Claim 7

An adapter according to claim 4; wherein said support is a hollow cylinder and the drill speeder housing is secured in the bore of said cylinder.

Claim 8

An adapter according to claim 5; wherein the drill speeder housing is received within the forward portion of the bore of said hollow cylinder, and said coupling member is journalled in the rearward portion of the bore of said hollow cylinder.

Claim 9

An adapter according to claim 4; wherein said securing means comprises a key engageable with a keyway in the frame of the machine tool for securing said support and its associated drill speeder housing against rotation as the drill speeder is being actuated by the machine tool spindle.

Claim 10

An adapter according to claim 4; including locking means actuatable to lock said coupling member against rotation relative to said support; and, releasing means for disengaging said locking means when said coupling member is inserted into the machine tool spindle to release said coupling member for rotation relative to said support.

Claim 11

An adapter according to claim 8; wherein said locking means comprises a key slidably carried by said support and slidable into a keyway formed in said coupling member for locking said coupling member against rotation relative to said support.

Claim 12

An adapter according to claim 9; a spring mounted in said support to continuously urge said slidable key into engagement with its cooperating keyway in said coupling member for preventing relative rotation; an arm attached to said slidable key in position to engage the frame of the machine tool when said coupling member is being inserted into the machine tool spindle and to move said key against the pressure of said spring out of its cooperating keyway when said coupling member is fully inserted into the spindle to release said coupling member for rotation relative to said support.

Claim 13

In a drill driver for actuation by a rotary machine tool spindle which is supported by the frame of the machine tool, said drill driver having a housing enclosing a drive mechanism which may be actuated to rotate a drill carrying spindle for rotating the drill; a coupling member rotatable relative to said drill driver housing and adapted to be inserted into the machine tool spindle for transmitting the rotary drive from the machine tool spindle to said drill drive mechanism for rotating the drill; means on said drill drive housing that moves into engagement with cooperating means on the frame of the machine tool when said coupling member is inserted into the machine tool spindle to fix said housing against rotation while said coupling member is being rotated by the machine tool spindle; locking means in engagement with said housing and said coupling member to fix said coupling member against rotation relative to said housing when the drill driver is removed from the machine tool spindle; and release means actuated by the insertion of said coupling member into the machine tool spindle to release said locking means so that said coupling member can be rotated relative to said housing.

Claim 14

In a drill driver for actuation by a rotary machine tool spindle which is supported by the frame of the machine tool, said drill driver having a housing enclosing a drive mechanism which may be actuated to rotate a drill carrying spindle for rotating the drill; a coupling member rotatable relative to said drill driver housing and adapted to be inserted into the machine tool spindle for transmitting the rotary drive from the machine tool spindle to said drill drive mechanism for rotating the drill; means on said drill drive housing that moves into engagement with cooperating means on the frame of the machine tool when said coupling member is inserted into the machine tool spindle to fix said housing against rotation while said coupling member is being rotated by the machine tool spindle; locking means in engagement with said housing and said coupling member to fix said coupling member against rotation relative to said housing when the drill driver is removed from the machine tool spindle; and release means actuated by the insertion of said coupling member into the machine tool spindle to release said locking means so that said coupling member can be rotated relative to said housing.

Claim 15
