useful result, and the only result hinted at is the effecting of a backward movement of the cover before it is locked in place. The applicant accepted the awkwardly drawn claim which the examiner offered him, and from the other two claims, which at the end he had pending, eliminated the words “to effect a backward movement of the cover,” which the examiner had criticised as “attempting to claim the apparatus, by referring to its capabilities, instead of its construction,” and the three claims issued as set forth supra. But in view of the specifications, which remained unchanged from first to last, we cannot hold that the action of the Patent Office so broadens these claims as to warrant a construction that would cover a type of operating handle which merely holds the cover in place, without first shifting it so as to allow the escape of water and steam. The order is reversed, with costs, but without prejudice to a renewed application for injunction, should complainant be able hereafter to show the manufacture or sale by defendant of kettles similar to those manufactured before the agreement of April 30, 1906.

FOREST CITY FOUNDRY & MFG. CO. v. BARNARD.
(Circuit Court of Appeals, Sixth Circuit. February 8, 1910.)
No. 1,979.

1. PATENTs ($ 66°)—ANTICIPATION.—UNCLAIMED FEATURE of PATENTED DEv1CE. A patentee is entitled to a beneficial use of a feature of his device if it actually exists, although he did not specifically claim it, and it may constitute an anticipation of a later patent. [Ed. Note.—For other cases, see Patents, Cent Dig. §§ 79–81; Dec. Dig $ 66."] 2. PATENTs ($ 328*)—ANTICIPATIoN—FLUID DISTRIBUTor. The Barnard patent, No. 580,151, for a fluid distributor, held not anticipated, and valid.

Appeal from the Circuit Court of the United States for the Northern District of Ohio.

In Equity. Suit by William N. Barnard against the Forest City Foundry & Manufacturing Company. Decree for complainant, and defendant appeals. Affirmed.

W. T. Arnos, for appellant.
W. T. Read, for appellee.

Before SEVERENS and WARRINGTON, Circuit Judges, and SANFORD, District Judge.

SEVERENS, Circuit Judge. The complaint made by the bill in this case is of the infringement of letters patent No. 580,151, granted to W. S. Barnard as assignor to William Nichols, April 6, 1897, for improvements in fluid distributors. The defense is that the patent is invalid because of anticipation by earlier patents; and by two, especially, one of which is a patent to Rhodes, No. 185,965, granted

[ocr errors]

January 2, 1877, and the other a patent to Forster, No. 220,277,
granted October 7, 1879. The first of these last-mentioned patents
was for improvements in water distributors, and the second, for im-
provements in lawn sprinklers. The court below held that the patent
in suit was not anticipated, and that it was valid. This is the sole
question controverted here.
Barnard's invention, as he says in his specification, contemplated
two leading features; a chamber wherein the fluid is caused to re-
ceive a reverberatory and gyratory motion, and a discharge-opening
through which the fluid is delivered from the chamber and immedi-
ately released without passing, as in other distributors, through an
elongated passage or tube. For these purposes he devised a discoid
form of chamber—that is to say, consisting of two circular plates
parallel to each other and a few inches apart which were connected
at their outer edges by a circular band or plate of the same diameter,
the whole resembling a very short drum. Tangentially to this struc-
ture he attached at its periphery an inlet tube through which the in-
coming fluid would enter the chamber and striking against the inside
of the wall of the chamber would be whirled around the inside of the
wall until it made the circle, and impinging upon the stream still com-
ing in would be diverted inwardly thereby and would proceed in an-
other circle inside of the first and so on until the convolutions came
to the center of the chamber where, through an opening in one of the
circular plates or heads of the drum-shaped chamber, the fluid would
be discharged and scattered by the force and direction already given
to it over an area somewhat proportioned to the force and violence
with which it was moving when discharged. No other “mouth piece”
was contemplated. The theory is that the fluid is converted into
spray by its impinging upon the inner wall of the chamber, and by
its impinging one part upon another by its convolutions, and also by
its being impeded where its course is changed to leave the chamber.
A witness likened the operation of the fluid to that of a “whirlpool.”
Fig. 3 of the drawings shows a cross-section of the chamber, the
adit pipe and the discharge-opening, B. The outer rim is the circular
wall of the chamber. The claims are these:
“(1) In a nozzle for spraying liquids a
chamber substantially circular in one plane
of section provided with an outlet-port and
with an inlet-passage, the axis of which
lies in the plane of a circular section and
between a diameter and a tangent of such
section ; whereby a rotary motion is im-
parted to the liquid in the chamber by the
force of the inflow which motion is retained
after it escapes from the chamber, substan-
tially as described.
“(2) In a nozzle for spraying liquids a
chamber of substantially circular form in
cross-section, provided with a tangential in-
let-port, the axis of which lies in the plane
of the circular section, and with an outlet-
port delivering in a direction transverse to
the axis of the inlet-port.
“(3) A spraying-nozzle comprising a cham-
ber of approximately circular form in cross-section, provided at its periphery

