A method for disassembly includes the steps of unfastening the base member, gaining access to the internal fasteners, unfastening them, and pulling out the tap spindle member.
Claims29
A self-reversing tapping attachment comprising:
- (a) tap spindle means for holding a tap and rotatable for accomplishing tapping;
- (b) forward drive means engageable with said tap spindle means to impart rotation to said tap spindle means for accomplishing tapping;
- (c) reverse drive means engageable with said tap spindle means to impart rotation to said tap spindle means in an opposite direction to rotation imparted by said forward drive means;
- (d) gear means for transmitting drive to said forward drive means and said reverse drive means, said tap spindle means being moveable back and forth along the direction of tapping relative to said forward drive means and said reverse drive means;
- and
- (e) dampener means engageable with at least one of said forward drive means and said reverse drive means.
A self-reversing tapping attachment comprising:
- (a) a housings;
- (b) gear means contained within said housing and connectable to a source of rotational power;
- (c) a forward drive member contained within said housing and engageable with said gear means;
- (d) a reverse drive member contained within said housing and engageable with said gear means;
- (e) a tap holding spindle member within said housing movable relatively to said forward member and said reverse drive member to be engageable therewith;
- (f) first securement means detachably mountable on said housing;
- and second securement means detachably mountable in said housings for holding and containing said forward drive member, said reverse drive member, gear means, and said tap holding spindle member within said housings such that upon detachment of said first removable securement means and said second securement means, said gear means, said forward drive member, said reverse drive member, and said tap holding spindle member are removable from said housing.
A method for disassembling a tapping attachment having a housing with a detachable base member and internal fastener means for retaining a tap holding spindle member comprising the steps of:
- (a) loosening said base member;
- (b) unfastening said internal fastener means;
- (c) removing said base member;
- (d) pulling said tap holding spindle from said housings.
