6,673 FOR IMPROVEMENT IN WASH.BoARDS. Reissued letters patent No. 6,673 granted to It. P. Duff for an improvement in wash-boards, held, not infringed by the manufacture of wash-boards made in accordance with the discription contained In letters patent No. 201,658 granted to Charles EVtlrts.
In Equity. This is an action for infringement of reissued letters patent No. 6,673, granted October 5, 1875, for improvements in wash·boards to the complainant as asignee of WesHy Todd. The original patent bears date February 7, 1871. The specifications of the reissue state thai the nature of the invention "consists in the construction of a sheet-metal wash-board with a rubbing face longitudinally and transversely corrugated or ribbed, whereby such rubbing surface shall be made up of a series of projections, bounded by a series of horizontal, vertical, and angularly shaped grooves. The rubbing face somewhat resembles the face of a rasp or file in general appearance, though the projections are less sharp and angular." There are three claims in the reissue which are as follows:
"(1) A sheet-metal wash-board, having a series of raised projections, B, each bounded by longitudinal and transverse grooves or depressions, substantially as set forth; (2) in a sheet-metal wash-board the projections, each bonnded by grooves or depressions, in combination with raised projections, C, in the bottoms of the illterlying grooves, substantially as set forth; (3) a8 a new article of manufacture, a sheet-metal wash-board, haVing a rubbing face longitudinally and transversely ribbed or corrUgated. substantially as set forth."
Complainants' boards are known in the trade aE:ithe "Globe," and are so stamped. Defendants' boards are known in the trade as the "New Era," and the "Great Western," and are so stamped. The pattern of the Great Western is simply an enlargement of the pattern of the New Era. Defendants' boards are made in accordance with the description contained in letters patent No. 201,658, dated March 26, 1878, granted to Charles Everts, one of the defendants, which description is as follows:
"The object of this invention is to furnish an improved wash-board, the zinc rubbing plate of which shall be so formed as to give a great amount of friction to the clothes rubbed upon it, and at the same time shall be so formed as not to injure the said clothes. "The invention will first be described in connection with the drawing, and then pointed out in the claim. A represents the wooden frame of the washboard, which is constructed in the usual way. B is the zinc plate, which is secured to the frame, A, in the usual way. The plate, B, has transverse ridges, C, made with inclined sides formed across it, one of which sides may be made with a steeper inclination than the other. Upon the plate, E, and at right

angle1'l with the ridges, C, are formed short ridges, D, one end of which ridges, D, meets the ridges, C, and their other ends stop at a little distance from the next ridge, C. 'rhe ridges, C, D, thus form series of rows of T-shaped ridges, the ends of the cross-bars of which meet and form a continuolls ridge. In the spaces between and parallel with the short ridges, D, are formed depressions, E. The plate, E, may be attached to the frame, A, with the C, running across, or up and down, as may be desired."
The claim in this patent is as follows:
mediate longitudinal separated ridges, the lines of direction of said ridges being at right angles to each other, and between which ridges inclined rubbing surfaces and soap pockets are formed, substantially as shown and described."

TREAT, J. It is not the purpose of the court to enter upon a minute description or analysis of the original patent or reissue ; nor of the alleged anticipation thereof. The decision of the United States supreme conrt in Duff v. Sterling Pwnp Co. 107 U. S. 636, S. C. 2 Sup. Ct. Rep. 487, furnishes very little aid .for the present inquiry. In that case it was held that the Torldpatent was limited to the form of the longitudinal and transverse grooves with protuberances thereon, the said grooving being at right angles. That case seems not to have determined definitely whether the said Todd patent orits reissue was valid. It decided that the defendant's wash-board in that case was not an infringement of the Todd patent, even properly limited. The question of novelty and utility looking to the validity of the patent, and also the infringement alleged are before the court as ifunde(Jided by the supreme court, whether the said patent and its reissue could be up: held, considering the state of the act and prior patents, is more than doubtful. It must suffice, for the purpose of this case, that whether said Todd patent was valid or not, under a proper construction of its terms and the limitations thereof suggested by the United States supreme court, the defendant is guilty of no infringement. Bill dismissed, with costs.
