PROVISIONAL SPECIFICATION.
Improvements in Cocks and Valves.
I, ALFRED HODGSON SMITH, 92 Carlton Road, Nottingham, Brass Founder, do
hereby declare the nature of this invention to be as follows:-
I construct the seat of the cock or valve with the orifice of the required shape, the
top of the orifice is conical, with the narrowest part of the cone terminating in.an
horizontal seat or flange, the cock or valve plug or stop plato is formed the reverse to
the conical and flanged seat, when a plug is employed it may form the lower end of
the stein or spindle which passes through the gland and stuffing box, but if a stop
plate is employed the lower edge is turned conical to fit the conical part of the seat,
and its underside is either perforated or turned out to receive a portion or portions of
"woodite or other suitable compound, portion of which spreads over the underside
of the horizontal flange of the stop plate, which when screwed down presses onto the
flange of the seat, below the conical part, thus sealing the valve both at the upper
conical, and lower horizontal seats. When a plug is employed it or the barrel is
perforated or slotted, the perforations or slots being filled with "woodite or other
suitable compound. Such arrangements ensures a tighter and more endurable cock
or valve.

SPECIFICATION.
Improvements in Cocks and Valves.
ALFRED HODGSON SMITH, 92 Carlton Road, Nottingham, Brass Founder, 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:-
Figure 1 shows a sectional side view of an improved single stop cock or valve.
Figure 2 shows a side view of an improved check cock or valve, and
Figure 3 a sectional side view of an improved stop cock or valve with an additional
bottom stop valve.
I construct the seat A of each cock or valve see Figure 1 with the top of the orifice
turned conical, the narrowest part of the cone terminating in an horizontal seat or
flange B, the plug or stop plate is formed the reverse to the conical and flanged seat,
when a plug is employed it may form the lower end of the stem or spindle C which
passes through the gland and stuffing box.
But if a stop plate is employed the lower edge D is turned conical to fit the conical
part of the seat, and its underside is turned out as shown by the dotted lines to receive
a portion of woodite E which when screwed down presses onto the flange B of
the seat, thereby sealing the cock or valve both at the upper conical, and lower
horizontal seats.
In my improved check cock or valve, shown at Figure 21 form the seat conical
with an horizontal flange as above described and employ a stop plate D with a spindle
above and a plug below, the underside of the plate being turned out to receive
woodite E, which seals the seat to form a non-return cock or valve when the pressure
of steam, air, gas, or liquid is taken off from the bottom side.

page_text: In the cock or valve shown at Figure 3 the top of the seat is conical and flanged to
receive a stop plate D and woodite E as before described, the underside of the seat
also being turned conical and flanged to receive a bottom stop plate D' provided with
woodite which when screwed into the position shown forms a stop cock or valve,
when the upper stop plate has to be removed for repairs or other causes. Or the
lower stop plate may be employed to regulate the quantity of steam, air, gas or liquid
to be passed through the cock as required, or to prevent leakage through the cap D³.
The lower stop plate is carried by a screw threaded rod D² held by a screw threaded
cap D³.
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
The employment of woodite with upper and lower plugs or stop plates in cocks or
valves substantially as described and illustrated in the Drawings annexed.
