SHOE-SHINING MACHINE.

Application fllcd October 28, 1921. Serial No. 511,327.

My invention relates more particularly to improvements in shoe shining machines of the type which operate to automatically first brush the shoes to prepare them for receiv- 5 ing the polish, and thereafter apply the polish and brush the shoes to produce the desired polished surface; and my primary obj cots are to render machines of this type better adapted for performing their functions and to provide a comparatively novel, simple and inexpensive construction of machine and one which will be positive and effective in operation; and other objects as will be manifest from the following description.

Referring to the accompanying drawings: Figure 1 is a view in rear end elevation of the machine. Figure 2 is a plan sectional view of the machine, the section being taken at the line 22 on Fig. 3 and viewed in the direction of the arrows. Figure 3 is a vertical sectional view of the machine taken lon gitudinally thereof, at the line 3-3 on Fig. 2 and viewed in the direction of' the arrows. Figure 4 is a section taken at the line 4-4 on Fig. 3 and viewed in the direction of the arrows. Figure 5 is a section taken at the line 5-5 on Fig. 2 and viewed in the direction of the arrows. Figure 6 is a section taken at the line 66 on 39 Fig. 7 and viewed in the direction of the arrows. Figure 7 is a section taken at the irregular line 7-7 on Fig. 6 and viewed in v the direction of the arrows, this figure being a continuation of Fig. 3 and showing the upper portion of the machine omitted from the last-referred-to figure; and Fig. 8 18 a section taken at line 88 on Fig. 7 and viewed in the direction of the arrows. T he frame of the machine is represented at 10,

this frame supporting the various operatmg mechanisms as hereinafter described, the machine being -formed with a shoe-rest repre sented at 11 conforming generally to the shape of the bottom of a shoe and providing the upper substantially horizontal plate-llke portion 12 carried by the vertically-disposed platelike portion 13 provided at its forward and rear ends with shafts 14 extending laterally in opposite directions beyond the plate-portion 13 and carrying rollers 15 which extend into, and are movable along, channeled guide bars 16 secured to the frame of the machine and extendinglongitudinally thereof, whereby the shoe-rest 11 is adapted to be reciprocated, the means shown for this purpose comprising a link 17 referably of the shape shown in Fig. 3 whic is pivotally connected at 18 with the rear end of the plate portion 13, a crank 19 pivot'ally connected at 20 to the other end of the link 17, this crank being carried by a" shaft 21 journaled in a bearing 22 carried by the frame of the machme, and means for rotating the shaft 21, these means comprising a worm-wheel 23 secured to the shaft 21 and meshing with a worm 24 secured to a shaft 25 journaled in a bearing 26 on the frame of the machine, the 'shaft 25 being provided with a worm wheel 27 which meshes with a worm 28 fixed on the main drive shaft 29 journaled in bearings 39 and 31 on the frame and driven in any suitable way as through the medium of an electric motor 32 mounted on theframe of the machine and connected with the shaft 29 through the-medium of sprockets 33 and 34 on the shaft 29 and armature shaft of the motor 32 respectively, and a sprocket chain 35 connecting these sprockets together, the motor 32 being started and stopped in any suitable manner, as through the medium of a switch (not shown). It will be understood from the foregoing that when the motor 32 is operated, the shoe-rest will be reciprocated, the gearing between the motor and the shoe rest being preferably such that the latter will be given a relatively slow movement.

The machine also comprises a series of brushes, two represented at 37 and 38, respectlvely, being arranged at opposite sides of the shoe-rest which latter is preferably coincident with the center line ofthe machine, another adjacent the toe end of the shoe restand represented at 39 comprising a toe brush, and a fourth brush represented at 40 located adjacent the heel end of the shoe- 95 rest and forming a heel brush.

