Patent ID: 8371206

Claim:
A make-break for a gun having breech and a wedge-type breech block, the make-break consisting of: (a) a stationary mass which provides a cradle upon which the gun is slidably mounted to allow the gun to recoil therein when fired; (b) a contact housing which is suspended downwardly from a mounting bracket affixed to a bottom of said stationary mass, which contact housing has a face plane which is oriented in the direction of recoil of the gun; (c) a first set of contacts comprised of a plurality of individual parallel elongated contacts, each elongated contact extending in a rampwise fashion from the face plane of the contact housing, with a portion of each contact closest to the bottom of the stationary mass extending a greatest distance from the face plane, and with a portion of each contact farthest from the stationary mass extending a least distance from the face plane; (d) a second set of contacts, comprised of a plurality of individual parallel fingers extending from a shoe affixed to a bottom of the wedge-type breechblock, which shoe is located such that the fingers of said second set of contacts will electrically contact with the first set of elongated contacts when the gun is in-battery and the breech is closed; and (e) whereby, when the gun is fired, the first set of contacts and the second set of contacts separate the make-break is thereby opened, and when the gun goes back into battery and breech is closed, the first and second set of contacts will align and again contact with each other.
