Glass Novelties at Perfection; patent threading device may be used on insulators

GLASS NOVELTIES AT THE PERFECTION.

The Perfection Glass Mfg. Co., Washington, Pa., have a new fruit jar which has a glass cap, but no metal is used in its construction. There is only a rubber band to help seal the glass screw cap. A new form of molds for pressing the cap has been devised, so that it can be produced almost as rapidly as a cap without the screw thread. A ratchet arrangement is attached to the mold for withdrawing the screw as soon as the cap is pressed. Patent has been applied for and the device may also be used on an insulator mold or for making any glass article requiring a thread.

A shaker salt with a glass top and glass salt stirrer is another novelty produced at the above mentioned plant which requires a specially designed designed mold. An all-glass separated decanter with screw and requiring no metal fitting, and also a pressed round holophane globe are other articles lately brought out. The company expect to erect a continuous tank this summer at which several shops will be employed, producing the new glass top jar for which some excellent orders have already been booked.
