This invention relates to tooth brushes and the object of the invention is to provlde a tooth brush having a compartment handle for containing tooth paste and' arranged so that the tooth paste may be fed from the handle into the brush.
,Another lobject of the invention is to provide a tooth brush having a double compartment handle in which the handle may be re-` versed to allow the tooth paste to be utilized from either compartment.
A further obj ect of the invention is to provide a tooth brush havinga magazine handle portion for tooth paste and a brush portion including aplunger movable into the magazine portion to force the tooth paste through a duct in the brush portion into the bristles.
. These objects and the several novel features of the invention are hereinafter more fully described and claimed and the preferred form of construction by which these objects are lattained is shown in the accompanying drawings in which Fig. 1 is a section embodying our invention.
Fig. 2 is an enlarged view showing the brush end of the tooth brush.'v z, A
Fig. 3/is a section taken on line 3--3 of Fig. 2.
Fig. 4 is a section showing the connections of the tooth paste compartments.
d Fig. 5 is a view of the end of the tooth pastel uct.
Fig. 6 is a section through an alternative formof tooth brush. l
The tooth brush comprises a handle formed of two tubular com artments 1 and 2, shown in Figs. 1 and 4. ach compartment is provided with a closed end 3 having an aperture 4 therethrough and the compartments are connected together by a threaded ring 5 into which the ends 'of the compartment are threaded. Each compartment 1 and 2 is also lprovided with an externally threaded open end opposite the closed end 3. The open end of the compartment 1 is threaded into Aan internally threaded ring 6 and al member 7 is also threaded into the ring 6. A cap 8 is threaded onto the open end of the compartment 2 and is provided with a central threadthrough a. tooth brush 1929. serial No. 356,011. l
ed aperture which is closed by the liller plug 9. Thel brush end is made in two parts, a part 10 carrying thebristles and a part 11 which is provided with threads and is adapted to be threaded into the member 7. The 'g5 members'lO and 11 are connected together by means of a threadedsleeve 12 .which also con- -nects the conduits or ducts 13 and 140i the duct 13 opens through the end of the member "11 into the compartment 1 and the end of the member 11 is provided with a packing 15 in the annular channel 16 provided therefor and this packing ts the inner wall of the member 7. As shown in F ig. 2 the duct 14 leads through a member 17 over which a rubber cap 18 is secured and this cap 18 is provided with a slot 19 in the end through which the tooth paste may be discharged into the bristles 20 of the brush.
In order to lill the handle with tooth paste the compartment 2 is turned in relation to the compartment 1 to bring the apertures 4 into alignment as shown in Fig.,1. The plug 9 is then unthreaded from the cap 8 on the compartment 2 and the end of a tooth paste tube 30 .for use.
. To use the device the handle is held in one 'i hand while the tooth brush portion is rotated with the other hand to unthread the portion 11 from the member 7. t will be noted from Fig. 2 that the companion threads on the members 7 and 11 are similar to pipe threads so thata tight tit may be had at this point. At this time the tooth brush portion may be' pushed to the left of Fig. land the end lo of Ithe tooth brush and packing actsV as4 a piston to put the tooth paste under compres- 15 may be utilized for brushing the teeth. When all of the tooth aste in the compartment 1 has been utilized) the handle is removed by unthreading the compartment 1 from the threaded ring 6 and the handle is turned end for end. At this time the cap 8 is removed and the end 2 is threaded into the ring 6 while A the ca 8 with the plug 9 is threaded onto the end o the compartment 1. By this arrangement the tooth paste in the compartment 2 maybe utilizedl until the compartment 2 is em ty whereupon thevhandle may be refilled as fore by removing the plug 9 and turning the compartments to bring'the apertures 4 to alignment. The peripheries of the compartments 1 and 2 adjacent the closed ends 2 are preferably each provided with a mark or indication to indicate when the apertures 4 are in alignment.
A simpler form of the invention is shown in Fig. 6 in which a single compartment 21 is provided into the. end of which the handle member `11 is threaded. A cap 8 and a plug 9 are provided on the opposite end of thecompartment 21 and the brush end is made suiiiciently long so that it may be moved the entirelength of the compartment 21 for forcing the tooth paste into the brush bristles.
As will be noted from Fig. 3 by making the brush end 10 of the cross sectional form shown, suiiicient space is provided therein for the duct 14 without interfering with 'the bristles 20 and at the same time the'end of the brush is not bulky or ungainly in form. As the slot 19 in the cap 18 is closed except when the tooth paste is forced therefrom the brush may be readily washed out without'getting water into the cap 18 or duct 14 and foreign I,matter cannot lreadily enterthe said cap.
This cap is preferably made of soft rubber-so as notto in]ure the teeth when they are being brushed.
From the foregoing description it becomes evident that the device is very simple and eflicient in operation, will not easily get out of order, will ca'rry a considerable supply of tooth paste 'and prcvides a device which accom lishes the objects described.
aving thus full described our invention, its utility and mode lof operafion, what we 18 onto the bristles'of the brush.
