PROVEMENTS IN COCKS OR VALVES AND APPARATUS FOR DRAWING OFF REGULATED
QUANTITIES OF LIQUID."
This Invention has for its object improvements in cocks or valves and apparatus
for drawing off regulated quantities of liquid.
The shell or body of the cock or valve is formed with a transverse passage
through it, in which passage there is a partition or diaphragm with a seating for a
valve closing a water way through it. The inlet for the supply is immediately
beneath the partition or diaphragm, and the outlet is immediately above it. So far
the arrangement is similar to that described in my Provisional Specification, No.
5276, in the year 1878.
I now form a cylindrical chamber over the partition or diaphragm; it is closed
by a cover at the top having on it a stuffing box, through which the stem of the
valve passes. The valve stem has a cupped leather fixed upon it fitting the cylin-
drical chamber. These parts together with a coiled spring surrounding the stem are
inserted from the top into the chamber when the cover is removed, and the valve is
then fixed on to the lower end of the valve stem from the under side.
The spring
becomes compressed between the partition or diaphragm and a collar upon the valve
stem, and it tends to hold the valve to its seat.
When the valve has been inserted the transverse passage is closed at its lower
end by inserting a screw plug, and at its upper end by screwing on the cover
already mentioned. In this case there is a small perforation for allowing the
escape of air from the part of the cylindrical chamber over the cup leather, and the
size of this aperture can be adjusted by means of a screw with a coned end.
To draw water the valve is pressed down by a lever so as to remove the valve
from its scat; at the same time the cupped leather is moved down within the
cylindrical chamber, the air beneath it passing freely to the upper side. The cup
rn...

page_text: leather however prevents the air returning, so that the valve cannot close until the
air has escaped by the regulated aperture provided for the purpose. In order that
the lever by means of which the valve is opened may not be held or fixed down
after it has done its work of opening the valve I have devised the following arrange-
ment: I connect with the handle by a joint a pawl or hook, which when the
handle is moved to open the valve engages with the outer end of the lever, which
is weighted, and it lifts it until from the movement of the lever around its centre it
escapes from the pawl or hook; the weighted end of the lever then falls, leaving
the valve free to close.. As the handle goes back, the pawl or hook yields by
turning about the pin which connects it with the handle, and so passes the end of
the lever.
Where it is desired to open and close valve cocks by means of a lover or handle
making a partial rotation, I fix to the stem of the valve a cap ovehanging and sur-
rounding the stuffing box, through which the valve stem passes. I form an inclined
slot in the side of the cap, and fix in the part of the body or shell of the cock con-
taining the stuffing box a pin projecting through the slot. The lever or handle is
applied to the valve stem, and by it the stem is turned partly round to bring the
valve to its scat or to remove it therefrom. In the case of ball valves I form or fix
a transverse socket upon the valve stem to receive the ball lever, which I fasten in
the socket by means of a set screw.
I also make my seatings or valvo of metal, fibre, ebonite, leather, lead, or white
composition, whether as a loose jumper or valve attached to spindle, or used as an
insertion in any apparatus that inay be used for purposes for which this Patent is
adapted and of practical use.

