Improvements in Water Gauges for Steam Bollers and the like.
I, FREDERICK HENRY HAUSMAn, of 22 Vesey Street, New York, in the City,
County and State of New York, United States of America, Gentleman, do hereby
declare the nature of this invention to be as follows
The object of my invention is to simplify the construction of water gauges
thereby lessening the cost of production, and at the same time greatly facilitating
the mode of operation.
With this object in view I will proceed to describe my invention in detail.
In my invention I employ an inner and outer gauge glass, the outer one for the
purpose of protecting the inner glass from atmospheric action and accidental
breakage, and I employ a simplified means for adjusting these glasses as follows:-
The inner glass is provided at both its ends with rubber gaskets of a novel shape.
A seating plate is provided at the lower end of the gauge, and is screwed into or
otherwise secured to an ordinary angle valve controlling the flow of water from
the boiler to the gauge. Said seating plate is provided with annular grooves for
receiving the lower ends of the said glasses.
The form of the gasket which I employ is of a double U shape in cross section.
With the aid of this gasket a perfectly steam tight joint is effected between the
lower end of the glass and the seating plate. A nick or recess is cut in the groove
against the edges of which nick the gasket will press when in position, thereby adding
to the security of the joint.
I provide an improved means of connecting the gauge glass with the valve, of the
following construction :-
For the aforesaid purpose I employ what I please to term a steam pin, which is
screwed into an ordinary angle valve. This pin has a lower extension which is
provided on its surface with a male thread, by means of which it is screwed into a
collar. Said collar is provided at its lower end with a groove adapted to receive
the upper end of the inner gauge glass with the gasket whereby the said glass is
held rigidly in an upright position. The said gasket prevents any leakage around
the steam pin aforesaid. A loose collar is placed over the collar upon which it is
free to rise and fall. This loose collar is intended for the purpose of holding the
outer protecting glass in a vertical position, and it is adapted to be lifted either by
the first mentioned collar or independently of said collar.
When it is desired to remove both the inner and outer gauge glasses, the hand
wheel is revolved to the right, whereby the collar and loose collar will be caused to
travel upwards together, releasing the hold of said collars from the glasses, when
said glasses can be readily removed and new ones inserted. The ordinary gauge
protecting rods are employed in this my invention to prevent the glasses from being
accidentally struck.
For the purpose of better indicating the amount of water contained in the
boiler and gauge 1 employ a float. This float is composed of cork or other suitable
buoyant material, having a wire or narrow strip of non-corrosive or rust proof
metal passed through it, the ends of said wire being somewhat spread apart for the
purpose of preventing the said wire from working out of the cork, and at the same
time forming a support for preventing the float from entirely closing the opening
or passage during the operation of blowing off the sediment, etc.

page_text: In the case of cork being used for the float I prefer to coat it with asbestos or
other heat proof paint.

Improvements in Water Gauges for Steam Boilers and the like.
I, FREDERICK HENRY HAUSMAN, of 22 Vesey Street, New York, in the
County and State of New York, United States of America, Gentleman, 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 for steam boilers, and its objects are to
simplify the construction of water gauges, and to add to their safety, lessening the
cost of production and at the same time greatly facilitating the mode of operation.
With these objects in view, I will proceed to describe my invention in detail,
reference being had to the accompanying drawings in which like letters of reference
indicate corresponding parts in all figures alike.
Figure 1 is a side elevation of the gauge with the outer gauge glass partly in
section.
Fig. 2 is a central vertical section of the same.
Fig. 3 is a plan view of the improved rubber gasket employed with the gauge.
Fig. 4 is a transverse section of the same, taken on line 1-1 of Fig. 3.
Fig. 5 shows the end of valve with a pin across its opening to prevent the ball
valve from rolling into the boiler.
Fig. 6 is a side elevation of the inner gauge glass, with the gaskets in position.
Fig. 7 is a transverse sectional view. of a modified form of gasket.
With this gauge I employ both outer and inner gauge glasses; the outer one for
the purpose of protecting the inner glass from atmospheric changes and accidental
breakage.
A represents the inner glass, and B the outer protecting glass. The inner glass
is provided at both ends with rubber gaskets of a novel shape. A seating plate or
metal head C is provided at the lower end of the gauge, and is screwed into an
ordinary angle valve C, which valve controls the flow of water from the boiler to
the gauge. Said seating plate C is provided with circular grooves bc on its upper
surface for receiving the lower ends of the glasses A and B.
The form of the gasket which I employ, as shown, is double U-shape in cross
⚫ section. With the aid of this gasket an absolutely steam tight joint is effected
between the lower end of the glass tube A, and the seating plate C. A nick.or
recess c¹ is cut in the groove b, against the edges of which nick the gasket will press
when in position, thereby adding to the security of the joint.
To connect the gauge with the upper or steam valve I employ what I term a
steam pin D which is hollow to permit the passage of steam, and is screwed at .it>
upper end into an ordinary angle valve D. The lower end of the pin D is als
provided on its exterior surface with a male thread, by means of which it is
screwed into a collar E Said collar E is provided at its lower end with a
groove d adapted to receive the upper end of the inner gauge glass A with gasket a,
whereby the said glass is held rigidly in an upright position. The said gasket
prevents any leakage between the collar E and inner gauge glass A. A loose
collar Fs placed over the collar E. upon which it is free to rise and fall. This
loose collar F is intended for the purpose of holding the outer protecting glass B
in a vertical position, and to that end is provided with a groove e¹ to receive the
upper end of said outer glass. Said collar Fis adapted to be lifted.either by
the collar E, or independently of said collar.
When it is desired to remove both

page_text: the inner and outer gauge glasses, the hand wheel E' of said collar E is revolved
to the left, whereby the collar E and loose collar F will be caused to travel
upwards together, releasing the hold of said collars.from the glasses, when said
glasses can be readily removed, and new ones inserted. For convenience in handling,
a lock nut e is screwed on the steam pin D, after the collar E, and a suitable
packing is inserted between said lock nut and collar to effect a tight joint, and
prevent any steam from escaping between the threads of the steam pin and collar.
Screw threads are also provided on the outer surface of the lock nut e, and corre-
sponding threads are also cut for their engagement in the hand wheel E', of the
collar E, and a rim g¹ of hard rubber is fitted around said hand wheel for convenience
in handling. A slight turn will release said lock nut, when it will travel upwards
with the wheel E¹ upon the steam pin D.
The gauge is also provided with an automatic cut-off of the following
construction :-
Both upper and lower valves have an auxiliary chamber H containing a ball.
valve (preferably of type metal). Said auxiliary chamber has a recessed valve
seat I adapted to be closed by the ball in the event of the inner gauge glass
becoming accidentally broken. In such event of said inner glass breaking, the
increased rush of steam and water will drive the ball into its seat, thereby effecting
an automatic cut-off, until the pressure is released by the ordinary closing of the
valve proper. The open end of the auxiliary chamber H where communication is
made with a boiler is provided with a pin f¹ placed transversely across said opening
for the purpose of preventing the ball valve from rolling out of said chamber into
the boiler.
The steam valve stem G is provided with a projecting pin g which is adapted to.
enter the opening connecting the valve chamber proper with the auxiliary
chamber, and push the ball valve i from its seat I back into the auxiliary chamber.
This pin also serves to clear the said passage h from any sediment which might.
collect at this point.
A pet cock of ordinary construction is screwed into the lower valve of the gauge-
for the purpose of blowing off sediment, etc., from the glass.
In Fig. 7 will be seen a modified form of gasket which I may employ, said gasket
being of a similar construction to that represented in Figs. 3 and 4, but having an
additional groove or recess h³ around the other groove, said groove h¹ being intended
as a seat for the outer glass B.
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. An improved water gauge comprising an inner and an outer gauge glass, a.
seating plate having grooves and a gasket to receive the lower ends of said glasses,
said grooves having each a nick or recess, into which the gasket will become
embedded, substantially as and for the purposes set forth.
2. An improved water gauge, comprising an inner and an outer gauge glass, the
valves of said gauge having an auxiliary chamber, said chamber having a recessed
valve seat to receive a ball valve, and a check across the opening of said auxiliary
chamber to prevent the ball valve from rolling out of said chamber, substantially as
shown and described.
3. An improved water gauge, comprising an inner and an outer gauge glase, a.
steam pin screwed into the upper valve of said gauge, a collar supporting said steam
pin a loose collar over and around said first named collar, and adapted to be moved
vertically to secure and release the outer gauge glass, and a lock nut to secure said
first named collar upon the inner gauge glass substantially as and for the purposes
shown and described.
4. The improved gasket for water gauges, substantially as shown and described
herein.

page_text: 15. The improvements in water gauges, substantially as and for the purposes
hereinbefore described set forth and illustrated in the annexed drawings.
