This invention appertains tonew and useful improvements in tooth brushes and more particularly to a tooth brush of the self con-y tained tooth paste supply type.

e An important object ci the invention is to provide a tooth brush wherein the handle thereof is adapted to contain a supply of tooth pa ste, and which is provided Awith means whereby the toothpaste can be dispensed. very readily.

Another important object of the invention is to provide a tooth brush of the character stated.. capable of beingmanufactured at low cost. I

Thess and other'important objects and advantages of the invention will become apparent 'to the reader of the following specification and claims.

ln the drawings Y Figure 1 represents a side elevational view of t le novel brush structure.

Fig. 2U represents a longitudinal sectional view through the brush.

Fig. 3 represents a side elevational view Fig. 4c represents a. cross sectional view taken substantially on the line. 4.--4 of Fig. 1. Fig. 5 xpresents a side elevational view of the no e with the brush removed.

Fig. 6 represents a top plan view of the nozzle with the brush removed.

Fig. 7 represents a top plan view of the brush removed from the nozzle. A

Fig. 8 represents a longitudinal sectional Referring to the drawings wherein like I numerals designate like parts, it can be seen that numeral 5 represents a barrel, provided with threads at one end for receiving the cap 6, .which cap is provided with a central opening 'for' recei the shank 7 of the tube 8, which is located within the barrel 5. The shank 7 extends a substantial distance beyondvthe cap 6 Iand has the knurled collar 9 secured thereon by the pin 10.

The inner end of the tube v8 is provided with a nut 11 through which' the internally and externally three ed sleeve 12 is feedahle when the nut 11 is rotated. The sleeve 12 receives the externally threaded .rc-d 13 which lthe barrel 5 opposite to the cap projects from the follower 14, the follower being provided with a circumferential packing 15 wiping the inner side of the cartridge 16, which is shown in detail iii-Fig. 8.

A stop member 17 is provided on the end of 55 the sleeve 12 adjacent the cap 6. The endof v 6 is threaded for engagement into the end portion 18 of the nozzle structure 19 which tapers outwardly toward its free end. The under side 00 of the nozzle 19 is reduced and provided with a longitudinally extending channel at each side thereof. The nozzle is also provided adjacent its outer end with a lip 21 projecting in substantially parallel relation to the portion provided with the channel 20. It can also be seen, that the, area betweenthe lip 21 and the groovedv portion is provided with an obstruction 22 and by referring to Fig. 2 it can bev seen that the passageway 23 in the nozzle is diverted upwardly as at 24 at this point.

As is shown in Fig. 4, the outer end portion of the nozzle is basined out as at 25. The brush includes a block 26 provided with a substantially V-shaped trough 27 therein and the block has openings 28 therein extending downwardly from the trough through the bottom of the block, so that paste in the trough can be forced downwardly against the bristles 29.y

` The block 26 at Vthe upper portion of the trough 27 is providedwith arib 30 which engages into the grooves 20 of the nozzle 19, securing the block 26 to the nozzle after the reduced portion 31 thereof has been engaged above the lip 21 of the nozzle.

The cartridge. for containing a. supply of paste comprises the tube 16 in which the 90 paste 32 is packed. This tube 'is provided with a readily movable plate 33 while the opposite end is provided with a. stopperv 34 which can be readily removed.

vThis is a manner in w in the cartridge form, and obviously by removing the stopper 34, the same can be inserted into the barrel 5. It can now be seen that when the collar 9 is rotated, the consequent rotation of the nut 11 will feed the sleeve 12 10 ch the paste is lsold 95 forwardly so that the follower-14 will exertitself against the paste in the cartridge 16.-

Obviously, when ,the sleeve 12 has been Y fed to the extent that the stop 17 binds against the nutll, thenut and sleeve will rotate tother. This will rsult in the feeding of t e rod 17, further extending the follower uns tilx substantially allof the paste has been dis- -pensed from the cartridge tube 16.

^ 1 0 While the foregoingciicationsets forth the invention in spec' c terms, it is to be understood that numerous changes in the shape, size and materials may be rorted to without departing from the spi-rit and scope Y of the invention as claimed hereinafter.

Having thus described my invention, what I claim as new is:

1. A tooth' brush comprising Aa barrel, a tube rotatably mounted within the. barrel, 2Q means at one end of the barrel for rotating the tube,- an internally threaded nut on the tube, an externally and internally threaded sleeve feedable by the said nut, a follower, a rod extending from the follower and provided with threads to engage with the internal y threads ofthe sleeve, and a brush head a the opposite end `of ithe said barrel. 2. -A tooth-brush comprising an elongated body, a reduced extension at one end of the v body, a short lip at the same end of the-body' in substantiall parallel relation `to the ex'- tension, a brus head including a back,'said, back being engageable against the extension with one .end thereof between the extension and the li sald'back being pel"-y forated and provid with a basin on itsinner side, said extension rovided at;

its inner side with a groove, an a .chamber in the body 4communicating with the ve 40 and basin when the back 1s assembl with the body.'l

In testimony whereofI axmy u ture. HOLLIE L. TB Irl:
