Improvements in and relating to Water-gauges.
I, HEINRICH BLANKE, of 6 and 7, Braustrasse, Leipzig, Plagwitz, Germany,
Manufacturer, 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:-
With the water-gauge shown in the annexed drawing the water or steam, in
case of break of the glass, is intercepted by a sliding stop-valve.
In this drawing, Fig. 1 is a partly vertical section; Fig. 2 a similar section
at right angles of Fig. and Fig. 3 an elevation of the gauge.
This sliding stop-valve indicated by e has an incision by means of which it
moves on the pin e connecting the two crank-disks f¹ and f and said stop-valve
is guided between these latter and the walls g¹, g², g³ of the chamber h. One of
the disks (f) is journaled in the stuffing-box i and the other (f) in the recess k,
and on the part extending through the stuffing-box i the disk' f carries the
handle or operating lever 1.
The lever, operating the said disks and therefore the stop-valve c, being placed
in the vertical position (see Fig. 2) the gauge is ready for use, the stop-valve c
then being placed in a position allowing steam or water, entering through the
passage m the chamber h, by turning around the stop-valve c to reach the glass
through the hole of the removable seat n.
When the glass breaks, the water or steam, coming along the passage m into
the chamber h, applies the movable valve c upon the seat n thereof, thus stopping
the water-gauge automatically, so that neither steam nor water can escape.
The water-gauge may also be stopped, at will, by giving the lever 1, the direction
shown in Fig. 3, in such a way that it is no longer perpendicular, but inclined
backwards and, in this position, presses the valve against the seat n, thus
completely intercepting the passage of water or steam.
To establish the communication between the hole of the seat n, the chamber h,
the passage m and the boiler, the lever is placed in the position indicated by
dotted lines in Fig. 3; by turning the lever 7 to give it this position the stop-
valve c moves towards the upper wall g³ of the chamber h, thus establishing the
communication between the different abovementioned parts. The nut
unscrewed, allows of the cleaning of the seat n and the passage m, the operating
lever being for this purpose placed in the position indicated by dotted lines.

Finally I wish it to be understood that the sliding stop-valve c herein described,
may also be employed as a stopping device in the place of cocks, valves and the
like.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is: .
A water-gauge with a sliding stop-valve having an incision d, by means of
alme moves on a nin e between two crank-disks f¹ and f² and

page_text: is guided between these latter and the walls g¹, g² and g³ of the chamber h for the
purpose of intercepting the water or steam automatically in case of break of the
glass, substantially as described and shown in the annexed drawing.
