摘要：An upwardly opening tank including opposite ends and a pair of upright

standards supported and projecting upwardly from opposite end portions of the bottomwall of the tank disposed along the longitudinal centerline of the tank. A horizontal rackis supported within the tank and includes upstanding downwardly opening guide tubestelescopingly engaged with the standards. The upper ends of the guide tubes includelaterally outwardly offset and depending support arms disposed outwardly of verticaltransverse planes containing the end walls of the tank and a pair of horizontal

longitudinally extending operating shafts are journaled beneath the bottom wall of thetank on opposite sides of the longitudinal centerline thereof. A pair of upstandingcrossed levers are secured to each pair of corresponding ends of the operating shaftsand the upper ends of each pair of crossed levers are connected to the lower ends of thecorresponding support arms of the guide tubes by means of a pair of links having onepair of lower ends pivotally connected to the upper ends of the levers and the other pairof upper ends thereof pivotally connected to the support arms. Also, one pair of

corresponding ends of the shafts include crank arms carried thereby and the remote endportions of the cylinder and piston rod of a fluid cylinder are pivotally connected to thefree ends of the crank arms in a manner such that expansion of the fluid cylinder causes

the upper ends of the crossed levers to be swung toward each other and contraction ofthe cylinder causes the upper ends of the crossed levers to swing apart, thereby raisingthe guide tubes or sleeves when the fluid cylinder is extended and lowering the guidetubes and rack supported therefrom when the fluid cylinder is contracted.