The

brush devices

37 and 38 are of the same construct-ion, each comprising an endless flexible brush proper 41 formed of an endless strip or Web 42 supporting the bris- 100 ties 43, which are preferably so arranged as to afford spaces 43 at intervals, each web 42 being mounted upon and surroundinga pair of grooved rollers 44 and 45 fixed on the upper ends of

studs

46 and 47 journaled 105 in bearings 48. projecting laterally from .members 49, the members 49 being rotatably mounted, independently of each other, on the shafts 50 mounted in upwardly-extending brackets 51 carried by the frame of the machine, the members 49 being provided with fins 52 projecting lengthwise of the machine, the fins 52 of each set of the arms 49 extend.- ing in a direction toward each other but being spaced apart as represented more clearly in Fig. 4.

The members 49 at the right-hand side of the machine in Fig. 3, while rotatably mounted on the shaft 50 are prevented from sliding lengthwise of the latter by any suitable means such as for example by pins 49 one for each of said members 49, which extend into annular grooves (not shown) in the peripheries of shafts 50, whereas the others of'the members '49 are not only rotatable on shaft 50 but are slidable thereon len thwise of this shaft.

Extending between the members 49 at each side of the machine, are bars 53 the ends of which are bifurcated as represented at 54, at which port-ions they loosely straddle the adjacent fins 52, the bars 53 being pivotally connected between their ends as indicated at 55 to bars 56 which are confined, to extend crosswise of the machine, in guides 57 carried by the frame of the machine, the inner ends of these bars being provided with rollers 58 cooperating with cams 59 provlded on the plate portion. 13 of the shoe-rest. The

brush devices

37 and 38 are thus supported in amanner to permit them to rock independently of each other toward and away from the center of the machine, springs 60 connected with the guides 16 and with the members 49 serving to yieldingly swing these brush devices toward the center line of the machine except as restrained by the engagement of the rollers 58 with the cam surfaces 59 or with the sides of the shoe, during the operation of the machine, as hereinafter described, it being also understood from the foregoing that by reason of the connections between the bars 56 and themembers 49 and the supporting of the latter independently of each other on the shafts 50,-each brush is capable of deforming to cause it to conform to the surface of the shoe traveling against it.

,The upper ends of the sets of members 49 cooperate with springs 61 confined therebetween as shown in Figs. 2 and 3, these springs serving to force the sliding ones of the members 49 of each set thereof in a direction away from those of the members 49 containing the pins 49 and thereby maintain the webs 42 in taut condition to permit them to be driven as though the medium of pulleys 62 mounted on the lower ends of the shafts 47, these pulleys being connected with pulleys 63 on the shaft 29, as by means of the belts 64, the operative driving connections referred to being such that the

brushes

37 and 38 will be driven in the direction of the arrows 65 andshaft-.67 supported in bearings 68 provided on the outer ends of a pair of arms 69, the other ends of which arerotatably mounted at 71 on a shaft which latter is journaled in bearings on the frame of the machine, the shaft 67 carrying a pulley 72 connected by a belt 73 with a pulley 74 connected with the shaft 70 and driven by a belt 75 engaging the pulley 74 and a pulley 76 on the drive shaft 29, the parts being so arranged that the brush 39 is rotated in the direction of the arrows 77 in Figs. 2 and 3. The support for the brush 39, and comprising the arms 69, is thus swingingly mounted, and springs 78 connected at their upper ends with the frame of the'machine and at their lower ends with the respective arms 69, are preferably provided for preventing the brush 39 from swinging below the position shown in Fig. 3.

The heel brush 40 is also of general cylindrical type, it being supported on a shaft 79 journaled at its ends in spaced arms 80 which are swingingly mounted at their lower ends on a shaft 81 journaled on the frame of the machine. The shaft 79 is providedwith a pulley 82 driven by a belt 83 from a double pulley 84 on the shaft 81, this double pulley being driven by a belt 85 from the pulley 86 on the main drive shaft 29, the parts being so arranged that the brush 40 will be rotated in the direction of the arrow 86 in Fig. 3. Connecting the arms 80 is a cross-piece 88 which with the arms forms a rigid member in the form of a frame, this frame bein connected with one end of a spring 87, t e rear end of this spring being connected with the shoe rest 11 and operating to' swing the supporting frame for the brush 40 to the right in Fig. 3. The frame last-referred-to engages at its crossbar 88, in the normal position of the machine (Fig. 3) with a surface 89 on the heel end of the shoe rest which normally holds the frame carrying the brush 40 in the position shown in Fig. 3, itbeing understood that as soon as the shoe-rest starts to move to the right in Fig. 3 toward the rear end of .the machine,

