CLARENCE A. BCDDIE, or PITTSBURGH, PENNSYLVANIA, AssIqNoRTo wEsTINGHoUsE ELECTRIC AND MANUFACTURING COMPANY, A CORPORATION 0E PENNSYLVANIA.
AmrERE-IIOUR METER.
To all whom it may concern.'
Be it known that I, CLARENCE A. Bonnin, a citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny `and State of Pennsylvania, have invented a new and useful Improvement in Ampere- Hour Meters, of which the following is a specification.
My invention relates to electrical-measuring instruments and particularly to amperehour meters.
The object of my invention is to provide a meter of the above indicated character that shall have means for so controlling the operation of its movable members that they will rotate substantially in accordance with the rst'power of the current traversing its windings.
My copending U. S. application .Serial No. 88,974, filed on even date herewith, discloses an ampere-hour meter having an escapement device for so retarding the movement of its movable member that its speed will vary substantially in accordance with the lirst power of the current traversing its windings. In my present invention, I provide two movable members to which an actuating force is applied that is proportional to the square of the current traversing the windings of the instrument, and I intercon nect the two movable members in such manner that one so controls the operation of the other that their speeds vary substantially in accordance with the first power of the current traversing the windings.
Figure 1 of the accompanying drawlng is a top view, partially in plan and partially in section, of an ampere-hour meter embodying my invention; Fig. 2 is a side view, partially in elevation and partially in section, of the meter shown in Fig. 1, and lFig. 3 is a front view, partially in elevation and partially in Section, of the meter shown in Figs. 1 and 2.
An ampere-hour meter 1 comprises a magnetizable core member 2, a main winding 3, auxiliary windings 4 and 5 and two armatures 6 and 7. The windings 3, 4 and 5 are so disposed on portions of the magnetizable core member 2 and so connected that the Specification of Letters Patent.
, eccentric 13 and a pin 14 are also mounted.
Patented Ma'y13, 1919.
Application tiled April 4,1916. Serial No. 88,973.
armatures 6 and 7, which are disposed in the air gap of the core member 2, will ordinarily have torques that are proportional to the lsquare of the current traversing the main winding 3.
` The armature 6 is mounted on a shaft 8 upon .which an eccentric 9, a pin 10 and a pointer 11 are also mounted.l The armature 7 is mounted on a shaft 12 upon which an A supporting bracket 15 is attached to the Amagnetizable core member 2 and is adapted to support a pin 16 that serves as a. pivot for two lever arms 17 and 18. The arm 17 is provided with an eccentric strap 19 at one end that is adapted to engage the eccentric i) and with a stop 0r projection 20 at its other end that is adapted to engage the pin 14. Similarly, the arm 18 is provided with an eccentric strap 21 at one end that is adapted to surround the eccentric 13 and with a projection or stop 22 at its other end that is adapted to engage the pin 10.
If the lever arms 17 and 18 were not provided, the armatures 6 and 7, and, consequently, the pointer 11, would rotate inaccordance with the' square of the current traversing the winding 3. However, when the arms 17 and 18 are provided, one armature so controls the movement of the other that the pointer 11 will rotate in accordance with the first power of the current that traverses the winding 3, and will, thus, const-itute an ampere-hour meter.
When the armature 7 rotates, the eccentric 13 will cause the arm 18 to move to such position that the stop 22 will disengage the pin 10, This will permit the armature 6 to rotate. However,.when the armature 6 rotates, the eccentric 9 will cause the lever arm 17 to be so moved that thestop 20 will be disengaged from the pin 14 which has been moved into engagement with it by the previous movement of the armature 7. This will permit thearmature 7 to again move, 95
and consequently, these actions will continue 4 so long as the windings, 8, 4 and 5 are energlzed. i l
It will be understood that any suitable indicating or integrating mechanism may be 100 i connected to .either of the shafts, and :va-
rious other modifications may be made in my invention without departing from the spirit and scope-of the saine as set forth in the appended claims.
I claim as my invention:
1. An ampere-hour meter comprising two rotatable members, means for simultaneously applying similar actuating forces thereto, and means for causing the rotatable members to control the movement of each other.
2. In an ampere-hour meter, the Vcombination with two movable members and electromagnetic means for applying an actuating force tothe said members that varies subs stantially in accordance with the .square of the current traversing its windings, of means operatively connected between the movable members for causing them to move in accordance with the current traversing the windings.
3. In an ampere-hour meter for an electric circuit, the combination with two mov able members and means for simultaneously applying an actuating force to the said members that is proportional to the square of the current traversing the circuit, of means for causing the movable members to so retard the movement of .eachother that they move in accordance with thecurrent traversing the circuit.
4. In an ampere-hour meter for an electric circuit, the combination with two movs able members and means for applying an actuating force to the said members that is proportional to the square of the current traversing the circuit, of means pivoted between the two movable members for causing the movable members to so retard the movement of each other that they move in accordance with the current traversing the circuit.
5. In an ampere-hour meter for an electric circuit, the combination with two mov able members, and a single means for applying an actuating force to the said movable members that is proportional to the square of the current traversing the circuit, of an eccentric and a pin mounted on each of the movable members, and two pivoted members severally having an eccentric strap at one end for cooperation with one of the said eccentrics and a stop at the other end for so cooperating with one of the said pins that the movable members are adapted to move in accordance with the current traversing the circuit.
6. In an ampere-hour meter for an electric circuit, the combination with two Inovable members, and a single means for applying an actuating force to the 'said movable members that is proportional to the square of the current traversing the circuit, of means actuated by each of the movable members to cause one to control the movement of the other.`
In testimony whereof I have hereunto subscribed my name this 27 th day of March,
CLARENCE A. BODDIE.
