  • Patent number: 5529233
    Abstract: An apparatus for dispensing plastic fasteners from fastener stock includes a gun shaped casing. A hollow needle having an inlet opening is mounted on the casing. A guide groove is formed on the casing for receiving the fastener stock, the guide groove being in communication with said inlet opening in said hollow needle. A feeder element for intermittently advancing fastener stock loaded into the guide groove is mounted on the casing. An ejector rod is provided for pushing plastic fasteners from the fastener stock through and out of the hollow needle one at a time. The ejector rod and feeder element are driven by a DC motor powered by a battery pack removably mounted in the casing and which contains rechargeable batteries. The battery pack includes a receptacle which is arranged to enable the batteries to be recharged with the battery pack in or out of the tool.

  • Patent number: 5320269
    Abstract: An apparatus for dispensing an individual plastic fastener from continuously connected ladder stock including an elongated side member having a plurality of T-bars interconnected by severable connectors. In one embodiment, the apparatus includes a hollow, gun-shaped casing having a barrel portion and a handle portion. The front end of the barrel portion has an opening into which a hollow slotted needle is removably mounted. A triggering mechanism, which includes a pivotally-mounted trigger, is connected to the handle portion of the casing. A slider assembly, which is actuated by squeezing the trigger, includes a slider adapted to travel along longitudinally extending rails formed along the inside of the barrel portion of the casing.

  • Patent number: 5305939
    Abstract: A needle for use as part of a fastener dispensing tool adapted for dispensing plastic fasteners of the type typically used to attach tags to products for marking and identification. In one embodiment, the needle is made from a single sheet of metal by a stamping and/or rolling technique, and comprises an elongated, generally cylindrical, hollow, slotted member having a stem portion and a base portion. The stem portion terminates at its front end in a relatively sharp tip. The base portion, which is sized and shaped for insertion in an opening in the nose of the tool, includes a pair of outwardly extending, spring biased tabs. A first portion of one of the tabs is sized and shaped to releasably engage a recessed area formed in one of the walls of the opening so as to prevent unintended removal of the base portion from the opening and to limit rearward insertion of the base portion into the opening.

  • Patent number: 4284399
    Abstract: A two piece contact lens mold having a pair of blunt, continuous mating surfaces extending around the periphery of the mold cavity is disclosed. Location of the mold parting line tangent to the lens edge substantially eliminates registration problems when a relief groove is provided at the edge of the female member. Parameters for mold materials and important dimensions are also disclosed. The mold can produce finished contact lenses which do not require further machining.
