HARRY CHARLES LOWENSTEIN, OF OAKLAND, MARYLAND.

BOOT AND SHOE POLISHING MACHINE.

Specification of Letters Patent.

Patented Nov. 9, 1909.

Application filed June 13, 1908. Serial No. 438,355.

To all whom it may concern:

Be it known that I, HARRY G. LOWEN s'rniN, of Oakland, in the county of Garrett and State of Maryland, have invented certain new and useful Improvements in Boot and Shoe Polishing Machines; and I hereby declare that the following is a full, clear, and exact description thereof, reference be ing had to the accompanying drawings, which form part of this specification.

This invention is an improvement in shoe polishing-machines, and its object is to provide a machine by which the shoes can be polished while on the feet of the wearer, and

1 which will do the work thoroughly and give a satisfactory shine. Such machines may be located in public places and can be operated while the wearer is seated, and are so constructed that while the work will be eliiciently performed there will be no danger of injury either to the shoes or the wearer.

The machine in brief comprises a set of endless belts arranged to polish the sides, heel and toe of the shoe, and means whereby the said belts are put in operation at the proper time and continue in operation until the polishing is perfected. Means are also provided whereby the shoe rest and side polishing belts can be automatically adjusted to suit different sizes of shoes; and means are provided for applying the proper quantity of blacking to the shoes preparatory to the polishing operation.

An important feature of the invention is the employment of tubular polishing belts and means whereby such belts are supported and guided and at the same time kept properly distended so that they will always be in operative condition.

The invention comprises various novel details of construction, and combinations of parts, all of which will be more fully set forth in the following description, and the parts for which protection is desired are summarized in the claims.

In the accompanying drawings: Figure l is a central longitudinal sectional view of the complete machine. Fig. 2 is a diagrammatical plan view thereof. Fig. 3 is a horizontal sectional view taken on line 3-3, of Fig. 1. Fig. 4 is an enlarged vertical sec tional view in detail showing the shoe and heel platein elevated position and the swinging side belt carrying frames open, in initial position. Fig. 5 is a similar view to Fig.

i with the shoe depressed and the swinging frames closed. Fig. (5 is a sectional plan view of the device for closing the swinging frames. Fig. 7 is aside view of the same partly in section. Fig. 8 is a horizontal sectional view on line 88,of Fig. 5. Fig.9 is a similar view on line of Fig. 5. Fig. 10 is a horizontal section on line 10*l(), of Fig. 5. Fig.11 is a detail side view of one of the shafts carrying the evening and pressure rollers. Fig. 12 is a detail view of the levers for adjusting the heel plate and wedge for diil'ercnt sizes of shoes. Fig. 18 is a detail sectional view of the device for moving (back and forth) the main side belt carrying frame. Fig. 14 is a side view of the same. Fig. 13 is a plan view of the dial-plate for controlling the heetplate and wedge adjusting mechanism. Fig. 16 is a detail sectional view of one of the blackening wells for applying blaclting to the side belts. Fig. 17 is an enlarged view of one of the endless tubular belt distending and supporting frames. Fig. 18 is an enlarged section on line X-X, of Fig. 17. Fig. 19 is an enlarged horizontal section on line YY, Fig. 17. Fig. 20 is an enlarged section on line e2, Fig. 17, indicating how brush surface might be applied to the endless belt. Fig. 21 is a detail side elevation of the endless belt supporting devices. Fig. 22 is a section on line \VW, Fig. 21.

The polishing devices may be arranged within a casing 1 of any suitable construc tion which as shown somewhat resembles an ordinary boot black stand provided with a seat 1 and with a shoe-rest frame 2 in front of the seat, which frame normally stands in the position indicated in dotted lines Fig. 1, pro ecting at that time slightly above the top of the casing. This frame is connected to a pivoted lever A which is pivoted to a bracket 2* attached to the rear of the casing as shown. On the said frame is a sole-rest plate 2* and a heel-rest 2.

The heel support 2 and its rest is movable to or from the sole support and is positioned relatively thereto by means of a rod 2 pivotally connected to the heel support and to an arm 2 on a transverse rock-shaft 6.

Mounted on the frame below .the heel and sole rest is a grating composed of opposite sets of plates 2 connected to rods 2* which are pivoted at their lower ends upon a rod 2", connected to frame 2 as shown in Figs. 1,

4 and 5. When the frame is in elevated position the grating 2 closes the opening in the upper part of the frame as shown in Fig. at and prevents tampering with the mechanism inside the frame; and when the shoe rest is lowered as indicated in Figs. l and 5, the grating collapses as indicated in Fig. 5 beneath the shoe rest, and does not interfere with the mechanism.

