Referring" to the drawings, the iinprbveu anto; matic shoe shining' unit shovvn therein c'r'n'- prises, in genera1'sets ofL polishing brushes housed within a casing and means accessible frorrl the" exterior of the Acasing fori presenting shoes to' the" brushesfor'cleaning andpolishin'g; motor-dri en" mechanismfor operating the brushes to' cause simultaneous rotation andVA oscillation thereof; nuid pressure: actuated means for delivering, fil. ish to' the' brushing zone; and coin-controlled means forselectiv'ely effectingac'tuation eitlhiefroil the biusli Operating' m'e'clansm only" OT" df'bb the brush operating mechanism and the polish delivery" means".

Each set of brushes preferably comprises a pair of side brushes II] having axially-extending bristles II and a toe brush I2 having radially extending bristles I3, the aXially-bristled brushes I being adapted to snugly engage the opposite sides of a shoe I4 with the radially-bristled brush I2 adapted to likewise snugly engage the toe portion of the shoe I4 when the shoe is placed on the support I5 and moved forwardly to the brushing zone on the guides I3 through the opening I8 in the casing I1. Each of the aXially-bristled brushes I0 is carried by a stub shaft IS journalled for rotation in the lower end of a supporting arm 20 hingedly connected at 2I adjacent the upper end thereof to one of the supporting elements 23 of a composite bracket 22 to permit lateral swinging movement of the brushes I0, each bracket 22 comprising integrally connected sup.-

porting members 23, 24. The brushes Il of each set are constantly urged toward each other and toward and against the shoe I4 by the action of helical tension springs 25, each of which is attached at one end to a lug 26 of its respective arm and at the opposite end to the cross brace 21 of the bracket 22. The radially-bristled brush I 2 of each set is mounted on a shaft 28 journalled for rotation in the ends of a pair of substantially horizontal supporting arms 29 pivotally carried at 3U by the lower ends of the supporting element 24 of the composite bracket 22 to permit vertical swinging movement of the brush I2, and the brush I2 of each set may preferably be constantly urged downwardly toward and against the toe of Vthe shoe I4 by the action of a helical compression spring 3| coacting with the support 24 and the brush supporting arm 23. lThe entirev brush assemblages hereinabove described, includn ing two sets or series of brushes for right and left shoes, are all swingably suspended from a common shaft 32 which carries each of the composite brackets 22, and the brushes are all adapted to be simultaneously oscillated relative to the shoes I4and their supporting members I5 in a manner to be hereinafter more fully described.

To drive the sets of brushes, a motor 35 and a series of motion transmitting chains and sprockets and belts and pulleys or sheaves are provided. The motor 35 directly drives a sprocket 36 which, in turn, is connected by a chain 31 to a sprocket 38V for transmitting rotary motion thereto. Keyed to the shaft 39 of the sprocket 38 for rotation therewith is a pulley or sheave 43 adapted to drive a belt 4I and transmit rotary motion therethrough to a pulley or sheave 42 keyed to the shaft 32. Also keyed to the shaft 32 for rotation with the pulley 42 is a series of pulleys or sheaves 43, 44, each of the pulleys 43 carrying a belt 45 adapted to transmit motion to a pulley or sheave 46 keyed to the shaft I9 of one of the brushes I0 for rotation of these brushes Ill and each of the pulleys 44 similarly carrying a belt 41 adapted to .transmit motion to a pulley or sheave 48 keyed to a shaft 49 which is journalled for rotation in a pair of the arms 26 adjacent the pivotal connection 30, each shaft 49 likewise hav ing keyed to it a sprocket 56 connected .by a chain 5I to a sprocket 52 keyed to the shaft 28 of each brush I2. Also. keyed to the shaft 35 for rotation with the sprocket 38 is a sprocket 53 in turn connected by a chain 54 to a sprocket 55 keyed to a shaft. 56. The shaft 53 also carries a, crank 51 forv each set of brushes, each crank 51 being connected by a rod or pitman 53 to one of the brackets 22.

