bifurcated support 17 a second axle 21 pivotally mounts a drive link 22 at a first end of the drive link to the second axle 21 within the pivot boss 19 the drive link second end includes a piston 23 mounted thereto about a third axle 25 with the bifurcated piston rod 24 mounted to a piston 23 medially thereof a receiving container 26 is provided having a container floor 32 see fig4 with the container floor having container floor apertures 33 for drainage a support plate 27 is fixedly mounted to the front wall 12 in adjacency to the bottom wall 16 having a support plate cylindrical recess 27a for positioning the receiving container 26 coaxially aligned with the piston 23 the recess includes a matrix of drain apertures 28 therethrough in this manner a chamois member is merely positioned within the container 26 the articulated linkage to include the actuator lever 18 the drive link 22 and the piston 23 captures the chamois between the piston 23 and the container floor 32 to direct excess fluid from the chamois through the drain apertures 28 as well as the container floor apertures 33 the recess 27a removably mounts the container and the structures aligns such the base plate 11 is mounted to a vertical wall surface the fig3 indicates the use of spaced side wall mounting bores 29 directed into each of the side walls in a coaxially aligned relationship relative to one another such that as illustrated in fig3 a support clamp 30 having spring biased facing jaws includes a mounting rod 31 that in turn is received within.
