Improvements in Water Gauges for Steam and other Bollers.
I, ALEXANDER WILLIAM TICKLE Manufacturer's Agent of 6 Fenchurch
Buildings in the City of London do hereby declare the nature of this invention
to be as follows (as attached hereto) :-
My invention relates to water or fluid gauges wherein it is desirable to secure
unobstructed access from the lower extremity of the vertical branch of the lower
half of a water gauge in line with and parallel to the glass tube, that is to say :—
from the position which has heretofore generally been used for the attachment of
the discharge cock.
It is desirable that all the internal passages of the gauge, including that by
which the water and steam passes to the discharge cock should be easily accessible
to a rod passed through the clearing hole in the usual way, thereby rendering the
removal of incrustation or sediment perfectly easy..
It is also desirable that this should be accomplished without having to remove
the automatic check valve or other fitting inserted, from its position.
For these purposes I find it necessary to make two passages in the bottom of the
casting of the lower half of the water gauge instead of one as heretofore used,
and I hereby set out how and in what manner my said invention is to be accom-
plished that is to say :-
I construct the lower half of the gauge with a passage to the discharge cock,
the point of outlet of the said passage being at or about right angles to the barrel
of the main stop cock fitted to the body of the lower half of a water gauge, which
stop cock is about midway between the point of attachment to the boiler and the
face of the water gauge, being used to shut off the main or horizontal passage of
the gauge. The point of junction of the said passage to the discharge cock with
the main or horizontal fluid passage is upon the inner wall of the chamber or
recess formed by the junction of the vertical branch which supports the glass
tube, with the horizontal or main branch which is attached to the boiler or
container. Therefore if a line were drawn through the centre of the passage
to the discharge cock and another line through the centre of the main or hori-
zontal fluid passage, their point of meeting would form the apex of a triangle.
It follows that a clear and unobstructed passage is secured from, and in line
with, the glass tube, to the lower extremity of the vertical rectangular branch
of the bottom half of the water gauge. A passage can be formed through the
lower extremity of the said branch in line with and parallel to the glass tube.
This passage can be stopped by a screw nut similar to that upon the upper
half of the water gauge through which the glass tube is inserted, or it can be
used for the insertion and attachment of an automatic check valve and its support
similar in character to that described in the Specification of Patent of John
Marshall number 511 of 1867, or any other fitting that can be usefully or con-
veniently attached in line with the glass tube.
It will thus be seen that my invention consists in forming the passage to the
discharge cock so that it can be cleared from the usual clearing hole at the same
time as the main horizontal fluid passage, without removing the automatic check
valve, or other fitting that may be inserted, from its position. Also that the
outlet of the passage to the discharge cock is separate and distinct from the outlet
of the passage in line with the glass tube the latter being situated at that point
heretofore generally adopted for the attachment of the discharge cock, that is to
say, in line with the glass tube,

page_text: It is obvious that modifications of my invention can be effected in many ways
without departing from the nature of my said invention, that is to say :-
By forming the passage to the discharge cock, so as to meet the main or hori-
zontal fluid passage at a point between the main stop cock and the point of attach-
ment of the lower half of the water gauge to the boiler.
By leading off the passage to the discharge cock by a pipe or extension of the
casting in any direction.
Or by inserting a bibnosed or other discharge cock at that point to which the
clearing screw is usually attached to the lower half of a gauge.
In such cases however the passage to the discharge cock could not be cleared
from the clearing hole, as in the arrangement I have hereinbefore described.

COMPLETE SPECIFICATION.
Improvements in Water Gauges for Steam and other Boilers.
I ALEXANDER WILLIAM TICKLE of 6 Fenchurch Buildings in the City of
London, Manufacturers Agent 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:-—
My invention relates to water or fluid gauges wherein it is desirable to secure
unobstructed access from the lower extremity of the vertical branch of the lower
half of a watergauge in line with and parallel to the glass tube, that is to say :-
from the position which has hitherto generally been used for the attachment of the
discharge cock.
It is desirable that all the internal passages of the gauge, including that by
which the water and steam pass to the discharge cock should be easily accessible
to a rod passed through the clearing hole in the usual way, thereby rendering the
removal of incrustation or sediment perfectly easy.
It is also desirable that this should be accomplished without having to remove
the automatic check valve, or other fitting inserted, from its position.
For these purposes I find it necessary to make two passages in the bottom of the
casting of the lower half of the gauge, instead of one as heretofore used, and I
hereby set out how and in what manner my said invention is to be accomplished;
that is to say :-
I construct the lower half of the gauge with a passage to the discharge cock, (a),
the point of outlet of the said passage being at or about right angles to the barrel
of the main stop cock (b) fitted to the body of the lower half of a watergauge,
which stop cock is about midway between the point of attachment to the boiler,
and the face of the watergauge, being used to shut off the main or horizontal fluid
passage of the gauge. The point of junction of the said passage to the discharge
cock with the main or horizontal fluid passage is at a point about the centre of the
chamber or recess formed by the junction of the vertical branch which supports
the glass tube with the horizontal or main branch which is attached to the boiler
or container; therefore, if a line were drawn through the centre of the passage
to the discharge cock, and another line through the centre of the main or horizontal
fluid passage, their point of meeting would form the apex of a triangle (d). It
follows that a clear and unobstructed passage is secured from and in line with the
glass tube to the lower extremity of the vertical rectangular branch of the bottom
half of the watergauge. A passage (e) can be formed through the lower extremity
of the said vertical branch in line with and parallel to the glass tube. This
passage can be stopped by a screw nut similar to that upon the upper half of the
watergauge stopping the passage through which the glass tube is inserted, or it
can be used for the insertion and attachment of an automatic check valve and its
support, similar in character to that described in the Specification of Patent of

page_text: John Marshall, No. 511 of 1867, or any other fitting that can be usefully or
conveniently attached, in line with the glass tube.
In the accompanying drawings :-
:-
Figure 1 is a side elevation, partly in section.
Figure 2 is a front view of the same in section.
It will thus be seen that my invention consists in forming the passage to the
discharge cock so that it can be cleared from the usual clearing hole at the same
time as the main horizontal fluid passage is cleared, without removing the auto-
matic check valve or other fitting that may be inserted from its position. Also
that the outlet of the passage to the discharge cock is separate and distinct from
the outlet of the passage in line with the glass tube, the latter being situated at
that point heretofore generally adopted for the attachment of the discharge cock,
that is to say, in line with the glass tube.
It is obvious that modifications of my invention can be effected in many ways
without departing from the nature of my said invention, that is to say; By
forming the passage to the discharge cock so as to meet the main or horizontal
fluid passage at a point between the main stop cock and the point of attachment
of the lower half of a watergauge to the boiler. By leading off the passage to
the discharge cock by a pipe or extension of the casting in any direction; or by
inserting a bib-nosed or other discharge cock at that point to which the clearing
screw is usually attached to the lower half of a gauge. In such cases however,
the passage to the discharge cock could not be cleared from the clearing hole as
in the arrangement I have hereinbefore described.
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. In the lower half of a watergauge the construction of the passage to the
discharge cock substantially as and for the purposes described.
2. In the lower half of a watergauge the construction of a separate and distinct
passage through the bottom of the casting in line with and parallel to the glass
tube, to be used for the insertion of an automatic check valve or other fitting, or
to be stopped by a screw nut, substantially as described.
3. The improved arrangement and apparatus hereinbefore described, substan-
tially as set out, and illustrated by the accompanying drawings.
Dated this 17th day of August 1891.
