ground at a convenient distance away, so as to counteract the leverage of the frame D when it is extended and in use.

Theframe A will usually be mounted upon wheels or placed upon an ordinary wagon, so

that it can be easily moved from place to ing the shaft M the outer sections E F are drawn inside of the sections E F, so as to shut up the frame inside of the length of the sections E F.

The frame can then be lowered, as at Fig.

2, thus reducing it to a small compass, and disposing it conveniently for transportation.

With this machine, it will be readily seen that straw, hay, or grain from a stack or pile can be taken up and carried to a thrashing or other machine, or to a wagon, with great ease.

Having thus described my invention, what I claim, and desire to secure byLettcrs Patent,

1. The extensible and adjustable frame consisting of the sections E E F F, pivoted together at their extremities, as set forth, in combination with the roller I and endless carrying-belt H, substantially as described.

2. The section E, pivoted as described, and having the lever extensions m connected with the shaft N by cords O, in combination with the sections E F F, substantially as and for the purpose above described.

3. The sections E F, having the toothed segments l, and connected to the flange of the outermost roller G in the manner described, for the purpose specified.

4. The hinged sections E E F F connected as described, in combination with the shaft M, cords p, with their hooks a, pulleys 0, q, r, and I), combined and arranged substantially as and for the purpose specified.

5. The combination of the endless carrier or belt H, armed with its hooking-teeth s s, with the toothed shaft or picker W and the chute V, arranged to operate as above described.

In witness whereof I hereunto set my hand and seal.

DAVID MOREY. [L. s]
