page_text: LETTERS PATENT to William Lukyn the elder, of Broad Street, in
the City of Nottingham, Dentist, for the Invention of "A LIQUID
DRAUGHT DETECTOR OR SELF-MEASURING TUBE, WITH A UNION CON--
VEYANCE TAP AND ITS STOCK AND TIME TABLE."
Sealed the 16th April 1853, and dated the 21st October 1852.
PROVISIONAL SPECIFICATION left by the said William Lukyn at
the Office of the Commissioners of Patents, with his Petition, on
the 21st October 1852.
I, WILLIAM LUKYN (the elder), of Broad Street, in the City of
Nottingham, Dentist, do hereby declare the nature of the said Inven-
tion for "A LIQUID DRAUGHT DETECTOR OR SELF-MEASURING TUBE, WITH A
UNION CONVEYANCE TAP AND ITS STOCK & TIME TABLE," to be as follows:
In the first place, I take two stop taps in one shank with keys, one
end of which may be inserted into any vessel containing liquids. At
the opposite end, about a quarter of an inch from the extremity, is
a flange cast with the tap or solder'd thereto. A washer is attach'd
within its circumference to prevent leakage, and holes are drill'd in

page_text: contact with another flange to connect it with a bib tap. The stop tap
is thus formed & connected with the bib tap at A: [see Plate 1, of
Drawings.]

shank; D, D, stop taps & keys; E, E, the holes to correspond with
the opposing flange, to screw them together at G, G; +, a stop tap
& key fixed in a cap, and solder'd on the shank of the tap, or cast with
the tap. The external part of the tube is tap'd to receive a stout glass
tube with its screw socket, & in the shank is an opening to let liquids
pass into the column.

These taps, the stop tap & bib tap, will when united appear thus.
The socket on the flange being added to receive the guaging rod with
thumb screws to regulate its length.
[See Plate 3, of Drawings.]
I cannot set forth any dimensions, as there application may vary
from large quantities to drops of liquid.
Having connected the stop & bib tap, I take one or more strong
glass or transparent hollow tube or column, having a socket screw at
one end to pass over the socket screw attach'd to the shank of the tap
at K, (Pl. 2). The socket screw is attach'd to the glass by luting,
plaster of Paris, or other well-known methods.
At the other or upper
end is a bib tap & key to let out fix'd air or fermented liquors, &c.

page_text: The stop tap at L, (Pl. 2,) is connected with this tube. The tube
should be higher than the cask or vessel containing liquids.

shank of the tap at K, (Pl. 2).
0, 0, 0, the upright glass tube or hollow transparent column. The
black shade shews where the liquor may pass. The tube may be
made of any dimensions, either for large or small quantities, & in any
number of tubes, by being attach'd to each other by socket screws, &
consequently may be carried (when supported) to any height.
P, P, the stop tap & key. The stop tap has an opening to let the
liquid pass xo, and has a screw socket to attach it to the column x x.
The tube 0, 0, 0, may be graduated on the glass to any scale of
measurement, or may be left plain, & the scale graduated on a rod,
as follows. There may likewise be inserted another stop tap on the
column at +, that the column or tube may be removed with its
contents, as a sample of the bulk.
[See Plate 5, of Drawings.]
The upright rod, Plate 5, is of wood, metal, glass, or other material,
as long as the hollow column or tube, & may be made flat, or with 2,
3, 4, or more sides, shewing different admeasurements or devices or
characters, as may be required, and is connected with the tube by a
socket attached to the flange, & passes thro' an opening on the shaft,
& has a stop screw to regulate its height upon the flange, Plate 3.
(For the shaft, see T, on the dial plate.)
"
For example, an exciseman's guaging rod with Gunthers' scale will
convey an idea of the use of the upright rod.
No. 1, the socket attach'd to the flange, to regulate the rod by a
thumb screw (Plate 5).
[See Plate 6, of Drawings.]
The base of the stand, made of iron or other material, of sufficient
weight at the base to balance the stock & time table plates.
N, N, the foot or base of the stand.
0, 0, 0, 0, the upright pillar, with a screw at the bottom to fix into
he foot or base of the stand.

