Abstract
Abstract A load handling attachment for the vertically adjustable support unit of a lift truck. The attachment includes a vertical positioning plate horizontally adjustable forwardly and rearwardly in overlying relation to the platens by a pantograph mechanism or the like. The positioning plate mounts a vertically adjustable carton cap engaging blade for a gripping interlocking with the load and a locking of the load to the positioning plate for a manipulation of the load in conjunction with the positioning plate relative to the lifting platens.

Claim 1
Independent Claim
207 words
Load handling apparatus for a vertically adjustable lift truck support unit including a rear truck engaging portion and horizontal support means projecting forwardly therefrom and terminating in a forward edge selectively introducible beneath a load to be supported; said apparatus comprising a positioning panel overlying said horizontal support means and projecting vertically thereabove; means mounting said positioning panel for horizontal movement over said support means between a first forward position adjacent the forward edge and a second position sufficiently rearward of the forward edge to accomodate a load on the horizontal support means between the positioning panel and the forward edge; power means for effecting movement of the positioning panel between the first and second positions thereof; load engaging means on said positioning panel selectively engageable with a load for a controlled movement of a load with the positioning panel relative to the horizontal support means; means for effecting a vertical adjustment Of the load engaging means relative to the positioning panel; and said load engaging means having an upwardly directed blade engageable beneath a top cap upon vertical adjustment of said blade whereby the carton can be both gripped and upwardly tipped and the load can be selectively drawn onto and pushed from the support means.
Claim 2
Dependent Claim
207 words
Load handling apparatus for a vertically adjustable lift truck support unit including a rear truck engaging portion and horizontal support means projecting forwardly therefrom and terminating in a forward edge selectively introducible beneath a load to be supported; said apparatus comprising a positioning panel overlying said horizontal support means and projecting vertically thereabove; means mounting said positioning panel for horizontal movement over said support means between a first forward position adjacent the forward edge and a second position sufficiently rearward of the forward edge to accomodate a load on the horizontal support means between the positioning panel and the forward edge; power means for effecting movement of the positioning panel between the first and second positions thereof; load engaging means on said positioning panel selectively engageable with a load for a controlled movement of a load with the positioning panel relative to the horizontal support means; means for effecting a vertical adjustment Of the load engaging means relative to the positioning panel; and said load engaging means having an upwardly directed blade engageable beneath a top cap upon vertical adjustment of said blade whereby the carton can be both gripped and upwardly tipped and the load can be selectively drawn onto and pushed from the support means.
Claim 3
Dependent Claim
34 words

Claim 4
Dependent Claim
45 words
The apparatus of claim 1 including a second upwardly directed blade mounted on said positioning panel in vertically spaced relation to said first mentioned blade for the accommodation of a second carton in stacked relation to a first carton engageable by the first mentioned blade.
Claim 5
Dependent Claim
210 words
Load handling apparatus for a vertically adjustable lift truck support unit including a rear truck engaging portion and horizontal support means projecting forwardly therefrom and terminating in a forward edge selectively introducible beneath a load to be supported; said apparatus comprising a positioning panel overlying said horizontal support means and projecting vertically thereabove; means mounting said positioning panel for horizontal movement over said support means between a first forward position adjacent the forward edge and a second position sufficiently rearward of the forward edge to accommodate a load on the horizontal support means between the positioning panel and the forward edge; power means for effecting movement of the positioning panel between the first and second positions thereof; load engaging means on said positioning panel selectively engageable with a load for a controlled movement of a load with the positioning panel relative to the horizontal support means; means for effecting a vertical adjustment of the load engaging means relative to the postioning panel; and said load engaging means having a downwardly directed blade engageable with a bottom cap to permit a carton to be gripped and laterally moved in conjunction with the movement of the positioning panel, whereby the load can be selectively drawn onto and pushed from the support means.
Claim 6
Dependent Claim
210 words
Load handling apparatus for a vertically adjustable lift truck support unit including a rear truck engaging portion and horizontal support means projecting forwardly therefrom and terminating in a forward edge selectively introducible beneath a load to be supported; said apparatus comprising a positioning panel overlying said horizontal support means and projecting vertically thereabove; means mounting said positioning panel for horizontal movement over said support means between a first forward position adjacent the forward edge and a second position sufficiently rearward of the forward edge to accommodate a load on the horizontal support means between the positioning panel and the forward edge; power means for effecting movement of the positioning panel between the first and second positions thereof; load engaging means on said positioning panel selectively engageable with a load for a controlled movement of a load with the positioning panel relative to the horizontal support means; means for effecting a vertical adjustment of the load engaging means relative to the postioning panel; and said load engaging means having a downwardly directed blade engageable with a bottom cap to permit a carton to be gripped and laterally moved in conjunction with the movement of the positioning panel, whereby the load can be selectively drawn onto and pushed from the support means.
