BUBBING MACHINE.

Application 1ed March 27, 1925. Serial No. 18,807.

This invention relates to improvements in rubbing machines, particularly adapted though not necessarily limited. in its use for rubbing, varnished and polished surfaces, and one of the objects of the invention is to `provide an improved machine of this character in which is embodied a rotatable rubbing element adapted to effectively rub curved, irregular, and uneven surfaces, the rubbing element .being rotatable and provided with a spiral shaped work engaging faces or surfaces, adapting thesame for contactv with surfaces which are ordinarily diflicult to reach.

A further object is to provide an improved portable power driven hand device of this character which will be comparatively light to handl'e and in' which there is embodied a plurality of spirally arranged rotatable rubbing facesl operating in opposition to each other. j A further object isvto provide an'improved machine of this character which will be of a' simple, durable and compact construction, and effective and eilicient in operation.

To the attainment of these ends and the accomplishment of other `new and useful objects as will appear, the invention consists in the features of novelt in substan- 'tially the construction, com ination and arrangement of the several parts hereinafter more fully described and claimed and shown vin the accompanying drawing illustratingV this invention, and in which Figure 1 is a view partly in elevation and partly in longitudinal section ofj a machine of this character constructed in accordance with the principles of this invention.

Figure 3 is a vertical, sectional view taken on line 3-3,.Figure 1.

Figure 4 is an elevation of one of the rotatable members for supporting the rubbing elements, andwith the rubbing strips in osition.

igure 5 is a detail view of the member for supporting the rubbing elements. b Figure 6 is a view of one of the filler memers.

Figure 7 is a diagrammatic bottom plan view of the rubbing elements.

In the resent exempliication of this invention the numeral 10 designates a supporting structure which may be of any desired size and configuration and may be provided with a handle 11, by means of which the device may be mampulated. A portion 12 of the structure constitutes a shield which is adapted to extend over the rotatable rubbing elements.

JInthe present exemplication of this invention two rubbingrollers are shown, but it is tov be understood that any number of these rollers Amay be provided according to the size of the device which it is desired toA produce.

Each of the rubbing rollers are preferabl of sectional constructlon, that isto say eac i of these rollers preferably embody two sections 13, each section comprisin a body portion, which is preferably cylin rical and of any desired diameter and length. Around the periphery of each of the sections is provided a series of spirally arranged grooves 14 of any suitable depth and these grooves run throughout substantially the length of the respective sections.

The rubbing elements 15 are constructed of a flexible textile fabric and is formed in strips. These strips are comparatively wide with relation to their thickness and are secured to the respective sections of the rollers by one edge by placing one edge of the eleand co-operating with the adjacent wall of Figure 2 is a vertical, sectional view taken lfiller members 16 are placed in position, a

collar 19 which encompasses the end of the roller, is adapted to engage the adjacent ends ofthe filler members 16 and the collar co operates with the collar or shoulder 18 to clamp and hold the filler members 16 against displacement.

' provided with screw threads 2O on its extremity to receive another collar 2l for holding the parts in position.

The outer extremity of each of the rollers is free and the threaded extremity 20 `of each roller preferably projects for a considerable distance beyond the collar 2l so that additional rubbing elements 22 may be secured to the .end of the roller by means of another collar or nut 23, so that the end of the roller may be utilized for rubbing.` The rubbing elements 22 maybe of any desired configuration and are secured by one edge to the roller, the free edge of the elements 22 being preferably deflected overthe collar 23 andI the end of the roller section in any suitable manner, such as by means of a1 member 24, preferably in the form of a washer. y

The outer edges of the strips 15 are free so that'when the rollers are rotated, the free edges of the elements 15 will be deflected so that their side surfaccswill be presented to the work and will cause a wiping action of the strips upon the surface' when pressure is exerted upon the implement through the medium of the handle 11.

The rollers thus formed embodying the sections 13 and strips 15 with the associated parts are arranged end to end are secured to a shaft 25 for rotation therewith in any desired or suitable manner, preferably by being keyed thereto as at 26. The end of the shaft 25v is preferably threaded as at 27 and passes through a wall or rib 28 in one of the sections 13. A nut 29 is threaded on the end of the shaft 25 and engages the wall or rib 28 and holds the sections 13 against displacement. A collar or shoulder 30 is provided on the sha'ft 25 against which-one end of one of the sections 13 abuts and cooperates with the nut or collar 29 for holding the parts against displacement.

rlhe shaft 25 is rotatably supported in any suitable manner preferably by means of a ball bearing element 3l which is threaded into a recess 32 in the supporting body 10 of the implement. A thrust bearing 33 may be provided for receiving and supporting the end of the shaft. -lVithin the chamber o r recess 32 is arranged augea'r 34, which is secilired to the shaft 25 for rotation therewit i.

Two rollers thus formed may be provided in each machine and are arranged so that they will be parallel to each other and are adapted to be rotatedin opposite directions by means of a gear 35 which meshes with the gears 34. The gear 35 receives its motion from any suitable source of driving power (not shown) and which power is communicated to the gear 35 through the medium of a1 shaft 36. This shaft 36 preferably passes through a portion of the handle so as to be out of the way of the operator.

'Ihe rubbing strips 15 whichare' arranged aboutI the roller sections 13 and which are secured to each of lthe shafts 25 are so' a'rranged that the will run 1n opposition to each other that is so that durinfr'the operation of the device the tendency of the flexible rubbing strips 1 5 is to feed the rubbing material toward the longitudinal centers of the shafts 25, thereby preventing the material from .being thrown outwardly andaway from the work by the operation ofthe .rub-

bing elements. Y

The shield 12 also prevents thezmatcrial from being thrown out by the rubbing elements. I

lVith this vimproved construction it will be manifest that the device is of a simple construction and can be easily manipulated and will be adapted for use on even or uneven and irregular surfaces. Furthermore, the rubbing elements being flexible and'being arranged as shown, will render it possible to reach corners and all portions of curved surfaces. l

While the preferred form of the invention has been herein shown and described it is to be understood that Avarious changes may be' made in the details of construction and in the combination and arrangement of the several parts, within the scope of the claims, without departing from the spirit of this invention.
