PROVISIONAL SPECIFICATION.
Improvements in Appliances for Discharging Liquids from Casks
and other Receptacles.
We JAMES CARTER of Atlas Works, Stalybridge, in the County of Chester,
Brass and Iron Founder; and ELIJAH JAMES GRANTHAM, of No. 19 Kenworthy
Street, Stalybridge in the County of Chester, Foreman, do hereby declare the
nature of this invention to be as follows :-
Our said invention relates to improved devices for facilitating the withdrawal
of liquids from casks and other receptacles, and consists of a valve seating
intended to be secured to the receptacle, in which works a sliding valve provided
with a spring, so arranged that the normal position of the valve prevents the
egress of the contents of the receptacle. For opening the valve we provide a
hollow nozzle, the end of which takes into or against the outer end of the valve,
and which when pushed into the valve seating opens the valve and allows the
liquid to pass out through the interior of the nozzle.
In the valve seating, or the casing in which the same. is formed, we provide one
or more grooves the ends of which are formed with inclines in the manner of a
screw thread. Into the said grooves take one or more corresponding projections
on the outside of the nozzle. After the nozzle has been pushed in it is turned
on its axis by means of lugs provided for that purpose; the projections before
mentioned then bind against the inclined grooves and while retaining the nozzle
in its place keep the valve open. On the nozzle is an indiarubber ring or washer.
which, when the nozzle is secured in its place as above described, fits into a
recess in the casing carrying the valve and thus makes a liquid proof joint.
To prevent the valve from being tampered with before the nozzle is inserted,
we provide a projecting cap which is screwed on to the outer face of the valve
casing, and is provided with a socket to receive a suitable key for turning the
projecting cap.
The outer end of the nozzle may either be a plain tube arranged to be
connected to another tube or pipe, through which the contents of the receptacle
may be pumped or otherwise discharged, or it may be provided with a tap or stop-
cock, through which the contents of the receptacle may be drawn off in the usual
manner.
In some cases as for instance where the contents of the receptacle are required
to be pumped from the upper end we provide a lengthening piece or prolongation,
which fitting on to the inner end of the valve casing extends downwards to the
bottom of the receptacle. In such case a foot valve is provided in order that a
small quantity of the liquid may be retained at the top for the purpose of
priming the pump. In a modified arrangement of our said invention, the said
lengthening piece is constructed in such a manner that it may be pushed right
through the valve casing from the outside.

COMPLETE. SPECIFICATION.
Improvements in Appliances for Discharging Liquids from Casks
and other Receptacles.
We JAMES CARTER of Atlas Works, Stalybridge in the County of Chester,
Brass and Iron Founder, and ELIJAH JAMES GRANTHAM, of 19 Kenworthy
Street, Stalybridge, in the County of Chester, Foreman, 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 :-
Our said invention relates to improved devices for facilitating the withdrawal of
liquids from casks and other receptacles, and consists of a valve seating intended to
be secured to the receptacle, in which works a sliding valve provided with a spring,
so arranged that the normal position of the valve prevents the egress of the contents
of the receptacle.
.:.
For opening the valve we provide a hollow nozzle the end of which takes into or
against the outer end of the valve, and which when pushed into the valve seating
opens the valve and allows the liquid to pass out through the interior of the
nozzle.
In the valve seating, or the casing in which the same is formed, we provide one
or more grooves the ends of which are formed with inclines in the manner of a screw
thread. Into the said grooves take one or more corresponding projections on the
outside of the nozzle. After the nozzle has been pushed in it is turned on its axis
by means of lugs provided for that purpose. The projections before mentioned
then bind against the inclined grooves and while retaining the nozzle in its place
keep the valve open. On the nozzle is an indiarubber ring or washer which, when
the nozzle is secured in its place as above described, fits into a recess in the casing
carrying the valve and thus makes a liquid proof joint.
To prevent the valve from being tampered with before the nozzle is inserted we
provide a projecting cap which is screwed on to the outer face of the valve casing,
and is provided with a socket to receive a suitable key for turning the projecting
cap.
The outer end of the nozzle may either be a plain tube arranged to be connected
to another tube or pipe, through which the contents of the receptacle may be
pumped or otherwise discharged, or it may be provided with a tap or stop cock,
through which the contents of the receptacle may be drawn off in the usual manner,
and in one modification of our said invention a sliding spring rod is used for opening
the valve..
In some cases as for instance where the contents of the receptacle are required
to be pumped from the upper end we provide a lengthening piece or prolongation,
which, fitting on to the inner end of the valve casing extends downwards to the
bottom of the receptacle. In such case a foot valve is provided in order that a
small quantity of the liquid may be retained at the top for the purpose of priming
the pump. In a modified arrangement of our said invention the said lengthening
piece is constructed in such a manner that it may be pushed right through the
valve casing from the outside.
Referring to the accompanying drawings which illustrate our said invention
Figures I and IV show a longitudinal cross section and a front view of one form of
an appliance made in accordance with our said invention.
Into the bush a which is permanently attached to the barrel or cask is screwed
the valve box b. An indinrubber ring 6' intervening between the front flange of
the valve box and the face of the bush a makes a liquid proof joint.
perforated sieve box c is attached to the valve box 6 where it projects into the
interior of the barrel.
A
The valve d sliding in the casing or valve box b is preferably provided with
an indiarubber joint ring d¹ making joint against the flat face of the end of the
:
:

