Specification of Letters Patent.

Application led October 17,1911. Serial No. 655,128.

To all whom it may concern:

Be it known that I, FRANCIS W. SADL-ER, a citizen of the United States, residing at Norristown, in the county of Montgomery and State of Pennsylvania, have invented new and useful Improvements in Soluble Brushes, of which the following is a specilication.

An object of the invention is to provide a brush capable of becoming soluble when subjected to the dissolving action of a Huid.

My invention relates more particularly to a brush body, provided with projecting elements, soluble in water or theilike, so that when the brush is once used in connection with a fluid, the same cannot be reusedthus insuring perfect sanitation, .l particularly when my device is used as a tooth brush or the like.

Reference is to be had to the accompanying drawings constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in which- Figure 1 is a perspective view of the brush. Fig. 2 is a vertical sectional view taken substantially on the line 2-2 in Fig. 1. Fig. 3 is a perspective view of my brush showing the same in connection with a holder. I

Referring more particularly to the views, I provide a brush body 10, preferably rectan lar in shape and having the sides thereof slightly "inclined, the said brush body being adapted for slidable engagement with a holder 11, provided with a handle 12. Integrally formed on the brush body `10 and projecting upwardly Vtherefrom are a series of projections 13, such as bristles or teeth, the said projections being preferably conical in shape and composed of a substance which becomes soluble when subjected to the action of a fluid. The

brush body 10 and projections 13 are pref` erably made of a mixture of antiseptic formaldehyde tooth powder and paper pulp and an adhesive of an antiseptic or sanitary nature is mixed with the mentioned ingredients to act as a binder therefor.

In the use of my device, the brush body 10 is preferably mounted on a holder, such as the holder 11, shown in Fig. 3. Assuming that the particular brush disclosed is used as a tooth brush, when the projections thereof come in contact with the saliva in the mouth, the action of the saliva onthe projections will cause the same to become soluble so that after one application, the projections will be destroyed so that the brush cannot be reused, it being necessary to provide a new brush when it is desired to clean the teeth a second time.

From the foregoing description, it will be seen that a device is provided, which is absolutely sanitary in its application and use and in which the projections of the brush, being soluble are destroyed and rendered unfit for use after the first application thereof.

It will be understood that the projections mentioned herein can be fashioned similarly to bristles or teeth and that the scope of the invention is defined in the appended claims.

I claim l. A tooth brush having an acting surface composed of pointed protuberances of a material soluble and disintegrable under the infiuence of moisture and the rubbing action of said protu-berances against the teth, the said protuberances being impregnated with an antiseptic cleansing agent.

2. A tooth brush having an acting surface composed of pointed protuberances of a material soluble and disintegrableunder the influence of moisture and a rubbing action of said protuberances against the teeth, the said protuberances being molded from a material of the character described impregnated with an antiseptic, a cleansing agent, and an adhesive.

Patented Oct. 6, 1914.1

3. A tooth brush having an acting sur face composed of pointed protuberances molded from paper pulp, an antiseptic, a cleansing powder, and an adhesive, said protuberances being soluble and disintegrable under the iniiuence of moisture and the rubbing action of said protuberances against the teeth, whereby in the cleansing action disintegrated particles of the protuberances carrying the antiseptic a ent will be left in the interstices between t e teeth.

In testimony whereof I affix my signature in presence of two witnesses.
