Opinion

ROGERS, Circuit Judge.

The United States granted to complainants on February 27, 1906, letters patent No. 813,841. of which they are still the sole and exclusive owners. The patent was issued for improvements in methods of treating cement and cement construction. The invention consists of a method of treating with a suitable organic acid or acid body a Portland cement construction for the purpose of making its surface “dust proof, oil proof, water proof and wear proof.” The invention relates to the surfacing after setting of a Portland cement construction, and is largely employed in surfacing cement floors which are subject to wear and abrasion. This abrasion of the surface raises continuously a fine dust containing free lime, which, is injurious both to health and to machinery. Any attempt to paint a Portland cement surface met the difficulty of the early peeling off of the paint, [712]*712due to the chemical action of the free lime upon the constituents of the paint, and it was generally understood that a Portland cement construction could not be successfully painted. Moreover, Portland cement construction, although hard and rocklike, is to a certain extent porous" and for that reason non-water proof and non-oil proof. The Toch invention was intended to overcome these difficulties.

The patentee, Maximilian Toch, is a chemist of distinction and is connected with Columbia University and the College of the City of New York. After three years of experimental investigation of Portland cements and of resins he claims to have discovered that the modicum of free lime present in the pores is the root of the dust and paint-scaling evil. Pie invoked the known chemical reaction of free lime in the presence of acid resins to produce resinate of lime as a means to sin end, and conceived the idea of applying with a brush a liquid acid resin to the surface of a Portland cement construction. He thus secured, after allowing time for penetration and chemical reaction, a resinate of lime to be. formed in situ in the pores of the Portland cement construction, to1 a depth of from one-eighth to three-eighths of an inch, which filled the pores and consolidated the structure. Thus the cement structure and the resinate of lime structure constituted a new composite substance said to be non-porous, insoluble in oil or water, and mechanically more solid and resistant than the Portland cement construction alone. The practical result it is said was a substantially new composite surface upon Portland cement construction which was liquid proof and wear proof, dustless and strong; and which would hold paint permanently. The problem of surfacing Portland cement construction against wear, as for floor purposes, and against weather, as for wall purposes, and for receiving and retaining paint, it is claimed was thus solved by him. The invention has gone into practical use to a large and increasing extent.

It is not claimed that Dr. Toch discovered the reaction ■ that takes place between lime and the acid resins. That it is admitted was .well-known. And he did not discover the characteristics' or qualifies of resinate of lime by itself. That also was well known. But it is claimed that he did discover that, in the surface pores of Portland cement construction after setting, there is just that modicum of free lime to react in those pores with sucli quantity of liquid acid resins as will deeply penetrate the pores when externally applied and form resinate of lime in situ. This it does in such a way as to substantially integrate with the solid portions of the “Portland cement construction itself, the resinate of lime extending down in rootlike forms in the pores of the Portland cement construction and solidly filling those pores—rock in rock—the whole producing a new composite surface partly Portland cement, partly resinate of lime mechanically strengthened and proof against abrasion and wear, and dustless, and at the same time liquid proof. And it is claimed that no one had ever actually done that thing or described that thing before.

Dr. Maximilian Toch describes his process in his specifications as follows:

“I first apply to the cement floor, wall, or other construction a filler prepared from a highly acid resin, such as Manila or copal gum. For the [713]*713preparation of the filler the resin is heated, together with a suitable vegetable drying oil or mixture of oils—as, for instance, linseed and cbinawood oils— under conditions which will substantially avoid the loss of volatile resin acids. This heating is preferably effected in vacuo, although the method^ technically known as ‘underheating’ may be used. The heating is continued until solution is effected, after which a suitable diluent, as benzol, acetone, turpentine, or naphtha, is added. One or more coats of this filler ma.y be applied to the cement. IPor the preparation of the second coating mixture the rosin is heated under such conditions as to expel a portion of the volatile resin acids and an increased proportion of vegetable drying oil is used. The solution is diluted as above and is preferably mixed with a suitable pigment, as oxid of iron or zinc or sulfid of zinc in proper proportion to give the desired shade. The mixture so prepared will dry in about five hoars to a hard and durable coating, in which no surface disintegration will occur, even after a long period of use.”

The complainants aver that the defendant, without any license from them and in violation of their rights and in infringement of their patent, has wrongfully used and caused to be used and still is using the inven - tion described in their patent. They ask for an injunction, preliminary and permanent, as well as profits and damages.

The defendant in an amended answer asserts (1) that Toch, the inventor, was not the first and original inventor of the alleged invention or improvement covered by the patent in suit, but that it was anticipated in the prior art; (2) that the alleged invention was not and is not an invention or discovery which could lawfully he made the subject of a patent under the statutes of the United States, in view of the prior public use.

The District Judge held the patent invalid because of two British patents which he regarded as anticipations of it, and on that ground dismissed the bill.

It appears that in 1884 a British patent, No. 5,237 was issued to Walley & Gare. The specification of that patent states that the invention consists:

“In protecting from damp, moisture or decay, and in varnishing and enameling and in some cases hardening or toughening stone, brick, tile, earthenware, cements, lime, and gypsum, plasters, metals, wood, fibrous materials, paper, yarns, threads, cords, ropes, and woven, knitted, and braided fibrous fabrics, by applying to or combining therewith a certain composition hereinafter described which is or may be made use of in reference to the said substances or materials by applying to the same as a varnish either alone or combined with ordinary paint or pigment.
“It is or may also be made to act when required as an enamel either alone or in combination with other known or suitable substances, when several coats of it are applied to the surfaces of the said substances or materials after the pores or interstices in such have become filled or saturated with it, and the said composition is or may also be made to harden or toughen more or less the said substances or materials (except metals) when they are soaked in or combined therewith.
