1 Claim. 1

The invention sufficiently described in the following specification that those versed in its art may understand its purposes, its functions and its mode of construction and manufacture, is also shown in the accompanying drawings which illustrate at least one form thereof, has for a primary object to provide a tooth brush adjustable relative to its handle.

Another object of the invention is to provide a tooth brush which may be rotatably adjusted on its handle.

A further object of this invention is to provide a tooth brush means whereby the brush may be quickly released from its handle but at the same time securely and rigidly held thereto.

A still further object of the invention is to provide a tooth brush handle so formed as to rigidly hold a detachable brush and to quickly release the same for replacement.

Other features and advantages will become more readily apparent from the following description and the accompanying illustrative drawings in which:

Figure l is a plan view of the invention,

Figure 2 is a perspective view-of a brush detached from the handle,

Figure 3 is a sectional view taken on line 33 of Figure 1, greatly enlarged,

Figure 4 is a side elevational view of the invention,

Figure 5 is a detailed plan view of Figure 3, and

Figure 6 is a view similar to Figure 1 showing parts in adjusted position for releasing the brush.

While one embodiment of the invention is illustrated in the above referred to drawings, it is to be understood that they are merely for the purpose of illustration and that various changes in construction may be resorted to in the course of manufacture in order that the invention may be utilized to the best advantage according to circumstances which may arise, Without in any way departing from the spirit and intention of the device which is to be limited only in accordance with the appended claim. And while there is stated the primary field of utility of the invention it remains obvious that it may be employed in any other capacity wherein it may be found applicable.

In the accompanying drawings, and in the following specification, the same reference characters are used to designate the same parts and elements throughout and in which 10 has reference to the complete invention which consists of a tooth brush ll upon the head l2 of which is a fixed polysided button 14, adapted to be held rigidly within an open ring I5, having a similarly formed inner surface l6. From the ends I! and ill of said ring I6 extend outwardly flaring arms l9 and 20, the outer extremities 2! and 22 of which are embedded in the furcations 23 and 24 of the bifurcated end 25 of a plastic or other tooth brush handle 26.

Slidably mounted upon the arms [9 and 20 is a ferrule 27 of less width than the normal spread of said arm ends 2! and 22, whereby when the ferrule is drawn upon the terminals of the said furcations they together with said ends 2| and 22 will be drawn together which action will draw the ends I! and 18 of the ring I5 tightly together to bind the ring upon the button I 4, which will hold the brush rigidly connected to the brush handle. However, upon sliding the ferrule down to the ring to release the furcations 23 and 24 allowing them to spread with the arms l9 and 20 and the Width of the ferrule being greater than the neck portion 28 of the ring the same due to its resiliency will also spread open enough to permit either the rotation of the brush rela- 'tive to the handle for adjustment, or for removal when worn out.

As clearly appears from the above specification the brush H (preferably shorter than the common tooth brush) may be adjusted to any angle of various angles to suit the individual user thereof and may be so adjusted that the bristles 29 may be moved vertically within the crevices between teeth to thoroughly cleanse the teeth, which cannot be readily done with the ordinary tooth brush.

From the foregoing specification it will become apparent that the invention disclosed will adequately accomplish the functions for which it has been designed and in an economical manner and that its simplicity, accuracy and ease of operation are such as to provide a relatively inexpensive device considering what it will accomplish and that it will find an important place in the art to which it appertains when once placed on the market.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Changes in shape, siz and rearrangement of details and parts such as come within the pur- 3 4 view of the invention claimed may be resorted to, adjacent each other to thereby lock said ring on in actual practice, if desired. said lug.
