. My invention pertains in general to integrating systems and specifically relates to an integrating system for use in recording consumed electrical energyjsuch as in commercial power distribution.

In commercial power distribution, the consumers power consumption during certain periods of time is high, while, at other times, the consumers'power, consumption is relatively low. That is, the power demand curve for central station generating apparatus shows decided peaks at certain hours of the day. For example, at that period of the day during which darkness begins to occur, it

will be found that the power demand curve rises sharply and decreases towards the later hours of the evening. Such conditions make it necessary to'provide suflicient generating apparatus to supply the .limited periods of maximum demand. Such generating apparatus will not be operating at maximum efficiency during the other periods in which the power demand is considerably less. It will be obvious that it is verydesirable to direct efforts towards equalizing the power consumption loads whereby the power generatingapparatus can be operated at more nearly the samelevel during the entire day. It is, therefore, to the advantage ofthe power 1 distribution company to offer certain inducements to the consumer for using power dur ing those periods of the day when the demand is enerally low.

- ne of the objects of my inventionconsists in providing a system for recording a consumerspower consumption at different rates at difierent times. 7

Another object consists in providing a duplex system for the integration of a'consumers power consumption having auto matically controlled means for rendering different recording agencies effective for different periods of the day.

A still further object consists in providing a clock controlled meter service. for sepa-.

rately recording a consumers power consumption for different predetermined time intervals. V

I accomplish these and other desirable objects in a novel integrating system employ- 1932. Serial no. 603,309.

ing a watt-hour meter having a dual set-of recording dials rendered individually opera-. tive at different times of the day under control of a clock for recordingthe consumers power consumption.

Fig. 1 is apreferred embodiment of my invention,and" f 3 Fig. 2 is amodification thereof.- 1 Referring .tofthe drawings in detail and particularly to Fig. 1, power lines lextend from generating equipment 3 in central'station 2. Power line's land generating equipment 3 are indicative of means for producing and distributing commercial alternating current of regulatedfrequency under control of a masterclock 4. T v f At a point remote fromthe'jcentral station 2, such as in .a consumers dwelling, there is provided an electric clock 6 operated by a self-starting synchronous motor '7' connected (0 with the power lines 1 and adapted; to keep, in step with the alternations of the regulated current delivered from the generating equipment 3. Clock 6 is provided with contacts 8 and 9 adapted for engagement by the hour hand 10 of the .c1ock 6. The hour hand 10 is connected with power-lines 1 and contacts 8 and 9 are respectively connected with magnets 11 and 12. of the alternating current type. It will, of course, beunderstood that other arrangements under control of the clock 6 canbe employed forselectively] estab- I lishing'connections' with themagnets 11 and 12 at predetermined times. For example," a contact sector could be rotated under control of the clock mechanism for engagement with contact brushes connected with the magnets.

' Armature .14 ispivotedbetween magnets 11 and 12 for actuating a clutch shifting arrangement later described.- '.Oneend of the armature 14' carries avcontact 15 which en gages with either of two 'follower contact springs 16 and 17 connected with the magnets 11 and 12, respectively, as shown. The contact 15 is connected with the power lines 1. The consumers load. 18,- representative of any power consuming devices such as electric lamps, heaters and the like, is connected through the fieldcoils -19, ofia specialtypeof I watt-hour'meter, to the powerlines 1. The

field coils 19 produce the rotation of disc 20 in accordance with the magnitude of the power consumed by load 18 in the well known manner. The disc 20 is mounted upon a shaft journaled in a frame 21 and is secured to a worm 22 in engagement with a worm gear 23. The worm gear 23 is splined to a shaft 24 which is rotatably and slidably mounted in members integral with the frame 21. The worm gear 23'is prevented from lateralmotion by abutting members on either side thereof integral with the frame 21. The shaft. 24

carries, at either end, the driving members of clutches 25 and 26, respectively. I Thedriven members of clutches 25 and 26 are connected with dial recording units 27 and 28, respectively. The units 27 and 28 each comprise gears for rotating hands associated with sets of .dials, such units being well known in connection with watt-hour meters. The units 27 and 28 are individually utilized to record the consumers consumption of elec ing' unit 28 from disc 20, while, when the armature 14'is attracted by magnet 12, the members of clutch 25 will be brought into engagement with eachother for imparting rotary motion to the recording unit 27 from disc20. w

In the operation of my systemfor the recording ofa consumerspower consumption,

the apparatus associated with the watt-hour recording system mayv be in the position indicated in Fig. 1 whereby power deliveredto the consumersload 18 will cause disc 20 to revolve and impart rotary motion to the recording unit 28. for recording the consumers power consumption at a predetermined rate as indicated by the dials on the unit 28. During the time that the consumers load 18 is receivingpower from the regulated generating equipment 3, the clock-6 is being driven by motor 7 in synchronism with master clock 4.

