Adams v. Keystone Manuf'g Co.
Opinion of the Court
An interlocutory decree was rendered in this case several months ago, finding that defendant the Keystone Manufacturing Company had infringed the first claim of the patent granted to complainant on the 15th of October, 1872, for an “improvement in corn-shellors,” and a reference made to Henry W. Bishop, Esq., one of the masters of this court, to take proofs and state an accounting of the gains and profits received by defendant from such infringement, and also such damages as complainant may have sustained by reason thereof. The master has. filed his report, finding that the defendant company has manufactured and sold 688 two-hole shellers, 683 four-hole shellers, 236 six-hole shellers, which infringe complainant’s patent; that the profits on the two-hole machines amounted to S10 on each machine, on the four-hole machines the profits amounted to $20 on each machine, and on the six-hole machines the profits amounted to $30 on each machine, making an aggregate profit on all the machines so made and sold of $27,620, for which amount he recommends that a decree be entered. It also appears from the proof that, after the court had entered an order awarding the complainant an injunction pendente lite, unless the defendant would file a bond, with surety to be approved by 'the court, conditioned for the payment of such amount as the court might, on final hearing, award the complainant, the defendant, having filed such bond, changed the construction of its machine by substituting a fluted shaft, with four projecting corners or angles, in place of the picker shaft, or round shaft with pickers or projections, which defendant had before used. This fluted shaft, the master finds, is the equivalent of the picker shaft before used, and the profits are awarded on machines with the fluted shaft the same as
The first of these- exceptions goes to the allowance of profits on machines containing the fluted shaft; defendant contending that this fluted shaft does not infringe the complainant’s patent. The first claim of the patent is for the combination with the. corn-sheller of a series of wings, wheels, or projections, so arranged on a shaft as to revolve in the same direction as the corn is running, and so placed relative to the throats as to force into the machines all misplaced or hesitating ears, substantially as specified. The specifications of the patent provide for placing this picker or beater shaft directly over the stream of ears of corn, just at the throat of the machine, or entrance into the shelling mechanism, so that the projections on the shaft will force or compel the ears to enter the shelling mechanism, and the patentee says in his specifications:
“Space enough'is left between the revolving wings and the bottom of the throats to allow of a single ear to pass freely beneath without contact, but sufficiently near to strike an overriding ear, and force it, and other ears in contact therewith, or in the road thereof, ahead rapidly into the shelter, clearing the passage for the corn following. It is evident that the form or shape of the beaters or projections upon the revolving shaft may be varied in many ways, and the result accomplished. I therefore do not limit myself to the form shown.”
By fluting or grooving this square shaft between the corners, defendant has manifestly made a shaft with “projections,” which do just what the patentee intended the wings, wheels, or projections on his shaft should do, — that is, force into the machine all misplaced or hesitating ears,— and the angles or flanges made by the grooving is one of the. many forms of projections on the shaft which the patentee suggests may be adopted. The proof also shows that some kind of a beater or picker shaft is absolutely essential to the operation of defendant’s maehinp, and the substitution by defendant of this fluted shaft, in place of its old picker shaft,— that is, the shaft with pickers or projections upon it, — is a tacit admission by defendant of the necessity of this feature to its machine. I therefore find that the master committed no error in taking into his account the profits on these machines with the fluted shaft.
The second, third, and sixth exceptions insist that the master should have found the difference between the profits on the defendant’s machine and what would have been the profits by the use of other well-known picker shafts in use prior to complainant’s invention. It is a sufficient answer to these objections that the proof shows no beater or picker shafts in public use prior to the complainant’s invention which would perform, or were intended to perform, the function of- complainant’s shaft, either in complainant’s or the defendant’s corn-shellers. •
The fourth, fifth, seventh, and all the subsequent exceptions assigned may be considered together, and, in substance, insist that the master had
The defendant, as the proof shows, is the competitor of these Adams machines made hy the Sandwich, Joliet, and Marseilles Companies. A glance at the mechanism of the two shelters — that is, the Adams and the defendant’s — shows, even to a person who is not an expert, that there can be but very little, if any, substantial differelice between the cost of the Adams machines and the defendant’s of the same capacity, and the circulars introduced in evidence substantiate this conclusion. The complainant, to establish the extent of the defendant’s profits, called witnesses familiar with the cost and selling price of the Sandwich, Joliet, and Marseilles machines, and showed what the profits of these manufacturers were on the different sizes of machines made by them, and what proportion of these profits were fairly attributable to the com
