  • Patent number: 4468553
    Abstract: Welding of similar and dissimilar metals such as fine wires of gold, silver, brass and others to provide required strength without marring the surfaces of the link is accomplished by mounting an electrode (75,264) a selected distance from the surfaces to be welded. A first high voltage ionizing arc of a selected atmosphere between the electrode and the surfaces to be welded is followed by a low voltage, high amperage welding arc. An electrode (75) is mounted in a discontinuous link forming machine (10) so that it can be oriented in optimum position relative to the work piece (9). An electrode (264) is mounted in an automatic chain making machine (200 ) so that it can be optimally adjusted in x and y directions employing target adjustment block 320, as well as in the z direction employing vertical adjustment block 290.

  • Patent number: 4461471
    Abstract: A walker comprising spaced, parallel frame members defining spaced, parallel handrails supported by pairs of legs with wheels at the lower ends of the legs, manually-operable linkage operable to mobilize and demobilize the wheels at the lower end of at least two of the legs, characterized in that the frame members are interconnected by linkage which enables folding the frame members into overlapping parallel relation to each other.

  • Patent number: 4388513
    Abstract: An electrode (75) disposed within an insulating sleeve (86) is placed adjacent a work piece (9) to provide a selected gap between the electrode and the work piece. The atmosphere between the electrode and the work piece is first ionized and then a welding arc discharges between the electrode and the work piece. The orientation of the electrode can be adjusted by rotation of the electrode assembly (36), the amount of the gap by rotation of member (78), vertical placement of the electrode head 36 by eccentric means 40 and spacing between the terminus of the forward movement of arm (32) and the work piece station by adjusting the position of stop (54). Spacing of the electrode from the work piece enables the welding of similar and dissimilar metals such as fine wires of gold, silver, brass and others used in such applications as jewelry, medical, and electronic to provide the required strength, but without marring the surface of the work piece.

  • Patent number: 4215262
    Abstract: A percussion welder includes a single acting main cylinder having a ram extending through both ends of the cylinder mounting a spring loaded chuck on one end of the ram and an adjustable return spring on its other end.An automated version includes a hollow ram for the main cylinder through which a stud to be welded is blown from an escapement in a vibratory feeder bowl. The escapement has two spaced guide rails which receive the studs in a single column and a block which slides transversely across the end of the rails to pick off a single stud and move it into alignment with a gush of air which blows the stud head first through a tube to the hollow ram. A chuck having a stationary and a movable clamp is mounted on the opposite end of the ram. An actuator is disposed adjacent the chuck and opens the chuck to permit the stud to pass therethrough and at the same time places a platform beneath the chuck to prevent the stud from exiting the chuck more than a selected distance.