til

this brush will follow up the movement of the shoe-rest to cause it to operate in contact with the heel portion of the shoe to be cleaned and polished. In the particular construction illustrated the machine is provided with means whereby either black or tan polishing fluid may be applied to the shoe, as desired, the tanks in which these fluids are contained being represented at 90 and 91, these tanks being connected at their lower ends with

outlet pipes

92 and 93, respectively, said pipes being equipped with

valves

94 and 95 respectively. These valves are shown as of the slide type, and the stems of the valves proper thereof are represented at 96 and 97, and have enlarged ends as represented at 98 and 99, respectively.

Mounted on the frame of the machine adjacent the

valves

94 and 95 is a casing 100 lengthwise-f this casing and is also movable transversely thereof, this block being backed up by coil springs 102 confined between the block and the wall of the casing and operating to normally hold the block in the position shown in Fig. 8. The block is of such proportions that it may be shifted to extend opposite either one of the valve stems 96 and 97, it being shown opposite the stem 97 in Fig. 8, the means provided for thus shifting the block comprising a lever 103 of bell-crank shape pivoted at its angle on a shaft 104 mounted on the frame of the machine, one end of this lever containing an elongated slot 105 into which a pin 106 on the block 101, extends, the opposite end of this lever being accessible for actuation by the operator who by rocking the lever 103 shifts the block 101 lengthwise either to extend opposite the valve stem 96 or 97 depending upon the direction in which the lever is rocked, the purpose of this part of the construction being to so position the block that when the block is actuated transversely of its length and against the action of the springs 102, as hereinafter described, the one of the valve stems 96 and 97 desired to be operated, is actuated to permit polish from the tank controlled by this particular valve, to flow through the outlet of the tank into the pipe system hereinafter explained. The mechanism shown for operating the block 101 against the action of the springs 102 comprises a reciprocating bar 107 extending through a slot 108 in the casing 100, the lever 103 also being shown as extending through this slot, one end of the bar extending through an elongated slot 109 in the block 101, the inner end' of this bar being headed as represented at 110. The other end of this bar is pivotally connected at 111 with the upper end of a lever 112 fulcrumed between its ends, at 113, on a stud 114 mounted in a bracket 115 dependingly secured to the stationary frame of the machine, the lower end of the lever 112 extending into the path of movement of a roller 116 journaled in a bracket 117 mounted on one face of a disk 118, this disk being fixed on the end of a shaft 119 journaled on the frame of the machine and provided with a sprocket 120 connected by a sprocket chain 122 with a sprocket. 121 fixed on the shaft 21, it being understood from the foregoing that each revolution of the disk 118 causes the roller 116 to engage the lever 112 with the result of rocking it in counter-clockwise direction in Fig. 6, on its pivot 113, thereby forcing the block 101 to the left in Fig. 8 against the action of the springs 102 and opening the particular one of the

valves

94 and 95, which it opposes, these parts being preferably so constructed and arragned that the particular valve opened will remain open for a length of time sufficient to permit of the desired amount of the polish contained in the particular tank it. controls, to discharge therefrom past the valve.

The pipes 92 and'93 open into a pipe 123 which opens into a distributing tube 124 in communication with

pipes

125 and 126, the pipe 125 terminating in a nozzle portion 127 which extends across the periphery of the heel brush 40, the nozzle portion of this pipe containing a series ofperforations (not shown) which open toward the brush whereby the polish dlscharging from this nozzle will be sprayed upon the brush preferably substantially throughout the width of the latter. The pipe 126 terminates in a similar nozzle portion 128 which extends across the periphery. of the toe brush 39 for supplying polish to this brush.

