Mr. Justice STRONG delivered the opinion of the court. By the arrangement described in Graham’s reissued patent of 1867, and claimed as his invention, it is manifest that that part of the device called the rocker is prevented from sliding perceptibly on its bed and is kept true in its bearings by the arm or bar from which the journals are projected, the arm having also a long bearing in the box of the rocker. The journals, moreover, having bearings in the ears of the *274 bed, steady the rocker, resist any lateral movement, and prevent what is denominated- as wabbling. As the picker-staff is made to oscillate, its rocker rises and sinks upon the arm, and thus most of the friction caused by the play of the staff comes upon the shaft, or journal-bearing arm, and not upon the tread of the rocker or the bed-plate.

UpLaw has not yet analyzed Mason v. Graham. The absence of a flag is not a finding that it is good law.

Headnotes

  1. Patent Law — Claim Construction A patent for a picker-staff motion that claims a combination of a rocker with a bed and loose journal-bearing arms is not limited to any particular form of the journal-bearing arm or to arranging that arm in a slot in the rocker; it embraces every combination of a rocker with a bed and loose journal-bearing arms arranged to produce the result described in the specification. 90 U.S. at 268
  2. Patent Law — Anticipation Prior patents that each disclose a rocker and a bed but do not connect the rocker to the bed by loose journals or loose journal-bearing arms, and do not obtain the beneficial results of the patented invention, do not anticipate that invention and do not require construing the patent to cover only a narrow combination. 90 U.S. at 268-69
  3. Patent Law — Infringement Where an accused device performs the same function in substantially the same way as the patented combination, differences in the form of the journal-bearing arm or in its mode of attachment are immaterial, and infringement is established. 90 U.S. at 270-71
  4. Patent Law — Accounting for Profits — Measure of Profits Where an infringer sold the patented device both attached to a larger machine and separately, the profits realized on the devices sold separately furnish a better measure of the profits attributable to the infringement than a ratable proportion of the aggregate profit on the entire machine. 90 U.S. at 271-72
  5. Patent Law — Accounting for Profits — Credit for Infringer's Own Improvement An infringer who has reduced the cost of producing the infringing device through an improvement of his own is entitled to a corresponding credit in ascertaining the profits recoverable by the patent owner, because the savings resulting from the infringer's own invention are not due to the patented invention. 90 U.S. at 272
  6. Patent Law — Accounting for Profits — Settlement with Customers Where an infringer pays the patentees a sum to license his customers, under a written agreement expressly providing that the settlement shall not affect the patentees' right to recover profits or damages from the infringer and that the suit against him shall proceed as if the settlement had never been made, the amount so paid is properly excluded as a credit in computing the infringer's profits. 90 U.S. at 273-74
