follows:-
A bellows for using insect destroying powder so constructed in the interior with
a metal plate that the powder can be distributed anywhere necessary.
The metal plate consists of a round convex plate pierced with small holes and
connected with a metal tube extending from it into the nozzle of bellows. The

An Improvement in Powder Blowers.
I ENEA DECESARI of No. 5 Gresse Street Rathbone Place London W. Insect
Destroyer and Manufacturer 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 :-
A blower of bellows form such blower or bellows being constructed in the
interior with a perforated metal plate or dome and a metal tube extending from
such perforated metal plate or dome so that insect or other powder or powders can
be distributed anywhere necessary.
The perforated metal plate or dome consists of a round or other shaped plate of
a convex form perforated as aforesaid and connected with a metal tube or pipe
extending from such perforated metal plate or dome into the nozzle of the blower
or bellows.
The round or other shaped perforated plate or dome being fixed on the interior
side of the bottom board of the blower or bellows immediately below the hole in the
upper board of such blower or bellows which hole is used for the purpose of
inserting the insect or other powder or powders into the blower or bellows after
which insertion the said hole is securely closed by a removable cork or other
suitable stopper and by a slight pressure of the fingers and thumb of the manipulator
on the external sides of the two boards furthermost from the nozzle of the blower
or bellows the insect or other powder or powders is forced through the holes into
the perforated metal plate or dome which perforated metal plate or dome is as
aforesaid fixed on the interior of the bottom board of the blower or bellows and
the insect or other powder or powders passing through the metal tube or pipe
extending from the said perforated metal plate or dome is expelled or ejected from
the nozzle of the said blower or bellows.
In the accompanying drawing Fig. 1 is a perspective view of a blower. Fig. 2
a side view in section and Fig. 3 a plan with the top board removed.

page_text: In the three Figures 1, 2 and 3 "a" is the hole through which is inserted the
insect or other powder or powders required to be distributed "6" being the per-
forated plate or dome, the perforations "c" which are for the purpose of allowing
the insect or other powder or powders to be forced through the metal plate or
dome "," "d" is the tube or pipe attached to plate "6" and extending into
nozzle "e "of the blower-"f" is the top board and "g" the bottom board and "h"
the springs of the said blower or bellows.
The action of the blower or bellows is as follows When it is required to
distribute insect or other powder or powders such powder is inserted into the
blower through the hole "a" after which the said hole is securely closed by means
of a cork or other suitable stopper (not shewn on drawing) The blower is then
held in one hand only of the operator and by a slight pressure of the fingers and
thumb the two boards "f" and "7" are brought together and the air thus com-
pressed forces the insect or other powder through the perforations "c" of the plate
or dome "" along the tube "d" and out of the nozzle "e."
The perfect and uniform distribution of the powder depending upon the amalga-
mation which takes place between the air and the insect or other powder or
powders when passing through the perforations "c" of the plate "b."
The springs "h" are for the purpose of returning the board "" of the blower
or bellows to its normal position after each depression of the said board by the
fingers and thumb of the operator.
The bellows may be used for the purpose of removing dust or any other
powdered rubbish resulting from the manufacture of any article or articles
sculptures or masons work and the like thus enabling the operator to have one
hand disengaged for the carrying out of his work whilst using the blower with the
other hand a slight pressure of the fingers and thumb on the two outer boards being
only necessary.
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 as follows.―
1. An improvement in blowers or bellows such as herein before described for
the purpose of distributing insect or other powder or powders to any place
necessary.
2. An improvement in blowers or bellows so constructed with springs such as
previously described to be manipulated with one hand only of the operator. The
bellows may be used for the purpose of removing dust or any other powdered
rubbish resulting from the manufacture of any article or articles sculptures and
masons work and the like thus enabling the operator to have one hand disengaged
for the carrying on of his work whilst using the blower with the other hand,
a slight pressure of the fingers and thumb on the two outer boards being only
necessary.
3. In a blower or bellows a convex plate or dome of any suitable metal or
material and of any suitable shape having perforations for the purpose of dis-
tributing insect or other powder or powders in or on any place necessary bereinbefore
described.
4. In a blower or bellows: The combination of a tube or pipe with the perforated
plate or dome extending from the said perforated plate or dome and passing into
the nozzle of the blower for the purpose of distributing insect or other powder or
powders herein before described.
