Stapler

In 1868, a stapler was patented in Birmingham, England by C.H. Gould (No. 765; provisional protection only). An abridgment of the specification for the stapling tool, published by the Patent Office (1904), described it as: “Through a short handle passes a rectangular metal tube, in which works a punch, the lower end of which guides the staple &c. into the work, a spring at the side of the handle holding the staple in position. The punch projects beyond the handle to the extent of the length of the staple, its top being fashioned as to receive the blow by which the staples are driven, and also to form a stop to prevent them from being overdriven; the blow is modified by a helical spring.”«
