A Fullway Valve or Stop Cock.
I, JOHN BOWDEN, of 24, Arnott Street, Hulme, Manchester, in the County of
Lancashire, Brassfinisher, do hereby declare the nature of this invention to be
as follows:-
My invention relates to what are known as fullway valves or stopcocks.
In constructing a valve or stopcock of the type mentioned it would contain
the following parts (see diagram).
A. Is the spindle for raising or lowering the dise (D).
B. The body of valve or stopcock.
D. The valve disc attached to spindle by means of screwthread, which may be
cither square or V thread.
C. The convex part of valve disc.
F. The face of the disc which is turned true and ground smooth.
G. The seating on the body of valve or cock which is turned true.
S. Taper grooved slides fixed on either side of valve body clear of the steam way.
The disc (D) is dropped into the body of valve or cock between the two taper
grooved slides, the face (F) of the disc, and the seating (G) on the body of valve
will become perfectly paralell thus when pressure is applied by means of
spindle (A) it will force the faces firmly together making the valve perfectly
steam or water tight.

JOHN BOWDEN, 24, Arnott Street, Hulme, Manchester, in the County of Lanca-
cashire, Brassfinisher, 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:--
My invention consists of improvements in or relating to fullway valves or stop
cocks.
For purposes of illustration I will now refer to the annexed drawings, in which
Figure 1, is a vertical section of a valve or stop cock constructed according
to my invention.
Figure 2, sectional elevation of groove or guide piece.

page_text: Figure 3, rear view of same.
Figure 4, front elevation of plug or stopper.
Figure 5, plan view of valve at or about -y in Figure 1.
A is the spindle which is provided with a screw thread, this screw thread
passing through a nut N which is movably carried upon the plug or stopper I'
in any convenient manner, being prevented from rotating by means of a pro-
jection engaging in corresponding groove in the body of the valve. The slide or
guide piece is so shaped as to be placed in the body of the valve and when the
inclined surface 1) upon the plug or stopper F comes into contact with the inclined
surface of the guide piece S the surface of the plug or stopper which closes the
aperture is brought into close contact with the seating, so closing the valve and
preventing the passage of the fluid or other substance from same. The seat-
ings G of the body B of the valve are turned so as to form a close fitting surface
between themselves and the bottom of the guide piece S. It will be seen that if
required the sliding piece S may be reversed in position, that is to say, the surface
for closing the seating upon the plug or stopper F may be caused to engage upon
either one or other of the outlet seatings as required, thus reducing the wear and
prolonging the working life of the tap.
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:-
1. In fullway valves or stop cocks; the combined construction and arrange-
ment of the various parts substantially as described and illustrated herein and
for the purpose set forth.
2. In fullway valves or stop cocks: a movable slide or guide piece adapted to
cause a plug or stopper carried upon a screw spindle to close an inlet or outlet
seating, said plug or stopper being operated by the screw spindle through the medium
of a nut carrying the plug or stopper and adapted to allow a certain amount of
movement or play of the plug or stopper in order to ensure a tight joint between
the surface of the plug or stopper and the seating or outlet aperture which it is to
close, all in combination and substantially as described and illustrated herein and
for the purpose set forth.