Q, Q, the sliding socket exactly adapted to the pillar, with thumb
screws to stop the socket in any part of the pillar.
R, R, thumb screws.
S, a projecting socket to receive a flat bolt attach'd to the time &
stock table, with a thumb screw to secure it firm.
T, the thumb screw, Plate 6.
The parts thus united constitute the self-measuring tube, & the union
conveyance tap, & the measuring rod, & the moveable stock & time
table on its stand.
See the other side [Plate 7, of Drawings].
This plate has a bolt at the back, which drops into a socket that
passes over the upright of the stand, and slides up & down, and is
regulated by the stop screw (Pl. 7,) V.
It has six seperate plates, each of a different circumference, which
work upon a spindle from its centre, and has a shaft shewing quantity,
days of the month, months, days of the week, & hours & minutes, as
follows:-
No. 1, is a circular plate of the largest circumference, with a fix'd
spindle in the centre. Attached to the shaft are thumb screws, which
fix the plates in rotation at any given quantity of gallons, with the
minute, hour, and dates in one line.
No. 2, is the small dial plate, with its moveable hand, and with its
stop screw U, acting on the plate, for quarts, pints, half pints, quarter
& half quarter pint, each quart being divided into sixteen parts.
There are two holes in the shaft T, the round one for the glass tube to
pass through, and the square one for the measuring rod. The shaft
represent where the stop screws are placed.
The method of using the stock & time table is thus:-Having
placed the shaft in a direct line with the liquid that has risen up the
tube, turn the outer thumb screw on the shaft to prevent its moving;
then look to the measuring rod on the same line, & whatever number
of gallons it shews,-if 60 gallons, for instance,-bring the first
revolving plate to that number, which make fast by the thumb screw;
then revolve or turn the day of the mouth plate to the day wanted, s
which make fast in the same way; then the month by the same means;

page_text: then the day of the week in like manner; then the hour and minute in
the same way. Then for quarts (Pl. 7, No. 2), pints, half pint, quarter
pint, & half quarter pint, place the small hand on the number required,
and as each quart is divided into sixteen parts, you will have a close
measurement of the quantity, with the day of the month, the month,
day of the week, hour, and minute, at one glance.
These tables may be constructed on the same principle for brewers,
wine merchants, distillers, chemists, vinegar merchants, & a variety of
other trades.
THE USE OF THE SEPERATE PARTS.
No. 1, stop tap, is to keep these taps in casks to be ready at any time
to screw on the glass columa or tube, &, by the aid of a graduated
rod, to ascertain the quantity in a few seconds.
The use of the three taps:-One is to let the liquor into the tube;
the other to let it run from the tube; and the tap in the column is to
unscrew the column, & secure the liquid in the tube.
No. 2. The use of No. 2, bib tap is to attach it to No. 1, at the
flanges, & to use it to draw off the liquid when required, & by the
aid of the graduated rod & glass tube will be a much quicker and
more exact method, with less waste, than by measured vessels, and show
the quantity drawn off, and the stock left.
No. 3, the two taps united to form one tap.
No. 4, a graduated or plain glass or transparent tube, is for liquids
to rise to its level from another bulk, upon the well-known principle
that liquids meet their level. The taps & keys secures the liquid in
the tube, and may be removed.
No. 5, a guaging rod.
No. 6, a common upright stand, with a handle at top to screw off,
and a sliding socket on its pillar to receive the stock & time table,
with its stop screw & sliding socket.
No. 7, the apparatus united. Its uses set forth in the seperate parts.
Having set forth the use of the seperate parts, I will now state their
application, which is,―
To shew if leakage or other deficiency exists in casks or other vessels:
To shew what has been taken from stock in the charge of assistants

page_text: in taverns, spirit stores, public houses, & places of resort; & for the
detection of fraud:
A much quicker method of ascertaining the quantity of liquid in
vessels, &c.:
A better method of filling by measurement from one vessel to another:
A stock & time table.
The liquid in the tube will be the sample to detect adulteration in
the bulk.
By the aid of tubes connected by socket screws water may rise to any
height, to ascertain the altitude from whence running streams receive
their sourse, for the use of the army & navy, & others, in the colonies
and other parts.
In setting forth the particulars of the Invention in this Provisional
Specification it is my intention to make it more applicable & portable
in the Complete Specification; the stand, the upright column, the
guaging rod, and any other part capable of effecting it, by telescope
sockets, & joint sockets, and union joints. Nor do I confine myself
to produce the Invention in metal, as glass & other substances may in
some cases be used for acids, essential & other oils, essences, tinctures,
and other liquids. Nor can I say that it will not require a vent from
the large bulk to cause the liquid to rise in the small tube, in some
cases, by a moveable joint vent, thus: [see Plate 8, of Drawings.]
A, a pivot at one end, & a close plate at the other, B, for the slide
to pass under it; to be made air-tight by a washer & thumb screw (C),
Plate 8.
Nor do I confine myself to the upright tube being made entirely of
glass, as metal & other substances may be used, or a piece of flat
glass graduated might be formed to slide down a tin or other
receive it, to answer the same purpose, & lessen the expence, & in some
cases a flexible tube would be more applicable.

