T 0 aZZ whom it'may concern.-

Be it known that I, JOHN II. J UNKINS, a citizen of the United States, residing at Upper Sandusky, in the county of Wyandotte and State of Ohio, have invented certain new and useful Improvements in l-Iay-Stackers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make anduse the same.

My invention relates to derrick hay-stackers; and it consists of a stacker having a portable platform to which an upright laterallyadjustable post is centrally secu red and upon which said post can be adjusted to a vertical position when the machine rests uponan inclined surface, with respect to the horizon by means of longitudinally-extensible and contractible guys fastened to or near the upper end of said post and to the corners of the platform, and a rising and descending and laterally-swin gin g derrick secured to said post and riding upon a track-plate thereof, and a fork and suitable operating means, this combination serving for elevating, moving, and dumping the hay; and it also consists in certain constructions and combinations of parts, whereby a speedy, easy, and effectual operation of the hay-stacker is secured, as will be hereinafter described.

The objects of my invention are. to provide a hay-stacker which is adapted to be freely readily accommodated to inclinations of the ground, and operated with slight manual labor. I obtain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a perspective view of my invention. Fig. 2 is an elevation of the same, and Fig. 3 a plan view thereof.

The letter A in the drawings designates a platform; B, an upright derrick-post; O, a derrick; D D D D guys, and E a hay-fork.

The platform A may be of any suitable construction, but preferably is composed of two side bars at, having curved end portions and united by two end bars a, and two central bars o The side bars a, by reason of their curved ends, can be used as runners on which to move the hay-stacker over the ground in .opposite directions, and thebars a a being sufiiciently elevated above the ground, will notinterfere with this operation. The central bars a are provided midway of their length with a central post-supporting block a in which a central mortise a is provided. Into this mortise a rabbeted foot portion 1) of the post B is inserted, said foot portion being of less diameter than the mortise, and thus fitting thesame loosely, so that the post may be inclined either backward or forward or otherwise, with respect to the platform A, to any degree answering the steepest slope upon which the hay-stacker is to be operated, and thereby always keeping the post in a position at about a right angle to the horizon. The top of the post B may be provided with an eye I), to which the ends of three guy-rods D D D are attached, and a lower eye 6 to which a short guy D is attached. These four guys are connected to the ends. of the bars a by means of eyes a and they are at a suit able altitude provided with turn-buckles d, or other equivalent means, by which they may be shortened or lengthened.

Above the platform A the derrick-post B is provided with a horizontal derrick-riding track-plate b which supports the principal weight of a derrickO, hinged to the upper portion of the post, by means of eyes a o and long staples 1) b in such a manner as to permit the necessary vertical movement and lateral swinging motion of the derrick, as will be presently described. The foot of the derrickis provided with an anti-friction roller 0 which rests on an inclined track b of the plate 19 while being loaded, and by traveling down its inclination facilitates the swinging forward of the loaded derrick. Diametrically opposite the track 5 a wedge-shaped limitation-stop b is provided, against which the roller 0 will abut and gradually run thereon as soon as it escapes from the track 19 and the plate lfi-that is, in the event of the force applied carrying it beyond the plate b From this stop the derrick will fall back upon the plate b by its own weight. A rope-block e is provided on the swinging end of the horizontal arm 0 of the derrick, and a rope e is passed around it, and at e e other similar blocks are provided upon the plate 12 and the frame A in order that the rope may be guided too to a position near the ground, convenient for its attachment to a horse. From the block 6 the rope e suspends the hay-fork E by means of a bail e fastened to the head a of the fork. The fork E is provided with prongs e and a handle e to which a cord a is attached.

The stacker described can be moved to its several places of use without being taken to pieces, and will be ready for operation on its arrival,nnless the, ground is inclined and the derrick-post B consequently is found not to be vertical with .the horizon. In the latter case the turn-buckles d on the lower side of the platform A are turned so as to lengthen the guys, and those on the higher side turned so as to move the post 1) into its proper vertical position. The hay to be stacked is taken from a place in front of the track-say that indicated by a *-by the operator inserting the prongs of the fork E into the mass of hay, whereupon the horse (not shownlattached to the rope c pulls up the fork with its load and keeps it suspended, the operator by means of the cord a holding said fork in a horizontal position, and at the same time following the block 6, which is swung by the derrick 0 around to the stacking-place, (indicated, say, by two such swinging action taking place automatically by reason of the tendency of the roller 0 under the Weight of the derrick and load to run down the inclined surface of the track I). Then the roller 0 finally comes to'a rest upon the horizontal surface of the plate 5 the operator, by slackening the cord a allows the fork and its load to tilt downward, thereby insuring the sliding off of the hay from the prongs e upon the stack, and thereupon the horse is backed toward the hay-stacker and the hay-fork thereby lowered, and the operation just described is repeated. By having the derrick C to rise and descend on staples b b and supporting it on the trackplate b of the fixed post B, and elevating and lowering it on the inclined track b a very light and easily-operated moving haystacker is secured as compared with the cumbersome contrivances wherein the post and united crane-arm are moved togetherin bearings of the platform.

hat I claim as my invention is- 1. In a haystackeigin combination, a movable platform A, which is adjustable from a horizontal to an inclined position and from an inclined to ahorizontal position, a derricksupporting post 13, loosely connected at its lower end to said platform, an elevating derrick, and means for connecting the platform and post, whereby the platform may be set inclined to or kept parallel with the horizon and the post always kept at substantiallya right angle to the horizon, substantially as described.

2. In a hay-stacker, in combination, a platform A, which is adj ustablefrom a horizontal to an inclined position and from an inclined to a horizontal position, extensible and contractible guys or stays, the dcrrickpost B, and a derrick, the said guys being connected to the platform and to the post and said post being attached loosely to the platform, so as to allow the platform to be adjusted in the vmanner stated while it (the post) remains vertical, substantially as described.

3. In a hay-stacker, in combination, a platform which is adjustable from a horizontal to an inclined position and from an inclined to a horizontal position, a derrick-post, a derricksupporting track -plate having an inclined track, a derrick, a friction-roller, verticallyaccommodating hinge connections between the derrick and post, suitable rope-blocks, and a fork, substantially as described.

4. In a hay-stacker, in combination, an adjustable platform A, a derrick-supporting post B, loosely connected to the platform, adjusting and connecting means between the platform and post, a derrick, a derrick-supporting track-plate, andsuitable ropes, blocks, and a device for handling the hay, substantially as described. 5. In a hay-stacker, in combination, a platform A, a post 13, track-plate having inclined track, a derrick, a frictionroller, a vertically-accommodating hinge connection between the derrick and post, suitable means for connecting the post and platform, operating-rope, blocks, and a device for handling the substance to be elevated.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
