Improvements in the Construction of the Joints of Steam Pipes and
Connections of Culinary Utensils and other similar Vessels.
I GEORGE FOWLER of 10 Foster Street, Maidstone, in the County of Kent,
Soldier, 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 relates to the hermetically closing by water of vertical and
angulated ascending and descending joints of low pressure steam pipes and
connections of vessels and utensils in which steam may be used; and at the same
time providing a self acting safety steain valve.
The object of my invention is to construct and arrange that the said joints and
connections be effectually closed when water is placed in them, thus forming &
liquid seal, which prevents the escape of steam at the said joints and connections
of the pipes, vessels and utensils, until a certain pressure is obtained; when the
steam pressure exceeds that required the steam safety valve is established by the
steam pressure forcing the water or other liquids from the said joints and
connections, the pressure within the pipes, vessels and utensils being thus relieved
by allowing the steam to escape; the condensed water within the pipes, connections
or vessels when the pressure is relieved falling back into the joints and connections,
again thus hermetically closing them and in this manner, as aforesaid, establishing
the self acting safety steam valve. The construction and adaption of the said
joints and connections being so arranged that all superfluous water or other liquids,
caused by condensation, collecting in the said joints and connections passes within
the said pipes, vessels and utensils, except when it is preferable to remove the
condensed liquids from the liquid seal, by connecting a pipe (with or without a
stop-cock) with the water and other liquids,-
-see drawing a,-which close the said
joints and connections.
To enable my invention to be understood I will describe how it can be carried
into practice, by reference to the accompanying drawings, in which similar
reference letters indicate similar parts throughout the drawings. The said drawings
to be considered as a part of the Specifications.
Fig. 1. is a vertical section through a steam pipe showing the joint hermetically
closed by liquids, the said liquids being indicated by a,
Fig. 1 shows another way of making and applying my invention to the joints
of steam pipes.
The indent d, seen in Fig. 1 and Fig. 14 is applied to my invention to permit
of the free circulation of the liquids in the said joints and connections.
a, indicates the liquid which herinetically closes the joint or joints and connections,
and enters into the completion and formation of the self acting safety steam valve.
Fig. 2 and Fig. 2 show my invention applied to the inside of cooking utensils
and other similar vessels. Fig. 2 represents another vessel or utensil standing
within the liquid closed connection.
Fig. 2 shows the lid of a utensil in a similar position to the second vessel
seen in Fig. 2.
Fig. 3. is a vertical section, showing the steam outlet pipe from the boiler closed
by a removeable cap c, the said cap being fixed in position, when necessary, by an
attached "T-piece" b, the dotted vertical lines represent a pipe which has been

to the said removeable cap.
The principle and applicability of my invention is suitable for any sized pipe
joint, utensil or vessel, the said pipe joints utensils and vessels being made of tin,
copper, iron, or any other flexible materials.
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 :-
:-
1. The construction and use of steam pipes with joints of the kind hereinbefore
described and as shown in Fig. 1. and Fig. 14 or of any other similar design which
may be effectually closed by a liquid seal.
2. The manufacture and use of utensils and other similar vessels, with connec-
tions of the kind hereinbefore described and seen in Fig. 2 and Fig. 24 or of any
other design which may be closed with a liquid seal.
3. The closing of steam outlet pipes, of low pressure, by the removeable cap c,
and T-piece b, or other similar fastenings, and the securing of steam connected
pipes as herein before described and seen in Fig. 3.
4. The novelties of my invention which I claim are the construction of the
joints of pipes without screws, the said joints having free verticity and like the
connections of the utensils and vessels are hermetically closed by liquids, each joint
or connection being a safety steam valve.
