i ,oeaoor To f// fur/wm i# may Concern:

15e it. known that Lloniurrl. Mt' CLHANY, a resident of Pittsburgh, in the county ot ,"tllegfheny'and State of Pennsylvania, have invented a ne and useful lnnorovement in tihoehininp; Machines. of ivhivh the tollowine is a specification.

My invention relates4 to machines for automatically polishing boots and shoes and it hasl `for its object to provide a maehineotthis character ivhir-h lhall be particularl)v strong` and durable in structure and reliable and ell'eetive in operation, and in which the power `tor driviugthepolishingbrushes shall he simply and eflqectively applied by auch meansI as shall be fre/e trom liability to displacement or breakage.

The frame work l for inclosing the mechanism embodying my invention is of skeleton torni and is surrounded and inclosed by a .suitable casing 2, only a portion of which 1s .shown infFig. l, such portion beingprovided with an opening 3 for the insertion of a shoe lto be polished. The front of the casing` is also provided with rods 5 to be grasped by the individual who is making use of the machine.

,eet or near the top of the frame work is av platform S upon which is mounted an electric motor 7, and, mounted in suitable bearings at the rear of the frame is vertical ghaft 8, the upper and of which 'is geared Patented June 11G, 1.9i 3.

to the electric motor by means of beveled gearing' 9, as indicated. The shat'tv 8 com prises three sections which are connected together by suitable couplings 10, and the middle section is provided with a worin 11 which meshes vvith a ivorm wheel 12 to drive shaft 14. Shaft 111 carries a rear l5 that meshes xvith a gear ivheel 1G mounted upon a shaftV 17, bearings for which are provided in the bracket 13. r1 `he shatt 1T is provided with crank arms 18, the free ends ot which are joined to the upper ends ot rods 19, The lower ends ot the rods 19 are connected to the outer ends of the shorter arms ot bell crank levers QU. rl`he bell crankr levers are mounted upon a shaft 21 having bearings in brackets 22 which are fastened to the trame. The free ends of the longer arms of the levers Q0 are connected by means of rods 2?) to al shaft 24C that is provided with guide wheels Q5 for a carriage 2G. Other supporting' and guide wheels 2T for the Par" ringe are also provided, which, together with wheels 25, rest and move upon guide rails 2S, connected at their ends with forward and rear supports 8G, .87, on a suitable base or frame.

Journaled in suitable bearings upon the base of the frame 1, beneath the carriage,' shaft 29 that is either square in cross sec-tion or is otherwise so formed as to receive a bevel gear Wheel S0 and rotate the same as the shaft is rotated and also permit longitudinal movement thereof. The ,shaft 29 is rotated by means ot a bevel gear 31 which meshes with a .corresponding gear wheel 32 on the lower end of the shaft 8 which is geared to the electric motor 7.

lviounted near the rear end of the carriage Q6 is a vertical shaft 33, preferably square in cross section, having!` thereon a toe brush 34 and a polishing brush 34 for the toe and top portion of a boot or shoe and having also a driving pulley 35, the polishing brush 34 having such connection to the shaft as to permit it to be moved vertically, independently et any movement of the shaft. but being rotatable with the shatt, in a manner well known. The toe brush 34 is.' intended mainly for preliminary cleaning of the toe of the shoe and tor the application of blacking thereto and is constructed wholly of bristles. The polishing brush 31 tilt-es Saum the cam to operate the brush-aetnlerer 65.

The shoe rest 59 is provided on its upper surface with a conparatircly large nuniher o sharnly pointed upwardly projeeting pegs which hy engagement with the sole ot the shoe tend to resist. the side thi-ust ot the polishing hrush 34 during operation. At its forward portion, the shoe rest 59, sh'oivn in Fig. 7, is further provided with a toe hook 73 whieh normally projeots upwardly in front. ol the. shoe and forms a stop for properly positioning the .saine prior to polishing thereof. The. toe hook 7i]- is pivoted upon the shoe rest 59 and is provided with a downwardly extending; lever 74 which projects into the path of a lug 75 upon a bar 7G fastened to a permanent part. of the hrush carriage. lllpon rearward motion of the carriage this lug To oontarts with the lever 7.4 and raises the toe hook into position. At the beginning of the fori'ard motion of the Carriage` however, the lug 75 moves out. of Contact with the leter 74 and the toe hook drops or" its own weight, thus giving room for the. operation oi` the brushes and full contarle thereoi with the shoe.

Vlihile the apparatus for supplyingr polishing material to either -the hrushesl or shoes to he polished may he of any desired kind, so ar as structural features are eoneerned, l Willhriefly desorihe the elements which l have embodied in my apparatus for supplying suoh material. ,provide an air-storage tank 68 in the upper part of the easingy and, adjaeent thereto, l mount. an air pump (Si). the piston rofl Z0 oi'f which is suitahly connected to the worm Wheel l2 in order that air may he compressed and supplied to the tank for use, desired. t a lower point, in the frame Work l support a tank '7l oi: polishing liquid and Connect` the air and liquid tanks hy n'ieans ot suitable. pipes to spraying nozzles 72 that are. properly loeated in order that the liquid may he sprayed upon the hrushes for application to the hoot or shoe to he polished. Uf course the spraying nozzles may he so located as tio spray the liquid upon the shoes direct, if so desired.

4The manipulation of suitable Valyesor eontr'olling the supply of air and liquid to the spraying nozzles may he effected hy means of' any suitable devices suoli as are well known in the art and are adapted for operation by the notor -and the gearing. lt will bealso understood that any Well known means. may be employed for automatically interrupting the circuit of the electric motor and that any suitable prepayment devices may be used in connection with. the spraying mechanism 'hy of properwhich the insertion of coin-oi tlf size and weight 'ani en se re e nome portion of the nieehanisin that. the manipulation of a lever or hutton will .serve to start'. the niaeliine in operation. lt is not heliet'ed to he neressary to deserihe in detail these features ot eonstruetion i'or automatieally .stoppingr the inoi'eineut and t'or starting' it hy ineans ot' a ruin and suhseiuieut manipulation hy pressure of an external push hui'- ton or leier. sinee such derives are well known in the art and in lgeneral use.
