PROVISIONAL SPECIFICATION.
A Vessel with Delivery Mechanism for Powders and other
Substances.
I, CHARLES EBENEZER CHALLIS of No. 30 Navarino Road, Hackney London
N.E. Machinist, do hereby declare the nature of this invention to be as follows:-
The invention consists of a vessel with a mechanical device for delivering the
contents in small quantities by a simple movement; the primary object being to
avoid the wasteful and objectionable practise of dipping a wet tooth brush into an
often deliquescent powder, but it is also useful for delivering other powders pills etc.,
in small quantities, and for other purposes.
The mechanism herein specified admits of certain modifications and adaptations
according to the general and decorative design it is intended to adopt, the purpose
for which it is employed, and whether is desirable to actuate it by a pull, push,
rotary or partly rotary motion.
The apparatus constructed as a vase for tooth powder etc. consists of a receptacle
for the powder, with a partition or collar in or on its lower part; the collar has an
opening cut through it and this is stopped by a plug or slide which is supported in
a sort of funnel that directs the powder on to the brush; depending from the plug or
funnel is a rod or stirrup which is sustained in position by a flat, bow or other
suitable spring contained within the base or stand.
The tooth brush being inserted in the stirrup and pressed downwards the plug is
withdrawn and a quantity of powder is drawn down and falls through the funnel on
to the brush; the pressure being then removed the spring returns the plug into
position.
When constructed in a bottle form the vessel has an opening at the top with a
cap fitting in or on the neck and terminating in a nozzle; within the cap are two
horizontal partitions, between which a slide is placed with a finger piece projecting
beyond, the whole being held in position by a spring; ports are cut through the
upper partition into the nozzle and through the lower partition into the vessel, but
not opposite each other; a chamber cut in the slide being opposite the port in lower
partition when at rest, and opposite the upper port when pressed home.
To obtain a delivery the bottle is reversed, a quantity of powder then falls
through the port into the slide chamber, and on the slide being pressed in the
chamber is brought opposite the nozzle port and the powder falls out.
In either of the above forms the plug may be cylindrical with chambers cut in it,
these becoming filled with powder from the vessel and then being emptied on to the
brush as the plug is revolved.

A Vessel with Delivery Mechanism for Powders and other
Substances.
I, CHARLES EBENEZER CHALLIS of 30 Navarino Road, Hackney, London
N.E., Machinist, 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:—
In the accompanying drawings
Figures 1 and 2 are section and elevation respectively of the first described vase,

page_text: A is the receptacle for powder; B is the base or stand; C is the collar attached to
the bulb and screwed or otherwise connected to the base; M is the exit for powder
stopped by the plug D; E are claws to ensure the powder falling; F is the funnel
to direct the powder on to the brush; FF shows part of the passage around the
plug D; GG are the sides of stirrup; H is the dome shaped push piece upon
which the tooth brush or its equivalent is pressed; I, I are wings or guides sliding
in grooves in the base; K is a helical spring; L is a plate supporting the spring.
When the push piece is pressed by the back of tooth brush, or otherwise, the
plug D is withdrawn from the hole M and a quantity of powder is drawn down by
the claws E, the powder being directed on to the brush by the funnel piece, on
removing the pressure the plug and connected parts are returned by the spring.
In Figure 3, A is the bulb or bottle shaped receptacle for powder; B is the cap
and nozzle; C is the screwed collar attached to the neck of the bulb; D is the
slide; M is the port in the cap opposite the chamber O in the slide; N. is the
passage through the nozzle; K is the spring. To operate: the vessel is reversed
and a portion of the contents falls through the port M into the chamber O, the
slide is then pushed in (compressing the spring K) until the chamber is opposite
the passage N through which the charge falls, the slide is returned by the
spring.
Figure 4 shows a vessel from which delivery is effected by a rocking or swinging
movement, A is the chamber for powder &c.; B is the base; C is the collar; D is
the end view of a cylindrical valve or plug with chambers D1 and D' therein,
mounted upon the pivot P; DD is a stirrup depending from D. On the stirrup
being swung in either direction the chamber D₁ (or D³) is brought through the
crown of the base and the contents dropped, or directed as required.
Modifications are made in certain cases to meet special requirements, such as the
delivery of pills, sweets &c. &c. without departing from the main features herein
indicated.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
Vessels with delivery mechanism for powders and other substances, substantially
as set forth, and shown in Figures 1, 2, 3 and 4.
