2 Claims.

The present invention relates to new and useful improvements in hay stackers and loaders, and has for its primary object to provide, in a manner as hereinafter set forth, an apparatus of this character which is adapted to be expeditiously mounted for operation on a conventional farm tractor and driven from the usual power take-off thereof without the necessity of making material structural alterations in said tractor.

Another very important object of the invention is to provide a stacker and loader of the aforementioned character which is adapted to lift the load and hold said load at any desired elevation while it is being transported to the' v apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

. Figure 9 is a view in side elevation of the hy- ,draulic brake-operating means.

Referring now to the drawings in detail, it will which has been illustrated comprises an elongated base structure of suitable material which is designated generally by reference character I. The base structure I includes side members 2 and front and rear cross members 3 and 4, respectively.

'The base structure I is adapted to be mounted,

longitudinally on a tractor 5. Toward this end, the cross member 3 is in the form of an' apertured plate which is bolted or otherwise firmly secured to the front end of the frame 6 of the tractor 5. The side members 2 of the base structure I rest at an intermediate point on the rear axle housings I of the tractor 5 and are secured thereon by U-bolts 8.

Mounted transversely on the base structure I rearwardly of the tractor 5 is a beam which is designated generally by reference character 9. The beam 9 includes spaced upper and lower bars ID with spacing blocks l l between the end portions thereof, between which bars the side members 2 of the base structure I pass. Substantially U-shaped brackets l2 are mounted on the end portions of the upper bar l0.

Arms l3 are pivotally mounted for vertical swinging movement on the brackets l2 and extend forwardly therefrom adjacent the rear wheels ll of the tractor 5. A cross member l5 extends between the forward end portions 'of the arms I3. Brace l6 are provided between the arms l3 and the cross member l5. A head I! is mounted for rocking adjustment on the forward end portions of the arms I3. The head II includes rake teeth IS, a back frame [9, braces 20, et cetera. The teeth l8 are fixed, at their rear end portions, on spaced, parallel bars 2| and 22. Substantially U-shaped brackets 23 on the bar 22 are ivotally mounted on the forward end portions of the arms l3 for vertical swinging movement. I

Mounted on the rear ends of the members 2 is a vertical frame structure 24 comprising uprights 25 and inclined braces 26 extending between saiduprights and said members 2. A cross bar 21 is mounted transversely on the I upper end portions of the uprights 25. Pulleys be seen that the embodiment of the invention 28 are mounted on the end portions of the cross bar 21. I

Rockably mounted larly extending arms 2!. Suitable cables or the like 30 are trained over the pulleys 28 and connected at one end to the arms 29 The cables II are connected at I2 to the upper portion of the back frame I! of the head H. A hand on the braces 26 is a transverse shaft 3| which terminates in right angulever 33 is fixed on the shaft 3|, said hand lever being operable from the drivers seat 34 of the tractor 5. Any suitable means may be provided for releasably securing the hand lever 33 in adjusted position.

- Mounted for vertical swinging movement at an intermediate point on the side members 2 of the base structure I is a yoke 35 which straddles the tractor 5. The yoke 35 has mounted thereon an inverted V 36. Forwardly diverging chains 3'! connect the V 36 to the forward end portions of the arms |3 for raising and lowering said arms with the head I! thereon.

Journaled longitudinally beneath the rear end portion of the base structure i is a drum 38. The drum 38 is fixed on a shaft 39. A hydraulic brake 4D is provided for the drum 38. The shaft 39 is driven from the usual power takeoff of the tractor 5 by means including a shaft 4| comprising a plurality of sections with suitable universal joints therebetween. The transmission 42 is provided between the shaft 39 and the shaft 4|, said transmission being operable from the seat 34 of the tractor 5.

Pulleys 43 and 44 are mounted, respectively, on the cross bar 21 and the V 36. A cable 45. is anchored at one end to the frame of the pulley 43. The cable 45 extends forwardly around the pulley 44, back over the pulley 43 and is secured at its other end to the drum 38 for winding thereon. A guide pulley 48 is provided for the cable 45 on the frame 24 above the drum'38.

The brake 4|] receives fluid from a cylinder 41 see Figure 9). A hand lever 48, operable from the driver's seat 34 of the tractor 5, is connected by means including a rod 49 to the usual piston in the fluid cylinder 41.

It is thought that the operation of the apparatus will be readily apparent from a consideration of the foregoing. Briefly, to load the device, the arms l3 are swung downwardly and the head I! is swung to the full line position of Figure 1 of the drawings through the medium of the hand lever 33. Of course, the tractor 5 is driven forwardly for scooping the hay from the ground onto the head When a load has thus been gathered, the lever 33 is swung forwardly for swinging the head I! upwardly to the dotted line position of Figure 1 of the drawings for retaining the hay on said head. The brake 40 is then released and the transmission 42 is placed in gear for actuating the drum 38 from the power takeoff of the tractor 5 in a manner to wind the cable 45 on said drum. Thus, the arms l3 with the head I! thereon are swung upwardly to elevated position. When' the desired elevation has been reached, the transmission is again put in neutral and the brake 40 is applied for securing the drum 33 against rotation thereby retaining the load in raised position. The hay may then be transported to any desired location. When the location at which the hay is to be discharged is reached, the lever 33 is swung rearwardly for permitting the head H to swing downwardly, by gravity, thereby dumping the hay.

It is believed that the many advantages of a tractor-mounted hay stacker and loader constr'ucted in accordance with the present invention will be readily understood, and although a preferred embodiment of the apparatus is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

1. In a hay loader and stacker, a base struc ture comprising a horizontal rectangular frame having a front cross-member apertured for rigid bolting to the front end of a tractor frame and side members of a length to extend across and rearwardly beyond the rear axle housings of the tractor at opposite sides of the latter, means to rigidly bolt said side members on said rear axle housings, a transverse beamcarried by the rear portion of said base structure and projecting laterally beyond opposite sides of the latter, arms pivoted at their rear ends to the ends of said beam for vertical swinging movement in planes outwardly of the traction wheels of the tractor, said arms extending forwardly beyond the front of said base structure, a buck rake pivoted for vertical tilting movement on the forward ends of said arms, a vertical frame rigid with and rising from the rear end of said base structure, guides carried by the top of said vertical frame, a transverse rock shaft Journaled above the base structure directly in front of said vertical frame and having crank arms, a cable attached to the back of the rake and extending rearwardly over said guides and then forwardly and attached to said crank arms, a lever for rocking said rock shaft to tilt the rake relative to said arms, and power-operated means to vertically swing said arms to raise the rake.
