COAL and ASHES CONVEYORS

of the correct type are the most efficient and economical means of handling and storing at the Power Plant.

THE PECK Overlapping Pivoted Bucket CARRIER

is the most popular of the Pivoted Bucket Conveyors. Successful installations are numbered in the hundreds-the total length in use would exceed 20 miles in length. Handles coal and ashes at lower cost per ton than any other type of conveyor.

Peck Carrier Book No. 120 not only shows the construction and actual photographic installations, but gives the reasons for its superiority over all other types.

Important Announcement

Weston

Model 310

Single-Phase and Direct Current Portable Electrodynamometer

WATTMETER

For use on either A. C. or D. C. Circuits with a guaranteed accuracy of 4 of 1 per cent., full scale value, on circuits of any frequency to 133 cycles per second or any wave form.

Double ranges are provided for both current and voltage circuits. All current ranges can be used for 100 per cent, overload capacity indefinitely without introducing error.

Their movable systems have an extremely low moment of inertia; effectively damped; indications are independent of room temperature and the instruments are shielded from external magnetic fields.

The scales, which are 5 inches long, are uniform throughout their entire length, a characteristic of great importance. Each scale is hand calibrated and provided with a mirror over which the knife-edge travels, and pointers are equipped with a simple zero setting device. For complete information regarding Model 310 Wattmeters (illustrated) and Model 329 Polyphase Wattmeters, write for Bulletin 2002. Other models in this group are 341 A. C. and D. C. Portable Voltmeter described in Bulletin 2004, and Model 370 A. C. and D. C. Portable Ammeter, described in Bulletin No. 2003.
