declare the nature of this invention to be as follows:-
The apparatus for which this application for a patent has been made, has for its
object to register the quantity of electricity consumed during a certain period of time,
and to serve, consequently as an industrial registering meter of electricity.
In the annexed drawing: Fig. 1 is a front elevation of the apparatus; Fig. 2 is a
side elevation. The Figs. 3 and 4 are respectively a top view and an elevation of a
modification.
The apparatus (Fig. 1 and 2) is composed of a clockwork communicating, by the
means of crank m, an oscillating movement between the points x and y. to the rod ?
a vertical galvanometer so constructed that the angular deviations are proportional to
the intensity of an electric current which traverses it. This galvanometer has on its
axis (d) a very fine ratchet wheel c. On this wheel the stop i is fixed at such a
point that when the galvanometer is at rest, i.e. not being traversed by any current,
that the rod in its oscillating motion only skims past it without giving any motion
to the wheel.
On the prolongation of the axle of the galvanometer and on the shaft k fixed by
the screw u on the frame of the galvanometer, moves with gentle friction a wheel c¹
with very fine ratchets. Between the two wheels c and c¹ and on the shaft k is a
lever the movement of which is independent of the wheel c¹. This lever has on
its extremities two catches or pawls r and 1 of which one engages in the wheel c
and the other r¹¹ in the wheel c¹. On the catch is fixed a small lever b in such a
manner that the rod in its movements from z to x liberates the catch allowing the
galvanometer to take an angular position corresponding to the intensity of the electric
current, and in its movements from a to z. again causes the catch r to catch before it
touches the stop i; is a stop on which the lever e¹ rests when at rest, and r¹ is an
arresting catch on the wheel c¹.
$
When the galvanometer is not traversed by any current, the stop i, being only
skimmed past by the rod the apparatus remains at rest. If now an electric current

page_text: traverses the galvanometer, its angular deviations being proportional to the intensity
of the current, the stop i takes a corresponding position and in its movements
from a to z the rod will bring back the stop i to its resting point p at the same time
the lever is lifted up by the catch in equal proportion and so is the wheel c¹ by
the catch
But in its return movement (from 2 to x) the rod I will take back the stop i as well
as the lever to their original positions, while the catch ¹ retains the wheel c! at the
point to which it was brought.
This wheel c¹ has thus registered the quantity of electricity which has traversed the
galvanometer during the period of time corresponding to one oscillating movement of
the rod 1.
If then for example, the oscillating movements of the rod are repeated every five
minutes, the quantity of electricity consumed is registered on the wheel every five
minutes, and by placing the wheel c¹ by any means of transmission in connection
with a finger moving over a graduated dial, the consumption of the electric current
may be read directly.
The figures 3 and 4 represent a modification of the apparatus, in which the ratchet
wheels are replaced by friction wheels. On the axle of a galvanometer d are fixed a
small plain wheel c¹ and a lever 1, the latter carrying at its extremity a stop i which
is fixed in such a position that when the galvanometer is on zero the rod l only skims
past it without giving any movement.
On the prolongation of the axle of the galvanometer, and on a fixed shaft K moves
with gentle friction the wheel c', having one of its sides, that which is turned towards
the galvanometer, covered with india rubber or any other substance offering a great
coefficient of friction. This wheel may be moved longitudinally on the shaft K, it is
pressed against the wheel of the galvanometer in the direction of the arrow ƒ by a
spring r. It is pushed in the other direction by the action of the lever l¹ which acts
periodically by friction upon the piece M movable round a hinge e" and carrying a
fork g which falls into the groove g on the nave of the wheel.
The rod in its periodical oscillations, acts in its extreme position y by friction on
the piece M, and forces it to move in the direction of the arrow f1 carrying the
wheel c in the same direction. In this movement the galvanometer is free (the
wheel c¹ no longer pressing against the wheel c¹¹) and the wheel of the galvanometer
and the stop are allowed to take an angular position corresponding to the intensity
of the current.
In its return movement, the rod leaves the piece M and the wheel c¹ presses
again, through the spring r, against the wheel of the galvanometer. These two wheels
are then in solidarity, and the rod acting on the stop i simultaneously carries back
the two wheels to an extent equal to the angular deviation of the galvanometer. The
rod continuing its oscillations will again displace the peice M, and again allow the
wheel of the galvanometer to move freely while the wheel c¹ will remain in the
position where it has been carried, and will then have registered the angular deviation
corresponding to that of the galvanometer during the time of oscillation of the rod 7.
In placing this wheel c in gear with any transmission mechanism with a finger
moving over a graduated dial the consumption of electricity may be read directly.

