6 Claims.

This invention relates to shoe polishing machines, and -mort particularly to automatic machines of this character.

An important object of the invention is the provision in apparatus of this type of a construction which may be cheaply and durably fashioned and in which lubrication of many of the operating parts is effected through the polishing medium.

A further object of the invention is the provision of a novel and efiicient distributing means for distributing the polish upon the applying brush.

A further object of the invention is the provision of a construction in which separation of the constituents of the polish is impossible.

Another object of the invention is the provision of a construction whereby both polishing and polish-applying brushes may be operated from a single motor which likewise operates the several pumps necessary to' the apparatus, and further operates to cause one of the brushes to oscillate across the toe of the foot and the second brush to move about the foot.

These and other objects I attain by the construction shown in the accompanying drawings wherein, for the purpose of illustration, I have shown a preferred embodiment of my invention and wherein: 7

Fig, 1 is. a perspective view of apparatus con structed in accordance with my invention;

Fig. 2 is a view similar to that of Fig. 1 with the brushes and rotary plate removed;

Fig. 3 is a plan of the apparatus with the rotary plate removed;

Fig. 4 is a side elevation of the apparatus;

Fig. 5 is a section on line 55 of Fig. 3;

Fig. 6 is a diagrammatic view illustrating the pump connections;

Fig. 7 is a plan view of the distributor for the applying brush;

Fig. 8 is a side elevation thereof; and

Fig. 9 is a sectional view therethrough.

Referring now more particularly to the drawings, the numeral IO indicates a suitable support in which a stationary spindle l l extends vertically to rotatably mount organization l2 comprising the main control elements of the machine. This organization includes a central bushing l3 having bearing engagement at its ends with the spindle and having the central portion spaced from the spindle to provide an annular cavity i4. Near its lower end the bushing has a gear l5 formed thereon, and below this gear a worm gear I6 is secured to the bushing, such worm gear having upon its upper surface a cam I! the purpose of which will hereinafter appear.

Above the gear 15 a double pulley structure I8 is journalled and above the pulley I8 a hub I9 is secured to the bushing, such hub having a pair of arms and 2|. The arm 20 has secured thereto a disc 22 which axially rotatably engages the spindle II. The arm 2! has pivotally connected thereto at 23 a brush support 25. in the form of an arm having at its free end a brush. spindle 25. The upper end of this brush spindle, which projects through a substantially radial slot 26 in disc 22, mounts a brush 21. A foot support 28 is secured to the upper end of spindle l I and has a projecting cam rim 29 formed thereon. Supported from the brush spindle by upper and lower plates 30 and 3| is an arcuate segmental shield 32. This shield, through the lower plate 3!, supports a roller 33 which is adapted to engage against the cam rim of the foot support. A spring 34 connecting the brush support 24 and the hub 19 constantly urges the brush toward the foot rest, such movement being limited by the cam rim of the foot rest while the rotation of the brush tends to swing the segmental shield in the direction of rotation maintaining the roller 33 of the shield in engagement with the cam rim. The lower end of the brush spindle mounts a pulley 35 while the lower end of pivot 23 mounts a double pulley 36 one element of the double pulley being belt-connected with pulley 35 while the other element thereof is belt-connected to the upper element of the double pulley organization 18.

Mounted in upper and lower bearings 31 and 38 is a second vertical spindle 39, this spindle having at its upper end a horizontal yoke 40 providing bearings for a horizontal brush spindle 4| mounting brush 42. Projecting from the lower end of the spindle is an arm 43 the end of which Rotatably mounted upon spindle 39 is a pulley 4-8 at opposite faces 01' which friction cones 49 are disposed. The upper friction cone is engaged by a friction cone 50 mounted on a spindle 5| projecting horizontally from the spindle 39 and bearing a spring 52 for maintaining engagement iii between such friction cones. The hub of friction cone.50 comprises a pulley 63 belt-connected to a pulley 54 mounted upon spindle M. The numeral 55 designates a motor the armature shaft of which mounts a pulley 56 arranged in the common plane of the lower pulley of the double pulley I8, and the pulley 48, and a belt is trained around these pulleys and maintained in tensioned engagement therewith through a spring-pressed idler 5T.

Worm gear I6 is engaged by a worm 58 on a shaft 59 which shaft has a spring-pressed friction cone 60 engaging the lower friction cone 4!! so that upon operation of the motor the organization I2 is rotated as a whole and brushes 21 and 42 are driven at a relatively high speed. Mounted upon a stationary spindle 6| is a gear 62 meshing with gear I5, gear 62 being relatively large, say for example five times as large as gear I5. The upper and lower surfaces of this gear have cam tracks 63 and 64 receiving rollers upon yokes 65 and 66.' These yokes operate respectively the control valve 61 and pistons 68 of a measuring pump Bathe exhaust of which is connected through a conduit I0 and a port II formed in the lower end of the stationary spindle I I with the cavity I4. The upper end of cavity I4 is connected to the shield through a conduit I2 and the shield on its brush confronting face has an annularly-extending rib I3 which increases in width in the direction of rotation of the brush I and the conduit I2 discharges at the smaller end I4 of the rib.

Since the bristles of the brush will naturally engage more firmly with the shield at the rib 13, this rib acts as a spreading means for a-polishing medium delivered through the contact causing this medium to be distributed substantially uniformly over the surface of brush 21. This polishing medium, since it is stored in its passage in the cavity/I4 likewise serves to lubricate the bearing engagements between the spindle I I and bushing I3. Measuring pump 69 is supplied from a container I5 through medium of a rotary pump I6 secured to the end of shaft 59. Pump I6 is obviously of greater capacity than the pump 69 which only operates once for each five revolutions of the organization I2 while pump I6 is driven at the motor speed. The exhaust of pump I6 is connected both to the intake of pump 69 and to the upper end' of container I5 and acts as an agitator keeping the contents of container I5 thoroughly mixed.

Gear 62 carries a pin 11 for coaction with a snap-action switch actuator I8 which cooperates with switch I9. The switch construction I8, I9 forms no part of this invention and is simply a coin-controlled mechanism for providing the double cycle operation necessary in this type of machine.

In operation, rotation of the organization I2 carries with it brush 21 which is passed about thefoot a predetermined number of times, which may be regulated through regulation of the re spective tooth counts of gears I5 and 62 since the switch members I8 and I9 permit one complete revolution of g'ear 62 to complete a shoe shining cycle. The cam II causes oscillation of brush 42 which will pass to and fro over the toe of the shoe, this cam insuring. proper timing of the brush oscillation so that there can be no contact for interference between the two brushes.

Preferably, the measuring pump 69 is set'to operate during the second revolution of brush 21 so that the first revolution is a dusting revolution, the second revolution a polish-applying revolutidn, and the third, fourth and fifth revolutions are utilized for polishing.

It will be noted that the structure is extremely simple for this type of machine, eliminating to a great extent the expensive gearing ordinarily employed. Furthermore, through use of the polish as a lubricant, many difficulties arising from the lubricating problem are eliminated. .The use of the circulation pump insures proper mixture of the materials at all times which is in itself an important item, for the reason that liquid polishing mediums of the type employed in such machines have a distinct tendency to stratify.

Since the construction is obviously capable of considerable modification without in any manner departing from the spirit of the invention, I do not wish to be understood as limiting myself thereto except as hereinafter claimed.
