unl'rsn stares SAMUEL DOSKOW, F NEW YORK, N. Y.

TOOTHBRUSHI Application filed January 27, 1928. Serial No. 249,953.

My invention` relates to improvements in brushes, and the same has for its object more particularly to provide a simple, eicient, and inexpensive tooth brush or other similar device in which the brush body is formed separately from the handle part, and in which the brush body may be readiiy secured to, Vor detached from its handle portion when it is desired to remove or renew the same.

i0 Further, said invention has for its object to provide a device of the character' specified in which the parts "thereof are readily locked together and released by imparting a quick longitudinal movement to the locking means therefor upon the rotation of said locking means. 4

Further, said invention has for its object to provide a device of the character specified in which the members or jaws for engaging the brush head or back are pivotally connected vat their inner ends to the handle, and in which a tubular locking member disposed upon the end of said handle may be quickly projected beyondtheend of said handle by imparting a slight rotary movement thereto and caused to engage said jaws for positively retaining the same in engagement withsaid brush back, and said brush back secured to the handle, and for locking said jaws against movement about the pivots thereof relative to said handle.

@ther objects will in part be obvious and in part be pointed out hereinafter.

To the attainment of the aforesaid objects and ends my invention consists in the novel details of construction, and in the combination, connection and arrangement of parts hereinafter more fully described and then pointed out in the claims. y

In the accompanying drawings showing an illustrative embodiment of the invention Figure 1 is a side view of the assembled device;

Fig. 2 is a plan thereof, showing the locking` member in retracted position;

Fig. 3 is a horizontal section thereof;

Fig. 4 is a perspective showing the parts in released and separated position; and

Fig. 5 an enlarged longitudinal vertical. section thereof.

In said drawings 10 designates the handle of the device, illustrated as a tooth brush, and 11 the brush head or bristle securing member. The head 11 comprises a back 12 in which the bristles 13 are secured or vanchored. Longitudinal grooves 14 are formed in the opposite edges of the back 12, which extend from the inner end thereof towards the outer end and terminate in recesses or depressions 15. The handle 10, whichis separate from the head or bristle member 11, has

a cylindrical portion 16 at one end thereof providedV with a longitudinal projection 17 to which the jaws or members 18, for engaging the back 12, are pivoted for movement about the vertical aires 19. The members 18 comprise two seini-cylindrical inner portions .20 which, when thesame engage each other, jointly correspond in cross section with that of the cylindrical portion 16. The outer por tions of said jaws 18 are received within the grooves 14 of the back 13 with the inwardly directed ends 22 thereof extending-into said recesses 15, whereby, when the parts are locked together. the same will serve to secure the member 11 to the handle 10 and hold the same against movement relatively to said handle 10. Y

The jaws 18 are held in closed position by locking means, such as an annular or tubular member 23 mounted upon the cylindrical portion 167 and movable longitudinally to project beyond the end of the handle and to embrace the semi-cylindrical parts or portions 20, and to be retracted to release the same to permit of the pivotal movement of the jaws 18. The locking means includes a relatively steep spiral groove or thread 24 formed in part upon one of the portions 20, as indicated at 24a, and in part upon the portion 16, as indicated at 24". A stud or projection 25 upon the annular member, 23 rides within said groove 24, whose ends serve as stops lim iting the travel of said stud 25.

In operation, the head or member 11 is placed between the jaws 18 with the outer portions and ends 22thereof disposed within the grooves 14 and recesses 15, respectively. A slight rotary movement then imparted to the member 23 will cause the same to be quickly moved beyond the end of the handle and embrace the portions 2O of the arms 18, and lock 'CTA the same in closed position; the rictional or' wedging engagement of the stud or pin with the groove 24 serving to eectively lock the parts together. It is to be noted that the member 23 serves to retain the arms or jaws 18 in engagement with the back l2, `and the bristle member 11 secured to the handle 10, and also serves to maintain said arms against movement'about the pivots 19 so that the 'en-v tire structure, when assembled and locked, is rigid. When it is desired to release the head or member 11,#or example, to replace the same when worn out'orV unfit Vfor further use by another, the member 23 is rotated in the reverse direction unt-il the pinj25` enters the portion 24h of said groove 24, thereby suii- Vciently retracting-the member 3 to permit of the free outward pivotal movement of the jaws-18150 release the brush member l1.

member movably vmounted upon the inner end of said. handle and adapted to engage said Vfirst named members for retaining the saine in engagement with said brush back and positively locking the said members Aagainst movement relative to said handle,and means :for Vimparting` a quick longitudinal movement to said tubular member upon ther rotation thereof including a steep spiral groove in one portion of the device .and a pin on another-portion riding in said groove, substantially as specified. j A r ,i v. 1

` 2. Adevice ofthecharacter described coin- Iprising a Vhandle having a cylindrical end portion, Vmembers for engaging a brush back c movably connected to said endportion and each having a semi-cylindrical portion at the connection thereof, said semi-cylindrical portions jointly corresponding in cross section Vwith that of said'cfylindrical end portion, a

tubular member rotatably mounted upon said cylindrical end portion, and means for imparting a quick longitudinal movement thereto upon the rotation thereof tocause the same to engage the adjacent portions of said first vnamed members for-retaining the same in engagement with the brush back 'and for locking the saine against Vmovement relative to Asaid (handle, substantially as specified.

3. A device of thechaiacter described coinprising a handle,` a pair of members adaptedv to engagea brush back and each movably connected at the inner ends thereof to .said handie, a locking member mounted upon the end responding in cross section with that'of said cylindrical handle portion, and :free outer portions adapted to'engage a brush back for securing the same to said handle, atubular member disposed upon said cylindrical end portion and adapted to project beyondvthe same to receive the inner portions of said jaws, a.y steep spiral groove formed in part upon the cylindrical end portion of saidhandle and in part upon one ofthe inner portions of said jaws, and avpin carried bysaid tubular member and adapted to travel in said groove uponthe rotation of said tubular member, substantially as specified.'

Signed at theV city of New York, in the borough of Manhattan, county of New York, and State of New York, this 6th day of April, one thousand nine hundred and twentyseven. Y
