Attachment for converting a reciprocating power tool into power driven hack saw

A hack saw attachment for converting an electrically driven reciprocating tool assembly into an electrically powered hack saw, said tool assembly including a sole plate having an outer surface, and a power driven arbor for reciprocating a tool through an open slot in said sole plate, said attachment comprising a flat attachment plate having inner and outer faces, a hack saw frame having an inner end centrally fixed to said outer face of said attachment plate and extending away from said attachment plate perpendicularly thereto, said frame having a down-turned outer end, a slotted first guide carried by the inner end of said frame for slidably receiving an inner end of a hack saw blade, means for releasably connecting to said sole plate said flat attachment plate with its inner face in abutment with said sole plate, said first guide being positioned on said frame such that when said flat attachment plate is releasably connected to said sole plate, said first guide aligns with said slot in said sole plate and with said arbor, a second guide carried by said down-turned outer end of said frame in alignment with said first guide, a second arbor reciprocally slidable within said second guide, means for releasably connecting an outer end of the hack saw blade to said second arbor, and a spring acting on said second arbor resiliently urging it in a direction away from said first blade guide at the inner end of said frame.
