I, SAMUEL HALL, of Hollins Mount, Unsworth, near Bury, in the County of
Lancaster, Millwright, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in kitchen boilers and has for its object
to provide means which will effectually prevent the explosion of kitchen boilers and
which are not liable to get out of order.
To this end my improved kitchen boiler consists of a cistern having a lid bolted
thereto and a valve operated by the rise and fall of the water in the boiler or
cistern. The seat of the said valve is arranged in the said lid and the valve body
connected with a spindle carrying near its end a float guided vertically in a socket
on the bottom of the boiler or cistern and in a bridge secured to the inner side of
the lid, the stem of the valve being guided in the valve seat. By preference
I employ a mushroom type of valve. The said float is supported by the water
in the boiler or cistern and when the water is admitted into the latter, it raises
the float and closes the aforesaid valve whilst when the water has fallen to a level
at which explosions may occur the valve opens and permits the excess of pressure
to escape at once.

Improvements in Kitchen Boilers.
I, SAMUEL HALL, of Hollins Mount, Unsworth, near Bury, in the County of
Lancaster, Millwright, 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 improvements in kitchen boilers and has for its object
to provide means which will effectually prevent the explosion of kitchen boilers
and which are not liable to get out of order.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 being a vertical section and Fig. 2 an end view of my improved kitchen
boiler.
In carrying out the invention and referring to the figures generally my improved
kitchen boiler consists of a cistern a having a lid 6 bolted thereto and a valve c
The seat'd of
operated by the rise and fall of the water in the boiler or cistern a.
the valve I preferably arrange in the lid b and the valve c connected with a
spindle d carrying near its lower end a float e guided vertically in a socket fon the
bottom of the boiler or. cistern a and in a bridge g secured to the inner side of

page_text: the lid b, the stem of the valve being guided in the valve seat c!, the said bridge
in some instances may however be dispensed with.
By preference I employ a mushroom type of valve, as shown in the drawing.
The float e is supported by the water in the boiler or cistern a, the cold water
being admitted into the latter near its bottom by means of the pipe i and the hot
water leaving the boiler or cistern through the pipe k arranged near the top.
The float e causes the valve to remain closed until such time when the water has
fallen to near a level at which explosions may occur when the said float drops and
opens the valve, thus permitting the excess of pressure to escape at once through
the valve seating c¹.
In order to protect the valve c from injury I may employ a cover / over the
top of the boiler or cistern and a pipe m communicating with the space between
the same through which when the valve opens the steam may escape.
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-
"In kitchen boilers."
1st. The general construction and combination of parts constituting my
improvements operating substantially as and for the purpose specified.
2nd. A kitchen boiler having a float e vertically guided and adapted to control
the action of a valve c having its seat c¹ in or on the lid b, which float keeps the
said valve closed whilst sufficient water is in the boiler and opens the same when
nearly empty, all substantially as set forth.
Dated this 13th day of February 1896.
