Opinion

REED, District Judge.

This suit was brought by appellant to restrain the alleged infringement by defendant of claims 1, 2, and 3 of patent No. 634,923, issued to Theo. P. Walter, October 17, 1899, and claim 9 of patent No. 810,098, issued to the same Theo. P. Walter, [812] January 16, 1906, the application for which was filed March 28, 1905, both for improvements in corn-huskers. The defendant denied the infringement, alleged that both of the patents were anticipated by prior patents and devices set forth in the answer, and were lacking in patentable novelty and void. The Circuit Court dismissed the bill, and complainant appeals.

In the specification of the first patent, or patent No. 634,923, the patentee says:

“The object of the present invention is to improve the construction of com-huskers, and to provide a simple, inexpensive, and efficient device adapted to fit the hand of the operator, and prevent the same from being crippled; and a further object * * * is to provide a corn-husker having an adjustable hook adapted to be arranged in different positions to suit the hand of the operator, and capable of being readily replaced when worn. The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated, and pointed Out in the claims hereto appended.”

Claim 1 of this patent is as follows:

“A corn-husker provided in its body portion) with a series of openings, in combination with a husking-hook adapted to be fitted into any one of said openings, and retaining means for said hook.
“2. A corn-husker comprising a body portion provided with a transverse series of slots and an adjustable hook adapted to be arranged in any of the slots and provided at its shank with an arm, extending in the opposite direction from the engaging portion of the hook and secured to the inner face of the said body portion, substantially as described.
“3. A corn-husker comprising a body portion provided at intervals with slots, and a hook capable of adjustment on the body portion and provided at its shank with an arm extending through one of the slots and detachably secured to the inner face of the body portion, substantially as described.”

The patentee at first claimed as his invention the adjustability of the hook upon the plate or body of the huslcer. This claim was rejected by the Patent Office upon reference to a number of prior patents. The patentee acquiesced in this rejection, canceled the original claim 1, slightly amended claims 3 and 4, and presented two new claims, one of which is claim 1 of the patent as above quoted. The other is as follows:

“2. A hand com-ihusking implement having in combination .therewith a husking-hook and means whereby the position of said hook may be shifted from one point of the body of the implement to another.”

The Patent Office rejected this claim ¡upon reference to the patent to Schmeltzer, No. 146,842, January 27, 1874, and said that claim 1 “may possibly be allowed upon its specific construction.” The pat-entee then amended, his new claim 2, by inserting the word “separable” before the words “husking-hook.” The claim as so amended was again rejected upon reference to the Brown patent, No. 57,283, August 21, 1866; Schmeltzer, No. 146,842, January 27, 1874; Hagen, No. 259,683, June 20,1882; Burton, No. 626,854, June 13, 1899. The patentee again acquiesced and presented claims 2 and 3 of the patent as finally allowed and as above set forth. It thus appears that the pat-entee acquiesced in the repeated rejection by the Patent Office of his original and amended claims for an adjustable hook upon the plate or [813] body of the husker, and accepted the narrower claims of the patent which are for the specific construction or method of attaching the hook to the body of the plate as described. It is settled by the repeated decisions of the Supreme Court and of this court that, when an inventor seeking a patent for a broad claim acquiesces in a rejection of the same by the Patent Office and substitutes therefor a narrower one, he will not be heard to insist that the construction of the claim allowed shall include that which has been rejected; also, that a claim as allowed under such circumstances must be construed with reference to the rejected claims and the prior state of the art, and will not be so interpreted as to cover either what was rejected by the Patent Office or disclosed by prior devices. Corbin Cabinet Rock Co. v. Eagle Rock Co., 150 U. S. 38-40, 14 Sup. Ct. 28, 37 L. Ed. 989; Computing Scale Co. v. Automatic Scale Co., 204 U. S. 609-617, 27 Sup. Ct. 307, 51 L. Ed. 645; National Hollow B. B. Co. v. Interchangeable B. B. Co., 106 Fed. 693-714, 45 C. C. A. 544; St. Louis Street Flushing Mach. Co. v. American Street Flushing Mach. Co., 156 Fed. 574-581, 84 C. C. A. 340.

The patentee and the complainant as his assignee are, therefore, each estopped from insisting that the patent as allowed covers the broad claim for a hook adjustable upon the body of the plate as was originally claimed. Each of the claims 1, 2, and 3, therefore, must be limited to the specific method of attaching the hook to the body of the husker by means of an arm or shank fitted into an opening or slot in the plate. Is it a patentable novelty to so attach the hook, or is it shown by the prior devices? The standard husker, a device not patented, but which was put in evidence by the defendant, is conclusively shown to have been in public use since 1883, 15 years before the application for this patent was filed. That device is the same as that of this patent, unless the method or means of attaching its hook to the plate distinguishes it from the device of the patent. In referring to these two devices, the standard husker, and the husker of the patent, the complainant’s expert said:

“So far as the underlying spirit or idea involved in these two devices is concerned, I believe it may be properly said that the difference between the two resides in the facts that the standard husker is a fixed and permanent structure while the Walter husker is a detachable and adjustable structure. Thus broadly considered it may fairly be said that this is the only difference.’’