The energization of magnet 12 by the engagement of clockhand 10 with contact 9 will cause the armature 14 to be attracted thereto into engagement with follower contact 16 and out of engagement with follower contact 17 thereby interrupting the circuit to magnet 12. The movement of armature 14 under control of magnet 12will cause the release of clutch 26 and engagement of clutch 25, whereby the indicating. device 28 will cease to operate and-theindicating device 27 will function to record the consumers power consumption under control of disc 20.

When the hour hand 10 has moved into engagement with contact I 8, a circuit will be established from power lines 1 through follower contact 16,to magnet '11. The energization of magnet .11 will attract armature 14, the movement of which will interrupt the circuit to magnet 11when contact 15 leaves the follower spring 16. The movement ofarma ture 14 will cause the disengagement of the membersof clutch 25 and the engagement of the members of clutch 26 to resume the positions shown in'Fig. 1, whereupon the indicating unit 27 willcease to function and indicating unit 28 will serve to record the consumers power consumption as determined by the rotation of disc 20.

At periodic intervals the meter reader may note the readings of the dials of recording unit 27 and the dials of recording'unit 28, thereby obtaining the record of the total consumption of the consumers load as recorded at different rates, depending upon the time of the day during which the consumer used power from lines 1. It will be understood, of course, that the contacts 8 and 9 may be arranged for controlling the operation of magnets 11 and 12 at any desired time and that the recording rates of units 27 and 28 can be adjusted in any desired manner.

Fig. 2 represents another form of my invention foraccomplishing duplex integration of a consumers power consumption. In Fig. 2 the magnet 11 is connected in the output circuit of an amplifier 33, while magnet 12 is connected in the output circuit of an amplifier 34. The amplifiers 33 and 34 are respectivelyconnected through filters 35 and 36 to power lines. 1. The filters 35 and 36 are each responsive to a particular carrier frequency impressed'on power lines 1.

The power lines 1, as in Fig.1, are connected to the generating equipment'3 for producing regulated alternating current und'er control of the master clock 4. In the arrangement of Fig. 2, the contacts 8 and 9 of clock 6 are connected with relays in wired radio transmitters 38 and 39. The output circuit of transmitter 38 is connected through a filter 40 to power lines 1 and the transmitter 39 has the output circuit thereof connected through a filter 41 to power lines 1.

When the hour hand 10 engages with contact 8 the transmitter 38'is momentarily energized for transmitting a carrier frequency impulse over power lines 1 at a frequency to which filter 35 is responsive. This carrier frequency impulse will be amplified by amplifier 33 and cause the momentary energization of magnet 11 for attracting an armature 43 which corresponds to the armature 14 of Fig. 1. When the hand 10 has moved into engagement with contact 9 the transmitter 39 will be momentarilyenergized for-sending a carrier frequency impulse over power lines 1 at a frequency to which filter 36 is responsive. This carrier frequency impulse will be amplified by amplifier 34 for causing the momentary energization of magnet 12. The energization of magnet 12 will attract armature 43 in the opposite direction, rendering unit 27 effective for recording the consumers power consumption. Switches 44 and 45 are provided for manually controlling the operation of transmitter 38 and 39, respectively. These switches 44 and 45 enable an operator at the central station 2 to control the operation of the consumers integrating device in emergencies of unexpected power demand when it is desired to dispense with the automatic control features of my system.

It will be evident now, that the clock 6 in Fig. 2, in contradistinction to the arrangement of Fig. 1, is situated at the central station 2 for remotely controlling the operation of the consumers watt-hour integrating device. It will be understood that, in accordance with my invention, a great many difierent integrating systems can be connected with the central station 2, the representation of but a single integrating system connected therewith being shown only for sake of simplicity of description. 7 Although I have shown a preferred embodiment of my integrating system it will of course be understood that various modifications may be made therein without departing from the intended scope of my invention. 1 do not therefore desire to limit myself to the foregoing except insofar as may be pointed out in the appended claims.

What I claim as new and original and desire to secure by Letters Patent of the United States is: v

1. A system for measuring the consumption of power by a consumers load comprising, a consumers load, a central station including means for producing regulated alternating current, wire lines extending from said central station to said consumers load for supplying said alternating current thereto, a device for producing mechanical motion in accordance with the consumption of said alternating current by said consumers load, 7
