Bias-type Member Holder Patents (Class 227/149)
  • Patent number: 4753382
    Abstract: This invention relates to an apparatus for inserting components into workpieces, particularly for insertion of electrical components into printed circuit boards. Multiple component magazines are provided on a shuttle which places the desired component beneath an inserter. The inserter moves through a limited reciprocation to pick up a component from the shuttle, and the shuttle is withdrawn from the path of the inserter. The inserter then moves downward to insert the component. The inserter includes an ejector which maintains contact with the inserted component during withdrawal of the inserter. The ejector includes a shock absorber which gives way if unusual resistance is met during insertion. The shock absorber is spring-biased, and the degree of stiffness of the spring is adjustable.

  • Patent number: 4651912
    Abstract: The tool has a reciprocating barrel mounted in a housing and includes a ram mounted in the barrel for driving a fastener into a work surface. The firing mechanism has a firing pin and a firing pin driver which the operator strikes with a hammer to fire a cartridge chambered in the tool. The firing pin driver is biased to a retracted safe position when the tool is not cocked so as to prevent drop fire. A detent pawl is mounted on the ram to provide frictional retention forces for the ram and barrel. The pawl cooperates with a resilient stop mounted on the housing to return the ram from a driven position to a driving position when the barrel is reciprocated in the housing, and the pawl also engages a breechward stop formed in the housing which prevents the ram from contacting a chambered cartridge when the tool is in a breech-closed, ready-to-fire condition. Bellville washer stacks are used to position the firing mechanism. An improved hand grip is also provided.

  • Patent number: 4533077
    Abstract: A setting device includes a driving piston propelled by high pressure gases through a casing for driving fastening elements into a receiving material. A stop device located within the casing secures a stop element in a recess in the driving piston for holding the piston in the firing position. The stop device includes a first spring and a second spring each biasing the stop element into the recess. The first spring has a greater biasing force than the second spring. To release the driving piston from the firing position so that it can drive a fastening element into a receiving material, the propelling forces acting on the piston displace the stop element against the force of the springs and then the first spring biases the stop element against the second spring. After the stop element is displaced out of the recess only the second spring acts on the stop element so that movement of the driving piston relative to the stop element is effective without any appreciable holding action limiting such movement.

  • Patent number: 4519534
    Abstract: A machine for driving a pin into a hole in a work piece. The pins are fed by gravity in a continuous succession from a pin supply to a passage extending through a pin receiving rotor. With a pin in the rotor, the rotor is turned through a selected angle to bring the pin and the passage through the rotor into alignment with a pin driving punch. Upon actuation of the punch, the pin is driven from the rotor into a passage in an adjacent aligned sliding pin guide. Movement of the pin through the pin guide temporarily ceases when the pin encounters a resilient stop. Continued movement of the punch then moves the pin guide and the pin therein until the nose of the pin guide engages the work piece. The punch, continuing to move through the passage in the now stationary pin guide, drives the pin past the resilient stop and into the aligned hole in the work piece. Upon withdrawal of the punch, the pin guide aided by a spring returns to it original position adjacent the rotor.

    Abstract: A hand-held driver tool is disclosed for holding and aligning the axis of elongated fastener with another axis such as the axis of the tool or such as an axis through a pair of apertures in upper and lower belt fastener plates and an aperture in an underlying anvil support means. The preferred driver tool comprises a housing means with an elongated bore within one end of which there is received an expandable chuck means and within the other end of which there is slidably received a driver means. An elongated fastener such as a rivet-nail is inserted within the bore and into the chuck for being driven into a piece such as a belt upon an impact force being applied to the driver. A cone-shaped end on the lower end of the tool is inserted into a cavity in the belt fastener and a cooperating flange abuts the belt fastener to align coaxially the apertures and the axis of the elongated rivet-nail assembly.

  • Patent number: 4060189
    Abstract: The invention relates to slug riveting apparatus wherein a pair of opposed rivet head forming anvils move relatively toward each other to form heads at the opposite ends of a cylindrical rivet blank, more or less simultaneously, after the blank has been inserted in the workpieces. An annular elastomeric polyurethane member is associated coaxially with one of the rivet head forming anvils and has a bore for receiving and resiliently gripping a cylindrical rivet blank. The elastomeric annular member holds the blank during insertion of the blank in the workpieces as the anvils move relatively toward each other, and the rivet blank is moved out of engagement with the elastomeric annular member by the associated head forming anvil during the head forming operation by resilient radial expansion of the elastomeric annular member. The rivet forming anvils have flat bottomed head forming recesses with sloping side walls.

  • Patent number: 4003417
    Abstract: A self locking and unlocking clamp for use in cooperation with an automatic fastener driving tool. The clamp includes a fastener receiving head having a pair of jaw members pivotably mounted thereto. The jaw members are operated to securely hold individual fasteners along their central axes while they are being attached to or driven into a workpiece. A trigger assembly and a cooperating locking assembly is provided on the clamp for (a) locking the jaws together in order to securely hold successive fasteners relative to the tool, and (b) unlocking to enable the jaws to move apart and thereby release successive fasteners once they become securely attached to a workpiece.

  • Patent number: 3998372
    Abstract: Power-operated tools require an adaptor for holding in place a clip while the tool projects a fastener through the clip to fasten it to a ceiling or other structure. This improved adaptor is held on the barrel of the tool by a connection that permits the clip or the tool to be rotated into the most advantageous position, and the adaptor has a simple and easily manipulated retainer for holding the clip.

  • Patent number: 3960307
    Abstract: Disclosed is an apparatus for attaching an ornament by a pronged setting to sheet material, which includes a base having an anvil in the form of a turret on which the sheet material is placed and a pivotally connected head which receives the setting. A plunger on the head registers with the anvil when the head is pivoted relative to and toward the base. The plunger comprises a sleeve and a punch reciprocable axially within the sleeve. The sleeve contacts the sheet material and holds it in engagement with the anvil, and the punch moves axially within the sleeve to force the prongs of the setting into and through the sheet material and to deform the prongs so as to fasten the ornament to the material. A spring is disposed between the sleeve and the plunger to permit relative axial movement therebetween and to bias them apart after the ornament has been affixed.

  • Patent number: 3934779
    Abstract: An improved fastener driving tool having particular utility at locations that are otherwise inaccessible is disclosed. The fastener driving tool of this invention includes an elongated cylinder having one closed end. A ram is slidably mounted in the cylinder so that one end of the ram bears against the inside surface of the closed end of the cylinder. An axially displaceable rod is mounted on the outside surface of the cylinder and includes a clip that is adapted to hold the head of the nail against the outside surface of the closed end of the cylinder. With the nail so positioned the tool may be inserted behind a wall, for example through a pre-existing window opening, so that a header may be secured to a stud. By using the tool of the present invention, it is not necessary to remove any plaster or wallboard in order to expose the header and studs that are to be nailed. The ram is moved axially in two opposite directions within the cylinder until the nail is sufficiently started.
