Specification of Letters Patent.

Application filed December 26, 1912. Serial No. 738,776;

To all 10.7mm it may concern. l Be it known that I, LAJOS PAP, a citizen l of the Kingdom of Hungary. and resident of Arad, Austria-Hungary, have invented certain new and useful Improvements in Tooth-Brushes, of which the following is a specification. I The present invention relates to improve ments in tooth brushes. and more particularly to that type which is provided With a l hollow handle that serves for the reception I of a tube, containing toothpaste or other semisolid dentifrice, the latter being adapt 5 ed to be fed or forced to the bristles of the brush. whenever it is intended to use the same. One of the objects of the. present inven- I tion is to provide means, whereby the outlet i in the paste containing tube is maintained l in proper alinement with a discharge nozzle in the back or body of the. brush, in order i that none of the tooth paste may escape into I the interior of the brush handle or body and subsequently harden th re. causing? difl (h-ulties in the insertion of fresh tub s. f With these and other objects. in View; which will more fully appear as the nature 2 of the invention better understood. the l same consists in the combination, arrange mentand construction of parts hereinafter fully described, pointed out in the appended claim and illustrated in the accompanying drawings, it being understood that many; changes may be made in the re and pr portion of the several parts and dermis con slruction within the scope of the :1 p'pcude l claim Without departing from th spirit or sacrificing any of the advantages of the inl vention.

One of the many possible embodiments of the invention is illustrated in the ac ompanying drawings. in which Figure l is a f-ltl0 ele'ation of a tooth brush constructed in uwfordance with the present invention: Fig. 2 is a longitmlinal sectitn taken through the tooth paste containing tube; and Fig. 3 is a transverse sec tion taken through the handle of the brush and the tooth paste tube situated therein.

Referring now to the drawings. the character "6 denotes the brush handle. provided with the usual back 0". into which bristles j i are inserted in any suitable manner. The l l t t l l I a of a piston i as needed, by grasping:

handle a is tubular in form, andcommunicates through a discharge nozzle [2 with the bristles. said discharge nozzle extending 1 substantially at right angles to the face of said back. and being made of rubber or other resilient material to prevent injury to the gums. In the inner face of the rear end of the handle is provided a recess 0. in which is adapted to be seated a. projection e of a paste containing tube a, when the latter is inserted into the handle. The projertion e. engaging the recess firmly holds the tube in the handle against longitudinal movement. The tube d so dimensioned that, when the projection e engages in the recess the outlet f in said tube is brought into registering position with the discharge nozzle 1). Rotation of the tube in the handle is prevented by flattening a portion of the wall of the handle, as clearly shown in Fig. 3 of the drawings. and in a similar manner haping the paste tube (5. Within the tube is dispo ed a screw-threaded spindle it, shut proi'ided upon its outer end with a knob o. and meshes with the screu threads z. in the form of a. nut. which is located within the tube and is formed to ((ll'ZQSf.)(')l1(l with the cross section of the tube. whereby, when the spindle h is rotated. the nut cannot turn, but compelled to advance longitudinally.

In use a portion of the contents of the paste tube may be forced into the bristles, the lmob between bomb and inger and turning the some, *ich imparts :1 correspond 1g: movement to the spimflle and advances the piston i, that presses against the body f the contents. partial turning of the spindle is usually suflicient to deliver a suflicient quantity for use at one time from the contents of the tube through the outlet f and the discharge ozzle 6 to the bristles. It is to be observed that the knob g is tiwdlv attached to the spindle i1, consequently the paste. tube with the feeding means. that s to say the piston, knob and spindle. form a unit that can be removed from and ifiil'ttll. as a Whole, into the tubular handle of the brush. Inasmuch as the paste cannot escape into the interior of the brush back or body, the handle will always remain clean and ready for the re- Peption of fresh tubes.

What I claim is rl said tube in said handle and thereby main 10 In a tooth brush. the combination With a l taining said outlet in registering position hollow handle provided with a discharge l with said discharge nozzle. nozzle leading to the bristles of a paste tube Signed at Budapest, Hungary, this. ltih located in said handle provided with an outi day of December A, D. 191-1 let in alinenient with said discharge nozzle, L U()?:- PAP. means for feeding the contents of said tube Witnesses:
