Abstract

Abstract A wrench having an elongated handle attached to a head. A spool and rotatable member are rotatably mounted in the head. A one-way clutch drivably connects the spool with rotatable member. A cable wound around the spool extends longitudinally through the passage in the handle. When the cable is pulled out of the handle the spool is rotated. The one-way clutch drives the rotatable member which rotates without swinging the handle. A spring acting on the spool rotates the spool to wind the cable on the spool. A releasable lock interposed between the handle and the spool permits rotation of the spool in resonse to angular movement of the handle.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 290 words
In a wrench for rotating a socket or the like having an elongated handle with an annular head at one end and a longitudinal passage through the handle, said head having a cavity receiving a rotatable drive member having a drive projection, a sleeve in said cavity surrounding said rotatable member, one-way clutch means operable between said member and sleeve, a cable wound around the sleeve and extending outwardly through said handle passage for turning the sleeve and clutched drive member in one direction when pulled outwardly through said passage, and spring means coupled between said head and said sleeve biasing the sleeve to turn declutched in the other direction to rewind the cable around the sleeve, the improvement therein comprising: said drive member having axially spaced radially outwardly extending annular flanges defining therebetween a circumferential groove, said one-way clutch means including an annular series of inclined ramps on said drive member between said flanges, a plurality of inclined ramps on said sleeve in concentric relation to said drive member, and a plurality of rollers disposed between said ramps and lying within and retained by said drive member groove, said head includes an annular inwardly extending flange at one end of said cavity, said sleeve includes an inwardly extending annular flange at one axial end thereof substantially engaging said head flange so as to restrict axial movement of said sleeve theretoward, one of said drive member flanges includes a portion thereof substantially engaging said sleeve flange so as to restrict axial movement of said drive member theretoward, and, means at the other end of said cavity and said sleeve to preclude axial movement of said sleeve and said drive member, respectively, therepast, thereby to maintain said wrench in assembled relation.
Claim 2
Dependent Claim 290 words
In a wrench for rotating a socket or the like having an elongated handle with an annular head at one end and a longitudinal passage through the handle, said head having a cavity receiving a rotatable drive member having a drive projection, a sleeve in said cavity surrounding said rotatable member, one-way clutch means operable between said member and sleeve, a cable wound around the sleeve and extending outwardly through said handle passage for turning the sleeve and clutched drive member in one direction when pulled outwardly through said passage, and spring means coupled between said head and said sleeve biasing the sleeve to turn declutched in the other direction to rewind the cable around the sleeve, the improvement therein comprising: said drive member having axially spaced radially outwardly extending annular flanges defining therebetween a circumferential groove, said one-way clutch means including an annular series of inclined ramps on said drive member between said flanges, a plurality of inclined ramps on said sleeve in concentric relation to said drive member, and a plurality of rollers disposed between said ramps and lying within and retained by said drive member groove, said head includes an annular inwardly extending flange at one end of said cavity, said sleeve includes an inwardly extending annular flange at one axial end thereof substantially engaging said head flange so as to restrict axial movement of said sleeve theretoward, one of said drive member flanges includes a portion thereof substantially engaging said sleeve flange so as to restrict axial movement of said drive member theretoward, and, means at the other end of said cavity and said sleeve to preclude axial movement of said sleeve and said drive member, respectively, therepast, thereby to maintain said wrench in assembled relation.
Claim 3
Dependent Claim 36 words
The improved wrench of claim 1 wherein said last named means comprise a snap ring carried by said sleeve to restrain said drive member and a snap ring carried by said head to restrain said sleeve.
Claim 4
Dependent Claim 23 words
The improved wrench of claim 1 further including cam means for selectively locking said head to said sleeve thereby to disable said clutch.
Claim 5
Dependent Claim 27 words
The improved wrench of claim 3 wherein said cam means is carried by said elongated handle and includes a member projectable from said handle into said cavity.
