SANDPAPEBING AND BUIIIING MACHINE.

. Application fled Kay 8, 1996. Serial No. 106,441.

My present invention pertains to sandpapering and bufiing machines and it eontemplates the, provision of a simple, inexpensive and readily portable device through the medium of which automobiles or other highly polished surfaces may be easily and quickly polished, sand papered and otherwise buifed with but a slight amount of effort on the part of the operator. The invention further contemplates a portable sanding and bufling machine for the purpose set forth that is adapted for being readily interchangeable with respect to the bufiing element employed. 4

The invention in all of its details will be fully understood from the following des er1ption and claim when the same are read in connection with the drawings accompanying and forming .part of this specification, in which Figure 1 is .a side elevation of my novel device.

Figure 2 is an inverted plan view thereof. Figure 3 is a sectionaliview of'Figure 1. 35 Figure 4 is a View taken in the plan indicated by the line H of. Figure 1 and looking in the direction of the'arrows.

Figure 5 is a side elevation of a sand paperingelement that may be. substituted for the bufling element. 7

Similar numerals of reference designate corresponding parts in all the views of the drawings.

My novel device comprises a casing that is indicated asa whole by. 1 and the said casing is provided with the curved guar portions 2 and an edge'l'ower portion 3 and a'rran ed in the edge portion 3 is an indented surfaced at one end and an indente 4 surface 5. at the opposite end of the casing, the indented-portion 5'be1ng slightly larger than the portion 4, for a purpose hereinafter specified.

Secured to the forward portion of the cas- 6 that is heldto the casing by means 0 the bolts 7. This strap rests in the indented ortion 4 of the edge 3 and not only deplen s slightly below the edge 3 but is firmly eld against the casing and against side-wise movement by the abutting edges of the indented surface 4 of the edge 3'. Similarly secured at the rear portion of the casingas referred to in this specification is a bearing strap 8 that is secured to the casing by means of a bolt 9 and this strap rests between the abutting edges dto d tuation of the plished.'

of the indented ortion 5 of the edge portion 3 and depen s from the edge 3 approximately the same length or distance as the strap 6. These straps are similar in construction except that the strap 8 is adjustable which is accomplished by providing a semicircular slot 11 and adjusting bolt 10. The purpose of this adjustment 18 to take up-wear and the further purpose will be ap-- preciated by reference to the later description of the device.

Secured in the bearing strap, 6 is a shaft '12 and mounted on this shaft is a roller 13 whilesecured in the bearing strap 8 is a shaft 14 on which is arranged the spool-or drum 15. The roller 13 is in fact a drum similar to the drum 15.

Adapted to rotate through the medium of the

rotatable drums

13 and 15 is an endless belt 16 and in Figure 1 I have illustrated the belt 16 as provided with sheep wool or other high-grade bufiing material 17, but at this point I would distinctly have it understood that the endless belt may be provided with any bufling material, such for instance as sand paper, emery or the like. The endless belt 17 is readily adjustable by means of the adjusting boltand slot 10 and 11.

Mounted on and preferabl bolted to casing 1 is a light motor 18 t at is provided with a V type pulley 19 and adapted to rotate through means of the pulley 19 is a pulley belt 20 that in turn actuates a V type pulley 21 fast on the shaft 12. Apparently rotation of the pulley 19 will impart rotation the pulley 21 which in turn rotates the drum 19 thereby impartin' movement to the belt 16 and the drum 15. n this manner aobufiing element is. accom- In order to assist in the easy handling of the device I have provided a-handle 22 that is adjustably mounted at 23 on the casing 1.

Although I have deemed it unnecessary to illustrate nevertheless I would have it understood that the

drums

13 and 15 ma be .remov'ably arranged in the casing 1 an vreleased .through means of a trigger from the casing so that removal of one 'bufiing element and replacement ofanother may be accompliphe 'Any form of construction tilt-13x18 we 1 known in the art maybe emplo ed for this purpose and I make no speei c c aim to this arran emen "1 It must-lie borne in mind that the primary and salient feature of my invention is distinctly novel sand the device and though vicefor use as a bufiin that the improvements I papering'. 1

When desired the belt 24 having the sand Eager surface 25 may be substituted for the u g element 17.

palperin features of ave s own the demachine, I prefer e confined to sand earners walls of the machine; one of said straps being retained snuglyin one of the indentions and the other of which is ada ted to be adjusted with respect to the si e wall and'within the complementary indentions, a slot formed in one of the straps to enga 'e adjusting means, shafts 'ournalled in t e lower ends of the straps, rums mounted on the shafts, a bufling element arranged on an endless belt; said endless belt being actuated by the drums and means for actuating one of the shafts.

In testimony whereof I have hereunto set my hand. I
