PROVISIONAL SPECIFICATION.
Improvements in Safety Attachments for Steam Gauges.
I, CHARLES ELY STARR, a citizen of the United States and a resident of 34 East
7th Street, in the City of Portland, County of Multnomah and State of Oregon,
United States of America, Marine Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to water and steam gauges; and the object thereof is to
provide means for instantly closing the communication with the boiler if the steam
gauge or pipe connected therewith should be, broken or bursted; and with this
and other objects in view, the invention consists in the construction, combination
and arrangement, of parts hereinafter described.
The invention is fully disclosed in the following specification:
In the practice of my invention, I provide a tubular plug, which is provided 'at
one end with a screw-thread by which it is connected with the boiler or a pipe which
communicates therewith, and the tubular plug, is provided with an enlarged
chamber, at the opposite end of which is formed an extension, and said chamber
is provided at its upper side with a tubular extension, with which is connected a
glass pipe, which constitutes the gauge or which connects with the gauge, which
may be of any desired form or construction.
Formed in the tubular plug is a valve seat and placed in said tubular plug is
a metal ball valve, the valve seat is conical in form the apex thereof being in the
direction of the central enlarged chamber, and passing through the extension is a
screw-threaded rod or shaft, which is adapted at its inner end to serve as a valve
as shown, and which is also provided with a reduced extension which passes through
the port or opening by means of which the central bore of the tubular plug,
communicates with the chamber.
The rod or shaft is provided with a cap having a screw-threaded flange or rim,
by which it is connected with the extension, and within said cap is placed a packing
ring of suitable material and mounted on the glass tube is a cap provided with
an annular flange or rim by which it is connected with the extension; and the
bottom of the chamber or the casing thereof is provided with an exhaust pipe,
which is provided with a valve and passed transversely through the tubular plug
between the valve seat and in the end thereof, is a pin or bolt which is designed to
prevent the valve, from rolling into the boiler or from being lost or mis-placed.
The operation will be readily understood from the foregoing description.
The tubular plug is connected with the boiler, in the usual manner and the rod or
shaft is withdrawn, so that the extension thereof will not pass through the valve
seat and if in the operation of the device, the tube or the gauge should be broken the
valve will at once be forced upon the valve seat, by the escaping water or steam and
water, and the passage through the said tubular plug and the said chamber will thus
be entirely cut off and the danger of scalding or otherwise injuring the engineer or
other attendant will be obviated.
It will be understood that this is only to provide means for instantly closing the
passage or cutting off the flow of steam, and the port or passage through the valve
seat, may be permanently closed by means of the rod or shaft, which may be screwed
into the casing or chamber so as to close said port or opening in which operation the
valve will be forced from its seat

page_text: When the necessary repairs are made the rod is drawn outwardly so as to admit of
"blowing off" or cleaning out the central chamber after which the rod or shaft is
further withdrawn so as to permit the free operation of the valve, when necessary;
and it will be understood that in "blowing off" the escape is opened.
This device is simple in construction and operation and is well adapted to
accomplish the result for which it is intended, and it is evident that changes in the
form, construction and arrangement of the various parts thereof, may be made
without departing from the spirit of my invention or sacrificing its advantages..

