Like characters of reference indicate like parts in the various views.

In the drawmgs 1 designates a body in which themechanism is housed. A platform 2 is provided at the front end of the body, and a seat 3 is built upon the body facing the platform 2. An aperture 4 is formed in the platform 2 in a convenient position relative to the seat 3. A pair of shoe supports 5 are located in the body directly underneath the aperture 4 and are adapted to conveniently support the shoes of a person sit ting on the seat 3. The shoe supports 5. are are secured to a bottom ,6 of the body 1. Said shoe supports 5 are formed to engage the underside of shoes 7 resting thereon, and have projections 8 formed thereon adapted to engage the front end of the heel of the shoes to properly position the shoes upon said shoe supports.

It will be noted, by reference to Figs. 2 and 3 of the drawings, the body 1 isdivided into a number of compartments bg' partitions and to protect the various mec anisms located therein and to afford means for conveniently securing said mechanism in the body. A transverse vertical partition 9 is disposed within the body adjacent the rear edge of the aperture 4. ,A horizontal transverse portion 10 is disposed within the body some distance below the top of the shoe supports 5, and a secondhorizontal transverse partition 11 is formed in said body in the plane of the platform 2. These partitions are cut away at various points, as will be hereinafter described to allow the various parts of the mechanism to operate therethrough.

A shaft 13 is disposed transversely of the body and is mounted upon bearings 14- secured to the upper surface of the partition 10. Disks 15 are mounted upon opposite ends of the shaft 13 and constitute fly-wheels, for the mechanism. A pair of guides 16 are mounted upon the partition 10 and extend longitudinally of the body in front of'the disks 15. A block 17 is mounted in each guide and is adapted to move thereon. A pit-man rod 18 is provided for each block that the inclosure of and has its" front end'pivotally mounted upon said block and its rear end pivotally mounted u on a stud 19 secured upon the respective isk 15. Rods 20 have their rear ends secured to their respective block 17 and extend forward thereof through anaperture 21 of the guide structure. The front ends of the rods 20 are bifurcated, as designated at 23, and lie in a horizontal plane. A brush member 24 is pivotally mounted for horizontal swinging movement on each arm of said bifurcated ends 23. The bristles 25 of each brush member 24 are disposed upon the side thereof facing the brush mounted upon the opposite arm of the bifurcated end. Flat spring members 26 are mounted upon the outer side of each arm of the bifurcated end, and extend forward therefrom to engage the brush members 24 and to retain each pair thereof in close relation with each other. A coil spring 27 is also provided to retain each pair in close relation with each other. and has its ends secured to the opposite brush members 24. Stops 27 are formed on each arm of said bifurcated ends 23 to limit the movement of the brush members 24. ,When the shaft 13 is rotated the brushes 24 are reciprocated, and are so disposed that they will engage the sides of a pair of shoes resting upon the shoe supports 5 with their bristles 25. The bristles 25 are formed so that they will engage all of the lower surfaces of the shoes.- It will be noted in this re ard that the front and rear portions of the ristles 25 are relatively longer, as designated at 28, so that in the reciprocations of the brushes 24 these longer brlstles will engage the rear and front surfaces of the shoes and 'will thereb engage the entire lower surfaces of the oes. By reason of the fact that the brushes 24 have a hinged relation with their mates, the brushes will accommodate themselves to various sizes of shoes. An aperture is formed in the partition 9 to allow the brushes 24 to reciprocate as herein described.

A motor 12' is mounted upon the upper surface of the partition 11 and has a sprocket 29 mounted upon its rotating shaft 30. A sprocket 29 is mounted upon the shaft 13 adjacent disk 15 in alinement with said sprocket 29, and a chain 31 is trained over said sprockets to form a driving connection therebetween. Mounted upon the shaft 13 is a spur gear 32. A shaft 33 is mounted in bearings 34 which are formed in respective extensions of the structure of the bearings 14. A spur gear 35 is ournaIed upon said shaft 33 and meshes with the gear 32, said gears 32 and 35 being equal in size. Mounted upon the shaft 33 is a miter gear 36. A vertical shaft 37 is journaled in one of the extensions of the structure of bearings 14, and a miter gear 38 is mounted upon the upper end of said shaft and meshes with end of the shaft 37 and meshes with a miter gear 43 mounted upon the rear end of the shaft 39. i

