the applicant to have claimed this combination, then, after rejection, erased his claim and taken a patent without it with no reservation as to any part of the machine described therein, operated as an estoppel upon any disturbance of the right of the public thereto through a subsequent patent which disclosed no new invention in respect to this part of the machine. It would be a fraud upon the public at large, if Graham, by this application, could reappropriate the subject matter to which that patent related. O'Reilly v. Morse, 56 U. S. 15 How. 62 (14: 601); Odiorne v. Amesbury Nail Factory, 2 Mason, 28; Smith v. Ely, 5 McLean, 76; James v. Campbell, 104 U. S. 356 (26: 786). If prior patents ever operate as an abandonment, they must so operate at the time they issue, and not after the right has been forfeited by some other reason. Miller v. Bridgeport Brass Co. 104 U. S. 350 (26: 783); Mosler Safe & Lock Co. v. Mosler, 127 U. S. 354 (32: 182); Godfrey v. Eames, 68 U. S. 1 Wall. 317 (17: 684); Suffolk Mfg. Co. v. Hayden, 70 U. S. 3 Wall. 315 (18: 76); Sickels v. Falls Co. 4 Blatchf. 509. There was no established royalty or license fee, and no evidence showing actual damages of any kind. On the contrary, it affirmatively appeared that there were no damages. A complainant cannot, pending a reference to a master, manufacture, either by instruments executed by himself, or by negotiations with strangers, an ex post facto measure of damages to be applied to the trespass of defendants for which this reference is ordered. beam; that unite it to a stiff tongued or single frame machine; that enable it to automatically conform to the surface of the ground; that yet enable the driver to controllably adjust the point of the guards at any desired angle; that permit the finger beam to be folded for transportation; and that accomplish all of these results independent of the main frame. The courts which have passed upon the Graham patent have considered its first and second claims as covering a machine accomplishing the objects and employing the means enumerated. Graham v. Gammon, 3 Bann. & Ard. 8; Graham v. McCormick, 5 Bann. & Ard. 244; Graham v. Geneva Lake Crawford Mfg. Co. 11 Fed. Rep. 145; Graham v. Plano Mfg. Co. 33 Fed. Rep. 917. The 1867 patent was intended to cover one part of the Graham machine, and the 1868 patent another and distinct part. McMillan v. Rees, 5 Bann. & Ard. 274. It is a good defense to a suit on a reissue to show that the commissioner exceeded his authority in granting it. Mahn v. Harwood, 112 U. S. 359 (28:667). The statute only gives a reissue when the original is defective by inadvertence, accident or mistake. Leggett v. Avery, 101 U. S. 256, 259 (25:865, 866). The grant of a subsequent patent for an invention is an estoppel to the patentee to set up any prior grant for the same invention, which is inconsistent with the terms of the last grant. Barrett v. Hall, 1 Mason, 473. An established royalty, to afford any measure of damages, must be one which has been adopt-original application, in order that in a new one ed at the time of the trespass. The value of the invention must be proved by witnesses who state under oath, and subject to cross examination, the particular data upon which they base their estimates. Complainant having failed to show any uniform rate established by concurrent usage, and having failed to furnish any other competent measure of damages, and having waived profits, must recover nominal damages only.

This class of inventions may be experimented with in public; and it has been repeatedly held that two or three years is a very reasonable time in which to complete an invention of this kind.

There was never any delay on Graham's part, or on the part of his solicitors, of which he had any knowledge, in filing or prosecuting his applications. This being the case, his two applications must be considered as a part or con tinuation of the same proceeding, so that, on this question, the complainant is entitled to the same protection as if the patent sued on had been issued on the first application; and the circumstances are such that, if necessary for the complainant's protection, the first application should be considered as filed at the time it was placed in the hands of Munn & Company, the first of 1864. cation and extent.

Gammon, 3 Bann. & Ard. 9, Judge Blodgett said: "It is contended that in the model of the Zug patent, which is put in evidence, there is a provision for the rocking or rolling of the finger bar; but I must say that I can find no such feature, either in the specification or model." The patent to E. Ball, of October 18, 1859, does not have Graham's mechanism, nor any rocking motion of the finger bar; it does not have this vibratable link, his arm H, nor his swivel joints M and M'. Graham v. Gammon, 3 Bann. & Ard. 10. In the Bartlett and Dodge mechanism, there is no possible device in the patent for the rocking, and no device or means by which the finger beam can be rolled or tilted in the manner provided in the Graham patent. Graham v. Gammon, 3 Bann. & Ard. 10. The patent issued to Andrew Wemple, January 29, 1867, was before the court in Graham v. Gammon, but was held insufficient as a ground of defense. Graham v. Gammon, 3 Bann. & Ard. 11. These several patents do not embody the entire invention secured to the complainant in his letters patent. Imhaeuser v. Buerk, 101 U. S. 660 (25:947). In his specification, just before the claims, Graham says: "Having thus described a machine embodying all my improvements, I declare that I do not limit my new combinations to the particular forms represented in the drawings, but intend to vary the form and construction of the members of the combinations, or to use equivalent members in their places, as circumstances may render expedient." This clause should be regarded as a part of the claim and as explaining its meaning, appli In an action at law for the infringement of a patent, the plaintiff can recover a verdict for only the actual damages which he has sustained; and the amount of such royalties or license fees as he has been accustomed to receive from third persons for the use of the invention, with interest thereon from the time when they should have been paid by the defendants, is generally, though not always, taken as the measure of his damages; but the court may, whenever the circumstances of the case appear to require it, inflict vindictive or punitive damages, by rendering judgment for not more than thrice the amount of the verdict. Seymour v. McCormick, 57 U. S. 16 How. 489 (14:1024); Tilghman v. Proctor, 125 U.S. 143 (31 666); Locomotive Safety Truck Co. v. Pa. R. Co. 5 Bann. & Ard. 518; Mowry v. Whitney, 81 U.S. 14 Wall. 653 (20:866); Littlefield v. Perry, 28 U. 8. 21 Wall. 229 (22:581). Where a patentee has clearly suffered a material loss by the defendant's use of his invention, and has produced all the evidence of which the nature of the case admits to establish the amount, there has never yet been a case in which his recovery has been restricted to nominal damages. McKeever v. U. S. 23 Pat. Off. Gaz. 1529. The general rule that an established royalty or license fee constitutes the true criterion of damages can only be applied where there is a fixed and established price at which a license is granted. Black v. Munson, 14 Blatchf. 265, 2 Bann. & Ard. 626; Matthews v. Spangenberg, 14 Fed. Rep. 351. An established license fee is competent and satisfactory evidence of the value of a patent right, because the price which it commands between those who sell and purchase it is the best criterion of its value. [2] There being no established patent or license fee in the case, in order to get a fair measure of damages, or even an approximation to it, general evidence must necessarily be resorted to. Suffolk Mfg. Co. v. Hayden, 70 U. S. 3 Wall. 320 (18:78). He is the first inventor in the sense of the Act, and entitled to a patent for his invention, who has first perfected and adapted the same to use; and until the invention is so perfected and adapted to use, it is not patentable.

