Abstract
Abstract A nut socket attachment for a power driven nut fastener. An elongated housing encloses a central drive operably attachable to the output of a powered nut fastener. A wrench socket is rotatably driven by the central drive and includes a hexagonal socket recess in which to collect and retain a received nut. Spring biased to project axially inward of the socket recess, is a peripherally threaded relatively stationary cylindrical nut collecting and retaining member. Rotating the socket initially in a reverse direction draws or collects the received nut onto the retainer inwardly of the socket. Subsequently, rotating the socket in a forward direction forces the collected nut off the retainer outwardly of the socket onto its fastening bolt or stud.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
173 words
A fastener retainer attachment for power tools comprising in combination: a. a rotatable socket spindle having a socket recess for receiving a nut to be retained; b. drive means adapted for drive engaging attachment to the output drive of a power operated fastener tool with which it is to be utilized and operable when driven by said tool output for rotating said spindle; c. a nut retaining member support coaxially of said spindle and having an end portion projecting axially inwardly of said socket recess; d. threads on the periphery of said retainer end portion effective when said spindle is rotated in a first direction to thread a received nut inwardly of said socket recess and effective when said spindle is rotated in an opposite second direction to thread a received nut outwardly of said socket recess; and e. clutch means operable connected to said retaining member for enabling first direction rotation of said retainer concomitantly with said spindle in response to a predetermined inwardly threaded position being reached by the received nut.
Claim 2
Dependent Claim
173 words
A fastener retainer attachment for power tools comprising in combination: a. a rotatable socket spindle having a socket recess for receiving a nut to be retained; b. drive means adapted for drive engaging attachment to the output drive of a power operated fastener tool with which it is to be utilized and operable when driven by said tool output for rotating said spindle; c. a nut retaining member support coaxially of said spindle and having an end portion projecting axially inwardly of said socket recess; d. threads on the periphery of said retainer end portion effective when said spindle is rotated in a first direction to thread a received nut inwardly of said socket recess and effective when said spindle is rotated in an opposite second direction to thread a received nut outwardly of said socket recess; and e. clutch means operable connected to said retaining member for enabling first direction rotation of said retainer concomitantly with said spindle in response to a predetermined inwardly threaded position being reached by the received nut.
Claim 3
Dependent Claim
58 words
A fastener retainer according to claim 1 including spring means biasing said retaining member toward projecting inwardly of said socket recess, said spring means enabling said retaining member to axially recede from said socket recess for accommodating receipt of a fastener end on which a retained nut is being assembled during said second directional rotation of said spindle.
Claim 4
Dependent Claim
21 words
A fastener retainer according to claim 2 including spring means biasing said clutch means toward restraining said retaining member against rotation.
Claim 5
Dependent Claim
29 words
A fastener retainer according to claim 3 in which said clutch means comprise a first jaw secured against rotation and a second jaw rotationally coupled to said retaining member.
Claim 6
Dependent Claim
36 words
A fastener retainer according to claim 4 in which the faces of said jaws have mutually opposite edges adapted to axially overlap and engageable in a rotational direction for effectively restraining said second jaw against rotation.
Claim 7
Dependent Claim
59 words
A fastener retainer according to claim 5 in which said jaw edges are axially biased into overlapping relation by said spring means and include a first pair of mutually opposite edges engageable when said spindle is rotated in said first direction and a second pair of mutually opposite edges engageable when said spindle is rotated in said second direction.
Claim 8
Dependent Claim
50 words
A fastener retainer accordiNg to claim 6 in which said first pair of mutually opposite jaw edges extend at an oblique angle to a plane parallel to the axis of spindle rotation and said second pair of mutually opposite jaw edges extend substantially parallel to the axis of spindle rotation.
Claim 9
Dependent Claim
28 words
A fastener retainer according to claim 7 in which said predetermined inward position reached by the received nut comprises engaging against the bottom wall of said socket recess.
Claim 10
Dependent Claim
75 words
A fastener retainer according to claim 8 in which said second jaw is axially slideable relative to said retaining member and in which bottom wall engagement by the received nut imposes a first direction rotational force against said second jaw sufficient to wedgedly slide said second jaw on said first pair of jaw edges in opposition to said spring means toward said retaining member and away from said first jaw until rotationally past the latter.
Claim 11
Dependent Claim
33 words
A fastener retainer according to claim 9 in which the axis of said spindle extends substantially normal to the rotational output axis of a tool on which it is adapted to be attached.
