in the controller, the current is caused to enter the pilot motor from the positive side of the circuit through leads Nos. 1 and 2, passing out through lead No.3 to the negative side of the circuit, the movable field will advance one-twelfth of a revolution. It • will thus be seen that different current combinations through, the pilot motor will cause the field of the pilot motor to rotate ... The successive current combinations, polarity of armature poles_ and positions of revolving fields are shown in the table, Fig. 29. Fig. 29 also shows the method of testing each individual" armature spool, the series connection of two spools on each annature pole for the proper polarity of armature pole and the, method of interconnecting the six pairs of armature spools. . Operation.-Referring to Figs. 22,23, 24 and 39, the opera", tion of the elevating mechanism will be described. Rotating the elevating handwheel of the controller through two-thirdS of a revolution causes the revolving field, part 248 (Fig. 39)'1 of the pilot motor, part 63, to advance one-third of a revolution't The rotation of this pilot motor field causes the cam cylinder'4 part 240 (Fig. 39), to rotate through 20 degrees by means of th~ spur gears, parts 225, 221, 222 and 224, and the bevel box gearing, part 226 (Fig. 23), and the bevel gears shown mounted im,id~ the cam. cylinder, part 240 (Fig. 39). The movement of thi cam cylinder, part 240, operates contact fingers, part 258, (Fig. 39), connecting the elevating motor, part 65 (Fig. 22), to thl circuit for the proper direction of rotation. The projector the~ immediately begins to rotate by means of the worm, part 308~ the worm gear, part 67, and the spur gears, parts 68, 69 and 48, the gear, part 48, engaging with the elevating rack, part 22 (Fig, 35). The projector, through the bevel gears, parts 70, 219 an~ 220, the latter engaging with .the gears inside the cam cylinder: rotates the cam cylinder, part. 240, in a direction opposite thE direction of rotation caused by the pilot motor; the movement OJ the cam cylinder being the resultant of the movements induce by the rotation of the pilot motor field ~nd the rotation of th projector. . . ~ Summary.-These movements have been described sepa rately. As a matter of fact they occur simultaneously. Thl instant the pilot motor field moves, the elevating motor is cori nected to the circuit and rotates the projector, which in turl tends to rotate the cam cylinder back to the off position. j 'Vhen the controller hand wheel is advanced through sever~ revolutions and stopped, the pilot motor field revolves, advancin the earn cylinder, which, in turn, connects the elevating mo~o
A circuit b~eaker controls the entir.e current for the b~ar • except that earned by the double pole smgle throw fused sWltch,~ at the upper left hand corner of the switchboard, which is wired outside the circuit breaker, or across the line between the sourcl of supply and the circuit breaker, and supplies the station lightsl~ At the upper right hand comer of the switchboard a doubl pole single throw .used switch controls the current passinl through the feeding magnets of the lamp, the field and armatur~. currents for the elevating and training motors and current for the pilot motors, which is delivered through the' contact cYli.nder/ in the controller. .' The occulting switch in the center of the switchboard short circuits the extra or occulting resistance contained in the rheostat' this switch being marked "Open to occult light.'" The ammeter indicates the amount of current passing through the lamp, and the voltmeter, by means of the small switch located t beneath it, will indicate the voltage of the supply circuit wherEl it enters the switchboard, or the voltage across the carbons 0 the lamp, the positions of this switch for indicating the line anJ arc voltage being marked on name plate above the switch Directly below the ammeter is a receptacle into which the at each1'" ing plug of the portable lamp may be inserted.

as its presence in the barrel is detrimental to the silvering. The beam should not be elevated above 30°, as hot carbon particles might drop on the mirror and crack it. . Clean the mirror as follows: Rea:ove all dust with a dustbrush and then polish with a chamois skin. If the mirror . hecomes dirty or greasy, clean with the following preparation: ! parts precipitated chalk (by volume), .! parts water, 2 tablespoonfuls alcohol to a quart of the preparation. The preparation should be applied carefully with a sponge and in Yery .small quantities, polishing when dry with a piece of clean cheesecloth. Never use anything which will scratch the face of ~he mirror. ' In removing the lamp Model 1910 from the barrel lock the barrel with the st~ut (part 47, Fig. 36, Part II.) which engages with the pin on the locking rack. \Vhen the carbons are redhot, first remove the hot carbons with the door open 45°. If the door is swung open 90° the hot carbons may crack the middle glass strip. . When operating the lamp-feed by hand, insert a wooden gauge between the feed-together-arrnature of the feeding-magnet and the leg of the lamp, for the purpose of keeping the feedtogether-pawl out of the engagement with the ratchet. When the light is not in operation, keep it cmiered with a canvas cover.
