To @Z whom t may concern.:

Be it known that we, JOHN S. SANGER, residing at Orange, and RODERICK M. SANGER, residing at East Orange, Essex county, New Jersey, citizens of the United States, have invented certain new and useful Improvements in Apparatus for Applying Tooth-Powder, fully described and represented -in the following specification and the aecompanyin g drawings, forming a part of the same.

The object of this invention is to furnish a convenient means of preserving the tooth powder, and applying it to the brush; and it may also alford a means of sustaining the brush when not in use. Y

The invention consists primarily of a back piece adapted to hang upon a wall, a tooth powder receptacle projected from the front side of such back piece with an outlet above the bottom of the receptacle, a movable screen for discharging the powder, and a tray projected from the back piece below the outlet and held removably thereon.

The invention will be understood by reference to the annexed drawings, in which- Figure 1 is a front elevation of the entire apparatus. Fig. 2 is a partial sectional view of the same on line 2, 2, in Fig. 1. Fig. 3 is a plan in section on line 3, 3, in Fig. 1, showing an alternative construction for the screen. Fig. e is an edge view of the screen shown in Fig. 3. Fig. 5 is a side elevation of the apparatus with tooth brushes supported in the clips and upon the guide, the handles of the brushes being broken. Fig. 6 is a vertical section of the lower part of the apparatuson line 6, 6, in Fig. 3.

A is the back piece which is formed of a sheet met-al plate with beaded border and hollow back. The border is drawn with diagonal lines to represent an imitation of a cable pattern. The back piece carries upon. its front side the sheet metal receptacle B which may be attached to the back piece by lugs b (shown in Figs. 2 and 6) extended through openings in the back piece and clinched behind the saine. The receptacle has a cover Gwhich is jointed to the back piece byhinge g and pin g located within the hollow back. The cover is tted tightly to a flange B upon the top of the receptacle. The outlet E in the bottom of the receptacle is formed with upturned flanges e, as shown in Fig. 6, which support a discharge platef havinga discharge opening f A screen h or h is fitted movably upon the plate above such opening to prevent the discharge of the powder until desired, and such screen may be formed with holes e', as shown in Fig. 2, the opening f", as shown in Fig. 3. The screen h is pivoted at one end, and has a handie j projected through the side of the receptacle at the opposite end, to vibrate it thereby; as the tooth powder packs in such manner that it falls through the holes t' only when the screen is in motion.

Where a perforated screen is merely vibrated over the opening in the discharge plate, the opening may be made as large as the outlet at whichthe brush is applied; but where the screen is withdrawn from the opening, as in Fig. 3, the opening is made quite narrow, as shown at h', to restrict the discharge in the desired degree.

The screen h is tted between ribs f2 upon the platef, as shown in Fig. 6, and is formed upon its upper side at the inner end with several pins kadapted to loosen the powder when the screen is slid endwise, as shown in Fig. 3, thus loosening the powder temporarily and securing a sufficient discharge of the powder through the opening ff.

Theback piece A is formed, below the receptacle, with a loop Z which is pressed forward from the metal of the holder, and the tray O is shown with a foot m bent downwardly to it within such loop, thus securing the tray detachably upon the holder below the outlet E. Y

The holder is provided near one end of the outlet E with clips forming a guide o to hold the tooth brush handle p, as shown in Figs. 1 and 5, so as to support the bristles of the brush beneath the outlet E.

The anges e which support the discharge plate f a little distance above the bottom of the receptacle, are preferably converged inward, as shown in Figs. 2 and 6, and the chamber or passage between the discharge plate and the outlet is thus expanded outwardly.

or be arranged to uncoverl IOO The outlet is made a little smaller than the usual area of the bristles upon the tooth brush, to wholly prevent the bristles from crowding into the chamber or passage.

The elevation of the discharge plate above the bottom of the receptacle not only forms a closed chamber for the diffusion of the powder between the discharge plate and the iiange, but it thus prevents the bristles of the brush from coming in contact with the plate. l

As it is common to wet the brush before applying the powder, the water upon the brush if allowed to touch the discharge plate, would cause the powder to stick in the discharge opening and thus render the apparatus inoperative. The construction therefore provides effectively for holding the wet bristles aty a suitable distance below the discharge plate, while it prevents the loss of powder which would result if it were not confined in a closed chamber.

A sufficient supply of powder can be discharged through an opening much smaller than the surface of the bristles, and the flaring form of the outlet produced by the inwardly converging flanges e thus permits the scattering or diffusion of the powder over the bristles as it is discharged through the openingf by the movement of the screen. Such scattering being Ieffected in a diffusion chamber, the loss or waste of powder is almost wholly prevented.

Any surplus powder is caught by the tray O, and as the tray is held detachably by thev foot m, it may be kreadily removed from the holder to throw out the powder or restore it to the receptacle.

Spring clips D are shown projected at one side of the receptacle to engage the neck of the tooth brush handle, and thus support the tooth brush when not in use. The whole device furnishes a convenient means of storing and applying the powder and of sustaining the tooth brush in readiness for use.

To close the outlet tightly, so as to prevent the leakage of powder in transporting the receptacle, we provide a swinging gate n of form similar to the ,screen h, pivoting the same to the bottom of the receptacle at one end of the outlet, and fixing a catch n tothe receptacle and to the opposite end of the outlet, to press the gate closely against the outlet. The gate is shown open in Fig. l, and,y closed in Fig. 6, to prevent the discharge of the powder. The gate is shown as a thin flat plate, and the catch isforined as a sloping lug adapted to crowd the gate upward against its seat upon the receptacle, when4 the4 edge' of the gate is forced beneath the lug. The

gate thus affords a cheap and effective means of closing the outlet tightly.

From the above description it will be seen that the diffusion chamber is a very important feature of an apparatusfor applying powder economically to a moistened tooth brush. To form such chamber in asuitable manner, the outlet should correspond to the shape of the tooth brush and be made a little smaller than the area of the bristles, to prevent their admission to the chamber. In such construction, the movable screen forms in reality the top of the didusion chamber, as it affords," when not in use, a partition between such chamber and the powder in the receptacle above.

Having thus set forth the nature of the invention, what is claimed herein is l. As a new article of manufacture, the sheet `metal back piece A provided upon one side with the receptacle B having the outlet in the bottom with movable screen, and the back piece having the loop Z below such outlet, and the trayC adapted to projectv from the back piece, and provided with the foot m bent downwardly and fitted removably within Lthe loop, asand for the purpose set forth.

back piece A provided upon one side with the receptacle B having the outlet in the bottom with movable screen, and the tray C projected from the back piece and attached removably to the same below the outlet, and

the spring clips o projected from the baclr piece below the outlet andarranged to support the tooth brush against the outlet when applying the powder, substantially as kset forth.

3. As a new article of manufacture, the tooth powder receptacle B having in the bottom the outlet E corresponding in shape to' the outline of the tooth brush bristles, and provided with a diffusion chamber above such outlet, a discharge plate having a discharge opening and fixed at the top of the diffusion chamber, with a screen fitted movably to the plate, the whole arranged and operated to provide, with the brush applied to the outlet, a closed space between the screen and brush, within which the powder is scattered upon its discharge from the receptacle, substantially as herein set forth.
