COMPLETE SPECIFICATION.
Improvements in Water Gauges.
I, HENRY K. GILBERT, of Lockport, in the County of Niagara 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 certain new and useful improvements in water
gauges, and it pertains more particularly to means for preventing wearing or
cutting away of the sight tube at the steam end. It is a well known fact that
the sight tubes of water gauges will wear or become cut away at the end where
the steam acts thereon. It is true that gaskets have been applied at this point,
but heretofore they have failed to effectually serve the purpose for which they
were intended, and notwithstanding their presence the glass has worn
away.
I provide a gasket which protects the glass from its upper end to a point
below the nut which serves as a connection between the glass and the con-
nection with the gauge cock; and the flange of the said gasket receives the end
of such connection to form a tight packing at this point. I provide further a
gasket which rests upon the end of the sight glass and in some instances has a
thinner portion extending down within the sight glass, and upon this gasket is
supported a small tube which extends within the sight glass, being held out of
contact therewith, and serving to protect the glass from wear upon the inner
surface. It will thus be seen that I thoroughly and effectually protect the glass
at all points where it is liable to be worn or cut away and thus the life of the
glass is materially lengthened.
Other objects and advantages of the invention will hereinafter appear and the
novel features thereof will be specifically defined by the appended claims.
The invention is clearly illustrated in the accompanying drawings, which,
with the letters of reference marked thereon, form a part of this specification, and
in which
Fig. 1 is a vertical section through a portion of a sight glass of a water gauge,
showing the application of my invention.
Fig. 2 is a perspective view of the upper portion of the sight glass with my
improvements in position.
Fig. 3 is a perspective view of my improved gasket removed.
Like letters of reference indicate like parts throughout the several views.
Referring now to the details of the drawings by letter, A designates a portion
of a sight glass of a water gauge of known construction, except as hereinafter
specified with relation to the manner of protecting the upper end thereof.
B is my improved gasket. It comprises a flange portion, a, from opposite sides
of which extend the thinner portions b, which are designed to embrace and
closely hug the glass as seen in Figs. 1 and 2, so as to be frictionally held thereon.
The under edge of this flange portion is rounded or beveled as seen at c, to

page_text: the sight tube and extending within the said tube out of contact therewith, sub-
stantially as and for the purpose specified.
5. As an improved article of manufacture for use in connection with water
gauges, a rubber gasket having a flange with thinner portions extending from
opposite sides thereof, substantially as and for the purpose specified.
