COMBINATION HAY STAOKER AND LOADER.

Application filed December 4, 1923.

This invention relates to a combination hay stacker and loader and is designed to provide an apparatus whereby the hay may be more conveniently placed upon the sling when in loading position upon the ground, means whereby the sling may be moved or elevated to unloading position with relation to the stack, and means whereby the sling may be released from the draft mechanism and permitted to fall by gravity for reloading.

The invention resides first in the novel arrangement of sling spreading and holding means to permit loading; second, in the specific construction of the sling; third, the construction of the upper portion of the derrick which includes a folding arm and fourth, a novel form of draft and trip release device for releasing the sling after unloading.

In the acompanying drawings Figure 1 is a side elevation of the derrick and the sling carried thereby in operative position;

Figure 2 is a side elevation thereof in condition for transportation;

Figure 3 is a side elevation of the draft cable trip and release device;

Figure 4 is a top plan view thereof, and

Figures 5 and 6 illustrate details of construction referred to in the accompanying specification.

Figure 7 is a plan View of this stacking sling.

Figure 8 is a detail view of hooks and stakes.

Referring now to the drawings by numerals of reference, 10 indicates generally the derrick of the stacker, said stacker being in the main, of a nature similar to those now in use, and consisting of the lateral vertical beams 11, having transverse braces 12, the rear inclined braces 14 and the base beams 15 usually arranged in rectangular formation.

At the junction or apex 16 of the vertical beams 11 is pivotally mounted to swing in a vertical plane, on a pivot bolt 18, a rocking arm or beam 19 having at its outer or longer end, a block and pulley 20, the rear or shorter end being also provided with a similar pulley 21. The arm or beam 19 is supported in operative or substantial Serial No. 678,523.

horizontal position through a pair of braces 22 hinged or pivoted at 24 to fold, when not in use, alongside the vertical beams 11.

Extending transversely of the derrick and suitably secured to the vertical beams 11 at the proper distance from the base of the derrick, is an axle 25, on the outer ends of which are wheels 26 of suitable diameter and construction and are for the purpose of permitting transportation of the derrick when it is tilted so that said wheels rest on the ground. During transportation, the arm 19, is folded so that the inner and shorter end lies within the upper portions of the lateral beams 11 and a hook 21. at the outer end of said arm, which is utilized to mount the block and tackle 20, may be connected with the neck yoke of a draft-horse or may be coupled with a tractor hitch. A guy wire or cable 28 connected at its upper end with the top of the derrick in any suitable manner has attached at its lower extremity, a chain 29 which is adapted to be secured to a stake driven into the ground at the rear of the apparatus. Obviously, this guy wire prevents overturning of the derrick during stacking operations.

The stacking sling, comprises a plurality of ropes 30 the free ends of which are provided with eyes or rings 32, while their other ends are joined and connected with a pulley 33, said ropes being spaced adjacent their joined ends through a rigid spanner bar 34.

The sling is raised and lowered through a draft rope or cable 35 which is fixed at one end to the pulley block 20, passes thence around the pulley 33, returned on itself, passing over the pulley 20 at the outer end of the arm 19, over the pulley 21 at the rear end of said arm, and finally around a pulley 36 secured at the lower portion of the derrick frame. The free end of the cable 35 is provided with a ring or eye 40 which cooperates with the trip mounted on the cart 42, the arrangement of which will be presently described.

In loading the hay, onto the sling prior to stacking, the sling is permitted to be lowered and laid flat upon the ground, the eyes of the ropes being respectively connected with hooks 44 pivotally secured to horizontal extensions 45 of stakes 46 driven full length into the ground, the throats of the hooks opening downwardly to avoid catching the hay therein when it is being raked or otherwise moved onto the sling. It will be understood that the position of the stack to be formed is located intermediate the sling loading position and the stacking derrick.

The sling when filled, is moved over the stack being formed through draft on the rope or cable 35, the eye 40, of which is placed over a trip linger l8, perpendicular to the arm of a trip lever 51, pivoted on a pin or bolt 52 passing transversely through the outer end of an upwardly channeled bar 5st secured by bolts and 56, to a rear extension 59 of the cart tongue 60.

lvhen in a position to retain the eye or ring IQ of the draft rope, 35, the trip finger 48 is in a vertical position, while the arm 50 lies in a horizontal plane within the channel of the bar 54., at which time the nose 62 of said arm 50 is confined beneath a transverse pin 64: of an inverted U-shaped releasing handle 66, the lower end of the legs of which are pivoted at 68 to the sides of the bar 54:.

During the stacking operations, the eye of the draft cable is retained by the trip finger 48 and at a period therein, when it is desired to dump the hay from the sling, a releasing hook 70 is operated from a cord 7 2 to permit the sling ro es 30 to be opened to release the hay. The operator on the cart, then swings the handle 66 to permit the trip bar to be tilted on its pivot 52, whereupon the said eye or ring 10 will ride off the trip finger and the sling will fall by gravity to the ground to be again loaded.

In operation the rings 32 carried at the free ends of the sling cables 30 are connected with the hooks 44 and the said sling cables are stretched over the surface of the ground. The hay is then moved over the sling cables 30 by a push rake in a usual manner and deposited upon the said cables. The push rake is then withdrawn and the rings 32 are disconnected from the hooks 44- and the free end portions of the cables 30 are brought up over the hay and all of the rings 32 are engaged with the end of the trip hooks 70. The cable 35 is then drawn Whereby the bundle of hay is elevated and when the bundle is at a desired height the trip hook 70 is withdrawn from the rings 32 by exercising a pull upon the cable 72. Thus the free ends of the cables 30 are released and the bundle pulled in position upon the stack of hay which is being formed.

From the foregoing description of the construction of my improved apparatus, it will be seen that I have provided a simple, inexpensive and eflicient means for carrying out the objects of my invention and while I have particularly described the elements best adapted to perform the functions set forth, it is obvious that various changes in form, proportion and in the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the principles of the invention.

lVhat I claim as new and desire to protect by Letters Patent is 1. A hay stacker comprising a normally horizontally disposed base, a pair of divergent standards extending vertically there from and connected together at their upper ends, a beam pivotally mounted to the upper ends of the standards, links pivotally connected with the beam and standards, one end of each of the links being detachably connected to the beam whereby to permit such beam and the links to extend in the same plane as the standards when not in use, pulleys carried by the beam, a flexible element trained over the pulleys, a hay sling opera tively connected with the flexible element, and ground engaging wheels carried by the standards, the structure being adapted to be arranged in a position where the standards will be disposed horizontally and the ground engaging wheels engaged with the ground when it is desired to move the structure from place to place.

2. A hay stacker comprising a base includ ing a pair of horizontally arranged bars, adapted to normally rest upon the ground, a pair of vertically arranged standards carried by the normally horizontally disposed bars, brace elements connecting the standards and normally horizontally disposed bars together, a lever pivoted to the upper ends of the standards, a hay stacking rigging associated with the pivoted lever, and ground engaging wheels carried by the vertical standards and adapted to engage the ground to support the standards in a horizontal plane when it is desired to move the stacker from place to place.

' In testimony whereof I affix my signature.

EDGAR- C. JENSON.
