PROVISIONAL SPECIFICATION.
Improvements in Boxes for Tooth Powders.
GEORGE BARKER, Hampton-on-Thames, Middlesex, Chemist. I do hereby
declare the nature of this invention to be as follows:-
.
The invention consists of a tin, canister or box, having two chambers; the upper
one A to contain the powder, and the lower one B containing a spring slide C,
covering D holes punctured in the bottom of the upper chamber. This spring
slide also has holes punctured, and at distances equal to those in the bottom of the
upper chamber, and on being pushed back by the tooth-brush, which is admitted
by an orifice E in the side of the chamber B, brings the holes in the slide directly
under those in the bottom of chamber A; allowing the powder to fall on the
tooth-brush, which has been admitted bristles upwards. The brush, been taken
away, allows the slide to return, covering the holes D in the bottom of the powder-
chamber by the interspaces of the slide.

Improvements in Boxes for Tooth Powders.
1, GEORGE BARKER, of Hampton-on-Thames, in the County of Middlesex,
Chemist, 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 :—
My invention has for its object an improved receptacle for tooth powder of such
construction that when the tooth brush held with the bristles upwards, is pressed
into an opening. formed therein a sufficiency of the powder will be caused to fall
thereon.
In carrying my invention into practical effect I use a box of circular or other
desirable shape and material but preferably of tin, and divided horizontally into
two chambers. The upper of these chambers is for the reception of the powder
and is preferably so shaped as to guide said powder towards three or any other
suitable number of holes formed in the bottom thereof. Beneath these perforations
a spring actuated slide is arranged to move in suitable guides in lower chamber
opposite an opening formed in the side thereof. The upper portion of this slide is
perforated with similar holes to those in the bottom of the upper chamber so
arranged that they do not lie immediately under those in the bottom of the upper
compartment when the slide occupies its normal position, but by pressing the tooth
brush, bristles upward, through the opening in the side of the lower chamber and
pressing the slide back against the pressure of the spring the holes in the slide and
bottom of the upper chamber may be brought to coincide, and a sufficiency of the
powder allowed to fall on to the brush.
And in order that my invention may be more fully understood and carried into
practice I will now proceed to describe the same with reference to the accompanying
drawings, of which
Fig. 1 is a sectional elevation and Fig. 2 a sectional plan on line x-y Fig. 1 of
a tooth powder box constructed according to my invention.
The box a is divided horizontally into two compartments bc the upper one 6 of

guide this towards three or any other desirable number of perforations d in the
bottom thereof. Beneath these perforations the slide e normally held in position
shown by spring is arranged to move in suitable guides in the lower chamber c
opposite an opening g formed in the side thereof. The upper portion of slide.e has
similar holes formed therein to those in the bottom of the upper compartment but
so arranged that when the slide is in the position shown they do not lie immediately
under said holes in the bottom of the upper compartment but may be brought into
a position to do so by pressing the slide back with the tooth brush which has been
previously inserted in the opening g bristles upwards, and so cause a sufficient
quantity of the powder to fall on said brush.
'
When found more desirable the spring slide e may be operated by a button or
the like instead of by the tooth brush as above described.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
A receptacle for tooth powder constructed and operated substantially as described
-and illustrated in the accompanying drawing.
