Abstract

A plurality of roll pin punches in association with an elongate handle are mounted for ease of assembly within a container structure. A cap member having an internally threaded bore and including a forward wall bore coaxially aligned through the forward wall and the threaded bore includes a resilient "O" ring mounted within a toroidal groove and interfaced between the threaded bore and the forward wall bore to secure the punch member.

Claims2

Dependent claims

A roll pin punch kit apparatus, comprising,

an elongate cylindrical handle, the cylindrical handle having a predetermined handle diameter,
and
the handle including a handle forward wall,
and
an externally threaded shank coaxially aligned relative to the cylindrical handle and extending from and beyond the handle forward wall,
and
a plurality of punch members, each punch member including a punch shank defined by a shank diameter received through the externally threaded shank within the handle,
and
a cap member threadedly receiving the externally threaded shank therewithin for securement of the punch shank within the handle,
and
the externally threaded shank includes a shank bore directed coextensively through the externally threaded shank and extending into the handle coaxially aligned with the externally threaded shank and the handle, with the externally threaded shank bore defined by said shank diameter to complementarily receive the punch shank therewithin,
and
the cap member includes a cap member forward wall, the cap member forward wall including a cylindrical forward wall bore defined by a forward wall bore diameter substantially equal to the shank diameter, and an internally threaded counter bore coaxially aligned and intersecting the forward wall bore extending from the forward wall bore coextensively through the cap member, and a toroidal groove defined by a groove diameter greater than the shank diameter at an interface between the forward wall bore and the internally threaded counter bore, wherein the internally threaded counter bore, the forward wall bore, and the toroidal groove are coaxially aligned relative to the cap member, and a resilient "O" ring received within the toroidal groove,
and
each punch member includes a punch member cylindrical projection extending coaxially of and forwardly of the punch shank, and a tubular alignment sleeve arranged for complementarily receiving the cylindrical projection therethrough for alignment of the cylindrical projection relative to a workpiece,
and
the alignment sleeve includes a sleeve bore coextensively directed through the alignment sleeve equal to a predetermined length and a bore diameter to complementarily receive the cylindrical projection therewithin, and the alignment sleeve including a sleeve rear wall, the sleeve rear wall having a plurality of leg members mounted to the sleeve rear wall extending in a parallel spaced relationship to the alignment sleeve, wherein the leg members are defined by a leg length greater than the predetermined length of the sleeve bore,
and
each leg member includes a plurality of segments, the segments are arranged for threaded inter-engagement relative to one another in a coaxially aligned relationship.