It is apparent from the foregoing that vduring operation of the motor 35 rotary motion is transmitted to all of the brushes It through the sprocket 36, chain 31, sprocket 35, shaft 35, pulley 4I), belt 4I, pulley 42, shaft 32, pulleys 43, belts 45, pulleys 46 and shafts I9 and rotary motion is similarly transmitted, to each brush I2 through the sprocket 36, chain`31, sprocket 52, shaft 35, pulley 45, belt 4I, pulley 42, shaft 32, pulleys 44, belts 41, pulleys 48, shafts 49, sprockets 55, chains 5I, sprockets 52 and shaft 26. Simultaneously with the rotation of the brushes, oscillatory motion is transmitted thereto through the sprocket 36, chain 31, sprocket 38, shaft 35, sprocket 53, chain 54, sprocket 55, shaft 55, crank 5l' and connecting rod 58.

In addition to operating the brushes as here-y inabove described, the motor 35 drives a sheave 6I mounted on the motor shaft, motion from the sheave 6I being transmitted by a belt 52 to a sheave 53 mounted on the shaft of an air comu pressor 64 to drive the compressor. Air from the compressor 34 is forced through a pipe 65V to an air storage tank 63 and from the storage tank 66 through a pipe 61 leading directly to the top of a shoe polish storage receptacle or tank 38 provided with a relief valve 5S. A pipe 1li leads from the lower portion of the polish receptacle 63 below the normal level of the polish to a polish control and shut-off valve 'Il which is operable by a connection 12 to periodically deliver successive batches of polish into a pipe 13 leading from the valve 1I. The air supply pipe 61 also communicates, thro-ugh a pipe 14, with another valve 15 which is operable by another connection 13 to periodically deliver compressed air through a pipe 11. The lpipe 11 communicates with the upper end of a polish ejection pipe 18 past theY lower extremity of the pipe 13, and the lower portion of the pipe 15 is provided with outlet nozzles 19, which are directed respectively toward the brushes I2, I3. With this assemblage, Whenever air under pressure from the supply reservoir 55 is permitted to flow through Vthe pipe 61 and the valves l, 15 are open, a slug of polish will be delivered from the receptacle 58 and this slug will be transported by the air delivered past the valve 15 into the pipe 18, by ejector action, from whence it willbe sprayed upon the brushes through the nozzles 1S, 8i), branches of the pipe 18 leading to each series of brushes.

The control means for effecting actuation of the operating mechanism comprises, a i'lXed locally-interrupted annular contact plate 83 connected in the usual manner by wiring BI to one terminal of the motor 35 and a peripherallytoothed control wheel 84 keyed to a shaft 85 and suitably insulated from the plate 83 and connected to the other terminal of the motor 35 by wiring 32, the control wheel 84 having a laterally projecting pin 85 revolvable with the wheel in contact with the plate 83 to provide a closed circuit and eifect operation of the motor. Radiating from the shaft 35 carrying the wheel 84 is a pin 81, and when this pin 81 is in vertical upwardly extending position as shown in Fig. l, the contact pin 86 on the wheel 84 is adjacent the local interruption or gap in the plate 63 and out of Contact therewith and the motor 35 is thereby rendered inoperative.

