Abstract
Abstract A retriever clamping device for attachment onto a bale wagon for providing the same with the additional capability of retrieving load stacks. The clamping device is generally T-shaped and includes an elongated beam having a cross bar attached thereto about the upper portions and extending laterally thereacross. A series of spaced apart tines are disposed on the cross bar and extend rearwardly for engagement with the top tier of the load stack to be retrieved. The T-shaped clamping device is pivotally mounted transversely the forward end of a load table by securing a mounting bar that is affixed to the clamp within mounted brackets extending from the load table. The clamp is actuated by a remotely controlled hydraulic cylinder whose piston is connected to the lower portion of the elongated beam.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
187 words
In a bale wagon having a wheel mounted chassis adapted to be propelled forwardly over a field, a first receiving table pivotally mounted on said chassis, a second transfer table pivotally mounted on said chassis, and a third load carrying table pivotally mounted on said chassis, said tables being tandemly arrangEd whereby said first and second tables cooperate to form a load stack on said third table and wherein said third table includes upstanding retaining means about the rear thereof and is pivotally moveable from a generally horizontal loading position to a position generally normal with respect to said chassis for stacking said load stack, the improvement comprising retriever means mounted on said third table for engagement and disengagement with the upper portion of said load stack, and biasing means for selectively maintaining said retriever means in engagement with an end portion of the stack opposite said retaining means, whereby said third table may additionally be employed to retrieve load stacks by tilting said third table, positioning said retaining means beneath said load stack and engaging said retriever means with the upper portion of said load stack.
Claim 2
Dependent Claim
187 words
In a bale wagon having a wheel mounted chassis adapted to be propelled forwardly over a field, a first receiving table pivotally mounted on said chassis, a second transfer table pivotally mounted on said chassis, and a third load carrying table pivotally mounted on said chassis, said tables being tandemly arrangEd whereby said first and second tables cooperate to form a load stack on said third table and wherein said third table includes upstanding retaining means about the rear thereof and is pivotally moveable from a generally horizontal loading position to a position generally normal with respect to said chassis for stacking said load stack, the improvement comprising retriever means mounted on said third table for engagement and disengagement with the upper portion of said load stack, and biasing means for selectively maintaining said retriever means in engagement with an end portion of the stack opposite said retaining means, whereby said third table may additionally be employed to retrieve load stacks by tilting said third table, positioning said retaining means beneath said load stack and engaging said retriever means with the upper portion of said load stack.
Claim 3
Dependent Claim
57 words
A bale wagon, as recited in claim 1 wherein said retriever means is pivotally mounted to the front portion of said third table and wherein said retriever means is actuated into and out of engagement with said load stack by a remotely controlled hydraulic cylinder extending from said third table and operatively connected to said retriever means.
Claim 4
Dependent Claim
57 words
A bale wagon as recited in claim 2 wherein said retriever means includes a clamp structure having an elongated body member with a cross bar mounted transversely about the upper portion thereof, said cross bar having a plurality of engaging elements extending therefrom toward the rear of said third table for positive engagement with said load stack.
Claim 5
Dependent Claim
125 words
A bale wagon for loading individual bales of hay onto a load table to form a load stack, stacking the load in a selected stacking area, and retrieving the same load stacks, comprising the combination of: a wheel mounted chassis structure; a first receiving table, a second transfer table, and a third load carrying table having retaining means disposed about the rear thereof, said tables being tandemly arranged and each of said tables being pivotally mounted transversely on said chassis; a detachable retriever clamp pivotally mounted transversely on the forward portion of said third table; and a remotely controlled hydraulic cylinder extending from said third table operatively connected to said retriever clamp for actuating the same into and out of engagement with said load stack.
Claim 6
Dependent Claim
125 words
A bale wagon for loading individual bales of hay onto a load table to form a load stack, stacking the load in a selected stacking area, and retrieving the same load stacks, comprising the combination of: a wheel mounted chassis structure; a first receiving table, a second transfer table, and a third load carrying table having retaining means disposed about the rear thereof, said tables being tandemly arranged and each of said tables being pivotally mounted transversely on said chassis; a detachable retriever clamp pivotally mounted transversely on the forward portion of said third table; and a remotely controlled hydraulic cylinder extending from said third table operatively connected to said retriever clamp for actuating the same into and out of engagement with said load stack.
Claim 7
Dependent Claim
58 words
A bale wagon as recited in claim 4 wherein said retriever clamp includes an elongated beam member having a cross bar fixed about the upper portion thereof and extending laterally thereacross, said cross are includes a plurality of engaging elements extending therefrom toward the rear of said third table for positive engagement with said load stack during retrieving.
Claim 8
Dependent Claim
58 words
A bale wagon as recited in claim 5, wherein said beam includes a first upper sectional member and a second lower sectional member pivotally secured together in end to end relationship and wherein a biasing means is secured to the inner end of one of said sectional members and extends over for engagement with other said sectional member.
Claim 9
Dependent Claim
19 words
A bale wagon as recited in claim 6 wherein said elongated beam is telescopical for adjusting the length thereof.
Claim 10
Dependent Claim
28 words
A bale wagon as recited in claim 6 wherein said biasing means includes a leaf spring extending across the inner ends of said first and second sectional member.
