I, WILLIAM COLE, of Fore Street, Ilfracombe, in the County of Devon, Ironmonger,
do hereby declare the nature of this invention to be as follows:-
-
My improved bellows or syringe is designed for ejecting insect powders, disinfectants,
and other powders or liquids.
It consists of a short tube or cylinder having one end tapered or conical and
terminating in a small hole through which the powder is ejected.
At the other end the cylinder is closed by an elastic cap of india-rubber resembling
the half of a hollow ball and having its convex side outwards. This cap is stretched
tightly over the open end of the tube so as to form an air tight flexible end to the
cylinder.
To keep this cap in place a hoop or ring is drawn tightly over the edge of the cap
and holds it firmly in the required position.
To eject the powder or liquid it is only necessary to press the Elastic india-rubber
cap when the pressure on the inside the cylinder drives out the contents.
This bellows can be made in various sizes and might be round oval or of any
preferred section and the india-rubber cap may be attached to the hoop or ring or if
preferred embedded therein or forming a part thereof.

An Improved Bellows or Syringe for Ejecting Powders or
Liquids.
I, WILLIAM COLE, of Fore Street Ilfracombe, in the County of Devon Ironmonger,
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 improved bellows or Syringe is designed for ejecting insect powder, disinfectants,
and other powders or liquids.
It consists of a short tube or cylinder having one end tapered or conical, and
terminating in a small hole or tube, through which the powder or fluid is ejected. If
preferred a small tap may be attached so that the orifice may be closed when not in
use, or a small cap may be provided for the purpose of excluding dust and preventing
tho escape of contents.
At its other end, the cylinder is closed by an elastic cap of india-rubber, resembling
the half of a hollow flexible ball, and having its convex side outwards. The edge of
this cap is stretched tightly over the open end of the tube so as to form an air-tight
flexible end to the cylinder. To keep this cap in place a hoop or ring is drawn tightly
over the edge of the cap and holds it firmly in the required position.
To cause the bellows to eject the powder or liquid it is only necessary to press the
elastic india-rubber cap with the thumb or finger when the pressure on the inside of
the cylinder drives out the contents.
The bellows is easily filled by removing the flexible cap. It can be made in various
sizes, and might be round, oval or of any preferred section, and the india-rubber cap
may be either loose or attached to the hoop or ring, or if preferred embedded therein
or forming a part thereof.