with a tangential inlet-port, and at its center with an outlet-port, the axis of which is transverse to that of the inlet-port. “(4) A spraying-nozzle comprising a chamber having two approximately circular side walls, and an approximately circular peripheral connecting portion, said chamber provided with an inlet-port adapted to deliver the incoming fluid against the connecting portion, and one of the said side walls being provided with an opening for the discharge of the fluid.”

No question is made of the efficiency and utility of this device; and it seems to us, in view of the object sought to be attained, to exhibit a good deal of ingenuity in contriving the means for the method. But it is contended by the defendant, the appellant here, that similar devices to accomplish the same purposes had been invented and patented by Rhodes in 1877 and Forster in 1879. Of these, the Forster patent is the one most worthy of consideration as an anticipation, and we shall therefore dismiss the other remarking only that we find nothing in it which contains a suggestion of Barnard's invention.

Forster's was a device for a lawn sprinkler. Fig. 2 of the drawings with a brief explanation will suf- 222 & fice for an understanding of it. 37 & .

A is an up-standing water pipe, e is a plug having several spiral grooves, f, in its periphery, C is the sprinkler-nozzle composed of a tubular body, c, and a flaring mouthpiece, d. The plug, e, is driven tight into the lower end of the tubular body, c, and the function of the spiral grooves upon its edge is to provide water passages which impart a spiral movement to the water as it passes through the nozzle, and, in connection with the flaring open mouthpiece, break up the stream of water into a fine spray. We have followed the inventor's language closely. The points of resemblance to Barnard's device are very scanty. Counsel for the appellant claim that the spiral grooves perform the same function as the inside of the circular sides of § Barnard's chamber does. It is possible that in Forster's device the water, to some extent, impinges upon the inside of the “tubular body” though he does not suggest it. But he would be entitled to the benefit of that feature, if in fact it existed. Goshen Sweeper Co. v. Bissell Carpet Sweeper Co., 72 Fed. 67, 19 C. C. A. 13; Goodyear Rubber Tire Co. v. Rubber Tire Wheel Co., 116 Fed. 363, 53 C. C. A. 583; Stilwell-Bierce, etc., Co. v. Eufaula Cotton Oil Co., 117 Fed. 410, 415, 54 C. C. A. 584; Eames v. Worcester Polytechnic Institute, 123 Fed. 67, 71, 60 C. C. A. 37. But he seems to construct his device in such form that the spiral streams of water shall converge at the nozzle and be there broken into spray. Assuming that some slight disintegration is effected by directing the water upon the sides of the tubular body, this would be only one of the several united means of effecting the desired object employed by Barnard; and taken as a whole his method is a very different way of breaking up the water from that of driving it through the reverberatory chamber of Barnard's patent. There is not in Forster's invention the provision of means at all adapted to effect such a violent tumult of the fluid as

is created by the means contrived by Barnard. Again in the Barnard patent there is no nozzle which co-operates with antecedent means in reducing the water to spray. That has been done in the chamber, and the orifice is a mere exit for the spray. We think there is no fair ground for regarding any previous invention to which our attention has been called as an anticipation of the patent in suit. This result accords with that of the Circuit Court, and its decree should be affirmed, with costs.

LURTON, Circuit Judge, participated in the hearing and decision of this case, but is no longer a member of this court.

