Abstract: A rotary clutch shaft of a floor machine removeably receives and rotates a brush block having downwardly protruding circumferentially arranged brushes protruding from the periphery of the brush block. Hooks which protrude from the bottom of the block, removeably retains a reversible, tufted, resilient, absorbent bonnet confined within the brushes and a frictional drive on the brush block engages the upper surface of the bonnet and rotates the bonnet as the block is rotated. The bonnet is readily removeable and can be laundered and reinstalled.

Abstract: A translucent tank carries along its bottom portion, a pair of transversely extending spaced parallel wick pads which are removeably received in and protrude from recesses in the bottom portion. A handle is pivotally connected along one side of the tank and has control button, both of which control a spring loaded dispensing bar on which are carried resilient valve members which close and open discharge tubes of the tank. A drain tube can empty the contents of the tank to discharge liquid in front of the wick pads. A kick bar releases latches which hold the handle in a transport position with respect to tank. Wheels at the front of the tank permit the handle to tilt the tank for transporting from place to place.

Abstract: A yarn produced from two or more twisted cellulosic fibers, such as cotton or cotton rayon fibers, the plies being helically wound around a thermoplastic filament core which is subsequently melted to bind the inner portions of the yarn together so that it does not untwist or shed lint readily. The yarn is employed in a dust mop or floor mat for a shampoo bonnett for stain resistant treated carpet.
