  • Patent number: 4429456
    Abstract: An apparatus is disclosed for inserting elements into a workpiece. The apparatus includes reciprocating feeding means movable between first and second positions for sequentially advancing a supply strip of integrally connected preformed elements towards the workpiece. Actuating means cooperate with the reciprocating feeding means for rotating the reciprocating feeding means when the reciprocating feeding means has reached its second position. During the rotation, the supply strip of elements rotates with respect to the lead element which has been inserted into the workpiece thereby breaking the lead element from the supply strip. As the feeding means, holding the supply strip, rotates back to its initial position, the interaction of the supply strip and the lead element which has been inserted into the workpiece polishes and wipes away any burr that may have remained during the severance.

  • Patent number: 4075751
    Abstract: A hand-held tool includes a pair of oppositely-directed punch heads coupled to a pneumatic cylinder and piston rod unit by an expansion linkage. A finger-actuated lever on the tool operates a valve to supply compressed air to the cylinder and piston rod unit which actuates the linkage and drives the punch heads apart. Each punch head is provided with a tri-facial point for forming a detent in metal adjacent plastic. Part of the metal is torn at the detent and embedded in the plastic to couple the two elements together. When the lever is released, air is routed to reverse the action of the cylinder and piston rod unit.

  • Patent number: 4071949
    Abstract: A method and apparatus for securing spherical bodies to a supporting member by staking. The spheres are fed one by one into a bore of a setting apparatus where they are picked up by the front end of a staking punch which reciprocates in the bore. The punch advances the sphere to the supporting member and imbeds the sphere in the surface of the supporting member while at the same time forming integral tangs from the supporting member which partially encircle the sphere and hold it in place. The punch then withdraws to pick up a fresh sphere and a new supporting member is moved into place to receive the fresh sphere.

  • Patent number: 4064617
    Abstract: A die assembly for clinching a fastener such as a pierce nut to a panel. In the clinching operation, a pilot portion of the fastener is driven through the panel and into an aperture in a die body. Step portions of the die body deform the fastener pilot and interlock or clinch the fastener and panel together. After the clinching operation, the fastener and panel are stripped from the die assembly. In order to facilitate release of the fastener pilot from the die aperture, the die body is segmented so that its segments can separate in a radial direction to enlarge the aperture. The die body segments have sloping outer surfaces received in a complementary die holder so that the segments are cammed together during the clinching operation and are separable during the stripping operation.

  • Patent number: 4033499
    Abstract: A tool for driving staples or nails and simultaneously providing reinforcement therefore. The tool is particularly useful in installing roofing material, although it has equal utility in attaching labels, tags and the like to shipping cases, and siding to buildings, and other purposes.In a preferred embodiment, the tool is provided with a handle which is long enough that a workman may operate the tool without bending over any material amount. The staple or nail driving mechanism may be of the hand-driven type or may be air, electric or spring operated. Connected to the housing of the driving mechanism is a magazine containing a considerable number of fastener reinforcing elements, such as thin metal discs, through which the staple or nail is driven in the same stroke used to drive such fastener into the object to be fastened.

  • Patent number: 4028986
    Abstract: An elastomeric tip member for mounting on the piercing end of a nail-like fastener. The tip member has a forward end having means on its exterior for providing an interference fit with the wall of a hole through a bracket or the like into which the tip member is inserted. The tip member is preferably formed from a plastic material which will break up when the fastener is driven into a supporting material. The tip member thus provides an expendable temporary connection between the fastener and the bracket prior to driving the fastener into a supporting material to secure the bracket thereto.