To initially angularly displace the control wheel 84 so as to carry the pin 86 across the gap and into contact with the plate 33 to start the motor 35 and operate the brushes I6, I2, a ooin-receiving means is provided which comprises, a slotted cover 88 forming a guide for a longitudinally slidable starting arm 80 having a through opening therein which is alinable with the slot in the cover 88 to receive a coin of a particular denomination, the arm 89 having an upright gripping portion 9| at one end thereof and a downwardly inclined hingedly connected actuating portion S2 at the opposite end adapted to abut the pin 81 and initially angularly dis-i place the pin 86, shaft 85 and wheel 84 upon Virl-- sertion of the proper coin in the opening or slot 00 and subsequent forward movement of the arm 80 by means of the grip 0| in an obvious manner, the coin falling through the opening 90 into a coin receptacle 93 upon movement of the arm 8'9 a predetermined distance forward. As the pin 86 is initially carried across the gap and into contact with the plate 83 as described, the electrical circuit for the motor 35 is closed and the motor is thereby started, the brushes l0, I2 being caused to rotate and simultaneously oscillate as hereinabove described. A pawl 94 is pivotally carried by one of the elements 23 of the composite bracket 22, the free end of the pawl 95, coacting with the peripheral teeth of the control wheel 84 in a manner hereinafter more fully described. To maintain the pawl 90 in contact with the teeth 05, a coil tension spring 06 attached at one end to the medial portion of the pawl 94 and at the opposite end to a lug 01 on the element 2 0f the bracket 22 and a chain 0i! attached to a lug 99 on the pawl 91| and to the bracket 22 are provided. As the bracket 22 and the brushes carried thereby are oscillated by the driving means, including the crank 51 and pitman 5B, as hereinabove described, the pawl SM engages the teeth 95 of the control wheel 84 to rotate the wheel 84, shaft 05 and pin 81 counteru clockwise by increments in an obvious manner. As the wheel 84 approaches one complete revolution, `the inclined portion 92 of the sliding memher 89 is raised about its hinge |00 by the pin 81, falling to position adjacent the pin S1 as the wheel 34 reaches the position shown in Fig. l and cornes to rest with the pin B5 in the gap of theplate 03 and out of contact therewith, thereby L halting the motor and operation of the brushes l0, f2.

The coin-controlled means for effecting simultaneous actuation of the brush operating mechanism and the polish delivering means comprises, a similar slotted coin-receiving cover and guide i0! for a longitudinally slidable starting arm |02 having an opening therein for' receiving a coin of a different denomination, the arm |02 having an upright gripping portion substantially like the portion 0| of the arm 80 and additionally having a lug |03 formed for coaction with the shoulder 04 on the member 80 above the hinge |00 so as to slide the member or arm 80 and the actuating portion 92 thereof forwardly upon insertion 0f the proper coin and longitudinal forward movement ofthe arm |02, thereby initially angularly displacing the pin 81, shaft 85 and wheel 84 to carry the pin 80 across the gap and into contact with the plate 33 and consequently start ing the motor 35 and operation of the brushes as hereinabove described. The forward portion of the arm |02 is inclined downwardly at |05 and is adapted to coact with one arm of a `bell crank |06, as shown in Fig. upon forward movement thereof, the other arm of the bell crank |05 being cooperable `with the end of an axially movable `shaft |01 journalled in bearings E08 to shift the shaft |01 laterally toward the side of the sprocket wheel during such forward movement of the 6. arm |02. A crank |09 is formed at the end of the shaft |01 adjacent the vwheel 55 and a lug l0, cooperable with the crank |09, is `provided on the side of the wheel 55 so that when the wheel is driven by the motor and the shaft |01 is shifted as aforesaid with the crank |00 substantially against the side of the wheel 55, the lug l |0 will .contact the crank |09 and rock the shaft |01 clockwise. An arm is rigidly attached at one end thereof to the shaft |01 for rocking movement therewith, the swinging end of the arm carrying a rod H2 rigidly connected. to the arms 12', 15 respectively associated with actuating mechanism H5, H0 for operating the valves 1|, 15 respectively. From Fig. 4, it will be noted that the arm 12 merely engages a peripheral notch ||1 in the actuating member or plate ||'5 of the valve 1| which is constantly urged to clos ing position by a spring H8, whereas the rod 0r arm 15 is pivotally connected to the actuating lever H5 of the valve 15. Suchassemblage permits only momentary opening of the valve 1| by movementof the arm 12 to the right as viewed inthe drawings, the end ofthe arm 12 becoming disengaged from the notch |1 during such move ment andthe spring instantly returning the valve actuating plate ||5 to closed position. This momentary opening of the valve 1| however permits a slug `or batch of polish to pass to the pipe 13 from the receptacle 68 and this polish is then delivered, as hereinabove set forth, by ejector action of the compressed air passing through the open valve 15 and pipes 11, 18, the valve 15 remaining open until automatically closed as hereinafter set forth. Also radiating from and rigidly attached to the shaft |l01 is a trip lever l adapted to be rocked clockwise with the shaft |01 to engage a latch 20 simultaneously with the opening of the valves 1|, 15 as aforesaid, the latch |20 thus holding the lever H9, the shaft |01 and the arm in tripped and latched position. Another arm |21, radiating from and rigidly carried by the shaft |01, is attached at its free end to a coil tension spring |22 which constantly urges the shaft |01 and parts carried thereby counterclockwise and the latch 20 is similarly urged counterclockwise and against the trip lever l 9 bya coil tension spring l 23 coacting with an arm thereof, thereby assuring retention of the trip lever I l0 in tripped and latched position. The latch |20 is positioned adjacent the side of control wheel 84 which has a `laterally` extending lug |24; and as the wheel 84 is rotated by increments in a counterclockwise direction by the action of the pawl 04 with the peripheral teeth 95, the lug |20 is lmoved toward -ari arm of the pivotally mounted latch |210 causing release of the lever HS from the latch |20 `as the lug E20 contacts the latch arm. As the trip `lever iid is `disengaged from the latch |120, the spring |22 causes the shaft |01 and the elements `carried thereby, including the arm to rock counterclockwise back to the position shown in Fig. e, `thereby closing the air valve 15 through the connections ||2, 16, and H6. The lug |24 is preferably so located that the valve 15 is permitted to remain open for only a relatively short time, sufficient to deliver the polish in the pipe 13- to the brushing Zones through the pipe 18. To prevent backward rotation of the wheel 811 `during all of the operations hereinabove described, a pivotally mounted latch pawl |25 is provided, the latch i25 having one arm thereof `engaging the teeth and constantly urged into 7. engagement therewith by a coil tension spring |26 coacting with the other arm thereof.

