The lamps were mounted on the movable carriages in the same source compartments described in Chapter III. By means of the double switch shown in the wiring scheme it was possible to alternate between the two lamps the slow and rapid flashes. The revolving disk is illustrated in this figure as much too large when compared with the illustration of the motor. The worm gear reducer, described in the text, is not shown in the illustration. lamp connected through the right pair of points would have on and off intervals twice as long as the intervals of the other lamp. But, for any period of time, the total of the 07i or off time of the one lamp would equal the same of the other lamp. Similarly, the on and off flashes of the one lamp could be divided so that the intervals were one-third or one-fourth of the intervals of the other Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Baltimore [etc. ], William & Wilkins Co.
