AN IMPROVED COCK FOR DRAWING OFF LIQUORS
Year: 1808

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
MASSEY, of Newcastle, in the County of Stafford, Clock and Watch Maker,
send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of the United Kingdom of
Great Britain and Ireland, bearing date at Westminster, the Twenty-fourth
day of September, in the forty-eighth year of His reign, give and grant unto
me, the said Edward Massey, my exors, admors, and assigns, His especial
licence, full power, sole privilege and authority, that I, the said Edward
Massey, my exors, adñiors, and assigns, during the term of years therein
mentioned, should and lawfully might make, use, exercise, and vend, within
England, Wales, and the Town of Berwick-upon-Tweed, my Invention of "AN
IMPROVED COCK FOR DRAWING OFF LIQUORS;" in which said Letters Patent there
is contained a proviso obliging me, the said Edward Massey, by an instrument
in writing under my hand and seal, to cause a particular description of the
nature of my said Invention, and in what manner the same is to be performed,
to be inrolled in His Majesty's High Court of Chancery within one calendar
month after the date of the said recited Letters Patent, as in and by the same,
relation being thereunto had, may more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Edward Massey, do hereby declare that my said Invention is described and
ascertained in and by the Drawings hereunto annexed, and the following
description thereof, that is to say :-

page_text: Fig. 1 represents a cock with three valves; the first, at A, is of the same
shape as Fig. 2, the funnel part and valve being thrown about a quarter of an
inch out of the center for the purpose of admitting the other rods to pass up
the middle. B is a stuffing box to prevent its breaking out of the top; but it
may be made with the same figure of a valve, and used without the stuffing
box, by separating the axis from the valve and making the point to press on
the center of it, as represented at c; the lever d being a fixture to the axis,
and connected with the valve by means of the forks or claws e, and the convex
spring f bearing up the axis against the shoulder 9, upon which is fitted a
leather collar to prevent leakage; but if made with stuffing box the spring
must be reversed and applied against the shouldering at g. H is the second
valve of the same shape as Fig. 2, and fixed vertically; a spring is introduced
at the back of the valve, with its convex side bearing against it at i, and its
extreme points having their bearing within the cock. The front part of the
valve is a fixture, being of the same shape as Fig. 2; the object of the spring
is to keep the valve together with a gentle pressure. Now it is evident, when
two such figures as Fig. 2 are in the same direction, the passage will be open,
and when one of them is turned a quarter of a circle by the lever or key at j,
which is connected to the valve H by the tube k, it will be closed. L, the
third valve, which is represented as open; the liquor is to pass through the
small holes at m. When the valve is shut it is drawn tight against its bearing
at n by means of the spring, Fig. 3, which is attached to the elbow in
the front of the cock, and turns on the center at o. When the valve is
required to be closed, pull it forward by the point of the rod p, and press the
spring towards the cock, and pass the opening in it over the rod, the point
of which being the largest the spring will have a tendency to pull the valve
forward in proportion to the strength of it. This rod passes through the center
of the tube k, in which there is a stuffing box at q to prevent breakage in caso
of the inner valve not being perfectly tight. There is likewise a stuffing box
in the lever at r to prevent leakage in the front of the cock, so that the liquor
may occasionally be under the security of three valves. Fig. 4 is a front view
of the lock of the cock, which, besides answering the ordinary purpose of the
locking, it also locks it to the barrel, as hereafter described. a is the lever
that turns the second valve at H in Fig. 1; b is the staple; c is the hook
acting on a center; d, the spring; c is the stop, and fits spring; at g the key
is introduced, which must be raised on its center so as to pass clear of the
work in the lock, except coming in contact with the hook and stop, which rise
a little higher than the other parts, and are opposed to the key. Now, when
the key is turned in the direction of the dotted arch, and the hook pressed out

page_text: of the staple by it, raise the lever a, and the staple being a fixture, or part of
it, it will be raised also, at which time the inner part of the staple which
presses down the ward or stop into the dotted arch being likewise raised,
the stop will rise out of the arch, and prevent the key from being, taken out
till the staple is returned into the lock, the object of which is, to prevent the
cock from being left unlocked. Fig. 5 represents a bar which is to secure
the cock to the barrel. Fig. 6 is a stud which must be made fast to the
barrel in a parallel line with the top hole, and about two inches-from-it,
which being done, the axis of the bar at a, Fig. 5, must be introduced-into-it
at a, when done introduce the the pin or screw b, which passes in a right
line through the stud and through the grove of the axis a, Fig. 5, which will
prevent its being taken out of the stud till the screw or pin.b is drawn out,
which cannot be done without violence when the cock is in the barrel. Now
when the bar is fixed, as above described, the cock must be introduced into
the barrel, the bar being at liberty to move in a horizontal direction; and tho
slide nut c, Fig. 5, being moveable along the bar, it will be easy to bring it so
as to enter a screw into the nut at b, Fig. 5, through an upright hole in the
lock at k, Fig 4, and by this means screw the lock tight to the bar. Now
the lever a covers the screw when locked, by which means it is rendered as
necessary to have the key to draw the cock out of the barrel as it is to draw
the liquor. The lock may be applied to an horizontal valve, such as at a, Fig. 1,
as conveniently as it is to the vertical one, but in that case perhaps it may
be full as convenient to fix the bar vertically, and made as represented in
Fig. 7. The nut or stud, Fig. 8, is secured to the front of the plate, Fig. 4,
at about i, but is moveable horizontally on its center, so as to form a line with
the bar. But the lock is not now represented as having tho plate attached to
it, as in that case it would not shew the inner parts of it. The stud, Fig. 6,
must likewise be fixed vertically about an inch above the tap hole, so as the
pin or screw cannot be taken out when the cock is in the barrel. Now the
screw must be passed through the groove in the bar into the nut or stud
Fig. 8, and screwed tight to it. The lever in this case must have a projection,
so as to cover the head of the screw when locked, which will prevent the
cock from being drawn, as before described, when placed vertically.
Having described the method of making a cock with three valves, and a
method of locking it to the barrel, be it observed that it is not necessary
that all the valves should be used in the same cock, but may be made with
one, two, or three valves, just as the mechanic or purchasor may think.
proper. If it is wished to use the inner valve 1, Fig. 1, horizontally, as
at a, it will require the stuffing box b, but no spring or shouldering to the

page_text: rod, as in this case the valve must be drawn upward, but may have a lever
fixed on an upright as at a, Fig. 9, to turn over the top of it when closed,
which will likewise answer to lock it, as before described, in using the lock
horizontally. If it is wished to use the valve, Fig. 2, for an inner valve, it may
be applied as represented in Fig. 10, with a spring at a. Again, if the valve 7,
Fig. 1, be used singly, it may be flung back by a crank, as at a, Fig. 11, but
the axis should be flung out of the center, so that the crank may act as near
the middle as possible, and when closed, the crank being turned, the spring b
will catch in the nick, as represented at Fig. 12, and have a tendency to pull
the valve forward. The valve, Fig. 13, may be substituted instead of Fig. 2,
and the valve Fig. 2 may be used without the rim, whichever experience may
point out as most advantageous, or they may be fixed obliquely, as in Fig. 14,
but in all the above-described methods the liquor will have a tendency to close
the valves.
In witness whereof, I, the said Edward Massey, have hereunto set my
hand and seal, this Twenty-fourth day of October, in the year of
our Lord One thousand eight hundred and eight