The novelty of invention I claim is in the union conveyance tap with
tubes attach'd, & in the time & stock table.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Lukyn in the Great Seal Patent Office
on the 19th April 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,.
WILLIAM LUKYN, of Broad Street, Nottingham, Nottinghamshire,
Dentist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of October, in the
year of our Lord One thousand eight hundred and fifty-two, in the six-
teenth year of Her reign, did, for Herself, Her heirs and successors, give.
and grant unto me, the said William Lukyn, Her special licence that
I, tho said William Lukyn, my executors, administrators, and assigns,
or such others as I, the said William Lukyn, my executors, adminis-
trators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel'
Islands, and Isle of Man, an Invention for "A LIQUID DRAUGHT
DETECTOR OR SELF-MEASURING TUBE, WITH A UNION CONVEYANCE TAP AND
ITS STOCK AND TIME TABLE," upon the condition (amongst others) that I,
the said William Lukyn, by an instrument in writing under my hand
and seal, should particularly describe and ascertain the nature of the
said Invention, and in what imanner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
.
NOW KNOW YE, that I, the said William Lukyn, in compliance
with the said proviso, do hereby declare the nature of my said Invention,
and in what manner the same is to be performed, to be particularly de-
scribed and ascertained in and by the following statement (that is to say):
I take two stop taps and key in one shank, and seperate the barrel
& bib from the shank. About a quarter of an inch from the extremity
of the shank is a flange, cast with the tap, or solder'd thereto; a washer
is attached to prevent leakage, and holes are drill'd in contact with

page_text: another flange to connect it with the bib tap; the shank is thus
formed.
Fig. 1 A, the channel to pass into the bib tap; this channel may be
made flush, as here represented, or ending in the shape of a conc to
pass into the shank of the bib tap; B, B, two flanges. Fig. 1a: B, B,
one flange to attach to the shank at a, either by soldering thereto, or
cast with the tap, or to screw to the shank, as here represented; the
other flange is to attach to the bib tap in like manner at G, G, Fig. 2.
C, C, C, the shank of the tap; D, D, stop taps and keys; E, E, the
holes to correspond with the opposing flange to screw them together
at G, G, Fig. 2. One side the holes are thoroughfare, and the other
side tap'd. There is a screw or chased nose, to which a hose may be
attached to convey liquids into casks or other vessels. b, a flange
to support the tap. c, c, the opening into the shank to admit the
fluid to the measuring tubes when attached by the male & female
.screw (d, omitted); e, the socket to receive the guaging rod; f, a
screw socket; g, a screw socket; h, h, the reservoir. This channel
forms part of the union conveyance tap; the shank being divided
into two channels, commencing about one eight of an inch from the
first stop tap nearest the barrel or vessel, and ending about one eight
of an inch from the second stop tap; one channel for supplying the
reservoir or chamber to supply the liquid draught detector, and the
other the channel to supply the conveyance tap for draught; this is
effected by being cast with the tap, or by a division of the shank
into two parts, and by soldering a thin plate to divide the shank
into two equal channels, and with a semi-circular plate solder'd at
the end next the second stop tap, or that which is nearest to the bib
tap, so the reservoir or chamber may be fill'd with liquid when pass-
ing thro' the shank of the tap, see Fig. 3. In the formation of the
channels in the internal shank of the tap I find in practise the plan
herein set forth is best adapted for small taps, from the sixteenth of an
inch bore to three eights of an inch bore; but where the bore of the
shank is large, say from ths of an inch to three inches or more, I
have it east with an internal shank of half the diameter of the outer
for supplying the bib tap with a circular flange at the end nearest tho

page_text: bib, to form the chamber or reservoir for the supply of the self-
measuring tube or tubes.

