SPECIFICATION forming part of Letters Patent'No. 791,533, dated June 6, 1905.

Application filed December 12, 1904. Serial No. 236,585.

To all whom it may concern:

Be it known that I, HERMAN BERGMAN, a citizen of the United States, residing at Ogallala, in the county of Keith and State of N ebraska, have invented a new and useful Hay- Stacker, of which the following is a specification.

This invention relates to devices for stacking hay and the like; and it has for its object to simplify the construction and to improve and facilitate the operation of this class of devices.

The invention consists in the improved construction and novel arrangementand combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

1n the accompanying drawings has ,been

illustrated a simple and preferred form of embodiment ofthe invention, it being, however, understood that no limitation is necessarily made to the precise structural .details therein exhibited, but that the right is reserved to any changes, alterations, and modifications to which recourse may be had within the scope of the invention and without departing from the spirit orv sacricing the efliciency of the same.

In said drawings, Figure l is a perspective view illustrating a skid or frame which constitutes a part of the invention and showing also a follower or pusher which constitutes another part of the invention, said follower or pusher being represented in the position which it occupies with relation to the skidframe when the latter is to be moved from one place to another. Fig. 2is a perspective lView of the lower end of the skid-frame and showing also a portion of the pusher-frame in the position occupied by the latter when returning after the delivery of a load. Fig. 3 is a vertical sectional view through a portion of the skid-.frame and showing in elevation one of the lifting-arms and related parts. Fig. 4 is a sectional detail View taken through the pusher-frame adjacent to one of the transporting-wheels and showing also the lower end of the skid-frameconnected therewith for transportation. Fig. 5 is a side elevation showing the device in position for operation,

with dotted lines showing the position of the parts when the load is being discharged over the skid. Fig. 6 is a transverse sectional de- '.tail view taken near the upper end'of the skid.

Fig7 is a sectional detail View, on an enlarged scale, taken on the line 7 7 of Fig. 5.

3, the cross-piece 2 being secured upon the front endsof the sills, while the cross-piece 3 is supported upon the upper sides of said sills near their rear ends. The sills l l in rear of the cross-piece 3 support uprights 4 4, to the 'bars are braced and reinforced by means of braces 6, extending from said curved bars to the sills at suitable intervals.

The upper ends of the curved bars 5 5 are extended above and in rear of the uprights 4 and are connected by a cross-bar 7, provided with a rib 8, which constitutes a stop. The curved bars 5 5 support a plurality of transverse bars 9, which in turn support a plurality of slats 10, which are curved to approximate the curvature of the bars 5. The lower ends of these slats are secured upon the framebar 2, and their upper ends are secured upon the'cross-bar 7 where they abut upon the rib 8. Guide-bars 11 are provided, the upper ends of which are secured upon the cross-bar 7, at the ends of the latter, and the lower ends of which are secured upon the cross-bar 2, said guidebars being intermediately supported upon the transverse bars 9. These guide-bars are of greater thickness than the slats l0, and they are for the vpurpose of-preventing lateral displacement of the follower, which is to be hereinafter described, when said follower moves over the skid.

In addition to the slats 10' the skid-frame is provided with -auxiliary slats l2, the upper ends of which are secured to the cross-bar 7 and the lower ends of which are secured to and supported by cross-braces 13, which connect pairs of adjacent slats 1Q 10, saidcrossbraces being disposed a short distance above one of the transverse bars 9 near the lower end of the skid-frame. Hingedly connected with the curved bars 5, near the lower ends of the latter, are lifting-arms 15, which are preferably mounted pivotally upon rods 16, extending through the bars 5, the guides 11 and short bars 17 suitably spaced from the lower ends of the curved bars 5, the liftingarms b,eing disposed between the latter and the bars or braces 17. Said lifting-arms are supported with their upper ends in a raised position by means of cushion-springs 18, supported upon cross-pieces 19, which connect the bars 5 with the braces 17. Retractingsprings 2O are arranged to force the free ends of the lifting-arms normally in a downward direction toward one=of the transverse bars 9; but the free ends of the lifting-arms are normally held by the cushion-springs somewhat elevated above the level of the adjacent portions of the curved slats 10, as will be-clearly seen by reference to Figs. 1 and 3. The under sides of the lifting-arms are provided with hooks 21.

Hingedly connected with the cross-bar 2, at the lower end of the skid-frame, is a-n extension-frame 22, composed of cross-pieces 23, connected by a plurality of slats 24, the points of which are adapted to rest upon the ground when the device is in position for operation, so as to cause the material which is to be elevated to slide readily onto the skid-frame.

The skid-frame is reinforced wherever needed by braces and d-iagonals, and the rear uprights 4 4 are connected Aat a suitable distance above the cross-bar 3 by a cross-bar 25. The cross-bars 3 and 25 have bearings for vertical shafts 26, the lower ends rof which are provided with crank-axles 27, carrying casterwheels 28. The upper ends -of the shafts 26 are provided with cranks 29, connected by a cross-bar 30, which has pivotal connection with a lever 31, fulcrumed upon the cross-bar 25. This mechanism constitutes a steeringgear by means of which the skid-frame may be guided when it is to be moved, as will be hereinafter described.

