KApplication May 29, 1,956, Serial No. 588,068

i 16 claims. (ci. 15z4) This invention relates to polishing devices and, more particularly, to an improved manually controlled and portable power driven polishing tool of the rotary type.

It is an object of this invention to provide a polishing device of the character described which is particularly devised for polishing shoes and comprises a portable frame whose lower end is provided with an annular rotary polishing brush or pad and an inner axially movable reservoir or housing for containing wax or a paste type of polishing compound with a polish applying brush journaled on the lower portion of said inner housing about an axis substantially transverse to the axis of the polishing brush. Means are provided to shift the inner housing axially of the outer polishing brush so the polish applying brush or applicator element is lretractable and extensible with respect vto the outer polishing brush and wherein means are provided to automatically transmit rotation to the polish applying brush or applicator element onlywhen it is in extended position.

When the applicator element is driven, its bristles or other surface, remote from the surface to which the polishing compound is to be applied, rub against the paste wax orcompound so that some of the compound adheres to the applicator element and is, thus, transferred onto the surface to be polished. Thus, when the inner polishing element or annular brush is retracted relative to the outer polishing element or annular brush, the outer polishing element then polishes the desired surface by a rotary motion without applying additional polishing compound to the surface.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which:

f' xHCC Figure 10 is a view similar to Figure 1, with parts broken away, showing the applicator in retracted position and omitting the electric motor;

Figure l1 is a sectional View similar to Figure 6 showing a modified form of the invention wherein the driving rotary element imparts rotation to the corresponding driven rotary element by means of gears while, in the iirst form of the invention, rotation is imparted to the driven rotary element from the driving rotary element through the medium of friction rollers, and also showing how a flexible shaft may be used for driving the device;

Figure l2 is a fragmentary sectional plan view taken substantially along line 12-12 in Figure 1l.

Referring more specically to the drawings, the iirst form of the invention is shown in Figures 1 through 10 and, for purposes of clarity, it will -be assumed that the polishing tool normally occupies the position shown in Figure 1 although it is apparent that the polishing tool may be used in any desired attitude. The polishing tool comprises a main housing broadly designated at 10 which is shown in the form of a cylindrical shell, but which may be of any desired construction.

The lower portion of the main housing 10 has an annular shoulder or bearing member 11 therein which may be integral with the housing 10 or may be in the form of a ring secured in the housing 10, as by screws 12, Spaced above the annular bearing 11 is a pair of diametrically opposed arcuate or segmental blocks 13, 14 which may also be integral with the housing 10` and are shown as being xed to the housing as by screws 151, 16. The screws 15`also serve to secure a guide block 20 to what may be termed as the rear surface of the shelllike housing 10.

A drum-like axle or outer rotary element 21 is loosely mounted in the housing 10 and is provided with a reduced journal portion 22 which extends through and is journaled inthe annular bearing member 11. The upper end surface of the axle 21 of the iirst form of the invention is smooth and spaced below the level of the blocks 13, 14 for engagement by a driving roller 23, preferably made of rubber or other resilient or friction material. It will be observed in Figures 5, 6 and 7 rthat the lower outer portion ofthebloclr 13 is cut away to form an opening 25 therein to accommodate the friction lroller 23. Also, the external block 20 and the housing .10 are provided with coinciding passageways or openings26 through which the roller`23 loosely extends.v The roller 23 is xed on a shaft 27 which may be a part of an electric motor, such as is indicated at 30 in Figures l, 2 and 3, or which `may be connected to a ilexible shaft driven by a motor or other means remote from the improved polishing apparatus. A shaft of this type is shown in association with the modied or second form of the invention to be later described.

ln this instance, the electric motor 30 is provided with a reduced front end portion 31 which tits in a pressure block 32 guided for vertical movement in the external guide block 20. The pressure block 32 is limited as to vertical movement by a pair of vertically spaced retaining blocks 33, 34 fixed in the external guide block Ztl. Opposed sides of the external guide block 20 are provided with slotsV 35 therein to provide access to a pair of screws 36 which are threaded intoopposite sides of the pressure block 32 and bear against opposite sides of the reduced portion 31 of the electric motor 30 to securel said reduced portion in the pressure block y32.

