PROVISIONAL SPECIFICATION.
Apparatus for Applying Tooth Powder.
We, RODERICK MCLEAN SANGER, of East Orange, County of Essex, State of
New Jersey, U.S.A. Dental Surgeon, and JOHN SCOTT SANGER, of Orange,
County of Essex, State of New Jersey, U.S.A. Dental Surgeon, do hereby declare
the nature of said invention for Apparatus for Applying Tooth Powder, to be as
follows:-
The object of this invention is to furnish a convenient means for preserving
the tooth powder and applying a charge thereof to the moistened tooth brush.
The invention consists primarily of a receptacle having an outlet in the bottom
to which the moistened bristles of the brush are applied, with a discharge plate
and movable screen sustained within the receptacle a suitable distance above such
outlet to form a diffusion chamber in which the powder is scattered as it falls upon
the brush.
The arrangement of the discharge plate and movable screen above the outlet
forms a closed chamber for the diffusion of the powder, and also keeps the
moistened bristles from contact with either the screen or the discharge plate,
and thus prevents the clogging of the opening. The outlet is preferably made
a little smaller than the usual area of the bristles upon a tooth brush, so that
the bristles close the outlet during the application of the powder, the loss or waste
of which is thus wholly prevented. To preserve any powder that may be dropped
from the brush in removing it from the outlet, a removable tray is fixed beneath
the outlet.
In one form of the construction, the receptacle is attached to a back plate by
which it may be hung upon a wall, and the side of the receptacle is furnished with
clips to support the tooth brush when not in use. Clips are also provided to hold
the bristles of the brush against the outlet, and the tray is attached removably to
the back piece by fitting a bent flange upon the edge of the tray to a loop projected
from the back piece.
In another form of the invention, the receptacle is mounted upon a stand formed
of wire, a band of which encircles the body of the receptacle and is provided with
four downwardly and outwardly projecting legs, which are connected near the
botten by wire ties.
In such construction the tray is supported removably upon the ties.
The outlet is, if desired, closed by a movable gate, the end of which is arranged
to engage a sloping lug which presses it firmly against the outlet, thus preventing
the loss of powder in transportation.
The discharge plate may be made with a large opening, and the screen consist
of a movable plate with numerous perforations, or the discharge plate may be
provided with one or two long slots, and the screen be formed of an imperforate
Hat strip fitted to move longitudinally over the slot upon the top of the discharge
plate and extended outward through the wall of the receptacle.
In such case, a pin is projected from the upper side of the screen plate over each
slot, to loosen the powder over the slot, as the screen is retracted; thus securing
the required discharge of the powder.

page_text: The body of the receptacle, including the cover, is of rectangular shape,
with all the corners heavily rounded, thus presenting an approximately oval
appearance.
The receptacle mounted upon the wire frame is especially adapted for use upon
the toilet table; while the receptacle with the back piece is adapted to hang upon
the wall.

Apparatus for Applying Tooth Powder.
We, RODERICK MCLEAN SANGER, residing at Orange Street, in the Town of
East Orange, County of Essex, State of New Jersey, U.S.A. Dental Surgeon, and
JOHN SCOTT SANGER, residing at 343 Main Street, in the City of Orange,
County of Essex, State of New Jersey, U.S.A. Dental Surgeon, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The object of this invention is to furnish a convenient means for preserving the
tooth powder and applying a charge thereof to the moistened tooth brush.
The invention consists primarily of a receptacle having an outlet in the bottom
to which the moistened bristles of the brush are applied, with a discharge plate
and movable screen sustained within the receptacle a suitable distance above such
outlet to form a diffusion chamber in which the powder is scattered as it falls upon
the brush.
The arrangement of the discharge plate and movable screen above the outlet
formis a closed chamber for the diffusion of the powder, and also keeps the
moistened bristles from contact with either the screen or the discharge plate,
and thus prevents the clogging of the opening. The outlet is preferably made
a little smaller than the usual area of the bristles upon a tooth brush, so that
the bristles close the outlet during the application of the powder, the loss or waste
of which is thus wholly prevented. To preserve any powder that may be dropped
from the brush in removing it from the outlet, a removable tray is fixed beneath
the outlet.
Several forms of the invention are shown in the annexed drawing, in which
Fig. 1 is a front elevation of the apparatus formed with a back plate; Fig. 2 is a
partial sectional view of the same on line 2, 2, in Fig. 1; Fig. 3 is a side elevation
of the same apparatus with the head of a tooth brush supported by the clips in two
positions; Fig. 4 is a vertical section of the lower part of the apparatus on line 4, 4,
in Fig. 5, which is a sectional plan (like Fig. 2) including the tray, and showing
an alternative construction for the screen; Fig. 6 is an edge view of the screen
shown in Fig. 5; and Fig. 7 is a perspective elevation of the apparatus with legs
to set upon a toilet table.
In the form shown in Figs. 1 to 5 inclusive, the receptacle A is attached to a
back plate by which it may be hung upon a wall, and the side of the receptacle
is furnished with clips C to support the tooth brush D when not in use. Clips C
are also provided to hold the bristles of the brush against the outlet E, and the
tray F is attached removably to the back piece by fitting a bent flange upon the
edge of the tray to a loop m projected from the back piece.
A cover A is fitted tightly to a flange upon the top of the receptacle.
The outlet E in the bottom of the receptacie is preferably formed with upturned

