PROVISIONAL SPECIFICATION.
An Attachment to a Syringe for the Production of Smoke, Primarily
for Destroying Insects and the like on Plants.
I, PERCY PARNALL GIEVE 164 Nelson Road, Hornsey London N. Clerk,
do hereby declare the nature of this invention to be as follows:-
:
A cylinder of brass, wood, pipeclay or a combination of these or other suitable
materials the said cylinder being closed at one end with the exception of one or
more small holes, the open end of the cylinder being fitted with a perforated lid or
arranged so as to fit the rose of an ordinary garden syringe. The exterior of the
cylinder to be shaped to fit the interior of the end of au ordinary garden syringe,
into which it may either sink flush with the end (in which case the syringe roso
could be screwed in place) or left projecting from the end of the syringe. Or the
closed end of the cylinder may be left with a projecting rim or collar to push or
screw onto the exterior of the end of an ordinary syringe.
The said cylinder to be of convenient size & shape to contain tobacco, tobacco.
paper, spices, or other substances that may be found suitable.

The cylinder, being secured in position at the end of the syringe, is filled with
the tobacco &c., which, after ignition, is consumed by the familiar in & out
motion of the syringe piston, the smoke issuing through the perforations of the
cylinder lid or by a separate aperture; as found in practice most desirable.

1 PERCY PARNALL GIEVE of 164 Nelson Road, Hornsey, London, N. Clerk
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 cylinder or receptacle of brass, wood, pipe-clay, or a combination of these or-
other suitable materials, the said cylinder being closed at one end with the.
exception of one or more small holes. This cylinder is fastened into the interior
of the end, or on to the exterior of the end of a syringe, similar in construction to.
one in ordinary use for gardening purposes, the closed end of the cylinder being.
towards the handle of the syringe. A perforated lid or cap having numerous small
holes, which may conveniently be made to converge into one central aperture, is
then made to push or screw, or to otherwise fasten on to the open end of the
cylinder. The full size drawing shews a cylinder fixed to a specially manufactured
syringe, the cylinder A being sunk into the interior of its end, a non-conductor of
heat being placed at B, with the lid or cap C in place, such lid or cap having
numerous perforations in the plate D converging to a small central aperture E, the
cap or lid being shewn as pushing or sliding on to the end of the syringe.
Where
the cylinder attachment is fitted to an already existing syringe the rose or nozzle.

page_text: usually accompanying an ordinary garden syringe can then be fitted on to the open
end of the cylinder, thereby taking the place of the perforated lid before mentioned.
The cylinder being secured in position at the end of the syringe, is filled with
tobacco paper, spices or other similar substance, which is ignited. The perforated
lid or syringe rose is then fitted on, and the ordinary in and out motion of the
syringe piston causes a stream of smoke to issue from the syringe.
The novelty of the invention consists in the attachment to a syringe of a cylinder
designed and suitable to contain material, the combustion of which by fire in
conjunction with and by means of the in and out motion of the syringe, shall cause
a jet or spray of smoke to issue, and in the utilization of such alternate motion of
the syringe piston to produce and direct the emission of smoke from burning
material.
A non-conductor of heat, such as asbestos or wood may be placed at the junction
or between the cylinder and the syringe to prevent the latter becoming hot.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is ;
1. The exclusive right to manufacture and sell, or cause to be manufactured or
sold, a syringe having at one end a cylinder or receptacle designed to contain
tobacco and the like in a state of ignition.
2. The right to manufacture and supply such a cylinder by itself for the purpose
of affixing to a syringe of ordinary manufacture.
Dated this 10th day of April 1895.