The pusher or follower, which is used in connection with the skid-frame, includes an arched axle 32, having wheels 33 and provided with bifurcated draft-bars 34, pivotally connected with the spindles in such a manner that the wheels will engage the forks of said draftbars, thus enabling the latter to be turned or swung in a forward or rearward direction, as may be desired. The swingletrees 35 are connected, by means of links 36, with the extended ends of the spindles 37, so that said swingletrees may likewise be turned or shifted from one side to the other. Suitably connected with the aXle 32 is a frame consisting, essentially, of side members 38, connected and spaced apart by diagonals 39 and also connected at their outer or front ends by a cross- 4an approximately horizontal position.

bar 40, which is of a length to fit accurately between the guide-bars 11 of the skid-frame. rlhe cross-bar 40 constitutes a head, to the front side of which are secured a plurality of uprights 41, connected with cach other by a cross-bar 42, the latter being connected by braces 43 with the side members 38. Additional obliquel'y-disposed braces 44 and 45 are provided to reinforce this part of the device, which may be generally designated as the pusher-head or the "follower-head. The cross-bar 40 is provided with rounded portions 46, forming bearings adapted to engage the hooks 21 of the lifting-arms.

Suitably connected with the cross-bar 2 at the lower end of the skid-frame are hooks 47, adapted to be placed in engagement with the arched axle of the pusher-frame for the purpose of elevating the lower ends of the skidframe from the ground for transportation.

In operation the follower-frame is initially lowered from the skid-frame and arranged at a suitable distance from the latter, draft-animals being attached to thc whiiiletrces at ythe ends of the arched axle and the follower-heini being permitted to rest upon the ground, the skid-frame being disposed in the position where it is ydesired to build the stack. The hay or other material that is to be stacked is gathered by means of rakes of the ordinary description, and it is deposited upon the extension-frame at the lower end of the skidframe. The follower-frame is now moved in the direction of theskid-frame, and the follower-head will impact upon the mass of hay and push the same in an upward dircctioi'i upon the skid-frame, the cross-bar 4() of the pusher-head being guided between the bars 11. Owing to the curvature of the slats and bars which constitute the skid-frame, which curvature isin a downward direction, no great power will be required to effect the iirst portion of the lift when the pusher-frame is in As the draft-animals approach the skid-frame, however, the pusher-head, following the cu rvature of the track, commences to travel more decidedly in an upward direction; but at this time the axle, which constitutes the fulcrum of the lever formed by the pushcr-fran'ic, moves 1n the direction of' the perpendicular of the load, and the draft-animals will thus operate to better advantage in raisingor lifting the latter. When the pusher-head approaches the upper end of the skid-frame, the load will be dumped over the upper edge ol the latter and onto the stack.

While one load is being elevated another 'load may be deposited at the foot of the skidframe, and when vthe pusher-frame is returned to its initial position, which may be accomplished either by backing the draft-animals or by reversing the positionof the draft-hars and whiffletrees and facing the animals about, the cross-bar 40 will pass under the elevated pense.

ends of the lifter-armsl 15 and engage the hooks 21 upon the under sides of the latter. It is to be noted thatin the upward passage of the load and the pusher-head the lifting-arms will be readily depressed against the `tension of the pushing-springs 19, so as to offer no obstruction. In the downward passage of the pusher-head, however, when the cross-bar 40 or the rounded bearing portions of said cross-bar engage the hooks 41 the liftingbars will turn upon their pivots, thuselevating the pusher-head, as shown -in Fig. 2 of the drawings, and enabling it to clear the load or bunch of hay which may `have beendeposited at the foot of the skid-frame. As soon as the pusher-head passes clear of the lifting-arms the latter are restored to their normal or initial position by the action of the retracting-springs 20, after which theoperation may berepeated.

' When it shall be desired to slightly movev the skid-frame from one position to another, the pusher-frame is .moved onto the skidfram'e until the pusher-.head is near the upper end of said skid-frame, when the hooks 17 may be placed in engagement with the axle, thus slightly raising the lower end of the skid-frame clear of the ground. This may be done without changing the position of the extension-frame, and the skid-frame may now be conveniently pushed in the direction of the arrow in Fig. 1. When the skid-frame is to be moved greater distances, the extension-frame is folded upony the skid-frame, as shown in Fig. 4, and draft may now be applied in the opposite direction to pull the entire machine to any desired position, the skidframe being guided by means of the steeringgear herein described.

This improved hay-stacking device, as will be seen, is extremely simple in construction, and itmay be produced at a moderate ex- By this device heavy loads may be lifted, and the operation is performed speedily and without difficulty. It will be noted that there is an entire absence of ropes and other tackle which is apt to become tangled and which is considered highly objectionable in hay-stacking devices of ordinary construction. Owing to the position of the liftingarms, whereby the pusher-head is enabled to clear a load placed at the foot of the skid, the operation of the device may be made practically continuous and loss of time is avoided.
