Application tiled March 14, 1912. Serial No. 683,685.

To (IN whom if muy4 concern Be it known that I, llnxs'r lV. JonNsoN, a citizen of the United States, and residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Shoe- Polishing Machines. of which the following .is a specification. such as will enable those skilled iu the art to which it appertains to make and use the same.

l This invention relates to machines for polishing shoes. and the object thereof is to provide an improved machine of this class which is automatic in operation and which set for operation bv the, insertion of a coin and which is set in operation bv placing the foot on a'suitable support and forcing said support downwardly, which operation sprays thcshoe with liquid blackingand then puts in motion the polishing brushes with which the machine is provided. and the construction and operation heilig such that when the brushes, having completed their work ot' polishing the shoe the operation of the machine is .tut.omatici"y stopped, b v breaking the circuit of an electric motor b v which the machine is operated. and at which time the foot is removed vfrom the support and the operative parts returned to their normal position and autonmtiaillv locked.

The invention is fully disclosed in the tollowing spcciiication of which the accompanying drawings form a part, in which thc separate parts of my invention are :designated `b v suitable reference. 'characters in each ot' the views, and in which the bottom part of the Figure l. is a longitudinal vertical section ot my machine on the line 1-1 of F ig. 2`; Fig. Q a transverse vertical Sectio-11 on the line 2-2 of Fig. 3; Fig.` 3 a plan view of machine with the casing removed and parts broken away; Fig. .1. a side view of the machine on a reduced scale and with parts of the construction broken away; F ig. 5 a central vertical section through the top part of the machine and showingr the parts in inoperative position; and Fig. G a View similar to Fig. 5 but. showing the parts in an operative position.

l, designates a casing which houses the entire mechanism and is coinposed of a ver tic-.d top partI Q, and a horizontalbase 3. The top part 2 comprises a front wall 4,

and a removable `back 5, and is closed at the top and sides. as shown.

'lfhc front wall t is provided with an opening (5, which enters into a coin receptacle 7,and is closed by a door 8, having a suit able lock Sl. and above the opening l pro vide a coin support t0. which 't'orlns one side ot a slot l1, and passing throltgh th'e front wall l ot the top 2 of the casing l, and slidablv mounted in the slot ll is a plinger bar lit, having a thumb piece lil, at its outer end and provided with a circular coin aperture l-t, about cent 'al ot' its length which is adapted to receive a coin l5, when the machine is to be operated, as will hereinafter appear. The plunger bar' i2. `s further provided. near its inner end with spaced perforated lugs lt'. between which is pivoted a link 1T which is pivotallv connected at its rear end with a switch arm 1S. of a bell crank lever 19. mounted as shown at '20, in the ltop of the casing l, and having a short arm 2l. to which is connected a wire or cable 22. as shown.

ln order to prevent unscrupulous persons` vfrom operating the machine without dcpositing the necessary coin in the aperture 14. lV provide a stop dog Q25, pivotcd at Qt, immediately above thc plunger bar 1Q, and which is provided with a forwardly and do\\'i1\vardl v directed nose 25. which is tensionallv held in contact with thc plunger bar 12. and will enter the coin aperture 1.4. as it passes underneath, it there is no coin therein. and stop the inward movement of the plunger bar 1L. lt. however. the necesl sary coin is deposited in the aperture 14. the nose of/ thc dog 28, will ride over it. as the plunger bar 1Q. is ot the same thickness as the coin, as shown in Fig. 5, and the dog 223, is provided with a tail piece 2(3, connected with one cud ot a pull spring 2T. thc other end being anchored to the casing at 28.

livoted at QS). in the casing is a trip lever 30. having a downwardly directed arm 3l, ranging across thc path of niovement of the plunger bar l2. and a backwardly directed arm .32. havingl a trip wire or cable 33, c0n ncctcd therewith, and which is'adaptcd to rest on a stop pin 34, when the mechanism is in itsl inoperative position and locked as will be hereinafter explained.

The trip lever 30. is so placed that,` it

Civ

there is no coin placed in the aperture 14,

and the plunger bar 12, is forced inwardly, the nose 25 of the dog 23, will stop the inward movement of said plunger bar 12 before the rear end thereof contacts with the downwardly directed arm 31.

