Homer Brooke Glass Co. v. Hartford-Fairmont Co., 255 F. 901, 1919 U.S. Dist. LEXIS 972 (D. Conn. 1919).

Opinion

THOMAS, District Judge.

This is the usual hill in equity, alleging that letters patent No. 723,983 were granted to Homer Brooke on the 31st day of March, 1903, upon an application filed March 5, 1898, and charging the defendant with infringement, and praying for an injunction and an accounting. The defenses are invalidity and noninfringement.

The invention, as stated in the specification, relates to—

“devices for cutting or separating molten material, and especially is designed for witting a stream of flowing molten glass into unformed molten -masses of predetermined quantity and distributing the same into suitable receptacles.”

The bill charges infringement of claims 1, 2, 3, 4, 5, 6, 7, and 9, hut at final hearing counsel for plaintiffs withdrew consideration as to claims 1, 2, 6, 7, and 9, and now relies on claims 3, 4, and 5, which are as follows:

“3. An automatic device for cutting or separating a flowing stream of molten material into unformed molten masses, tho same comprising a cutting knife and means for moving the same, and moans for discharging the said molten masses into suitable receptacles.
“4. An automatic device for cutting or separating a. flowing stream of molten material into unformed molten masses of predetermined quantity, the same comprising a' knife and means for moving the same, a plurality of receptacles, and means for discharging the said molten masses into said receptacles.
“5. An automatic device for catting or separating a flowing stream of molten material into unformed molten masses, the same comprising a knife and means for moving the same, a plurality of receptacles, means for discharging the said molten masses into said receptacles, and means for intermittently moving said receptacles into position to receive the cut-off masses.”

In a suit brought by the Homer Brooke Glass Company against the Schram Glass Manufacturing Company (249 Fed. 228, 161 C. C. A. 264), the Circuit Court of Appeals for the Seventh Circuit has held the claims here in issue to be valid, and the decision in that case is [902]*902sufficient" answer to that portion of the defendant’s answer'which alleges invalidity, especially in view of the fact that no new evidence of such controlling importance as to compel a different conclusion has been here offered in support of the alleged invalidity. So that infringement is the only question to be here discussed and decided.

The decision here to be given will be contained in the answers to two questions: First, Does the defendant treat a flowing stream, of molten glass? and, second, Does the defendant’s cutting device cut, support, and discharge, or cut and discharge, the cut-off portion of the molten masses ? These questions will be considered in their order.

We can do no better here, in explaining briefly the purpose of the Brooke device and tire difficulties of prior methods in manufacturing glass which Brooke sought to overcome, than to quote from the opinion of Judge Evans in the Schram Case, supra. On pages 228 and 229 of 249 Fed. (161 C. C. A. 264, 265) he said:

“The patent to Brooke relates to an apparatus for cutting and distributing molten materials, particularly glass, and is of particular value to tbe manufacturer of fruit jars, bottles, and other similar glass objects used by the public in large quantities, the cost of which constitutes an important factor in their successful manufacture. While the art of making glass articles is old, it was, prior to Brooke’s device, deficient in a particular, an understanding of which is better obtained by a brief general description of the art to which it relates. In making articles of molten glass prior to this discovery, a considerable quantity of the molten material was taken from a furnace to a mold by a workman, called a gatherer, who, by the use of a ‘punty’ rod, injected into and twisted around in the molten mass in the furnace, first collected and then transferred it to a position over a mold of predetermined size into which the glass ran from the rod. Another workman stood by, and with shears cut this string or stream of .flowing glass when directed. The gatherer then twisted his rod, so as temporarily, to prevent glass falling off and until another empty mold was supplied, and then the operation was repeated. Machines for receiving this product, containing molds of predetermined capacity, were in common use, and, not infrequently, easy and ready method of substitution of one mold for another was provided. Some devices for receiving the molten mass in the mold, and for the prompt exchange of the molds, were patented, and at least one must be especially considered— the patent to Steimer, No. 549,404, issued November 5, 1895.
“Brooke’s contribution to the art consisted in producing an apparatus that would better, more rapidly, and more economically convey the molten mass from the furnace to the mold. Instead of the interrupted flow of glass, and the delayed method of transferring with a punty rod this substance from the large reservoir to the mold, in use prior to this discovery, appellee’s device permitted .the glass to flow continuously from the furnace, and the severing knives were made to act automatically, and means for supporting the severed stream were provided; the accumulated flow being poured into the opening of the next presented mold.”

On page 230 of 249 Fed. (161 C. C. A. 264) will be found a clear and brief description of the operation of the Brooke device, so that it is not necessary now to do more than refer to it; but from the brief description, as well as the description of the operation of the Brooke device disclosed by the specification, it is clearly apparent that a continuously flowing stream of glass, flowing by gravity, is the kind and character of stream which Brooke handles in the patent in suit.

The stream of flowing molten material and the stream of flowing molten glass are frequently referred to in the specification. The mech[903]*903anisui embraces an automatic device for cutting a flowing stream of molten glass, means for discharging the same, and means for shifting the molds to receive the severed glass, and reference in the specification is made a number of times to the cutting knives acting upon the flowing stream. The specification finally concludes by saying:

“Of course it will bo understood that 1 do not limit myself to the precise construction of devices here illustrated, as I consider myself to be entitled' to broadly cover all means for cutting or separating a stream of flotoing molten material inlo unformed molten masses and discharging the cut-off portions.”

The claims in suit are for an automatic device for—

(3) “Cutting or separating a flowing stream of molten material.”
(4) “Catting or separating a flowing stream of molten material.”
(5) “Cutting or separating a flowing stream of molten material.”

The claims not in issue are also directed to the same mechanism fed in the same way and they refer to—

(1) ‘Pin unsupported freely-flowing stream.”
(2) “An unsupported freely-flowing stream.”
(6) “A flowing stream.”
(7) “A continuously flowing stream.”
