TOOTH BRUSH Original Filed Feb. 18, 1955 Patented Nov. 2, 1937 UNITED STATES PATENT OFFICE TOOTH BRUSH Charles Edward Phillips, Fresno, Calif., assignor of one-fourth to Thomas Clarke Greene,

Fresno, Calif.

3 Claims.

This invention relates to a tooth brush, and an important object of the invention is to provide a tooth brush having the bristles thereof formed and arranged to clean the teeth and massage the gums at the same time and perform this work more efiiciently and quickly than is possible with present types of tooth brushes.

This invention also consists in certain other features of construction and in the combination and arrangement of several parts to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Fig. 1 is an edge view of the improved brush.

Fig. 2 is a view looking towards the bristlecarrying face of the brush.

Fig. 3 is a section on line 3-3 of Fig. 2.

Fig. 4 is an end view looking towards the bristles.

Fig. 5 is a section on line 5-5 of Fig. 2.

In this drawing, the numeral i indicates the handle of the brush and the numeral 2 the brush head and in carrying out the invention, I provide longitudinally extending rows of intermediate bristles 3 which are relatively short and are cateizl' between the outer longitudinally-extending rows of bristles 4 and each of these rows 4 has a number of bristles at each end which are relatively long as shown at 4' and the intermediate bristles of each row 4 being relatively short as shown at 4". Each bunch of bristles is tapered as shown and the bunches of bristles slope inwardly and downwardly excepting the middle bunch of each row as shown more particularly in Fig. 1. The bristles of the two outer rows ,converge from the head as shown in Figs. 4 and 5.

The long bristles 4 are longer than those in an.

one outer row engaging the outside faces of the,

teeth and the bristles of the other outer row engaging the inside faces of the teeth, the brush being moved back and forth and longitudinally over portions of the row of teeth. Thus the short intermediate bristles will clean portions of the biting ends of the teeth, while the outer rows of bristles will engage the inner and outer surfaces of the teeth and massage the gums and the long bristles will grip the necks of the teeth and clean in between the teeth. Thus the improved brush will grip the teeth and clean in between the teeth, the outside and inside surfaces and the biting ends of the teeth and also massage the gums on the forward and backward strokes of the brush.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

I claim:

1. A tooth brush of the class described comprising a handle and a head part, longitudinally extending rows of bunches of bristles carried by the head part, the bunches of the intermediate rows being relatively short and the bunches of bristles at the ends of the outer rows being relatively long; the central bunches of said outer rows being relatively short, the long bunches of bristles of the two outer rows converging both longitudinally and transversely from the head.

2. A tooth brush of the class described comprising a handle and a head part, longitudinally extending rows of bunches of bristles carried by the head part, the bunches of the intermediate rows being relatively short and the bunches of bristles at the ends of the outer rows being relatively long, the central bunches of said outer rows being relatively short, the central transverse row of bunches of bristles extending from the head substantially in a transverse plane extending at right angles from the head and all the other bunches converging longitudinally from the head, with the bunches of said outer rows also converging transversely from the head.

3. A tooth brush of the class described comprising a handle anda head part, said head part having a flat face, longitudinally extending outer rows of bunches of bristles extending from said face, the bunches of bristles at the ends of said rows being relatively long and converging both longitudinally and transversely, and an intermediate longitudinal row of short bunches of bristles extending from said face.