PROVEMENTS IN COCKS OR VALVES AND APPARATUS FOR DRAWING OFF REGULATED
QUANTITIES OF LIQUID."
This Invention has for its object improvements in cocks or valves and apparatus
for drawing off regulated quantities of liquid.
The shell or body of the cock or valve is formed with a transverse passage
through it, in which passage there is a partition or diaphragm with a seating for a
valve closing a water way through it. The inlet for the supply is immediately
beneath the partition or diaphragm, and the outlet is immediately above it. So far
the arrangement is similar to that described in my Provisional Specification, No.
5276, in the year 1878.
I now form a cylindrical chamber over the partition or diaphragmn; it is closed
by a cover at the top having on it a stuffing box, through which the stem of the
valve passes.
The valve stem has a cupped leather fixed upon it fitting the cylin-
drical chamber, or preferably an inner cylinder or lining attached to the cover.
These parts together with a coiled spring surrounding the stem are inserted from the
top into the chamber when the cover is removed, and the valve is then fixed on to
the lower end of the valve stem from the under side. The spring becomes com-
pressed between the partition or diaphragm and a collar upon the valve stem, and it
tends to hold the valve to its seat.
When the valve has been inserted the transverse passage is closed at its lower
end by inserting a screw plug. There is a small perforation for allowing the escape
of air from the part of the cylindrical chamber over the cup leather, and the size of
this aperture can be adjusted by means of a screw with a coned end.
To draw water the valve is pressed down by a lever so as to remove the valvo
from its seat; at the same time the cupped leather is moved down within the
cylindrical chamber, the air beneath it passing freely to the upper side. The cup
leather howover prevents the air returning, so that the valve cannot close until the
air has escaped by the regulated aperture provided for the purpose.
According to another part of my Invention, where it is desired to open and close
valve cocks by means of a lever or handle making a partial rotation, I fix to the
stem of the valve a cap overhanging and surrounding the stuffing box, through
which the valve stem passes. I form an inclined slot in the side of the cap, and fix
in the part of the body or shell of the cock containing the stuffing box a pin
projecting through the slot. The lever or handle is applied to the valve stem, and
by it the stem is turned partly round to bring the valve to its seat or remove it
therefrom.
The arrangement may be varied by forming the inclined groove in the valve
spindle, and providing to engage with it a small pin or tooth formed in a piece or
ring which is placed and held between the flanges of the valve cock.
In order that my said Invention may be most fully understood and readily carried
into effect, I will proceed to describe the Drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a section of a valve cock constructed according to my Invention, and
adapted for drawing off a regulated quantity of liquid whenever the lever is mo-
mentarily depressed. a, a, is the shell or body, with the partition or diaphragm a' ;
b is the valve fitting to the water way in the diaphragmn; c is the plug which closes
the opening left for the insertion of the valve; d is the valve spindle, and e the

page_text: entering within the transverse passage through the shell or body; it is fixed to the
cover g, and the stem d of the valve b passes through it by a stuffing box at either
end, so that it may work fluid tight; i is a lever to be operated on momentarily in
any convenient manner when it is desired to draw off a regulated quantity of water;
k is a cup leather fixed upon the valve stem d within the cylinder f, and 1 is a small
passage capable of regulation by a screw plug connecting the two ends of the
cylinder f. The action has already been explained. When the lever i is for a
moment depressed the valve opens, the air in the cylinder f being able freely to pass
the cup leather in this direction, but as the cup leather prevents the air returning,
the valve cannot close until the air has had time to find its way back by the narrow
passage. The cylinder ƒ may if desired be filled with liquid.
Figures 2, 3, and 4 show valve cocks constructed according to the second part of
my Invention. In these Figures the valve spindle has a cap a mounted on its outer
end, which envelopes the stuffing box through which the valve stem passes; the cap
has an inclined slot formed in its side at a', and a pin 6 is inserted through the slot
and is screwed firmly into the shell or body of the cock at the part where the stuffing
box is formed.
On turning the cap the valve is removed from or drawn towards its seat.
Figures 5 and 6 show the modification in the arrangement according to which the
inclined slot or groove is formed in the spindle, and the pin or tooth is formed in a
separate piece or ring held between the cover and the flange formed around the
upper part of the transverse opening in the shell or body. a is the groove in the
valve spindle, and b is the piece or ring held between the flanges, and having a pin
or tooth projecting in to the groove in the spindle.
I make my seatings or valve of metal, fibre, ebonite, leather, lead, or white compo-
sition, whether as a loose jumper or valve attached to spindle, or used as an insertion
in any apparatus that may be used for purposes for which this Patent is adapted and
of practical use.
Having thus described the nature of my said Invention, and the manner of
performing the same, I would have it understood that I claim,-
First. The construction of a cock, valve, or apparatus for drawing off regulated
quantities of liquid with a piston upon the stem of the valve working within a
regulating cylinder or chamber contained within the shell or body of the cock or
valve, substantially as described in respect to Figure 1.
Second. The construction of valve cocks with a cap upon the spindle of the valve
having an inclined slot in its side engaging with a pin or stud fixed in the body
or shell of the valve cock, substantially as described in respect to Figures 2, 3,
and 4.
Third. The construction of valve cocks with a grooved spindle engaging with a
pin or tooth on a piece or ring held fast between the body or shell and the cover,
substantially as described in respect to Figures 5 and 6.
Fourth. My improvements substantially as described and represented in the
annexed Drawings.
In witness whereof, I, the said Robert Greenwood Warner, have hereunto set
my hand and seal, this Fourteenth day of July, in the year of our Lord One