The switch arm 18 of the bell crank lever 19 is adapted, when the parts are in the operative position as shown in Fig. to make electrical connection between two contacts 35, which forni the terminals of a motor circuit 36. i

Secured to the back 5, of the casing is a bracket .37, having a grooved wheel 38, mounted therein andaround and over which is passed a chain 39, one end of which is provided with a weight 40, the other end being carried down to and around a grooved wheel 41, mounted at 42, and then forwardly to and around another grooved w-lieel 43,

; mounted at 44, to a stationary table 45, and

then downwardly to an eye or staple 46, fixed on a vertically movable bar 47.

The stationary table 45, is lsupported within the base 3, of the casing l, by standards 48, which are bolted to the table 45, and to the bottom 49 of the base 3, as .shown and these standards 48, are provided with integral keepers 50, in which are movable lock bolts 51, having reduced extensions 52,

assinr throii h can ieces 53 between which and the bolts 51,' are placed push springs 54, which normally tend to force the bolts, 51, against bars 55, vertically movable in central bo-res 5G, in the standards 48, and these bars 55, are connected at the upper ends thereof with a foot rest 57, which when the parts are' in the normal inoperative position assumes the elevated position shown in dotted lines in Fig. 1, and when in this position the bars 55, and foot rest 57 are held against downward movement by the lock bolts 51, project-ing into the bores 56, and underthe lower ends ofthe hars 55, as will be readily understood.

Connected with the reduced extensions 52 of the bolts 5l are wires or cables 58, which are passed around grooved wheelsf), :arried in a bracket 60, secured to the stationary table 45, and these wires or cables58, are

Vbrought together at 61, and connected to the trip wire or cable 33 which is passed around a grooved wheel 62, mounted in the base 63, of the casing, as shown.

The standards 48 are further provided with longitudinal slots 63, through which project perforated pins 64, to which are connected wires or cables 65 and (S6. which are passed under and around groovcd wheels (37 and 68, and the Wire or cable 65 is connected to the downwardly directed arm (if), of a bell crank lever 70, which is pivotcd at 71, in the base 3 of the casing.

The shorter arm 72, of the crank lever 70, has connected thereto a Wire or cable 78 which passes over and around a grooved wheel 74 rotatably mounted inthe base 3 and then backwardly and is connected to a grooved ,wheel 75, around which passes a wireor cable 76,*both ends of which are connectedas at 77, to a brush strap 78, provided with long bristles 79, as shown.

The wire or cable 66, at the opposite end of the footrest from the wire/or cable G5, is passed upwardly and around a grooved wheel 80, rotatably mounted in the base 3, and then backwardly and is connected to the lower end 81, of a lever arm 82, loosely mounted at 83, in a bracket 84, secured to the back 5, of the base 3' of the vcasing 1.

The lever arm 82, is extended abo-ve the bracket 84, and is connected at 85, With a wire or cable 8.6, to which is secured a grooved wheel 87, around which is passed a wire or cable 88, both ends of which are secured as at 89, to a brush strap 90, having` long bristles 91, as shown, and the brush straps 7 8 and 90 are U-.shaped in form and arc positioned so that the open sidesk are adjacent and this construction forms` an elliptical band brush whichl surrounds the shoe when in operation, and when given av quick circular reciprocatory, movement, thoroughly brushes the shoe as will be readily understood.

The vadjacent ends of the U-shaped brush straps 78 and 90 are provided with perforated angle plates 92, between which are placed cross-heads 93, having longitudinal reduced extensions 94, passing loosely through the angle. plates 92', and provided with nuts 95, between which and the angle plates 92, are placed spiral springs 96, which are carried on the extensions 94, asshown, and the cross-heads 93 are connected by integral right angle extensions 97, to blocks 98, slidably mounted on horizontal bars 99, mounted in fixed `standards 100, secured to the table 45.-

The slidahle blocks 98, have short pins 101, on which ai'epivotally mounted one end of pitman rods 102 and 103 the opposite ends of said pitman rods being carried on wristA pins 104 and 105 which are carried respectively oii a gear wheel 106, and a balance wheel 107, fixed to the opposite ends of a rotatable shaft 108, mounted in suitable standard bearings 109 and 110, and the wristA pins 104 and 105 are arranged opposite of cach other as indicated on dotted lines in (Fig. 1, so that when one of the sliding blocks reaches its outward limit of movement the opposite block has just reached its inward limitof movement, and this construction gives the band brush at opposite sides an op 4posite reciprocatory movement Asimilar to that used by boot blacks in polishing shoes. Y

'lhe standard bearing 110, is provided with a supplemental bearing 1.11, extending upwardly and'slightly backwardly and car- 120,in the Supplemental bearing 111.

ltrip pin 115, carried by the gear wheel 1013,

and a cam disk 116, is also fixed to the shaft 112, and is provided with a cam face 117, adapted to co-act with a beveled nose 11S, of u lever arm 119, pivotally mountednat Y forward end of the lever arm 119, is connected to the lower end of the wire or cable 22', and, when the parte are in the operative position shown in Figs. 1 and G, and after "the shaft 108, has made a predetermined number of revolutions,determined by the number of pins in the disk 113, in this case it"being ten, the came yface 117, will operate the lever arm 119, to exert a pull on the wire or cable 22, which Will throw the switch arm 18, away from the contacts 35, and

vbreak the motor circuit-to stop the mechanism.

