Abstract
Abstract In accordance with the present invention there is provided a floor polisher or the like having a manipulating and carrying handle comprising a lower fork pivotally connected to the polisher base and an upper fork pivotally connected to the lower fork, there being releasable locking means for securing the forks in extended fixed position relative to each other. A shampoo tank is removably carried by the lower fork and is provided with a discharge valve having a valve stem extending from the upper end of the tank adjacent to the pivotal joint between the forks. Valve actuating mechanism is carried by the upper fork and is so arranged that when the forks are in extended locked position, the mechanism is in cooperative position with the valve stem for actuating the latter to open the valve. Conduit means extends from the discharge valve to the polisher base which includes a plurality of rotary brushes, at least one of which has an annular recess in which the conduit discharges. Each brush has a ring of sponge material, the rings of the different brushes being in compressive contact with each other. A channel is provided between the annular recess and the sponge on that brush.

Apparatus including a base member and a handle member connected with said base member, the improvement comprising in the handle member a lower fork connected with said base member, a yoke joining the ends of said lower fork remote from said base member, an upper fork pivotally conntected with said yoke at one end, a handle connected with the ends of said upper fork remote from said yoke, and means for releasably locking said forks in extended position; said releasable locking means including a channel in said yoke, a bar movably mounted in said channel, a pair of ears connected with said upper fork and coupled with said yoke, said ears having a curved surface extending into said channel and engaging said rod, an inclined surface coextensive with the said curved surface of said ears, said inclined surface and the adjacent surface of said channel defining a pair of wedge-shaped recesses for receiving said bar when said forks are in their extended position, means connected with said bar for moving said bar out of said recesses, a shampoo tank, means for removably securing said tank on said lower fork between the tines thereof; said tank having an outlet therein normally closed by valve means and a rod connected with the valve means and projecting from said tank at the upper end thereof adjacent to one tine of said lower fork, a motion translator in said yoke adapted to engage the projecting end of said tank valve rod; a lever adjacent to the handle of said upper fork, said lever being pivotally mounted on the tine of said upper rod coextensive with the one tine of said lower fork when said forks are extended, and a push rod movably connected with said coextensive tine engageable by said lever at one end and engaging said motion translator at its other end when said forks are in extended position, manipulation of said lever moving said push rod which in turn moves said motion translator to open the valve in said tank for discharge fluid shampoo from said tank.