The front end of the shaft 39 has a gear 44 mounted thereon. A shaft 45 has its rear end journaled in the structure (if the bearing 41, and has a gear 46 meshing ,with the gear 44. The gear 46 is considerably larger than the gear 44 for purposes hereinafter described. A double faced cam 47 is mounted upon the shaft 45 some distance in front of the gear 46. A cam groove 48 is formed upon the rear surface of the cam 47, and a cam groove 49 is formed upon the front surface of the cam 47. A cam lever 50 is provided, having a slot 51 formed therein engaging the shaft 45 between the gear 46.and said cam 47 and having a roller-52 rotatably mounted thereon' and engaging the cam groove 48. The cam lever 50*is suppor for horizontal sliding movementby the sh 45, and aslide 53 formed upon the structure of bearing 41, and has a link 5.4 pivoted for horizontal swinging movement; at its outer end. A bellows 55 of usual construction is mounted upon the adjacent side of the body andis operated through the link 54. A cam lever 56 is disposed infront of the cam 47. and has a slot 57 engaging said shaft 45. A roller 58 is rotatably mountedon said cam lever and engages the cam groove 49. Said cam lever 56 is supported by said shaft 45 and a slide 59 formed upon the structure of the bearing 60 in which the front end of the shaft 45 is journaled. The cam lever 50 is confined laterally between the rear surface of the cam 47 and the front surface ofthe gear. 46. A gear 61, identical with the gear 46, is mounted upon the shaft 45 just in the rear of bearing 60 for purposes hereinafter described, and the cam lever 56 is confined between the rear surface of saidji' gear 61 and the front surface of the cam 47. The cam lever 56 extends toward the other side of the body and has a link 62 mounted on its outer end for horizontal swinging movement. A bellows 63 of usual construction is mounted upon the adjacent side of the body, and is in operable connection with said link. The bellows 55 and 63 comprise stationary bottom members 64, movable top members 65 having one end hinged to said bottom members, flexible folding side elements 66 forming an inclosure with said top and bottom members, intakes 67 provided with check valves, and outlet pipes 68 provided with check valves. The bellows 55 and 63 are actuated by the cam 47 through the medium of 'tarial drivin' the cam levers 50 and 56 and the

links

54 and 62, and, by reason of the contour of the

cam grooves

48 and 49, are adapted to be actuated at different times for purposes hereinafter described.

A movable frame 69 is mounted upon the bottom 6 of thebody for longitudinal sliding movement. This movable frame comprises a horizontal portion 70 and uprights 71 extending upwardly therefrom on either side of the horizontal portion. A transverse shaft 72 is journaled upon the uprights 71. A vertical shaft'7 3 is journaled on .a bracket 74 of the frame 69 and has a bevel gear 75 mounted u on its upper end and meshing with a beve ear 76 mounted upon the transverse shaft 2. Another bevel gear 77 is mounted u on the lower end of the shaft 73. A hearing 78 is formed upon the horizontal portion 7 0 of the movable frame and su ports the front end of a shaft'7 9 disposed in alinement with the path of the frame 69. A bevel gear is mounted upon the front end of said shaft and meshes'with the bevel gear 77. A thrust collar 81 is mounted upon he shaft 79 and engages the rear surface of he bearing 78, and the shaft 79 is secured gainst lateral movement said collar and the bevel gear 80 which engages the front surface of said bearing. A bearing 81 is mounted upon the artition 9 in axial alinement with the sha t 79. A sleeve 82 is journaled therein and has thrust collars 83 mounted thereon on either side of said bearing to prevent lateral movement. The rear end of the shaft 79 engages the front end of the aperture in said sleeve and is adapted for sllding movement therein. A key 84 is secured to said shaft and engages a longitudi-nal slot in said sleeve to provide a rotarial driving relation between said sleeve and said shaft. A shaft 85 engages the rear end of the aperture in the sleeve 82 and is adapted for longitudinal sliding movement therein. A key 86 is secured to said shaft'85 and engages a slot in said sleeve whereby a rorelation between said sleeve and said sha t is obtained. The rear end of said shaft 85 is secured within the hole of a sleeve 87. -A bracket '88 is secured to the rear wall of the body and has a long stud 89 formed thereon in axial alinement with the shaft 85. The hole in the sleeve 87 is journaled u on said stud, and the rear end of said sha t 85 and the sleeve 87 are supported thereby. It will be noted that the shaft 85 and the sleeve 87 are adapted for longitudinal movement for purposes now to be described. A groove 90 is formed upon the outer surface of the sleeve 87. This groove forms a complete circuit comprising two parallel portions 91 formed spirally re specting the axis of said sleeve and semicircular portions 92 connecting .the respective ends of said parallel portions. A series .the sprocket other opposite parallel portion of the groove.

