Abstract: An anti-pickpocket device for preventing a wallet from being removed from a pocket without the wearer's knowledge by creating a drag on the wallet. The device consists of a plurality of downwardly-projecting prongs pivotally mounted on a flat base which are urged outwardly therefrom by resilient means. An inflatable tube is mounted in the base which, upon inflation, rotates the prongs into a flat disposition with respect to the base for unimpeded withdrawal of the wallet. A small hand pump in fluid communication with the expansible tube by means of flexible tubing and a pressure relief valve are provided for selective inflation and deflation of the expansible tube for controlling the orientation of the prongs.This is a continuation-in-part of copending application Ser.

Abstract: The present invention pertains to a power integrated sequential timing and drive mechanism for operating the forming unit of a hand held powered metal clinching tool through a cycle beginning with a normally open position and passing through a clinching position and return. The drive mechanism, which is interposed between a forming unit and a suitable power source such as a reciprocating pneumatic motor comprises a driving arm which is pivotally mounted to effect a multiplication of the force generated by the motor on a punch which comprises a portion of the forming unit. A slave arm is disposed opposite the driving arm and is operable in conjunction therewith by means of an interconnected collapsible link disposed between the two.
