Abstract
Abstract This invention relates to an actuator for a compacting blade for a refuse body. Novel scissors types of linkage mechanism are driven by a double acting cylinder to amplify the stroke so that there is a working stroke greater than the piston travel of the actuating cylinder.

Claim 1
Independent Claim
139 words
In a body having a compacting blade longitudinally movable between a front end and a rear end of the body, apparatus for reciprocally moving the blade comprising: scissors linkage means including a first link pivotally connected at one end to the front of the body, and a second link pivotally connected at one end to the base of the blade, said links pivotally connected together at their free ends for articulated movement longitudinally of the body; and power multiplying means including a double-acting hydraulic piston and cylinder device, with one end of the device pivotally connected to said first link, and with the other end of the device pivotally connected to said second link, whereby operation of said device results in articulation of said linkage means to move the blade in one direction or the other within the body.
