"This invention relates generally to shoe shining machines of the type wherein shoes are shined while remaining on the feet of a customer who stands in front of the machine. In'particular, the present invention is directed to the manner in which the rotary shoe shining brushes are mounted on, and secured in driven relation to, power actuated spindles.

The invention provides a novel arrangement for readily and effectively securing each rotary shoe shining brush on the corresponding, driven spindle; the brush as so secured being maintained in proper axial position on the-spindle, positively driven, and yet is quick-detachable for cleaning, repair, or replacement.

The invention further provides a mount, as above, wherein a brush can be secured to its spindle, or detached therefrom wholly by hand; no tools being required for the purpose.

The invention additionally provides a practical, convenient, and reliable driving mount for rotary shoe shining brushes, and one which will h be exceedingly eiiective for the purpose for which it is designed.

These objects are accomplished by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claim.

In the drawings:

Fig. 1 is a sectional elevation of a rotary shoe shining brush secured to a driven spindle of a shoe shining machine by means of the present invention.

Fig. 2 is a similar view, but shows the spring as compressed and the holding pin removed.

Fig. 3 is an outer end view of a rotary shoe shining brush mounted as in Fig. 1.

Referring now more particularly to the characters of reference on the drawings, the numeral I indicates a horizontal projecting spindle of a power actuated shoe shining machine.

The spindle I is supported, adjacent its rear end, by a fixed bearing member 2 which includes a bore 3 in which the spindle I is rotatably engaged.

The spindle I is prevented from axial displacement in the bore 3 by means of a collar flange the present instance the hub 5 is an integral part of a pulley 6 which pulley is driven by suitable means (not shown) to impart rotation to the spindle I.

A rotary shoe shining brush, indicated gener- 2 ally at I, is releasably mounted, in driven relation, on the forward end portion of the spindle I in the following manner:

The rotary brushl includes a hub 8 from which the brush bristles 9 radiate; said hub 8 having an axial bore I0 therethrough from end to end.

The diameter of the axial bore I0 is such that the forward end portion of the spindle I engages therein in relatively close matching relation.

The driving connection between the spindle I and hub 8 of the brush 1 comprises a cross pin II engaged in and projecting symmetrically at opposite ends beyond a cross bore I2 in the outer end of said spindle I. Escape of the cross pin I I from the cross bore I2 is normally prevented by reason of the fact that said pin is cradled in a transverse groove I3 in the adjacent end of the hub 8; such groove intersecting the bore I0 of the hub. The groove I3 is of only slightly greater length than the cross pin ll, so that as long as the pin is in the groove, said pin cannot escape the spindle.

The hub 8 is normally urged in a forward direction, whereby to maintain the cross pin II in the groove I3, by means of a relatively heavyduty, normally loaded compression spring I4 surrounding the spindle I between the collar flange 4 and the inner end of the hub 8. With this arrangement it will be recognized that while the spring I4 normally urges the hub 8 forwardly to maintain the cross pin I I in the groove I3, nevertheless the brush 1 can be manually removed from said spindle, without the use of tools, by merely shifting the hub 8 inwardly against the spring, to the position shown in Fig. 2, and thence pulling the cross pin II. Mounting of the brush on the spindle is likewise capable of being accomplished readily and manually by a reversal of the above procedure. A person can thus remove the brush 1 for cleaning, repair, or

replacement in a ready and convenient manner.

Also, the brush 1 can be reversed on the spindle I, as its opposite end is formed with a similar pin receiving transverse groove I5.

The outer end of the hub 8 is normally fitted with a snap-on or friction-held spinner or cap I6 which encloses said outer end of the hub, together with the adjacent cross pin and groove assembly, whereby to prevent shoe access to the outer end of the spindle I and the adjacent cross pin connection.

From the foregoing description it will be readily seen that there has been produced such a device as substantially fulfills the objects of the invention, as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claim.

Having thus described the invention, the following is claimed as new and useful, and upon which Letters Patent are desired:

A mount for removably and reversibly securing a rotary shoe shining brush in driving relation on a driven bearing-supported spindle having a free unsupported end portion projecting from the bearing, the brush including an elongated hub having an axial bore to slidably fit over said end portion of the spindle; said mount comprising. a loaded compression spring on the spindle between the bearing and the adjacent end of the hub and urging the latter toward said end of the spindle, and a removable cross pin in the spindle adjacent said end thereof; the hub being reversible on the spindle and having a diametral groove in each end to receive the cross pin, the groove being deeper than the diameter of the pin whereby the end of the spindle, when the pin is seated in the groove, may lie substantially flush with the adjacent end of the hub.