The motor circuit 3G, coniprlses, in addl- `tion to the contacts and switch arm 18, a

battery 121, and a mechanically operated blade switch 122, secured in the base of the casing, which comprises .l standard 121-1. an insulating block 121, having` springl blades 125 and 120, secured thereto, one o i which, the blade 125, being backed up by a set screw 127, the blade 126 being in the path of a spring pressed plunger 128, having an enlarged head 129, movable in1a suitable keeper, as at 130, and one edd of which is provided witha beveled face 131, against which the lower end 'of` thevertically mov-, able bar 55, impinges to force the head 129, and a plunger 128 backwardly against the `spring blade 126, to' cause it to contact with the blade 125 to close the motor circuit.

The motor terminals are shown at 1212 and 133, and a conductor 131 is connected to the terminal 133, and with 4the switch blade 1213, another conductor 1,35, is connected to the switch blade 125, and through the battery to one of the contacts 2.15, and another conductor 13G, is connected to the other of the contacts and with the motor terminal 132.

In order to give a high polish to the top of `the toe part of the shoe, I provide a swinging brush 137, which operates in a horizontal plane over the front of'the shoe and swings upwardly and baclnvardly,l out of sight, when not in use.` Mounted on the extreme rear end of the table 415, is a stand-- ard 138,11aving a socket 139 in its top to receii'e a pivot pin 14:0, which is provided with f, an annular groove 141, adapted to receive seI the end of a retaining screw 112. The pivot pin is carried by a forked block 113, through which is passed a shaft 141,`on\\vliich is mounted, in the forked block `143, the re'- duced shank 145, of the brush 137, which is provided with a tail piece 146, to limit its upward and backward movement, as will be readily understood.

The lever arm S2, is provided with an angular extension 147, and connected therewith is a wire or cable 148, passing over and around a grooved wheel 149, mounted in the base` 1-1 o1' the casing; and is then connected with the shank 145, ot' the brush 137 at 150.

'lhe motor is shown at 151, the motor shal't at 152, and the power gear a't 153, which is meshed with the gear 1011, and drives the machine when in operation.

l`he foregoing all pertains to the control and operation of the polishing mechanism and .l will now describe the automatic pneumatic means for spraying the shoe with liquid blacking' as it enters the base J1 of the casing and before tht polishing means is set in operation.

The base 3 o1 the casing is provided with an opening 154, through which the foot rest 5T, normally protrudes slightly, it being nornmlly held elevated as lndicated by the dotted lines in Fig. 1 and full lines in Fig. 1, by the weight 40, as will be readily understood.

When it is desired to get a shine. a coin in Figs'. and causes a pull to be exerted on` the wiresl or cables 22 and 38, and this closes the motor circuit through the switch arm 18.`

rI`he pull on the wire or cable. 22, throws the beveled nose 11S, down in the path of the cam face 11T, while the pull on the wire or cable 321, withdraws the lock-bolts 51, from under the lower ends of the bars o5. The toot is now placed on the foot rest, 57, and sutlicient pressure is placed on the foot to depress the foot. rest against the action oi tbe weight #1-0. As thefoot rest descends; air is 'forced through flexible tubesv155, through tbc instrumentality ot' piston rods 1515, pistons 157, and cylinders 15b;` the pist'onrods 1511', being secured to the descending foot rest 57. while the cylinders 15S, are secured to the table Lt5. The cylinders are provided just below the upward limit of movement of the pistons 157, with air inlets 159, which are closed just as soon as thc',

pistons start downward.

The cylinders are provided nearthe lower ends thereof with air outlets 100, and the tubes 155 are connected with these outlets as at 1111 and said tubes 155, are. connected at or near the top ot' the base 3 of the casing, with horizontally movable metallic pipes 11.12, passing through suitable keepers 11121, and connected with blacking spray-pipes 1131. ot' semi-elliptic form and provided with small perforations '1135, in the inner walls thereof and these perforations are carried around the rear end of the sprays So that the front as well as the sides ofthe shoe wardly over and around grooved wheels 177,

liengitanks 169, to the spray-pipes 164.

