Apparatus for handling a large hay bale
First Claim
1. A bale handling machine comprising:
- a. a portable frame,b. a bale receiving unit having fork members,c. means movably supporting said bale receiving unit on the portable frame for movement from a ground lowered bale loading position, wherein said fork members are extended horizontally rearwardly, to an elevated bale transport position, wherein the fork members are projected upwardly and rearwardly,d. holding means on said portable frame releasably interlocked with said bale receiving unit supporting means to hold said bale receiving unit in the transport position therefor,e. manually actuated means on said portable frame for operating said releasable holding means to release said bale receiving unit supporting means for movement to a bale loading position for said bale receiving unit,f. said portable frame, when the bale receiving unit is in the loading position therefor, being movable rearwardly relative to a ground supported bale to load the bale on the receiving unit, andg. means responsive to a forward advance of the portable frame, including a ground engageable lever means movably supported on the bale receiving unit and a lift lever means interconnecting said portable frame and bale receiving unit supporting means, for elevating the bale receiving unit to the transport position therefor.

Abstract
The apparatus of this invention is capable of handling large bales of hay weighing fifteen hundred pounds or more without requiring the use of hydraulic, electrical or any other special source of power. The apparatus includes a portable frame connectable to a tractor and a hay buck or fork unit carried on a lift frame assembly which is movably supported on the portable frame to provide for a movement of the fork unit between a lowered bale loading position and a bale transport position. The fork unit is movable by gravity from the transport position to the bale loading position therefor, wherein the bale is loaded by a rearward movement of the portable frame relative to such bale. As the bale approaches a fully carried position on the fork unit, a leverage means is automatically actuated to elevate the lift frame assembly to a transport position in response to a forward advance of the portable frame. When the fork unit reaches the transport position the lift frame assembly is automatically locked against movement to a bale loading position for the fork unit.

5. A bale handling machine comprising:
-
a. a portable frame connectable to a vehicle, b. a fork unit, c. a frame assembly for supporting said fork unit, d. means movably mounting said frame assembly on the portable frame for movement of the fork unit from a lowered ground loading position to an elevated transport position, said portable frame, when the fork unit is in the lowered position therefor, being moved rearwardly relative to a ground supported bale to load a bale on the fork unit, e. manually actuated means on the portable frame for releasably holding the frame assembly in a transport position for the fork unit, f. means for moving said frame assembly from the loading position of the fork unit to the transport position therefor in response to a forward advance of said portable frame including a lift lever means and a ground engaging lever means, g. means movably interconnecting said lift lever means with said portable frame and frame assembly, h. means movably supporting said ground engaging lever means on said fork unit for movement into and out of ground engagement, i. means on said frame assembly for releasably holding said ground engaging lever means out of ground engagement, when the fork unit is in the transport position therefor, and actuated to drop said ground engaging lever means into ground engagement when a bale is located on said fork unit, and j. means coacting with said releasable holding means to automatically move said holding means into holding engagement with said ground engaging lever means concurrently with the elevation of the fork unit to the transport position therefor. - View Dependent Claims (6, 7, 8, 9)
