Description

VALTER G. STOUT,VOF CAMDEN, NEW JERSEY, AND HIRAM O. COWDRICK, -OF PHILADELPHIA, PENNSYLVANIA.

TOOTH-BRUSH.

SPECIFICATION forming pare of Letters Patent No. 540,884, dated June 11, 1895.

Application led November 2, 1893. Serial No. 489,805| (No model.)

To a/ZZ whom it may concern@ Be it known that we, WALTER G. STOUT, residing in the city and county of Camden, State of New Jersey, and HIRAM O. CowDRroK, a resident of the city and county of Philadelphia, State of Pennsylvania, citizens of the United States; have invented a new and useful Improvement in Tooth-Brushes, which improvement is fully set forth in the following specification and accompanying drawings.

Our invention consists of a tooth brush formed of a handle having a reservoir thereinv for tooth-wash or fluid, a nozzle for directing the latter to the head of the brush, means for permitting the supply andV preventing the escape of the fluid, and a removable head which provides access to the nozzle, so that thesame may be closed when the reservoir is to be replenished, and permits the substitution of fresh bristles or a rubbing portion when the latter is worn out, the construction and operation of parts being hereinafter more fully set forth.

Figure l represents a side elevation of a tooth-brush embodying our invention. Fig. 2 represents a longitudinal sectional view thereof. Fig. 3 represents aface view thereof, the head of the brush being removed. Fig. 4 represents a transverse section on line oc Fig. l.

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

Referring to the drawings, A designates the handle of the brush, and B designates the back of theirubbing portion thereof, said back being open and having flanges C on its sides to receive and hold the head D of the bristles or rubbing portion, said head as is evident being removable from said back. The handle is hollow forming a reservoir, and terminating .on its inner end in a nozzle E, which is in line with the face of the head D, and has its discharge end at the inner end of the back B, so as to direct the ow of the'` wash across the face of the said head D.

On the outer end of the handle :is a screw plug or cap F, which closes said end, for preventing the escape of theV tooth-wash or fluid thereat. In the side of the handle, near said outer end is an air vent Gr, which when the plug F is in position, closes said vent, and prevents the entrance of air into the handle.

end of the handle are closed, the head being.

also replaced. When thebrush is to be used,

the plug is removed sufficientlyv to uncover the vent, whereby the wash will flow through the nozzle across the face of the back D and supply the bristles or rubbing portion with the wash. l NVhen service of the brush is no llonger required the plug is operated to close the vent, when kthe supply of wash ceases, and improper escape of the same is prevented.

When the bristlesor rubbing portion wear out, the head may be withdrawn and substituted by a fresh one with bristles or portion, and the brush render service as before, the head sliding on the back between the flanges C, both in removal and reapplication.

It will be noticed that the nozzle does not pass through either of the backs B or D, but its discharge end is at one end of the face of the back D, so that the ow is across the said face, and not through said head, which latter is imperforated or solid whereby the Wash is thoroughly distributed to allot the bristles. This construction not weakening the backs by having openings therein, furnishes a more durable article.

Having thus described our invention,what

-we claim as new, and desire to secure by Letters Patent, is-

As a new article of manufacture, a tooth brush consistingof a hollow handle,a nozzle, and a back with side flanges formed of a single piece of material, a detachable head titting in said flanges, and a plug closing the inlet of the handle, the discharge end of the nozzle being at the inner end. of the brush, said parts being combined substantially as described.
