Specification of Letters Patent.

Patented Sept. 4, 1906.

Application filed March 13, 1906- Serial N0. 305,910.

To (1 111710712 it may concern:

Be it known that I, HENRY B. ZIMMER- AN, a citizen of the United States, residing at Raymond, in the county of Kandiyohi and State of Minnesota, have invented a new and useful Hay-Richer, of which the following is a specification.

This invention relates to hay rickers or loaders, and its object is to provide a device of this character having a fork of novel construction to raise hay or other material to a desired point, whereupon the same will be discharged automatically, thus permitting the operator to properly build the hay-stack.

With the above and other objects in view the invention consists of a base having side beams pivoted thereto and provided at their upper ends with a stationary fork-section. Another fork-section is pivoted to the firstmentioned section and is normally supported at right angles thereto by resilient means provided for that purpose. An actuatingbeam is pivotally mounted upon the base and connected to the forks so as to swing the side beams to a desired angle in relationto the base. This beam is adapted to be actuated by any suitable power. Adjustable means are also employed for causing the swinging fork-section to automatically discharge the load after the fork reaches a predetermined position.

The im'ention also consists of certain other novel features of construction and combination of parts, which will be hereinafter more fully described, and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In the said drawings, Figure 1 is a perspective view of the device in position to receive material prior to discharging it upon a stack, and Fig. 2 is a side elevation showing the position assumed when the load is being discharged.

Referring to the figures by numerals of reference, 1 1 are the sides of the base of the loader, and 2 and 3 are the end beams which are secured thereon, said side beams being preferably beveled at their ends, so as to facilitate dragging the loader from place to place. A cross-rod 4 is secured upon the side beams 1 near the forward end thereof and constitutes the pivot of the fork-frame. This frame is formed with upstanding beams 5, connected at their u per ends by cross-stri s 6, and secured on t ese cross-strips are t e fingers 7, constituting the stationary section of the fork. A series of connected fingers 8 is pivoted to the lower ends of fingers 7, and rods 9 are pivotally connected to the fingers 8 and slide within guides 10, extending laterally from the beams 5. Coiled springs 11 are disposed upon the rods 9 and hear at opposite ends on the guides 10 and the movable fork-section 8, respectively. These springs serve to normall hold the movable fork-section substantialfy at right angles tothe fingers 7. Holdback ropes or cables 12 extend from the lower ends of the rods 9 and are adjustably fastened in any desired manner to a beam 13, which is pivotally mounted on the rear end beam 3 and is adapted to hold the ropes 12 normally taut.

An actuating-lever 14 is disposed upon the .base and projects through the fork-frame 5.

This lever consists of converging pairs of uprights 15, said pairs being spaced apart at their upper ends by a connecting-strip 16, so as to give the actuating-lever a triangular appearance. The connecting-strip 16 thereof is attached to the side beams 5 by means of rods 17, and a pulley 18 is secured to the lower end of this connecting-strip 16 and also to the center of the front end strip 2. A cable 19 is secured to said end strip 2 and extends around the pulleys. Its free end is adapted to be attached to any suitable power. In using the apparatus herein described the fork is swung downward into position adjacent the rear end beam 3 and a quantity of hay or other material to be stacked is placed upon the fork between the two sections thereof. Horses can then be connected to the cable at 19 and when driven forward will swing the lever 14' downward. An upward pull will therefore be exerted upon the fork and its frame by the rods 17 and the forksections will be carried to a predetermined elevation, whereu on the ropes 12 will become taut and pu l downward on the rods 9. This will result in the pivoted fork-sections swinging downward so as to discharge the material therefrom. The downward movement of the fork-section 8 will of course tension the springs 11. As soon as the load has been discharged in this manner the parts can be returned to their original position by pressing backward on the fork-frame until the parts have passed the center of gravity. Of course as soon as the ropes 12 become slack the springs 1 1 return the movable forksection to its original position. By lengthening or shortening the ropes 12 the fork can be caused to discharge its load at predetermined points during its u ward movement.

If desired, chains may e connected to the ends of the rods 9 and may be adjustably connected to hooks upon the side beams 5, so as to limit or prevent movement of the rods, as may be deemed necessary.

By means of mechanism such as herein described a load of hay can be stacked at any desired point and the material carried by the fork can be accurately discharged at predetermined oints, so as to permit the operator to proper y build the stack. The pivoted beam 13 serves to keep the ropes 12 normally taut, so as to prevent them from becoming entangled in any parts of the mechanism.

I claim A 1. A device of the character described comprising a base, a fork-frame pivotally supported upon the base, a statlonary forksection secured on the frame, a pivoted forksection upon the frame, a resi ient support for said pivoted section, means for swinging the frame upon the base, and means for automatically swinging the pivoted fork-section to unload at predetermined points.

2. The combination with a base; of a fork frame pivotally supported thereon, means for swinging the frame upward from the base, a fork-section rigidly connected to the frame, a fork-section pivotally connected to the frame, a resilient support for said pivoted section and adjustable means for automatically swinging the pivoted fork-section at predetermined points during the upward movement of the frame.

3. The combination with a base; of a forkframe pivoted thereon, means for swinging the frame u ward from the base, a fork-section pivotally connected to the frame, a resilient support therefor and adjustable means for contracting the support at predetermined points during the movement of the atoms frame to swing the fork-section into unload-- ing position.

4. The combination with abase; of a forkframe pivoted thereon, means for swinging said frame upward from the base, a fork-section pivoted upon the frame, guide-rods depending therefrom, resilient fork-sup orts mounted on the rods, and an adjustable lioldback device connected to the rods.

5. The combination with a base; of a forkframe pivoted thereon, means for swinging the frame upward from the base, a pivoted fork-section mounted on the frame, a resilient support for said section and a holdback device'adjustably connected to the base for actuating the pivoted fork-section at predetermined points during the upward movement of the frame.

6. The combination with a base; of a forkframe pivoted thereon, means for swinging the frame u ward from the base, a fork-section pivote upon the frame, guide-rods depending therefrom, resilient fork-supports upon the rods, a holdback for tensioning the supports and actuating the fork-section at a predetermined point during the upward movement of the frame.

7. The combination with a base; of a forkframe pivoted thereon, means for swinging the frame u ward from the base, a fork-section pivote upon the frame, guide-rods dependlng therefrom, resilient fork-supports upon the rods, aflexible holdback connected to the rods and adapted to tension the s ring and actuate the fork-section at a pre etermined point during the upward movement of the frame, and means for maintaining said holdback taut.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of twowitnesses.
