42 F. 54 | U.S. Circuit Court for the Northern District of Illnois | 1889
The bill in this case charges the infringement by defendants of the first claim of patent No. 275,947, granted April 17,1883, to Gustavus B. Sanborn, for a “split pulley,” and of claims Nos. 2, 3, 4, and 5 of patent No. 351,064, granted October 19, 1886, to Wallace H. Dodge, assignee of Charles McNeal, for a “wooden pulley,” and asks an injunction and accounting. The devices covered by both these patents, and their utility, is aptly described in the second paragraph of the San-born patent, as relating to “split pulleys made of wood, or mainly so, such as are used on shafting for driving machinery, and which are split, or made in separate sections or halves, to provide for putting them on or taking them off their shaft laterally relatively to the shaft, whereby they may be hung or removed without disturbing the shaft, and without interfering with other pulleys or devices on the shaft, or the hangers carrying the shaft.” The principal feature covered by these two patents is the division of the pulley by a zigzag line, so that the irregular surfaces, when brought together, will interlock, and thus aid in preventing displacement of the parts on the line of separation, — split pulleys being an old device, and the patents now in question being only for improvements on them. The defenses interposed are: (1) That the defendant is agent in the city of Chicago for the sale of pulleys manufactured by the Milburn Gin & Machine Company of Memphis, Tenn., and that bjr certain dealings and transactions between the complainant company and Wallace H. Dodge, the president of the complainant company, and J. D. & T. H. Milburn, and the Milburn Gin & Machine Company, said Milburn Gin & Machine Company were licensed and authorized to manufacture the pulleys in question, which were sold by the defendant, as the agent of said gin and machine Company. (2) That the claims of which infringement is charged in the respective patents involved herein are void for want of patentable novelty in the devices therein described. (3) That defendants do not infringe.
In regard to the alleged license or permission to the Milburn Gin & Machine Company to manufacture the pulleys' in question, the proof
Here, then; we have the fact established that in February, 1885, complainant was making split pulleys substantially like those now in controversy, under a shop right to use the patents Nos. 260,462 and 276,-330, which were owned by the said Wallace H. Dodge, who then was, and still is, the principal owner in complainant company, and manager of its affairs; that Dodge, for the purpose of obtaining means whereby to continue the business of the complainant company, assigned half these two patents to the Milburns, and the Milburns, in turn, licensed the Milburn Gin & Machine Company to enter upon the manufacture of split pulleys in said two patents, and the complainant company proceeded to furnish the Milburn Gin & Machine Company with instructions in the art of manufacturing split pulleys, and with drawings and plans for the construction of such pulleys, substantially identical with the form of construction for such pulleys provided for in the McNeal patent, and that the complainant acquiesced in and aided and encouraged the Milburn Gin & Machine Company in entering upon said manufacture.
I think, from the facts disclosed, the inference is fairly justifiable that McNeal; as the foreman of the complainant company, had substantially perfected whatever improvement the McNeal patent shows in the construction of split wood pulleys, at the time the Milburn Gin & Machine Company sent their employe to complainant’s factory for instructions, and that in instructing and starting the Milburn Gin & Machine Company in such manufacture the complainant, knowing that the said gin and machine company only intended to manufacture under the Dodge and Philion and Wallace H. Dodge patents, still gave the Gin and Machine company to understand that the approved form of manufacture under said patents was that for which plans, drawings, and instructions were given to the said Gin and Machine company’s agent. I think it very clear that McNeal made whatever invention there is covered by his patent as an employe of the complainant, and intended the complainant1 to have the benefit of it. This is shown by the fact that he transferred his application for a patent to Wallace H. Dodge, the president
All the dealings and relations between Dodge and the Milburns, and the Milburns and the Milburn Gin & Machine Company, and between the complainant and the Milburn Gin & Machine Company, shown in the proof in this case, satisfy me that Dodge represented and spoke for the complainant company, and that the complainant company understood that the Milburn Gin & Machine Company was expected, under its license from the Milburns, to make just such pulleys as the complainant was then making, or might thereafter make, under any acquired patent. It therefore seems dear to me that the complainant, under the facts disclosed in this case, is estopped from complaining of the manufacture of split pulleys, such as are in controversy in this case, and such as are covered by the specifications and claims of the McNeal patent. It may also, I think, be fairly insisted that, inasmuch as the complainant company allowed the McNeal patent to issue to Wallace H. Dodge as owner, that whatever rights of manufacture are given under said patent inure to the Milburn Gin & Machine Company under the contract between Dodge and the Milburns, and the license from the Mil-burns to the Milburn Gin & Machine Company.
The Sanborn patent was not purchased by the complainant until some time in December, 1886, and I do not think it necessary to discuss or consider whether that patent came within the provision for the purchase of subsequent improvements in the contract between Dodge and the Mil-burns or not, as I am abundantly satisfied that the machines sold by the defendants do not infringe the first claim of that patent. The view I have taken in regard to the legal effect of the dealings between the complainant and the manufacturers, for whom defendants were acting as agents in the sale of the pulleys in question, relieves me from the necessity of passing upon the question of novelty raised by the defendants in this case. The bill is therefore dismissed for want of equity.
