Two pile height mending gun

A hand-held mending gun comprising:

• a rotary motor;
• a needle carrier adapted to be driven in reciprocal motion;
• a first drive mechanism coupling the rotary motor to the needle carrier to convert rotary motion of the motor to reciprocation of the needle carrier;
• a needle supported by the needle carrier;
• a circular drive disk rotated by the rotary motor;
• a yarn feed disk in contact with the drive disk and relocatable between two locations relative to a radius of the drive disk;
• a pneumatic cylinder having a piston with a retracted and an extended position operatively coupled to the yarn feed disk to move said yarn drive disk relative to the drive disk thereby to provide a low pile height setting and a high pile height setting as said piston is retracted and extended selectively.

A hand-held mending gun comprising:

• a rotary motor operatively coupled to a drive disk;
• a needle carrier supplied with yarn feed air to direct yarn through the needle;
• a first drive mechanism connecting the rotary motor to the needle carrier converting the rotary motion of the rotary motor into reciprocatory motion of the needle carrier;
• a hollow needle supported by the needle carrier;
• a pneumatic cylinder adapted to receive a control air, said cylinder having a piston moveable from a retracted to an extended position with the receipt of control air;
• a selector valve adapted to receive inlet air and selectively provide control air to the pneumatic cylinder;
• and
• a common air supply providing the yarn feed air and the inlet air.
