Hicks v. Kelsey

APPEAL from the Circuit Court for the Northern District of Illinois; the case being this:

Hicks obtained a patent for an improved wagon-reach, and filed a bill against Kelsey, charging infringement and praying the usual relief. The defendant answered, denying the novelty of the alleged invention, and also denying infringement.

The thing called a 'wagon-reach'-that is to say, a pole or shaft connecting the front and rear axles of wagons or carriages, and having an upward crook or curve in it, so as to allow the front wheel, which, when a carriage is turned, goes against the reach if straight, to pass under it-had confessedly long been made, and was public property. These had been made of wood, necessarily for the sake of strength of a certain thickness, and consisted of one piece, strengthened by straps of iron attached to each side of the reach. The supposed improvement of the plaintiff consisted precisely and only in leaving out the wood in the curve and bolting the iron straps together, whereby the curve became all iron and less bulky, but in all other respects having the same shape and performing the same office as before. About all this there was no dispute whatever. Instead of being bolted together, the straps might be welded so as to make the curve consist of solid iron.

The question was whether this change of material-making the curve of iron instead of wood and iron-was a sufficient change to constitute invention,-the purpose being the same (namely, to turn the wheel under the body of the wagon), the means of accomplishing it being the same (namely, by a curved reach), and the form of the reach and mode of operation being the same.

Witnesses were examined, whose testimony went to show that the iron reach had advantages over those of mere wood, or of wood and iron. One said that of thirty-five, which he had made in about two years, none had come back broken, or needing repairs; that this was not the case with the old sort.

Another said:

'My experience is that, in those made of wood and iron, the wood between the iron plates in summer contracts and loosens the bolts.'

Another said:

'Hicks's reach being iron, the two plates come together as one whole substantially soldered. In the wooden one, the moment the shrinkage becomes such that the bolts become loose, each has to take its own part, and the transit of the trucks, moving from the right to the left, turning the friction from that, takes each separate strain from one and throws it on to the other, so it makes only the thickness of the one side-the one piece of iron where otherwise it would be two plates together. The crooked part, right at the crook, would break, according to that arrangement, because the other part is stronger. It will break whenever it gets so it will vibrate, at the weakest point.'

The court below decided that plainly there was nothing but a change of material, and that this-the purpose, means of accomplishment, form of the instrument, mode of operation, being all as in the old reach-was not a sufficient change to constitute invention. It accordingly dismissed the bill. From its action herein this appeal was taken.

Mr. S. A. Goodwin, for the appellant:

This invention does not consist in the mere substitution of a particular material for other material which had been previously used for the same purpose and in the same way. The invention consists in the production of a certain described article by a certain described mechanical process, which process, viewed as a whole, is new in itself. That process is, the making an ordinary wooden reach of two separate parts, in splicing those parts at the front and rear ends by a particular and new mechanical arrangement to a curved metallic intermediary splice, made substantially solid in two plates, or one casting, so that a new article is produced by a new mechanical arrangement or device,-a new curved reach. This article has added advantages and increased utility over the old wooden curved reach improved upon. They are shown in the proofs. Indeed, the matter is intelligible without proofs. The curved reach is indispensable, to prevent the wheel, when the carriage is turned and one of the front wheels put under it, from rubbing against the reach, lifting it up, and upsetting the carriage. But a curved reach must be made. One is rarely found in the natural growth of a tree. The curved part, when made, is necessarily weak, being usually made of wood sawed across the grain. To give strength the whole wooden reach has iron plates along it, fastened on both its sides with spikes or bolts. The wood and the iron shrink unequally, and the bolts all become loose. But when the central part is all made of iron alone, leaving the ends, for the sake of lightness, to be of wood alone, all this is obviated.

We say, then, that this new material in the crook or curve; with the new method of attachment at each end (the splice) to the two wooden parts; with the new construction of the reach as a whole; with the new operation in consequence of the change; with the increased utility and beneficial results, thus incontestably proved, bring this patent within the principle of all the cases as a patentable invention.

There are many cases in which the materiality of an invention, whether it be a machine or a process, can be judged of only by its effect on the result, and this effect is tested by the actual improvement in the process of producing an article, or in the article itself introduced by the alleged invention.

No opposing counsel.

Mr. Justice BRADLEY, having stated the case, delivered the opinion of the court.
