Per Bthrough the earth, and that it is desired to utilize the se impulses in accordance with my method. be the case, for example, when such a generator is used for purposes of signalling in one of the ways before enumerated, as by having its terminals connected at two points of the earth distant from each other. In this case the plates P and P' are first connected to two properly selected points of the earth; the speed of rotation of the cylinder A is varied until it is made to turn in synchronism with the alternate impulses of the generator, and, finally, the position of the brushes, and b, is adjusted by angular displacement, as usual, or in other ways, so that they are in contact with the segments and s' during the periods when the impulses are at, or near, the maximum of their intensity. - Conto Only ordinary electrical skill and knowledge are required to make these adjustments, and a number of devices for effecting synchronous movement being well known, and it being the chief object of my present application apparatus embodying a general to set forth a novel principle, a detailed description ovel princip de ta of such devices is not considered necessary The above requirements being fulfilled, electrical charges of the same sign will be conveyed to each of the condenser terminals as the cylinder A is rotated, and with each fresh impulse the condenser will be charged to a higher potential. The speed of rotation of the cylinder d being adjustable at will, the energy of any number of separate impulses may thus be accumulated in potential form and discharged through the receiver R upon the brush k coming in contact with one of the segments 1.
