2 Claims.

This invention. relates to a tooth brush and more particularly pertains to the construction of the handle thereof.

Some of the distinguishing features and advantages of the invention are as follows: Enables the user of the brush to get a more natural and firmer grip so that the tooth-brush may be manipulated in any position with the advantage of such grip. It prevents the thumb ani index finger of the users hand from slipping forward when the brush is held and in use so that the brush may be eiectually employed in brushing the teeth and massaging the gums of both the arches. The brush when not in the common and conventional holder or receptacle and the bristles remain elevated above the surface of the holder so that none of the bristles come in contact with ysuch surface. 'By avoiding such contact there is eliminated entirely the common condition of the bristles resting in and upon such matter as may and usually does settle and form on the surfaceof the holder or receptacle. This elimination leaves the brush and especially the bristles in a more sanitary condition. The resting position oi the brush also permits the bristles to drain more quickly and to dry more thoroughly and completely. It also prevents the distorting or bunching of the. bristles and reduces the possibility of the saine decaying. The wear upon the bristles is also lessened. These mentioned features and advantages in turn result in prolonging 4the life and usefulness of the brush.

In the accompanying drawing- Fig. 1 is a side View of a brush embodying the features of the invention;

Fig. 2 is a back view;

Fig. 3 is a side view of the brush and in dotted lines is shown the index finger resting inthe arcuate surface of the upper abutment of the handle and the thumb resting in the arcuate surface of the lower abutment while the handle is gripped in a manner to enable the user to conveniently and effectively brush certain areas of the teeth and massage certain areas of the gums in both the upper and lower arches.

' and/or stop means.

Fig. 5 is a side view of the brush and a portion of a conventional holder show n in section, the handle of the .brush being disposed' in a holder opening with the head of the brush and the bristles elevatedin an uprightposition above the surface o f the holder.`

In accordance with the invention use is made of an elementof any suitable material to provide a head I0 and ,a ha' die II in continuation with said head. The head has secured thereto cleaning or brushing means such as the bristles I2 shown.. The handle at its juncture I3 with the head has raised portions I4 and I5 integral therewith. These raised portions I4 and I5 are disposed on the back and bristle sides respectively. The portion I4 has a curved or arcuate surface I6 and the portion I5 has a curved or arcuate surface I'I.A The arcuate surfaces I6 and I1 merge into the relatively broad flatsurfaces ,of the handle and diverge in the direction of the head. The surface I6 is longer than the surface I1 and as a consequence the raised portionsF are offset with respect to each other or spaced axially with respect Y to the longitudinal axis of the handle.

The raised portions hereinabove described thicken the handle at two places and constitute guides as well as anti-slip means, abutments The arcuate surface in each of these raised portions, respectively constitutes a more natural resting place for the inner surface of the index nger and/or thumb thereby permitting a more natural and rmer grip upon the brush. In this connection the positions i4 and I5 serve as abutments and as guides and yas rests for the index finger and thumb interchangeably and prevent such fingers from slipping forward while resting naturally within the respective arcuate surfaces and thereby enabling the user to obtain a more naturaland rmer grip upon the handle so that the brush may be Fig. 4 is a view similar to Fig. 3 but showing the index finger resting in the arcuate surface of Athe lower abutment of the handle andthe thumb resting in the upper abutment of the handle while the handle is gripped in a manner lto enable the user to conveniently and effectively brush the remaining areas of the teeth and massage the remaining areas of the gums in both the upper and lower arches.

guided and manipulated in any position for the convenient and effectualrbrushing of the teeth and massaging of the gums.

Furthermore, when the brush is not in use it may be arranged on a suitable holder in such `position with relation thereto that the bristles will be held elevated as shown for instance in Fig. 5. In this figure a portion of a holder is designated I8, and said portion has an opening I9 therein in which the handle is disposed. This brings the arcuate surfaces I6 and I'I in contact with the opposite walls of the opening by virtue of which the brush is retained upright with the bristles standing entirely away from any part of completely, and will the l'iolder. Consequently the bristles will not rest in, or come in contact with, any matter which may have been accumulated on the holder; the

bristles when wet may drain more quickly and i or upper surface of said handle orlstle-carrying-head than the the bottom or lowersurface said raised portions Vserving the purposes specied.

2, in a tooth brush, .an element providing a bristle-head and a handle in continuation of said bristle-head, said handle having'at its juncture With said bristle-head a raised portion with an arcuate surface both on the'upper and lower surfaces of said handle merging into the at surface portions thereof and said raised portions being oiset with respect to each other axially of the longitudinal axis of the handle to serve as abutments for the purposes specied..
