The rings I3 .are thus yieldable in direction.radially of each ofisaid rings. .Z'I'h'e rollers l4 and i5 and Icaster. l6. providev forportability of the rug .or. carpet cleaner while the screw l1, screw threaded in the. rearwardly ex- ..tending .boss lb. of. the. frame l provides for ,the

"This castefbaseilB is, a resilient plate adapted to-be deflected ,by downward extensionof. the end I'la of the, screw I! bearing'on the uppersurface of saidoaster base l8. Vertical adjustment ofthe. rear end of the frame I tendsItoadjust the spaced relationship of the shaftsf'li, :9,and l0 froml'the rug A when rotating.

The operation of my rug and carpet cleaner is substantially as follows:

When the motor 2 is rotating the shaft 3, the pulleys 5 and 6 engaged by the belt I drive the 3 shaft 20 which rotates the shaft end plate II engaging the beater shafts 8, 9 .and II] which are secured to the shaft end plate I2 at their opposite ends and this shaft end plate I2 is secured to the shaft 20 journaled in the casing l as hereinbefore described. As the beater shafts -8, 9 and I rotate about the axis of the shaft 20, the rings I3 are centrifugally extended and engage the upper surface of the rug A in their side to side relationship to each other. These rings I3 are resilient rings and provide a rolling and beating motion at the upper surface of a carpet or rug which very efficiently removes the dust and foreign matter from the nap of the rug or carpet as the case may be. It will be here noted that the rings I3, due to their flexible and resilient character, and due. to their loosely supported condition, operate as flippers, providing a novel rug beating and cleaning action. The upper opposed side of the frame I prevents dust from rising directly above the rug or carpet cleaner and the entire cleaner is manually maneuvered over a rug or the like by means of the handle I0 and rollers I5 and I4 and caster I6. Vertical adjustment of the beater rings I3 relatively to the upper surf-ace of the rug A is accomplished by vertical adjustment of the screw IT in the boss lb of the frame I which causes deflection of the caster base I8 and consequent vertical movement of the axis of the shaft 20. The plate 22 forms a connector for the shafts 8, 9 and Ill preventing centrifugal force from separating the same at their middle portions.

Though I have shown and described a particular construction, combination and arrangement of parts and portions, I do not wish to be limited to this particular construction, combination and arrangement but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 2' 1. In a portable rug or carpet beating machine of the class described, the combination of a plurality of spaced substantially parallel shafts, means mounting said shafts for rotation about an axis centrally of said a plurality of shafts and a plurality of flexible resilient rings of a readily yieldable material on said shafts having openings therein equal to several diameters of said shafts, said flexible rings being yieldable in directions radially of each of said rings.
