CHARLES V. KAHOA, OF RUSSELL, IOWA, ASSIGNOR OF ONE-HALF TO .T. H. HANGOGK, OF BEARGREEK, MONTANA.

PORTABLE HAY-STACKER.

To all whom it may concern:

Be it known that l, CHARLES V. KAHOA, a citizen of the United States of America, and resident of Russell, Lucas county, Iowa, have invented a new and useful Portable Hay-Stacker, of which the followii'ig is a specification.

The object of this invention is to provide im n'oved means for stacking hay.

A further object of this invention to provide means for receiving, elevating, moving laterally and dumping a load or quantity of hay.

A further object of this invention is to provide an improved construction for the carrier or fork of a hay-stacker.

A. further object of this invention is to provide improved means for holding the fork against tilting during the operation of elevating and moving laterally.

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my claims and illustrated by the accompanying drawing, in which- Figure 1 is a side elevation of the machine, the dotted lines illustrating the fork in elevated and dumping position. Fig. 2 is a plan of the machine, the dotted lines showing the fork or carrier turned laterally at right angles to its initial position, preparatory to dumping the contents thereof. Fig. 3 is a cross-section on the indicated line 3-8 of Fig. 1 and Fig. t is a detail rear elevation illustrating the construction of parts of the retaining and dumping mechanism. Fig. 5 is a cross-section on the indicated line 55 of Fig. 2. Fig. 6 is a cross-section on the indicated line (5-43 of Fig. 2 and Fig. 5.

1n the construction of the machine as shown, the numeral 10 designates a post or mast stepped at its lower end in a base 11 suitably anchored in desired location as by stakes 12 driven in the ground. Guys 13, 1 1, 15, in this instance wire ropes, are pivotally connected to the upper end of the mast or post 10 and diverge therefrom. Loops 16 are formed in the lower ends of the guys 13, 14c, 15 and embrace stakes 17, 18, 19 driven in the ground at distances from each other and from the base 11. Arms 20, 21 are pivoted at their inner ends on a bolt 22 extending through the lower portion of the post 10 and said arms extend outwardly in diverg- Specification of Letters Patent.

ing planes from said post. Arms or extension bars 21 are mounted on and overlap the outer ends of the arms 20, 21 and are secured thereto slidably and adjustably by straps or stirrups 23. The outer end portions of the extension bars 20, 21 are connected by a cross bar 2-4:. A fork is provided and is constructed of cross-bars 25, 26 crossing the extremities of the extension arms 20, 21 and tines or fingers 27 fixed thereto, crossing beneath and extending outward from said cross-bars. The cross-bar is hinged or pivoted to the forward ends of the extension bars 20 21, by means of pairs of inter-engaging eye-bolts 20", 21 (Fig. Handles 28, 29 are fixed to and cross above and extend inward from the cross-bars 25, 26 and the inner ends of said handles are directly above the bars 20 21. A bar 30 is slidingly mounted on the rear face of the post 10 and is confined by keepers 31. A cable 32 extends through the lower end portion of the bar 30 (Fig. 4) and has its central portion slidingly engaged thereby. The end portions of the cable 32 extend tln=ougl1 guide sheaves 33 on opposite sides of the post 10 above the lower end of the bar 30, and thence along the arms 20, 21 and extension bars 20, 21 and through guide sheaves 3d on the outer end portions of said bars, and thence vertically to points of attachment, to the inner ends of the handles 28, A yoke 35 is mounted around the post 10, is bent to form a bell-crank and is fulcruined to said post by a bolt 36. A roller 37 is pivoted in the yoke 35 and crosses the rear face of the post 10 above the bar 30. The yoke 35 normally occupies the position shown in Fig. l with the roller 37 engaging the upper end of the bar 30 and preventing upward movement of said bar.

