PROVISIONAL SPECIFICATION.
Improvements in Hot Water Boilers for Domestic Purposes.
I, HENRY LEGGOTT, of Market Street, Bradford, in the County of "York,
Ironmonger, do-hereby declare the nature of this invention to be as follows:-
This invention relates to certain improvements in the form of hot water boilers in
combination with Marsh's "Improved Furnace".and for which Letters Patent were
granted No. 16409-1888 whereby greater efficiency in heating with the least
expenditure of fuel is effected and consists of an inverted cone shaped boiler with
the base of the cone parallel to the hot plate of the fixture.
The current of heat is arranged to pass against one side of the cone then under
the apex and up the other side when the hot water boiler damper is drawn, but if
this damper is closed the heat impinges upon the fireside of the cone and passes
away over the base of the cone between the boiler and the hot plate, thus imparting
heat to the hot plate and the boiler to a limited extent when the hot water boiler
damper is shut.
By this arrangement a good supply of hot water is constantly provided for
ordinary purposes with the least expenditure of fuel and when an extraordinary
supply is required, the hot water boiler damper is withdrawn thus allowing the
current of heat to pass over a great superficial area of the surface of the hot water
boiler.

COMPLETE SPECIFICATION.
Improvements in Hot Water Boilers for Domestic Purposes.
I, HENRY LEGGOTT, of Market Street, Bradford, in the County of York,
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 :-
This invention relates to certain improvements in the form of hot water boilers in
combination with Marsh's "Improved Furnace" having fixed or moveable louvre
bars, and for which Letters Patent were granted No. 16409 of 1888 whereby
greater efficiency in heating with the least expenditure of fuel is effected than
hitherto, and consists of an inverted cone shaped boiler with the base of the cone
parallel to the hot plate of the fixture.
In order that my invention may be fully understood I will describe the same by
making reference to the accompanying sheet of drawings in which
Fig. 1. represents a sectional elevation through line a. b. of Marsh's improved
fire range, shewing my improved boiler in position, and
Fig. 2. is a plan of same with hot plate removed.
The boiler is indicated by the letter A. and is a cone shaped boiler fixed in an
inverted position with the base parallel to the hot plate B. of the fixture.
When the boiler damper C. is shut as shewn by Fig. 1. the flame passes into the
hot air chamber D. and impinges against the side A¹ of boiler A. and passes
away through flue E. in the direction of arrows to oven F. F. on the right and left
respectively according to the adjustment of the oven dampers, thus imparting heat
to the hot plate B. and to a sufficient area of the boiler A. for the supply of hot.
water for ordinary purposes.

page_text: "
The boiler A. may be " sett a little lower than the hot plate B. forming an
opening for the flame to pass over the base of the cone: either arrangement will
accomplish my object, but by preference I fix the boiler as illustrated by Fig. 1.
When an extraordinary supply of hot water is required, the hot water damper C.
is withdrawn, the flame impinges to a certain extent against the side A' of the
boiler A. under the apex and against the side A³ thus passing over a greater
superficial area of the surface of the boiler than above described.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
The combination of a cone shaped boiler with a range having fixed or moveable
louvre bars, substantially in the manner herein shewn and described.
