of the elongated casing and means is provided` for forcing the tablets into a chamber adjacent the bristles as they ,are used. Also, a valve or detent is provided within the elongated casing for allowing the passage oneat a time, thereby retaining the balance of the tablets within the handle portion of the casing.

The primary object of this invention is to provide a device of the above mentioned character in which. a supply of tooth paste or the like is carried in the handle of the tooth brush, whereby the Anecessity of using paste or cleaning material from a tube is dispensed with thereby providing a more sanitary Inan- L ner of cleaning teeth and it is necessary for each individual to provide his own brush and series of cleaning tablets.

A still further object of this invention, is to provide a device of the above mentioned .j character having comparatively few parts to become out of order and which may be cheaply and easily manufactured at a minimum cost. y

Other objects and advantages of the invention will become apparent during the course of the following description, forming a part of the specification, in which,

Figure l is a longitudinal top elevation of the invention illustrating the apertures in the top wall of the housing and showing the cap at one end of the casing and the bristles embedded in the opposite end of the casing; Figure l is a longitudinal cross-sectional view illustrating the manner in which the tablets or tooth paste are retained in the handle and the manner in which they are adapted to be projected into the dispensing chamber individually;

One end offthe rectangular'handle 6 is provided* -with a disk 8 having suitable threads for a cap or closure 9. As the handle- 6 is rectangular in cross section itis necessary to providerthe"disk"8'finrder'that the cap Y9 may be VscrewV threaded thereonhy a certain movement.'

In this manner, the

oblong detent 19 may be held in its closed po.-

sition, blocking the entire cross sectional area of the elongated'casing 6.

1 Also pivotally mounted in areduced portionl of the slot 18 `is a trip member 27 pivotally held in place asby meansA ofa pin 28. The

pin 28 passes through a bore 29 in the upper edgeof ythe trip 27 and also lhas its ends anchored in the edges of the'sl'ot 18. A'lexible element 30 has one of its ends embedded in the vsidewall of the detent 19, while its opposite end is curved ,andembedded in the top edge of the trip 27, whereby movement of the oblongdetentf'liwill simultaneously cause VleX-` in'gofthe flexible l'member 3 0 and; cause movement of the'trip27-or allowing the passage of` "one capsule 15 at a time.

The constructionf'illustrated"in Figure 13,"

includes 'an elongated casingl 5 similar toy the elongated casllgr 'handle 5 and the han;

After a tablet l5 has been projected into the chamber 1st the remaining cubicals are retained in the handle by means of the detent 19 whereby the operator may present the brush to a suitable water supply from a faucet whereby portions of the tablet 15 will be dissolved and fed to the bristles 12.

The operation of the device as illustrated in Figure 13 is somewhat similar to the operation of the device disclosed in Figures l to 12 inclusive with the exception that the tooth paste tablets l5 may be fed forwardly by means of the spring pressed follower 8 or there may be positively operated or projected forwardly into the chamber 6 where they may be acted upon by presenting the brusn 12 to a water supply whereby a portion of the tablet may be dissolved and fed through the opening 17 onto the bristles l2.

lt is to be understood that the forms of the invent-ion herewith shown and described are to be taken as the preferred examples of the same, and that various changes may be made therein without departing from th spirit and scope of tie invention as claimed.

1. A tooth brush of the character described, comprising an elongate-cl casing having apertures at one end thereof, tooth brush bristles mounted adjacent the apertures, a closure for the opposite end of the casing, means for feeding a series of individual tooth paste tablets to a position adjacent the apertured portion of the casing, and means for retarding the forward movement of the capsules whereby one tablet will be allowed to be moved into the compartment in close relation to the apertured portion of the casing at a time.

2. A tooth brush of the character described, comprising an elongated casing having apertures at one end thereof, a series of tooth brush bristles mounted in close relation to the apertures, a removable closure screw threaded on the opposite end of the casing, a coil spring mounted within the casing, a series of individual dentifrice tablets also mounted in the casing, and a pivoted detent mounted in the casing for preventing passage of more than one dentifrice tablet at a time into the apertured portion of the casing.

3. A tooth brush of the character described, comprising an elongated casing having apertures at one end thereof, a removable closure for the opposite end of the casing, a series of dentifrice tablets mounted in the elongated casing, means for feeding the tablets to the opposite portion of the casing and a pivoted detent mounted in the path of the dentifrice tablets.

4. In a brush, a casing having a mixing chamber and a reservoir for tablets of cleaning compound, a bristle element in communication with the mixing chamber, a valve between the chamber and reservoir and a stop actuated by the opening of the valve whereby a single tablet of cleaning compound is admitted into the mixing chamber.

5. The combination with a brush having a mixing chamber for an external liquid and a reservoir for internally carried tablets of cleaning compound, and a bristle element in communication with the mixing chamber, of means for admitting a single tablet of the cleansing compound into the mixing chamber including a valve between the reservoir and mixing chamber, and a stop raised and lowered by the opening and closing movement of the valve and extending into the reservoir for automatically arresting the passage of more than a single tablet of cleansing compound.

6. A brush comprising a reservoir for tablets of a cleansing compound and a saturation chamber with a bristle element in communication with the saturationv chamber, a valve separating the reservoir and chamber, means for opening and closing the valve and means attached to the valve for automatically limiting the feeding of the tablets of cleansing compound admitted to the saturation chamber upon each opening movement of the valve.

7. 1n a brush of the character described, a. hollow handle comprising a compartment for tablets of cleansing material and a mixing chamber with a bristle element in communication with the mixing chamber, a valve interposed between the compartment and chamber and a trip 'device in the compartment for engagement with the tablets of cleansing material and controlled in its operation by the valve to be disengaged from the tablets of cleansing material by operation of the valve to permit a single tablet of cleansing material to be moved into the mixing chamber.

8. A brush as recited in claim 7, characterized by a spring arm carried by the trip device and engaged with the valve.

9. In a tooth brush having an elongated handle, one end of which acts as a receptacle for dentifrice tablets and the other end acts as a mixing chamber for the dentifrice and a liquid, a valve dividing the receptacle and mixing chamber including a lift, a flap valve and al stop carried by the flap valve whereby the tablets are admitted into the mixing chamber in measured quantities.

ln testimony whereof I affix my signature.
