We, JOHN GILMORE, of the Vicarage, West Norwood in the County of Surrey,
Clerk in Holy Orders, JOHN FARQUHAR GILMORE, of the same place, Merchant, and
WILLIAM RICHARD CLARK, of 3 Danby Street, Peckham, in the County of Surrey,
Mechanician, do hereby declare the nature of this invention to be as follows:-
Our invention relates to a device for the generation of Steam, more notably when
employed for warming and cooking purposes, and it is designed to effect such
generation in a speedy and economical manner, and without excessive expenditure of
heating materials, approximately the whole of the heat generated by the flame being
utilised, under the most favourable circumstances for such generation of Steam.
Our invention consists essentially of a Cone with a valve at its apex. This valve
is either a weighted valve, such for instance as a ball resting on a seating and limited
as to its movements by a cage, or a spring pressed valve.
This device is placed bottom downwards in any vessel where rapid generation of
steam is desired. When heat is applied to the Vessel, the steam pressure against the
weighted valve drives the water from underneath the cone to an amount equivalent to
the weight or resistance of the valve. A thin film of water is thus left at the bottom
of the vessel exposed to the effects of the heat, and a rapid generation of steam is
effected, which escapes through the valve whenever the weight or resistance of the
steam is overcome.
This device in its simplest form, as before specified, may be combined with a cage
to support any article required to be steamed in cooking, such as potatoes.
Again it may be combined with a permanent vessel equivalent in form to the cone,
and this again contained within a suitable casing, a space being left all round the
outside of the vessel, and the walls being prolonged downwards, so as to form
deflectors for the heat of the lamp or other heating device. The bottom of the outer
casing is either loose or fixed, and is provided with circumferential perforations, so
that an induced draught may be created, which shall carry the heat around the
prolonged walls and up the sides between the vessel and the casing, so that the full
xtent of the heating power is utilised, a suitable chimney being provided at the top.-

page_text: The steam is led by any suitable pipe from the top of the vessel (which is closed) for
any purpose which it may be destined, such as the heating of Greenhouses etc. This
pipe may, after being carried round the heating system, be brought back to a feed
tank, and the condensed steam thus re-utilised. The feed tank may be in communi-
cation with a vessel to keep same fed by gravity, or the feed may be effected by a
force pump.
Again, where our device is required in a portable form, we may utilise the form
last described; but we carry the steam pipe from the vessel into a closed cowl, into
which the heated steam is delivered, and which is thus brought up to a high degree of
temperature. This closed cowl is formed with a perforated shed at its periphery, and
the condensed steam is shed into the feed tank, which conveniently surrounds the
casing.
Again we may utilize our device for the rapid heating of water for baths, boilers
and such like, in which case a tap is inserted in the Cone.
We have specified the foregoing as likely adaptations of our device; but we do not
propose to confine ourselves to same, should we find it useful in other situations where
the rapid generation of Steam is desired; and we may find it necessary to construct
our valve of much greater resistance than for the purposes hereinbefore specified.
Dated this 29th day of September 1886.

