Improvements in Water Gauges and Gauge Cocks.
We, THEODOR CHRISTIAN ERICH ROSE Manufacturer of Wilhelminenstrasse No. 18
Altona and CARL HERMANN STAMER, Machine Engineer of Eimsbüttelerstrasse
No. 52, Hamburg, both in the Empire of Germany, 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 water gauges and gauge cocks and has for its purpose to
provide suitable closing devices for both and efficient contrivances for causing, in
water gauges, the steam to be instantaneously and automatically shut off when the
glass bursts and allowing the closing of the valve to be with facility obviated on the
blowing through of the steam.
Referring to the accompanying drawing;
Fig. 1 illustrates a water gauge with the improvement applied thereto, the lower
delivery cock being, for clearness's sake, represented as turned for 90 degrees.
Fig. 2. is a top view.
Fig. 3. a horizontal section, and
Fig. 4. a vertical section along line xy Fig. 2, of the upper part, and
Fig. 5. a vertical section of the lower part of the improved water gauge.
The upper part A consists of a casing G having attached to its rear side the
muffle K and to its front, opposite to the latter, the cleaning aperture, which is closed
by means of the screw O.
The valve spindle S, adjustable by means of a screw thread in the nut m and
tightened outwardly through the stuffing box p, is so provided as to traverse the
cleaning device at an angle of 30 degrees. The internal extremity of the spindle S
carries by aid of a pivot the plug T of soft copper, the sharp-edged face of which
establishes a tight closing in the conic bore a of the passage to the steam generator.
Said copper plug tapers towards its free extremity in order to allow its tight fit in the
conic bore to be re-established when. necessary by renewing its sharp circular edge.
Sideways of the muffle K is provided the tube muffle R, and in front of the latter the
valve chamber V communicating through an aperture D with the casing G and
through the passage C with the tube muffle, thereby allowing the steam to flow
through the upper part A of the water gauge in the direction indicated by
arrows.
The valve chamber is provided, between the aperture D and passage C with a
diaphragm s having a conic bore tightly closed by means of the sharp-edged copper
plug which is guided in the closing screw P and adapted to be taken out therewith
for cleaning or other purposes.
When the glass bursts, the steam rushing through the casing G causes the valve to
be instantaneously closed, while, in order to obviate the closing of the valve when the
steam blows through, the screw spindle 9, provided in the upper side of the valve
chamber, is slightly turned, thereby arresting the copper plug t.
The automatic closing of the lower part B of the water gauge, which part, from G
to K, is of the same construction with the analogous portion of the upper part A-
except that the chamber G is in direct communication with the respective tube muffle,
the portion 9 P being omitted-is effected by means of the copper plug t¹ which is
guided either in the bow of a closing screw, as the plug in the upper part A, or in
the casing of the delivery valve E. The tight closing of the latter is likewise
ensured by means of a copper plug provided on the valve spindle and extending into
a conic bore.
t
The method described, of ensuring a tight closing of the valves is applicable in a
like manner to gauge cocks.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what
we claim is :
1) In water gauges, the combination, with a tube muffle R, of a vertical valve
chamber V, passage C, muffle K, aperture D, diaphragm s with conic aperture,
copper plug t and screw spindle g, substantially as and for the purpose set forth.
2) In water gauges, the combination with the device referred to in claim 1, of the
lower part B of the apparatus, substantially as set forth.
3) The application, for closing water gauges and gauge cocks, of a tapering plug
of soft copper provided on the valve spindle, in combination with a conic bore,
substantially as and for the purpose set forth.
Dated this 22nd day of June 1889.
