Definitions

• the object I have in view is to produce si mple and efficient apparatus for measuring or determining the electrical energy consumed in a circuitwherein translating devices are ar ranged in, multiple arc, and especially to produce a meter suitable for use in my multipleare system of electrical distribution.
• This I accomplish by arranging in the main line of I whose needle controls circuits to electricallyoperated apparatnsjwinchapparatus 'eonirdis an indicating or registering device.
• thea-pparatus controlled by the galvanometer is used to adjust the lateral position of a stylus bearingupon atravelingstrip of paper, and marking thereon anirregular line, which will indicate at all ti mes the flow of the current.
• the apparatus controlled by the' galvanometer may be of any suitable character; but I prefer to use an ap paratus similar to that described in my application No. 99,559, the motion being produced by the effect of the current upon a galvanometer needle or bar, which carries an arm closing circuit at moving contacts to oprating magnets moving another arm carry- :ng the stylus and following the movements of the galvanometerarm. Thenecdle of the galvanometer is arranged in a magnetic field, and is moved out'of that field more or less by variations in the current.
• the strip may be moved by any suitable device, aclockcircuit.
• l 2 are the street conductors or mains
• 3 4 are the conductors of a house-circuit having lamps
• B is a galvanomctcr located in the main line of the circuit '3 4; or, as will be well understood, it may be arranged in a shunt around a definite resistance in said circuit.
• the galvanomcter shown has its needle a located in the field of a. magnet, b.
• the electrical conductor of the galvanometcr is a straight strip, 0, of low resistancc,located directly in thecircuit 3 4; but one or more coils could be used if the galvanometer were arranged in a shunt around resistancifmie needle a is pivoted directly upon the conducting-strip c, and carouter end between contacts cf, carried by an arm, (J, which follows closely the movements of the galvanometcr-arm.
• This arm 0 is secured to a shaft, 7, which is preferably inline with the pivot of the needle a, but, for convenience of illustration, is shown as located back ofthe pivot of a.
• the electromagnets F G are in divisions of a multiple-arc circuit, 5 6, from 3 4. This circuit commences at 5 on the strip 0, forming part of conductor 3,and terminates at 6 on theconductor l. The circuit divides at the point 7, and extends to the contacts 0 f, the clcctroanagnets being lo cated in the divisions of the circuit.
• the resistance R is prefcrabl y included in the circuit.
• the circuit 5 (i is completed by the touching of either contact a or f by the arms d, andone division or the other of this circuit is completed, according to whether the arm touches one or the other contact.
• the closing of either branch of circuit 5 6 causes the electromagnet to move the arm 0 so that the coutaetwill move away from the needlc-arm and break the The needlc'arm will follow up the contact until the entire deflection due to the variation in the currentis accomplished.
• This arm plays freely at its arm 0 at any suitable point carries a stylus, in.
• What I claim is 1.
• the combination with a galvahometer arranged to be affected by the current of the circuit in which the consumption of electrical energy is desired to be measured, of moving contactsat which circuits are made and broken by the galvanometerarm, and a registering or indicating apparatus controlled. thereby, substantially as set forth. 3.
• the combination In an electrical. meter, the combination,
• the combination with a galvanometer-arm, of another pivoted arm carrying on its freeend insulated contacts, between which the galranometer-arm plays, two electro-nia-gnets located in circuit with such contacts and operating pawl-levers, oppositely-arranged ratchet-wheels worked by such pawl-levers and moving said pivoted arm, and a registering or indicating apparatus, substantially as set forth.
