- Inventors I f'azuardfilaiyke Jams 425M 2710 Patented Feb. 9, 1932 UNITED STATES PATENT OFFICE EDWARD J. PLETZKE AND JAMES J. SHARPE, OF DETROIT, MICHIGAN TOOTH'BRUSH Application filed March 26, 1931. Serial N'o. 525,576.

This invention .relates to a tooth brushand has for its primary object to provide, in a manner as hereinafter set forth, a device of this character embodying the novel construction and arrangement of parts, whereby a supply of tooth paste may be kept always at hand, the invention further contemplating novel means for dispensing or ejecting the tooth paste into the bristles of the brush in an economical and sanitary manner.

Other objects of the invention are to provide a tooth brush of the character described, which will be simple in construction, strong, durable. compact, eflicient and reliable 1n use and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection w th the accompanying drawings, wherein like characters of reference designate corresponding parts throughout the several views, and wherein Figure 1 is a perspective view of a tooth brush in accordance with this invention.

Fig. 2 is a perspective view showin collapsible paste tube, the cyhnder WhlC receives the paste tube and the head or enlargement of the brush WlllCh receives the cylinder separated from each other.

Fig. 3 is a view in longltudinal section through the device.

Fig. 4 is a view in elevation of the brush with the cap or cover removed.

Fig. 5 is a cross sectional view taken sub stantially on the line 5-5 of Fig. 3. I

Fig. 6 is a cross sectional view taken substantially on the line 66 of Fig. 3.

Fig. 7 is a cross sectional view taken substantially on the line 7-7 of Fig. 3.

Referring to the drawings in detail, it will be seen that the numeral 1 designates the bristles of the brush which project from the back 2. A shank 3 is formed integrally with the back 2 of the brush and terminates, at its free end in an externally threaded enlargement 4, which is threadedly engaged in the internally threaded cylinder 5 which is open at its inner end to receive the enlargement the vention as claimed.

4 and which is closed at its outer end, as indicated at 6.

A duct or passage 7 extends through the shank 3 and the back 2 and communicates with the side or of the face of said back 2 in which the bristles 1 are mounted, as clearly seen in Fig. 8 of the drawings. At its other end, the duct or passage 7 merges into a flared mouth 8 in the enlargement 4 which receives the tapered, apertured end portion 9 of a collapsible tube or container 10 which is disposed in the cylinder 5. I

The tube or container 10, is of course, adapted to contain the tooth paste. An elongated cap or cover 11 is provided for disposition over the blunt portion of the device, such cap or cover being closed at its outer end, as at 12, and having its inner end open to telescopically receive the inner end portions of the cylinder 5, the cap or cover 11 being frictionally engaged with the cylinder 5, thus facilitating the quick removal thereof when desired.

A resilient clip 13 is mounted longitudinally on the inner end portion of the cap or cover 11 to permit the device to be conveniently secured against accidental displace ment or loss in one pocket.

In use, the cap or cover 11 is removed. and the cylinder 5 is threaded inwardly over the enlargement 4 in a manner to compress the tube 10, thus ejecting the contents of said tube through the duct 7, into the bristles 1.

It will thus be seen that any desired amount of the paste may be ejected. It will also be readily apparent that the cylinder 5 provides a convenient handle when using the tooth brush. When the tube 10 becomes empty, it is only necessary to remove the cylinder 5 to permit a full tube to be inserted therein.

It is believed that the many advantages of a tooth brush constructed in accordance with this invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction may be had which will fall within the scope of the in Having thus described our invention what we claim as new is A tooth brush comprising aback having bristles projectin from one face thereof, an elongated shank ormed integrally with the back, an enlargement formed integrally on the free end of the shank, said enlargement belngl externally threaded, the back and the shank having a duct extending therethrough from the free end of the shank to the face of the back upon which the bristles are mounted, said duct merging with a flared mouth portion in the enlargement, a cylinder threaded for longitudinal adjustment on the enlargement, and a collapsible paste tube disposed in the cylinder, said tube including a conical end portion having a discharge opening, said conical end portion projecting into the flared mouth in the enlargement, the discharge opening registering substantially with the duct, the cylinder providing a handle for the tooth brush and constituting means for collapsing the tube in a manner to "eject the aste therefrom through the duct to the ristles.

In testimony whereof we aflix our signatures.