In order to separate the spraypipes'164, after the shoe is polished to permit the foot to be withdrawn, I provide slidable bars 170,

mounted in keepers 171, and having reduced 'slidable extensions 172, slidable in keepers 173v Abetweenwhich and the bars'170, are placed springs 174, as shown, and stop pins 175, are provided to limit the inward inovenient of lthe spray-pipes 164,

It will be understood that all of the keepers 163-171, and 173 are secured to the underside of the top of the base 3701i the casing.

Secured to-tlie reduced extensions 172, are wires or cables 176, which are carried outand then downwardly7 and connected with outwardly directed arms 178,y of bell crank levers i179, pivoted at 180, in brackets 181,

'secured to the side walls of the base 3 of the casing. and wires or cables 182 are secured at 183, to the vertically movable bar 47, and are passed under and around grooved wheels 184, and then ,outwardly and secured to downwardly .directed arms 185 of the bell crank 1ever17 9, as shown.

.In order to impart to the brush 137 a horizontal si'inging reeiproeatory movement over the toe portion of the shoe, 'I provide thev shaft 144 with slot-ted extensions 186, which are adapted to receive pills 187 car ried by horizontally movable forked bars 188. slidable in suitable keepers 189, secured to the t-wo rear fixed standards 100, and the rear ends. of the block 98 are provided with lateral shoulders 190, which are adapted to strike the front ends of the opposite bars 188 alternately to oscillate the'bar 144, on` its pivot pin lil-0, and give the brush a swinging:r reciprocatory inoveineit as hereinbefore stated.

lVhen the machine is at rest or when the parts are in the inoperative position, the lock bolts 51, range across the bores 56, and underlies the lower ends of the bars 55, and lock the foot rest 57, against downward movement, but when a coin is inserted in the recess 14, and the plunger bar 12, pushed inwardly it strikes the arm 31, ofthe lever 30', and rocks the saine which creates an upward pull on the' trip wire or cable 33 and this operation withdraws 'the lock bolts 51, from the bores 56. after which the foot may be `placed on the foot rest 157, and pressed downwardly, and'as the foot rest and its associated parts descend, the wires or cables (i5, 66 and l82`are drawn outward over the ,g'i'ooved wheels 67, 68 and 184 by the action of the springs' 94 and 174, which operation forces the brush straps 78 and `90 and .the spray-pipes 164, inwardly in close relation to the shoe to be polished. The` downward movement of the foot rest 57,'also acts to 'release the pull on the wire or cable 148, and

*this permits the brush 137, to drop down' over the toe of the shoe and just b re the` foot rest reaches its downward limit of movement and after the shoe has been sprayed with liquid blacking, thelower end of the rear bar 55, strikes` the cam face 131,. of thepliinger 128,. and forces said'plunger backwardly to close"the switch 122, kand I starts the motor which operates the brushes to. polish the shoe.. and as hereinbcfore in ovements of the polishing brushes, the motor circuit is automatically broken by the cani face 117, operating the 1ever`119 to exert a downward pull on the wire or cable 22 which throwsl the switch arm 18,: out of, en.-

gageinent with the contacts 35 asy will be readily understood. It will also 4be under# stood that the weight 40, acts to elevate the4 foot rest 57, which operation separates tlie` -stated after a predetermined v.number of so brush straps 78 and 90, as indicated by dot tedlines iii Fig. f5, and also separates the spray-pipes 164. after themacliine coines to a stop and asthe foot is being withdrawn from the machine.

.l do not desire to be understood as limiting myself to the detail features' and construction and arrangement of parts as herein shown and (lesci'ihed, as it is manifest' that` variations and modifications therein inay be resorted to, in the adaptionof in v, invention to varyingyconditions of use without departing from the spirit and scope of niy invention and improvements. 'I there.- fore reserve the right to all such variations and inodications iis'properly fall within the scope of inv invention and the ternis ofthe following,T claims.

Having fully described in v invention what l claini as new and desire to secure by Letters Patent is 1. ln a shoe polishing machine, the combi* nation with a band brush 'adapted to eiicircle a shoe and consisting of two sections resilientlv conneeted'and held. together, lot' an adjustable foot-rest and ineans 'for separating' the sections ofthe band brush upon the elevation of the foot-rest.
