Abstract

A removable chuck has a chuck member for holding a drill bit. Also, a mechanism is coupled with the chuck body to retain the chuck body to a drill spindle. The retention mechanism, in a first position, retains the chuck on the drill spindle and in a second position the release mechanism enables the chuck to be removed from the spindle.

Claims

1. A removable chuck comprising:

a sleeve for connecting with a rotating spindle;

a chuck coupled with said sleeve;

a locking mechanism coupled with said sleeve for retaining said sleeve on the rotating spindle, said locking mechanism comprising a locking member for seating in a recess in the spindle, a first biasing member for holding said locking member in the recess, said biasing member movable from a first position, applying a force on said locking member for holding the locking member in the spindle recess, to a second position, where said locking member is out of the spindle recess applying a force on said biasing member;

a locking sleeve surrounding said biasing member, said locking sleeve in a first position prohibiting expansion of the biasing member and removal of said locking member from the spindle recess and said locking sleeve in a second position enabling said sleeve to be removed from the spindle.

2. The removable chuck according to claim 1, further comprising a mechanism for maintaining said locking sleeve in said second position enabling said sleeve to be readily replaced on the spindle.

3. The removable chuck according to claim 2, wherein said maintaining mechanism comprising a biasing member, at least one pin coupled with said biasing member and said pin in an aperture in the sleeve for contact with the spindle, and a latch coupled with the locking sleeve wherein in the locking sleeve first position said pin is on the spindle and in said locking sleeve second position, said pin moving further in said opening in turn latching said biasing member with said latch for maintaining said locking sleeve in said second position and upon replacing said sleeve on the spindle, said pin returning said biasing member from said latch enabling said locking sleeve to return to said first position.

4. The removable chuck according to claim 3, wherein a second biasing member is coupled with said locking sleeve for returning said locking sleeve from said second to first position.

5. The removable chuck according to claim 1, wherein said first biasing member is a spring ring.

9. The removable chuck according to claim 4, wherein a second biasing member is coupled with said locking sleeve for returning said locking sleeve from said second to first position.

10. The removable chuck according to claim 1, wherein said first biasing member is a spring ring.

6. A hand tool comprising:

a hand tool having a rotatable spindle, said spindle including a recess; and

a removable chuck, said removable chuck comprising;

a sleeve coupled with said rotating spindle;

a chuck body coupled with said sleeve;

a locking mechanism coupled with said sleeve for retaining said sleeve on the rotating spindle, said locking mechanism comprising a locking member for seating in a recess in the spindle, a first biasing member for holding said locking member in the recess, said biasing member movable from a first position, applying a force on said locking member for holding the locking member in the spindle recess, to a second position, where said locking member is out of the spindle recess applying a force on said biasing member;

a locking sleeve surrounding said biasing member, said locking sleeve in a first position prohibiting expansion of the biasing member and removal of said locking member from the spindle recess and said locking sleeve in a second position enabling said sleeve to be removed from the spindle.

7. The removable chuck according to claim 6, further comprising a mechanism for maintaining said locking sleeve in said second position enabling said sleeve to be readily replaced on the spindle.

8. The removable chuck according to claim 7, wherein said maintaining mechanism comprising a biasing member, at least one pin coupled with said biasing member and said pin in an aperture in the sleeve for contact with the spindle, and a latch coupled with the locking sleeve wherein in the locking sleeve first position said pin is on the spindle and in said locking sleeve second position, said pin moving further in said opening in turn latching said biasing member with said latch for maintaining said locking sleeve in said second position and upon replacing said sleeve on the spindle, said pin returning said biasing member from said latch enabling said locking sleeve to return to said first position.

11. The hand tool according to claim 6, wherein said spindle includes an aperture for receiving a tool bit.

12. The hand tool according to claim 11, wherein said spindle includes a locking member for retaining said tool bit in said spindle.

13. A removable chuck comprising:

a chuck member, a retention member projecting from said chuck; and

a release member for coupling with a spindle, said release member including a member for automatically locking said retention member upon insertion of said retention member within said release member.

14. The removable chuck according to claim 13, wherein said retention member being a stud projecting from a rear surface of the chuck.

15. The removable chuck according to claim 14, wherein said locking member having an opening for retaining said stud.

16. The removable chuck according to claim 15, wherein said locking member including a flange coupling with said stud.

17. The removable chuck according to claim 16, wherein said release member is rotatable between a first and second position for releasing said stud from said locking member.

18. The removable chuck according to claim 13, wherein said release member including a cut-out for receiving a locking member in the spindle for retaining a tool bit in the spindle.

19. A hand tool comprising:

a hand tool having a rotatable spindle; and

a removable chuck comprising;

a chuck body with a retention member projecting from said chuck body; and

a release member coupled with said spindle, said release member including a member for automatically locking said retention member upon insertion of said retention member within said release member.

20. The removable chuck according to claim 19, wherein said retention member being a stud projecting from a rear surface of the chuck body.

21. The removable chuck according to claim 20, wherein said locking member having an opening for retaining said stud.

22. The removable chuck according to claim 21, wherein said locking member including a flange coupling with said stud.

23. The removable chuck according to claim 22, wherein said release member is rotatable between a first and second position for releasing said stud from said locking member.

24. The removable chuck according to claim 19, wherein said release member including a cut-out for receiving a locking member in the spindle for retaining a tool bit in the spindle.