`rEhe lower retainingblock34 (Figure 5) has ashaft 40 mounted for sliding movement therein parallel to the axis of the housingland whose uppery end,` is suitably s ecuredto the pressure block 32, as by beingthreaded 'thereinto- |lfhe lowerretaining blockS-l has a cavity 41 iii its lower portion through which the shaft 40 extends and in which the upper portion of a compression spring 42 is positioned. The lower end of compression spring 42 bears against an abutment 43 on the lower end of the shaft 40, which abutment is shown in the form of a Washer supported on the lower end of the shaft 40 by means of a lock nut 44.

It is thus seen that the pressure block 32 is normally urged downwardly so the motor 30, shaft 27 and roller 23 are urged downwardly therewith relative to the housing and thereby insures that the roller 23 is maintained in pressure engagement with the mating or upper end surface of the axle 21. It is thus seen that, when the motor is energized, the roller 23 transmits rotation to the axle 21.

The lower end of the reduced portion 22 of the axle 21 has an annular outer polishing element support ring 46 mounted thereon preferably by means of a plurality of circularly spaced radially and inwardly projecting pins 47 which iit in corresponding bayonet slots 50 provided in the lower end of the reduced portion 22 of the axle 21. The element 46 may also be termed as an outer annular brush holder. This brush holder is preferably channelshaped in cross-section and in this instance the metal encased upper end of an annular brush 52 is xed in the brush holder 46 by means of the pins 47. It is to be distinctly understood that a pad or other annular resilient polishing element may be substituted for the brush 52, without departing from the spirit of the invention.

Mounted for axial movement within the main housing 10 is an elongated tubular secondary or inner housing broadly designated at 55. The upper portion of the inner housing 55 is loosely mounted for movement between the proximal surfaces of the inner guide blocks 13, 14 and these guide blocks have the upper portions of respective keys or guide rods 56, 57 suitably secured thereto, which guide rods extend downwardly and terminate within and adjacent the lower end of the reduced` portion 22 of the axle 21. The inner tubular housing 55 is guided for axial or vertical sliding movement on the keys 56, 57 as best shown in Figures 7 and 8.

The inner or secondary housing 55 has a longitudinally extending, eccentric and internally threaded bore 60 therethrough within which a tubular polishing compound cartridge holder or reservoir 61 is loosely mounted. It should be noted that the tubular reservoir 61 is not externally threaded. Instead, a polishing stick cap 62 is mounted for axial sliding movement in the polishing stick holder 61 and has a key or pin 63 projecting radially and outwardly therefrom through a longitudinally extending slot 64 provided in one side of the polishing stick holder 6l (Figures 7, 8 and 9). The outer end of the pin or key 63 engages the threads in the threaded bore 60 of the inner housing 55, for purposes to be later described.

The cap 62 is preferably of inverted cup-shaped construction and is provided with a key 66 therein for attaching the upper end of a polishing stick 67 to the cap 62. The polishing stick 67 may be madefrom wax or any other desired pliable polishing material and is of such diameter to move freely and axially within the polishing stick holder 61.

The tubular polishing stick holder 61 projects above the level of the blocks 13, 14 and has an enlarged head member 70 integral therewith or attached thereto and provided with an annular groove 71 in its periphery which is engaged by the free end of a latch 72. The latch 72 is fixed on the upper end of a relatively small rod or shaft 73 (Figures 6, 7, 8 and l0) whose lower end is journaled in the inner housing 55 and extends through a groove or notch 74 formed in the periphery of the upper portion of the housing 55. A collar 75 is fixed on a medial portion of the shaft 73 or formed integral therewith and is positionedin the notch 74. The lower end of the collar 75 is provided with a notch 76 for'accomrnodating a torsion spring 77 (Figure 10) encircling the shaft 73.

