In a spring loaded material dispenser which is adapted to automatically ascend and descend as material is removed and added thereto, said dispenser including a vertically movable table suspended off the lower ends of a series of elongated tension springs, the upper ends of said springs being connected to a spring hanger, and manual means for lowering said hanger from a raised spring tensioned position to a spring de-tensioned position thereby lowering the table to a fixed loading position and for raising said hanger to tension said springs thereby urging said table to move vertically as material is removed and added thereto.
A material dispenser comprising an L-shaped frame, a movable L-shaped carriage on said frame, the upright of said carriage being operable up and down in the upright of said frame and said carriage base being adapted to bottom on the base of said frame, a series of elongated tension springs in said frame upright, a hoist in the upper end of said frame, the upper ends of said springs being connected to a spring hanger and a cable extending from said hoist to said hanger, and manual means on said frame to raise said cable to raise said hanger to tension said springs whereby said carriage is suspended off said springs and to lower said cable to lower said hanger to bottom said carriage base on said frame base.
In a material dispenser comprising a frame and a carriage movably mounted therein from a raised position to a bottomed position, a series of elongated coil springs having one of their ends connected to said carriage, a single manually movable means connected to the other ends of said springs to stretch the same whereby said carriage is suspended in said frame off said springs to automatically move vertically when articles are added and removed, and said same means being operable in an opposite sense to collapse said springs to return said carriage to said bottomed position in said frame to a fixed carriage loading position.
