CHARLES F. SPLITDORF, OF NEW YORK, N. Y.
CONDENSER.
SPECIFICATION forming part of, Letters Patent No. 728,780, dated May 19, 1903.
Application filed August 4, 1902. Serial No. 118,230. (N0 model.)
To a, whom it may concern.- 7
Be it known that I, CHARLES FREDERICK SPLITDORF, a citizen of the United States, residing in the borough of Manhattamcity, county, and State of New York, have invented a new and useful Improvementin Condensers, of which the following is a specifica- Lion.
This invention relates to condensers forin- (l notion-coils in general, although it is intended by me to be used primarilyin conjunction with coils of the jump-spark order, its characteristics being a compact circular form, en abling its inclosure adjacent to a coil within a common cylindrical casing, together with a special facility and economy of manufacture not hitherto attainable.
In brief, my improvement consists in forming into a roll a series of superimposed strips which are alternately positive and negative condenser elements .and are composed, as is usual, of tin-foil or the like. Between each pair of such strips is interposed an insulating-strip of paper or other dielectric, these latter having a relatively greater width to extend beyond the side edges of the condenserstrips, and thereby properly insulate the positive and negative elements from each other;
Lengthwise the arrangement of the metal and paper strips is such that corresponding ends of all the positive metal strips project beyond the paper and are in electrical connection,
and the opposite ends of the negative metal strips likewise project beyond the paper strips and are in electrical connection. Thus one end of the series of strips is composed of contacting laminae of positive sign, while the opposite end of the series is composed of contacting laminae ofnegative sign. The laminae at one end, as the positive, are initially wrapped about a terminal, as a wire or metal rod, being either soldered or otherwise securely attached thereto. The whole laminated bundle, comprising the positive and negative strips and theintermediate dielectric strips, is then wound tightly and compactly upon itself in convolute form about the terminal core to produce a roll of a desired thickness, according to the length of the strips employed. The respective outer ends of the negative strips, although conterminous when spread at length, are fanned out in the act of forming the roll, and I am therefore enabled to make contact with each one by means of a wire or metallic strip which I now wind tightly around the roll, binding it together, the said strand thereby forming the opposite terminal of the condenser.
In the drawings accompanying this application, Figure l is'a plan perspective view of the condenser elements prior to their being rolled into finished form. Fig. 2 is a longitudinal section through the line 2 2 of Fig. 1. Fig. 3 is a cross-section of the condenser, and Fig. 4 is a front view thereof.
In the figures the letter A indicates one of the condenser-terminals, as, we will say, that l of positive sign, and B indicates each of the metallic strips, also of positive sign, whose corresponding ends are connected, as at I), while the main body of the series is interleaved in succession with strips of insulating paper, as C or the like, and with other like metallic strips, as D. The ends of the positive metallic strips where connected, as at b, are wrapped about the terminal A, to which latter they are preferably secured, as by soldering, tolprevent displacement and effect close electricalunion therewith. The whole bundle of strips which are arranged in the order of the lowermost negative metallic strip then in succession an insulating paperstrip, a positive metallic strip, and an insulating strip. This series being repeated to comprise a condenser of the required capacity is then wound upon the core and itself in convolute form. It will be observed that whereas the insulatin'g'paper strips do not cover the ends of the metallic strips B at b they do cover and inclose the corresponding ends of the metallic strips D, which are of negative sign. Hence connection between the strips B and D is avoided at this point and efficient insulation provided. At the opposite end of the bundle the strips B lie short within the insulating paper strips 0, being covered thereby, while the ends of the negative metallic strips D project, as at d, and are in contact with each other. When the bundle has been rolled up completely, it will be found that the strips D, which were of equal length, have been fanned out at d in the process of forming the roll, so that as said strips lie upon the roll a small end portion of each one is exposed. I
now bind the roll tightly together With a wire or other metal strand or strip, as E, Winding the latter several times around the roll,whereby it is brought snugly in connection With the exposed edges of each of the metallic negative strips D, and thus forming a terminal for the negati\"e series.
Suitable portions of the respective terminals A and E may project for connection with an electrical circuit, as is obvious.
I claim A condenser composed of a bundle of alternately disposed metallic and dielectric strips, said metallic strips being alternately of positive and negative sign, one set of elements, as the positive, being free at one end and Wrapped about a terminal, said terminal G. F. SPLITDORF.