let the liquid pass; G, G, the flange, with a washer to screw at the
flange B, B; H, the shaft of the tap; I, the stop tap. The opening
or passage into the upright tube may be from the shank attach'd
to the bib tap; but in manufacturing the apparatus it is better to
attach the stop taps to the same shank, as shown in the accompanying
Drawing.
Fig. 3, represents the internal chamber or reservoir; the liquid
taking two courses, one to supply the measuring tube, and the other
to supply or pass through to the bib tap. A, A, A, the chamber or
reservoir for the measuring tube; B, B, the plates, solder'd or cast in

removed to attach another measuring tube to the same shank; H, a
small measuring tube for use when the liquor falls below the upright
shank on the large tube. The shank shewn in Fig. 1, may be made
with a conical end to insert into the bib tap; this form may be
used, if desired, with the flanges, or the common form of the tap

page_text: may be used, as herein set forth. I, I, the measuring rod; J, J, the
stop taps.

tube; E, F, G, II, I, semi-circular cylinders; J, the union joint. These
cylinders may be encreased to any required number for the measurement
or height of the level of liquids. The cylinders and tubes may be
graduated to any scale. The length of the cylinders mary vary to the
convenience of their application. K, the short measuring tube, to shew
the liquid when it falls below the last cylinder, & is supplied by a
branch pipe. L, the branch pipe.
Fig. 18, the small measuring tube to shew when the liquid

page_text: falls below the upright shank of the large measuring tube; see
Fig. 5.
Fig. 14, stock & time table. This table has six seperate plates; or
a larger or lesser number may be. used. In the Provisional Specifica-.
tion I have stated my stock & time table consists of six seperate
plates, each of a different circumference, which work upon a fixed
spindle from its centre, and has a moveable shaft shewing quantity,
days of the month, days of the week, and hours and minutes. (These
plates may be engraved, cast, painted, or otherwise set forth on the
plates.) No. 1, is a circular plate of the largest circumference, with a
fix'd spindle in the centre; attach'd to the shaft are thumb screws,
which fix the plates in rotation at any given quantity of gallons,
with the minute, hour, and date in one line. No. 2, is the small dial
plate with its moveable hand, and with its stop screw acting on the
plate for quarts, pints, half pints, quarter pint, and half quarter pint;
there are two sockets in the shaft, the round one for the glass tube to
pass through, and the square one for the measuring rod: The holes in
the shaft represent the stop screws.
The diameter of the plates is not
material, but they may be made large or small, as may be required.
The method of using these tables is thus:Having placed the shaft in
a direct line with the liquid that has arisen up t the tube, turn the
thumb screw on the shaft to prevent its moving, then look to the
measuring rod on the same line, and whatever number of gallons it
shews, if 60 gallons, for instance,-bring the first revolving plate to
that number, which make fast by the thumb screw. Then revolve.
or turn the day of the month plate to the day wanted, which make
fast in the same way; then the month by the same means; then
the day of the week in like manner; then the hour & minute in the
same way. Then for quarts, pints, hali pints, quarter pint, & half
quarter pint, place the small hand on the number required; and as
cach quart is divided into sixteen parts, you will have a close measure-
ment of the quantity, with the days of the month, the month, day of the
week, hour, and minute, at one glance. The tables may be constructed
upon the same principle for brewers, wine merchants, distillers, chemists,
vinegar merchants, and a variety of other trades.

page_text: Fig. 15. In reconstructing the stock & time table I find it much
more portable to let each plate revolve in a sunken groove, as herein
set forth, (see the Drawing, Fig. 15 a,) the outer plate being about six
& a half inch diameter, and about one eight of an inch in thickness.
Five or more grooves are made to receive the circular plates, and the
hauds revolve upon a spindle from the centre. The set screw fixes
the hands in any required position. A, A, A, A, the outer plate, to
which the spindle is attached in its centre, and five grooves are
made into the plate to receive the revolving plates, which are made
secure by turning the edge of the grooves on the dial plate. The
plates are moved round by a pin (0, 0, 0, 0, 0,) attach'd to each plate.
B, B, B, B, the revolving plate and pin on which 108 gallons are
set forth; C, C, C, C, the revolving plate and pin on which the days
of the month are set forth; D, D, D, D, the revolving plate and
pin on which the months are set forth; E, E, E, E, the revolving
plate and pin on which the days of the week are set forth; F, F, F, F,
the revolving plate and pin on which the hours & minutes are set
forth; G, G, G, the hands, which revolve upon a tapped spindle,
having a washer between each hand; II, a female cap screw, to fix
the hands in any required position; I, I, the small dial plate for
quarts, pints, half pints, quarter pint, & half quarter pint. The
method of using these plates is to place the hand at the number of
gallons required; then by the means of the pin to revolve the plate
on which the days of the month aro set forth to the day required to
the same hand; then the required month to the same hand; then the
day of the week to the same hand; then the hour & minute to the
same hand; then secure them in their position by turning the female
tap screw upon the spindle. Several hands may be attached upon the
same spindle, indicating different kinds and quantities, which may be
ascertain'd at the same time.
Fig. 16, represents a series of stock & time tables set forth in onc
view, on metal, enamel plates, slate, carthenware, glass, or any other
suitable material, registering the various kinds of wines, spirits, and
different sorts of ale and porter in stock. These tables may be set
forth for any description of stock in trades for which they are appli-

