    N° 10,691 A.D. 1894 Date of Application, 1st June, 1894—Accepted, 7th July, 1894 COMPLETE SPECIFICATION, An Improvement in Surgical Syring-e and Insufflater Nozzles. We Arthur William Down and Hubert Vincent Down both of Nos. 5 & 7 St. Thomas’s Street Borough in the County of London trading together in partnership as Surgical Instrument Manufacturers under the style or firm of “Down. Bros.” do hereby declare the nature of this invention and in what 5 manner ibe same is to be performed, to be particularly described and ascertained in and by the following statement :— The subject of our invention is a new form of watertight union applied to the nozzles of syringes, douches, powder insufflaters or other similar instruments for surgical and medical purposes, and we make it in the following way :—On the 10 inner surface of the proximal end of a circular or other shaped tube or nozzle made of glass metal vulcanite celluloid or other substance we make or mould a groove or depression (hereafter referred to as the collar) and therein place as washer or packing a piece or ring of indiarubber asbestos or other suitable material projecting inwardly so as to serve as a socket for and hold secure any tapered tube 15 inserted into it thus forming a water tight union between the tube or nozzle first mentioned and the inserted tube. It can also be made in the reverse way that is to say by putting the ring before mentioned round the nozzle or tube to be inserted, in which case the outer tube would be made conical in order to receive it. The invention is intended to be applied and used for surgical and medical purposes, 20 more particularly in connection with tubes made of glass (so as to be easily rendered aseptic) as for example all tubes or syringes used for injecting liquid or powder into the vagina, throat, rectum, ear, nose and other cavities or wounds in the human body. Our invention is illustrated in its application to a surgical syringe intended for 25 rectal and vaginal injections in the accompanying drawing, wherein A A is the rectum nozzle B B the vaginal nozzle 0 the collar and D the rubber washer or packing. Having now particularly described and ascertained the nature of our said inven¬ tion, and in what manner the same is to be performed, we declare that what we 30 claim is : The novel method of joining the parts of a surgical syringe or powder insufflator —both parts being made of glass or other suitable material and one socketed into the other and retained there by means of a rubber ring contained in a groove or depression whereby a water tight union is obtained. 35 Dated this 1st day of June 1894.
