Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
195 words
A bale stack transporting vehicle having a lifting fork comprising a back frame and a number of parallel fork tines extending perpendicular to the plane of said frame from adjacent the lower edge thereof, said fork being mounted on said vehicle for a. guided upward load-lifting movement with the plane of said back frame substantially vertical, and b. tilting movement about a transverse axis to incline said back frame away from its vertical alignment and raise the tips of the tines, thus cradling a load between said tines and said back frame, means mounting said tines on said back frame which includes an adjustment mechanism by means of which transverse adjustment may be made of the position of the tips of the tines relative to the back frame, each tine being of inverted T cross-section and pivotally mounted through the upright web thereof, the adjustment mechanism comprising set screws acting against the upright web of each tine, and a pair of laterally movable gates, one on either side of said fork, with drive means coupled to said gates to move them into contact with a load to retain it securely in position on said tines.
Claim 2
Dependent Claim
195 words
A bale stack transporting vehicle having a lifting fork comprising a back frame and a number of parallel fork tines extending perpendicular to the plane of said frame from adjacent the lower edge thereof, said fork being mounted on said vehicle for a. guided upward load-lifting movement with the plane of said back frame substantially vertical, and b. tilting movement about a transverse axis to incline said back frame away from its vertical alignment and raise the tips of the tines, thus cradling a load between said tines and said back frame, means mounting said tines on said back frame which includes an adjustment mechanism by means of which transverse adjustment may be made of the position of the tips of the tines relative to the back frame, each tine being of inverted T cross-section and pivotally mounted through the upright web thereof, the adjustment mechanism comprising set screws acting against the upright web of each tine, and a pair of laterally movable gates, one on either side of said fork, with drive means coupled to said gates to move them into contact with a load to retain it securely in position on said tines.
Claim 3
Dependent Claim
41 words
A fork-lift wheeled vehicle according to claim 1 which includes a stationary guard frame which, when the fork is in its tilted position, cooperates with the back frame and the tines to form a container for a load on the fork.
Claim 4
Dependent Claim
42 words
A vehicle according to claim 2 wherein the fork is provided with a stop for limiting the tilting of the fork, the guard frame being so inclined as to extend parallel to the tines when the fork is tilted to its limit.
