Improvements in Stop Cocks and Taps.
I WILLIAM BARBER PRESS of 5 Lansdowne Villas High Road Leytonstone in
the County of Essex Mechanic do hereby declare the nature of this invention to be
as follows:-
This my invention relates to stop cocks and taps for water and other liquids, and
is a modification of the screw down taps and cocks now in use and consists first in
the formation of the tap body which I will hereafter explain secondly in the method
of fixing the screw top to the body, thirdly in the system of valving and packing
and fourthly in making the screw piston & cross handle in one.
I now proceed to describe my invention.
I cast the body of the tap or stop cock with a raised seating the centre of which
is the inlet. Around that seating is a channel or groove commencing the outlet (the
inlet and outlet ends can be of any desired length or shape) the top of the said
channel or groove is a broad flange on the edge of which I cut an external screw.
A dome shaped cap with an equal flange having internal thread and bored to fit
screw piston covers the groove which is kept from revolving by a key piece passing
through a slot cut in the edge of the body screw flange. A nut preferably with
six or more sides passes over the dome cap and screws on the body thus keeping the
two flanges firmly together. The screw and handle are in one. A plain fitting is
above the screwed portion grooved for the reception of packing. At the bottom of
the screw is a neck and ball end. The jumper is inade with a slotted top that
passes over the ball and prevents the screw working out. Now the method of
valving and packing is as under, a disc of leather or prepared rubber the full size
of the dome cap fange is put on the jumper screw, on that also is put a leather pad
the two firmly secured by an under screw nut. The handle screw screwing into
the dome cap is packed in the groove provided which packing passing up and
down the tube neck of the dome cap keeps the handle steady. The slot of the
jumper is then placed over the ball of the screw. The top complete is then put on
the body with the fixed key in the slot provided, the disc of leather or rubber being
between the flange of the body and the Hange of the dome cap is kept firm by the
nut as before explained.

I WILLIAM BARBER PRESS of 5 Lansdowne Villas High Road Leytonstone in
the County of Essex Mechanic 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 my invention relates to improvements in stop cocks and taps for water and
other liquids the object of the invention being to provide a tap that will shut off

page_text: with greater certainty with less strain on the screw than is required for the screw
down taps now in use and give a stendier flow of water. And that my invention
may be better understood l'annex a sectional elevation of that portion of my tap
wherein my improvements appear.
I now proceed to descrilie iny invention referance being had to the accompanying
drawing and to the figure and letters of reference marked thereon.
Fig. 1 is a sectional view of the working portion of my bib tap or stop cock.
A is the body cast in brass or other metal with prominent raised seating 0.
Around that seating is the channel or grooved coinmenceing the outlet .J. I is the
inlet. The top of the body A is a broad flange the edge of which is screwed
preferably left handedly.
is the cover of the body A having a flange of the same diameter the said cover
being screwed to fit the pressure screw D and fortneil with a socket to receive the
packed plain fitting.
D is the screw piston having a plain fitting above the screwed portion and
grooved for the reception of packing. At the bottom of the screw is n neck and
ball end.
C is the clamping nut with six or more sides and screwed to fit the body.A.
E is the jumper made with a slotted top that passes over the, ball of the screw
piston D with a level surface of greater diameter than the seating 'O and screwed at
the bottom to fit nut H.
F'is a leather or prepared rubber disc.
G the seating pad.
The dise and pad Gare placed on the screw of the jumper E and held firm by
the nut H the outer edge of disc F being clamped between the flanges of A and B
by the nut C thus confining the water when the tap is open to the inlet and outlet
chambers of body A.
Kis the packing in groove provided on piston D that works with the screw in
socket of cover B keeping the crutch handle stendy.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what
claim is
First. In taps and stop cocks the body so formed as to leave a prominent raised
seating and water chaunel around.
Secondly. The method adopted and explained of securing the cover B to the
body A by the nut C.
Thirdly. The packing being fixed to the screw piston D and worked with
the screw in a socket provided in the cover all substantially-ns hereinbefore set
forth, and
Fourthly, claim the general combination of parts shewn and described.
Dated this 22nd day of March 1895.
