page_text: NOW KNOW YE, that in compliance with the said proviso I, the said
Thomas Arnold, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, is herein set forth and
explained, reference being made to the Drawing hereunto annexed :-
My improved machine or gauge is so contrived that it will correctly register
the quantity of spirits or other fluid that may be drawn from any receptacle,
and the strength of any spirituous liquors may also be ascertained while it is
being drawn from the vessel or receptacle, should it be required. Figure 1
represents a plan of the principal parts of one of my improved machines or
gauges, the cover, which is to be kept locked down, being removed in order to
shew the internal construction more clearly. Figure 2 is a vertical section,
made by a plane passing through the dotted line a, b, in Figure 1. Figure 3
is a vertical section at right angles to Figure 2, taken in the direction of the
dotted line c, d, see Figure 1. Figure 1,.A. is a cock fixed to the frame of
the machine; the back end has a male screw to which a pipe can be attached,
leading from the receptacle containing the liquor to be drawn off and regis-
tered; B is a measuring wheel, containing three chambers, e, f, g; the internal
.capacity of each is such that it will hold exactly half a quartern, and whenever
that precise quantity has run into it from the cock A the wheel B immediately
-performs one-third of a revolution, and empties its contents into the case of the
machine, from whence it runs into the reservoir C; the wheel is then detained
in its position until another chamber is filled, when a similar effect will be pro-
duced, each quantity being duly registered to the amount of one thousand
gallons. The apparatus that detains the measuring wheel after each motion,
and the means used for denoting or registering the quantities drawn off, will be
explained hereafter. Ċ is a cylindrical reservoir, made to hold rather more
than one pint of any liquor; D is a globular glass float placed in the reservoir C;
h is an iron wire stem fixed to the float by a cork through which it passes.
The cork fits tight in the neck of the float, by which means it may be adjusted so
as to place the float at any convenient depth, where it must be fixed with sealing
wax or any proper cement. The upper end of the stem is jointed to one end of
the brass arm i; the other end of the arm has a square hole through it, which
fits upon the squared end of the valve of the cock A, therefore, when the float
rises or falls, it will raise or lower the arm i, and open or close the valve accord-
ingly; is a bar having a hole in its centre, through which the stem h passes,
and moves in it freely up or down, the bar acting as a guide when the stem
is in motion. Just above this bar a small piece of tin is soldered to the stem ;
this rests upon the bar k at certain times, and supports the weight of the float
at a proper distance below the cock A, forming also the means for adjustment,
"

page_text: which is effected by bending the pointed ends of the tin bearer. E is a cock
fixed to 'the lower conical end of the reservoir C, but in reality it represents
the one usually placed, at the bar of a liquor shop; whatever quantity of
liquor passes through this will be duly registered by the means now to be
described. The measuring wheel is made to turn freely upon the two
pivots of its axis. The bearing of one of one of the pivots is seen at.
in Figures 1 and 3; the other bearing is fixed on the outside of the
case, where it may be seen in Figure 4 at m, and also detached in Figure 5.
One end of the axis t projects in front of the machine beyond the front pivot
to receive a cam wheel n, Figure 4, and also a brass pinion o, having twelve
teeth; p is a stop latch; one end is jointed by a screw to the frame g; the-
centre part is bent so as to fit and take a bearing on the flat parts of the
cam wheel, and thereby retain it stationary, the necessary pressure upon it:
being effected by the spring when adjusted by the screw 8. When the
measuring wheel moves one-third part of a revolution it causes the cam wheel n.
to lift the stop latch to the position shewn in Figure 4, and at the instant the
contents of the chamber is emptied the latch p will, drop and retain the wheel,
stationary until another chamber is filled, and then the same effects will be:
produced.
Figure 5, t, shews a plan of the axis of the measuring wheel'n and pinion a
fixed to one end of it; in this Figure the pivots of the axis will be plainly seen.
Figure 8 represents a plan of two cocks that are fixed to the lower part of
the reservoir C; the one at E is used to draw off the liquor from the reservoir,.
and that seen at F may be opened, when the spirits contained in the reservoir C.
will rise in the glass vessel G, and the strength may be ascertained by an
hydrometer in the usual manner. The glass vessel G,is cemented into the
conical metal base H by any suitable kind of cement that will make a water
tight joint. When the strength of the spirit has been ascertained; tlie hydro-
meter should be taken out, and the cover I put on, by which means the glass.
vessel will be kept clean and always ready for use. The cock shewn at the.
bottom of the glass vessel G, Figure 3, is used to empty that vessel, the..
cock F, Figure 8, being previously.closed.
Figure 6 represents the frame containing the train of wheels and pinions
combined so as to indicate upon the dial plate, seen at Figure 7, the number of
gallons drawn to the extent of one thousand down to any quantity not less than.
half a quartern. For this purpose there are five circles of figures upon the
dial. The first, c, denotes half quarterns; the second, f, pints; the third, k,.
gallons; the fourth, o, tens of gallons; and the fifth r, hundreds of gallons.
The back plate of the frame in Figure 6 is removed in order to shew.

