Application filed February 8, 1984. Serial I0. 891,080.

To all whom it may concern I Be it known that I, An'ron G. METRAKos, a citizen of Greece, residing at East Pittsburgh, in the county .of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Motor- Operated Brushes, of which the following is a specification. f

This invention relates to motor operated brushes and has for an object the provision of a brush which operates with a reciprocatory movement and which is especially adapted for use in bufiing and polishing.

Another object of the invention is the pro- |5 vision of a brush of the above character whose driving mechanism includes a rotary cam, the latter being operatively connected to the brush and providing a smooth and evenly driven brush.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings Figure 1 is a longitudinal sectional view of a brush constructed in accordance with the invention.

Figure 2 is a section on the line 2-2 of Fi ure 1.

igure 3 is a section on the line 3-3 of Fi ure 1.

Figure 4 is a detail plan view of the slide. Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the reference character 10 indicates a casing of suitable size and confi uration and which includes a slide 11.

so '1 is slide is mounted for reciprocatory movement in guide grooves 12 provided upon opposite sides 0 the casing and prw vides a sliding bottom for the casing. Secured to the slide 11 by means of fastening devices 13 is a brush 14, the bristles of which may be of an suitable material.

Mounted within t e casing 10 as shown at 14 is a motor 15 which may receive current from any suitable source. The shaft of this motor has secured thereon a pinion 16 which engages an internal gear 17. This gear is mounted upon a shaft 18 which rotates in suitable bearings 19 secured within the casing, while mounted u n the shaft '18 is a c linder 20. This cy inder is provided wit a cam groove 21 which receives a stud 22 secured to the slide 11.

It will be a parent from the foregoing description and accompanying drawings that the operation of the motor will, through the gearing described, rotate the c linder 20, while the engagement of the stu 22 within the cam groove 21 of this cylinder will impart a rec-iprocatory motion to the brush 14.

The invention is susceptible of various changes in its form, proportions and minor details of construction and'the right is herein reserved to make such changes as proper- 1y fall within the scope of the appended 0 mm.

Having described the invention whatis claimed is A motor operated brush comprising a housing, a brush mounted for sliding movement at the bottom of the housing, a motor secured within the housingabove the brush and having its shaft disposed longitudinally of said housing, a driven shaft mounted in bearings within the housing and disposed parallel to the axis of the motor shaft, an internal gear mounted upon the end of the driven shaft, a pinion carried by the motor shaft and engaging the gear, a cylinder provided with a cam groove and mounted upon the driven, shaft and a stud extending 5 from the-brush within the roove.

In testimony whereof I u 'x m si nature.
