in Reservoirs and the Quantity therein, and for other similar
Purposes.
We PERCIVAL WILLIAMS of 88 Shrubland Road, Dalston, in the County of
Middlesex, Electrician and, WALTER POWLES, of 278 Roman Road, Bow in the
County of Middlesex, Electrician, do hereby declare the nature of this invention
to be as follows
-
The object of our invention is to provide simple and efficient apparatus for
electrically indicating by one wire the capacities and heights of Gasholders, the
rise & fall and quantity of Water in Reservoirs, or the like purposes, we will now
describe our invention.
The Sending or Transmitting Instrument, In a suitable case is contained a shaft,-
which projects from the case, and has a wheel or pulley, over which is passed a
cord or chain, which, by being attached to a float in the water, or projecting arm
from gasholder,-is caused to rotate either one way or the other, this shaft is in
connection with a wheel, that has an insulated arm fixed to it, which in its
rotation throws over a rocking jockey piece, that is in electrical connection with
the Line wire, & connects it with either of the Battery poles, we will for instance say
that it has now been connected to the positive pole, the insulated arm still continuing
to turn in same direction picks up a tumbler that has fixed to it a pin working in an
eccentric groove or cam,-which is in electrical connection with the earth,-the
tumbler on attaining its topmost position then falls by gravity and during its fall
until it reaches the bottom position, connects the negative pole to earth, and thus
completing the circuit sends a positive current out to line to the Indicating Instru-
ment. Upon the shaft rotating in the opposite direction reverse effects take place,
and a negative current is sent out to line."
The Receiving or Indicating Instrument-This consists of a disc or drum in which
are one or more openings, behind which is placed one or more rotating dials or
drums with figures of inches, feet, & capacities marked on them or set with type for

page_text: printing purposes, the currents generated in sending instrument passing round the
coils of electro magnets attract, in either direction, a polarized armature, to which is
attached arms with pawls or the like, thus turning a star wheel which is geared into
the rotating dials bringing the figures marked on them before the openings by a step
by step motion-therefore making the Instruments direct reading or direct printing.

Improvements in Electrical Indicators for Shewing the Rise and
Fall of Gasholders and the Quantity of Gas therein, or Water
in Reservoirs and the Quantity therein, and for other similar
Purposes.
We, PEROIVAL WILLIAMS Electrician of 88, Shrubland Road Dalston in the
County of Middlesex and WALTER POWLES Electrician of 278, Roman Road Bow in
the County of Middlesex, 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 :-
The principal object of our Invention is to provide simple and efficient apparatus
for electrically indicating the height of Gasholders and the quantity of gas contained
therein, or the height of Water in Reservoirs and the number of gallons contained
therein. One part of the apparatus is the transmitting portion being that by which
an electric current is sent to an indicating or recording instrument at a distance along
a single line wire in one direction when the direction of the gasholder is in one direc-
tion such as ascending and the electric current being sent in the opposite direction
when the gasholder is descending.
The second part of the apparatus is the aforesaid indicating or recording instru-
ment at a distance from the transmitting portion the said second part being so con-
structed or arranged that its indication or recording is operated in both directions
by the electric currents transmitted by the first portion of the apparatus along the
one line wire in opposite directions in correspondence to the rise and fall of gasholders
or water in Reservoirs.
We will now describe our invention with reference to the accompanying drawings
as applied to indicating the rise and fall of gasholders from which its general appli-
tion will be readily understood. The apparatus consists of two principal parts-
videlicet-that shewn in figure 1 wherein the movements are given as to the level the
gasholder fluctuates to effect the transmission of the requisite currents of electricity
to and the actuation of the second part of the apparatus shewn in figures 3, and 5
which second part may be situated at any convenient distance from the first part of