page_text: the train of wheels and pinions, which are combined in the following
manner; that is to say, Figure 4, geers into the teeth of 6, Figure 6,
and so on in the order of the letters placed alphabetically on each
wheel and pinion, the number of teeth being also marked 'üpon each, by
which means the numbers of the train-may be seen by a bare inspection;
the wheels. lettered:0,"¨k, r, e, f, being those that have a lengthened arbor passing
through the said plate to 'fix' hands upon, as seen in Figure 7: An edge view
of the frame and train of-wheels," 'complete and combined with the machine,
may be seen in Figure 1.
Par
Figures 1, 2,. 3, 5, and 8. are drawn to a scale two-thirds the real" size,”
but the Figures 4, 6, and 7 are drawn the real size of the objects: they!
represent: The chambers of the measuring wheel may be made of various
shapes; but none that I know off will answer the purpose so well as those!
I have described. Therefore, in constructing the measuring wheel," the
circular end pièces should be divided into three parts as near the circumi-
ference as may be, and three radial lines must then 'be drawn from each
division to the centre, as shewn at v, in Figure 2: In the centre of each line
the compasses must be placed, and a semicircle described from the points on
each line, touching the centre and likewise the circumference of the ends, and
the arc so described will be the true shape of each chamber, it being absolutely
necessary that each should be of such a form that when the wheel moves
one-third of a revolution, the chamber that descends should empty. itself
instantaneously, which it may be seen will be the case if the chamber
examined in Figure 2.

In Figure 4, a spring is shewn as the means of pressing upon the
latch p; but the same effect may be produced by a weight appended to the end
-of the latch, as shewn in dotted lines at u. The best position to fix this
machine in is about six inches below the receptacle, and then the cock. E should'
be placed at the bar by having a pipe of a proper length fixed to it. The
cistern or reservoir C should then be filled as high as it is shewn in Figures 2
and 3, or just high enough to raise the float so as to make it close the cock A,
after which, whenever any quantity of liquor is drawn from the cock E equal
to half a quartern; the float D will descend and open the cock A, which will fill
one of the chambers at the measuring wheel B, and then it will move and
empty itself into the reservoir C, which will cause the float to rise and close the
cock A, the train of wheels being at the same instant set in motion to register
the quantity. The external case of this machine or gauge may be made of
pewter, lead, tinned copper, or-iron, zinc, or any other suitable metal or material.
The measuring wheel should be made of tinned copper, it being desirable to

page_text: keep it as light as possible. I prefer à glass float, that substance being less
liable to change than any other; nevertheless, it may be made of tinned copper
or any other suitable metal or material that will be sufficiently buoyant, and
not liable to rapid decay. And, although I have made this machine, in point of
size, suitable for a retail liquor shop, yet it may be made of any size at the
option of the purchaser, and it will be found to answer equally well; and I shall
also observe, that although I have adopted a train of wheels that are most
suitable to the peculiar purposes of this machine, yet any other train may be
combined therewith that will be more applicable to any particular purpose to
which the gauge may be applied, the train of wheels forming no part of my
Invention. And I hereby further declare that my Invention consists, firstly, in
combining and applying a glass vessel and cocks, as herein described, to my
improved machine or guage for containing and exposing to view any sample of
spirituous liquor, the strength of which it may be desirable to ascertain by the
common hydrometer, while it is submitted to the measuring and registering
powers of my improved machine or gauge; secondly, in the construction and
application of the measuring wheel and float, and also the cistern or reservoir,
herein described, by the use of which, in the way I have explained, spirituous
liquors or fluids of any kind may be measured; and when these agents are
combined with the train of wheels herein described, the fluid, so measured, will
also be accurately registered by the self-acting properties of this improved
machine or gauge.
In witness whereof, I, the said Thomas Arnold, have hereunto set my
hand and seal, the Twenty-sixth day of November, in the year of our
Lord One thousand eight hundred and twenty-nine.
