Claim 2

Apparatus to join a part of the type having a threaded shaft protruding therefrom with a second part of the type having a bore therein and a cavity intersecting said bore, said apparatus comprising: (a) a nut having external circumferential gear surface means; (b) a housing for reception in a cavity of a part of the type having a bore therein and a cavity intersecting said bore, said housing rotatably receiving said nut and having two nut actuator tool bores each of said two nut actuator tool bores terminating in an abutment and communicating at its side with the interior of said housing with said circumferential gear surface of said nut protruding into said side, said two nut actuator tool bores communicating with the interior of said housing at diametrically opposite sides of said nut and sized to permit insertion of a nut actuator tool for rotating said nut, whereby said nut actuator tool may be inserted in one of said two nut actuator tool bores for rotating said nut in one direction and may be inserted in the other of said two nut actuator tool bores for rotating said nut in the opposite direction, said housing having openings to permit a threaded shaft protruding from a part to be threaded through said nut.

Claim 3

The joining apparatus of claim 1 further including: (c) a nut actuator tool for insertion in said two nut actuator tool bores for engaging said gear surface of said nut and for abutting said abutment in order to rotate said nut.

Claim 4

The joining apparatus of claim 1 wherein said housing includes tangs for retaining said nut in said housing.

Claim 5

The joining apparatus of claim 2 wherein said circumferential gear surface of said nut comprises teeth obliquely angled with respect to the ends of the nut to form a worm wheel.

Claim 6

Apparatus to join two parts, comprising: (a) a nut having circumferentially extending external teeth obliquely angled with respect to the ends of the nut to form a worm wheel; (b) a housing receiving said nut, said housing having two nut actuator tool bores, said housing for reception by a part to be joined; (c) a shaft threaded at either end for threading into a second part to be joined and for threading into said nut after reception of said housing by said part; and (d) a nut actuator tool for reception in one of said two nut actuator tool bores to engage said external teeth of said nut in order to rotate said nut in a first direction in order to thread said shaft into said nut and for reception in the other of said two nut actuator tool bores to engage said external teeth of said nut in order to rotate said nut in a second direction in order to expel said shaft from said nut.

Claim 7

Apparatus to join two parts, comprising: (a) a nut having circumferentially extending external teeth obliquely angled with respect to the ends of the nut to form a worm wheel; (b) a housing receiving said nut, said housing having two nut actuator tool bores, said housing for reception by a part to be joined; (c) a shaft threaded at either end for threading into a second part to be joined and for threading into said nut after reception of said housing by said part; and (d) a nut actuator tool for reception in one of said two nut actuator tool bores to engage said external teeth of said nut in order to rotate said nut in a first direction in order to thread said shaft into said nut and for reception in the other of said two nut actuator tool bores to engage said external teeth of said nut in order to rotate said nut in a second direction in order to expel said shaft from said nut.

Claim 8

Apparatus to join a first part of the type having a threaded shaft protruding therefrom with a second part of the type having a bore therein and a cavity intersecting said bore, said apparatus comprising: (a) a nut having external circumferential gear surface means; (b) a housing for reception in a cavity of a part of the type having a bore therein and a cavity intersecting said bore with the bottom of said housing supported by the bottom of said cavity, said housing rotatably receiving said nut and having two nut actuator tool bores each of said two nut actuator tool bores terminating in an abutment and communicating at its side with the interior of said housing with said circumferential gear surface means of said nut protruding into said side, said two nut actuator tool bores communicating with the interior of said housing at diametrically opposite sides of said nut and sized to permit insertion of a nut actuator tool for rotating said nut, whereby said nut actuator tool may be inserted in one of said two nut actuator tool bores for rotating said nut in one direction and may be inserted in the other of said two nut actuator tool bores for rotating said nut in the opposite direction, said housing having openings coaxial with said nut and sized to permit a threaded shaft protruding from a part to be threaded through said nut, said openings located so that the distance between the bottom of said housing and said openings is substantially the same as the distance between the bottom of said cavity and said bore.

Claim 9

Apparatus to join a first part of the type having a threaded shaft protruding therefrom with a second part of the type having a bore therein and a cavity intersecting said bore, said apparatus comprising: (a) a nut having external circumferential gear surface means; (b) a housing for reception in a cavity of a part of the type having a bore therein and a cavity intersecting said bore with the bottom of said housing supported by the bottom of said cavity, said housing rotatably receiving said nut and having two nut actuator tool bores each of said two nut actuator tool bores terminating in an abutment and communicating at its side with the interior of said housing with said circumferential gear surface means of said nut protruding into said side, said two nut actuator tool bores communicating with the interior of said housing at diametrically opposite sides of said nut and sized to permit insertion of a nut actuator tool for rotating said nut, whereby said nut actuator tool may be inserted in one of said two nut actuator tool bores for rotating said nut in one direction and may be inserted in the other of said two nut actuator tool bores for rotating said nut in the opposite direction, said housing having openings coaxial with said nut and sized to permit a threaded shaft protruding from a part to be threaded through said nut, said openings located so that the distance between the bottom of said housing and said openings is substantially the same as the distance between the bottom of said cavity and said bore.

Claim 10

The apparatus of claim 6 wherein said external circumferential gear surface means comprises a bevel gear surface at either end of said nut, each said bevel gear surface protruding into the side of one of said two nut actuator tool bores.

Claim 11

The joining apparatus of claim 7 wherein said housing includes tangs for retaining said nut in said housing.

Claim 12

The joining apparatus of claim 8 further including: (c) a nut actuator tool for insertion in said at least one nut actuator tool bore for engaging said gear surface of said nut and for abutting said abutment in order to rotate said nut.
