JAMES SAMUEL KINGSTON Plumber No. 1 Douro Villas Snakes Lane Woodford
Essex 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 invention consists of a cone shaped Boiler having inner and outer walls
separated by a spiral plate forming a spiral flue, above the line of the fire box
portion of boiler the box of the boiler terminating below the ash pit.
An entrance through Boiler from fire box or furnace to spiral plate forming spiral
flue through which the smoke and hot gasses pass, also a central fuel feed pipe or
magazine connected or cast in boiler at a point near its apex, and terminating over
the fire also a header pipe or elbow flanged and bolted on same also a flanged
socket to receive return water, also a collar cast, riveted, or bolted, on to the
outside of casing or covering of spiral flue for the purpose of attatching smoke pipe.
The outer wall of, boiler above the line of fire box is in the form of doors, which are
preferably cast iron and are used for the purpose of cleaning the flue. The frame
for carrying this outer wall or flue cleaning doors is secured at the apex and is also
bolted on to a flange secured to boiler above the fire box. Fig. 1. is a front view
of Boiler which can be made of cast, riveted, or welded Iron, or steel or copper,.
having outer walls Q, Q, which on the left side is shown broke away for the purpose
of showing the spiral flue (or part of it). The water wall of boiler is also shown in
this view by A. at that point where outer wall is broken away.
The fire box portion of Boiler is denoted by Y. which with the rest of the boiler
is preferably cylindrical, and has feed or inspection door de noted by L. shaker door

page_text: or cover denoted by N. also ash pit doors denoted by M. the openings covered by
these doors all pass through the water spase of boiler and enter fuel chamber or
fire box. The outer casing or wall of boiler is denoted by QQ the bolts for securing
same to flange of Boiler by R the outlet on the top of Boiler can be in the form of
a header with a number of outlets from it or it can be in the form of a tee piece,
elbow, or socket, threaded or otherwise, flanged and bolted to the top of boiler and
is denoted by P. the bolts for securing same is denoted by T. the cover or door for
the fuel feed pipe or magazine is denoted by V. Fig. 2. is a sectional view of
Fig. 1. denoted by A. The fuel pipe or magazine is denoted by G. the cover or
door to same by V. the fire box is denoted by B. the flue from same passing through
water spase to spiral flue is denoted by D. the grate is round and revolves on a
pin or pivot cast on it and is denoted by H. the Bridge iron or bearer for
supporting grate is denoted by I. resting on lugs or brackets J. J. cast or bolted to
the sides of fire box B. E. E. E. E. E. E. E. denotes the spiral plate dividing the
inner and outer walls of Boilers to form a spiral flue whereby the products of
combustion will traverse spirally around the water spase of Boiler. The water
spase is denoted by W. W. W. W. W. and as the Boiler diminishes in diameter
according to distance from the fire the hot gasses at the apex have less water to
heat. Said spiral plate or flue starts at the opening of flue D and terminates at
the smoke collar denoted by F. a check damper is denoted by Z, and is intended
for use to check the fire or to close during the process of cleaning the flues. The
fire box B is surrounded by water at its sides also under the ash pit with the
exception of spaces taken by the smoke flues feed and ash pit doors. The inner
shell of boiler is supported under ash pit by brases or legs denoted by O. O. cast,
riveted or bolted thereto. The opening for the return water is denoted by S. and
can be in the form of a socket or elbow, flanged or screwed; the feed or inspection
door is denoted by L. a shaker or lever is denoted by K. and is used as a means of
revolving or rocking the grate to free itself of ashes, the door or cover of the
opening through which the shaker or lever passes into pocket in grate is denoted
by N. The outer casing of Boiler on which are hinged doors for the purpose of cleaning
the flue is denoted by Q. Q. Secured under the flange at the apex of Boiler and
bolted on flange at the top of fire box by bolts R, R. The header or outlet pipe
ie denoted by P. and can be in the form of a tee with one or more outlets from same
as denoted by U, U, U, U, U or if prefered can be an elbow or a socket, flanged,
screwed or otherwise. The same is secured to boiler by bolts denoted by T. Mud
ports or openings for the purpose of cleaning incrustation out of Boiler are shown
on Fig. 2 by the figures 9. 9. 9. 9. 9.
Having now particularly described and ascertained the nature of my said
invention what I claim is
1. A cone shaped boiler having a spiral plato forming a spiral flue around that
part of boiler which is above the line of fire box and terminating at its apex and
protected by an outside casing in which are a number of doors for the purpose of
giving free access for thoroughly cleaning the flue.
2. A cone shaped boiler made of any suitable metal, with the water circulating
around the fire box and under the ash pit, thereby making the boiler safe as regards
setting fire to a floor or walls and at the same time uterlising waste heat from the
grate.
3. A cone shaped boiler as described with the flue on the outside, making it a
quick heating boiler, for heating Greenhouses, Public, or Private Buildings by hot
water as its shape causes no resistance to free circulation. The formation of eddies
or counter currents are avoided.
4. The outer casing being in the form of doors, allows the thorough cleaning of
the flue.
5. A cone shaped boiler which by attaching ordinary guages and safety valve can
be used as a steam boiler for high or low pressure maintaining a water line.

page_text: 6. A cone shaped boiler as described with a space between the water wall and
the external air filled with hot gasses or the products of combustion thereby
preventing loss of heat to the water through radiation to the external atmosphere.
7. A cone shaped boiler having a fuel feed pipe or magazine riveted, bolted
welded or cast in or near its apex, and terminating over the fire box or furnace, to
be larger in diameter the further it extends down for the purpose of preventing the
fuel from budging substantially as described.
