J. J. SARRAZIN.-

' TOOTH BRUSH.

APPLICATION FILED JULY 14,1911.

1,018,927. Patented Fb.27, 1912.

Suva/"toe I 1' 9 6410mm,

' denotes the handle of the brush, and a is the UNITED STATES Jones J. SARRAZIN, or new ORLEANS, LOUISIANA.

TOOTH-BRUSH.

1,018,927. Specification of Application filed July 14,

To all whom it may concern I Be it known that-"I, JULES J. SARRAZIN, a citizen of the United, States, and a resident of New Orleans, in the parish of Orleans, State of Louisiana, have invented certain new and useful Improvements in Tooth-Brushes, of which the following is a specification.

This invention has for its object to provide a tooth brush which is so constructed that it will more readily and thoroughly cleanse the teeth and be more readily controlled by the user than the ordinary tooth brushes now on the market, and to this end it consists in a novel arrangement of bristle tufts and a construction to be. hereinafter described and claimed.

In order that the invention may be better understood, reference is had to the accompanying drawing, in which ,Figure 1 is a plan' view of the brush; Fig. 2 is a side elevation of the brush head, and Figs. 3 and .4.- are longitudinal and transverse sections, respectively, of the brush head. i

Referring specifically to the drawing, A

head, the latter being tapered in the direction of its forward end and joined to the handle by an elongated neck a, which latter allows free manipulation of the brush in all parts of the mouth, and around the teeth and the gum margins without hindrance by the muscles and tissues of the mouth and cheeks of the user, and, consequently, with greater comfort.

At the forward end of the brush head are several tufts of bristles which are bunched or grouped closely together to form a prominent projecting point B. The bristles of this group are cut so that the contour thereof is given a transverse and longitudinal curve. The remaining tufts of bristles b of the brush head extend in converging longi tudinal rows from the rear end of the brush head to the point B, and they are also arranged in straight rows extending transversely of the brushhead. The number of tufts in the transverse rows is not uniform, the forward rows having a less number than the rear rows. As shown in Fig. 1. of the Letters at n Patented Feb. 27, 1912.

1911. Serial No. 638,547.

each extend from the rear end to about the middle of the brush head, and between the latter and the point B are three rows of three tufts each. Of course, the number of tufts in the transverse rows may be varied, provided the forward rows contain a smaller number than the rear rows.

By the herein-described arrangement of tufts b it is possible to produce a short the forward end thereof except at the point B. It is desirable to have the tufts spaced from eachother in order that they may get between the teeth. Without this reduction of numbers of tufts in the forward transverse rows, the tufts would betoo solidly massed at this portion of the brush and they would therefore be prevented 'from passing freely between the teeth.

The bristles b are cut or arranged so that acentral longitudinal groove 0 ishad,which groove, however, does out the entire length of the brush head, but stops short of the point B. As shown is in the first one of the transverse rows having the smaller number of tufts, thus which is next rear end of'the brush head, from which it gradually decreases in depth and width up to the end 0'- v The herein-described groove 0 serves to guide the brush along the edge, of the bicuspids and molars of both the upper and lower jaws, and thus holds the point B to .itsyproper working position along the gum margins.

I claim A tooth brush having a short head which is tapered toward its forward end, and bristle tufts on said head arranged to form an elevated point at head, and said head also having, bristle tufts arranged in longitudinal and transverse rows, the longitudinal rows converging in the direction of the forward end of the head, and the number of tufts in the transverse rows at the forward end of the brush being less than that in the transverse drawing, four transverse rows of four tufts rows to the rear thereof, and said tufts betapered brush without bunching the tufts at I leaving intact the other transverse row to the point B. The deepest and widest. portion -of the groove is at the not extend through-.

in Fig. 3, the groove terminates at C which 7 the forward end of the;

ing arranged to form a central, longitudinal aflixed my signature in the presence f two groove which commences at the rear end of the head and terminates at'a point-spaced fromthe elevated point, andsajd groove de- 5 creasing in depth and Width toward the forward end of 'the head. I y

In testimony whereof, I have hereunto witnesses;