radially of the shaft 72.

of spaced pins 93 are secured upon the surface of said sleeve between the parallel portions of said groove and are disposed 1n a line equidistant from the parallel portions of said groove, the end pins of said series being disposed coincident with the centers of said semi-circular portions of the groove. vertical shaft 94 1s journaled upon the structure of the adjacent bearing 14 and has .alarge bevel gear 95 mounted at its upper end and a relatively small bevel gear 96 is mounted upon the shaft33 and meshes with said bevel gear 95. Mounted upon the lower end of the shaft 94 is a sprocket gear 97, the teeth of which areadapted to engage the successive pins in the series of pins 93. The lower end of the shaft 94 extends below the sprocket gear 97 and engages the groove 90 in the sleeve. When the shaft 94 is rotated the sprocket gear 97 engages successive pins in the series of pins 93 and rotates the sleeve, and the sleeve, by reason of the inclination of the roove 90, is also moved longitudinally. hen the sprocket gear 97 engages the end pins of. the series and the shaft 94 enters the corresponding semi-clrcular portion of the groove. As the shaft passes through the semi-circular portion of the groove the engaged pin is swung around gear and the shaft enters the The rotation of the shaft is reversed in this operation and the sleeve is rotated in the opposite direction until the other scmi-circular portion of the groove is reached where the reversing operation is repeated. By the mechanism above described a means is provided'for driving'the shaft 85 alternately in opposite directions for purposes hereinafter set forth.

Pivotally mounted upon the transverse shaft 72 just inside the bearings of the uprights 71 are brackets. 98. Said brackets 98 have bearings 99 formed therein disposed Shafts 100 are ournaled in said bearings 99 and have bevel gears 101 mounted upon the inner end thereof and engagin respective bevel gears 101 mounted upon t e shaft 72. The brackets 98 extend along the shafts 100 and support the outer ends thereof in bearings 102. A yoke 103 is pivotally mounted upon the shaft 72 at a point intermediate the ends thereof and has a rod 104 secured in a recess therein. The rod 104 has a bracket 105 secured thereon, a strut rod 106 secures the outer ends of each bracket 98 with said bracket 105. The rod 104 and the shafts 100 lie in the same plane. A shoulder 107 is formed upon the shafts 100 and engages the outer surface of the bearings 102, and the shafts are secured against lateral movement between said shoulder 107 and the outer face of the gears 101. A spool 108 is rotatably mounted upon ball bearings 109 on the outer ends of the shafts 100. A spiral spring 110 encircles each shaft 100 within the spools 108, and has its one end secured to .its respective shaft and its other end secured to its respective spool whereby a resilient driving connection is established between the shafts .100 and their respective spools. The spools 108 have deep flanges formed at their ends. A flexible belt polishing element 111 has one end thereof secured to each respective spool and is of such length that a large portion may be wound upon either of the s ools. The ends of this flexible belt polishmg element are detachably secured to the spools by means of a plate 112 and headed screws 113 which clamp the ends of the belt element between the plate and the body of the spool. In applying a polishing belt element upon the spools the springs 110 of the spools are held sufficiently taut so that they tend to wind the belt element upon their respective spools. This winding tendenc is transmitted to the portion of the be t polishing element which extends from one spool to the other and it is stretched taut thereby. The

rod 104 has an idle spool 114 journaled upon its end and lying in the plane of the spools 108. This spool contacts the belt polishing element at a point intermediate the spools 108. Casings 115 partially inclose the spools.108 to prevent the belt olishing element from jumping over 'the the spools, and are secured upon the. bearings 102. 1

It will be noted that a tilting frame is formed by the above described structure, comprising brackets 98, bracket 105, the yoke 103, the rod 104, and the strut rods 106, which is pivoted upon the shaft 72. The

osition of this tilting frame is controlled in the following manner. On the under side of .the bracket 105 a pivot bearing 116 is formed. A cam lever 117 has its upper end pivoted in said bearing 116 and extends downwardly. A shaft 118 is journaled in a bearing 119 which is mounted on the horizontal portion 70 of-the movable frame 69,

said shaft being disposed parallel to the path of movement of said frame69 and lying in axial alinement with the shaft 39 hereinbefore described. The cam lever 117.

has a slot formed in the lower end thereof which embraces the shaft 118 and the lower end of said cam lever is guided thereby. A

anges of rearwardly and engages a bearing 126 in' the bearing structure 60, and extends through the bearing 126 and has a gear 127' mounted thereon at the rear of the bearing and meshing with the gear 61 hereinbefore described. The gear 127 engages the rear surface of the bearin is secured on the sha in front of the bearing 126 and enga es the front surface thereof, and the sha is held against lateral movement thereby. The gear 127 is the same size as the gear 14.. By reason of the fact that the gears '44 and 127. are the same size and that the

gears

16 and 61 are the same size, the shaft 124 and the shaft 39 will rotate at the same speed.

