J. CHANDLER RUBBER TOOTHBRUSH Filed July 1925 INVENTOR Ina-(vim ATTORNEYS Patented Mar. 23, 1926.

JERMAIN CHANDLER, OI TOLEDO, OHIO.

RUBBER [[OOTHIBRUSH.

Application filed July 28, 1925. Serial No. 46,647.

To all whom it may concern.

Be it known that I, JERMAIN CHANDLER, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Rubber Toothbrushes, of which the following is a specification.

This invention relates to an improvement in tooth brushes and aims to provide a tooth brush which is of simple yet strong and durable construction; which is highly sanitary especially in that no pockets or crevices are formed in its structure wherein dirt or germ breeding accumulations are liable to build up; which may be readily cleaned; which is designed and'ada ted to be operated with facility to the en teethwithout ab-rading or injuring the same; and which massages the gums in such a manner as to condition and preserve them against disease.

Other objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be hereafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawings forming a part of this specification and in which- Figure 1 is a perspective view showing one embodiment of the invention;

Figure 2 is a sectional view on line 2-2 of Flgure 1,

Figure 3 is a detail view of-the handle, and

Figure 4 is a detail view of the cleaning elements.

Refen lng to the drawings the numeral 1 war end constituted to provide a head or brush back 2. The back 2 is formed with a slot 3 extending entirely through the back and open on each side of the back. At each end of the slot 3, tongues 4 are provided, the tongues 4 being inte al and coplanar with the back and extend iiig toward each other from the end walls of the slot, as clearly shown in Figure 3 of the drawing the tongues 4 terminate shortof each other,

7 there being a substantial space 3 between the ends of the ton es, and these tongues also are narrower t an the slots to leave An elastic cleaning element designated of thoroughly and eifec-' tively cleaning all of the surfaces of the designates generally a. handle having its forgenerally at 5 is'provided and comprises a plate like body 6 of generally rectangular form which is preferably constituted of rubber or other flexible and elastic material. The body 6 comprises similar and portions 7 and 8 and a longitudinally reduced intermediate portion 9, the intermediate portion 9 being so reduced by forming notches 10 and 11 in the body 6. Integral with the portions 7 and 8 pointed rubber bristles 12 and 18 are formed, the portions 7 and 8 thus constituting bristle backs.

The cleaning element 5 is assembled with the handle 1 as clearly illustrated in Figures 1 and 2 and this assembly may be effected by slipping the end of the portion 9 adjacent the notch 10 over the rearwardly disposed tongue .4 and then buckling the central part of portion 9 to engage the end adjacent notch 11 over the forward tongue 4. In this way the intermediate portion 9 constitutes a mounting portion which is flexed and slightl tension'ed or straddled in the assembly to ring the elasticity of the body 6 into play to aid the interengagement between the cleaning element and the handle. The security of this interengagement is enhanced by virtue of the fact that the edges of the end portions 7 and 8 contiguous with the notches 10 and 11 present shoulders 14 and 15 engageable with the under face of the head 2 in the assembly. The action of these shoulders and the engagement of the mounting portion 9 with the tongues 4 afl'ords an effective interengagement of these parts. This mounting also results in the cleaning element taking a V-shaped form in the assembly, the bristle backs 7 and 8 diverging and thebristles 12 and 13 extending toward each other though angularly related.

With this brush all surfaces of the teeth may be-thoroughly cleaned without danger of injuring the teeth in any way. The backs of the teeth, the surfaces near the gum line and in between the teeth, all may be easily and efl'ectively cleansed. Along with this desirable action the gums may be massaged to condition and preserve them against disease.

The brush may be readily cleaned and the cleaning element readily removed and replaced. The open work head on the handle acilitates thorough and efiective cleaning and its open formation tends to prevent accumulation which would be liable to build up were blind recesses or pockets presented.

ll claim:

"1. A tooth brush comprising a handle having a head at one end formed with a slot extending entirely therethrough, tongues on the head projecting into the slot at the opposite ends thereof, said tongues being spaced from each other and tromthe side walls of the slot, and a cleaning element comprising a plate-like body of rubber having ,end portions constituting bristle backs and a longitudinally reduced intermediate mounting portion extended around the tongues, said end ortions having shoulders engaging the un erside of the head, said cleaning element being flexed to V-shaped form and slightly stretched whereby its inherent resiliency aids in holding it in position, and bristles integral with the bristle backs.

2. A tooth brush comprising a handle hav ing a head at one end formed with a slot extending entirely therethrough, tongues on the head projecting into the slot at the opposite ends thereof, said tongues being spaced from each other and from the side walls of the slot, and a cleaning element'comprising a plate-like body of rubber having ar acre end portions constituting bristle backs and an intermediate mounting portion extended around the tongues said cleaning element being flexed to V-shaped form and slightly stretched whereby its inherent resiliency aids in holding it in position, and bristles integral with the bristle backs.

3. A tooth brush comprising a handle having a rigid head at one end formed with a slot extending entirely therethrough, tongues on the head projecting into the slot, and an elastic cleaning element having a body flexed to give the element a V-shaped form, said body having a mounting po'rtion accommodated in the open slot and engaging the tongues.

4. A tooth brush comprising a handle having a head and an elastic cleaning element flexed to substantially V-shaped form, cooperative sets of bristles on the angularly disposed portions of the cleaning element, the set of bristles of one angular portion being directed toward the set of bristles on the other angular portion, and interengaging parts on the handle and cleaning element for holding the same together, the cleaning element being slightly stretched to hold the parts to'gether.