page_text: valve box. The tube of the valve d is perforated so that when pushed inwards
the liquid in the barrel may pass through the said perforations and along the
tube. A spring d bearing at one end against the valve box 6 and at the other
end against a collar on the valve d keeps the valve normally closed. e is the
hollow nozzle hereinbefore referred to provided with lngs el el by means of
which it may be grasped and also with a stud or projection e³ which takes into
a grooved in the valve box d shown in sectional plan in Figure II and in a
transverse section through x-y of Figure II in Figure III. As will be seen
from the drawing the groove d' is straight for a certain distance and then
follows an inclined direction forming part of a short spiral in the interior of the
valve box. The nozzle e having been inserted is first pushed straight_inwards
until the stud e reaches the end of the straight part of the groove d³. It is
then twisted when the stud e binds against the spiral groove and keeps the valve
open. is the external joint ring or washer taking into the recess in the front
of the valve box as hereinbefore referred to.
.
Figure V shows a modification of our said invention used in combination with a
bib or bent outlet f formed on the nozzle pipe g which is screwed on the valve
box b. An indiarubber joint ring being interposed to make a tight joint. In
this modification the locking stud and groove are not used. The inner pipe / is
perforated and when pushed against the valve by the knob p¹ the valve will open
and the liquid will pass from the interior of the valve along the pipe / and through
the perforations therein. A spiral spring h* bearing against the knob keeps the
pipe normally withdrawn from the valve. The tail rod A³ works in a suitable
gland packed with an indiarubber washer.
A safety cap, Figures VI and VII, having an indiarubber packing ring, is
provided to screw on the valve box 6 when the valve is not in use. The said cap
is provided with a square, half round or other suitably shaped key block so that
only a person possessing a corresponding key can remove the safety cap.
In Figure VIII is shown the hereinbefore mentioned lengthening piece for
emptying a barrel from the upper end. The upper chamber of the said lengthening
piece screws on to the valve box b in the interior of the barrel and the tube 1 of
a length to suit the barrel to which it is to be applied extends downwards to the
bottom. is the foot valve hereinbefore referred to.
The said lengthening piece is passed through the bush a of Figure I and is held
in position when the valve box 6 is screwed home and is withdrawn when the
valve box 6 is removed.
It is to be understood that I do not limit myself to the precise details of the
constructions or forms shown as they may be varied to suit special applications
and in cases where the invention is used for liquids which have a deleterious
effect on indiarubber other well known methods of making liquid proof joints
may be employed.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is-
I. The herein before described combination of a hollow sliding valve opened by
a sliding hollow nozzle with the means for locking the same when open sub-
stantially as and for the purpose herein before set forth with reference to
Figures I, II, III and IV of the accompanying drawing.
II. The hereinbefore described combination of a hollow sliding valve opened
by a hollow nozzle sliding in a discharging pipe attached to the valve box
substantially as and for the purpose hereinbefore set forth with reference to
Figure V.
III. In combination with devices such as referred to in Claims I and II the
use of a safety cap as shown in Figures VI and VII substantially as set
forth.
IV. In combination with the device referred to in Claim I the use of the

page_text: lengthening piece hereinbefore described with reference to Figure VIII substan-
tially as and for the purpose set forth.
Dated this 23rd day of June 1892.
