PROVISIONAL SPECIFICATION.
Improvements in Taps for Beer, Spirits, and other Liquids.
JOHN WILLIAM ROGERS of 16 Carter Street Walworth in the County of
Surrey, Turner, and JAMIES RETTIE of 1 Westmoreland Road Walworth in the
County of Surrey Engineer do hereby declare the nature of this invention to be as
follows:-
According to our invention we form a tap in the ordinary manner with the
exception that on a convenient part of the cylinder we form a projection the object
of which is hereinafter explained. We now form a cap having an internal annular
groove of such form and dimensions as may be required to take a spiral spring of
sufficient strength to actuate the plug of the tap in the process of shutting off. At
one point of the groove we place a stop against which one end of the spring always
rests the spring following round in the groove until the other end abuts on the
other side of the aforesaid stop. Now by means of a slot in the cap and a slight
compression of the spring the cap can be placed on the cylinder in such manner
that the projection on the cylinder and the stop in the groove come close together-
the two ends of the spring keeping them in that position when the tap is shut. In
the top of the cap we make a hole in order to allow the plug of tap to pass through
when placing it in its position. The plug we form with a collar which-when the
plug is home in its position-bears upon the cap and is fastened thereto by means
of screws or other suitable method. Now when the tap is turned on the spring is
compressed or if a pull spring extended-for we use either-and when let go the
spring rebounds and throws the plug back to its cut-off position thus preventing
any waste from imperfect closing as in the case of ordinary taps.

COMPLETE SPECIFICATION.
Improvements in Taps for Beer, Spirits, and other Liquids.
JOHN WILLIAM ROGERS of 16, Carter Street, Walworth, Surrey, Turner,
JAMES RETTIE of 1 Westmorland Road, Walworth, Surrey, Engineer, 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 consists of a plug cock or tap the plug of which is kept in position
by a spring placed in the head so that it is impossible for it to be left open the
accompanying drawings fully explain the method of working (A) is the body of
the cock or tap (B) is the plug (C) is a collar fastened to body (A) and having a
small projecting piece (G) (D) is a cap fixed to spindle (B) with another projecting
piece (F) covering the whole top of the cock or tap and resting on the collar (G)
containing a spiral spring (E) fitted inside a V shaped groove cut in the body of
the cap it will be seen by reference to plan No. 1 that on turning the spindle (B)
the spring (E) is compressed but on the spindle being released the spring forces the
plug back to its original position.
Plan No. shows an arrangement of two springs to allow the plug (B) to be.
turned either to the right or left.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. A plug cock or tap controlled by a spring or springs substantially as described
in the Specification.
2. The manner of fixing the spring or springs to control the plug substantially as
described in the Specification and drawings.