The frame 2 and lever 2 are raised to the dotted position shown in Fig. l by the heavy coiled expansive spring 2 Arranged at opposite sides of this shoe-rest frame 2 and just below the top of the casing are endless polishing belts at, a, which are preferably tubular in cross section shown and run over sets of pulleys 4 near the opposite ends of the machine and also over idler pulleys l a number of which are employed as shown in Fig. 3, so that the outer runs of each belt can make several return bends in passing from one pulley at to the other; although the inner runs of the belts a pass directly from one pulley P to the other. In this manner very long belts can be employed.

The belt guide rollers 12" also serve to bring the belts l close together at the toe of the shoe, and prevent the shoe slipping too far forward if it should be carelessly raised off the shoe rest.

The inner run of each belt 4 adjacent the shoe rest 2, is distended by means of frames I and i (see Figs. 1 and 1'? to 22), connected to a support t carrying two rollers which are within the belt and are re tained between pairs of grooved rollers 4:" attached to the bracket suitably supported on the framework exterior to the belt as shown.

The rollers r contact the outer side of the belt and the rollers P are arranged within the belt and by this arrangement of rollers the frame at is supported and kept in proper position within the belt while the belt itself can pass freely between the moving surfaces of the rollers 4, st", although the frame is kept from longitudinal movement within the belt or other movement of the belt. The arrangement, as illustrated in Fig. 17, I have found satisfactory and it practically serves its purpose very efficiently.

To the support 4 within the belt, is attached a belt-diste 11ding frame 41-" which may be conveniently formed of wire, see Fig. 17, and projects at the side of the frame toward the rollers at. While at the opposite side of the frame 4 is attached a belt distending frame 4, which extends toward the rest 2. This distender 4' extends toward the shoerost 2, but not to it. And to this frame 4' is attached a curved wire distender 4 which extends past the rest 2 and preferably formed of a wire, the upper end of which is curved backward as indicated in Fig. 17, the upper end of this wire terminating in rear of the shoe-rest 2. By this means the belt 4- can be distended both in advance and in rear of the shoe and at the same time left perfectly flexible adjacent the shoe-rest so that it can be brought into close contact with the shoe and be easily pressed into contact with the irregular sides thereof, as indicated in Figs. 3, 5 and b.

In order to prolong the life of the belts l, I preferably arrange devices for giving each belt 4 a slight axial rotation upon itself simultaneously with its linear movement; and for this purpose a tube or burwheel -l is rotatably mounted upon a support at attached to bracket 4%, (see Figs. 19 to 22) and contacts with one side of the belt and said wheel is arranged at such an angle that as the belt moves therepast the wheel 4 tends to rotate the belt upon its axis just before-it reaches the spreader. The axial rotation is very slow as compared with the longitudinal travel of the belt, but is suflieient to prevent undue wear on any one portion of the belt, and this materally prolongs the life thereof. To give the wheel f" a grip on the belt the frame 4 may be closed by a sheet l of tin or other suitable material as shown in Figs. 17 and 22.

Each of the belts el and its system of carrying rollers is mounted upon a swingable frame 5, see Figs. 1 to 5, which frames are hinged at bottom on longitudinal shafts 5. Said frames can be swung to and from each other (as indicated in Figs. f and 5) so as to bring the inner run of the belts into contact with the opposite sides of the shoe, or separate them as desired. The rollers 4 are mounted on shaft 4" (see Fig. l) which have bevel gears 46 on their lower ends meshing with bevel gears 5 on shafts 5, which shafts are intergeared by gears 5, (see Fig. 6), and may be driven by bevel gears 5 and 5, from a counter-shaft 5", on which is a pulley 5 driven by a belt 5 from an electric or other motor M, located under the seat, or at any other proper point. The belt 5 as shown runs over suitable guide rollers 5" in the casing.

On each frame 5 adjacent the inner run of the belt 4-, and at points adjacent the shoerest frame 2 are a series of vertically disposed rock-shafts 5' (see Figs. 941) pro vided with spring arms 5 carrying rollers 5* which are adapted to press the inner runs of the belts 4: against the sides of the shoe, when the shoe'rest is lowered to operative position as indicated in Fig. 5.