While the operation of the improved unit is believed apparent from the foregoing detailed description, the operation may be briefly summai-ized as follows: The operator may rst preferably be seated on a seat provided on the support lli with his or her shoes IA; resting on the shoe supports l which are then slid through openings i8 forward on the guide rails i6 to a position between the brushes lli and with the toes of the shoes adjacent the brush l2. If it is desired to ymerely buff the shoes without application of polish, the proper coin is next inserted in the slot Sil and the operator may then slide the actuator 8S, S2 forwardly by grasping the upright portion 9|. This operation initially angularly displaces the pin 8l and the wheel 84, thereby effecting contact of the pin 85 with the plate 83 and starting the motor 35. As the motor continues to operate, motion from its shaft is transmitted by sprocket t5, chain 3l, pulley M, belt 4| pulley 42, shaft 32, pulleys t3, belts P15, and pulleys i5 to the shafts i9 of the brushes i, causing these brushes to rotate with the axial bristles thereof constantly urged against the opposite sides of the shoes It by means of the hinged and laterally-swingable Varms 2G and cooperable coil tension springs 25.

At the same time motion from the motor shaft is transmitted by sprocket 3B, chain 31, pulley Gil, belt 4l, pulley 42, shaft 32, pulleys 44, belts lll, pulleys'd, shafts Ml, sprockets .i, chains 5I, and sprockets 52 to the shafts 28 of the brushes i2, causing these brushes to likewise rotate with the radial bristles thereof constantly urged against the toes of the shoes lli by means of the swingable arms 2S and cooperable coil compression springs 3 l. Simultaneously, the sprocket 53 on the shaft 39 drives the chain 54 and the sprocket wheel 55, causing the shaft 56 and crank 5'! to rotate and thereby effecting oscillation of the brushes iii, l2 through the connection of the pitman 58 with the crank 51 and composite brackets 22. While the shoes l!! are thus thoroughly brushed by the rotating and simultaneously oscillating brushes il), l2, the oscillatory movement of the brackets 22 cause the pawl 94 to rotate the wheel 84 by increments through engagement with the peripheral teeth Q5 until the wheel 8d has made a complete turn and the contact pin 8e reaches the gap in the plate St, at which time the switch is opened and further operation of the motor and brushes ceases.

