is a wire 12, which i clucles e similarly shown fuse 13. These fuses may of course he of any opproveri construction,

Leading from the Wire intermecliete its ends is e Wire 1 1- Which connects with the plate 15, between which anal the opposed plate 16 is interposed a member 1'? formed of high resistance material This high resistence material may consist of e cerhorun cl'urn, silicon, or carbon composition held in suitable high resistance cinder, end of course in electrical connection with the plates and 16, said plates being formed. of e conducting material, and Wire 18 leads from the plate 16 to 3V -ire 19 which con-- nects with the binding post Leading from the wire 1 intermerliate ends is :1 Wire 26, the some connecting with a plate 21, similar in all respects to plate 15 encl between this plate and o similar plate 22, is a resistance materiel plate 22 being connected by means of Wire 52% with the common Wire 1% Plates 15 and 1f'3, in the present instance, are provided "with. opposed points 25 anti 26, which extend toward each other but terj inete short of contact so as to form an gap thercbetwcen. Similarly, the plates 21 end 22 are provided with the contact points and 28, between which is formed on air All of the plates 15, i6, enol 21, 22, may be readily bent, or otherwise menipm letecl to ecliust the points 25, 25, end 2?, 28, farther apart or closer togctl'ier, so as to determine the amount of voltageet which the air gap will creek down. I

Having thus described the construction of this embodiment of .rny invention, the operation thereof may now he umlerstoml. By reason of the provision of the high resistmice materiel hetvveen the line and grounci, relatively small static discharges coming over the line are taken care of without are ing; since such discharges will pass through the high resistance material in or :l cience to the air gap. Therefore, since there is no arc, there is no'tenclency for particles of carbon or other material to hecorne clielodged and form apermanent connection between the line and grounil However" when unusual discharges of relatively high potential are discharged between the line and ground, such discharges will take place through the air gap provided between the opposecl contact points 25, 26 and 27, 28 lmvino' the hil 'li resistance material intact,

and thereby insuring against a permanent ground connection between the line and ground. lt Will accordingly be seen that l. have pronded means Wl'uch While fully protecting the line against discharges of is be little likely to become'disarraiiged, and which wil require a minimum exercise care and attention, and at the same time is of a very simple construction.

its many c ges could be made in the above con ruction and many apparently widely different embodiments of this invendon could be made "Without de 'iartiug from he Sci/D6 thereof, it intended that'all matter contained in the above description sh mi in the accompanying drawing shall be interpreted illustrative and. not i limiting sense. lit is also to be underu stood that the language used in the folloW- ins: claim' is intended to cover all of the eneric and specific features of the invention which as amatter of language, might be said to falltherebetween.

Having thus described my inrentiom whet claim as new and desire to secure by Let ters l atcnt is:

1. lo a lightning: arrester, the combination with a line and ground connection therefor, oi? a member of relatively low con- :y interposed between said line'and ground, and spaced. conductors providing an gap in multiple with said low conher high or low potential will, neverthe ducting member, said spaced conductors comprising a pair of members at least one of which is bendable whereby to adjust the degree of the resistance offered by the air gap and consequently for varying the maximum load to be placed upon the interposed low conducting member.

2. In a lightning arrester the combinzu tion with a line and a ground connection therefor, of a block of material of relatively lOW conductivity interposed between said line and ground having oppositely disposer substantially parallel faces, a pair of "Jlates of conducting material, one engaging each of said faces and having" parts extending substantially straight therefrom so that their outer ends are spaced apart to provide an air gap in multiple with said interposed block of material, and at least one of said plates being bendable whereby the outer ends of said olates may be moved to Ward or away from each other for varying the resistance ofiered by the air and consequently for varying the maximum load to be placed upon the interposed block of material.

In testimony whereof I have affiized my signature in the presence of two Nil/DQ515553 :eeou s. BEACH.
