    N° 26,666 A.D. 1902 Date of Application, 3rd Dec., 1902 Complete Specification Left, 26th Aug., 1903—Accepted, 1st Oct., 1903 PROVISIONAL SPECIFICATION. A Spring Stopper for Medical Tubes; and like Purposes. We, William Summerskill, M.R.C.S, and Ernest Julius Link, Merchant, both of 92 Harrow Road, Leytonstone, London, do hereby declare the nature of this invention to be as follows: — This invention refers to spring stoppers, nozzles or spray diffusers for apply- 6 ing anesthetics such as ethyl-chloride in the form of spray, and is applicable for supplying scents or essences and for like purposes. It consists of a collar, socket or sleeve which is cemented or tightly fitted to the nozzle of the tube or bottle, from each end of which collar, there projects a support for the closing mechanism. The back support is a lug or cam with 10 central aperture, and the former is preferably two lugs connected by a pin or rivet, upon which is pivotted an arm connected to a small rubber faced disc which forms the cover or closing cap of the aperture or mouth of the tube. From the centre of the arm on its underside and half way between the disc and the pivot above referred to, are two small lugs also connected by a pin F-> or rivet, which form the attachment for the end of a sliding bar, which extends backward through the back support or lug before mentioned, and projects about an inch beyond same, and terminates in a small button or knob. On the tail or back part of this bar a small spiral spring is placed, whose function is to keep the tail extended, and thereby keep the disc at the other end of the 20 bar tightly closed. The underside of the bar has a notch which engages with an edge or pro¬ jection on the back support, and serves to keep the disc in the open position when so desired. The method of use is to press the bar forward overcoming in so doing the resistance of the spring, and then by giving the bar a slight 2$ downward pressure, cause it to lock on the back support. To close it, it is only necessary to raise the bar when the coiled spring closes the stopper auto¬ matically. Dated this 3rd day of December. 1902. S. S.