The frames 5 can be swung to or from each other being loose on shaft 5 by means of crank-arms 5 pivoted onfixed supports 5, see Figs. 4 and 5, and having their outer arms provided with pins or rollers engaging parts of frames 5, while their inner arms are provided with pins or rollers engaging slots 5'", in the upper end of slides 5. The slides 5" are connected to a bar a which can be de- I pressed at the proper time by means of a l cam 7" on a transverse shaft 7, which cam is arranged to hold down the bar during a sufficient part of the revolution of shaft 7 to 1 insure the proper polishing of the sides of the shoe by the belts -l.

The shaft 7 may be driven from the counter-shaft 5" by means of pulleys 7 and I)" and belt i as indicated in Figs. 1 and The weight of the frames 5 will normally tend to cause them to drop apart and raise bar 5 when the cam 7* frees the bar.

The shafts 5 are jonrnaled in bearings 5 attached to a movable frame 5 which is movable longitudinally in the casing as hereinafter explained and which carries the shafts 5 and frames 5 and all the parts supported on said frame, including the belts 4 and their operating devices.

The gear 5" is splined on one of the shafts 5 thus permitting the movement of shafts and frame without moving the gearing 5 out of mesh with gear 5 so that the shafts 5 may be dri\ en in all positions of the frame 5".

The frame [i and the parts carried thereon may be moved at the proper times by the following devices: The shafts 5 may be extern-ally screw-threaded adjacent the shaft 7, as indicated in Figs. 1, 3, l3 and 14. Pivot-ally supported above each shaft 5 is a half-nut 3 mounted on a frame 3, which frames are connected together and pivoted at their angles to a fixed support 1", as shown in Fig. 1, so that when one half-nut is depressed into engagement with the threaded portion of the adjacent shaft .3 the other half-nut is disengaged from its shaft 5. The half-nuts are also provided with arms or fingers 3 which project parallel with the shafts 5 and underlying cams 7 ,7, respectively on shaft 7. These cams are so set that when one cam is in engagement with the adjacent finger 5 the other will be disengaged: so that during one rotation of shaft 7 the first halfaiut will be thrown into engagement with its shaft and then the other half-nut, as indicated in Figs. 13 and 14. As shafts 53 rotate in opposite directions and as the half-nuts 3 have no linear movement it will be obvious that when the nuts are enga ed with the shaft the frame 5" will be compe led to travel forward or backward. The cams 7. 7 are so proportioned and arranged that at. the proper time during the rotation of shaft 7 the frame a" will be moved outward; it will remain outward during the polishing of the sides of the shoe, and at the proper time it will be moved inward and remain inward during the polishing of the toe and heel of the shoe,-and then will be moved outward and remain outward until the next side polishing operation is performed. Obviously the times of move ments and dwells of the frame 5" can be readily controlled by properly proportioning and arranging the cams 7", 7.

On the lower ends of rock-shaft 5' are crank-arms 15 hearing spring-fingers l5 which are adapted to contact with a wedgepiece 15, see Figs. 4, 5 and 10, which is connected by a link 15 to a crank 15' on the rock-shaft (5 to which arm 2" is attached.

The shaft 6 may be rocked by means of a.

hand-lever 6 as indicated in dotted lines Fig. l, and this lever may control the operation of the motor by any suitable mechanism, a catch (i adapted to operate the motor switch in any suitable manner being conventionally indicated in the drawings.

In order to properly position the shoe, a sleeve 6" is placed around lever 6, see Figs. 1, 3, 12 and 15. This sleeve carries a disk 6 which is provided with a series of numerals to indicate the number of the shoe of the occupant of the chair. Said sleeve can be rotated so as to bring any numeral 0 iposite a pointer (3 fixed on the upper part 0 lever 6. On the lower end of this sleeve 6 is an arm 6 which engages the crank-arm 2 see Figs. 1 and 12, and by turning sleeve 6*, arms 2 and 15, which are connected, can be simultaneously shifted so that the frame will move the heel 2 to the proper position on the frame 2, and arm 15 will shift the wedge 15 so as to throw the pressure rollers 5 toward the shoe and bring the belts 4 into proper contact with the sides of the shoe.

Upon the frame 5 is supported a toe-polishing belt 8 which runs over a series of guide rollers 55*, and is preferably made tubular like belt 1, and may be provided with a distending frame 8 as indicated in Fig. 2.

