Pin removal and placement tool

A pin removal and placement tool consistently essentially of:

• a body member defining a contact edge;
• a drive shaft extending from the body member, the drive shaft having a longitudinal axis and a distal end which terminates at a tip, the drive shaft extending from the body member in generally parallel relation to the contact edge with the contact edge extending beyond the tip of the drive shaft;
• an anvil plate on the body member, the anvil plate defining a sole striking surface of the tool and having a striking axis perpendicular to the sole striking surface, the striking axis intersecting the longitudinal axis of the drive shaft at an acute angle θ, the striking surface facing away from the tip of the drive shaft whereby a blow struck against the striking surface will urge the drive shaft in the direction the tip is facing;
• and
• a handle on the body member, the handle extending transversely from a plane defined by the longitudinal axis of the drive shaft and the striking axis of the anvil plate.

A pin removal and placement tool comprising:

• a body member;
• a drive shaft extending from the body member, the drive shaft having a longitudinal axis and a distal end which terminates at a tip;
• a striking surface on the body member, the striking surface having a striking axis perpendicular thereto that intersects the longitudinal axis of the drive shaft at an acute angle θ, the striking surface facing away from the tip of the drive shaft whereby a blow struck against the striking surface will advance the drive shaft in the direction the tip is facing;
• a handle on the body member, the handle extending transversely from a plane defined by the longitudinal axis of the drive shaft and the striking axis of the striking surface;
• and
• an adaptor sleeve that is dimensioned and configured to be slidably mounted on the drive shaft to extend beyond the drive shaft, and to receive a retaining pin therein.

A pin removal and placement tool comprising:

• a body member:
• a drive shaft extending from the body member, the drive shaft having a longitudinal axis and a distal end which terminates at a tip, and the body member defining a contact surface that extends in a generally parallel relation to the longitudinal axis of the drive shaft;
• a sole striking surface on the body member, the striking surface having a striking axis perpendicular thereto that intersects the longitudinal axis of the drive shaft at an acute angle θ, the striking surface facing away from the tip of the drive shaft whereby a blow struck against the sole striking surface will advance the drive shaft in the direction the tip is facing;
• a handle on the body member, the handle extending transversely from a plane defined by the longitudinal axis of the drive shaft and the striking axis of the striking surface;
• and
• the tool further comprising a shoe mounted thereon and comprising a shim plate positioned between the contact surface and the drive shaft.

A method of removing a retaining pin from a first object and a second object, the first object and the second object having aligned holes through which the retaining pin extends to secure the objects together, by utilizing a tool comprising a drive shaft extending from a body member, the drive shaft having a longitudinal axis and a distal end which terminates at a tip, the body member defining a contact surface that extends in a generally parallel relation to the longitudinal axis of the drive shaft to define an offset distance between the contact surface and the drive shaft, a striking surface on the body member, the striking surface having a striking axis perpendicular thereto that intersects the longitudinal axis of the drive shaft at an acute angle θ, the striking surface facing away from the tip of the drive shaft whereby a blow struck against the striking surface will urge the drive shaft in the direction the tip is facing, a handle on the body member, the handle extending transversely from a plane defined by the longitudinal axis of the drive shaft and the striking axis of the striking surface, the method comprising the steps of:

• positioning a shim plate between the contact surface and the drive shaft to adjust the offset distance between the contact surface and the drive shaft;
• gripping the handle of the tool with one hand of the user;
• aligning the tip of the drive shaft of the tool with one end of the retaining pin;
• and
• striking the striking surface with a hammer held in the other hand of the user one or more times as required to drive the retaining pin from the aligned holes sufficiently to separate the two objects.

A method of installing a retaining pin into aligned holes of a first object and a second object in order to secure the objects together by the pin, by utilizing a tool comprising a drive shaft extending from a body member, the drive shaft having a longitudinal axis and a distal end which terminates at a tip, the distal end of the drive shaft being dimensioned and configured to receive and retain an adapter sleeve over the drive shaft, a striking surface on the body member, the striking surface having a striking axis perpendicular thereto that intersects the longitudinal axis of the drive shaft at an acute angle θ, the striking surface facing away from the tip of the drive shaft whereby a blow struck against the striking surface will urge the drive shaft in the direction the tip is facing, a handle on the body member, the handle extending transversely from a plane defined by the longitudinal axis of the drive shaft and the striking axis of the striking surface, the method comprising the steps of:

• placing one end of the adaptor sleeve over the drive shaft and placing one end of the retaining pin in the other end of the adaptor sleeve;
• partially inserting the retaining pin into the aligned holes, leaving a portion of the retaining pin protruding from the aligned holes;
• gripping the handle of the tool with one hand of the user;
• aligning the tip of the drive shaft of the tool with the protruding end of the retaining pin;
• and
• striking the anvil plate with a hammer held in the other hand of the user one or more times as required to drive the retaining pin into the aligned holes sufficiently to secure the two objects together.