If it is desired to receive a complete shine from themachine, including the application of polish, the proper coin must rst be inserted in the slot provided in the member H32 and the actuating member H32 then slid forward as described with reference to the actuator 73S. As the actuator |02 is moved forwardly, the lug H33 engages the shoulder lili on the member 89 and pushes the member 8e, 92 therealong, thus angularly displacing the pin 8l and starting the motor 35 and series of operations hereinabove described. In addition, the portion Het of the actuator engages an arm of the bell crank liiii, causing the bell crank ll to shift the shaft IM' toward the wheel As the wheel 55 rotates the lug Il thereof contacts the end of the crank |69, causing the shaft lill to rock clockwise with the trip lever H9 thereby engaging the latch lZ which holds the lever H9 and shaft lli'i in tripped and latched position. As the shaft lill is angularly displaced or rocked as above set forth, the arm IH is also rocked, thereby moving the rod l l2 and its actuating connections '52, 'i6 to the right and rotatingthe plates HE, l le for actuating the Valves 1l, 15 respectively to valve opening position, the valve 'El opening only momentarily, due to the coaction of the arm l2 with the notch lll of the plate H5 and simultaneous action of the spring H8, to permit a slug of polish from the receptacle 68 to enter the pipe and the valve l5 remaining open, due to the pivotal connection of the arm 16 with the plate 5&6, a sufficient length of time to empty the pipe 'i3 of polish by ejector action of the compressed air passing through the pipes TI, i8. During this valve actuating operation, the motor 35 is driving the compressor 54 through the sheave 5l, belt t2, and sheave 63 and compressed air is being delivered through the pipe 65, tank 66 and pipe @l to the upper portion of the polish receptacle ES. Consequently as the valve 'H is opened momentarily as aforesaid, a slug of polish from the receptacle is forced into the pipe 13 by air pressure in the receptacle; and as the Valve 'i5 is maintained open, air under pressure delivered by the pipe El and thence through the pipe lil, valve l5, and pipes il, 'i8 draws the polish from the pipe it and delivers the same to the brushes i2 through the nozzles i9, 80. As the wheel Se rotates as above-described, the lug Effi contacts an arm of the latch l2i), pivoting the latch and disengaging the trip lever H9, the spring 22 then turning the shaft lill and arm i i i to its original position and causing closing of the valve Although the polish delivering means is thus rendered ineffective, the brushes, iii, i2 continue to operate on the shoes I4, being driven by the motor 35 until the wheel 84 has been caused, by the coaction of the pawl 94 with the teeth to complete a revolution and carry the Contact pin to the gap in the plate 83.

From the foregoing detailed description of the construction and operation of my automatic shoe shining unit it is apparent that my invention provides an improved coin actuated, motor driven machine which is adapted to effectively buff and/or polish shoes of any size. The improved machine is relatively simple and compact in construction and the polishing brushes are flexibly mounted so to receive and snugly contact either mens, womens or childrens shoes. The improved mechanism has proven highly successful in actual use and the unitary construction of the machine permits the same to be transported and installed in limited spaces. As is apparent from the foregoing detailed description, the machine is adapted to selectively perform two series of operations, one of which is a bufling operationonly, without application of polish, and the other of which is a combined bufng and polishing operation. With the improved mechanism, the motor is adapted to drive operating mechanism for the brushes as well as the compressor for delivering polish by fiuid pressure means to the brushing zone. The rotating side brushes are all adapted to be constantly resiliently urged toward the opposite side portions of the shoes, and the toe brushes are adapted to be urged toward the toes of the shoes, and these brushes are all moved over the entire surface of the shoe by the oscillatory motion hereinabove described. The various parts of the machine may be so arranged as to operate for a given period of time and with a predetermined amount of polish adapted to be automatically conducted to the polishing zone during the full polishing operation. One of the selected series of automatic operations may obviously be initiated upon insertion of a coin of given denomination, for example, a nickel, and the other series of automatic operations may be initiated upon insertion of a coin of a different denomination, for example, a dime. The improved machine is durable in construction and all of the parts have been found to require minimum attention, but if it is necessary to repair or replace any parts, the parts are all conveniently accessible.

It should be understood that it is not desired to limit this invention to the exact details of construction or precise mode of operation herein shown and described for various modifications within the scope of the appended claims may occur to persons skilled in the art to which this invention pertains.
