Abstract: This disclosure is directed to the use of an adjustable hand tool which employs means to prevent the separation of the cross members. Specifically the invention uses an arcquate circular cross section rib which selectively engages one of several arcquate circular cross sectioned grooves. The pliers further have a pin with a cap at one end and externally threaded at the other. The pin has internal threads with a securing screw threadably mounted therein. A threaded cap is threadably attached to the pin and the securing screw tightened against the cap to cause it to remain in its selected position.

Abstract: The lift is installed under the cargo floor proximate to the side door of the van. In the retracted position it is entirely concealed and does not obstruct the normal van usage. Stationary track members are attached to the van. Slidably mounted within the track members are frame members which may be extended or retracted from the van by use of a pair of worm gears. A pair of hydraulic cylinders interconnect the platform and the frame using four links which raise and lower the platform equalangularly. The equalangular motion of the links maintains the platform in a substantially horizontal position as it is lowered from its raised position level with the floor of the van to its lower position with the street or sidewalk.

Abstract: A planar element storage and display apparatus is provided having an outer box and a carriage slidably mounted therein. The carriage can be pulled from the outer box and a stack of planar elements such as photographs can be placed face up therein. The carriage box is provided with a display window for viewing the upper most element when the carriage carrying the stack of photographs is pushed into the outer box. The outer box is equipped with a detaching means which holds the upper most element and separates it from the stack when the carriage is withdrawn from the outer box. When the carriage is pulled out of the outer box, the upper most element is separated from the stack and drops to the floor of the outer box. Means is provided for placing the dropped element on the bottom of the stack when the carriage is pushed back into the outer box.
