Abstract: In a fork lift truck having a pair of spaced apart forwardly extending tines which are movable vertically relative to the truck to effect a raising or lowering of loads thereon. Each of the tines is provided with a sleeve which is telescopically slidable thereover. A cross member joins the sleeves at their inner ends closest to the truck. A mechanical linkage is mounted on the truck and attached to the cross member. The linkage is arranged and constructed in one position thereof to provide that the fork tines and their covering sleeves are substantially coextensive and in another position thereof to provide that the covering sleeves are forwardly extended relative to the tines on which they slide. This causes the covering sleeves to be tine extensions thus permitting a load carried thereon to be forwardly extended relative to the lift truck.

Abstract: A tricycle type vehicle with two forwardly disposed spaced apart drive wheels and a rear centrally disposed caster wheel. Spaced apart auxiliary drive wheels flank both sides of the rear caster wheel and are arranged for vertical movement on the vehicle. The auxiliary drive wheels may be in an up inoperative position to permit the vehicle to act solely as a tricycle with two driving wheels, or down in ground engaging operative position causing the caster wheel to be raised off the ground and thus converting the vehicle to a four wheel drive vehicle.

Abstract: Each of the tines of a fork lift truck is provided with a sleeve which is telescopically slidable thereover. A cross member joins the sleeves at their inner ends closest to the truck. A mechanical linkage is mounted on the truck and attached to the cross member. Extension of the linkage causes the covering sleeves to be tine extensions thus permitting a load carried thereon to be forwardly extended relative to the lift truck. A bail member having a rectangular perimeter is pivotally mounted at its rear on the lift truck to the rear of the tines and is positionable either in a substantially vertical position adjacent the front of the lift truck or in a horizontal position where the front cross member rests on the top surface of the sleeves. A cross slatted pallet carrying a load is positioned across the forwardly extending tines with their sleeve covers. Each of the sleeves is provided with a fixed lug on its top side.
