US Patent:

40824756, Apr 4, 1978

Filed:

Mar 9, 1977

Appl. No.:

5/776089

Inventors:

Alfred W. Kuder - Placentia CA

International Classification:

B23B 4704

US Classification:

408125

Abstract:

There is disclosed an attachment for a counter-rotating coaxial drive fastener gun having a cylindrical housing adapted to be threadably attached to the outer drive member of a coaxial drive fastener gun and having an inner cavity with a ring gear fixedly attached therein. A spider has a projecting end thereon adapted to engage the inner drive of the coaxial drive fastener gun and further has a plurality of planetary gears journaled therearound and is inserted into the inner cavity of the cylindrical housing with the planetary gears engaging the ring gear. A central drive gear of smaller diameter than the planetary gears is inserted into a central opening between the planetary gears and engages each of the planetary gears. A reamer is removably coupled to the central drive gear and rotated thereby. A locking mechanism is attached to the coaxial drive fastener gun to prevent the outer drive member from rotating and allowing the inner drive member to rotate and turn the spider at the speed of rotation of the fastener gun which, in turn, rotates the central drive gear and reamer at a faster speed of rotation.

Abstract:

There is disclosed a universal or swivel joint having a ball member with an axis of rotation and a projection of substantially spherical shape centered on the axis, the surface of the projection containing a plurality of facets aligned with and uniformly and symmetrically positioned angularly around the axis of rotation, and a socket member having an axis of rotation and a receptacle centered on the axis which receptacle receives and mates with the ball member, the receptacle having an interior surface containing a plurality of facets aligned with and uniformly and symmetrically positioned angularly around the axis of rotation of the socket member, each of the facets of the receptacle mating with and being positioned in sliding engagement with a respective facet of the ball member. The universal ball and socket swivel joint may have a central opening therethrough symmetrically positioned about the axis of rotation of the ball member and the socket member into which another smaller ball and socket assembly substantially similar thereto may be coaxially aligned and located therein to form a dual independent coaxial universal swivel joint which may be connected to a coaxial drive fastener gun for driving a torque shear-bolt and nut assembly to angularly displace the coaxial drive axis of the fastener gun from the axis of rotation of the torque shear-bolt and nut.
