Abstract: A personal transporter includes a tubular metal frame supporting a platform for supporting an operator, and the frame has forwardly projecting and parallel spaced inverted L-shaped frame members which support a pair of freely rotating front caster wheels. A pair of reversible electric motor and attached gearbox drive units are mounted on the rear portion of the frame on opposite sides of the platform, and the gearboxes have right angle output shafts forming axles supporting a pair of rear wheels. A storage battery is enclosed within a box in front of the platform, and a vertical adjustable post projects upwardly in front of the box to support a handlebar. A hand control unit is mounted on the handlebar and is connected to the drive units through a control system within the box. The rear wheels are covered by fender guards which also cover the drive units.

Abstract: A pair of circular cutting dies each has a sharp peripheral cutting edge surrounding a cavity, and a connecting pin extends through center holes within the dies to support each die for rotation. One projecting end portion of the pin has a cross hole receiving a key ring, and the opposite projecting end portion receives a cross pin pivotally supporting a thumb actuated cam lever for forcing the dies and cutting edges together to a cutting position against the biass of spring washers confined between the dies within the opposing cavities. The lever is movable between a die open position and a die locked position for holding the dies in a closed position.

Abstract: A device for facilitating the welding together of pieces of welding wire comprises a pair of complementary vise units which are connected together for relative linear movement and are spring-loaded toward a limit position in contact with each other. In use, two pieces of welding wire are clamped in the respective vise units in such relative positions that they are in end to end contact while the vise units are separated from their limit position against their spring loading. Welding current is then applied to the junction of the wires until they are sufficiently softened for the spring-loading of the device to force their softened ends together and thereby to complete the welded joint therebetween.
