PROVISIONAL SPECIFICATION.
Improvements in connection with High Pressure Kitchen Boilers.
I JOHN PATON of 29 Newry Street Holyhead, County of Anglesey, Engineer
do hereby declare the nature of this invention to be as follows:-
The object of this invention is to prevent the numerous kitchen boiler explosions
caused by severe frost; I accomplish this object by means of a device for forcing
hot water directly from the circulating cylinder up into the bath room or any of
the upper rooms of a house and in order to show in what manner the same is to be
performed I refer to the accompanying drawing in which let h, represent the boiler,
c, the circulating cylinder, b, a common ball valve cistern, p, a pipe open to the air
above the roof of the house, and v, a double acting valve having the lower face of
leather and the spindle loaded with the heavy weight W, to prevent leaking, also
let m, represent à cord and n, a pipe led into the bath room: Then by inspection
it may be seen that the ball valve cistern will be fed from the water service
pipe w, that it will communicate freely with the circulating cylinder and both will
be open to the atmosphere, consequently the water will always be about the same
height in both of them; Also it may be seen that by pulling on the cord the
weight W, will be lifted clear of the valve spindle when the high pressure service
water will instantly raise the valve closing the communication between the ball
valve cistern and the circulating cylinder and opening for itself a direct passage
into the bottom of the circulating cylinder. Theu because it has sufficient pressure
and because it is a bad conductor of heat it will force hot water up into the bath
room; Also, it may be seen that by letting go the cord the weight will force the
valve into its normal position when communication between the ball valve cistern
and the circulating cylinder will be restored consequently the flow of hot water
will instantly stop and that in the pipes will immediately fall down into the cistern ;
The pipes being thus always free from standing water will not be liable to be
injured by frost.

Improvements in connection with High Pressure Kitchen Boilers.
1 JOHN PATON of 29 Newry Street Holyhead County of Anglesey Engineer
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 :-
It is said that the hot water cistern and the pipes in connection with high
pressure kitchen boilers require to be thoroughly protected from frost, that to do
this adds so much to the cost of installation that the work is seldom well done and
in consequence a number of boilers explode and numerous pipes burst during every
hard winter.
The object of the applicant is to show the Board of Trade and the general
public that the serious losses above referred to may be wholly avoided by using

page_text: the novel, absolutely safe and comparatively inexpensive arrangement herein
described and shown in the accompanying drawing in which let A, represent the
water service pipe; E, a common ball valve cistern (the overflow is not shown)
F, the circulating cylinder; H, the boiler; I, a pipe open to the air above the
roof of the house, and K, a double acting valve loaded by the weight L, to a
pressure considerably greater than that of the service water. Also let M, represent
a flexible wire cord and N, a pipe led into the bath room.
Then by inspection it may be seen (1) that the ball valve cistern will be fed by
the water service pipe, that it will communicate freely with the circulating cylinder
and that both will be open to the atmosphere, therefore, the water will always
stand in both about the height indicated by the dotted line (2) that the load may
be raised clear of the valve spindle by the lever T, in the bath room when the high
pressure service water will instantly raise the valve closing the communication
between the ball valve cistern and the circulating cylinder and opening for itself a
direct passage into the bottom of the latter. Then because it has sufficient
pressure
and because it is a bad conductor of heat it will force hot water up into
the bath room (3) that the load may again be lowered on to the valve forcing it
into its normal position, restoring communication between the ball valve cistern
and circulating cylinder, stopping the flow of hot water and allowing that in the
pipes to fall down into the circulating cylinder while an equal quantity of cold
water will escape by the ball valve cistern (4) that the pipes above the dotted
line will never contain stagnant water therefore cannot become blocked with ice,
that the pipes below the dotted line will be thawed by heat from the circulating
cylinder should they from disuse become frozen.
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
The device for raising hot water from the lower to the upper rooms of
buildings substantially the same as herein described and shown in the drawing.
Dated this 7th day of July 1896.
JOHN PATON.