page_text: the apparatus so that the height of the gasholder in any place at which the first part
of the apparatus is situated can be ascertained at a distance even of many miles from
the said place.
Referring to the apparatus shewn in Figure 1 and 2-A represents a wheel of a
diameter in accordance with the range of motion required over which is passed a cord
or chain attached to the top lift of a gasholder and over another pulley on top of
girder so as to make an endless Chain or Cord or for Water a Cord or Chain to one
end a Float and to the other end of the said Chain or Cord is attached a
counterweight. The shaft of the wheel A is mounted in suitable standards and has
fixed to it a toothed wheel A' which gears with a pinion B which runs on fixed shaft
to which an insulated Boss S with Pin B¹ is attached and at the end of said shaft the
tumbler B' hangs loosely so that it can be carried in one direction or in the other
direction and when brought to the top by Pin B¹ falls by its own weight. Pin F is
fixed in tumbler B' and by working in a cam controls and moves a long arm G to
the right or left; Arm G is attached to the Metal Case by spring G³. To the other
or lighter end of tumbler B* is fixed an insulated Pin B³ which on the tumbler being
rotated one way comes against the hinged arm of jockey Piece C and throws it over
to Contact Plate E and on continuing the movement on the next rotation 'the Pin B³
strikes against the hinged arm which is hinged so as to move only inwards and lifts it
up without moveing the Jockey Piece C off the Contact plate E. On the reverse
direction the Pin B strikes against the hinged arm and moves over the Jockey C to
Contact Plate D. One Pole of the battery is connected to D and the other Pole of the
battery is connected to E the Jockey C is connected to Line so if it rests on Contact
Plate D line is put to zinc and if it rests on Contact Plate E line is put to copper. All
the Plates are insulated from each other and from earth the Contact Arm G being
connected to earth and the tumbler B' in being lifted up the Pin F working in the
Cam brings over the Arm G onto the Contact Plate D' which is connected to Plate D and
being same Pole of battery as Line and on arriving at the top brings the arm to the
center and as it falls over by its own weight brings over the arm G on to plate E
which is connected the other Pole of the battery and completes the circuit by putting
that Pole to earth the contact is made all the time the top of Arm G is passing
over and back on Contact Plate E' and therefor making a long contact.
We will now describe the apparatus figures 34 and 5 which is an instrument that
is electrically operated from the distant station by that shewn in figures 1 and 2-
H is an electro magnet in front of which is a magnetized armature I pivotted to cock
piece I and is attracted to one or other poles of the electro magnet H according
to the direction of the current sent through the coils. At the back of the magnetised
armature I are two contact studs with adjusting screws J, and J, the magnetized
armature I being attracted to one pole of the electro magnet H makes contact with
stud J which sends the current on to electro magnet H' and attracts the armature K
which is fixed to a lever pivotted into standard R at R³, that carries at its other end a
hinged pawl which engages in one tooth of the star wheel L which has 12 teeth and
which is fixed to drum M, round which are 12 separate divisions for inches M' and
24 divisions for capacities, in cubic feet M³ and moves it one space representing one
inch, thus indicating the one inch movement and the two separate capacity figures,
the upper space M³ having figures in red and the lower in black so that the instru-
ment can be used for gasholders with double lifts the black figures first being read off
up to a certain height after which the red figures would come into use, these colored
figures alternating round the drum M-On moving drum M the twelfth time the
pin N enters star wheel N which is connected to pinion N in which works a toothed
wheel O and which turns pinion O' with toothed wheel fixed to drum P' turning
in standards R, R, (the said drum P' being divided into feet Ps and cubic feet P¹),
and moves it one space so that for every complete revolution of drum M the drum p
is moved one division and thereby indicates one complete foot movement. On the
magnetised armature I being attracted to the other pole of electro magnet H the
electro magnet H' is disconnected and electro magnet H³ is connected through stud J'
and attracts armature K³, which is fixed to a lever, pivotted into standard Rat R³,

page_text: that carries at its other end a hinged pawl, which engages in one tooth of the star
wheel L and moves it one division in the other direction and on the twelth movement
reverses the movement of 'drum P2 one division-As before described the Indicating
apparatus is connected up electrically as follows:-The current on line wire passes to
electro magnet H and divides part going through electro magnet H to earth and
part going through magnetized armature I by cock piece l' and stud J to electro
magnet H2 and then to earth, or if current is in opposite direction through to stud J'
to electro magnet H³ and then to earth.
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
First. The apparatus for transmitting along one line wire electrical currents in
opposite directions in accordance with the rise or fall of gasholders or direction of
motion of fluids substantially as hereinbefore described with reference to figures 1
and 2 of accompanying drawing.
Second. The long arm controlled by tumbler working in cam for making long
contact as shown in figures 1 and 2 of accompanying drawing for the purposes
