ABSTRACT:
Gas burners; particularly, apparatus for punching holes or ports in gas burner tubing. The apparatus includes a base and superposed frame, a press head with punch, which is reciprocally mounted in the upper part of the frame and a rotatably driven eccentric shaft which engages, so as to reciprocate the press head. As the press head reciprocates, the punch engages the receiving end of a gas burner tubing which is supported in a tube collar positioned within the lower part of the frame. The trailing end of the tubing is supported upon a tube arbor which is advanced incrementally towards the tube collar, as the punch is reciprocated. The apparatus is characterized by its capability of rapid punching of a longitudinally aligned series of ports in a gas burner tubing, with precise adjustment of port size and distance between ports.
