Clamping tool

A hand tool comprising:

• a first jaw;
• a body;
• a second jaw affixedly attached to said body;
• and
• means for mounting said first jaw to said body for linear reciprocal movement with respect to said body, and operative cooperation with said second jaw;
• said mounting means including first means for adjusting the position of said first jaw with respect to said body;
• said first means for adjusting the position of said first jaw with respect to said body comprising:
• an elongated bar attached to said first jaw, and including a linear gear portion thereof, said bar being elongated in a dimension defining the linear path of reciprocation of said first jaw with respect to said body, and said bar being received by said body for linear reciprocation;
• a worm gear rotatable about a pin, said pin operatively mounted by said body, and said pin extending parallel to the dimension of elongation of said bar;
• said worm cooperatively engaging said linear gear of bar;
• and said body providing access to said worm to allow hand adjustment thereof;
• means for mounting said pin for linear reciprocation with respect to said body in a linear path along the axis of said pin, linear reciprocation of said pin effecting linear reciprocation of said gear and thereby linear movement of said first jaw with respect to said body, comprising an elongated slot formed in said body, and a first abutment member extending outwardly from said pin and operatively engaging said slot;
• and a second abutment member for guiding reciprocation of said pin at an end thereof opposite said abutment member.

A hand tool comprising:

• a first jaw;
• a body;
• a second jaw affixedly attached to said body;
• means for mounting said first jaw to said body for linear reciprocal movement with respect to said body, and operative cooperation with said second jaw;
• said mounting means including first means for adjusting the position of said first jaw with respect to said body;
• said first means for adjusting the position of said first jaw with respect to said body comprising:
• an elongated bar attached to said first jaw, and including a linear gear portion thereof, said bar being elongated in a dimension defining the linear path of reciprocation of said first jaw with respect to said body, and said bar being received by said body for linear reciprocation;
• a worm gear rotatable about a pin, said pin operatively mounted by said body, and said pin extending parallel to the dimension of elongation of said bar;
• said worm cooperatively engaging said linear gear of said bar;
• and said body providing access to said worm to allow hand adjustment thereof;
• an extension bar having a linear gear;
• and
• means for operatively connecting said extension bar to said elongated bar to extend the length thereof, and thereby effectively extend the amount said first jaw can be linearly reciprocated with respect to said body.

A hand tool comprising:

• a first jaw;
• a body;
• a second jaw affixedly attached to said body;
• and
• means for mounting said first jaw to said body for linear reciprocal movement with respect to said body, and operative cooperation with said second jaw;
• said mounting means including first means for adjusting the position of said first jaw with respect to said body;
• and second means, including components distinct from said first means, for adjusting the position of said first jaw with respect to said body;
• said second means comprising:
• a hand engageable lever;
• first and second levers, said first lever being pivotally connected at one end thereof to said body, and pivotally connected at another portion thereof to said second lever, and said second lever being operatively pivotally connected at another portion thereof to said first jaw;
• said hand engageable lever connected to said first and second levers at the pivotal connection between said first and second levers so that movement of said hand engageable lever effects movement of said first and second levers between a substantially in-line position, and an angled position, to thereby effect relative movement of said first jaw with respect to said body.
