Application filed December 16, 1925. fs erial No. 75,752.
This invention relates to improvements in rubbing machine for rubbing polished and varnished surfaces and also the surfaces of automobiles, and one of the objects of the invention is to simplify the construction of such a rubbing machine and thereby materially reduce the cost of manufacture and at the like formed to produce spaced spirally arranged surfaces extending in general directions lengthwise of the rubbing element,
being originally produced preferably as a solid cylindrical mass of material, the rubbing surfaces being then produced by cutting or forming grooves opening through the periphery of the element and extending spirally thereabout and in directions lengthwise of the element.
A further object is to provide improved means for securing the rubbing element to the driving shaft.
To the attainment of these ends and the accomplishment of other new and useful objects the invention consists in the features of novelty in substantially the construction,
' combination and arrangement of the several parts hereinafter more fully described and claimed and as shOWn in the accompanying drawing, in which Figure 1 is a view in side elevation of a device of this character constructed in accordance with the principles of this invention.
Figure 2 is a sectional View taken on line 2--2, Figure 1.
Figure 3 is an isometric view of one of the rubbing elements before the spirally arranged rubbing surfaces are formed.
Figure 4 is'a detail horizontal sectional view as taken on line 4 4,.Figure 2.
Figure 5 is a detail perspective view of one of'the fastening elements for securing the rubbing member or element to its driv- 60 ing shaft.
Figure 6 is a side elevationof one of the rubbing members.
Referring more particularly to the drawipg the numeral 10 designates generally a supporting structure which may be of any desired size and configuration andmounted thereupon is a motor or drivin mechanism 11, a portion 12 of the structure being shaped to form a shield and a handle 13 is also provided by means of which the device may be manipulated and transported.
J ournaled in suitable bearings 14: and disposed beneath the shield 12 are a pair of shafts 15 which are preferably substantially parallel and tubular and these shafts are driven through the medium of suitable driving mechanism (not shown) so that they will rotate in opposition to eac other.
Mounted upon and secure to each of the shafts 15 is a rubbing member, and as the construction of each of these members and the method of. securing them to their respective shafts is the same, the description of one will apply equally as well-to both.
Each of the rubbing members is preferably of sectional construction, here shown as embodying two sections or elements 15 although it is to be understood any desired number of sections may be employed according to the size of the machine and the length 3f rubbing members that it is desired to prouce.
Each of the elements 15 is originally preferably produced as a solid or homogeneous mass of flexible rubbing material such as felt or the like and is provided with an opening 16 of any desired diameter extending longitudinally therethrough and through the ends thereof.
The periphery of the element 15 is shaped in any suitable manner to form spirally arranged and spaced substantially parallel rubbing portions 17 which are integral with the element and extend in general directions lengthwise of the element and form continuous work enga ing portions, the spirals on one section of t e element being arranged in opposite direction to the spirals on the adj acent section. The work engaging portions are preferably formed by cutting away the material formin the element, for any de sired depth, to form the spirally arranged grooves 18 between the surfaces 17 and the grooves are of a de th to allow a substantial amount of the ody of the element to forma hub '19 at the center thereof and through which hub portion the opening 16 passes.
The shaft 15 is preferably tubular and is of a length substantially equal to the combined length of two of the elements 15 ar-' as follows.
An annular member or washer 23 is provided with an inwardly projecting lug 24 and laterally projecting pins 25 which are preferably polnted, any number of. which pins may be provided and they may be of any suitable length, but are of a length to penetrate the adjacent end of the element 15 for a considerable distance. The member 23 is first sleeved upon'the shaft 15 until it abuts the nut or collar 22 and with the projection 24 entering the groove 20 in the shaft.
One of the elements 15 is then sleeved upon the shaft and the pins 25 forced into the end of the element until the element abuts the member 23.
A similar annular element 26 is next sleeved upon the shaft and is provided with a projection 27 which enters the groove 20 in the shaft. The element 26 is provided with laterally projectin impalement pins 28 on one side thereof adapted to enter the other end of the element 15 until the member 27 abuts the end of the element. Another element 15 is sleeved upon the shaft so that the pins 29 will impale the end of the element and said end will then abut the member 27.
An annular member 30 having im alement pins 31 projecting from one face t ereof is then sleeved upon the shaft 15 so that the pins will impale the adjacent end of the element 15, the member 30 may also be provided with a projection 32 adapted to enter the j v groove 20 in the shaft 15.
With this improved construction it will be manifest that the elements 15 will be secured to the shaft 15 for. rotation therewith.
Obviously the elements 15 and the members 23-27 and 30 may be secured together before being-placed upon the shaft 15 andthey may then be placed upon the shaft as a unit instead of being built up upon the shaft. The member 30 is preferably provided with a laterally projecting collar or hub portion 33 which extends beyond thead'acent extremity of the shaft 15 to e engaged y the head 34 of a screw 35 that is threaded into the end of the shaft 15. I
The screw 35 serves as a means for forcing the arts of the rubbing member together and or maintaining them againstlongitudinal displacement upon the shaft. By removing the screw 35 the entire rubbing member may be readily removed from the shaft.
A disclike rubbing element 36 of suitable rubbing material such as felt or the like is provided with a central aperture to receive the hub like portion 33 of the member 30 and the head 34 of "the screw 35 contacts with the face of the element 36 and secures the same to the end of the shaft 15. This element 36 is of a diameter substantially equal to the diameter of the rubbing members and is provided for the purpose of rubbing surfaces or corners which it is impossible to reach with the body of the rubbing member. 5
To the free end of the other of the shafts 15. is secured in any suitable manner a conically shaped or pointed rubbing element 37 and is constructed of any suitable material and is provided for the same purpose as the element 36.
The elements 15 of each of the rubbing members on each of the shafts 15 are arranged 7 so that the spirally arranged rubbing surfaces 17 and grooves 18 will extend about the respective rubbing members in opposite directions with respect to each other and the spirally arranged rubbing surfaces 17 and grooves 18 of the respective adjacent rubbing elements of the rubbing member will be also arranged to extend about the respective members in opposite directions with respect to each other.
With this arrangement it will be manifest that the'rubbing or polishing composition or material that is placed upon the surface to be polished will not only be fed in a direction from the ends of the rubbing members towards the longitudinal center of the respective members, but as the rubbing members rotate in opposition to each other the spirally arranged grooves and rubbing surfaceswill feed the rubbing compound towards the center of the machine.
The spirally arranged surfaces 17 will clean an uninterrupted or continuoussurface to be presented to the work with the result that the formation of streaks or ridges on the polished surface will be obviated.
y the provision of the rubbing element 36 on the end of one of the shafts 15 and the rubbing element 37 on the end of the other shaft 15, for rubbing in corners and between parts that cannot be'reached by the main rubbing elements, there is provided a use.
, eter of the rubbing members.
The shield 12 will prevent the rubbing material from being thrown away from the machine or upon the operator.