A clutch collar 129 is slidably keyed upon the shaft 33.- Said clutch collar has a projection 130' upon the sideadjacent the gear 35 which is adapted to engage a projection 131 formed upon said gear 35 when the clutch collar is moved toward said gear 35. Thus, it will be noted, that a driving connection is established between the shaft 13 through the engagement of the clutch collar 129 with the pro]ection 131 on the gear 35. The bellows 55 and 63 are also driven through the clutch collar 129 for purposes hereinafter described.

.A polish reservoir 132 is secured upon the partition 9 on either side of the shoe supports 5. Another polish reservoir 133 is mounted upon said partition 10 between the shoesupports. A pair of polish reservoirs 134: are mounted upon the movable frame 69 in front of the shoe supports 5. The

polishreservoirs

132, 133 and 134 are adapted to contain liquid polish and are disposed in the same horizontal plane and a number of pipes 135'inter-connect them so that the polish therein will distribute itself throughout all of the reservoirs and maintain an equal level of polish therein. The pipes 135 which connect the

polish reservoirs

132 and 13 1 are flexible so that. the frame 69 may be moved. A filler pipe 136 leads through the wall of the body from one of the reservoirs 132 for filling the polish reservoirs from the outside of the body. A number of vertical pipes 137 are disposed in the polish reservoirs and have their upper ends open and extending above the side walls of the reservoirs, see Fig. 12. Each pipe 137 has a noz A shaft 126 and a collar 128 and the spools 108, and the cam'lever 117 was -.zl'e of an- -a-ir .pipe 138 disposed-adjacent fthe out-of the nozzles so that the. polish-is drawn upthrough the .pipes 137 and sprayed-upon shoes resting on said shoe supports.

dust and an air circulating mechanism is disposed above the brushes and has its intake 143 disposed adjacent the agitating members 141 so that :the dust laden'a-ir passes intovthe air intake 143. The-air'cir- -'culating mechanism 142 is of usual construction and comprises .a rotary fan 144.: disposed within the casing 145 and, driven by an electric motor .146. The ca'sing145 communicates with the intake 143 and has an outlet 147 which leads intova bag- 148 When the fan is rotated the air is taken into the intake and .passes through the casing 145 and outlet 147 into the bag 148 and through the sides of the bag leaving all dust, 'held in suspension, within the bag.

Journaled in bearings 149, which are secured upon the sides of the body 1, is a controlling shaft 150. This shaft is driven from the shaft of the motor 12 through a reducing gear train 151, whereby thec'ontrolling shaft makes one revolution for a complete operation of the machine. Mount ed upon the shaft 150 is a cam 152 which has a relatively small raised portion 153 thereon. A bell crank lever 154 is pivoted upon a bracket 155 which is secured to the partition 11. A cam roller 156 is mounted upon one arm of the bell crank lever and engages the surface of a cam 152 mounted on said shaft 150. A connecting rod 157 is- -.ductor"173.' .the conductor 173 to one terminal of the g the other "terminal of said motor 146 to a .Z'15'9 isap ivotallyconnected.to the lower end of the .conne'ctin gprod 15.7. and cam 152 con} -trols the position of the clutch rcol lar 129 cate with the outlet 69 of the bellows 55. v

As .is designated in Fig. 3, the contact- 162. A 'brush 171zeontacts-said brush wheel and a conductor 17:2 leads therefrom 'to one terminal of the motor 12. The otherterminal of the motor 12- is connected to the. source of energy 168 by means. of. con- A conductor 1'74 leads {from motor 146. A conductor 175 leads from I16 stationary cont-act 176 which isad'apted to .be engaged by a contact 177 mounted upon an extension of .the bell crank lever 154. Thecontact=177 is in electrical commun1ca tion with the brush wheel 170 by means of a conductor 177' for purposes hereinafter described. The contact portion of the arm 162 and the brush WM 170 and the contact 177 are insulated from the controlling shaft 150 as designated.

