POLISHING'IMPLEMENT.

SPECIFICATION forming part of Letters Patent No. 743,685, dated. November I, 1903.

Y Application filed March 9 1903. Serial No. 146,807l (No model.)

To LZZ whom, it may concern/.-

Be it known that I, ERNEST E. BRoADHUns'r, a citizen of the United States of America, residing at Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvements in Finger-Nail Polishers, of which the following is a specification,`

reference being had to the accompanying drawings, forming a part thereof. l

My invention relates to polishing implements, and particularly to that class of polishin g implements employed for polishing the the air compressed Within the air-chamber will tend to force the polishing material out through the said perforations. The hollow chamber may be conveniently formed in a single integral portion .of molded rubber, which may be attached to a suitable backing and which may have a charging-orifice in its rear Wall for the purpose of charging `or recharging the hollow chamber.

I will now proceed to describe a polishing implement embodying my invention and will then point out the novel features in claims.

In the drawings, Figure lis a view in side elevation of a polishing implement embodying my invention. Fig. 2 is a top view thereof. Fig. 3 is a view in of same. Fig. it is'a similar longitudinal section showing a slightly-modified form.

Referring more particularly at first to Figs. l to 3, inclusive, lthe implement comprises a suitable backing l and a flexible resilient polishing member 2, suitably supported therefrom. In the present example of my invention the polishing member 2 comprises one wall of a chamber 3, inclosed by an integral portion Whose rear wall Ll is directly supported by the backing l. In order to secure the parts together, the Wall 4 and backing 1 are provided with a dovetailed engagement, as at 5. The rear wall -t of the chamber 3 is provided with a charging-orifice 6, through which polishing material may be inserted into the inlongitudinal elevation. Lp

than thebacking portion terior ofv the chamber 3 and which may be closed by the backing l, or, Tas shown in Fig.

e, the charging-orifice 6 may be inline with a similar orifice 7 in the backing I, which may be closed by a removable plug or cap S, so that the chamber 3 may be charged or recharged without removing same from its backing-support. The front wall or polishing member 2 is shown as provided with a n umber of dischargeperforatibns 9, through which polishing material contained Within the chamber 3 may be discharged. A polishing implement of this description is invariably used in an upright position,in which position it is shown in the drawings. In such position the polishing material within the chamber 3 will tend to close the discharge-orifices 9, (which discharge-orifices are very minute, preferably more so proportionately than is shown in the drawings,) and when pressure is applied to the polishing-surface, air confined in the chamber 3 between the rear of the polishing material and the rear wall of the chamber will tend to force vthe polishing material through the dischargeorifices in minute quantities as will be required. When the chamber 3 is emptied, it may be rapidly relled through the chargingorifice 6. The polishing member 2 must be of a material which is flexible and yet resilient in order that it may have a normalv tendency to retain its correct shape. I preferably employ rubber or rubber compound for this pirpose, vulcanized to a degree sufficient to give it the required flexibility and resilience. In fact, I preferably form the entire ortion which incloses the chamber 3 other 1 of rubber or rubber compound so vulcanized. The backing l may be of any suitable material, as of Wood, as iscommon to this class of implements.

The flexible resilient polishing member 2 may, if desired, be provided with an outer layer of chamois-skin or other material to constitute the polishing-surface, as illustrated at 10 in Fig. LL, or the iiexible resilient material of which the member 2 is itself composed may constitute the polishing-surface.

What I claim is- 1. As an article of manufacture, a lingernail polisher, comprising an elongated base forming on one side abacking for a polishing' member, and provided on the other side with ICO a handle, and a iiexible resilient polishing member inclosing an air-chamber, secured to said base.

2. AS an article of manufacture, a fingernail polisher, comprising an elongated base forming on one side abackingforapolishing member, and provided on the other side with a handle, and a li'exible resilient polishing member com posed of rubber and inclosing an air-chamber, secured to said base.

3. As an article of manufacture, a fingernail polisher, comprising an elongated base forming on one side a backing for a polishing member, and provided on the other side with a handle, and a flexible resilient polishing member inclosing an air-chamber, secu red to said base, said air-chamber adapted toreceive and hold a polishing material, and said polishing member provided with dischargeperforations thereforin its polishing-surface.

4. As an article of manufacture, va fingernail polisher, comprising an elongated base forming on one side abacking for a polishing member, and provided on the other side with a handle, and a flexible resilient polishing member inclosing an air-chamber, secu red to said base, said implement provided With a charging-opening con necting with the interior ofthe said chamber, and closed during the operation of the device, and with dischargeperforations through its polishing-surface.

5. In a fingernail polisher,the combination with an elongated base forming on one sidea backing for a polishing member, and provided on the other side with a handle, of a flexible resilient polishing member inclosing an airchamber, secured to ing member having discharge-perforations through its polishing-surface, and polishing material loosely contained Within said airchamber.

6. In a linger-nail polisher, the combination with an elongated base forming on one side a backing fora polishing member,and provided on the other side with a handle, of a flexible resilient polishing member inclosing an airchamber, secured to said base, said polishing member having discharge-perforations through its polishing-surface, and provided with a charging-opening closed during the operation of the device, and polishing material looselycontained Within said air-chamber.
