Title: Improvements in or relating to Electricity Meters.
Inventor: BOULT ALFRED JULIUS
Filed: 1899-12-09
Granted: 1900-08-04
Abstract: 24,514. Boult, A. J., [Salda±a, F.]. Dec. 9. Energy and quantity meters. - An oscillatory motor meter has stationary main current field coils 4, Fig. 1, and a shaft carrying iron projections 3, 3<1> on a core 2, which is magnetized in opposite directions alternately by two coils 1, wound together and connected between the supply mains through a two-way switch 7, shown in plan in Fig. 3. The core 2 may be laminated, for use with alternating currents, or replaced by coils. The oscillation of the shaft 2, thus produced, is retarded by one or more plates 20, carried by it, moving between radial partitions in a cylindrical box 19, containing air. The switch 7 is operated by a pin engaging a forked lever 29, which is oscillated by a crank 12 on the motor shaft ; the movements of the lever 29 and switch are assisted by the action of magnets 10 on the projection 3<1> and the nearer end of an armature 9 on the lever 29. The two coils 1 are connected oppositely to the switch contacts, which are placed so that in the middle position of the switch current passes through both coils in parallel, but oppositely, so that no magnetic effect is then produced, sparking being thus prevented when the switch leaves either contact. The magnets 10 may be permanent, or electromagnets or solenoids in series with the coils 1. The armature 9 may be polarized. The lever 29 drives a counter by a pawl and ratchet. The motor shaft may be acted on by a spiral spring. The meter may be used to measure electric quantity if the core 2 is magnetically "saturated," or energy otherwise. The core may have one projection 3 only, this being acted on both by the field coils 4 and by the magnets 10. The field coils may be shunted by an automatic switch, or by an electromagnetic switch controlled from a central station, to change the rate of the meter when desired. For a three-wire system the field coils 4 are doubly wound, and for a five-wire system four coils are provided to act on the projections 3, 3<1>. The switch 7 may be operated electrically only, by providing the armature 9 with two coils, oppositely connected in parallel through two silver spring contacts, which are opened alternately by a crank on the motor shaft.
