Blade storage and selectable force impact termination tool

A hand held impact tool for use in terminating electrical conductors at a terminal block, comprising

• an elongate handle,
• a slide assembly mounted in said handle yieldably urged toward a position extending from one end thereof,
• a hammer assembly mounted in said handle operating to deliver a hammer blow to said slide assembly,
• a drive spring seat member mounted in said handle,
• a hammer drive spring extending between said hammer assembly and said drive spring seat member urging said hammer assembly toward said slide assembly,
• a cam follower surface on said seat member,
• a cam bearing against said cam follower surface and mounted in said handle being movable relative thereto,
• movement of said cam operating to alter the compressed length of said hammer drive spring, whereby said hammer blow is greater when the compressed length is lesser,
• a pouch assembly in the other end of said handle,
• said slide and pouch assemblies being configured to accept termination tool blades including means for engaging the electrical conductors, each of said slide and pouch being independent of the other whereby to store one termination blade in said pouch assembly while, at the same time, another termination blade is mounted in said slide assembly for use in terminating the electrical conductors,
• and means in said pouch assembly for releasably retaining either of said termination blades therein,
• said pouch assembly comprising a storage cylinder movable rotationally relative to said handle and having a bore therethrough accepting the termination tool blade, said means for releasably retaining a termination blade comprising a coil spring mounted in said bore having one end thereof movable with said storage cylinder and having a diameter smaller than said storage cylinder bore and operating to engage the termination tool blade, whereby torquing of said storage cylinder in a sense contra to the spring coil direction expands said inside diameter and releases the termination tool blade from said bore.