One end of the torsion spring engages the shoulder formed by the notch 76 in the collar 75 and the other end of the torsion spring 77 engages the inner wall of the notch or groove 74 to thereby normally urge the latch into operative position as shown in Figure 8. It will be noted that latch 72 is held on the upper end of the shaft or rod 73 by means of a pin 80 (Figure 8) which serves as a hand lever for swinging the latch 72 out of engagement with the groove 71 in the cap 70 of the polishing stick holder 61 so the polishing stick holder may be readily removed from the inner housing 55, when desired.

It will be noted in Figures 6, 7, 9 and 10 that the outer surface of the inner housing 5S is also provided with a pair of adjacent recesses 81, 82. The shaft 73 also extends through the recess 81 and has a sleeve 83 loosely mounted thereon and loosely positioned in the recess 81. The inner surface of the sleeve 83 is attened, as at 84 (Figure 7) to prevent inadvertent rotation of the sleeve 83. The sleeve 83 has a radially projecting pivot pin 85 tixed thereto which ts in the bifurcated forward end of an operating lever 86 (Figure l0).

The operating lever 86 curves rearwardly inwardly of the wall of the housing 10 and then extends outwardly through an opening 87 formed in the cylindrical shell of the housing 10. The operating lever 86 is pivoted, as at 90, adjacent its rear or outer end, on a plate 91 suitably secured to one side of the external guide block 20. The plate 91 could be omitted, but it is provided to cover the recess in which the head of the corresponding screw 1S is disposed.

The upper portion of the operating lever 86 may extend rearwardly and terminate adjacent the motor 30 so as to be manually operated, if desired. However, for convenience, the upper portion of the external guide block 20 has a projection 92 on one side thereof in which a pair of push buttons 93, 94 is mounted for vertical sliding movement. The lower ends of the push buttons 93, 94 are pivotally connected, as at 9S, 96 to the operating lever 86 rearwardly and forwardly of the pivot 90, respectively.

It isthus seen that, when the inner housing 55 is in raised position relative to the outer housing 10 as shown in Figure 10, the forward push button 94 may be depressed to lower the housing 5S to substantially the position shown in Figures 1, 5 and 6, for example. On the other hand, when the rear push button 93 is depressed, the inner housing 5S is retracted from the position shown in Figures l, 5, 6, 9 and ll to the position shown in Figure l0. In order to assist in maintaining the inner housing S5 in the position to which it is moved by either of the push buttons 93, 94, a retaining latch 97 is pivotally connected to the operating lever 86 (Figures 1 and l0) adjacent the pivot 96 of the push button 94. This latch 97 extends downwardly and rearwardly at an angle and has a pair of closely spaced recesses or notches a, b in its rear edge which are adapted to alternately engage a retaining pin c projecting outwardly from the plate 91.

A leaf spring member or torsion spring d is mounted on a pin e projecting from the plate 91 and bears against the lower forward surface of the retaining latch 97 to thereby urge the retaining latch 97 into engagement with the retaining pin c. When the inner housing 55 is in the retracted position shown in Figure 10, the notch a engages the retaining pin c and, when the inner housing 55 is in extended position relative to the outer housing 10, the notch b in the retaining latch 97 engages the retaining pm c.

As heretofore stated, the threaded bore 60 in the inner housing 55 is eccentric relative to the axis of the inner and outer housings 55, 10 and it' will be observed in Figures 1, 3, 4, 6 and 9 that the inner Ihousing 55 is provided with a pair of downwardly projecting ears or iins 100, 101 which are substantially alined with substantially diametrically opposed inner surfaces of the threaded bore 60 and between which a rotary inner polishing element or applicator 102 is mounted for rotation about a substantially horizontal axis, or, in other words, about assaess an axis transverse to the axis of the outer rotary polish ing element 52.

