We, JOHN HENRY GALLOWAY and JAMES WILLIAM GALLOWAY of 100 Bark
Street, Bolton in the County of Lancaster, Engineers and Brassfounders, do hereby
declare the nature of our said invention to be as follows:-
Our invention relates to improvements in steam traps which are used to effect the
discharge of condensation water from steam pipes and other apparatus in which steam
is used, and has for its object that of preventing the ball float collapsing through
external pressure, or bursting through the expansion of air_contained therein, which
are the chief causes of so many failures in steam traps. To overcome these defects
we mount the ball float on a hollow arm or spindle attached in any convenient manner
to the valve spindle; the latter extending through a stuffing box to the outside of the
cistern containing the same. The outer end of the valve spindle is provided with a
passage communicating with the hollow arm or spindle carrying the ball float to
admit atmospheric air into the float and protect it from the results or defects before
mentioned.

page_text: Improvements in Steam Traps.
Wo, JOHN HENRY GALLOWAY and JAMES WILLIAM GALLOWAY of 100 Bark
Street, Bolton in the County of Lancaster, Engineers and Brassfounders, do hereby
declare the nature of our said invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
Our invention relates to improvements in steam traps which are used to effect the
discharge of condensation water from steam pipes and other apparatus in which steam
is used, and has for its object that of preventing the ball float collapsing through
external pressure, or bursting through the expansion of air contained therein, which
are the chief causes of so many failures in steam traps. Fig. 1 is a sectional elevation
of a steam trap constructed on our improved principle-Fig. 2 is a plan of same with
cover removed-Fig. 3 is an end view of Fig. 1, and Fig. 4 is an enlarged part
sectional plan through line A. B. in Fig. 1.
C is the cistern of the steam trap; D the cover; E the valve; F the valve seat,
and G the ball float. The ball float G is attached to the hollow arm or spindle H
which passes through the eye of the valve spindle I. The hollow arm or spindle H is
attached to the T piece J provided with the hollow tubes K which extend through
the stuffing boxes L to the outside of the cistern C and are open to the atmosphere,
by which atmospheric air is admitted into the ball float G, which also allows the heated
air to escape, thus preventing it from collapsing through external pressure, or bursting
through the expansion of air contained therein, which overcomes the principal defects
and removes the chief cause of so many failures in steam traps. The condensation
water from steam pipes and other apparatus is admitted to the cistern C by the inlet
pipe M and emitted by the pipe N when the valve E is raised by the action of the ball
float G and hollow arm or spindle H. The cistern (can be cleansed of dirt and other
deposits by removing the cover O, which is secured by the crossbar P and screw R.
Having now particularly described and ascertained the nature of our said Invention
and in what manner the same is to be performed we declare that what we claim is
1. Admitting atmospheric air into the ball float to prevent it collapsing through
external pressure or bursting through the expansion of air contained therein, sub-
stantially as and for the purposes herein set forth.
2. In combination with a steam trap the use of the hollow arm or spindle H and its
attachments constructed to admit atmospheric air into the ball float, substantially as
and for the purposes herein set forth and as shown on the drawings.
