Fig. 9-is an elevation of the gearing andthe switch operated byit; and Fig. 10 1s a plan view of the same. Y

The object of my invention is to construct a shoe blacking and polishing machine which shall be set in Jmotion by the application and downwardpressure of the foot of the person wearlng the shoe, and one which will complete the cleaning and polishing operation in a short space of time.

Inv general the device consists of a suitable base over which is mounted a cam plate carrying suitable tracks conforming to the gen` eral contour of a shoe, the said tracks being i adapted' to properly direct the brushes vin their sweep about the shoe, and furthermore to glve, through the instrumentality of certain intermediate mechanism, the proper inclination to the brushes as they contact wit-h the shoe in their rotation about their own axes, thus causing the said brushes to make Contact with the entire surface intended to be polished. It consists too of mechanism which will impart a slow motion to the brushes in their revolution or sweep about the shoe, and acomparatively rapid motion about'their own axes.

The machine is composed of duplicate parts c so that both shoes Ican be operated upon siin suitable bearings 2 the driving pulleys 3 connected to any suitable source of` power. The driving shaft 4 of each pulley is suitably feathered and carries a sliding clutch mechauism 5 which when moved in a proper direction imparts motion to the gear wheel 59 (see Fig. 3) mounted on shaft 4which is journaled in bearing 60, and alsoto the bevel gear wheel 7 mounted on the same 'shaft 4. The two clutches are linked vtogether by a series of 1evers 8 and 9 pivoted respectively in bearings lOand 11 ou the bed plate 1. From the pivotal point of the levers8 and 9 there extends upwardly a rod 12 the lupper end of which carries a foot rest 13,.tl1e upper portion of saidV rod being suitably guided by'a collar 14 projecting from `suitable shaft bearings on topof the cam plate and to be hereinafter described.

The pressure ofthe foot on the rest 13 will depress the rod 12 and as the latter is depressed it will by virtue of the link connections just described cause the clutches 5 to be shifted in proper direction for imparting motion to thetgears 59 and the bevel gear 7. A gear wheel 6 also journaledin bearing 60 and meshing with gear 59, meshes with a gear 15..l

secured vto the end of a shaft 16 mounted in suitable bearings 17 at the bottom of a flat cam plate 18 (to be presently described)- IOO will be presently described. Thetubular eX- tension 22 extends above the upper surface of the cam plate 18, and to its upper projecting end are secured preferably three arms 24, collectively called'a carrier. This carrier is best shown in Fig. 2. At the meeting ends of each arm is secured a fixed bearing 25 in whichis mounted one end of a feathered shaft 26, the opposite end of which co-operates with a bevel gear 27mounted on the sliding bearlng 28 at the opposite end of said arm 24. The bottom of each sliding bearing 28 is provided with an anti-friction roller 29 which is adapted to move in the outer cam track 30 of the cam plate 18. The shape of the track 30 conforms to the general contour of the shoe, and as the arms 24 rotate, the sliding bearings 28 are carried around along the track 30, moving of course at the same time to and from the xed bearings25, within ysuitable guides 31 formed on each arm 24.

I have spoken of the shaft 26; I will now describe the mechanism for imparting motion thereto, and the manner in which said shaft imparts motion to the brushes about their axes as they are being carried around the shoe. The hollow shaft 23 above'referred to and which embraces the rod l2 carries at 'its lower end a bevel gear 32 (see Fig. 7) which meshes with the bevel gear 7. The motion imparted to the hollow shaft 23 is rapid as compared with that imparted to the carrier revolved by the worm gear 21. To the upper endof the hollow shaft 23' is secured a bevel gear 33 with which meshes the beveled pinion 34 of each feathered shaft 26 above referred to. The feathered shaft 26 operates the bevel gear 27 keyed thereto as bestshown in Fig. 5, and the gear 27 meshes with the bevele d gear wheel 35 mounted at the outer upper portion of the sliding bearing 28. The shaft 36 of the gear wheel 35 carries a fork 37 within which is mounted by means of a pin 38 a block 39 and to the block 39 are pivotally secured the embracing arms 40 by means of a pin 41. The arms 40 form the lower portion of the cylindrical stem 42 of the disk 43 over which the brush 44 is mounted and to which it is secured, As the arms 40 freely span the block 39 and the block itself is adapted to oscillate on the pin 38, it is apparent that this arrangement forms a knuckle joint at this point and thus allows the brush to be tilted to any desired inclination.

