Book Description
This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1905 edition. Excerpt: ...anyone operating the controller unless he is in possession of the power handle. To operate the controller the power lever must be pushed slightly forward to position P.L. 2 (see Fig. 57). By this movement the speed lever is unlocked, and can be brought back to the position of maximum field strength of the motors. The power handle can then be moved to P.L. 3 so as to allow current to pass through the motor armatures, and start the car slowly on the resistances. During this movement of the power handle the speed lever is locked, but when the power handle reaches the "on" position P.L. 4 the speed lever can be pushed forward, and by reducing the strength of the field magnets causes the car motors to run faster. The controller cover has notches which can be marked with numbers indicating the speeds at which the car will travel, and if the lever is allowed to remain at any particular notch the speed will remain practically constant whether running up hill or down. s s 50MP qwinp 1 1--WHP 58!8!--1 f f _f Diagram Showing Arrangement Of Armatures And Fields. To brake the car or control its descent down inclines the speed lever is pulled back notch by notch according to requirements. To reduce the speed below the minimum given when the speed lever is at full excitation position the armatures are short circuited through resistances on position S.L. 4, and power handle on P.L. 2. In addition to the shunt winding the motors are furnished with a few series coils, so that in emergencies, such as the trolley leaving the wire and the shunt excitation failing, the series coils can be brought into operation, and the car pulled up by this means. This emergency brake position is shown at S.L. 5, where the speed lever is pulled back to full extent....
