MACHINERY used in glass working is certainly susceptible of great improvement, although it is far enough in advance of that in use a few years ago. But of patents granted for “improvements,” perhaps one in twenty is adopted and proves a success. He lately patented device for the improvement of glass presses is worthy of mention. It is the invention of J. C. Gill, a practical mold maker of this city, and consists of a new way of attaching the plunger to the piston. A taper nut on the piston, in connection with pivoted jaws adapted to fit into small grooves in the head of the plunger, attaches the latter to the piston as solidly and securely as if the two were cast in one piece. The attachment can be made in a minute or two, instead of the half hour required to adjust the parts by the old method. The wearing of bolts and screw holes is entirely obviated, and the occasional breaking of a bolt and necessary drilling out done away with. Mr. Gill's device is now in use and Doyle and Co.'s, McKee and Bros., and Adams and Co.'s factories, and is to be applied to presses and those of Hobbs, Bruckunier and Co., of Wheeling, the LaBelle Glass Co., and a new one at Wellsburg W. Va.