The pipe 125 has branch portions l30 which terminate in nozzle sections 131 secured to the discharge ends of these branches, these nozzles, which may be of the same construction as that above described of the nozzle 127 extending crosswise of the

brushes

37 and 38, respectively for supplyingi polish to these brushes.

he machine also comprises means for introducing into the pipe 123 blasts of air for forcing the polish through the pipe systern described and out through the said nozzles, and also for the purpose of exerting a drying action on the brushes after the polish has been applied to the shoe, these means,

in the particular construction shown comprising a tank 132 supported on the frame of the machine and connected with a pipe 133 leading from the discharge end of an air com ressor 134 also mounted on the frame 0" the machine and driven from the drive shaft 29 as through the medium of a sprocket chain 135 passing, over

sprockets

136 and 137 connected with the shaft of the compressor and with the shaft 29, respectively. A pipe 138 communicates at its 0pposite end with the pipe 123, the pipe 138 containing a valve 139. The valve 139 is of the same type as the

valves

94 and 95, and extends into the path of movement of a series of rollers 140 journaled in brackets 141 mounted on the face of the disk 118 opposite that carrying the bracket 117, the rollers 140 being spaced apart and so arranged that they will not engage the valve 139 to open it, until the shoe-cleaning operation has been effected, which latter, in the particular construction illustrated, involves a complete reciprocation of the foot-rest.

The operation of the machine is as follows:

Assuming that the machine is in the normal position shown in the drawings Wherein theshoe-rest occupies its extreme position to the left in Fig. 2, and the cams 59 have engaged the rollers 58 and forced them outwardly in opposite directions in Fig. 4, to

move therewith permitting the springs 60 to swing the side brushes 37 and 38 into engagement with the opposite sides of the shoe and the heel brush 40 is also permitted, under the action of the spring I 87 to swing to the right in Fig. 3 and into engagement with the heel portion of the shoe, the toe brush39being yieldingly supported, riding upon the toe portion of the shoe as the shoe travels rearwardly, the various brushes referred to operating, in the first complete reciprocation of the shoe rest, to thoroughly brush off the shoe preparatory to the application of the polish thereto. During this first complete reciprocation of the shoe rest, the roller 116 is caused, by the rotation of the disk 118 to engage the lever 112 for opening the one of the valve devices 94 and 95' opposing the block 101, the operator having previously, through the medium of the lever 103' positioned this block for'operating the desired one of these valves. A charge of the polish is thus permitted to discharge from one or the other of the tanks 90 and 91 from which it runs down into the pipe 123. Preferably immediately following the swinging of the side brushes into engagement with the shoe upon the next rearward movement of the shoe-rest following the shoe-cleaning operation, one of the rollers 140 engagesthe valve 139, opening the latter and permitting a blast of air from the tank 132 to flow through the pipe 123 which forces the polish supplied to this pipe, as hcreinbefore stated, out through the various nozzles referred to and against the faces of the various brushes, and thus during this second complete reciprocation of the shoe-rest, the various brushes apply polish to the various surfaces thereof to be polished; During the next and last complete reciprocation of the shoe-rest, the brushes operate to polish the surfaces to which the polish was applied. The rollers 140 are provided in a series, to successively actuate the valve 139, not only to insure the blowing of all of the polish from the. pipes. but also for the purpose of exerting .afdrying action on the brushes after the latter have applied the polish to the shoe. In the particular ar= rangement shown this drying action is com menced before the shoe has returned to normal, start ng position in its second complete reciprocation, but it will be understood that the timing of'the blasts may be varied as each time the shoe rest nears theend of its return movement and thus tendency of these brushes to heat the shoe is minimized. The feature of providing the spaces 42* at intervals along the bristle-surface thereof also reduces the tendency to heating of the shoe.

While I have illustrated and described a particular construction embodying my invention, I do not Wish to be understood as intending to limit it thereto as the same may be variouslymodified and altered without departin from the spirit of my invention.