In this instance, the inner rotary polishing element 102 is shown in the form of a brush whose bristles rub against the lower end of the polishing stick 67 disposed in the polishing stick holder 61, as best shown in Figures 5 and 9. As best shown in Figure 4, the core of the brush 102 is fixed on a shaft 104, one end of which is journaled in a bushing 105 threaded through the ear 100 extending downwardly from the inner housing 55. It will be noted that the lower end of the ear 100 has a slot 106 therein (Figure 5) which communicates with the threaded bore 60 through which the bearing or bushing 105 extends and which is of sufficient width to permit the shaft 104 to pass therethrough.

The end of the core of the brush 102 opposite from the bushing 105 has a hub portion 107 projecting therefrom (Figure 4) and the outer end of a lateral key portion f on the right-hand end of the shaft 104 in Figure 4 terminates substantially flush with the outer surface of the hub 107. The ear or iin 101 projecting downwardly from the lower end of the inner housing 55 has a stub shaft 110 journaled therein which stub shaft is also journaled in an auxiliary fin or ear 111 which also depends from the inner housing 55 and is spaced outwardly of the fin or ear 101. The inner end of the shaft 110 is slotted to engage the key f on the corresponding end of the shaft 104 and it will be noted that the inner end of the stub shaft 110 then fits in the hub 107.

It is thus seen that, by removing the bushing 105 from the iin 100 in Figure 4, the brush 102 with its shaft 104 may be moved to the left to disengage the key f from the corresponding end of the stub shaft 110 and to thereby facilitate ready removal of the brush 102 from between the fins 100, 101 of the inner housing 55 for purposes of cleaning or replacement, if desired.

Now, in order to drive the lateral brush 102, the shaft 110 has a relatively small worm gear 112 fixed thereon which engages a worm 113 (Figures l, 3, 6 and 9) mounted on the lower end of a shaft 114 which extends parallel to the axis of the outer and inner housings 10, 55. The shaft 114 is journaled in the wall of the inner housing 55 and extends through the recess 82, the latter recess being of substantially greater length axially of the inner housing 55 than the recess 83. Disposed within the recess S2, of the housing 55 is a resilient or pliable roller 115 which is fixed to or molded onto a bushing 116, mounted for axial sliding movement on the shaft 114.

rllhe shaft 114 is slotted longitudinally thereof, as at 117 (Figures 6 and 7), and a pin 120 (Figure 9) loosely extends through the slot 117 and is fixed in the bushing 116 and the roller 115. Thus, the roller 115 is keyed for axial movement on the shaft 114, but cannot rotate relative to the shaft 114. The upper end of rolle-r 115 is engaged by the lower end of a co-mpression spring 122 whose upper end bears against the upper wall of the recess 82 as best shown in Figure 9. The shaft 114 has a collar 123 adjustably secured thereon for engaging the bottom wall of the recess 82 to thereby prevent endwise movement of the shaft 114 relative to the inner housing 55.

The lower portion, at least, of the roller 115 is preferably tapered as shown in Figure 9 and, when the inner housing 55 is moved to extended position from, say, the position shown in Figure l0 to that shown in Figures 5, 6 and 9, the roller 115 engages a tapered inner surface 124 on the tubular axle 21. Since the tubular axle 21 is constantly driven in the manner heretofore described, it is apparent that, when the roller 115 is moved downwardly into engagement with the tapered surface 124 of the axle 21, and biased thereagainst by the compres sion spring 122, rotation is then imparted to the shaft 114, which, in turn, drives the lateral brush 102 through the medium of the worm 113, worm gear `112, shaft 0 and the shaft 104 of the inner rotary polishing element 102.

Itis thus seen that means are provided to automatically impart rotation to the secondary or polish applying brush 102 whenever it is in extended position relative to the outer rotary element or brush 52 and to also automatically cause rotation of the inner polishing element or applicator 102 to cease when it is in retracted position relative to the outer rotary polishing element 52.