AMERICAN STEEL & WIRE CO. OF NEW JERSEY v. DENNING WIRE & FENCE CO.

(Circuit Court, N. D. Iowa, Cedar Rapids Division. January 11, 1910.) No. 46.

1. PATENTs (§ 234*)—INFRINGEMENT—MACHINE PATENT. To constitute infringement of a patent for a machine the infringing machine must be substantially identical with that of the patent in the result attained, the means of obtaining that result, and the manner in No. its different mechanisms operate and co-operate to produce that TeSult. 2: Note.—For other cases, see Patents, Cent. Dig. § 370; Dec. Dig. § 4.*] 2. PATENTS (§ 235*)—INFRINGEMENTs—MACHINEs—INTERMITTENT AND CoNTINUous OPERATION. Machines or devices in which the different parts are arranged and constructed to operate continuously are different in principle from those in which the parts are arranged to operate intermittently and alternately with each other, and one is not an infringement of the other. [Ed. Note.—For other cases, see Patents, Cent. Dig. § 371; Dec. Dig. § 235."] 3. PATENTs (§ 328*)—INFRINGEMENT—WIRE FENCE MACHINEs. The Bates patent, No. 577,639, for a machine for making wire fence, construed, and held not infringed.

4. WoRDS AND PHRASES--“CUT.” The word “cut” most usually signifies to make an incision with a sharp instrument; to cut or sever by the application of a sharp knife or edged instrument of some kind.

No. 577,639, issued by the United States to Albert J. Bates February
23, 1897, and now owned by the complainant. Preliminary and per-
manent injunctions are prayed restraining defendant from further in-
fringing said claims. The defendant denies the alleged infringement,
and resists the granting of a preliminary injunction. The single ques-
tion for determination is, Has the defendant infringed complainant's
patent?
The patent is for a combination of four groups of mechanisms into
a machine for making woven wire fence fabric. It was adjudged
valid by a decree of this court in March, 1908 (160 Fed. 108), in a
suit between these same parties, and the defendant restrained from
further infringing the claims above mentioned and claim 5. The de-
cree was affirmed by the Court of Appeals in April, 1909. 169 Fed.
793. Since the former suit was commenced the defendant has made,
and authorized to be made, four kinds of machines, other than the two
involved in that suit, with which it makes and authorizes others to
make a woven wire fence fabric substantially the same as that made
by the complainant's machine; two of which are made under letters
patent of the United States No. 816,538 issued to Joseph M. Denning,
president of the defendant company, March 27, 1906; one under let-
ters patent No. 923,778, issued to said Denning June 1, 1909; and one
upon which there is no patent. It is the use of these machines with
which to make such wire fence fabric, and the sale of them to others
for that purpose, that complainant now seeks to enjoin as an infringe-
ment of its patent. The two machines involved in the former suit are
referred to in the preliminary proofs upon this hearing as machines
Nos. 1 and 2, and those involved in this suit as Nos. 3, 4, 5, and 6.
Models of the latter named machines are in evidence and numbered
accordingly. To sustain the charge of infringement of a patented
machine the infringing machine must be substantially identical with the
one alleged to be infringed in (1) the result attained; (2) the means
of obtaining that result; and (3) the manner in which its different
mechanisms operate and co-operate to produce that result. If the
machines are substantially different in either of these respects, the
charge of infringement is not sustained. Machine Co. v. Murphy, 97

Co. v. Interchangeable B. B. Co., 106 Fed. 693, 45 C. C. A. 544.
In Machine Co. v. Murphy, above, it is said:
“In determining the question of infringement, the court or jury, as the case
may be, are not to judge about similarities or difference by the names of
things, but are to look at the machines or their several devices or elements in
the light of what they do, or what office or function they perform, and how
they perform it, and to find that one thing is substantially the same as an-
other, if it performs substantially the same function in substantially the same
way to obtain the same result, always bearing in mind that devices in a pat-
ented machine are different in the sense of the patent law when they perform
different functions or in a different way, or produce a substantially different
result. * * * It is necessary in every such investigation to look at the mode

of operation or the way the device works, and at the result, as well as at the means by which the result is attained.”
