Abstract: A leakproof joint construction for a pair of members disposed in abutting relation and method and apparatus for making the same are provided, the leakproof joint construction having part of one of the members deformed into an adjacent part of the other of the members so that the parts of the members are disposed completely beyond the plane of the outer surface of the other member while respectively being integrally interconnected to the remainder of the members by tubular portions of the members. The parts are interlocked together by an outward staking of the part of the one member into the tubular portion of the other member by a compaction of the parts, the parts and the tubular portions of the members respectively defining like polygonal configurations.

Abstract: An apparatus is provided for joining two metal members together with a lancing and staking operation that comprises the lancing and forming of a part of one of the members through an unblanked part of the other of the members and thereafter the staking of the formed part of the one member to an adjacent surface of the other member to secure the members together in abutting relation, the apparatus having a punch and a reciprocating head that cooperate together to form the lancing and staking operation on the members and having an indexible carrier for indexing the members to the head for the lancing and staking operation thereon and then away from the head after the lancing and staking operation, the carrier supporting and carrying the punch therewith. A method of making such apparatus is also provided.

Abstract: An apparatus and method for forming electrical switch assemblies each of which comprises a terminal member and a switch blade secured together at a station in the apparatus. The apparatus has a first feeding unit for feeding an elongated strip of switch blade material to the station, the apparatus having a forming unit for forming the strip of switch blade material into a plurality of switch blades serially interconnected together upstream from the station. The apparatus has a second feeding unit for serially feeding terminal members to the station, the apparatus having a securing unit for serially securing a terminal member and a switch blade together at the station. The apparatus has a separating unit for serially separating each switch assembly from the strip of material downstream from the station.

Abstract: An apparatus and method for forming an electrical switch assembly by lancing and forming a part of a terminal member through an unblanked part of an L-shaped switch blade member and thereafter staking the lanced and formed part of the terminal member to an adjacent surface of the switch blade member to secure the members together in abutting relation, the apparatus and method having a single reciprocating head that performs the lancing and forming step on a first stroke thereof and performs the staking step on a second stroke thereof. The head reciprocates substantially vertically beneath the abutting members, the head having a top portion for receiving one leg of the L-shaped switch blade and having a side against which the other leg is disposed. The method and apparatus has an arm for holding the other leg of the switch blade against the side of the head.