The operation of-the device is'as follower A person wishing his shoes polished sits in the seat 3' and places his shoes upon the shoe supports 5. He then operates the handle 166 to contact the lever 165 with the arm welever-I and the segmental ring 163'are in metallic contact with each other by means of-a conductor .1167. The conductor-1 67 is I connected with a source of electric ener' .-168 hy-=means of-a conductor 169. A brush wheel 17.0 isf'fo'rmed'on'the hub of-lthe a'rm 162. Said arm 162 always comes to rest over the gap 164 of the segmental ring 163 to stop the mechanism by reason of the fact that current is cut ofl from the motor 12 when the arm 162 passes over the gap 16-1. The circuit is closed when the contact lever 165 contacts the arm 162 and the motor 12 is started. The shaft 150 driven by the motor rotates the arm 162 and said arm soon passes beyond the gap 164 and engages the segmental ring 163 whereupon the handle 166 may be released to move the contact lever 165 to an inoperative position. The cam 152 is so positioned relative to the arm 162 and the gap 164 of the segmental ring 163 that the raised ortion 153 of the cam engages the cam rol er 156 as the arm 162 passes through the gap 164 so that uponthe initial rotation of the motor 12 the clutch collar 129 is positioned out of engage ment with the projection 131 of the gear 35,

and the shaft 33 remains stationary. Whilethe bell crank'lever 154 is in this position the'motor12 actuates only the brush members 24, and said brushes serve during this initial operation to brush the shoes and remove -dus't' and. dirt therefrom. While the bell crank lever 154 is in this position the contact 177 is in engagement with the con- =tact176 and a circuit is complete through the motor 146 whereby the air circulating means is actuated to gather dust removed from the brushes 24 and from the agitating members 141. As the motor 12 contlnues to rotate the cam 152 moves so that the roller 156 engages the lower portion thereof,

' whereupon the clutch collar 129 is moved 4-0-=of engagement with the contact 176 thereby into engagement with the projection 131 of thegear 35, and the contact 177 moves out stopping the air circulating mechanism 142. As the motor 12 continues to revolve the

shafts

39 and 85 are rotated and their connected parts actuated. When the clutch 129 is in engagement with the projection 131 the

bellows

55 and 63 are actuated to force air through their respective air pipes 138 to s ray polish upon the'shoes as hereinafter escribed. As above stated the bellows actuate the sprayers of the reservoirs 132 and 133, which spray polish upon the sides of the shoes. The actuation of the bellows 63 is so timed that polish is sprayed upon the shoes when the brush members 24 are Withdrawn from engagement with the shoes.

At this stage of the operation, the mechanism mounted upon the removable frame 69 is also actuated. This mechanism serves to supplement the brush members 24 in polishing the front of the shoes. The operation of this supplemental polishing means-is as follows. After each polishing operation, that is when the arm 162 passes over the gap 164 and the mechanism is stopped, the tilting frame rests in its upper position so that the opens the circuit to the motor 12.

shoes upon the shoe supports 5 may be withdrawn therefrom. A shield 178 extends over the

spools

108 and 114 to protect the same and. the belt element 111 as shoes are placed upon the shoe supports-or withdrawn there-f other and then to rewind it back. This movement of the polishingelement 111 is continuous during this stage of the operation of the mechanism and rubs the surface of the shoes as the cam 120 moves the tiltin frame to its lower position. By reason 0 the fact that the spools 108 have a resilient connection with their shafts a greater or less portion of the polishing element may be unwound from the spools so that the cam 120 may move the tilting frame to its lower position. When the

spools

108 and 114 are positioned below the shoes the polishing ele- V ment 111 is wrapped around the shoes, thus contacting practically the entire surface of the front of the shoes. See Fig. 4.

vWhen this supplemental polishing element is actuated the "bellows 55 is also operated to spray polish from the reservoirs 134 upon the front ends of the shoes, and the cam' groove 48 is so timed relative to the movements of the tilting frame that polish is sprayed from the reservoir 134 when the tilting element 111 is out of contact with the surface of the shoes.

The mechanism continues to be driven by the motor 12 until the arm 162 passes over the gap 164 of the supplemental ring i nd he motor then comes to a stop and the machine is set for another polishing operation.

The supplemental polishing mechanism, as above described, is mounted upon the movable frame 69.
