FOR MEASURING ELECTRIC FORCE AND CURRENTS."
The apparatus consists of a solenoid and sucking magnet with a counter-
balancing spring, or an electro-motor or motors with armatures capable of being
moved, working by any well known mechanical device a pencil or style brought
into contact with paper or other equivalent and so marking the movements of the
sucking magnet, or electro motor and its attachments put into motion by the
electric current passed through the coils of the solenoid or the electro-motor. The
paper or material to be so marked is made in a continuous roll or rolls and is
actuated by clock mechanism and thus the duration as well as the force and
quantity of the current registered..
The clock mechanism being so arranged that immediately the clock runs down
the current is automatically cut off. It is contemplated to place the apparatus on
the premises where the electricity is used and thus let it serve as a meter for
guaging the use or in lieu of the clock mechanism.-The movement of the paper
may be effected by an electro motor.

the said Joseph Samuel Beeman, William Taylor, and Frank King in the-Great
Seal Patent Office on the 21st March 1883.
JOSEPH SAMUEL BEEMAN, WILLIAM
TAYLOR, and FRANK KING, all of
110 Cannon Street, in the County of Middlesex, NEW OR IMPROVED APPARATUS
FOR MEASURING ELECTRIC FORCE AND CURRENTS,"
The apparatus relates to a solenoid and sucking magnet with a counterbalancing
spring, or an electro-motor or motors with armatures capable of being moved,
operating by means of any suitable mechanical device a pencil or style brought into
contact with paper or other equivalent and so marking the movements of the
sucking magnet, or electro-motor and its attachments, put into motion by the
electric current passed through the coils of the solenoid or the electro-motor. The
paper or material to be so marked is made in a continuous roll or rolls, and is
actuated by clock mechanism, or in lieu of the clock mechanism the movement of
the paper may be effected by an electro-motor, and thus the duration as well as the
force and quantity of the current registered. The clock mechanism is so arranged
that when it is desired to turn on a current to light any lamp, motion is first given
to a clock, which, by its impactive movement, then closes the circuit so as to send
a current along a main wire, immediately the clock runs down the current is.
automatically cut off. It is contemplated to place the apparatus on the premises
where the electricity is used and thus let it serve as a meter for gauging the use.
The drawings serve to illustrate the manner of performing the invention. In the
drawings, like figures represent like parts. A, Fig. 1, represents a solenoid; B is a
suɩking magnet carrying coils of fine wire C, D is a spiral spring for regulating the
distance into the solenoid A which the sucking magnet B is drawn by variations
in the intensity of the current; E is a multiplying arc, to which is attached the
cords F F. The cord F being attached to the sucking magnet B, and cord F' being
attached to a pencil carrier G; the latter having a motion between a pair of
rails H, or equivalent, and marking a curved or other line upon the paper. I is a
roll of paper, said paper roll being unwound and drawn along under the pencils or
styles by the studded roller J, which latter may be actuated either by direct
attachment to a clock, or by means of the electro-motor, Fig. 2; k is a pencil or
style and holder, to mark zero line on the paper as it is drawn along by the studded
roller J. Fig. 4 shows another arrangement, by which the arc E may be dispensed
with, and in its place the slotted bar El may be actuated from the sleeve L; but
evidently any parallel motion may be used without departing from the nature of
the invention.
The electro-motor Fig. 2 is actuated by the contact breaker Fig. 3, which, made
to form part of any clock mechanism, is so arranged that at every revolution of
the wheel M a contact is made through the hanging rod N and the mercury cup o
round the electro-magnet P, Fig. 2. When the electro-magnet P is excited as
described, it will attract the armature Q, which actuates the click or pawl R,
thereby giving motion to the ratchet wheel S, the latter being attached to the
studded roller J. Fig. 5 represents a method of setting the clock in motion
directly any current is required, the detent T being actuated by the magnet U
gives an impulse to the toothed balance wheel V, the detent T being kept clear of
the toothed wheel by the attraction of the electro-magnet U on its armature. W is
an ordinary switch. Fig. 6 shows a governor actuated by the motion of the
clock; when said governor rotates, it acts upon the lever a at a¹, causing said lever,

page_text: with its attached contact piece f, to enter the mercury cup 6 and so complete the
main circuit. x and y are the points where connection is made with the source of
supply employed for supplying electricity to the place where our improved
apparatus is used, and which we term generator points. The action of the
apparatus is as follows:-Upon completion of the circuit by means of the switch W,
the current passes along the shunt wire c, round the sucking magnet coils C, Fig. 1,
and thence round the electro-magnet U, Fig. 5, and thereby setting the clock in
motion of which V is the balance wheel, said clock actuating, as before described,.
the roller J, said roller moving the paper, the clock at the same time actuating the
governor, Fig. 6, and completing or making contact through the main circuit
through the lamp or translating device d. The circuit being complete, the current
now passes along the main conductor e, through the lever a, mercury cup b,
extension of main conductor el, through lamp or translating device d. and
continuation of main conductor e², through switch W and along e³, through solenoid
coils A, Fig. 1, to the generator. It will be seen that upon the completion of the
main circuit, as before described, the solenoid will draw the sucking magnet into
its core, at same time actuating the multiplying are E, Fig. 1, or its equivalent,
thus giving motion to the pencil carrier G along the rails H by means of the cord F',
thereby recording on the paper the amount of current that is passing in the
circuit at same time the clock is giving motion to the paper. It will be seen that
on the motion of the pencil according to the variation in the strength of the current,
combined with the movement of the paper in a direction perpendicular to the
movement of the pencil, a diagram will be produced showing the amount of
current that has hean pessing during any given time.
CLAIMS.
1. The combination of parts forming the apparatus for measuring electric force
and currents, substantially as described and illustrated.
2. The combination consisting of mechanism for starting a clock, a clock and
contact making and breaking apparatus used for breaking and closing the main
circuit, substantially as described and illustrated.
3. The combination of a shunt wire connected with one of the main conductors
and a generator point, whereby any switch in the main circuit being actuated will
start the clock and close the main circuit, substantially as described and
illustrated.
In witness whereof we the said Joseph Samuel Beeman, William Taylor, and
Frank King, have hereunto set our hands and seals this 21st day of March
