The suit is for infringement of the first and second claims of letters patent No. 504,944 granted to Rose; and of the first claim of letters patent No. 504,945 granted to Rose.
Claims 1 and 2 of the first of these patents read as follows:
“(1) A tubular metal stick for umbrellas or parasols, said stick being drawn down near one end so that the tubular end portion of the stick is reduced in diameter and increased in thickness as compared with the body of the stick, substantially as specified.
“(2) The combination of the tubular metal stick drawn down near one end so that the tubular end portion of the stick is of less diameter than the body, with the notch applied to said reduced tubular portion of the stick, and the ribs hung to the notch and fitted snugly against the efilarged body of the stick, substantially as specified.”
The second claim covers nothing new; the first embraces the entire invention. The “stick” is for use in an umbrella and consequently the claim covers its combination with the other parts of the structure —the circular “notch,” ribs and canvas top. The “notch” is fitted to the reduced circumference of this “stick,” just as it was previously fitted to the sticks formerly used. The second claim does not, there-' fore, add anything to the scope of the first.
The infringement of the latter is proved beyond doubt. The defense urged rests on a denial of its validity.
Is this defense sound?
We do not think the allegation that metal tubes with tapering ends, containing an equal quantity of metal throughout their length, —thus having an increased thickness of walls in the tapering ends,— were old is satisfactorily proved. That metal tubes with tapering ends, were old, may be conceded; but that the walls of the ends were so thickened is not clear. The uses for which these tubes were designed did not require such strengthening of the ends, and the surplus metal used to produce the thickened walls would be simply wasted. If any such tubes were previously manufactured it must have resulted as an unintentional incident of the method employed in their manufacture, and not from design. Granting, however, that such tubes were previously made, the fact does not seem important. They did not constitute umbrella “sticks” nor suggest adaptability to this use. What Rose did was to invent and construct a metal umbrella “stick,” having a new and useful feature — a tapering end so drawn down as to diminish the diameter of the tip, and part to which the “notch” is attached, without diminution of the metal, thus allowing the ribs and canvas to be folded closer than formerly, and materially increasing the strength of the “stick” where the strain upon it is greatest. We think this is more deserving of a patent, than much that has been adjudged patentable. If metal tubes, such as the defendants’ witnesses describe, existed, they did *471not, as before stated, suggest the conception embraced in this '•'slick.” At most they only assisted in embodying it. The invention resides in the conception and its embodiment. The existence of the old tube might have aided in the latter; certainly nothing more; and that would be unimportant. The evidence shows, however, that it did not do this; that Hose had no knowledge of the existence of such tubes; but accomplished the construction of those he required through experiment. For the reasons stated we cannot doubt the validity of the patent. The defendants did not doubt it, but admitted it, by the purchase and sale of umbrellas under the patent, until dissatisfaction and dispute arose respecting the prices they should pay. The admission is not, of course, an estoppel; but in view of the defendants’ presumed familiarity with the art, such an expression of judgment is evidence, and worthy probably of as much weight as that now expressed by their experts.
Claim 1 of the second patent reads as follows:
“'['ho within-described umbrella ease, the same consisting of a tube of leather slitted and provided with fastening devices at the upper end and having at the lower end an internal socket extending throughout the length of the projecting end of the umbrella stick, and fitting snugly thereto, and a ferrule applied to the lower end of said stick, substantially as specified.”
“Umbrella cases, consisting of a tube,” constructed of various kinds of material, “slitted and provided with fastening devices” at the upper end, were old at the date of the patent. Whether the “socket” and “ferrule” described, were also old, need not'be decided. The device covers these three elements. Whether the patent is valid or not, it is not infringed by tbe defendants’ case — from which the “socket” is omitted.
The object of tbis element in Eose’s case is to increase its circumference over the tip, and thus make it correspond there with the circumference at the “no tcli,” rendering the case uniform and smooth throughout. The defendants’ case is intended for their own peculiar umbrella, the tip of which is covered permanently with wood, so as to make its circumference correspond with that of the “notch,” thus dispensing with the necessity for a socket within the case. This wooden cover is not an equivalent for the omitted element in Rose’s case; for it is not a part of the case, but of tbe peculiar umbrella manufactured by the defendants. The defendants’ case cannot be substituted for Rose’s; it can only be employed advantageously on Ihe peculiar umbrella described. It thus appears that the two cases are entirely dissimilar in the respect stated; that the one cannot be used advantageously where the other is applicable. The defendants no doubt employ the wooden cover on their tip to dispense with the necessity of using Rose’s case. That they thus do it to avoid his monopoly does not, however, afford just grounds of complaint; they have a right to increase the size of their tip in this manner or any other, and thus dispense with the use of his case. If Rose had taken a patent for his umbrella and case combined, a different question would be presented. He did not do this, however, but took a separate patent for the case, because he desired and intended to obtain a monopoly in cases, not simply for the peculiar umbrella *472manufactured under Ms previous patent, but for all others to which it could be applied. The effort now made to read the patents together and to treat them substantially as one, covering the umbrella and case combined, is, of course, unjustifiable. The patent for the case must stand alone, as issued, and so considered it clearly does not cover any case from which either of its essential elements is omitted. The plaintiff’s argument in this respect, if sustained, would prohibit any modification in the form of the old umbrella which served to make the old cover fit it smoothly and tightly from' end to end, as the plaintiff’s fits upon those to which it is applicable.
The decree is reversed and the record remitted to the circuit court with directions to enter a decree in accordance with this opinion.
