TOOTHBRUSH.
Reled for abandoned application Serial No.' 717,820,`1ed June 4, 1924. This application led October 26,

This invention relates to .atooth-brush comprising a brush back anda handle in substantial alinement with the back, and flexible brush material, projecting from` one side of the back.
The object is to providean improved arrangement of the brush material, whereby,
when the brush is manipulated in the usual manner, and moved endwise forward and backward over the teeth, the brushing element forces refuse matter removed from the teeth toward longitudinal edges of the back and prevents said matter from accumulating within the brush material. U
Of the accompan ing drawings forming a part of this speci cation,"
Figure 1 is an edge view of atooth brush, embodying the invention.
Figure 2 iis a side view of the same, looking toward the inner side. Y
The same reference characters indicate the same parts in all of the figures. l
`The brush includes an oblong brush back 12, and a handle 13, in substantlal alinement with the back, so that the back and handle have a common longitudinal median line, the
back and handle being of anysuitable rigid material and usually in one piece.
The brushing element may be of any suitable flexible brush material, such as bristles 14 (Figure l), usually employed in tooth brushes and fixed to the back in any suitable manner, to project from the inner face thereof. It may be assumed that the stippling shown by Figure 2 represents the ends lof bristles, although I do not limit myself to bristles as the brush material.
The brush material is disposedl in an inner and an outer series of substantially parallel,
oblong rows, whose sides are substantially perpendicular to the back face from which they project. Said rows are spaced apart as shown by Figure 2, to provide'refuse channels between their adjacent sides 16. The rows ofthe outer series extend obliquely in one direction from the outer end portion to the midlength portion of the back'12. The rows of the inner series extend obliquel in a different direction from the midlength portion to the inner end portion of the back, 5o all as shown by Figure 2. The arrangement shown and described is such that when the back is reciV rocated endwise in the operation of brus ing teeth, refuse dislodged by the sides 16 of said rows is delivered to they channels between the rows and passes through said channels toward the longitudinal edges of the back, one series of rows. and the channels formed thereby acting to dislodge and deliver refuse at one longitudinal edge of the back, when the back is moved in one direction, and the other series of rows and channels acting similarly, when the back is moved in the opposite direction.
I prefer to space apart the outer and inner series of row groups at the midlength portion of the back, to provide between the groups a transverse refuse outlet, indicated at 18 inFigures land 2, said outlet communicating ywith the channels between the rows, and extending to the longitudinal edges of the back, at the midlength portion thereof.
I claim:
1. A tooth-brush comprising anA oblong back, a handle longitudinally alined/therewith, so thatk the back and handle have a common longitudinal median line, and ilexible brush material projecting from the inner face of the back and disposed in Van inner and an outer series of` substantially parallel oblong rows whose sides are substantiall perpendicular to the back face from which they project, said rows beingspaced a art to provide refuse channels between t eir adjacent sides, the rows of the outer series extending obliquely in one direction from the outer end portion to the midlength portion of the back, while the rows of the inner series extend obliquely in a different direction from said Vmidlength portion to the inner end portion of the back, the arranger ment being such that when the back is reciprocated endwise, refuse dislodged by the sides of said rows, is delivered to said channels and passes therethrough toward the longitudinal edges of the back, one series of rows, and the channels formed thereby, actasV ing to dislodge and deliver such 'refuse at one longitudinal edge of the back, when the back is moved in one direction, and the other series acting similarly, when the back is 5 moved in the opposite direction.
2. A tooth-brush as specified by claim 1, the outer and inner series of groups being spaced apart at the midlength portion of the back, to provide a transverse refuse outlet communicating with the channels be- 10 tween the rows.
In testimony whereof I have aiiiXed my
