Abstract: A side shifter mountable on a conventional hook-type lift truck carriage. The shifter includes an upper hook which, through removable wear shoes, accommodates a sliding engagement between the shifter and the upper bar in such a carriage, and a rotary spherical-segment bearing disposed below the hook which accommodates a rolling point contact with the lower bar in such a carriage.

Abstract: A paper roll-handling clamp for lift trucks of the pivoted arm type capable of clamping a paper roll and shifting the position of the roll relative to the lift truck between a position of equal extension, wherein the forward ends of the clamp arms extend a substantially equal distance forwardly of the lift truck, and a position of unequal extension wherein the forward end of one clamp arm extends a greater distance forwardly than the forward end of the other clamp arm. The shifting movement of the clamp arms in unison occurs about a first transverse pivot axis, while the pivoting of the clamp arms with respect to one another to perform the clamping function occurs about a second transverse pivot axis located a spaced distance away from the first pivot axis and movable with respect thereto.

Abstract: A single-acting, three-stage, four-section telescopic ram for use in conjunction with a triple-lift type mast in a lift truck. The ram features an extremely low overall length when fully contracted, thus affording good operator visibility. The ram also is capable of producing surprisingly "high-lift" despite its low contracted profile. Further, the ram features an internal construction that produces constant lifting and lowering speeds for a load, as well as providing for positive control over the sequence of movements of parts in and on an associated mast.
