As the brush headissecured tothe handle solely by frictional engagement with the handie clamping member it will be noted that t my e r dily turnedand edill e ed'tb ariousposition's as clearly shown-in Fig,

,withontopeliating the adjusting nut 1 9. 7 In Fig. -6 Ihave shown a modified form of brush headin'which theclamping member 24 is dispensedwith, thestud 25 being formed integral with the back of thebrush head 20 and preferably of the same material, this form being consideredimportant as maybe imanufactured much more economically than the form first described. 7 V V V It is well understood thatapersonsteeth should be brushed in avertical direction towards and away from the gums. By pro-I viding a comparatively small brush that may be instantly adjusted at various angles with respect to the handle, a person may readily brush the teeth in such manner, and further 5 the interior surfaces may be readily reached for cleansing.

What I claim is: l. A toothbrush construction including a brush-head having an upstanding stud on the said brush-head, said handle having a hollow portion in the outer end thereof and a clamp,- ing mechanism slidably disposed in the hollow portion, said clamping mechanism being adapted to engage said stud, and rotatable means disposed on the handle and in threaded association with said-clamping mechanism foroperating the same to frictionally clamp the mechanism to the stud.

2, A tooth brush construction including a brush-head, an upstanding stud on the back of said brush-head, a handle provided with a slidable stud gripping element, and means including a rotatable member, for detachably constricting the element about the stud on said brush-head to frictionally clamp the handle to the stud.

3. A toothbrush construction including a brush-head, anupstanding stud on the back ofsaid brush-head, and a detachable handle provided with spring clamping arms slidably associated therewith, and rotatable means for relatively displacing said arms to grip the stud and hold the brush-head in adjusted relation with the handle.

4. A toothbrush comprising in combination, a back having an upstanding stud thereon, a handle having a hollow port-ion, means slidable, axially, substantially within the hollow portion of the handle, and a threaded element, rotatably engaging said means for detachably and frictionally' associating the means and stud to clamp the handle thereto.

5. A toothbrush comprising a back having an upstanding stud formed thereon and a handle detachably attached thereto, said handie provided with a tubular outer'end, the inner end of the tubular portion opening into a nut receiving aperture, a stud clamping member having a stud receiving opening in its outer end and a rearwardly extending slot leading from said opening, whereby the size of the studopening may be decreased in diameter, a threaded stud formed on the inner end ofsaid clamping member, and a nut disposed in the aperture of the clamping member and engaging said threaded stud.

6. A toothbrush construction including a brush-head, an upstanding stud on the back of said brush-head, a detachable handle provided with spring clamping arms, and having a hollow portion to receive saidarms, the "arms being movable axially, in said hollow portion, for engaging the stud to hold the brush-head in adjusted angular relation to the backthereof, and a handle pivotally engaging threaded means, rotatable relative to and re.-

cessed within the handle, to operate 'the clamping means and connect same with thehan l 8. A toothbrush construction including a brush-head, an upstanding stud on the back of said brush-head, a handle having a hollow portion in the outer end thereof, a clamping mechanism disposed substantially within the hollow of said handle, said clamping mechanism being adapted to. engage said stud, and means, rotatable relative to said handle, associated with said clamping mechanism for operating the same within said hollow portion to frictionally clamp. the mechanism to the stud and to connect said mechanism with the handle.

9 A toothbrush comprising a handle having' a tubular portion, a resilient element, slidable relative to and extending into the tubular portion of the handle; rotatable means for moving said resilient element, ax-. ially, relative to the handle; a brush-head, and means on said brush-head, frictionally and detachably embraced by said resilient cle ment whereby the brush-head and handle may be held in selective positions relative to each other.

10. A toothbrush comprising a brush-head; a handle having a hollow portion; a stud on said brush-head a variable tension clamp engaging the stud and extending into the'hollowportion; and means, associated with the handle and in rotatable relation thereto, for operating the clamp, whereby the brush-head and handle may be detachably connected and whereby selective and relative angular adjustment may be efiected between the brushhead and handle,

11. A toothbrush construction including a brush-head having an upstanding stud thereon, a stud clamp, a detachable handle substantially enclosing said clamp, and a member rotatable relative to the handle and in threaded engagement with the clamp.

12-. In a tooth brush holder, a handle having a socket therein; a clamping mechanism slidably disposed in the socket and rotatable means associated with said clamping mechanism adapted to operate the same to engage a brush member. v

13. A tooth brush holder comprising a handle provided with a tubular outer end, the inner end of the tube opening into a nut re- CQlVlIlgflPltLllfG; a brush clamping member having a brush receivingopeningin its outer end and a rearwardly extending slot leading from said opening, whereby the opening may be decreased in diameter; a threaded stud formed on the inner end of the clamping member; and a nut disposed in theaperture 5 and engaging said threaded stud.

In witness that I claim the foregoing I have hereunto subscribed my name this 30th day of July, 1925.R
