IMPROVEMENTS IN TAPS OR COCKS
Year: 1884

page_text: I FREDERICK BARTON HILL, of 30 Fleet Lane, in the City of London, Clerk do
hereby, declare the nature of the said invention for "IMPROVEMENTS IN TAPS OR
COCKS" to be as follows:-
My invention relates to improvements in taps or cocks having rotating plugs and
the invention consists in providing the plugs of such taps or cocks with a spiral or
other suitable spring whereby in the event of the tap or cock being left open or
turned on from accident or from any other cause it will be automatically turned
off and thus avoid the waste of spirits or other liquid which would otherwise
occur.
A suitable method of carrying out my invention is as follows I form the plug
of the tap with a groove in its circumference in which. groove I place the said
spring which may be a spiral spring one end of which is suitably attached to the
plug of the tap or cock the other end of the same being attached to the shell
thereof.
By this construction when it is required to draw the liquid from the tap or cock
the plug is turned by means of its handle in the ordinary way but must be held in
the open position until the required amount of liquid has been drawn off when the
handle being released the plug of the tap or cock will by means of its spring be
automatically turned into position to close or turn off the tap or cock.
My improvements can be easily applied to existing taps or cocks.

page_text: I FREDERICK BARTON HILL of 30 Fleet Lane, London Clerk do hereby declare
the nature of the said invention for "IMPROVEMENTS IN TAPS OR COCKS" 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 improvements in taps or cocks having rotating or
turnable plugs and the invention consists in providing the plugs of such taps or
cocks with a spiral or other suitable spring whereby in the event of the tap
or cock being left open or turned-on, from accident or from any other cause, it will
be automatically turned off and thus avoid the waste of spirits or other liquid
which would otherwise occur.
A suitable method of carrying out my invention is as follows:- I form the plug
of the tap with a groove in its circumference in which groove I place the said
spring which may be a spiral spring one end of which is suitably attached to the
plug of the tap or cock the other end of the same being attached to the shell or
body thereof. A stop projection on the plug and stops on the body, or vice versa,
are, provided in substantially the ordinary manner for the open and closed
positions of the tap.
By this construction when it is required to draw the liquid from the tap or
cock the plug is turned by means of its handle, in the ordinary way, but must be
held in the open position until the required amount of liquid has been drawn off,
when the handle being released the plug of the tap or cock will by means of its
spring be automatically turned into position to close or turn off the tap or cock.
My improvements can be easily applied to existing taps or cocks.
In the drawings Fig 1 is a side view partly in section, of a tap fitted according
to my invention showing the plug in closed position.
Fig 2 is a side view showing tap in open position.
A, is the plug, B, the body of tap, C, is the spring attached at a, to the
plug A, and at b, to the body B. d, is a stop projection on 'the plug A, and e, e¹,
are stops on the body B, for open and closed positions. The spring C, may lie in
a groove formed in and around the plug, or as shown in the drawings, the groove
may be dispensed with and the spring be laid around the plug. D, is a cap which
is screwed at D', to the body B, and is of such configuration as to accomodate the
internal arrangement of the spring and to present a finished exterior. It will be
clearly understood that the spring is in its normal position when the tap is closed
and that the spring is put in tension whilst the tap is held open.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
"
In a tap or cock with rotating or turnable plug the spring C, acting for the
purpose of automatically closing the tap or cock as herein set forth.
