Opinion

MANTON, Circuit Judge.

On May 23, 1911, there was granted to the appellee Frank R. Craig letters patent No. 993,034 “for improvements in the means and methods of demagnetizing paper” on an application filed January 9, 1908. Craig transferred the patent to the appellant. In that agreement of transfer, he covenanted and agreed that any further instruments necessary would be executed by him and any further acts and things which would be necessary to carry into full effect the true intent and meaning of the agreement between the appellant and the appellee Frank R. Craig would be done so that the appellant would become the sole and exclusive owner of the invention and “all improvements thereon and modifications thereof which would become the property of (said Craig) or which should come under his (Craig’s) control.” He agreed that he would not manufacture or sell any. machines made in accordance with the said letters patent as long as the appellant should manufacture a machine in which gas is employed. At the time of this transfer, Craig was a large stockholder and officer of the appellant. He later parted with the control of the stock, resigned as an officer, and thus severed his connection with the company. Eater, appellee the Static Control Company, Inc., was incorporated, and he became interested as an officer of that company, as did his wife and son-in-law, the appellees Sarah R. Craig and Andrew J. Smith. This corporation proceeded to manufacture and sell a device which is claimed to be an infringement of the patent in suit. The appellees say that their structure is manufactured under and pursuant to letters patent No. 1,286,132 which were applied for by the appellee Smith and assigned before issuance to the appellee Sarah R. Craig. This patent is for a printing press and was applied for August 31, 1918, and granted November 26, 1918. The appellant sought to prove on the trial that Smith was not the real inventor of this patent, but that one Cohen, now an officer and stockholder of the appellant, was the true inventor. The devices made under each of the letters patent relate to means for removing static electricity from paper. When paper is passed through a printing press, especially in dry and cold weather, the friction of various parts of the machinery upon each other and upon the paper causes the latter to be charged with static electricity. The sheets of paper, as they are discharged from the press, tend to adhere together, and it is very difficult to handle the same on that account. There is a tendency of the fresh and still moist ink upon the paper to offset from one sheet to the other. It is therefore desirable to not only discharge the static electricity from the paper as it comes from the press, but also to dry the ink. This is accomplished by passing the paper as it comes from the press over a series of small gas burners. [74]*74arranged in a row transversely along the path of the paper so that the well-known action of a current of .heated air may discharge the static electricity. On account of the danger of fire, from such a device, it becomes necessary to provide automatic means by which, if the motion of the press stops so that the paper would remain stationary over the' gas. burners, the flames thereof shall be automatically extinguished. The claims of the appellees’ patent in suit are as follows:

“1. The combination of a reciprocating carriage, a burner carried thereby and provided with a cock and means for automatically actuating the cock during the movement of the carriage.”
“7. The combination of a reciprocating carriage, a longitudinal burner movable laterally therewith and automatic means actuated by the movement of the carriage for controlling the admission of gas to the burner.”

i The appellant seeks the following relief: (a) That its patents be held to be valid and infringed by the appellee’s device; (b) that the invention, patent No. 1,286,132 be declared an invention of Herbert Cohen, an officer of the appellant, and that letters patent for said invention be mandatorily transferred from Smith to it; (c) that the appellees be restrained from selling the devices for removing static electricity from paper because of the agreement entered into between Craig and the appellant. It seems to be conceded that the device manufactured and sold by the appellee is not that illustrated and described in the patent in suit, No. 993,034; but it is urged that for the purpose of this Suit, this patent must be taken as a basic or pioneer one covering all the devices intended to remove static electricity from paper, and that the claims thereof should be given the fullest interpretation. It is argued that the appellee Frank R. Craig, having applied for and having obtained this patent and having sold the same to the appellant for a valuable consideration, thereafter entered into a conspiracy with the other appellees for manufacturing and selling a device of the same character, is now estopped from attempting to justify his case “by straining interpretations of the language of the claim.”

The devices of both patents are applied to printing presses which have a reciprocating or back and forth traveling support for handling the printed sheets delivered from the press. Each time this support moves back and forth, it delivers a printed sheet. On the rearward movement of the carriage, the sheet is carried with it, and on the forward movement of the carriage, a corresponding forward movement of the sheet is prevented in a manner familiar to the printing art, so that the rear end of the carriage during the forward movement of the latter sweeps from one end of the halted sheet to the other. In both devices, a gas burner is mounted adjacent to this rear edge of the travelling support so that the flames or heated air from the burner may similarly sweep over the sheet from one end to the other. In the patent in suit, the adjustable stops are provided and so located on the part of the printing press fixed relative to the carriage, that at or near the end of the travel of the carriage in either direction, one of said stops engages the handle of a valve fixed on the carriage and in the fuel supply line for the burner and lowers the gas flame or, if the common expedient of a pilot light is present, extinguishes the flame. The arrangement is such that during the major travel of the support relative to the [75]*75sheet, the underlying burner is operating at full blast. The sole object of this is to economize the amount of gas to be used. No other object is apparent or stated. The means of closing or partially closing the supply valve for the burner apparatus was designed to operate for the gas economy purposes indicated at or near the opposite ends of the path of travel of the reciprocating support. It is clear that said means were designed to operate and could only operate during the movement or by the movement of the carriage. It was not designed to operate, nor could it be operated, as a result of the stoppage of the carriage at a point well removed from the opposite' ends of its path of travel as might frequently occur when human hands have in charge the starting and stopping of the printing press and its power driving means. In the invention of the Smith patent, pursuant to which appellee’s device is made, this contingency of the fallability of human hands is guarded against so that if a stop occurs, the failure to shut off the burner would be guarded against. If there was such a .stop, the halted sheet overlying the flaming burner would ignite with possibly dangerous results.
