Abstract

A sturdy box capable of supporting a heavy industrial battery, weighing several hundred pounds, carries on each lateral side an elongated fore and aft housing defining a channel within which is vertically movable an elongated fore and aft carriage. The carriage includes a plurality of rollers engageable with a supporting surface. The rollers are capable of lifting the box by reactive force when the carriage is urged downwardly by a pair of eccentric cams journaled in the housing and engaging the top of the carriage. A hand operated lever actuates the cams and a pawl and ratchet tooth selectively locks the lowered carriage in boxsupporting position so that the battery can be moved to the desired location. The battery box is immobilized as the carriage is retracted upwardly and the bottom of the box engages the supporting surface.

Claims

1. A battery truck comprising:

a. a box including a pair of end walls, a pair of fore and aft side walls, and a bottom capable of supporting a battery;

b. an elongated, fore and aft housing mounted on each of said side walls, each of said housings including an elongated fore and aft side plate spaced from the adjacent one of said pair of side walls to define therewith an elongated, fore and aft channel;

c. an elongated, fore and aft carriage vertically movable in each of said channels between a first retracted position and a second projected position, each of said carriages including at least two rollers on said carriage in fore and aft alignment, the bottom of said rollers extending below said housing and said box in said second position of said carriage;

d. at least two eccentric cams rockably mounted on each of said housings in fore and aft alignment and in operating engagement with the top of the underlying one of said carriages; and

, e. lever means connecting each of said pair of cams for selectively urging said cams downwardly against said carriage to an extent sufficient to move said carriage from said first position to said second position, thereby elevating said box above a supporting surface by reactive force exerted by said rollers in engagement with the supporting surface upwardly against said carriage, said pair of cams, said housing and said box.

2. A battery truck as in claim 1 including pawl and ratchet means associated with said lever means and said cams for selectively locking said carriage in said second position.

3. A battery truck as in claim 1 further including limit stop means carried on said housing for limiting the extent of downward movement of said carriage relative to said housing.
