An Improved Tap or Cock.
I, ALEXANDER JAMES ELI, of the firm of Hughes, Eli, & Hughes, of
76 Chancery Lane, London, W.C. Patent Agent, do hereby declare the nature of
this invention (a communication to me from abroad by Alfred Godwin Chapman,
of Woonoona, in the Colony of New South Wales, Teacher), 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 an improved mode of constructing taps or cocks whereby
they shall be automatically closed when released. This is effected by attaching
a spring one end to the plug and one end to the case so that when the plug is turned
and a fair way opened for the water the plug shall be caused to resume the normal
or closed position by the tension of the spring. The spring may be attached to the
plug either above or below it.
And in order that this my invention may be fully understood and readily carried
into effect I will now proceed to describe same with reference to the accom-
panying drawings, and letters and figures of reference marked thereon, similar letters
referring to like parts throughout the figures.
Figure 1 is a view of a bib cock shewn partly in vertical sectiou, the spring being
placed below the plug.
Figure 2 is an under plan partly in section, the section being taken on the
line 1-2 of Figure 1.
Figure 3 is a plan view of the part that is cut off from Fig. 2.
Figure 4 is a similar.view to that shewn in Figure 1 but with the spring above
the plug.
A, is the body of the cock. B is the plug chamber that is formed with a water
tight recess b, below the plug C. This chamber or recess is for the reception of
a helical spring D, one end of which reposes in the slot d formed in the bottom of
the plug chamber B. The other end of the spring D lies within a corresponding
slot d in the base of the plug C.
The spring D when released from tension will hold the plug C in a position such
that the plug way shall be at right angles to the water way of the body of the
cock and consequently will stop the flow of the fluid. The top of the plug
chamber B is provided with a collar or sleeve E for the purpose of retaining the
plug C within its chamber B. In Figure 1 the way is shewn open and the spring D
in a state of tension; when the plug is released the spring D will immediately turn
round through an angle of 90° and will close the way. Figure 4 is merely a
modification of Figure 1 and shews the spring placed above the plug the spring
chamber being in this case dispensed with.
It is obvious that for large and heavy cocks a spring may be placed both above
and below the plug in which case the construction of the cock would be a modi-
fication of Figures 1 and 4 combined.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination with the plugs of taps and cocks of one or more helical springs,
one end of which spring or springs shall engage with the plug case while the
other end shall engage with the plug as and for the purposes herein set forth.

page_text: 2. The general arrangement, construction, and combination, of parts in my
improved tap or cock as herein specified and as illustrated in the drawings.
