  • Blind rivet and method of making same
    Patent number: 6224310
    Abstract: A self-plugging blind rivet for securing together apertured members comprises a tubular shell (11) having a tail end fact (16) at one end, a pre-formed radially enlarged head (13) at the other end, and a stem which extends through the shell and has a stem head (22) adjacent the tail end fact (16) of the shell. The region adjacent the stem head (22) is of increased diameter relative to the rest of the stem shank and has a plurality of axial depressions (26) formed therein, the corresponding region of the shell being arranged to fill the axial depressions (16) in the stem and being harder than the material of the shell (11) in a region adjacent the radially enlarged head (13). In use and under axial compression leading of the shell (11), the shell (11) buckles in the region adjacent the member remote from the performed head to form a blind head in contact with said member so as to clamp together the apertured members.

  • Valve for a fluid dispenser
    Patent number: 3970225
    Abstract: A dispenser pen for dispensing liquids such as adhesives has a tube 12 connecting a supply 14 of the liquid to a nozzle 15. The tube 12 passes between a cross-pin 19 and one end of a pivoted lever 18 which is normally urged by a spring 23 to squeeze the tube 12 between the lever and the cross-pin so as to close the tube to flow of the liquid. The region 17 of the tube between the lever 18 and the cross-pin 19 is predeformed to a generally flattened shape which can open to permit flow of liquid but can be closed with little force and by a short movement of the lever 18.
