Improvements in the Working of Gas Engines.
1 JOSEPH WILKINSON of Blue Hall, Ingleton in the County of York,
Photographer do hereby declare the nature of this invention to be as follows:-
My improvement relates to the working of the old style of gas engines such as
the Bischoff and other similar makes. These are defective in not making constant.
and regular revolutions which causes serious inconvenience.
I propose to remedy this by causing ordinary coal gas as now used, to pass
through a vapour of benzoline, gassoline, or any other similar volatile oil or liquid
contained in a cylinder which is filled with cotton, prior to being delivered into the
bag which supplies the engine for explosive purposes. The mixture of gases passes
from the bag to the engine at various parts according to the construction and the
result is that it improves the combustive properties of the ordinary gas, much
more readily igniting thereby providing a regular and constant motion of the
engine.
I also claim to apply this invention to the lighting of the front part of the
engine.
Hitherto engines have been lighted both at back and front. This improvement
can be adapted to both parts.
Dated this Ninth day of January 1892.

COMPLETE SPECIFICATION.
Improvements in the Working of Gas Engines.
I JOSEPH WILKINSON of Blue Hall, Ingleton in the County of York
Photographer 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 improvement relates to the working of the old style of gas engines such as
the Bisschop and other similar makes. These are defective in not making constant
and regular revolutions which causes serious inconvenience.
I propose to remedy these defects by causing ordinary coal gas as now used to
pass through a vapour of benzoline, gassoline or any other similar volatile oil or
liquid contained in a cylinder, which is filled with cotton, prior to being delivered
into the bag which supplies the engine for explosive purposes.
In order to carry out my said invention of mixing coal gas with the vapour as
before described, I devise various arrangements in addition to the cylinder before
mentioned which are essential to the proper attainments of the objects named but
are subservient to the main principle of my said invention.
I first construct a cylinder, which may be made of any kind of metallic substance
or any other suitable material, which is to contain the benzoline or other vapour.
Into this cylinder I fix a wire work frame over and into which is placed cotton
wool or some similar absorbent to take up the liquid in, which latter condition the
benzoline is first supplied. The cotton wool is also placed in the lower portion of
the cylinder for the same purpose of holding the liquid. Part of this cylinder will
therefore contain liquid and the remainder vapour, by reason of the volatile
character of whatever oil or liquid may be used. This cylinder may be supplied
from any ordinary cistern or receptacle, at the bottom or it may be put in at the
Price 8d.1

page_text: top or in any other manner so as to thoroughly saturate the whole of the absorbent
material. Connected with the cylinder is a pipe called the inlet gas pipe which
supplies ordinary coal gas which passes into the same and becomes mixed with the
vapour therein contained. From the other side of the cylinder there passes a pipe
to the front of the engine which supplies the 'said mixture to the engine for
explosive purposes. I find that the use of this new gas or mixture requires the
atmospheric air supplied to the engine, to be-properly regulated, and. in order that
this may be done for the purpose of using the said mixture obtained in the manner,
named I fix at the top of the cylinder an india rubber bladder, fitted in, a wire-
work or metal case for protection, which is fixed uninflated to the cylinder. Con-
nected with this bladder is a horizontal rod, which may be made of any length to
suit any particular engine, made of iron or other suitable metal fixed to the same
by means of a union and, attached to this is a spring to keep the rod to the
bladder; this works upon a cog and is connected with another rod placed at a right
angle and working upon the same cog. The distant end of the upright rod is fixed
to the sliding door or doors, which are perforated, which supplies the common air:
to the engine. There is fixed to the door a screw or screws so as to easily adjust
the position of the door, and instead of altering the rods.
This contrivance-cylinder and appendenges-(which I call a dynamo) being
fixed to an engine will work in the manner following:-
The cylinder becomes charged with a supply of benzoline which passes into a
vapour as before stated and this is renewed from time to time from the liquid.
contained in the absorbent material; secondly, a supply of coal gas which becomes
diffused through the vapour and the mixture is then prepared for passing to the
engine. The bladder fixed at the top, in a state of vacuity, also becomes inflated
by the mixture. By turning on a tap fixed on-the exit pipe leading from cylinder the
gas passes to, the cylinder of engine and it becomes ignited which at once causes
an explosion, immediately setting the engine in motion. Now to keep up a suitable
supply of atmospheric air to engine the bladder fixed at the top of cylinder, when
full, presses against the horizontal rod forcing out the same, which simultaneously
draws away the upright rod thus raising or lowering the sliding door; the bladder
being released, the rods pass back to their previous position.
The bladder is partially influenced by the explosion, but it is chiefly acted on
according to the pressure of the coal gas supply and accordingly works 'the'
apparatus for regulating the common air inlet; when it enlarges a greater quantity
of air is admitted. This opening and closing of the air inlet may also be obtained
by pneumatic or similar arrangements.

Letter A represents a cylinder containing benzoline partly in liquid marked N
and partly in a state of vapour; B is a supply cistern for A; C is coal gas supply
pipe connected to cylinder; D is a pipe which conveys the improved gas to the

page_text: style but any makes which are defective in their regular working or it may be
constructed in the making of gas engines of any kind, or description to answer the
purposes named.
The use of this improvement will remedy the defects of irregular explosions
and consequent imperfect revolutions and will also give the impulse at the proper
time. It will be more economical and it will be found that complete explosions of
gases which will take place by the use of my invention, will keep the engine in a
cleaner condition, doing away with the deposit which now takes place and obstructs
the workings.
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
1. The construction of a cylinder to contain the vapour of benzoline, gassoline,
or any similar volatile oil or liquid in the manner named and with the various
contrivances thereto attached to fix to gas engines for the purposes herein described
and as illustrated by the said drawings.
2. The incorporating of the said contrivances in the original making of any kind
of gas engines in the same manner and for the same purposes as herein described.