page_text: flanges e, as shown in Fig. 4, which support a discharge plate f having a discharge
opening f¹.
In Figs. 1 to 4 inclusive, the screen is fitted movably upon the plate / above
such opening, and such screen is pivoted at one end and has a handle projected
through the side of the receptacle to vibrate it thereby, as the tooth powder packs
in such manner it can only be discharged through the holes in the screen by
moving the latter.
In Figs. 5 and 6, the screen is shown as a flat bar fitted between ribs 2 upon
the plate f, and is formed without perforations and provided upon its upper side
with several pins k, adapted to loosen the powder when the screen is slid end wise,
as shown in Fig. 4. The pins then loosen the powder and discharge a portion of
the same through a longitudinal slot f'.
+
The device is used with either form of discharge plate, by moistening the
bristles and inserting the handle in the clips C¹ to hold the bristles against the
outlet the discharge plate being then agitated to deliver the powder upon
the bristles.
The elevation of the discharge plate fabove the bottom of the receptacle, not
only forms a closed chamber between the plate and the brush to prevent the
seattering of the powder, but prevents the wet bristles of the brush from coming in
contact with the plate.
Any surplus powder is caught by the tray C and as the tray is held detachably
by the foot or flange 1, it may be readily removed from the back plate to throw out
the powder or restore it to the receptacle.
To close the outlet tightly and prevent the leakage of powder in transporting
the receptacle, we provide, as shown in Figs. 1 and 4, a swinging gaten, 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 catel n' to the receptacle at the opposite end
of the outlet, to press the gate closely against the outlet.
The gate is shown opened in Fig. 1 to apply the brush to the outlet; the
brush being indicated in dotted lines, and the gate is shown closed in Fig. 4
ready for transportation.
In Fig. 7, the receptacle A is mounted upon a stand formed of wire, a band a
encircling the body of the receptacle, and provided with four downwardly and
outwardly projecting legs a', which are connected near the bottom by wire ties a².
The gate is represented similar to that shown in Figs. 5 and 6, and vibrated
by a hand-lever b. The tray F is supported removably upon the ties. This design
of apparatus is adapted to set upon the toilet table, and the body of the receptacle
including the cover, although of rectangular shape, has all the corners heavily
rounded, thus obtaining an approximately rounded appearance.
Having thus set forth the nature of the invention, what we claim herein is :
1. The tooth powder receptacle A having back piece or legs to support the
same, and provided with the outlet E having the movable screen, and the tray F
supported detachably below the outlet, as and for the purpose set forth.
2. The tooth powder receptacle 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 the 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 a brush applied to the
outlet, a closed space between the brush and screen, within which the powder is
scattered, upon its discharge from the receptacle, substantially as set forth.
3. The tooth powder receptacle A, baving in the bottom the outlet E provided
with a discharge plate having the slot f, the screen fitted to move longi-
tudinally over the slot upon the upper side of the discharge plate, and a pin or
projection upon the upper side of the screen, substantially as herein set forth.
4. The tooth powder receptacle, having in the bottom the outlet E provided with a
discharge plate having a discharge opening with screen fitted movably thereto,

page_text: and the swinging gate n pivoted to the receptacle below the outlet, and the
lug n for securing the gate, substantially as herein set forth.
