Abstract

The attachment for a stitching tool is an attachment that enables a manually operated stitching tool to convert to a power-operated stitching tool. The attachment includes an ergonomically designed handle mounted on a base, which base is provided with an opening at one end thereof. The opening is designed to receive the grasping portions of a manually operated, conventional stitching tool. Mechanisms in the base engage the grasping portions of the stitching tool to mechanically manipulate the grasping portions. The mechanisms are powered by an electric motor. Controls are provided on the handle for operating the electric motor.

Claims

1. An attachment for a hand tool, comprising:

a base member having a first end and a second end;

a motive power source coupled to the first end of the base member;

an opening disposed in the second end of the base member adapted for receiving a hand tool therein;

an arm member extending from the second end, the arm member having an opening therein;

an ergonomically designed handle mounted on the base member;

a switch mounted on the handle for selectively actuating the power source;

a draw latch disposed on and attached to the handle, a portion of the draw latch extending through the opening in the arm member, the draw latch being adapted for securing the hand tool in the opening and to the arm member; and

means in the base member for actuating the hand tool.

2. The attachment for a hand tool according to claim 1, wherein said means for actuating the hand tool includes a lever mounted for pivotal movement on said base member.

3. The attachment for a hand tool according to claim 2, wherein said power source is a DC motor and further including at least one battery connected to said motor.
