TOOTH BRUSH Filed Jan. 18, 1958 5 1 K t I I JQM /r yen for.

Patented Aug. 8, 1939 UNITED STATES PATENT OFFICE TOOTH BRUSH Application January 18, 1938, Serial No. 185,617 In Germany August 12, 1937 3 Claims.

This invention relates to a tooth-brush, and particularly to the arrangement of the tufts of bristles to fit the arch of the teeth and thus effect thorough cleaning of the teeth including 5 the back thereof without hurting the gums.

According to the invention, the tufts nearest the longitudinal edge of the handle are directed obliquely toward the center and those closest to the longitudinal center incline outwardly. While retaining this fundamental arrangement other advantageous modifications thereof may be made by inclining some of the tufts and leaving others in vertical position.

By way of example, one form of the invention 15 is illustrated in the accompanying drawing, in which Figure l is a side view of the brush; Fig. 2, a section on the line II-II, of Fig. 1, on an enlarged scale; Fig. 3, a section on the line III-III, of Fig. 2; and Fig. 4, a section on the line IV-IV,

go of Fig. 2.

Referring to the drawing, the tufts of the same rows on the left and right-hand side of the handle are designated by the same numerals. On both sides of the center line, three rows of tufts are 25 provided on the back or handle I. In the row nearest the outer edge of the handle a vertical tuft 2 alternates with a tuft 3 which is inclined toward the center. The second row exclusively comprises vertical tufts 4, and the tufts 5 of the 30 third inner row are slightly inclined outwardly so as to prevent injury to the gums. The inclined tufts 3 and 5 of the outer and inner rows respectively are so arranged that they cross each other like a sawing jack. The two rows 4, 5 nearest 35 the center are disposed at a greater distance from one another than the other rows. A tuft B positioned at the front end of the handle I in the center between the two inner rows is shorter than the other tufts.

I claim:

1. A tooth brush having, in the brush plate thereof, a longitudinal series of spaced pairs of inclined brush tufts forming two rows, one member of each pair being oppositely and transversely b inclined from and longitudinally offset from the other so that the individual members of one row on one side extend across the plane of the members of the other row, and a vertical brush tuft between each pair of inclined tufts, the inclina-- 10 tion of the tufts in one of the rows of inclined tufts being greater than the inclination of the tufts in the other row.

2. A tooth brush having, in the brush plate thereof, a longitudinal series of spaced pairs of inclined brush tufts forming two rows, one member of each pair being oppositely and transversely inclined from and longitudinally offset from the other so that the individual members of one row on one side extend across the plane of the members of the other, a vertical brush tuft between each pair of inclined tufts and a vertical brush tuft laterally opposed to each of the inclined tufts on one row.

3. A tooth brush having a series of spaced lon- 26 gitudinal rows of brush tufts adjacent each side of the brush plate, said series comprising inner and outer substantially parallel rows of vertical tufts, the tufts therein being longitudinally spaced from each other, inner and outer rows of respec- 30 tively outward and inward inclined tufts, said inclined rows being arranged to provide an out wardly inclined tuft between each two vertical tufts in the inner rows, and an inwardly inclined tuft between each two vertical tufts in the outer rows, said inwardly and outwardly inclined tufts being respectively staggered and crossing one another.
