IMPROVED HAND-BRUSHIG AND POLISHING-APPARATUS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I,' WILLIAM H. WILLSON, of the'city, county, and State of New York, have invented certain new and useful Improvements in Hand-Brushing aud Polishing-Apparatus; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had, to the accompanying drawings, making a portion of this specication', i n which- Figure 1 is a longitudinal section `of an apparatus made according to my invention.

Figure 2 is a transverse section of the same, taken in the line :e :e of iig. 1.

Figure 3 is a transversesection of the same, taken in the line y y of iig. 1.

Figure 4 is a transverse section of the same, taken in the line z z of grl.

Similar letters of reference indicate corresponding parts in all the figures.

This invention consists in-a coiled spring and a systen of gearing arranged within the cylindrical body of a rotary brushing and polishing-device, furnished with suitable axial handles, in such manner as to produce the requisite rotatory movement ofthe same, the object being to provide a rotary apparatus for the purposes indicated, which may be operated by hand, thereby dispensing with power as ordinarily applied to this class of devices.

The invention further consists in so arranging a friction-brake within the cylindrical body just named that the rotatory movement olf/'the latter may be readily stoppedwhen desired.

The invention further consists ina novel combination of.parts,vwhereby the eicient operation of the apparatus, and the convenience with which it may h'e handled or manipulated, is materially increased.

To enable others to understand-the construction and operation of my invention, I will proceed to describe it with reference to the d-rawingsil A represents avfraxne, composed of two circular disks, a ,`and an end bar, e, these parts being connected by suitable braces, a', working inA bearings provided in the disk b and bar c. V

In the axial line ofthe'cylindrical body B, hereinafterdescribed, is a stem, C, this stem being provided, at its outer end, with a handle,vA*. i v

Between the bar c und disk b is a coiled spring, D, shownin fig. 1, and also indicated in red outline in iig. le The inner end of this spring is attached to the stem C, and the outer extremity thereof is connected with' one of the braces a, ofthe frame A, in such a way that the uncoiling of the spring will rotate the stem Cjust mentioned lwith reference to such frame. t v

The stem C has attached thereto a ratchet-wheel, d, and placed loosely thereon is a spur-gear, e, furnished at one side with a spring-pawl, b', working with or into the ratchet-wheel Z in such manner thatw during the uncoiling of the spring the spur-gear e will be turned with the stem C, but in the ceiling of the spring the pawl will slip over the ratchet-wheel, thereby enabling the apparatus to be wound up for use.

The spur-gear gears into n pinion,f, upon a shaft, e', which extends from on`e of the disks a 6to the other,

and is provided with a spur-wheel, g, which,n acting through a pinion, z, spur-wheel z", and pinion j, rotates a shaft, e', upon the extremity of which, at the inner side of the disk 6, is a friction-pinion, m, which is placed in contact 'with the inner edge of an internal cylindrical shell, E, which is secured upon an axial shaft, E', furnished at its outer end with a handle, B*, and having its 'inner endscrewed firmly into `the centre of thedsk of the frame A. 4 I

Secured externally upon the lshell E is the cylindrical body B of the apparatus, the shell just mentioned being formed, in the first instance, separately from the body, merely for the sake of convenience iu construction, and constituting, in fact, a portion of the`body itself. Y I

The exterior of the body B, when the apparatus is to be' used for brushing purposes, is provided with radial bristles, :1s represented in red outline in igs. 1 and 4, 'out when designed for polishingv purposes, the surface of such body is coated with emery, or equivalent ubrading-materinl. I i

lhe springs 1 ),'having been coiled by turning the handle A* of tbe stem C in the requisite direction, operates,l when unwinding or uncoiling, through the stem C and the system of gears hereinbef'ore described, to rotatethe friction-pinionm, which, in its turn, communicates a rotatory movement to the body B, the body being held or sustained bythe handle B* in suitable contact or proximity-with the article to be brushed or polished, as the oase may he, the other handle, Al, that ofthe stem C, being left loose orvonly slightly supported by the hand of the person using the apparatus, so that it may be free to turn in the operation of the latter, as just hereinbefore described. v e

In order'that the apparatus may, when required, be retained vvith its spring in a coiled or wound-up condition, and that its movement may be stopped with facility when desired, a brake, consisting of a se'micircular spring, I, is secured, at its middle, to a plate, 0*, fixed upon the shaft F, at the inner end of the handle B* thereof, the end portions of such brake,.when the latter is expanded, beingpressed against the interior of the shell E, or, in other words, ofv the body B, with s'uicie'ntforce to neutralize that exerted by the coiled spring D, which operates to rotate such body, ,thereby stopping the movement of the latter.

Extending from one end portion ofthe spring or brake I to the other, is a chain or strap, 1', the centre of which is attached to the inner end ofa lever, 11 passing through the plate 0*, with its opposite end situated in such relation with the handle B* that it may be conveniently pressed toward the 'same to draw upon the chain or strap just mentioned, so as to bring the end portions of the brake inward away from the internal surface of the shell E, thereby permitting the rotation, as hereinbefor'e set forth, of the body B, of which such shell forms a part, it being only necessary to release the lever 'in order to permit the brake to operate to stop the motion of the body B, as just mentioned.

What I claim as my invention, and desire to secure by Letters Patent, isf

1. So arranging the coiled spring and the system of gearing within the cylindrical body furnished with axial handles, as to secure the rotatory movement of such body, substantially as herein set forth.

2. The arrangement of the friction-brake within the cylindrical body furnished with axial handles, whereby the rotatory movement of the same may be stopped, substantially as herein set forth.

3. The arrangement of the coiled spring, the system of gearing, the stem ofthe handle A*, and the frame A, with reference to eachother and the friction-pinion m, dividing the cylindrical body B, substantially as and for the purpose specified.