It is the function of the bar 30, held by the yoke and roller 87, to apply strain through the cable 32 and hold the fork or carrier in horizontal position shown with the tines or fingers 2? in position to be loaded with hay by a bull-rake (not shown) in a common and well-known manner. A cord 38 is fixed at one end to one end of the yoke 35, extends through a sheave 39 on the post 10 above the yoke, and to a convenient position to be handled by an operator. Eyestraps 10, 41 are fixed to and project laterally of the crossbar 24k and a cable 42 is fixed at its ends to said eye-straps. The

cable 42 extends through blocks t3, 44 arranged in pairs on opposite sides of the top and central portion, respectively, of the post 10, and the central portion of said cable depends as a loop in front of said post and carries a pulley block &5 loosely suspended therein. A draft cable d6 1s fixed at one end to an eye 47 on the pulley block L5 and extends downward along the post 10 and through one portion of a double foot-pulley 4S, fixed to the foot of the post, thence upward along the post and through said pulley block 4-5, thence downward along the post and through the other portion of the footpulley block, and thence to the rear of the post to a point of convenient attachment to a draft animal or other hoisting power.

\Vhen the fork or carrier is loaded, draft is applied through the cable 46 to pull the block and bight of the cable as ClOW11- ward and cause the cable 42 to raise the outer ends of the extension bars 20 21" and the loaded fork thereon. As the fork is raised it is held in horizontal position, to retain and carry the load, by the cable 32, bar 30 and yoke When the fork has been raised to the desired degree, it, the arms connecting it to the post and the post itself are turned laterally, by manual actu ation, to the desired position, such as indicated by dotted lines in Fig. 2, and then the bell-crank yoke 35 is tripped, by manual draft on the cord 88, to the release of the roller 37 from and the upward movement of the bar 30. Thus the restraint of the cable 32 is released and the fork is permitted to tilt, under the weight of the load thereon, and dump its contents. A spring d9 (dotted lines Fig. 1) connecting the cross-bars 24. and 26 is expanded by tilting of the fork, and upon the dumping of the load from said fork said spring retracts and returns the fork to normal horizontal (though elevated) position and permits the automatic descent of the bar 80 into locked position beneath the roller 87 of the yoke 35. The fork or carrier can be moved through any are permitted by the guys 13 and 15 and said guys can be adjusted into any desired position that will maintain the equilibrium of the post 10.

I claim as my invention 1. A hay stacker, comprising a post stopped for rotary movement, guys pivoted at their upper ends to said post, loops on the lower ends of said guys, stakes in said loops, and adapted to be driven into the ground, extensible arms pivoted to the lower end of said post, a fork hinged to the outer ends of said arms, a bar slidingly mounted on the post, a yoke fulcrumed on the post, a roller on the yoke engaging said bar, means for tripping the yoke, a cable connecting the bar and fork, and block and tackle connecting the post and arms whereby the arms and fork can be raised and lowered.

2. A hay stacker, comprising a post stepped for rotary movement, means for bracing said post, arms pivoted to the lower end of said post, a fork hinged to the arms, means for latching said fork in horizontal position, means for tripping the latching means, a cable fixed at its ends to the outer ends of the arms, pulleys on the post supporting said cable, the central portion of said cable forming a pending loop in front of the upper end of said post, a pulley block suspended in the loop of said cable, a double footpulley block fixed to the lower end of the post, and a draft cable fixed to the suspended pulley block, rove through the foot-block, rove through the upper block, again rove through the foot block and adapted for attachment to draft means.

A hay stacker, comprising a post stepped for rotary movement, means for bracing said post, arms pivoted to the post, a fork hinged to said arms, means for raising and lowering said arms and fork, a bar mounted for vertical reciprocation in sliding engagement with said post, a cable fixed at its ends to said fork and having its central portion slidingly mounted through the lower end portion of said bar, guide sheaves on the arms and post engaging said cable, a bell-crank yoke fulcrumed on the post, a roller on said bell-crank yoke crossing the upper end of said bar and adapted to be engaged thereby, and a cord attached to and adapted for oscillation of said bell-crank yoke.