' The belt 8 may be driven from one of the shafts 5 by means of rollers 8 driven by bevel gears 8 8, and counter-shaft 8, as indicated in the drawings. The toe belt 8 is normally retracted out of the way of the shoe in the position shown in full lines in Fig. 1; but after the sides of the shoe are polished the frame 5 is moved rearward and carries the upper portion of the belt 8 over the toe of the shoe, which rises to the position shown in dotted lines, Fig. 1; and the toe is polished as indicated in dotted lines in Fig. 1, and in full lines in Fig. 2.

Arranged beneath the seat 1 is the heel polishing belt 9, which runs over guide rollers 9 mounted in a movable frame 9"; and one run of this belt is pinched between rollers 9, one of which ma be driven by means of bevel gears 9, 9 vrom a countershaft 9 which may be driven by a pulley 9 and belt 9* from the motor, as indicated in Fig. 1.. The frame 9 has depending lugs 9* engaged by the upper ends of levers 9 pivoted at 9", and the lower ends of said levers engage eyes 9 on frame 5", so that as said frame is moved inward, frame 9 is moved outward so as to bring the forward portion of the belt 9 into contact with the heel of the shoe, as indicated in dotted lines in l ig. 1 and in full lines in Fig. 2. When the frame 5 moves outward the frame 9 is moved rearward and out of the way. The movable frame 9 may have guide strips 9' on its front side to direct the heel of the shoe properly against the belt 9.

In order to supply blacking to the shoe, I. provide suitable fountains and means for supplying blacking at intervals to the polishing belts 4, S and 9. The belts 4 may be supplied with blaeking from fountains 1.0, see Fig. 16, each of which contains a rotatable disk 10 supplying blacking to an idler roller 10 which stands normally close to the inner run of the adjacent belt 4. The fountain 10 is mounted on one arm of cranklever 10 the other arm of which underlies a cam 7" on shaft 7, and said cam is arranged to oscillate the lever at the proper moment and momentarily bring roller 10 into con tact with the moving belt 4, and thus supply a small quantity of blacking to the shoe by means of the polishing belt.

Blacking may be supplied to belt 9 by a roller 11 and disk 11 from a fountain 11 similar to fountain 10, and mounted on the one arm of an oscillatin lever 11, the other arm of which is adapte to be engaged by a cam 7* on shaft 7 as shown, which, at the proper moment, will cause the fountain 11 to su ply blacking to belt 9.

'A fbuntain 12 carrying a roller 12* underlies a horizontal portion of the belt 8; fountain 12 being mounted on one arm of a lever 12 the other arm of which is ada )ted to be engaged by a cam 7 on sha t 7, whereby the fountain is caused to supply blacking to the belt 8 at the proper time.

Operation: A person takes his seat upon the machine and after turning the tube 6" until the number of his shoe is opposite the indicator 6", places his foot upon the shoe rest and depresses the same to the position shown in full lines in Fig. l, and by moving the lever 6 starts the motor in operation. Blacking is first sup lied from fountains 10 to the inner sides 0 the belts 4 and thence to the shoe, and simultaneously the belts are pressed into close contact with the sides of the shoe at all points by means of the springpressed rollers 5" indicated in Figs. 8 and 9, and the sides of the shoe are quickly polished. At the completion of this operation frame 5" is moved rearward, bringing the belt 8 over the toe of the shoe and projecting belt 9 toward the heel, and the shoe-rest is raised to the position indicated in dotted lines Fig. 1, the toe catching under the belt 8 which closely embraces it and thoroughly )olishes it, while the heel is olished by the It 9, blacking being initiaily supplied to the belts 8 and 9 priorto the polishing operation. Upon the completion of the heel and toe polishing operations, the frame 5" is moved outward to the position shown in full lines Fig. l, withdrawing bolts 8 and 9 out of the way of the shoe-rest; and upon the completion of the cycle of operations the machine comes to a full stop, until the motor is again released.

Owing to the peculiar nature of the polishing belt the surface presented to the shoe is coi'itinually changing and the operation can therefore be repeated almost indefinitely without liability of the belts becoming clogged or unfit for use. If desired the tubular belts may be faced with brushes or any suitable polishing surface as indicated at l in Fig. 20.

From the foregoing description and the drawings the construction and mode of op eration of the machine will be fully understood.

In practice I )ropose to provide suitable coin-controlled (evices for regulating the operation of the machine, but such devices are not claimed herein, and it is not necessary to disclose same more fully.
