useful Improvements in Hay-Stackers, of

which the following is a specification.

This invention relates to hay stackers and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a stacker of simple and durable structure adapted to be transported readily from place to place, and which includes a frame having standards mounted thereon with stops adjustably mounted upon the standards. Arms are pivotally mounted upon the frame and carry at their free ends sleeves which slidably receive the said standards, and which are adapted to encounter the said stops, whereby the swinging movement of the said arms is limited. A cradle frame is pivotally connected with the free end portions of the arms, and carries at its free end a cradle adapted to receive the hay. A derrick is pivotally mounted upon the frame and is operatively connected by means of rods with the cradle frame. Block and tackle means are provided for swinging the derrick and cradle frame. A weighted lever is fulcrumed upon the first mentioned frame, and is operatively connected with the cradle frame to limit the swinging movement of the cradle frame and to cause the same to descend promptlyafter the cradle frame has deposited its load.

In the accompanying drawings :-Figure 1 is a side elevation of the stacker, Fig. 2 is a top plan View of the same, Fig. 3. is an end elevation of the same, Fig. 4 is a vertical sectional view of the same.

The stacker includes a main frame which consists of runners 1 having vertically disposed standards 2 mounted upon one end thereof. Castings 3 serve as means for holding the standards 2 in proper position upon the runners 1. The runners 1 are connected together by cross bars 4, 5 and 6, and suitable braces are provided between the cross bars and standards 2. Castings 7 connect the upper ends of the standards 2 with the said braces, in a manner as best shown in Fig. 3 of the drawings.

Standards 8 are mounted at the intermediate portions of the runners 1 and are disposed vertically with relation thereto.

Braces 9 connect the upper ends of the standards 8 with the upper ends of standards 2 and inasmuch as the standards 8 are shorter than the standards 2, the said braces are downwardly inclined toward the intermediate portions of the runners 1. Stops 10 are adjustably mounted upon the standards 2, and ny suitable means may be employed for securing the said stops at adjusted positions upon the said standards.

Arms 11 are pivotally connected at points between their ends tothe upper portions of the standards 8, and the said arms carry at one end, sleeves 12 which slidably receive the standards. 2 and which are adapted to encounter the stops 10, whereby the swinging movement of the arms 11 is limited. The forward ends of the arms 11 are connected together by a cross bar 13, the ends of which project beyond the outer sides of the said arms.

A cradle frame is pivotally connected with the arms 11 in the vicinity of the sleeves 12, and said cradle frame includes side bars 14 connected at'their free ends with the cross bars 15. Tines 16, are attached to the cross bars 15 and are spaced at desired intervals apart. Cross braces 17 connect the free ends of the side bars 14 together, and braces 18 connect the bars 14 with the bars 15.

, Tines 19 are pivotally connected at one end with the end portions of the tines 16, and the said tines 19 are connected together by across bar 20. Props 21 are pivotally connected with the cross bar 20 and are provided at one side with notches 22 adapted to engage the pins 23 mounted at the inner sides of the bars 14, whereby the tines 19 are held at desired angles with relation to the tines 16. Y

A derrick 24 is pivotally connected with the upperend portions of the standards 8 at points above the points of. pivotal connection between the arms 11 and the said standards. A lever 25 is fulcrumed at the upper end of the derrick24, andelements 26 connect one end of the said lever with the forward ends of the side bars 14. A pulley block 27 is carried at the other end of the lever 25. Pulley blocks 28 and 29 are loosely mounted upon the cross bar 4. One end of a cable 30 is attached to the block 27 and is then trained around the pulley carried in the block 28, thence around the pulley carried in. the block 27, and thence around the pulley carried in the block 29.

One end of the said cable is disposed out beyond the side of the stacker and draft animals or other suitable pulling means may be applied thereto.

A lever 31 is fulcrumed at one end to the cross bar 6 and extends back transversely over the cross bar 5. Said lever is provided at its free end with a box 32 adapted to receive a suitable weight, as for instance; stone, sand or earth. An eye 33 is mounted upon the intermediate portion of the lever 31, and cables 34 are connected at one end with the said eye, and the other ends of the Said cables are connected with the free end portions of the side bars 14 as best shown in Fig. 4. The intermediate portions of the cables 34 are trained over the'base portion of the derrick 24. Cables 35 are connected at one end with the eye 33, and the intermediate portions of the said cables 35 are trained through eyes 36 mounted at the upper ends of the standards 2, and the ends of the said cables 35 are attached to the arms 11 in the vicinity of the sleeves 12 carried thereby.

In operation, the tines 16 are permitted to lie upon the surface of the ground, and hay is loaded upon the said tines 16 and against the tines 19. Previous to this, the props 21 have been adjusted upon the pins 23 so that the tines 19 are supported at a desired angle with relation to the tines 16. V hen a sufficient quantity of hay has been placed upon the cradle of which the tines l6 and 19 are component parts, a pulling strain is exerted upon the cable 30 whereby the said cable is moved longitudinally, and the lever 25 and the upper end of the derrick 24 is drawn toward the cross bar 4. During this swinging movement of the derrick, the rods 26, which connect the lever 25 with the forward ends of the side bars 14, swing the free ends of the said side bars in an upward direction, and inasmuch as the said side bars are pivotally connected with the arms 11, the arms and "the sleeves 12 are moved in a downward direction along the standards 2.

When thesleeves 12 encounter the stops 10, the arms 11 come to a state of rest, but the side bars 14 continue in their upward swinging movement. As the side bars 14 arrive at the limit of their upward swinging movement, the cables 34 become taut and the weighted end of the lever 31 is swung in an upward direction and assumes the position shown in Fig. 4. When this happens, the side bars 14 come to a state of rest and the hay which is carried by the tines 16 and 19 is permitted to gravitate from the endsof the tines 19 upon the stack or upon the ground at the end of the stacker.

When it is desired to return the parts to their initial or normal positions, thepulling strain is removed from the cable 30, whereby the weighted end of the lever 31 descends and the cables 35 are moved longitudinally as the arms 11 are swung in an upward direction. At the same time the lever 31 exerts, through the cables 34, a pulling strain upon the side bars 14 and the said bars, together with the cradle carried at the ends thereof, move in a downward direction. When the bars 14 strike the projecting end of the crossbar l3,the arms 11 are swung, whereby the sleeves 12 are moved in an upward direction along the standards 2, and this continues until the tines 16 strike the surface of the ground.

From the above description taken in conjunction with the accompanying drawings, it will be seen that a hay stacker of simple and durable structure is provided, and that lever mechanisms are provided to assist in the initial movement of the cradle from the ground in an upward direction and to cause the same to move promptly from an elevated position toward the ground.

Having described the invention, what is claimed is: e

A stacker comprising a frame, stops adjustably mounted thereon, arms pivoted upon the frame and having sleeves adapted to encounter the stops whereby the swinging movement of the arms is limited, a cradle having side bars pivotally connected with the arms, a derrick pivotally mounted upon the frame and connected with the side bars of the cradle, and means for swinging the derrick.

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