Since the inner brush 102 rubs against the lower end of the polish stick 67 during rotation thereof, it is apparent that the inner brush 102 transmits polish from the polish stick 67 to the surface to be polished. On the other hand, when the inner brush 102 is retracted, since the outer brush 52 rotates continuously, it is apparent that the surface to be polished may then be polished without additional polishing compound being applied thereto. i

Now, the polish stick 67 may actually be of greater length than that shown in Figure 5 when it is initially inserted in the polish stick holder 61. On the other hand, as the polish stick is used, it is apparent that it becomes worn and it is necessary to extend the same relative to the polish stick holder 61. However, it is necessary, in order to move the polish stick 67 in either direction, for the operator to grasp the head 70 of the polish stick holder 61 to thereby rotate both the head 70 and the polish stick holder. In so doing, the pin 63 causes the polish stick cap 62 and polish stick 67 to rotate with the polish stick holder 61 and it is apparent that the pin 63 follows the threads in the threaded bore 60 so that, with rotation of the polish stick holder 61 in one direction, the polish stick 67 and cap 62 are moved axially in one direction and, conversely, with rotation of the polish stick holder 61 in the other direction, the polish stick 67 and the cap 62 move axially in the other direction.

It might be stated that, in order to remove the polish stick holder 61 from the housing 55, it is necessary to rotate the same until the pin 63 has moved the polish stick 67 and the cap 62 to where the pin 63 is disposed above or has ridden out of engagement with the threads in the threaded bore 60. The upper end of the main housing 10 is partially closed by a dome-like closure cap 130 whose upper end is preferably provided with an opening 131 therein so that the operator may View the position of the polish stick cap 62 therethrough Without removing the cover or closure cap 130.

The polish stick holder 61 may also be rotated by inserting ones fingers through the opening 131. The lower end of the closure cap preferably fits within the cylindrical shell forming the main housing 10 and is provided with bayonet slots 132 for engaging pins 133 projecting inwardly from the main housing 10 to thereby facilitate easy removal of and replacement of the closure cap 130, when desired.

Referring now to the form of the invention shown in Figures ll and 12, most of the parts shown in Figures l1 and 12 may be identical to or substantially the same as corresponding parts shown in Figures l through l0 and, accordingly, the same reference characters will apply in order to avoid repetitive description. In the form of the invention shown in Figures ll and l2. instead of an electric motor being used as the motive means for the polishing tool, an adapter lits in the pressure block 32 and is secured therein in the same manner as the reduced portion 31 of the electric motor 30 is secured in the pressure block 32 in the first form of the invention.

The adapter 140 has the housing 141 of a flexible shaft 142 connected thereto, the other end of the housing 141 and exible shaft 142 being connected to a suitable motor or other driving means remote from the improved polishing tool. The inner end of the iiexible shaft 142A has a bevel gear 144 fixed thereon which is used in the form of the invention shown in Figures l1 and l2 in place of the resilient roller 23 used in the first form of the invention. Accordingly, the upper end surface of the axle 21 in Figures 1l and 12 is provided with gear teeth 145 which are engaged by the bevel gear 144 so that rotation is imparted to the axle 21 in Figures l1 and 12 through the medium of gears rather than by frictional contact between the driving and the driven elements as shown in Figures and 7.

It will also be noted that, whereas in the original or first form of the invention, the resilient roller 115 is used for transmitting rotation from the axle 21 to the vertical shaft 114, in the modified form of polishing tool (Figures 11 and 12) a bevel gear 150 is substituted for the resilient roller 115 and the upper portion of the axle is provided with an inner tapered surface formed with gear teeth 151 which are adapted to be engaged by the gear 150 when the inner polishing element or lateral brush 102 is in extended position. In all other respects, the form of polishing tool in Figures ll and 12 is identical to the form of polishing tool shown in Figures 1 through and a further detailed description thereof is thus deemed unnecessary.

It is thus seen that I have provided a novel polishing tool particularly adapted for use with a plastic or semiuid type of polishing compound with means for continuously rotating the outer annular brush or polishing element 52 and means for extending and retracting the inner polishing element or applicator 102 relative to the outer polishing element or brush 52 and wherein the inner polishing element is driven to rotate about an axis transverse to the axis of the outer polishing element or brush 52.

In the drawings and specification there have been set forth preferred embodiments of the invention and, although speciic terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being deiined in the claims.
