Abstract
Automatic nailing machine provided with a magnetic attraction means on the side wall of the guide hole through which a piston rod driven by compressed air passes during the nailing operation. The machine is constructed so the nail to be driven, supplied to the guide hole from a magazine connected to the guide hole to supply nails thereinto, is held temporarily by said magnetic attraction means before the piston rod lowers and drives the nail.
Claims2
In an automatic nail driving device having a guide hole through which the nail to be driven is driven, a reciprocal compressed air piston rod means at the top of said guide hole above said nail for driving said nail downward, and a magazine means at the side of said guide hole for supplying nails to said guide hole, the improvement comprising:
- a magnetic attraction means positioned on the side of said guide hole opposite said magazine at a right angle to said guide hole and resiliently projecting into said guide hole for attracting said nails in said magazine, said attraction means comprised of:
- at least one cylindrical member fitted through the wall of said guide hole opposite said magazine at a right angle to said guide hole and having an opening into said guide hole,
- a spherical permanent magnet in said cylindrical member at the end thereof open into said guide hole, and
- biasing means within said cylindrical member against said permanent magnet for resiliently forcing said magnet toward said guide hole.
