IMPROVEMENTS IN WATER-GUAGES FOR, STEAM BOILERS
Year: 1884

page_text: I FERDINAND BOSSHARDT of the firm of Bosshardt & Grant, Mechanical and
Consulting Engineers and Patent Solicitors of 24 & 32 Bulls Head Exchange
Chambers Market Place Manchester in the County of Lancaster, do hereby declare
the nature of my invention for "IMPROVEMENTS IN WATER-GUAGES FOR, STEAM
BOILERS" communicated to me from abroad by Antoine Guyot of Montreuil sous
Bois in the Republic of France to be as follows:-
The invention consists in combining a safety valve of a certain construction
with the water-guage of a steam boiler and has for its object to reduce the cost of
such appliance and increase its reliability. To this end I form a bracket of suitable
material being at one end or near to it provided with a ball valve.
The latter may be formed separately and screwed to the bracket or form a part
thereof near to a flange formed on the bracket for the purpose of securing the same
to the boiler by means of bolts.
The opposite end of the said bracket forms a beud and is connected to the glass
of the water-guage at its extremity by means of a union.
The said bend is also provided with two plugs which can be readily removed for
the purpose of cleaning the passage formed in the said bracket from the safety
valve to the said bend and passage from the bend to the glass or water guage.
Between the flange and the said bend a tap is arranged which serves to shut off
the water in case of accidents, such as the glass breaking, or when cleaning the
glass.
:
The safety valve may be applied to and in combination with the water-guages
already existing on boiler by simply securing the flange of the bracket forming the
safety valve to the boiler by means of two screws and connecting the bend to the
glass on water-guage by means of a union.

COMPLETE SPECIFICATION.
I FERDINAND BOSSHARDT of the firm of Bosshardt & Grant, Mechanical
& Consulting Engineers & Patent Solicitors of 24 & 32 Bulls Head Exchange
Chambers Market place Manchester in the County of Lancaster, do hereby declare
the nature of my invention for "IMPROVEMENTS IN WATER-GAUGES FOR STEAM
BOILERS," which has been communicated to me from abroad by Antoine Guyot of
Montreuil-sous-Bois in the Republic of France, and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:
The invention consists in combining a safety valve of a certain construction
with the water gauge of a steam boiler and has for its object to reduce the cost of
such appliance and increase its reliability.
And in order that my invention may be better understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference corre-
sponding letters indicating like parts in the various figures.
Fig 1 on the annexed drawing represents a longitudinal section of a safety valvo
constructed in accordance with my invention. Figs 2 and 3 are also longitudinal
sections showing modifications thereof.
In carrying out my invention, see Fig 1, I form a bracket a of suitable material
being at one end or near to it provided with a ball or valve A.
The valve seating may be formed in the bracket, a see Fig 2, or in a separate
piece B¹ see Fig 1, and which is screwed to the end near the flange of the
bracket a. This flange is provided with holes and serves for securing the safety
valve to the boiler.
The opposite end of the said bracket forms a bend and is connected to the glass
of the water gauge D, at its extremity by means of a union E.
The said bend is also provided with two plugs F and G which can be readily
removed for the purpose of cleaning the passage formed in the said bracket from
the safety valve to the said bend, and from the bend to the glass or water-gauge D.
Between the flange and the said bend a tap C is arranged which serves to shut off
the water in case of accidents such as the glass breaking or when cleaning the
glass.
The safety valve may be applied to and used in combination with the water
gauges already existing on boilers by simply securing the flange of the bracket
forming the safety valve to the boiler by means of two screws and connecting the
bend to the glass on water-gauge by means of a union E..
The ball valve may be arranged in the bracket a either between the tap C and
the boiler or between the tap C and the glass D as shown in Fig 3.
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-
The combination of a safety-valve with a water gauge applied to a steam boiler
and the various modifications thereof substantially as described and illustrated.in
the annexed drawings."
