Improvements relating to Stop Cocks or Valves for Water Service
Pipes and for like purposes.
I, EDMUND DAVIES, of Summerville, Meole-Brace, near Shrewsbury, in the
County of Salop, Shoeing Smith, do hereby declare the nature of this invention
to be as follows:
This invention consists of improvements relating to stop cocks or valves for
water service pipes and for like purposes, my object being to construct a simple
and effective cock or valve, and to so arrange the same as to permit of the auto-
matic draining of the pipes on the outlet side when the cock is closed.
In the construction of a stop cock in accordance with my invention for use with
house water service pipes, form the metallic body or valve chamber with inlet
and outlet apertures and also with a drainage outlet at the lower part of the chamber.
The stop cock is connected with the supply pipe preferably on the exterior of the
house or building, being arranged in a small sump or pit at a level which is
lower than any part of the service pipe within the building, such sump or pit being
in a position convenient of access for operation and for inspection of the cock.
The valve proper is preferably of the piston type and is connected with a screwed
operating stem which projects through a stuffing box and gland, its outer ex-
tremity being suitably formed for engagement by an operating key or spanner.
The valve seat is formed immediately below the inlet aperture, but above the
outlet aperture, and the valve is closed by drawing it tightly against the under-
side of the seat. When the valve is thus closed the water in the whole range of
the service pipes will flow out through the drainage aperture herein befora
described.
The stop cock is opened by screwing down, the valve until it is pressed on to a
seating around the drainage aperture. The water will then flow through the
valve body to the house service pipes but will be prevented from escaping through
the drainage outlet.
With my improved stop cock or valve the water service pipes throughout a
house or building can be readily and conveniently emptied of their water in the
time of frost, or when any repairs of such pipes or their fittings are required.

Improvements relating to Stop Cocks or Valves for Water Service
Pipes and for like purposes.
I, EDMUND DAVIES, of Summerville, Meole-Brace, near Shrewsbury, in the
County of Salop, Shoeing Smith, do hereby declare the nature of this invention

page_text: 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 improvements relating to stop cocks or valves for
water service pipes and for like purposes, my object being to construct a simple
and effective cock or valve, and to so arrange the same as to permit of the auto-
matic draining of the pipes on the outlet side when the cock is closed.
The accompanying illustration to be hereinafter referred to is a sectional eleva-
tion of a stop cock constructed in accordance with my invention.
In the construction of a stop cock in accordance with my invention for use with
house water service pipes I form the metallic body or valve chamber with inlet
and outlet apertures as A and B respectively and also with a drainage outlet C
at the lower part of the chamber. The stop cock is connected with the supply
pipe preferably on the exterior of the house or building, being arranged in a
small sump or pit at a level which is lower than any part of the service pipe within
the building, such sump or pit being in a position convenient of access for opera-
tion and for inspection of the cock. The valve proper as D has a pair of
leather or other faces as d and and connected with a screwed operating
stem E which projects through a stuffing box and gland as illustrated, its outer
extremity being suitably formed for engagement by an operating key or spanner.
The seat for the face d of the valve is formed between the inlet and outlet
apertures as shown and the valve is closed against the incoming water by drawing
it tightly against the underside of the seat, the illustration shows the valve in such
closed position. When the valve is thus closed against the incoming water the
face d will be away from its seating on the hollow screw plug F fitting in the
drainage outlet C, and thus the water in the whole range of the service pipes will
flow out through the drainage aperture as shown by the full line arrows. The
dotted line arrows represent the direction of the incoming water when the valve
face dis closed on to its seating and the face d opened or screwed away from
its seating.
The stop cock is opened by screwing down the valve until it is pressed on to the
seating around the drainage aperture. The water will then flow through the
valve body to the house service pipes but will be prevented from escaping through
the drainage outlet.
With my improved stop cock or valve the water service pipes throughout a
house or building can be readily and conveniently emptied of their water in the
time of frost, or when any repairs of such pipes or their fittings are required.
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. The construction and arrangement of a stop cock or valve for effecting the
automatic draining of water service or similar pipes when the cock or valve is
closed substantially as described.
2. An improved cock or valve for water service pipes and for like purposes
substantially as described and as illustrated.
