- 16. The apparatus of claim 14, further comprising first and second set screws to couple the tool to the tool adaptor, the first and second set screws to be received in slots of the adaptor device to carry torque from the rotary machine to the tool.
- 17. The apparatus of claim 15, further comprising a groove within the tapered portion of the adaptor body to receive at least one locking member of the adaptor device.
- 18. An apparatus comprising:
a body having a first end and a second end to be coupled to a collet for a rotary machine, the first end having an opening to receive a tool; and a spring constrained within the body to spring lock the tool.
- 19. The apparatus of claim 18, wherein the body has a first threaded portion for coupling to the collet and a second threaded portion for receiving the spring.
- 20. The apparatus of claim 18, wherein the spring is tapered.
- 21. The apparatus of claim 18, wherein the rotary machine comprises a router.
- 22. An apparatus comprising:
a body having a first end and a second end to be coupled to an output shaft of a rotary machine; a spring coupled to the first end of the body; and a cap mounted around the spring and tensioned thereby, the cap fitted in movable relation to the body, the cap having an opening to receive a tool.
- 23. The apparatus of claim 22, wherein the tool is inserted in a first rotational direction and removed in a second rotational direction.
- 24. The apparatus of claim 22, wherein the body comprises a collet nut screwed onto the output shaft.
- 25. The apparatus of claim 22, wherein the spring is threaded onto a mating thread on the first end of the body.
- 26. The apparatus of claim 25, wherein a portion of the spring extends above the first end of the body.
- 27. The apparatus of claim 22, wherein the cap is axially constrained via a groove in the body.
- 28. The apparatus of claim 22, wherein the spring is axially tensioned when the tool is inserted and axially relaxed when the tool is removed.
- 29. The apparatus of claim 22, wherein the spring includes a tang to fit within a groove within the cap.
- 30. An apparatus comprising:
an adaptor body having a first end and a second end, the first end to be coupled to a rotary machine; an actuating collar coupled in movable relation to the adapter body; and a tool adaptor to be coupled to a tool, the tool adaptor dimensioned to be fitted within the second end of the adaptor body.
- 31. The apparatus of claim 30, wherein the actuating collar is movable in a first direction to receive the tool in locking relation, and movable in a second direction to release the tool from the locking relation.
- 32. The apparatus of claim 30, further comprising a plurality of cam members to couple the actuating collar to the adaptor body.
- 33. The apparatus of claim 30, further comprising a plurality of force compensation ring members to lock the actuating collar.
- 34. The apparatus of claim 30, further comprising an inertial lock in the actuating collar.
