Description

July 26, 1938. A. BAULER 2,124,647
TOOTH BRUSH Filed April 24, 1937 www Mmm Patented July 26, 1938 UNITED STATES PAT-ENT OFFICE TOOTH BRUSH George A. Bauler, Minneapolis, Minn.
Application April 24, 1937, Serial No. 138,795
1 Claim.
This invention relates tol tooth brushes of a which presents a substantially unbroken eiIectype whichis particularly suited for use when traveling.
One of the objects of my invention is to provide a tooth brush construction which is conveniently made so that it can be carried in the pocket and also to provide a brush which has greater eiliciency than the type of tooth brush in general use today. It is a brush so constructed that no matter how it is held in the hand it is always in position for brushing the teeth, since there is no top or bottom or right or wrong side of the brushing element itself.
Another object of the invention is to provide a brushing head which can be changed from one position to the other relative to the handle so that certain parts of the mouth can be more easily reached.
These and other objects and advantages will more fully appear from the following description made in connection with the accompanying drawing, wherein like reference characters refer to the same or similar parts throughout the views, and, in which:
Fig, 1 is a plan view with part yof the handle and protective cap broken away;
Fig. 2 is a plan view with the cap removed and the head in one of its positions;
Fig. 3 is a plan view showing the head attached to the handle in a dierent position, and
Fig. 4 is a section taken on the line 4 4 of Fig. 3.
In the drawing, I have shown ahandle 6 which is preferably of uniform cylindrical shape throughout most ofits iength. The top portion of the handle is tapered as at .6 and the extreme tip of the handle is 'provided with a threaded portion 1.'
The brush head includes a relatively long nar# row bristle-supporting base 8 to which a plurality of radiating bristles 9 are secured in any desired manner. The bristle-supporting element l can be made of a plastic material with thesecured to the handle in either of the positionsA shown in the drawing, and it will be found that by changing the position of the head relative to the handle, it'will be much'easier to cleanv certain of the .teeth which are diiilcult to reach with an ordinary brush. It should also be noted that, because of the bristles` radiating from the base in the manner shown, there is provided a brush head4 which is cylindricalin shape and tive cleaning area throughout the entire brush head. In the conventional tooth brush, the bris tles are secured to one side of a base element and the brush must be held in one particular position with respect to the'l teeth. It will be readily seen, however, that with my construction the brush head and handle are so formed that the brush is always in position for use and need not be twisted or otherwise manipulated to bring the bristles into proper contact with the teeth.
Toward the upper portion of the handle, I have provided a threaded area I2 ,for securing the cap I3 which is adapted to lit over the brush head when the head is secured in the positions shown in Figs. l and 2. This protective cap will keep the brush clean and will also permit placing of the brush in a suitcase or in the pockets of the user immediately after the brush has been used and before it has dried. A clip Id may be provided to secure the article in the pocket and Ventilating 4openings I5 are also preferred.
'I'he main portion of the handle 5 is hollow to provide a chamber Ii for a small tube of tooth paste or for a supply of tooth powder. -The lower `end oi the hollow handle is open and is provided the mouth, since the main portion of the handle is relatively large to provide sulcient space for the powder chamber i6.
From the foregoing, it will be seen that I have provided a simply constructed self-contained tooth cleaning device which may be clipped in the pocket of the user when not being used. 'I'he shape of the brush head and its adaptability to diiierent positions with respect to the handle provide a device of greater emciency without going into a complicated structure.
- It will, of course. be understood that various changes may be made in the form. details, ar-
throughout substantially its entire cylindrical surface area to provide a substantially unbroken .l cylindrical brushing surface. and said brush head being detachably secured to the end of said handle at right angles thereto, whereby surfaces of the teeth canbe reachedwithportions ot said bristles always lying in brushing position.
