Application filed March 31, 1924. Serial No. 703,270.

To all fwhom 'it may concern Be it known that I, HEZEKLAH FoWnLL,.a citizen of the United States, residing at Kansas City, in the county of Jackson and lState of Missouri, have invented certain new and useful Improvements in Electric Shoe.

Cleaning and 'Polishing Machines, of the following is a'speciication.

My invention relates to electric shoe cleaning and polishing machines and one object 1s to provide a relatively simple, inexpensive and efficient machine of this character which whereby shoes and boots may be cleaned and polished at a much less expenditure of time and labor than when such work is performed entirely by hand.

'A further object is to arrange the parts in such manner that different kinds of brushes or other cleaning and polishing devices may be readily interchanged to suit the character of the Work to be performed,V

whether: the same 'be cleaning or polishing.

Another object? is to provide means for conserving electric current by automatically closing a circuit leading to the motor of the v cleaning and. polishing machine when the same is applied to,a boot or shoe, and means forHautomatically,interrupting said current the instant the cleaningcr polishing' element is lifted from the boot or shoe. Other objects will hereinafter appear and y -in orBer that the invention may b e fully unders accompanying drawing, in which:

Fig. l is an elevation, partly in section, of the cleaning andpolishing'machine. i

Fig. 2 is an enlarged cross section on line II--II of Fig. 1.

In carrying out the invention, I employ a motor 2, the housing 4 of which .is preferably of such length andl diameter as to form a convenient` handle for the operator.

6 designates a rimary tubular shaft extending axially `t rough the housing 4 and jca'rrying the armature Sof the motor 2.

10 designates a secondary shaft extending axially through the primary shaft 6 and having a pin-and-slot connection 12therewith,so that it may move longitudinally within said primary shaft 6 and at the same time be driven thereby. y

14 designates itself-opening switch which is arranged in a tubular extension 16 at one end of the motorhousing 4.A Said switch 14 comprises a pair of insulated movable conod, reference will now behad to the going arrangement tact members`18, and a pair lof insulated stationary contacts 20. The movable contacts 18'carry the motor terminals 22 and are normally'held out of engagement with the contacts 20 by aninterveninof spring 24, which also, through the intermedlacy of the insulation 26 between the contact members 18 pushes the secondar shaft 10 to the right, Fig. 1, until stoppe by its shoulder 28 contacting the ad3acent end of the primary shaft 6.

A cap 29 is screwed u pn the end of the extension 416 to exclu e" `dust from lthe switch 24.

An extension cord 30 provided with a plug 32 and connected to the contact members 20 is provided to enable the motor 2 to be readily connected to an ordinary lamp socket or other source, or supply, of electrical energy. f

34 designates a cleaning or polishing element mounted upon that end of the secondary shaft 10 remotefrom the switch 14. Said cleaning or polishing element 34 has a slotted socket 36 for enga ement over a stud 38 fixed to the secondary s aft 10. The -forepermitsy different kinds of cleaning or polishing elements to be readily connectedto the secondary shaft 10.

The operation briefly stated is as follows: When the cleaning or polishing element 34 is pressed against a shoe or boot by pushing forwardly upon the motor 2, such.pressure overcomes the resistance of the spring 24 and-forces the contact members 18 and '20 into engagement with eachother, thereby closing the motor circuit, whereupon the motor drives the cleaning and polishing element 34. through the intermediacy of the shafts 6 and 10. T he motor circuit remains closed so long as the cleaning and polishing element 34 is pressed against the shoe or boot which it is cleaning or polishing, but the instant it is removed from said shoe or boot the motor circuit is interrupted by the spring 24 opening the switch 14.

From the foregoing description it will be understood that I have provided a combination of coacting elements whereby the current is automatically cut of from the motor, except at such times when the cleaningand polishing element 24 is in actual operation, and While I have shown and described the preferred form of the invention, I reserve the right to make such changes in the construction, vvcombirriitionV and arrangement ofifi'xts`-as'-properly fall within the spirit an scope of the invention as claimed.

- Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

In a machine `of the characteru described the combination of an electric motor, a primary tubular shaft mounted in said motor, a, secondary'shaft rotatable with but slidable .longitudinally within said primary shaft,

anda sv'vitch-'asso'ciated with said motor to control the current thereto and-Which is antomatically closed by longitudinal movement 1n one direction'of sadsecondary shaft. In testimony whereofI aixmy signature 1n the presence of two Witnesses.
