tion S.N. 135,439 and of Patent No. 1,-622,957 where Figure 2 shows an actual Croquignole wind formed and in position just beyond the restricting clamp.
Other arguments of the defendants as to inferences which allegedly may be drawn of Croquignole winding in the original Mayer application do not require discussion. Mayer’s application S.N. 135,439 clearly sets forth matter pertinent to Mayer’s alleged invention set forth in the reissue patent sub judice not contained in Mayer’s original application.
R.S. § 4888, 35 U.S.C.A. § 33, provides that an application, the prerequisite to the issuance of a patent, shall contain “ a written description of [the invention] and of the process of using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to use the same ”. As was stated by Mr. Justice Stone in Schriber-Schroth Co. v. Cleveland Trust Co., 305 U.S. 47, 57, 59 S.Ct. 8, 12, 83 L.Ed. 34, “The object of the statute is to require the patentee to describe his invention so' that others may use it and ‘to inform the public during the life of the patent of the limits of the monopoly asserted, so that it may be known which features may be safely used or manufactured without a license and which may not’ and that the application for a patent cannot be broadened by amendment so as to embrace an invention not described in the application as filed, at least when adverse rights of the public have intervened.”,* citing Chicago & N.

I have italicized the words of Mr. Justice Stone which have particular pertinency in the circumstances of the instant case. A divisional application is an amendment of an original application. The same rules apply to divisions as to amendments. The divisional application, S.N. 135,439, is an amendment of Mayer’s original application S.N. 16,784. The amendment contained vital new matter, the introduction of end-to-scalp winding of a band of hair upon itself after clamping it at its roots near the scalp. This amended, divisional application, since it contained a new and vital step, must stand upon its own date, September 14, 1926, and cannot relate back in priority to March 19, 1925, the date of Mayer’s original application S.N. 16,784. Nor did Mayer actually claim Croquignole wind of a flat strand of hair after binding until his application S.N. 346,174 filed March 11, 1929. Unfortunately for Philad, rights of the public intervened in the form of Mayer’s British Patent No. 251,688, which was sealed August 12, 1926, upon an application filed with a complete specification on February 4, 1925.
The specifications of Mayer’s British Patent, No. 251,688 for “Improvements in or Relating to Permanent Hair Waving Appliances”, state, “This invention relates to permanent hair waving processes of the kind in which the hair is formed into flat strands, each of which is secured, at the end furthest from the roots, to a curler of substantially circular cross section, and wound thereon, each turn being laid upon the preceding turn.” This is a clear description of Croquignole winding. The specifications also provide for “ the preparation of the hair prior to winding on a curler, [including] the step of clamping the hair in a flat strand near the roots between the edges of metal or other rigid flat bars hinged together at one end and provided with means for fastening the other ends together, Here is the clamp applied to the band of hair before winding. The patent also states, “After the two clamps have been placed in position the flat strand of hair is moistened with a suitable solution such as hereinbefore indicated and then secured by means of a spring finger to a curler of substantial circular cross-section, and wound thereon, each turn being laid over the preceding turn.”
The drawings accompanying this patent, particularly Figure 7, show the clamp and a curl of hair wound in Croquignole fashion in position beyond it. Claim 1 of the British patent states, “In a permanent hair waving process of the kind set forth [in the specifications], the preparation of the hair prior to winding on a curler including the step of clamping the hair in a flat strand near the roots between the edges of metal or other rigid flat bars
