Application March 19, 1947, Serial No. 735,713

1 Claim. 1

This invention relates to bufiing, polishing or grinding machines whose principal object is to provide a structure that will be compact so that it can be accommodated in a relatively small space and be convenient for home use.

Another object is to provide a structure that will be simple, of a relatively light weight and cheap to manufacture.

Still another object is to arrange the bufiing Wheels and the motor driving the same so that the centrifugal forces thereof will counter-balance one another.

And still another object is to mount all operating parts so as to reduce vibrations to a minimum.

Another object is to provide automatic means for the removal and collection of the dust directly from the region around the bufiing wheels.

With these and other objects in view that will be apparent from the detailed description of my invention the latter substantially consists in the novel construction, combination and arrangement of parts as will be hereinafter fully described and defined in the appended claim.

In the accompanying drawing which constitutes part of this specification and in which similar reference numerals denote corresponding parts;

Fig. 1 is a perspective View of my new buffing machine;

Fig. 2 is an end view thereof;

Fig. 3 is a top plan view thereof, and

Fig. 4 is a rear view thereof.

Referring more in detail to the drawing, my machine comprises a base It, an upright wall I l fixed on said base, a platform l2 projecting from one side of said wall and a bufiing wheel support l3 projecting from the opposite side of said wall. To reduce the weight of the machine, the wall, platform and support may be constructed from seamless pipes I4 covered by steel or aluminum plates I5, I6 and il, suitably welded together.

Suitably fixed to the front end of the support l3 are bearings is (only one being shown) for a horizontal shaft I9 on which are fixed the buffing or polishing wheels 20. The support i3 is advantageously made in form of a hood to enclose the means for transmitting motion to the shaft 19, as belt or gears, from the motor 21, mounted on the opposite side of the wall H. Suitably supported on the base I below the platform I2 is a dust collecting chamber 24 in which is mounted a suitable rotary blower, whose shaft 25 may be driven from the motor 21 through 2 pulleys and belt 25, 26, respectively, or in any other suitable manner.

Suitably fixed to the support I3 to envelop the upper parts of the wheels 29 are semi-cylindrical shields 28. Attached to these shields and opening into the spaces directly around the wheels are conduits 21 which extend through the wall H and platform l2 and terminate in the dust collecting chamber 24.

The construction of the machine is such that the parts on one side of the upright wall are adapted to counterbalance those on the opposite side, so that in operation vibration will be considerably reduced.

What I claim is:

As an article of manufacture, a bufling machine or the like, comprising a base plate, an upright plate wall mounted thereon, a horizontal platform projecting from the rear face of said wall, a motor mounted on said platform, adjacent to the rear face of said wall, a housing projecting centrally and forwardly from the upper part of the front face of said wall, a horizontal shaft extending parallel to said wall in the plane of the axis of said motor, and borne in the forward end of said housing, bufiing wheels fixed on said shaft, one on each side of said housing, a motion transmitting means for said shaft from said motor, concealed within said housing, a dust collecting chamber mounted on said base plate at the rear of said wall below said platform, rotary means for creating suction in said chamber, means for transmitting motion to said suction creating means from said motor, shields mounted above said buffing wheels and conduits connected to and leading from within said shields through said wall into the dust collecting chamber.

CARL J. GEIGER.
