Steiner Fire-Extinguisher Co. v. Holloway
Opinion of the Court
This is a bill in equity for an injunction and an account, alleging infringement by the defendant of letters patent No. 172,442, dated February 10, 1874, on application filed January 5,1874, granted to John H. Steiner for improvement in chemical fire-extinguishers. The infringement charged relates solely to the fourth claim of the patent, which is for the following combination:
“(4) A chemical fire-engine, consisting of a wheeled frame provided with a generator or extinguisher, and with a hollow-journaled reel, N, the latter having its journal connected permanently to the generator by a pipe, M, and provided with a hose, 0, coupled to it as shown and described.”
The patentee disclaims any novelty in the hollow-journaled reel itself, and in his specifications states:
“I am aware that a hollow-journaled reel, such as used by me in this engine, is not new, and therefore I lay no claim thereto except in connection with the generator and connecting pipe as shown.”
Although by the defendant’s answer almost every possible defense is pleaded, no proof was introduced to support any one of them except that of prior invention, and in support of that only four prior patents were filed, and no other proof of prior publication or known use was produced. The defendant, who has been a leading manufacturer of chemical fire-extinguishers since 1872, in his own testimony admitted the infringement, and substantially admitted the novelty and patentability of Steiner’s fourth claim. It is proven that the defendant has desired to obtain a license from the complainant, and the admissions in his testimony and the weakness of his defense cast some doubt upon the seriousness of this contest.
Some difficulties with regard to the Steiner fourth claim suggest themselves upon an inspection of the claim. They arise from apparent want
Anothcrdifliculty which suggests itself upon first impression iswliether, after the reel and the generator are permanently connected, they do not each operate just as before, remaining simply an aggregation of separate elements, without any now result produced by their union. But, contrary to this first impression, all the proof which has been produced, including the testimony of the defendant himself, tends to show that not only is the efficiency of the machine as to its readiness for instant use greatly improved by having the connection between the hose and tlie generator permanent, and the hose so attached that it can be used without uncoiling more than is actually required, but that the hollow journal itself acts as a revolving receiver for the gas and water, and effects a inore permanent commingling of them, and also more perfectly neutralizes any free acid which may be forced from the generator, and that it eliminates the risk of the escape of the gas without the water. Thus it is claimed Unit the hollow journal performs a new function, and avoids a difficulty encountered in other contrivances in which there was a liability of alternate discharges of gas and water, the two not being properly commingled, and also avoiding the risk of a discharge of free acid which had not been entirely neutralized by thorough mixing. This, if true, is a new and beneficial result, due to the patented combination, quite apart from the more mechanical convenience of having the hose and the generator permanently attached one to the other, and it relieves the claim from the objection which was fatal in Hailes v. Van Wormer, 20 Wall. 353, and Thatcher Heating Co. v. Burtis, 121 U. S. 286, 7 Sup. Ct. Rep. 1031.
As showing the utility of the Steiner combination, it is testified that since it has come into use it has become an essential part of all chemical fire-extinguishers of the class on which the defendant uses it, and that there is no market for those which do not have it; and as evidence that it did require invention to contrive it, there is proof that, although the difficulties which it is said to meet were well known to many manufacturers, who were all trying to improve their machines, no one discovered its advantages until Steiner introduced it, since which it has been ac
