This invention relates to a lightning arrester of the cartridge type in which there is provided a. plurality of spark gaps for msuring. a high degree of rehability and pro- '5 tection, and it is therefore the principal object of my invention to provide a lightning arrester which has a pluralit of spark gaps so arranged as to insure relia ility of action, and therefore a high degree of protection to the devices connectedto the line with which the arrester is associated. Other objects will i be apparent upon a stud of the specification,
taken in connection wit the annexed drawin in which:
igure 1 is a plan view of the arrester with the casing broken away and showlng certain of the parts in section.
metal inwardly so as to form abutments for the heads 4 of insulat in material. Associated with the outer sur ace of each of the hollow stud 9 which passes through the head 4, and has its end 11 spun over a washer 10 so as to draw the head 12 of the stud into .secure engagement with the plate 7. The head 4 is held in the end of the shell by crimping the end 15 of the shell 1 over the. inwardly turned edge 8 of the washer 5. This constructioii, therefore, connects in series the two spark gaps carried at opposite ends of the arrester.
The head 4is provided witha recess which is not shown in the section taken, and the end of the shell 1; ispushed inwardly, as in- These ar-fl 'rester elements are held in position by a x 1988. Serial No. 377,007.
dicated at 22 (see 2) to enter the said recess, thereby preventing the head 4 from turning within the shell. It may be noted that the shell 1 is preferably provided with a small openin opposite the gap 18, so as to permit inspection of the operation of this gap, if so desired. Since the shell 1 is broken away at this point, this opening does not show in the drawing.
Mounted within the shell 1, is a sealed chamber 23 within which are positioned electrodes 16 and 17, forming a s ark gap 18. Preferably, the electrodes 16 an 17 are made up of a plurality of twisted conductors of suitable material which are bound together adjacent the spark gap 18 by binding plates 19 and 20. The chamber 23 may be of any suitable material such as glass, which is hermetically sealed, and in certain cases, a partial vacuum may be produced within the chamber 23, or the chamber may be filled with some inert gas such as neon. In either case, the pressure within the chamber 23 is 'such as to permit the passing of an electrical current at a comparatively low voltage.
The electrodes 16 and 17 extend outside the chamber and are adapted to ass through the hollow studs 9, and are sol ered as at 14, to the heads 12 of the studs, a recess 13 bein provided to assist in making a good soldere connection at this *point. The thickness of the mica insulators or spacers 6, is chosen so that the voltage to jumpthis gap is somewhat higher than the voltage required to jump the gap 18 within the sealed chamber 23:
In ordinary operation of the arrester, the
pair the operation of the gap 18, then the spark ga s at the ends of the arrester will take the 'scharge'. In case of unusual lightning disturbances, all of the spark gaps may be brought intoo eration, even though the aps at the ends 0 the arrester are connected in seriesmultiple with the gap 18; 7
From what'has been said, it willbe readilg understood that the two seriesgaps connecte in multiple with the main arrester gap within the sealed chamber, provide an auxiliary pro tection which is of considerable value, as these arresters are frequently installed on circuits where it is not safe to depend on one gap.
