2 Claims. (Cl. 175-41) The invention relates more particularly to condensers of the tubular type, that is where the active condenser elements are enclosed within a hollow or tubular insulating casing, and aims pari 5 ticularly to provide a. simple and economical construction of the above character wherein wire terminals are employed. Further objects and advantages of the invention will be in part obvious and in part specifically pointed out in the descripl tion hereinafter contained which, taken in conjunction with the accompanying drawing, discloses a preferred embodiment of the invention; such embodiment, however, is tobe regarded as merely illustrative. In the drawing- ,i

Fig. 1 is a longitudinal section showing the internal parts of a condenser made in accordance with the invention.

Fig. 2 is a longitudinal section of the complete device and Fig. 3 is a cross Sectional vietg'taken on the central portion of Fig. 2. v

The invention is illustrated as applied to a condenser having an insulating base member l, which carries dielectric strips 2 and conducting strips 3 and 4 respectively, which are of opposite polarity. The

strips

2, 3 and 4, for example, may be wound or rolled about the insulating member 1.

'I'he conducting strips 3 have portions 5 which extend beyond one edge of the dielectric sheets 2, at one end of the insulating member 1, and the conducting strips 4 have similar extending portions 6 at the opposite end of member 1.

The parts of the condenser above described are enclosed Within a tubular insulating casing 7, as shown in Figs. 2 and 3, and wire terminals 8 extend outwardly through the opposite ends of casing 7, these terminals being bendable in all directions but sufciently stiii' to support the condenser in any desired position.

The inner ends of the terminals 8 are mechanically clamped against the extending portions and 6 of the supporting strips; as shown rivets or eyelets 9 respectively extend through the opposite end portions of the insulating member 1, and the extending portions 5 and 6 of the conducting strips, these rivets being headed over to hold the terminals 8 in good electrical contact with the conducting strips. Preferably the terminals 8 are also interengaged with the respectively adiacent portions of the insulating member 1, to assist in keeping them in proper position. As shown at the right of Fig. 1, terminal 8 may be passed through an opening 10 in the insulating member 1 for this purpose, or may be coiled around the adjacent portion of the insulating member 1, as

Vjacent portions of said first mentioned insulating Vof Figs. 1 and 2.

Preferably the ends of insulating casing 'I are closed by fasteners 12, as shown in Fig. 2, and the space within the casing '7 may be filled with 60 suitable insulating composition 13 (Fig. 3).

While a specfic embodiment of the invention has been described, it should be understood that changes may be made therein, without departing from the invention, within the scope of the appended claims. 1

I claim:

1. An electrical condenser comprising an elongated insulating member, alternating dielectricV and conducting strips overlying an intermediate portion of said member, different conducting strips respectively extending beyond opposite edges of said .dielectric sheets, a tubular insulating casing enclosing the above mentioned parts ofthe condenser, wire terminals extending through the opposite ends of said casing, the inner portions of said wire terminals respectively overlying the extending portions of said conducting strips, and clamping members respectively engaging said wire terminals and passing through the respectively adjacent portions of said iirst mentioned insulating member and extended portions of said conducting strips for electrically connecting said terminals respectively with the extending portions of said conducting strips.

2. An electrical condenser comprising an elongated insulating member, alternating dielectric and conducting strips overlying an intermediate portion of said member, diierent conducting strips respectively extending beyond opposite edges of said dielectric sheets, a tubular insulating casing enclosing the above mentioned parts of kthe condenser, wire terminals extending through the opposite ends of said casing,-the in- 5 ner portions of said wire terminals respectively overlying the extending -portions of said conducting strips, and rivets engaging said wire terminals and passing through the respectively admember and extended portions of said conduct- 00 MAR'rm n.
