SPECIFICATION forming part of Letters Patent No. 774,115, dated November 1, 1904.

Original application filed J une 13, 1903, Serial No. 161,325. Divided and this application filed October 19, 1903. Serial No. 177,636. (No model.)

To @ZZ whom t may con/cerrar Be it known that I, JOHN SPLrrDoRF, a citizen of the United States of America, and a resident of the borough of Manhattan, in the city, county, and State of New York, have invented certain new and useful Improvements in Condensers, of which the following is a specification.

This invention relates to an improved electrical condenser, being a division of my application, Serial No. 161,325, filed June 13, 1903, and it includes a novel structure of condenser or relative arrangement of the several elements thereof adapted to promote an improved facility of charging and discharging.

In brief, my improved condenser may be described as composed of continuous alternate conductor-strips, each separated by a dielectric or insulating strip and formed into a roll, opposite outside edges of the conductor-strips beingexposed,respectively,beyondtheoutside edges of the dielectrics and the opposite inner edges of said conductor-strips being lapped overtheinterveningdielectrics. Maintaining strictly this relative arrangement the several strips are disposed in the order of a dielectric, a conductor of one sign placed thereagainst with its inner edge lying within one lateral boundary of the dielectric and its outer edge extending exposed beyond the opposite lateral boundary of said dielectric, a second dielectric disposed against said conductor in contiguity with said irst dielectric, and a second conductor of opposite sign placed thereagainst with its inner edge lying within one lateral bound ary of said second dielectric and its outer edge extending ex-posed beyond the opposite lateral boundary of said second dielectric. Thus the opposite conductor-strips of corresponding width are spread laterally against the respective surfaces of an intervening dielectric strip. In a roll formed of these members another dielectricis added, being placed against that conductor which is to lie inwardly in the roll formation, whereby in the second turn it lies upon and insulates the other conductorstrip. Thus it will be seen that throughout the various convolutions the conductor-strips of opposite sign have an unlike but uniform conitiguity with the dielectrics. In a roll of derollof the component elements comprising my improved condenser. Fig. 2 is a view of the same as ilattened out, and Fig. 3 is a perspective plan View of a pile of conducting and dielectric strips forming a condenser.

Inthe gures, A indicates a tube of collapsible material, as pasteboard or the like, which latter is intended to form a core for the condenser.

B indicates a strip of paper or other dielectric wound upon the tube A. O indicates a strip of tin-foil or other conducting material, D a strip of paper or the like, and E another strip of tin-foil or thelike. The arrangement of the said strips B O D E and the manner in which the same are wound upon tube A are as indicated in the drawings-that is to say, one being placed against the other in the order named and all wrappedabout the core, or said order may be modified within the bounds of practicability. 4

The particular relative arrangement of the respective elements in forming the condenser is clearly shown in Figs. 1 and 2, Where it is seen that the two dielectrics are in like (though separated) contiguity throughout the bundle and that the opposite conducting-strips lap each other over an intervening dielectric throughout the bundle, thus providing for induction, but said conducting-strips, respectively, extending laterally beyond the dielectrics, at opposite sides thereof, to provide terminals of opposite polarity.

When a condenser of desired capacity has been Wound upon the tube A and its free ends An improved condenser consisting of two continuous conducting-strips and an intervening dielectric rolled into a bundle whose opposite terminals allow connection with a source of electricity whereby the discharge will be across the roll instead of lengthwise of said strips.

Signed at New York this 5th day of Octo- 20 ber, 1903.
