JoIrNo. M RRA or WENATCHEE, wnsnmeron.
citizen of the United States, residing at Wenatehee, in the :county' of'chelanfand "State of Washington; have invented certain new and useful Improvements in Shoe-Polishing'Devices, o fwhic'h "the following is a specification, reference beinghad to, the accompanying drawings devices and has for its object to provide a device of this character" wherein a number of shoe polishing implements may be attached to a single operating means.
Another object of the ,lnvention'is to provide a device of this character including a motor and a flexible shaft, and polishing means carried by the end of the shaft.
Another object of the invention is to provide a device of this character wherein the end of the flexible shaft is provided with a 'novel'mandrel and coupling means whereby plement to hold the implement in engage ment with the coupling means regardless of the speed of the flexible shaft.
With the above and other objects in view,
the invention consists in the improved constructlon and arrangement of parts to be hereinafter more particularly described, I fully claimed and illustrated in the accompanyingdrawings, in which Figure 1 is aside elevation ofa shoepolishing device constructed in accordance with an embodiment of the invention,
Fig. 2' is a perspective view of the drel,
3 is a side elevation of the mandrel showing the catches, v
Fig. 4 is. a-perspe ctive view of the inner hub or liner of the polishing implement, and
Fig. 5 is an end view ofrthe polishing im-' plement applied to the mandrel.
Referring. to thedrawing's, 5 designates a conventional form of electric motor of compact design, the casing of the motor including a hook 6 by means .of which the motor may be; suspended from the rung of a chair or any suitable support. Connected to the all positions. 7 is provided ceive a mandrel 10. The of a tubular body member 11 having an end 3 siren-POLI HING, DEVICE.

long so as to'permit the deviceto be used in The end portion of the shaft with a rigid shaft 8 on which Specification of Letters Patent. P t te o t 25, 1; Aiaplicationfiled December 29, 1920. Seria1No.433,851 I a handle 9 is loosely mounted By this means the operator may grasp' the handle without'lnterfering with the rotation of the shafts 7 and '8, as the shaft 8 rotates within the handle. This invention relates to shoe polishing The end of the sh'aft8 projects beyond the end, of the handle and is adapted to 'remandrel consists wall 12, the outer edge of said wall projectmg beyond the side wall of the body member to provide an annular stop 13. Projecting from the intermediate portion of the end wall 12 is a socket member 14 adapted to receive the end of the shaft 8, a set screw 15 being provided to secure the socket member to the shaft 8.
A pair of resilient arms 16 are struck from the side wall of the body member, said arms being disposed remote from the end wall 12 and in diametricallyspaced relation to each other. The end of each arm is extended at right'angles to provide a catch 17 which pro- .jects exteriorly of the wall of the body memher. These arms are arranged so that the resiliencythereof constantly urges the arms outwardly of the wall of the body member. The arms may be readily operated by the fingers of the operator as the arms are free to move toward or away from each other.
The mandrel is intended to support a variety of polishing implements such as brushes of fine and coarse hair,'polishing cloth, wool, etc. Each ofthese implements consists of a hub 18 preferably of wood adapted to support the polishing implements. This hub is provided with an inner hub or lining 19 preferably of steel or like metal The lin ing or hub 19 is provided with a pair of op- I -member 11 of the mandrel so as to position the recesses 20 adjacent the catches 17. When the polishing implement is applied, the catches arefdepressed so as to permit the hub 19 to be moved toward the end wall 12. lVhen the polishing implement comes in contact with the stop 13, the catches then spring into the recesses 20 and firmly hold the implement on the mandrel, regardless of the speed of rotation of the shaft. The operator may then use the polishing implement in any position. Each implement is applied in the manner above described, the application and the removal being performed rapidly in view of the novel form of catches.
The construction of this device doe not limit its use to polishing shoes as the device may be used for all-- cleaning purposesland Where a rotating brush or member is desired.
it being possible to convey the motor 5 from placeto place as a relatively long connecting cord may be provided for connecting the motor to the ource of current. In addition to this the flexible shaft permits the polishing implement to be used in any position desired Without decreasing the speed of ro-g tation of the flexible shaft. I
What is claimed is za V A device of the character described c0m-.
prising a shaft, means for rotating said shaft, a mandrel, a socket member carried by the mandrel adapted to receive the end of the shaft, a top carried by the mandrel adjacent the socket and projecting beyond the exterior surface of the mandrel, said mandrel having resilient arms strucktherefrom, the ends of said arms being extended at right'angles to form catches exteriorly of the mandrel, a cleaning and polishing implement including a hub, said hub having opposed recesses in-one end thereof, and adapted to engage the mandrel, the catchesof the mandrel being adapted to extend into the recesses when the opposite end of the hub is .moved intoengagement Withthe stop of the mandrel.
