Abstract
Abstract My dump-truck Tail Gate Spread Chain Release has oppositely spaced bearing members mounted to the dump-truck tail gate adjacent the bottom edge thereof. A chain release holding and release toggle member is pivotably mounted between said spaced bearing members. I fasten a cantilevered arm to said pivotable member, extending upwardly therefrom and fastened fixedly but removably to said truck tail gate. The chain is held in a slotted opening in said pivotable member at selective spaced intervals so that the tail gate may be adjusted to any desired position for allowing materials therein to fall from the truck body. When it is desired to release the chain from the weight of the tail gate and materials in the truck, the cantilevered arm is released from the upper portion of the end gate and the pivotable chain holding member is then pivoted downwardly from dead center in the direction of the pull of said chain, allowing said chain to be easily removed from said slotted opening.

A truck tail gate holding and releasing apparatus comprising a tail gate holder means including a pivotable member having a slot therein pivotably mounted on said tail gate; a tail gate chain adapted to be fastened to the bed of a truck having a link thereof placed in said slot for securing said tail gate; an elongated cantilevered arm connected to said pivotable member including an extended portion for actuating said pivotable member; and latch means mounted on said gate for releasably securing said arm to said gate by said arm extended portion.
Claim 3
Dependent Claim
21 words
The truck tail gate holding and releasing apparatus of claim 1, further comprising bracket means for pivotably mounting said pivotable member.
Claim 4
Dependent Claim
161 words
A tail gate controlling apparatus for a vehicle dump-body comprising a pivotable holder means mounted on said tail gate having a slot therein and a cantilevered arm extending outwardly therefrom, a portion of said slot being sized to admit the thickness of a chain link but sized less than the width of a link to prevent passage therethrough of a link positioned transverse to the slot; a tail gate mounted on said dump-body and a spreader chain associated with said gate; gate release means on said body and normally holding a lower portion of said gate closed against said body, a portion of said chain being affixed to said body beneath said tail gate, and a link of said chain being received and retained in said portion of said slot; and latch means mounted on said tail gate above said pivotable holder means for retaining said cantilevered arm in juxtaposition with said tailgate and for maintaining tension between the chain links.