`Loosely embracing the cylindrical stem 42 is a collar 45 to which are pivotally secured the ends of the arms 46 between the outer ends of which is loosely secured the lever'47 having a pivotal bearing 48 on the upper sur- 'face of the sliding bearing 28. The lower end of the tilting lever 47 carries an anti-friction roller 49 adapted to run in the cam tracks 50 and 51 in a manner to be now described.

It is apparent from the above that as the carrier composed of the revolving arms 24 is revolved as already described, each arm will carry around in the path of the cam track 30, the sliding bearing 28, and as best seen from Fig. 4, the said bearing will carry the brush 44 with it, and while the brush is thus being carriedaround, it will at the same time be ro-` tated about its own axis by the bevel gear wheel 35 meshing with the bevel gear wheel 27 operated by the shaft 26. It is apparent too that as the brushes are thus carried around the shoe, they should successively receive different inclinations so as to come progressively in contact with the different portions of the surface of the shoe. In Fig. 4, while the lower end of `the tiltingv lever 47 is describing the path of the cam track 50 the brush secured to its opposite end will assume one inclination, and when the lower portion of the same lever describes the path indicated by the outercam track 51, thejbrush will asgressively in contact with different portions of the surface of the shoe treated (see dotted positions of the brushes in Fig. 3). It becomes necessary therefore to devise mechanism for shifting the lower Aend of the lever 47 from one cam track to the other and back again tothe irst so as to give different inclinations to the brushes i-n their revolution about the shoe. This mechanism is vas follows: Immediately above the worm gear wheel 21 (see Fig. 7) is secured to the tubular extension 22, a gear wheel 52 meshing with the large gears 53 on either side thereof, the said gears 53 depending from'the bottom vof the cam plate 18. On opposite faces of the gear 53 and v diametrically separated from each other, are secured segmentally curved guide strips 54. As the gear 53 is revolved (it being revolved by the sh aft 16 which drives the carrier above the cam plate) the guide strips 54 come successively in contact with the arms 55 and .5 6 of a switch 57 pivoted in abearing 58 on the cam plate and in such a position that the switch oecomesa part of one or the other cam track according tothe position occupied by said switch, very'much as aswitch on a railroad track. As the gear 53 revolves the strips 54 of course operate the switch 57 alternately in opposite directions, one strip 54 operating one arm 55 on one side, and the strip 54 on the opposite side restoring the switch by operating the arm 56 on the opposite side. Of course the switching voperation is not done suddenly, it not being completed until the strip 54 has completely passed the end of the arm 55 or 56, but the mechanism is so timed that after the'roller 49 has made a sweep of one track 50, it will be shifted on to' the track 51, from which it willbe shifted back again on to the track 50, and so on iudefinitely; so that this arrangernent'will give the brushes a varying inclination in their ro,-

tation, and during their revolution about the y doing this, which is to be made thev subject matter of a separate application.

The operation is obvious from the description. It is apparent from the arrangement of gearing best shown in Figs. 1 and 7, that the motion for carrying the brushes about the cam track andA thus about the shoe, is a slow one, this being necessarily so to give ample time for a polish; but the motion for rotating the brushes about their own axes is comparatively rapid so that a polished surface can be insured. The rapid motion is imparted through the medium of gear '7, gear 32, hollow shaft 23, gear 33, bevel pinion 34, shaft 26, gear 27, gear 35, shaft 36, and cylindrical stem 42 carrying the brush. It will therefore be seen that as the brushes are carried around the cam tracks at a slow-rate, and

` in conformity to the contour of the shoe, they are rotated rapidly about their own axes, and progressively tilted or inclined so as to sweep the entire surface of the shoe to be cleaned and polished.
