Application filed February 27, 1928. Serial No. 257,246.

brush and is illustrated and described as a tooth brush. The invent-ion is a brush which has a bristle member formed so as to be removably secured to the handle so that one handle will serve for more than one brush.

The invention comprises a cleaning memher which has a back of resilient material that is distorted when being installed or removed from the handle but which is held in place on the handle by the resiliency. of the material.

The invention also relates to a cleaning member in which the back-otclcaning member and the tongues of the member are made of one piece to provide a cheap and substantial article and which is imperforate on the top to conceal and protect the holding means on the back of the member and concoiled by the member when in place.

The invention is illustrated in the accompanying drawings in Wl'ilCll Figure 1 is a section through the brush with; the upper part of the cleaning member in elevation. Figure 2 is a top view of the handle with the cleaning member removed. Figure 3 is a botton'i view of the cleaning member.

The handle 10 is provided with the cleaning member 11 which is made 01 one piece of elastic or resilient material, as rubber and consists of a back 12 and the tongues 18. The back is secured. to the handle and the usual construction is to form a recess-14C in the handle and the cleaning member forms an inlay which fits the recess.

The bot-tom of the recess is provided with studs such as the central stud 15 with a head on the top of it and side studs 16 with outwardly projecting heads 17 thereby forming undercut portions on the outer sides of the studs 16. The back 12 of the member 11 has recesses 18 which fit over these headed studs and when the member 11 is undergoing installation or removal it is distorted but when it is in place it resumes its normal shape and fits the handle. The undercut portions of the stud 16 receive the ends b1 the outer recesses 18 and thus not only hold the back 12 taut but tends to press down on the ends of the back 12 to hold the ends down.

The member 11 when in place covers the securing means and as the handle and member 11 are made of rubber and other material impervious to. water material can not accumulate to destroy or rot the article and it is a sanitary brush.

The tongues that are made of rubber are easier o clean than ordinary bristles as they are less in number and form no minute places for attachment of particles.

Tlhe Form and dimensions oi? the brushes,

of course, can be varied to suit the individual. I

taste and the bristles can be made of differentdegrees of hardness as will be evident.

I claim d f 1. A. tooth brush compr' ing a handle with a recess therein and with studs on the bottom oi the recess, said studs having outwardly projecting tops, and a back support ing tongues, the back having recesses and made of resilient material whereby the back can be stretched over the said tops and be held thereby.

2. A tooth brush comprising a handle with a recess therein, studs extending from the bottom of the recess, the outer of said studs hav ng outwardlyv projecting heads forming undercut portions, and a stretchable cleaning member including a back with recesses to receive the studs and which is stretched over said studs and held flat at its ends by the undercut portions.

In testimony whereof I affix my signature.-

GUSTAVE J. ESSBAGH.
