Application filed May 5, 1906. Serial No. 315,445-

1'0 all whom it Timmy concern:

Be it known that I, MADs H.-MADSEN, a citizen of the United States of America, and a resident of Kimballton, Audubon county, Iowa. have invented a new and useful Hay- Handling Mechanism, of which the following is a specification.

The object of this invention is to provide improved means for tilting laterally a haycarrying frame, means for leveling or returning said frame to normal position after the same has been tilted. laterally; and improved means for connecting said frame to a supportmg arm.

Other objects of my invention will appear throughout the description of the construction and operation of the device.

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 plan of the complete device. Fig. 2 is a side elevation of the device. Fig. 3 is an end elevaton of the device. Fig. 4 is a cross-section of the device illustrating the means employed to connect the oscillating frame to the supporting arm and the means for holding said frame normally against tilting, and Fig. 5 is a longitudinal section illustrating the same means as Fig. 4.

In the construction of the device as shown the numeral designates a carrier mounted for longitudinal adjustment and occasional travel on a track 11. A curved supporting arm 12 is suspended from the carrier 10 by means of an eye 011 said arm engaging a hook 13 on the carrier. A cross-head or clamp 14 is mounted on and intermediate of the ends of the supporting arm 12 and braces 15, 16 are fixed at their forward ends to the ends of said cross-head and extend rearward and upward therefrom in diverging planes. The upper ends of the braces 15, 16 are connected by a cross-bar 17, and brace-rods 18, 19 are fixed at their rear ends to the rear ends of the braces and extend forward therefrom in converging planes and terminate in a ring or eye 20 adapted. to engageand be supported by a hook 21. on the upper end portion of the supporting arm 12. Cords 23 one only of which is shown in Fig. 2, are fixed at their upper ends to the ends of the cross-bar 17 and depend therefrom in converging planes and are attached to a ring 24, from which ring an operating cord 25 depends. There is no movement or articulation between the braces 15, 1 6, cross-head 14 and supporting arm 12. Bearing- boxes 26, 27 are mounted loosely on the lower forward end portion of the supporting arm 12 and are connected integrally by an arch 28. A plate 29 is mounted on the supporting arm 12 between the boxes 26, 27 and is secured thereto by a pin 30 extending horizontally through the plate and arm. The plate 29 partially embraces the arm 12 and extends laterally from and below said arm and serves to prevent movement of the boxes 26, 27 longitudinally of the arm. A bearing 31 is formed in and trans versely of the apex of the arch 28 and a shaft 32 is mounted through said bearing and secured against longitudinal movement therein by fitting tightly thereto or by means of a set screw 33. A spring 34 is coiled at its center on the bar 12 and extends laterally therefrom through notches in the plate 29 in opposite directions, the end portions of said. spring bent laterally and. engaging with and beneath the shaft 32 on opposite sides of said plate. It is the function of the spring 34 to cushion tilting of the shaft 32, arch 28 and boxes 26, 27 and return them to normal positions after manual tilting as hereinafter described.

A hay-carrying frame 35, of substantially .Ushape is provided with brackets 36, one

of which is shown, depending from the cen-' tral portions of its arms, and said brackets are formed with bearing boxes on their lower extremities mounted loosely on end portions of the shaft 32, whereby the frame is journaled for longitudinal oscillation on the shaft. The side margins of the plate 29 may be engaged at times by and limit lateral oscillation of the shaft 32 and parts carried thereby. The closed end portion of the U- shaped frame 35 is rearmost and is above and adapted to engage at times with the supportingarm 12. Pulleys or sheaves 37, 38 are fixed to and depend from the side arms of the frame 35, and a cord 39 is fixed at its ends to the ends of the cross-head 14, extends through both of said sheaves, and beneath the supporting arm 12, and is provided with a ring 40 at its center beneath said arm. A tilting cord 41 is fixed to and depends from the ring 40. A ring 42 is mounted on the supporting arm 12 and short chains 43, 43*, are fixed to said ring and extend to the central portions of the braces 15, 16, to which they are attached.

The chains and ring serve as a stay and tend to keep the arm and frame straight and in the correct directions. A. yoke 44, of substantially U-shape, is fixed to and extends downward and forward from the cross-head 1.4 beneath the supporting arm 12. A sheave or pulley 45 is mounted in the carrier 10 to accommodate the rope (not shown) of the hay-fork or grapple, which rope for convenience should run through said carrier.

In practical use the device is positioned at the desired point in the length of the track 11 by manual operation of the cord 25 whereby the supporting arm 12 may be tilted to release the normal engagement of the braces 15, 16 and cross-bar 17 with the roof of the hay-barn. Then the U-shaped carrying frame 35 occupies an inclined. position, tilted forward toward the point from whence a fork or grapple (not shown) must approach with a portion of hay. The longitudinal tilting of the frame 35 is determined by engagement of the bight of the cord 39 with the supporting arm 12 (Fig. 2). The portion of hay is elevated and conveyed in any desired manner until it rides on the frame 35 and supporting arm 12 and, in reaching its seat thereon moves said frame into an approximately level position. Then the portion of hay is released. from the elevating-and-conveying means and rests, momentarily, on the frame 35 and supporting arm, having by impact therewith leveled said frame into the position shown by dotted lines in Fig. 2. Thereupon an operator grasps the cord 41 and moves the lower end portion of it to the rear and laterally until one or the other half portion of the cord 39 engages the yoke 44, dependent on which direction laterally it is desired to tilt the frame 35, and then applies draft thereto to the degree necessary to tilt said frame (and the shaft 32, arch 28 and boxes 26, 27) laterally against the resilience and leveling influence of the spring 34. The yoke 44 serves as a fulcrum, to which lateral strain is applied by the cord 39, and changes the direction of draft of said cord according to which side of the yoke is engaged thereby, to the end of tilting the frame 35 laterally. Such lateral tilting of the frame 35 de osits the portion of hay thereon to one side or the other of the median line of the mow or stack defined by the track 11. The

elevating-and-eonveyin means is then with drawn and reloaded and the frame 35 re-assumes its normal position in respect of lateral tilting by reason of the spring 34 and in respect of longitudinal tilting by gravity of its open end portion. As the mow is filled and the stack nears completion, the supporting arm 12 and. its carrier 10 are moved forward by manipulation of the cord 25.

I claim as my invention 1. In a hay-handling mechanism, a supporting arm, a frame mounted for longitudinal and lateral oscillation thereon, and yielding-pressure devices between said arm and frame tending against lateral oscillation of the frame.

shaft, a spring on said arm and engaging said shaft on opposite sides of said stopplate, and means for oscillating said frame laterally against the resilience of said spring.

4. In a hay-handling mechanism, a supporting arm, a cross-head thereon, a yoke mounted obliquely on said cross-head, a frame mounted for oscillation laterally and longitudinally on said arm, springs between.

said frame and arm, and a rope on said frame and cross-head and adapted to be brought into engagement with said yoke.

5. In a hay-handling mechanism, a supporting arm, a frame mounted for. oscillation on said arm, braces on said arm, a ring on said arm and flexible connections between. said ring and braces.

6. In a hay-handling mechanism, a supporting arm, a frame mounted for oscillation on said arm, a cross-head on said arm, braces on said cross-head, a ring on said arm, chains connecting said ring and braces, and a crossbar connecting said braces.