COMPLETE SPECIFICATION.
Improvements in Safety Attachments for Steam Gauges.
I, CHARLES ELY STARR, a citizen of the United States, residing at 34 East
7th Street, City of Portland, County of Multnomah, State of Oregon, United States of
America, Inventor, do hereby declare the nature of this invention, and in what
manner the saine is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention relates to water and steam gauges and the object thereof is to
provide means for instantly closing the communication with the boiler if the steam
gauge or pipe connected therewith should be broken or bursted; and with this and
other objects in view, the invention consists in the construction, combination and
arrangement of parts hereinafter described and claimed.
The invention is fully disclosed in the following specification, of which the
accompanying drawing forms a part, said drawing heing a central, vertical longitudinal
section of the device which constitutes my improvement.
In the practice of my invention, I provide a tubular plug A, which is provided at
one end with a screw thread a, by which it is connected with the boiler or a pipe
which communicates therewith; and the tubular plug A is provided with an enlarged
chamber a at the opposite end of which is formed an extension a³ and said chamber
is provided at its upper side with a tubular extension a with which is connected a
glass pipe C, which constitutes the gauge or which connects with the gauge which may
be of any desired form or construction.
Formed in the tubular plug. A is a valve seat B, and placed in said tubular
plug is a metal ball valve D.
The valve seat B is conical in form, the apex thereof being in the direction of
the central enlarged chamber a2 and passing through the extension a³, is a screw
threaded rod or shaft G, which is adapted at its inner end to serve as a valve as
shown at g, and which is also provided with a reduced extension g' which passes
through the port or opening by means of which the central bore of the tubular
plug A, communicates with the chamber a².
The rod or shaft G is provided with a cap H, having a screw threaded flange
or rim h, by which it is connected with the extension a² and, within said cap is
placed a packing ring of suitable material and mounted on the glass tube C, is
a cap K, provided with an annular flange or rim k, by which it is connected with
the extension at and the bottom of the chamber a2, or the casing thereof is provided
with an exhaust pipe L which is provided with a valve M, and passed transversely
through the tubular plug A, between the valve seat D, and in the end thereof is a
pin or bolt O which is designed to prevent the valve D, from rolling into the boiler
or from being lost or mis-placed.

page_text: The operation will be readily understood from the foregoing description, when
taken in connection with the accompanying drawing, and the following statement.
thereof.
The tubular plug A, is connected with the boiler in the usual manner and the
rod or shaft O, is withdrawn so that the extension g' thereof will not pass through
the valve seat and if in the operation of the device the tube C, or the gauge should:
be broken, the valve D will at once be forced upon the valve seat. B, by the escaping
water or steam and water, and the passage through said tubular plug and the said
chamber a², will thus be entirely cut off and the danger of scalding or otherwise.
injuring the engineer or other attendant will be obviated.
It will be understood that this is only to provide means for instantly closing
the passage or cutting off the flow of steam, and the port or passage through the
valve seat B, may be permanently closed by means of the red or shaft G, which
may be screwed into the casing or chamber a² so as to close said port or opening
in which operation the valve D, will be forced from its seat.
When the necessary repairs are made the rod G is drawn out so as to admit of
blowing off or cleaning out the central chamber a² after which the rod or shaft G is
further withdrawn so as to permit of the free operation of the valve D, when necessary ;.
and it will be understood that in "blowing off" the escape pipe L is opened.
This device is simple in construction and operation and is well adapted to accomplish
the result for which it is intended, and it is evident that changes in the form,.
construction and arrangement of the various parts thereof, may be made without
departing from the spirit of my invention or sacrificing its advantages.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. The combination with a water or steam gauge, of a tubular plug by which it
may be connected with the boiler said plug being provided with an enlargement or a
chamber with which the gauge communicates and with a valve seat through which
is formed a port or opening which opens into said chamber, and a ball valve
mounted therein, and adapted to be forced upon said seat by the escaping steam or
water when the gauge or pipe by which it is connected with the tubular plug is
broken, substantially as shown and described.
2. The combination with a tubular plug, for connecting a water or steam gauge.
with a boiler, said plug being provided with an enlarged chamber with which the
gauge is connected, and with a valve seat through which a port or opening is
formed, of a ball valve mounted therein and adapted to be forced upon said valve
seat and a shaft or rod passing through said chamber, the inner end of which is
adapted to serve as a valve to close said port or opening, and provided also with a
reduced extension which is adapted to pass through said port or opening, substantially
as shown and described.
3. The combination with a tubular plug, for connecting a water or steam gauge
with a boiler, said plug being provided with an enlarged chamber with which the
gauge is connected, and with a valve seat through which a port or opening is.
formed, of a ball valve mounted therein, and adapted to be placed upon said
valve seat and a shaft or rod passing through said chamber, the inner end of which
is adapted to serve as a valve to close said port or opening, and provided also with a
reduced extension which is adapted to pass through said port or opening, said
rod or shaft being screw threaded and said chamber or the casing thereof, being.
