The court below having granted a preliminary injunction enjoining patent infringement, defendants appealed. On hearing by this court, it was agreed the case might be disposed of as if on final hearing.
The patent involved was considered by this court in Hartford-Empire Co. v. Hazel-Atlas Glass Co., reported in
Briefly stated, the functional invention of that patent was the swelling of a gob in suspension to desired shape and shearing such shaped gob in suspension. The patentee showed it could be done by the use of what he called an “impeller,” saying: “The various characteristics of the impeller action may be varied”; adding: “As the impeller moves upward it gives an upward or intrusion impulse to the glass within and below the outlet,” and “the downward or extrusion impulse of the impeller may be used to control the shape of the body and upper end of the. gather and its resulting mold charge.” The particular form of impeller the patentee showed was a metallic plunger which discharged or retarded the glass as desired. The present defendant, as its discharge or retard apparatus, uses a double-acting diaphragm, which, actuated by compressed air, will discharge or retard the glass as desired.
It is clear that, if the defendants’ apparatus, with a diaphragm acting to discharge or retard glass in suspension to desired form, and shearing the glass, as it does, in suspension, had been in use before the patent in suit, it would have been a complete anticipa
In the Hartford-Empire-Hazel-Atlas Case, this court held the claims in suit valid and broad enough to cover the alleged infringing device there in question. Differing sharply as to the scope of the claims and, in consequence, differing on the issue of infringement, I dissented. Regarding myself bound by that decision of the court, I concur in the findings of validity and infringement of the claims here in suit.
