This invention relates to the class of power driven polishers and buffers, and has especial reference to devices of the character which are used for polishing, cleaning, or bufling the 5 smooth or glazed surfaces of automobile bodies, furniture, marble, etc.

The principal object of the present invention is to provide a polisher or buffer of the indicated character which embodies novel features of construction whereby the polisher or buffer may be used to subject the Work with sufficient pressure for setting ,up the polishing or bufiing action without scorching, marring or burning thesurfaces of the work sub jected to the buffing action.

Another and more specific object of the invention is to provide a polisher or buffer which embodies means in the form of a cushion which absorbs excessive thrust pressure while the polisher or buffer is in use.

The nature of the invention and its dis-. tinguishing features and advantages will appear when the following specification is read a in connection with the accompanying draw- 5 ing, in which Figure 1 is a perspective view of a olisher or bufi'er embodying the features of t e pres:

' ent invention. I

Fig. 2 is a sectional view taken on the line 30 22 of Fig. 1.

Generally stated, the polisher or buffer of the present invention comprises a polishing or bufling element 10, a spindle 11 adapted to be connected with a power driven. flexible shaft, and cushioning means 12 connected between the polishing or bufiing element 10 and the spindle 11. J

The polishing or bufiing element 10 is in the form of a disk of felt or like material,-

and consists of two parts, a part 13 and a part 14. These parts 13 and 14 are similar in shape and size. The part 13 is brought into Contact with the work to' be polished, cleaned, or buffed. The spindle 11, as stated, is adapted to be connected with. a power driven flexible shaft, and to this end the spindle isprovided with. a threaded socket 15 into which the terminal of the flexible shaft is threaded.

The spindle 11 also includes a threaded stud .ment.11 in a manner presently to be described. A cup shaped element 19 of resilient '60 material such as rubber is employed. The element 19 has a central opening 20, and an outwardly directed circumferential flange 21. The'e1ement 19' is connected with the spindle 11, and this is accomplished by the 05 use of annular metallic plates or' members 22 r and 23 which surround the stud 16 of the spindle and are arranged respectively on op posite sides of the central portion of the element 19, there being a fiber annular member 24 arranged between the plate 23 and the cen-.

tral portion of the element 19. The stud 16 extendsthrough the opening 20in the central portion of the element 19 as well as through the

lates

22 and 23, and the member 24. The stu 16 being so disposed allows the arrangement of the washer 17 on the stud in contact with the plate 23, and the nut 18 to be screwed on to the stud 16 to effectively clamp all of the parts securely together, to the end that 80, the spindle 11 will be eifectively'connected with the cushioning element 19. The element 19 will be cemented to the plate 22 and fiber member 24. The spindle 11 will thus be prevented from turning with respect to the cushioning element 19.

In order to connect the cushioning element 19 with the olishing or bufiing element 10, I the part 14 oi theelement 10 has cemented or pasted to one face of the central portion 9 I thereof, an annular fiber member 25. The oppositeface of the part 14 has cemented or pasted thereto an annular fiber member 26. An annular member 27 of felt or like material is cemented or pasted to the annular fiber member 25, and an annular fiber member 28 is cemented or pasted to the member 27. Suitable fastening elements 29 are extended throu h the

members

25,26,27, 28 and the part 14, an are properly clinched to aid in fasten- 9 ing all of these parts together. The cushioning element 19 is connected with the annular member 27 by the use of suitable fastening elements 30. In order to more securely. hold the resilient element 19 there is provided an annular fiber member 31 which surrounds the element 19 in contact with the fiange 21. The member 31 is connected with the part 14: of the element 10 by suitable fastening elements 32 which extend through the fiber member 26 as well as the part 14 and member 31, and are properly clinched against the member 31. The part 13 of the polishing or bufiing element 10 is cemented or pasted to the part 14 after the fastening elements 32 have been applied to complete the polisher or buffer.

Fromthe foregoing it will be apparent that there has been described a polisher or buffer which may be used for polishing, cleaning, and buffing polished or glazed surfaces, and that by virtue of the intervention of the cushioning means 12 excessive thrust pressures will be absorbed while the device is in use, thereby overcoming the possibility of the work being scorched, marred or burned.

I claim:

1. A polishercomprising a polishing element in the form of a felt disk, a spindle, a

cup-shaped rubber element having an inner and outer edge, said rubber element being connected with said spindle by means consisting of plates connected with the spindle and respectively disposed on opposite sides of the inner edge of said rubber element, and a ring member engaging the outer edge of said rubber element, said ring member being connected with said polishing element.

2. A polisher comprising a disk shaped felt polishing element, a spindle, a cup shaped element of rubber having an inner edge and an outer edge, means securing the inner edge of said cup shaped element to one end of said spindle, and means securing the outer edge of said cup shaped element to said polishing element at the back within the circumferential ed e thereof.
