IMPROVED IM- PLEMENTS FOR DISTRIBUTING OR APPLYING POWDER
Year: 1858

page_text: LETTERS PATENT to Philibert Dumont, of Southwark Square, Boro', in
the County of Surrey, Gentleman, for the Invention of "IMPROVED IM-
PLEMENTS FOR DISTRIBUTING OR APPLYING POWDER."
Sealed the 7th December 1858, and dated the 9th June 1858.
PROVISIONAL SPECIFICATION left by the said Philibert Dumont at the
Office of the Commissioners of Patents, with his Petition, on the 9th June
1858.
I, PHILIBERT DUMONT, of Southwark Square, Boro', in the County of Surrey,
Gentleman, do hereby declare the nature of the said Invention for "IMPROVED
IMPLEMENTS FOR DISTRIBUTING OR APPLYING POWDER," to be as follows:-
My improved implements for distributing or applying powder are principally
for the distribution of powder to destroy vermin and insects, but may also be
used for various purposes. For this purpose I employ, by preference, an
india-rubber ball of such substance, that it has at all times a tendency to
distend; to this ball I apply a small tube or other suitable jet for distributing
the powder; the powder is introduced into the ball by a slit cut in the
side, or it may be other opening with a suitable cap or closuro, the powder
being inserted in the ball. By pressing and releasing the opposite sides of
the ball with the finger and thumb, the powder will be ejected at the
tube, or jet orifice, which is at the same time] directed to the part to which
the powder is to be applied. If a slit is formed in the ball for the introduction

page_text: of the powder, the thumb or finger must be placed thereon, to close it in
using the distributor, as described. Instead of the slit, the tube jet may be
fitted, so as to remove for the introduction of the powder..
For some purposes I fit a handle to the ball instead of the tube; and
according to the purpose intended I form a number of small holes in the ball
in that part opposite to such handle; or the holes may be in that part of the
ball immediately around the handle, or they may be around the extreme
circumference, assuming the handle to be in the line of the axis of the ball.
In using this implement with the handle, which may be of greater or less
length, according to the purpose for which it is to be used, the perforated
part of the ball may be dabbed on the part where the powder is required to
be applied, or it may be shaken or jerked suddenly, to cause the powder to
be ejected and distributed or applied, as desired.
Instead of india-rubber, gutta percha, leather, or other material may be
used for the ball, provided it has sufficient elasticity to keep the ball or powder
receptacle always distended, as described.
Instead of being a ball, also, it may be of any other form suitable for the
purpose.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Philibert Dumont in the Great Seal Patent Office on the
9th December 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PHILIBERT
DUMONT, of Southwark Square, Boro', in the County of Surrey, Gentleman,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of June, in the year of our Lord One
thousand eight hundred and fifty-eight, in the twenty-first year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto I, the said
Philibert Dumont, Her special licence, that I, the said Philibert Dumont, my
executors, administrators, and assigns, or such others as I,. the said Philibert
Dumont, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during tlie
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and: Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVED IMPLEMENTS FOR DIS-
TRIBUTING OR APPLYING POWDER," upon the condition (amongst others) that I,

page_text: the said Philibert Dumont, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and scals, should par-
ticularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months next and
inmediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Philibert Dumont, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, reference being bad to the Sheet of Drawings hereunto annexed,
and to the letters and figures marked thereon, that is to say:-
My improved implements for distributing or applying powder, are principally
for the distribution of powder to destroy vermin and insects; but may also be
used for various other purposes. For this purpose I employ an india-rubber
ball of such substance that it bas at all times a tendency to distend; to
this ball I apply a small tube or other suitable jet for distributing the powder.
The powder is introduced into the ball through a suitable opening with a
suitable cap or closure, or it may be closed by the tube orifice. The powder
having been inserted in the ball, by pressing and releasing the opposite sides
of the ball with the finger and thumb, the powder will be ejected at the tube
or jet orifice, which is at the same time directed to the part to which the powder
is to be applied. The jet is so fitted to the ball as to be readily removed for
the introduction of the powder.
For some purposes I fit a handle to the ball instead of the tube, and
according to the purpose intended, I form a number of small holes in the ball
on the side opposite to such handle, or the holes may be in that part
immediately around the handle, or they may be round the extreme cir-
cumference, assuming the handle to be in the line of the axis of the ball.
In using this instrument with the handle, which may be of greater or less
length, according to the purpose for which it is to be used, the perforated
part of the ball may be dabbed on the part where the powder is required to bo
applied, or it may be shaken or jerked suddenly to cause the powder to be
ejected and distributed, or applied, as desired.
Instead of india-rubber, gutta percha, leather, or other material may be
used for the ball, providing it has sufficient elasticity to keep the ball or
powder receptacle always distended, as described.
Instead of being a ball, also, it may be of any other form suitable for the
Durpose.

page_text: DESCRIPTION, OF DRAWINGS.
Fig. 1 represents an india-rubber ball, as for the purpose of and according
to my Invention; Fig. 2; a section; and Fig. 3, a plan of the same; it is
simply a thick vulcanized india-rubber ball,.a, a, having a hole in which I
insert a short tube b, b, this tube having shoulders c, c, between which the s
edges of the hole are gripped; the ball being highly elastic the hole therein
expands to receive the tube b; the tube b is removed occasionally for the
purpose of introducing the powder to be used with the ball.
Fig. 4 represents a modification of the foregoing, in which a handlod is
secured to the ball a in the same manner as the tube b before mentioned. In
this modification, of which Fig. 5 is an under side plan, I form numerous
perforations, as seen, from which the powder may be dusted as required.
Fig. 6 is a side view of the third modification, which differs from the last
merely in the position of the perforations, as seen. In order to introduce the
powder into these balls, I simply remove the tube or the handle d, and
expand the opening by means of a pair of spring tongs, somewhat like
sugar tongs, when, by means of a small funnel or other appliance, it is easily
effected.
Having described the nature of my Invention, and the manner of performing
the same, I declare. that what I claim as my Invention, to be protected by the
heréin-before in part recited Letters Patent, is, the application of india-rubber
or other resilient material, in balls or other suitable forms, for the purposes
and as herein-before described.
In witness whereof, I, the said Philibert Dumont, have hereunto set
my band and seal, this Eighth day of December, in the year of
our Lord One thousand eight hundred and fifty-eight.
