51 F. 763 | U.S. Circuit Court for the District of Eastern Missouri | 1892
The patent involved in this suit was considered and susfaáned in the case of Manufacturing Co. v. Heincken, 43 Fed. Rep. 75. It was there held that the claim of the patent should be interpreted as one for a corncob pipe in which the exterior interstices of the cob am filled with a plastic, sell-hardening cement; that the making of such a pipe did not involve invention of a very high order. Nevertheless, as the result had been to convert a poor article into a good one, and to supply something to the trade which was new, and the merits of which were generally recognized, there was enough of invention to sustain the patent. The views thus expressed iu the Heineken Case commend themselves to this court, and they are accordingly adopted.
The testimony found in the record, to the effect that in a few instances plaster of Paris had been used, before the date of the patent, to fill such small cavities or cracks as were occasionally found in the cob, is also insufficient to establish the plea of anticipation. No samples of pipes in the manufacture of which plaster of Paris had thus been used were produced, and it is not pretended that plaster was so applied to the whole exterior surface of the bowl, with a view of improving the quality of pipes. It appears to have been applied, if at all, solely with a view of remedying defects that were sometimes found in the cob. The Barbed Wire Patent, (Washburn & Moen Manufg Co. v.

The question of most importance is whether defendant has infringed. It is admitted by the answer that on some occasions prior to the commencement of this suit the defendant made corncob pipes, and in so doing filled the exterior interstices of the cob, after it was turned and bored, with a mixture of finely pulverized corncob and cornstarch. His contention is that the mixture in question was pressed into the interstices in a perfectly dry state by hand, while the cob was rapidly revolving on a spindle, and that the bowl was subsequently -coated with shellac, to hold the dry mixture in place; but it is conceded that before the mixture of cob dust and starch was thus applied the cob was in
The court is forced to regard both of the processes of manufacture last described as an infringement of complainant’s patent. While the complainant has always used plaster of Paris as a filler, yet it is not limited to the use of that particular substance. The patentee conceived that by filling the small pores of the cob from the outside with some mixture that would harden, and resist the action of heat, the bowl of a corncob pipe would be rendered more durable, without losing its capacity to absorb nicotine. The idea was a good one, though not involving a high order of invention, and it appears to have led to the manufacture of a cheap corncob pipe, superior to any that had before been made, which immediately came into great demand. That the patentee did not intend to limit himself to a filler consisting of plaster of Paris is obvious from the wording of the specification and claim. Speaking of the bowl or head of tho pipe, he says: “These are made of corncob, in which the interstices are filled with plaster of Paris, or other suitable plastic mass or cement;” and the claim is for “a new article of manufacture, a smoking pipe made of corncob, in which the interstices are filled with a plastic, self-hardening cement, substantially as and for the purposes set forth.”
The court is accordingly of the opinion that the claim of the patent is infringed when any plastic mixture such as ground corncob and starch, or ground corncob and shellac, which will set or harden, is applied as a filler to the exterior surface of the bowl of a corncob pipe, and that it makes no difference whether the plastic, self-hardening mass is moistened and mixed before it is applied to tho bowl, or whether it is so moistened and mixed in the act of applying it. The view taken by the court leaves the defendant at full liberty to varnish or paint the howls of corncob pipes according to the old method. It also leaves the defendant at full liberty to press dry corncob dust into the exterior interstices of the cob, and to apply a coating of varnish to hold the dry dust in place, provided there is no such admixture of the two substances in the process of manufacture as to form a plastic, self-hardening mass.
A decree and an injunction will he ordered, in accordance with the foregoing views.