variety of others; or may be set forth in weights & measures for
dry goods. A, A, for wines & spirits, representing gallons & aliquot
parts of a gallon, from one gallon to one hundred and twenty-six
gallons, and to the sixteenth of a quart. B, B, B, for ale & porter,
representing gallons and aliquot parts of a gallon, from one to one
hundred and cight gallons to the sixteenth of a quart; C, representing
the month and day of the month; D, representing the day of the
week and time; the long hand represents gallons, and the short hand
the aliquot parts, revolving upon the same spindle, and fixed by its
stop screw in the same way as H, Fig. 15, which sec; F, a circular
table for dry goods.
Fig. 17, is a guaging rod, of wood, metal, glass, earthenware, or
other material, as long as the hollow column or tube, and may be
made flat, or with two, three, four, or more sides, shewing different
admeasurements, or devices, or characters, as may be required, and
is connected with the tube either by a socket attached to the
flanges or to the shank, as represented, sco Fig. 5, & 14; but
being more portable, it is made in joints, or a telescope tube, see
Fig. 17 a.
Fig. 17 a, a telescope guaging rod, with coupling joints and
stuffing boxes, with one, two, or more sides for different admeasure-
ments, or devices, or characters, and for the same use as Fig. 17, but
more portable.
Fig. 18, represents the conveyance tap attached to a strong flange
of wood with iron braces, or wrought iron or any other suitable
material, with supports or props, and capable of resisting consider-
able pressure, in order to ascertain the height from whence enclosed
running streams receive their supply, whether issuing through small
channels in rocks or other apertures, or for any liquid confined in
reservoirs or any other receptacle, and for draught from the same.
The water or liquid must be well secured, and to assist to prevent
leakage a washer is fixed to the flange, and stuffing, grease, clay, or
cement is applied. Where the height is considerable, a hose with a
tube attached to the upright shank will be found to be the most

page_text: convenient for ascertaining the height, where it would be impossible
to use the tube. A, A, A, the flange & washer, with its support; B,
the aperture in the rock; C, the hose, with self-measuring tube
attach'd (see Fig. 10); D, a chased nose, to which may be attach'd
a hose to convey tho liquid from the tap into casks or other vessels
for the use of shipping or for store. The conveyance taps should be
of a large bore, from 2 or more inches, in case the draught should be
considerable.
Fig. 19, represents the vent with its chain or wire attached to the
spring lever to raise the valve.
Fig. 20, the conveyance tap with its internal chamber; see Fig. 1,
and 3.
The apparatus herein-before described may be applied to shew if
leakage or other deficiencies exists in casks or other vessels, and for
sample from the same, and to shew what has been taken from stock
in the charge of assistants in taverns, spirit stores, public houses, and
places of public resort, and for the detection of fraud; a much quicker
method of ascertaining the quantity of liquids in vessels, &c.; a better
method of filling by measurement from the tube from one vessel to
another; a stock and time table; and a method to ascertain the
probable altitude from whence confined running streams receive their
source, and for draught from the same.
Having now described the nature of my Invention, and the apparatus
and arrangements constituting the same, I wish it to be understood
that I do not claim as new or the exclusive use of any of the parts
herein-before described and represented, when taken seperately and
not employed in combination for conveying or drawing off liquids, or
for conveying liquids to or measuring the same by glass tubes.
But I claim as iny Invention a union conveyance tap, with a reservoir
or chamber in the shank of the tap, to supply one or more measuring
tubes, by which the liquid drawn off through the taps is indicated in
the tube or tubes attached to the shank of the tap communicating with
the reservoir or chamber, as herein-before described. Secondly, I
claim the application of a graduated telescope tube, with its glass tube
attach'd, to indicate the height of liquids, for its measurement when

page_text: attached to the shank of the tap communicating with its reservoir or
chamber, as herein-before described. Thirdly, I claim the construction
of stock & time tables as herein-before described.
In witness wherof, I, the said William Lukyn, have hereunto set
my hand and seal, this Nineteenth day of April, in the year
of our Lord One thousand eight hundred & fity-three.
