Abstract
Abstract A tool handle assembly including a hand grip to be engaged by one hand, having a freely-reversible socket member carried thereby which has a socket for non-rotatably and removably receiving a tool adapter, the tool adapter having a socket for non-rotatably and removably receiving a tool element, and a finger grip or spinner for engaging by the fingers of the other hand, non-rotatably fixed on the adapter. The socket member is mounted in the hand grip by means of a one-way driving spring clutch. All the parts of the assembly are so arranged that the spinner does not contact the adjacent end of the hand grip so that these members are always free to rotate relatively, to permit free reversal of the hand grip.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
163 words
A handle assembly for receiving and applying torque to a tool element comprising a hand-grip assembly and a tool adapter assembly; said hand grip assembly and a tool adapter assembly being mounted for rotation relative to one another; said hand grip assembly comprising a hand grip body, socket member rotatably mounted in said body and having an outwardly-opening adapter-receiving socket, a spring clutch mounted in said hand grip body in cooperation with said socket member to prevent relative rotation in one direction but permit relative rotation in a reverse direction; said tool adapter assembly having a finger-grip collar non-rotatably mounted thereon and having an inwardly extending shank portion adapted to removably fit in said adapter-receiving socket and an outwardly extending socket portion with an outwardly-opening tool-receiving socket for receiving the shank of a tool element, said adapter shank contacting the adapter-receiving socket member to provide a space between said hand grip body and said collar to permit said relative rotation at all times.
Claim 2
Dependent Claim
163 words
A handle assembly for receiving and applying torque to a tool element comprising a hand-grip assembly and a tool adapter assembly; said hand grip assembly and a tool adapter assembly being mounted for rotation relative to one another; said hand grip assembly comprising a hand grip body, socket member rotatably mounted in said body and having an outwardly-opening adapter-receiving socket, a spring clutch mounted in said hand grip body in cooperation with said socket member to prevent relative rotation in one direction but permit relative rotation in a reverse direction; said tool adapter assembly having a finger-grip collar non-rotatably mounted thereon and having an inwardly extending shank portion adapted to removably fit in said adapter-receiving socket and an outwardly extending socket portion with an outwardly-opening tool-receiving socket for receiving the shank of a tool element, said adapter shank contacting the adapter-receiving socket member to provide a space between said hand grip body and said collar to permit said relative rotation at all times.
Claim 3
Dependent Claim
53 words
A handle assembly according to claim 1 in which the socket member in the hand grip body and the tool adapter shank are axially aligned and have contacting adjacent ends, said hand grip body having an end which is adjacent to said collar but is spaced therefrom by contact of said contacting ends.
Claim 4
Dependent Claim
34 words
A handle assembly according to claim 2 in which the said end of the hand grip body is convex and the collar has an adjacent face with a concave pocket for receiving said end.
Claim 5
Dependent Claim
19 words
A handle assembly according to claim 3 in which the collar has a peripheral surface which is concavely grooved.
Claim 6
Dependent Claim
34 words
A handle assembly according to claim 3 or claim 4 in which both ends of the hand grip body are of the convex form, and an adapter-receiving socket member is mounted in each end.
Claim 7
Dependent Claim
70 words
A handle assembly according to claim 2 in which the adapter-receiving socket member in the hand grip body is driven by a driving member anchored in said body in a socket in the hand grip axially inwardly of said socket member, said members having axially-aligned shaft portions in said last-named socket and said spring clutch comprising a spring wound around said shaft portions and engaging the wall of the socket.
Claim 8
Dependent Claim
19 words
A handle assembly according to claim 6 in which the shaft portions have inner ends in relatively rotatable contact.
Claim 9
Dependent Claim
45 words
A handle assembly according to claim 2 in which each end of the hand grip body has a socket member rotatably mounted therein with a spring clutch which permits rotation of the socket member in a reverse direction relative to that at the other end.
Claim 10
Dependent Claim
45 words
A handle according to claim 6 in which the hand grip has an outwardly-opening socket at each end with the adapter-receiving socket member and driving member along with the cooperating spring mounted therein the springs in the sockets at the opposite ends being reversely wound.
