Improvements in Bib Cooks.
JOHN DAVEY Queen Street Hitchin Herts Engineer. I do hereby declare the
nature of this invention to be as follows :-
This invention is intended to prevent cocks from bursting by frost, the valve
shutting all water out of the body of the cock, the body of the cock is made straight,
the valve seating being in the hexagonal part of same, the spindle that carries the
valve has two collars or pistons on it, which act as a guide and also prevent the
valve being taken out unless the screw in drawings is first removed, the spindle is
actuated by a screw cap which revolves on same.
In the accompanying drawings Fig. 1 is a horizontal section, A is the body of
cock, B. valve seating C. leather or other washer on valve, D. spindle that carries
the valve E. E. collars or pistons on spindle F. screw cap for opening and closing
valve, G. screw to prevent the removal of spindle and valve from the body of
cock.

JOHN DAVEY Engineer Queen Street Hitchin Herts 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 is intended to prevent cocks from bursting by frost the valve
shutting all water out of the body of the cock. The body of the cock is made
straight the valve seating being in the hexagonal part of same.
The spindle that carries the valve has two collars or pistons on it which act as
guides and also prevent the valve being taken out unless the screw shewn in
drawing is first removed. The spindle is actuated by a screw cap which revolves
on same.
In the accompanying drawing Fig. 1 is a horizontal section. A is the body of
cock; A'A' is the hexagonal part referred to above; B valve seating; C leather
or other washer on valve; D spindle that carries the valve; EE collars or pistons
on spindle; F screw cap for opening and closing valve; G screw to prevent the
removal of spindle and valve from the body of cock.
In the accompanying drawings in which I have represented as examples my
invention carried into practice in two different ways
Fig. 1 is a horizontal section of the cock,
Fig. 2 is the other form of the cock.
Like letters indicate like parts throughout the drawings.
Referring to Fig. 1A is the body of the cock; A A¹ is the hexagonal part;
B valve seating; C leather or other washer; D spindle that carries the valve
around which is an annular space to intercept any water passing the piston;
EE collars or pistons on spindle; F screw cap for opening or closing valve;

page_text: G screw to prevent the removal of spindle and valve from the body of cock;
H an auxiliary nozzle to convey any water that may pass the piston into the main
nozzle.
In the cock represented in Fig. 2 A is the body of cock; A' A¹ is the hexagonal
part B valve seating; C and C¹ leather washer on loose valve or jumper;
D spindle that carries the valve around which is an annular space to intercept any
water passing the piston; E collar or piston; F screw on spindle for opening and
shutting valve; G screw to prevent the removal of spindle and valve from the
hody of cock; H auxiliary nozzle to convey any water that may pass the piston
into the main nozzle.
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. The combination with a straight bodied cock of a valve spindle with one or
niore pistons on the same with an annular space or chamber in the same as shewn
at D in drawings to receive the water that may pass the piston and convey the
same into the auxiliary nozzle H.
2. The combination with a straight bodied cock of a spindle which screws into
the body of cock Fig. 2 and having one or more pistons on the same to form an
annular space or chamber at D to receive the water that may pass the piston and
convey it into the auxiliary nozzle H.
