Abstract
Abstract A hay handling device is mounted in a vehicle bed to load, carry, and unload large hay bales. A rugged frame of the device is securely held in the vehicle bed by brackets which release the frame in selective fashion to permit its removal. A horizontal support member which is pivoted to the frame carries a central spear which is adapted to penetrate a bale resting on the ground. The spear is secured to a small sleeve which is slidably mounted on an upright post so that the elevation of the spear can be adjusted in order to accommodate bales of various sizes and vehicle beds of different heights. Shorter spears are located on opposite sides of the central spear to cooperate in handling the hay bale. A power winch operates on the upright post to pivot the support member in a manner to raise a bale which the spears have penetrated.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
168 words
Apparatus for handling a large bale of hay, said apparatus comprising: a support member adapted to be coupled with a vehicle for pivotal movement about a generally horizontal pivot axis; a substantially upright post structure coupled with said support member for movement therewith about said pivot axis; a sleeve member mounted on said post structure for up and down sliding movement thereon between a plurality of spaced apart positions without removing said sleeve member from the post structure; means for releasably securing said sleeve member at each of said spaced apart positions on said post structure; a spear member for piercing a hay bale, said spear member being rigidly coupled with said sleeve member to move with said support member and post structure in a manner to raise and lower the bale in response to pivoting of said support member about its pivot axis; and power means for pivoting said support member about its pivot axis in a direction to raise the bale from the ground for transport.
Claim 2
Dependent Claim
168 words
Apparatus for handling a large bale of hay, said apparatus comprising: a support member adapted to be coupled with a vehicle for pivotal movement about a generally horizontal pivot axis; a substantially upright post structure coupled with said support member for movement therewith about said pivot axis; a sleeve member mounted on said post structure for up and down sliding movement thereon between a plurality of spaced apart positions without removing said sleeve member from the post structure; means for releasably securing said sleeve member at each of said spaced apart positions on said post structure; a spear member for piercing a hay bale, said spear member being rigidly coupled with said sleeve member to move with said support member and post structure in a manner to raise and lower the bale in response to pivoting of said support member about its pivot axis; and power means for pivoting said support member about its pivot axis in a direction to raise the bale from the ground for transport.
Claim 3
Dependent Claim
43 words
Apparatus as set forth in claim 1, including second and third spear members for piercing the bale coupled with said support member on opposite sides of the first mentioned spear member and movable with said support member to assist in raising the bale.
Claim 4
Dependent Claim
58 words
Apparatus as set forth in claim 1, wherein: said support member is oriented substantially horizontally; said sleeve member includes a downward extension which lies directly against said support member when said sleeve member is at a preselected position alone said post structure; and said spear member is rigidly carried directly on said extension to project generally rearwardly therefrom.
Claim 5
Dependent Claim
178 words
Hay bale handling apparatus as set forth in claim 1, further adapted for removable installation in a vheicle bed having a generally rearwardly facing surface at the rear end thereof, said apparatus comprising: a rigid frame adapted for removable installation in the vehicle bed and including a first frame member engageable with said surface in a manner to prevent forward sliding of said frame in the vehicle bed; a second rigid frame member rigidly coupled with said first frame member and adapted to lie on the vehicle bed at a location forwardly of the first member; at least one bracket mounted on the vehicle bed and having a first portion extending upwardly therefrom and a second portion spaced above the bed to cooperate with said first portion to present a forwardly opening space for receiving said second frame member, said second portion overlying said second frame member when same is received in said space, and said first portion preventing rearward sliding of said frame in the vehicle bed, whereby said frame is releasably secured on the vehicle bed.
