  • Patent number: 4696086
    Abstract: A die set for assembling badges and buttons includes a punch and two dies. The badge shell and artwork are loaded onto the first die. The punch descends during a loading stroke to load the shell and artwork therein by friction. The second die is positioned under the punch, and the punch descends during an assembly stroke. The punch includes a block attached to the assembly machine ram and a spring loaded punch ring. The second die has a base a spring loaded crimp ring. The punch ring abuts the crimp ring during the assembly stroke. The punch block descends further, but the punch ring remains stationary against the crimp ring springs. The shell and artwork are thus partially pushed out of the punch and into the second die. Continued downward punch block motion overcomes the crimp ring springs and causes both the punch ring and crimp ring to move downwardly together, thereby pushing the shell and artwork over the badge back.

  • Patent number: 4471713
    Abstract: Floor treating apparatus, principally for waxing floors includes a drip pan to catch wax from the applicator pad when the applicator head is in a retracted position. A piston pump has an adjustable variable stroke to provide selection of the quantity of wax to be deposited. Slotted connections between the applicator head and the supporting arms provide independent vertical movement of each end of the applicator pad to enable the pad to conform to uneven floors.
