Abstract

Abstract An upsetting Rivnut or Plusnut tool having a stationary held body member with a smooth bore extending therethrough and receiving an elongated longitudinal movable member. The elongated member has its opposite ends threaded with one end adapted to receive the Plusnut or Rivnut for upsetting while the other threaded end receives a nut for rotation relative to the stationary held body member. Interlocking means interconnect the body member and the elongated member to assure non-rotation axial movement of the elongated member and the shank of the Plusnut for the upsetting action.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 189 words
A hand powered upsetting tool for outwardly expandinG the shank of an internally threaded tubular Rivnut or Plusnut comprising a body, said body having a longitudinally extending smooth walled bore throughout the length thereof, said body having a polygonal outer surface for receiving a wrench, said bore being reduced in cross section at one end of said body, the juncture of said reduced bore with said main through bore presenting an annular abutment, an elongated member journaled in said bore of said body, said elongated member having an upper threaded portion and a lower reduced threaded stem portion, the juncture of said upper threaded portion and lower reduced stem portion provides a shoulder for engagement by said annular abutment, a nut threadedly mounted on said upper threaded portion for exerting axial pressure on said body, said body having slot means for communicating said smooth walled bore with the said outer surface thereof, and said elongated member having a pin extending transversely therethrough and projecting into said slot means of said body for interconnecting said body and said elongated member to prevent relative rotation therebetween but permit longitudinally movement therebetween.
Claim 2
Dependent Claim 189 words
A hand powered upsetting tool for outwardly expandinG the shank of an internally threaded tubular Rivnut or Plusnut comprising a body, said body having a longitudinally extending smooth walled bore throughout the length thereof, said body having a polygonal outer surface for receiving a wrench, said bore being reduced in cross section at one end of said body, the juncture of said reduced bore with said main through bore presenting an annular abutment, an elongated member journaled in said bore of said body, said elongated member having an upper threaded portion and a lower reduced threaded stem portion, the juncture of said upper threaded portion and lower reduced stem portion provides a shoulder for engagement by said annular abutment, a nut threadedly mounted on said upper threaded portion for exerting axial pressure on said body, said body having slot means for communicating said smooth walled bore with the said outer surface thereof, and said elongated member having a pin extending transversely therethrough and projecting into said slot means of said body for interconnecting said body and said elongated member to prevent relative rotation therebetween but permit longitudinally movement therebetween.
Claim 3
Dependent Claim 27 words
A hand powered upsetting tool as set forth in claim 1 wherein a bearing member is journaled on said elongated member between said nut and said body.
Claim 4
Dependent Claim 230 words
A hand powered upsetting tool for flanging the shank of an internally threaded tubular Plusnut comprising a body; said body having an outer longitudinally extending outer surface and a longitudinally extending smooth walled bore therethrough; said outer surface of said body having at least a pair of spaced flat surfaces for engagement by a tool; said bore being reduced in cross section at the one end of said body; a slot in said outer surface of said body communicating the outer surface with said bore; said body having a flat annular surface on the lower end portion for bearing against the flange of a Plusnut; said body having elongated slot means communicating said outer surface of said body with said bore; an elongated member journaled in said bore of said body; the upper end portion of said elongated member being threaded; the lower end portion of said elongated member being reduced in cross section providing a stem portion; the terminal end portion of said stem portion being threaded; a nut threadedly mounted on said upper threaded portion for rotation relative to said elongated member; a washer journaled on said upper threaded portion between said nut and said body; and interlocking means interconnecting said elongated member to said body by projecting into said slot means to prevent relative rotation between said body and said elongated member but permit longitudinally movement therebetween.
Claim 5
Dependent Claim 230 words
A hand powered upsetting tool for flanging the shank of an internally threaded tubular Plusnut comprising a body; said body having an outer longitudinally extending outer surface and a longitudinally extending smooth walled bore therethrough; said outer surface of said body having at least a pair of spaced flat surfaces for engagement by a tool; said bore being reduced in cross section at the one end of said body; a slot in said outer surface of said body communicating the outer surface with said bore; said body having a flat annular surface on the lower end portion for bearing against the flange of a Plusnut; said body having elongated slot means communicating said outer surface of said body with said bore; an elongated member journaled in said bore of said body; the upper end portion of said elongated member being threaded; the lower end portion of said elongated member being reduced in cross section providing a stem portion; the terminal end portion of said stem portion being threaded; a nut threadedly mounted on said upper threaded portion for rotation relative to said elongated member; a washer journaled on said upper threaded portion between said nut and said body; and interlocking means interconnecting said elongated member to said body by projecting into said slot means to prevent relative rotation between said body and said elongated member but permit longitudinally movement therebetween.