Rep. 517. creeing that the defendants had infringed those claims, awarding a recovery of profits to the plaintiff from the 12th of August, 1870, the date of the assignment of the entire patent by the patentee to the plaintiff, and referring it to a master to take an account of profits and damages. On the 21st of July, 1884, the master made a report awarding a sum of money in favor of the plaintiff to which both parties filed exceptions. On a bearing the court sustained some of the defendants' exceptions and overruled all others, and rendered a money decree in favor of the plaintiff. Both parties prayed appeals to this court, but the plaintiff did not perfect his appeal. Since the record was filed in this court, the plaintiff has died, and his administrator, Peter Whitmer, has been substituted in his place as appellee. Only claims 1 and 2 of the patent are involved. The specification states, among other things, that one object of the improvements which constitute the invention set forth in the patent, is to obtain a greater capacity of movement in a floating finger beam, while retaining its connection with a gearing carriage that is drawn forward by a stiff tongue; that, to that end, the first of the improvements of the patentec "consists of the combination of the finger beam with the gearing carriage by means of a vibratable link extending crosswise to the line of draft, a draft rod extending parallel with the line of draft, and two swivel joints, the one for the vibratable link, and the other for the draft rod, so that the finger beam can rise and fall at either end, and rock forward or backward independently of the gearing carriage, while maintaining its connection with it;" and that his "next improvement consists of the combination of the finger beam, gearing carriage, vibratable link, draft rod, and swivel joints, with an arm connected with the finger beam, to enable it to be rocked for the purpose of setting its guard fingers at any desirable inclination to a horizontal line." His acts are to be construed liberally; he is not to be estopped by licensing a few persons to use his invention to ascertain its utility, or by any such acts of peculiar indulgence and use as may fairly consist with the clear intention to hold the exclusive privilege.

The mere fact that a new article is shown in the drawings of a patent for a machine would not of itself be an abandonment of the new article, which would properly be the subject of a different patent, until the statutory forfeiture of use for two years had been incurred.

Mr. Justice Blatchford delivered the opinion of the court: The specification further says: "My improvements may be embodied in a machine having the finger beam arranged in advance of the axial line of the shaft or arbor of the driving wheel, or arranged in the rear of that axial line. In the former case, the vibratable link that connects the finger beam with the gearing carriage will be arranged in advance of the driving wheel, and in the latter case in the rear of the driving wheel. In the former case, also, the rod hereinbefore called a 'draft rod' (because the strain to which it is subjected is a pulling strain) becomes a pushing or thrust rod, and connects the inner end of the finger beam with the rear of the gearing carriage. In the former case, the radius bar for the reel and raking platform connects with the rear end of the gearing carriage, and in the latter case with its front end. I prefer to construct a harvesting machine with the finger beam in the rear of the line of the axle of the driving wheel, and, as a description of such a machine, perfected by The defenses set up in the answer were want my improvements, will enable them to be fully of novelty and noninfringement.

"The arrangement of the lever N, chain or cord p, and upright r, substantially as shown, for raising the outer end of the finger bar I, as set forth.' On the 30th of December, 1865, the Patent Office rejected claims 1 and 2 on a reference to prior patents. On the 24th of March, 1866, the ap plicant erased claims 1, 2 and 3, and substituted for claim 1 the following: 1. "The combination of the finger bar I and bar J attached to the frame A by means of the universal joint or swivel K, in the manner and for the purpose herein specified." On the 4th of April, 1866, the Patent Office rejected this substituted claim 1, by a reference to a prior rejected application and to a prior patent. On the first of October, 1866, it allowed the two remaining claims applied for, which had been numbered 4 and 5 originally. On the 18th of June, 1867, the applicant filed a withdrawal of the amendments filed March 24, 1866, the effect being to limit the invention claimed under the patent to the two claims allowed October 1, 1866, and the patent was granted July 23, 1867, as No. 67,041, with those two claims, which in no manner re late to any question involved in the present suit.
