Application led ITanuary 7, 1920. Serial No. 349,904;
To all fw izo/m t may concern:
Be it known that l, HULDRnroH A. Bonn- MAN, a citizen of the United States, residing at Milwaukee, county of Milwaukee, vand State of lWisConsin, have invented new and useful Improvements in Power-Driven Shoe- Shine Brushes, of whichthe following is a specification.
This invention relates to motor driven shoe shine brushes. i
lt has been found that when Va rotary brush is used to polish shoes that the proper shine cannot be secured by rotating the brush in one direction only and thereby brushing the shoes in one direction. It is, therefore, an object of this invention to provide a rotary shoe shine brush having means whereby the alternate 'brushing of the shoes in opposite directions is secured.
A further object is to provide a small, light weight power driven shoe shine brush with the parts so arranged that this alternate brushing may be secured by a relatively small movement of the device.
` ln the drawings-- Figure 1 is a partial sectional view of one form of this device.
Fig. 2 is an end view of Fig. 1.
Fig. 3 is a view similar to Fig. 1 of another form of this device.
Fig. 4 is a transverse sectional view of a further form of this device.
Fig. 5 is an end view of the structure shown in Fig. l with parts broken away to illustrate the arrangement.
Fig. 1 shows a casing 1 within which is housed a pair of juxtaposed axially alined brushes 2 and 3. A handle 1 is secured to the casing 1 and a flexible shaft 5 passes through such handle. This shaft, of course, may be an outer casing and an inner flexible shaft proper if so desired. The `flexible shaft 5 is fastened to a shaft 6 which is pivotally mounted in bearings 7 formed in the casing 1. This shaft extends through the hubs 8 and 9 of both of the brushes, but is keyed only to the hub 8, the hub 9 turning freely upon such shaft. It is understood, of course, that these hubs may be of wood, metal lined if desired. The hubs 8 and 9 have pulleys 10 and 11 respectively secured thereto. From these pulleys belts 12 and 13 extend to similar pulleys 14 and 15 rigidly mounted upon a jack shaft 16 arranged in the upper part of the casing 1.
When the brushes are driven by .a motor u attached to the other end of the` flexible shaft 5, the brush 2 is driven directly from the shaft 6, the pulley 1() rotating therewith. This pulley, through the medium of the belt 12, the cross belt 13 and the pulleys14, 15 and 11, transmits motion'to the brush `3 `and causes such brush to rotate in the opposite direction to the brush 2. v
Fig. 3 shows a second form of the device in which the jack shaftl is replaced by a driving shaft 17 and in which Vthe handle through which said shaft 17 passes is located adj acent the upper portion of the casing. A second stationary shaft 18 is mounted` adjacent the lower portion `of the casing and carries thereonthe hubs 19 and 20 of two brushes 2O and 21 respectively. Pulleys 22 and 23 rigidly fastened to the shaft 17 transmit rotary motion to the brushes 20 and 21 through the medium of pulleys 24 and 25 secured respectively to the hubs of such brushes, the respective pairs of pulleys being connected by a belt 26 and a cross belt 27.
Fig. 4: shows a further form of the invention in which the driving shaft 28 passes through the handle and through the lower portion of the casing. A brush 29 has its hub 30 secured rigidly to the shaft 28 while a second brush 31 has its hub 32 loosely mounted upon such shaft 28. A spring 33 tends to press these hubs together such spring pressing at one end against the outer side of the casing and at the other end against a washer 34, or if desired, a ball bearing, bearing upon the hub 32. In the two forms previously described, a spacer was provided between the hubs of the brushes, but in this form a pair of rollers 35 serve to space the hubs of the brushes. These rollers run in grooves 36 formed in the hubs of the brushes and are carried upon a transverse shaft 37 which is anchored at 38 in opposite sides of the casing and is bowed upwardly at its central portion 39 to avoid contact with the shaft 28. It will be seen that when the dirush 29 is rotated in one direction, the brush 31 is caused to rotate in the Yopposite direction through the medium of the rollers 35.
It will thus be seen that a simple, light weight shoe shine brush has been provided in which a pair of rotary brushes are posil tioned closely adjacent each other and are axially alined so that by relatively small posed brushes;
lshoe is subjected to alternate movement of the device back and forth the brushings in opposite directions.
claiml. A portable device vfor shining 'shoes comprising a pair of axially alined, juxta-V means for simultaneously` causing said brushes to rotate in opposite directions; and manual means for positioning said brushes upon the shoe, whereby shoes may be polished without them .from the feet of the wearer.
2. A device for shining shoes comprising acasing, a handle mounted upon said casing whereby said casing ma be manually manipulated, a shaft exten ing transversely of said casing, la pair of juxtaposed brushes loosely Vmounted upon Vsaid shaft and projecting outwardly froml said casing, and
driving means for simultaneously rotating said brushes in opposite directions.V
3..A device for shining shoes comprising a substantially semi-circular casing having l Van open portion, a manipulating handle supporting .said casing, a shaft extending transversely across said casing, adjacent said open portion, a pau-'of juxtaposed alined removing Y brushes loosely mounted Vupon said shaft, a drive shaft passing through said handle and into the said casing, and means for operatively connecting said drive shaft and said brushes, whereby said brushes are caused to rotate in opposite directions upon rotation of said drive shaft.
'4. A shoe shine device comprising a casing having an open portion, a manipulating handle supporting said casing, Vadrive shaft extending through said handle and into said asing, a pair of pulleys mounted upon said Y rive
