Abstract: 532,297. Supply meters. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Aug. 25, 1939, No. 24475. Convention date, Aug. 25, 1938. [Class 37] The light load and phase balance adjusting devices of an induction meter are mounted on a common support and are attachable to the meter as a complete unit. The meter core 1, Fig. 1, has a pctential pole 2 and current poles 3 all located above a magnetic flux return member 4. For phase balance adjustment a magnetic member 5 is mounted to slide in a dovetailed recess 6 in the member 4. Light load adjustment is effected by means of a brass or other conducting segment 7 which may be rotated across the face of the potential pole 2. The driving disc D is positioned between the segment 7 and the poles 2, 3. The plate 5 and segment 7 are mounted on a single support 8 having slotted arms 9, Fig. 3, and flanges 10, 11. The support 8 is fixed to the core 1 by inserting the arms 9 through openings 12 until the slotted portions project on the opposite side of the core. The slotted ends are then deformed or solder is applied thereto. The magnetic plate 5 is adjusted by means of a screw 13 passing through holes 15 in the flanges 10, 11 and a tapped hole 19 in a lug 18 on the plate 5. The segment 7 is fixed on the reduced end 20 of a shaft 21 rotatably mounted in a boss 22 on the support 8. The shaft 21 has an enlarged head 24 formed with a slot 26 into which is fixed a .lever 25 slotted to form fingers 30 which are oppositely bent as shown. An adjusting screw 14 mounted in holes 15 engages a tapped hole in a sliding block 31 carrying pins 33, 34 which engage opposite surfaces of the fingers 30. The pin 33 may be extended so as to pass into a guide slot 35 in the support 8. The pressure in opposite directions of the spring fingers 30 on the pins 33, 34 tends to lock the block 31 in any position, and prevents backlash. Alternatively the lever 25 may be formed by bending a strip of brass as shown in Fig. 5 so as to form eyes 38 at the ends of the fingers 30. In another construction, Fig. 6, a flexible strip 39 of copper or brass is fixed to the head 24 and is punched to form a disc 40 connected to the body of the strip by a narrow tongue 41. The fingers 43 may be eliminated by locating the tongue 41 diametrically opposite the position shown. In an alternative construction, the screw 14 engages a worm-wheel or a brass strip on the head 24 formed with one or more teeth to engage the threads of the screw. Specification 466,544 is referred to.