1, HENRY TUDOR of Rosport, Grand Duchy of Luxembourg, Inventor 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 apparatus for which this application for a patent has been made, has for its
object to register the quantity of electricity consumed during a certain period of time,
and to serve consequently, as an industrial registering meter of electricity.
In the drawing filed with the provisional specification, Figure 1, is a front elevation
of the apparatus, Figure 2 is a side elevation; the Figures 3 and 4 are respectively a
top view and an elevation of a modification.
The apparatus (Figures 1 and 2) is composed of a clockwork communicating by
means of crank m, an oscillating movement between the points x and y to the rod 1;
a vertical galvanometer so constructed that the angular deviations are proportioned to
the intensity of an electric current which traverses it. This galvanometer has on its
axis d, a very fine ratchet wheel C. On this wheel, the stop i is fixed, at such a point
that when the galvanometer is at rest, that is, not being traversed by any current, the
rod in its oscillating motion only skims past it without giving any motion to the wheel.
On the prolongation of the axle of the galvanometer and on the shaft & fixed by the
screw on the frame of the galvanometer, moves with gentle friction, a wheel c¹ with
very fine ratchets. Between two wheels c and c¹ and on the shaft k is a lever l¹, the
movement of which is independent of the wheel c¹. This lever has on its extremities
two catches or pawls r and of which one r engages in the wheel C and the other ril
in the wheel c¹. On the catch r is fixed a small lever b, in such a manner that the
rod in its movements from to a liberates the catch allowing the galvanometer to
take an angular position corresponding to the intensity of the electric current, and in
its movements from a to z again causes the catch to catch before it touches the
stop; is a stop on which the lever rests when at rest, and ¹ is an arresting
catch on the wheel c².
When the galvanometer is not traversed by any current, the stop i, being only
skimmed past by the rod 1, the apparatus remains at rest. If now an electric current
traverses the galvanometer, its angular deviations being proportioned to the intensity
of the current, the stop i takes a corresponding position and in its movements
from a to 2,
the rod will bring back the stop i to its resting point p at the same time
the lever is lifted up by the catch in equal proportion and so is the wheel (by
the catch r¹¹.
But in its return movement (from z to 2) the rod will take back the stop i as well
as the lever to their original positions, while the catch ¹ retains the wheel C' at the
point to which it was brought.
This wheel C¹ has thus registered the quantity of electricity which has traversed
the galvanometer during the period of time corresponding to one oscillating movement
of the rod l.
If then, for example, the oscillating movements of the rod are repeated every
five minutes, the quantity of electricity consumed is registered on the wheel every five
minutes, and by placing the wheel C₁ by any means of transmission in connection
with a finger moving over a graduated dial, the consumption of the electric current
may be read directly.
The figures 3 and 4 represent a modification of the apparatus, in which the ratchet
wheels are replaced by friction wheels. On the axle of a galvanometer d are fixed a
small plain wheel C₁ and a lever 1, the latter carrying at its extremity a stop i which

page_text: is fixed in such a position that when the galvanometer is on zero the rod ♬ only skims
past it without giving any movement.
On the prolongation of the axle of the galvanometer, and on a fixed shaft K moves
with gentle friction the wheel C¹, having one of its sides, that which is turned towards
the galvanometer, covered with india rubber or any other substance offering a great
co-efficient of friction. This wheel may be moved longitudinally on the shaft K, it is
pressed against the wheel of the galvanometer in the direction of the arrow f by a
spring r. It is pushed in the other direction by the action of the lever l which acts
periodically by friction upon the piece M movable round a hinge C and carrying a
fork which falls with the groove g on the nave of the wheel.
The rod in its periodical oscillations, acts in its extreme position y by friction on
the piece M, and forces it to move in the direction of the arrow f1 carrying the
wheel C in the same direction. In this movement the galvanometer is free (the
wheel C no longer pressing against the wheel C) and the wheel of the galvanometer
and the stop i are allowed to take an angular position corresponding to the intensity
of the current.
In its return movement, the rod leaves the piece M and the wheel C¹ presses
again, through the spring r against the wheel of the galvanometer. These two wheels
are then in solidarity, and the rod 1 acting on the stop simultaneously carries back
the two wheels to an extent equal to the angular deviation of the galvanometer. The
rod continuing its oscillations will again displace the piece M, and again allow
the wheel of the galvanometer to move freely while the wheel will remain in the
position where it has been carried, and will then have registered the angular deviation
corresponding to that of the galvanometer during the time of oscillation of the rod 1.
In placing this wheel in gear with any transmission mechanism with a finger
moving over a graduated dial, the consumption of electricity may he read directly.
Having now particularly described and ascertained the nature of my said Invention,
and in what manner the same is to be performed, I declare that what I claim is
1. In an electrical meter the combination of two independent wheels of which one
being fixed to the galvanometer makes consequently the same angular deviations as
the galvanometer itself whilst the other is periodically either forming a whole with the
first or independent thereof this being effected either through the medium of a lover
provided with two pawls stopping these wheels or through friction.
2. An electrical meter consisting of a galvanometer giving a deviation proportional
to the current passing through it, said galvanometer actuating a double pawl lever, in
combination with a clock work which through the medium of a connecting rod,
actuates a wheel in such a manner that any deviation imparted to the galvanometer
lever by the passage of an electric current, is reproduced in equal quantity by the
wheel in a determinate time.
3. In an electrical meter, the combination of two independent wheels of which one
is actuated by the pawl of a proportional deviation galvanometer whilst the second
forming a whole with the first in one direction is set in motion through the medium
of a stop and connecting rod actuated by a clock work movement.
4. In an apparatus registering periodically the deviation of a vertical proportional
deviation galvanometer the combination of the oscillating motion of the connecting
rod (1) actuating a lever (2) through the medium of the stop (i) and pawl (r) and
wheel (c) actuated by lever (12) and pawl (2) for the purpose of serving as an
electrical meter.
The whole constructed and operating substantially in the manner described and
illustrated in the accompanying drawings.
Dated this 29th day of February 1888.