Improvements in Steam Generating Apparatus.
JOHN GILMORE of the Vicarage West Norwood, in the County of Surrey, Clerk in
Holy Orders, JOHN FARQUHAR GILMORE of the same place, Merchant, and WILLIAM
RICHARD CLARK of 3 Danby Street Peckham, in the County Surrey Mechanician,
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:
Our invention relates to a device for the generation of Steam, more notably when
employed for warming and cooking purposes, and it is designed to effect such
generation in a speedy and economical manner, and without excessive expenditure of
beating materials, approximately the whole of the heat generated by the flame being
utilized under the most favourable circumstances for such generation of steam.
In order that our invention may be the better understood, we now proceed to
describe the same in relation to the drawings hereunto annexed, reference being had
to the letters and figures marked thereon-Like letters refer to like parts throughout
the drawings.
Figure. I. Is a general elevation of the device of the steam generator, as to be
placed inside a pot, boiler, or other such chamber.
Figure 2. is the top view of the said Steam Generator.
Figure 3. Is the side elevation of the Steam Generator, as placed in a pot or other
vessel, or chamber, permanent and equivalent in form to the steam generator, and
this again contained within another suitable vessel or casing.
Figure 4. Is our device with a closed cowl applied over the chimney, with a
perforated shed at its periphery, with a steam pipe leading into it, and with the vessel
in which it is placed as in figure. 3.
Our Invention consists essentially of a hollow cone A fig. I. open at the bottom,
and with a valve B at its apex K. This valve is either a weighted valve, as a ball
resting on a seating, and limited in its movement by a cage L, or by a spring
pressed valve.
The cone A is made hollow, and is open at the bottom, and is placed bottom
downwards in any vessel where rapid generation of steam is required.
When heat is applied to the vessel, as soon as steam is generated in the inside of the
cone A, the steam pressure against the valve B, drives the water from the interior of
the cone A, to an amount equivalent to the weight or resistance of the valve. B.
A thin film of water is thus left at the bottom of the vessel, within the bottom edge,
or periphery, of the cone A and is thus exposed to the effect of the heat, and a rapid
generation of steam is effected, when the weight or resistance of the valve. B is
overcome the steam escapes through the valve B in a state superheated in proportion
to the resistance it has overcome, and the thin film of water at the bottom of the
cone A is constantly replaced by water pouring under the edge of the cone A, from
the outside as the film is evaporated.
Again this device A, may be permanently combined with a vessel F, F, F fig. 11I
of an equivalent form to the cone A and this again contained within a suitable vessel,
or casing, G. I. I. D. D. fig. III. outside the vessel F. F. F. A space S. S. is left
passing through a tank I. I to act as a chimney and to assist in raising the temperature
of the water in the tank 1. I; and the outer walls of the space S. S. are prolonged
downwards to form deflectors for the heat of the lamp, or other heating device.
In the bottom D. D. of the outer casing G. I. I. D. D. is an opening O for the
p

page_text: introduction of the lamp, or other heating device, or the whole bottom D. D. may be
removed and the whole surface of the bottom of the vessel F. F. F. exposed to direct
contact with the flame.
When the bottom D. D of the outer casing is not removed it is provided with
perforations at its circumference E. E. so that an induced current is created, which will
quicken the combustion and draw the unexpended heat up the spaces S. S. to the
chimney G which is provided at the top of the vessel, F FI
The steam generated in cone A, and escaping through valve B into the upper
portion of the vessel F. F. F. may be led by a pipe H, or by more pipes than one,
from the said upper portion of the vessel F. F. F. for any purpose for which it may
be destined, for instance, as into different compartments of cooking stoves, into
steaming or heating chambers, for driving machinery, for warming buildings or
conservatories, for steaming clothes or fabrics and for other purposes.
The feed tank I, I, may be in communication with a vessel, or water pipe and be
supplied by gravity, or it may be supplied by a force pump.
The permanent chamber FF when placed within the feed tank is supplied with
water, or any other liquid that may be used (for distilling purposes for instance) by
a tube T leading from the tank 1 thro' the chimney space S. S.
A guard. U. is placed inside the perforations surrounding the bottom of casing. D. D.
for the purpose of helping to direct the current of heat or consumed air up the
chimney space S. S.
Again the valve B may be made to take the form of a piston, and made to give
direct action to a lever for moving machinery.
The feed pipe T may be fitted with a valve to open only inwards.
Again when our device is required in a special and portable form for special objects
we may carry from the apex K fig. IV of the cone A, fig. IV a steam pipe into a closed
cowl, m. fig. IV. or pipe into which the heated steam is delivered, the surface of which
cowl or pipe is thus brought to a high degree of temperature, the closed cowl is
formed with a perforated shed at its periphery and the condensed steam is shed onto
the feed tank which conveniently surrounds the casing; or if a tube is used, a small
pipe performs the same office.
Having now particularly described & ascertained the nature of our invention, and
in what manner the same is to be performed, we declare that what we claim is
I The hollow cone or chamber open at the bottom, in combination with a weighted
valve, for the purpose of causing by steam pressure only a thin film of water, or
liquid, to cover the bottom of the vessel in which the cone or chamber is placed, and
thus to cause the very rapid and economical generation of steam on the continued
application of heat, as substantially set forth.
II The cone or chamber in combination with vessels supplied with air and heat
passages and pipes for the conveyance of steam and introduction of water as
substantially described.
III. The cone or chamber in combination with a cowl, or tube, for distribution of
heat condensation of steam, vapourizing the gases arising from the lamp or other.
heating device, as substantially described.
