 EAMMEBSCHLAa V. SCAUONI. 585 �4. Patent— Utilitt— Construction. �Where, previous to the invention, the article was not capable of being made by a machine or mechanical process then known, and being- made by hand was too expensive for general use ; and wbere, by reason of the invention, the article is made of superior quality and greatly cheapened in priee, and on these accounts haa created a new branch of industry, — the patent securing such inrentioa m ^entitled to a liberal construction. �In Equity. �Frost de Coe, for plaintiff. �Kitchen e Brown, for defendant. �Blatohfobd, C. J. This is a motion for preliminary in- junction on two patents. One is a re-issue granted to the plaintiff October 22, 1878, No. 8,460, for' an "improvement in waxing paper;" the original patent. No. 193,867, having been granted to him August 7, 1877. The specification of the re-issue says : �*' The object of this invention is to apply paraffine or other wax to paper, to render the same water-proof. This paper is adapted to confec- tionery, to prevent the adhesion of articles, one to another, or to the paper, and the paper may also be used in wrapping butter, cheese, cut- lery, and other articles requiring a water-proof protection. My improve- ment relates to a means for heating the wax, applying it to the paper, spreading or difCusing the wax into the paper, removing surplus wax, and then polishing the surface prier to winding the paper upon a reel. In the drawing, ligure 1 is a plan view, and figure 2 is a longitudinal section of the apparatus employed by me. The cylinders, a, b, e, are hollow. * * temperature, as in a calendering machine. * * * There is a trough, n, beneath the cj'linder, a, into which paraffine or other wax isintroduced, and the proxiraity of the rollers, a, b, to this trough insurea the melting of such wax, and the surface of the cylinder, a, takes up a layer of wax and applies it to the web of paper, «, that is drawn ofE the reel t and wound upon the reel w. The scraper, x, is applied to the cylinder, a, be- tween the wax trough and the place of contact with the paper, to remove surplus wax, and only allow a uniform layer of wax to adhere to the heated cylinder, a. The paper passes beneath the heated cylinder, b, with the plain surface of the paper next to the heated cylinder. This serves to beat the paper, and melt and diffuse the wax throughout the fabric of the paper, so as to render it thoroughly water-proof. The paper now is drawn over the stationary scraper, l, to remove any surplus paraffine, and then it is brought over the heated cylinder, c, with the waxed surface in contact therewith. By this cylinder, c, the paraffine is again fused and spread into and upon the surface of the paper, thereby ironing and ��� �
 * Each cylinder is supplied with steam to beat the same to the desired
