PROVISIONAL SPECIFICATION.
An Appliance for Registering or Recording the Volume of Liquid
Passing Through a Tank or Vessel.
I, WILLIAM PATRICK BRUCE, of Kinleith Mill, Currie, in the County of
Midlothian, North Britain, Paper Manufacturer, 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:-
This invention relates to an appliance for registering or recording the volume of
liquid passing through a tank or vessel. One application of my invention is for
measuring bleaching liquid in paper making. The tank containing the bleaching
liquid is provided with a float which is attached to the end of an upright spindle
which protrudes out from the top of the tank. The upper end of the said spindle
is provided with a projecting pencil or other marking medium, the arrangement
being such that as the float rises and falls in the tank by the rising and falling of
the level of the liquid, a line or mark is made by the pencil or appliance upon a
sheet of paper placed round a drum. The tank is filled and emptied by pipes with
stop cocks so arranged that they cannot both be open at the same time. For this
purpose I prefer an ordinary 3-way cock. The key of the cock is connected to the
drun in such a way that every time it is turned to run liquid out of the tank it
revolves the marking drum sufficiently to give the pencil a fresh surface to work
upon, but does not bring the drum back again on being shut.
This may be done by leading a spindle from the key of the cock to the paper
drum. An eccentric or crank may be keyed upon the top of the spindle with a
ratchet around the bottom of the paper drum into which ratchet a pawl works
under the influence of the eccentric or crank as the spindle is given a motion of
rotation when the key of the three way cock is turned.
The result is that the pencil draws a series of lines, the length of which repre-
sents respectively the quantities of liquid that have from time to time been drawn
from the tank. There may be provided a spring or other suitable arrangement to
maintain a steady pressure of the pencil on the surface to be marked.
I do not limit myself to the precise details as they may be varied, for example
the recording paper may be fixed upon a board or other surface, instead of a drum.
Also the pencil may be in connection with the float by a chain or cord passing
over a pulley. Also the pencil markings may be enlarged or reduced by gearing
or by other means.
The registering apparatus may be enclosed in a box under lock and key.
Dated this 7th day of September 1894.

I, WILLIAM PATRICK BRUCE, of Kinleith Mills, Currie, in the County of
Midlothian, North Britain, Paper Manufacturer, 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:-
+
This invention relates to an appliance for registering or recording the volume of
liquid passing through a tank or vessel, and is applicable for various purposes,
though especially for measuring the bleaching liquid used: in paper manufacture.
But in order that my said invention may be more readily understood and easily
carried into effect I will proceed to describe the same with reference to the
accompanying drawings.
•
.
Figure 1 is a sectional elevation of a tank for bleaching liquid, having my
appliance attached.
Figure 2 is a plan of the same.
Figure 3 is a detail...
The tank containing the bleaching liquid is provided with a float B, which is
attached to the end of an upright spindle C, which protrudes out from the top of
the tank A. The upper end of the said spindle C, which works in suitable
guides c, is provided with a projecting pencil or other marking medium D, the
arrangement being such that as the float B rises and falls in the tank A by the
rising and falling of the level of the liquid, a line or mark is made by the pencil or
appliance D upon a sheet of paper placed round a drum E. The tank A is filled
and emptied by pipes F with stop cocks, so arranged that they cannot both be
open at the same time. For this purpose I prefer to employ an ordinary 3-way
cock G, (Fig. 1 and detail plan Fig. 3) the key H of which is connected to the
drum. E in such a way that every time it is turned to run liquid out of the tank A
it revolves the marking drum E sufficiently to give the pencil D a fresh surface to
work upon, but does not bring the drum E back again on being shut. This may
be done by leading a spindle J from the key H of the cock G to the paper drum E,
the upper end of which is connected to an eccentric or crank K, said crank K
being connected to a pawl L, which gears into a ratchet M formed or provided
around the bottom of the paper drum E; the said pawl L working under the
influence of the eccentric or crank K as the spindle J is given a motion of rotation
when the key H of the three way cock G is turned.
The result is that the pencil D draws a series of lines, the length of which
represents respectively the quantities of liquid that have from time to time been
drawn from the tank A. There may be provided a spring or other suitable
arrangement to maintain a steady pressure of the pencil on the surface to be
marked, and the ratchet M may be provided with a retaining catch or pawl N.
I do not limit myself to the precise details as they may be varied, for example.
the recording paper may be fixed upon a board or other surface instead of a drum..
Also the pencil may be in connection with the float.by means of a chain or cord
passing over a pulley. Also the pencil markings may be enlarged or reduced
gearing or by other means.
The registering apparatus is preferably enclosed in a box under lock and key.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
The general arrangement, construction and combination of parts constituting the

page_text: appliance for registering or recording the volume of liquid passing through a tank
or vessel, substantially as hereinbefore described and shown in the accompanying
drawings.
