Wilhe m HILARION MORAN, OF FALL ,RIVER, MASSACHUSETTS.

MAGAZINE TOOTH-BRUSH.

I Application filed July 23, 1910. Serial No. 573,389.

To all whom it may concern:

Be it known that I HILARION MORAN, a citizen of the United states of America, residin at Fall River, in the county of Bristol and tate of Massachusetts, have invented new and useful Improvements in Magazine Tooth-Brushes, of which the following is a specification.

This invention relates to magazine toothbrushes, and the object of the invention is to rovide a handle of, reservoir form and a ollower operating in the reservoir and constructed toeject the paste in predetermined quantities.

In the drawing, forming a-portion of this specification and in which like numerals of reference indicate similar parts in the several views :Figure 1 is .a longitudinal sec tion through my improved brush. Fig. 2' is a side. elevation of the brush showing .the

'. closure in its applied position. Fig. 3 is a detail sectional elevation of a slightly modified form of' screw. g

The brush comprises a reservoir 1 which is of hollow cylindrical form. At one end the reservoir is provided with a head 2' which is formed with an interiorly threaded boss 3 to receive the correspondingly threaded stem 40f the brush-head 5; The brush-head has secured thereto the bristles 6, and as illustrated, the said head is formed to provide a feed passage 7 which opens at one enddirectly into the forward end of the reservoir 1. At the opposite end the passage opens onto a revolubly mounted valve 8 which is mounted in the passage 9 in the.

head. The valve is in form of a hollow tubular-like member having an opening 10 therein at one side. The valve is provided with a manipulating knob 11 which may be operated manually to cause the opening 10 to aline with the feed passage so as to open communication between the bristles ofthe brush-head and the reservoir. The reservoir 1 may be made of glass or transparent material so that the operator or user ofthearticle can readily learn the correct position of the follower 12. The .-follower 12 is of disk-form preferably, to conform to the transverse curvature of the reservoir and its peripheral edge is provided with a checking ring 13 to insure discharge of the paste. The follower is provided with a longitudinally extending threaded bore 14 through which a feed screw 15 extends. The feed screw has its outer end formed to pro I vide an unthreaded portion 16 which ex- Specification of Letters Patent. Patented J une 20, 1911. f

tends through the opening 17 in the removable. closure 18. The portion 16 is of a length sufficient to permit slight sliding movement of the screw and the follower. The screw is provided with an inner stop 19 and an outer stop 20, the latter being designed to engage the closure 18 to limit the inward sliding movement of the screw. The I stop 19 is designed to'engage the closure to limit the outward sliding movement of the stem.

From the construction of the device de- I scribed it will be seen. that the operator can .revolve the screw .15 to-cause the follower to move directly against the paste or cleaning material and considering the stopv 19 to be positioned against the closure 18 it will be seen that when pressure is exerted against the stop 20 .to move the same against the closure 18 a predetermined charge of paste a will be discharged from the reservoir. For

the purpose of regulating the amount of paste to be discharged the outer extremity of the portion 16' isthreaded, as shown at 21 and the stop 20 is formed to provide an interiorl threaded bore 22.

A ci osure 23 is designedto fit over the brush and to be engaged with the reservoir 1 as clearly shown inFig. 2 'of the drawing.

This closure has formed therein a series of perforations 24 so as to provide ventilation to the brush and to allow the evaporation of the substance which may remain moist on the bristles.

In the modified form of my invention shown in Fig. 3, the screw 15 is provided with the inner stop 19 and an outer stop 20'. The stop 20 .is somewhat similar to the stop 20 in the preferred form of the invention,

the difference being in that it is integrally formed with the screw. The device in the a modified form is substantially the same with other respects as that described in the preferred form. The screw is provided with I the unthreaded portion 16 which is located between the sto I claim 1.
