    N° 2164, A.D. 1901 Date of Application, 31st Jan., 1901 Complete Specification Left, 30th Apr., 1901—Accepted, 15th June, 1901 PROVISIONAL SPECIFICATION. Improvements in Syringes for Surgical and other purposes. I, George Frederick Noel Taylor of 5G Ludgate Hill, London, E.C., L.R.C.P. & S.E., L.F.P. & S.G. & L.M. Edinburgh, do hereby declare the nature of this invention to be as follows: — This invention relates to improvements in syringes-used for surgical and b other like purposes, and is especially applicable to those known as hypodermic syringes The object of this invention is to provide a syringe constructed in such a manner as to enable the same to be absolutely sterilized by simple means, such for instance as bringing the said syringe to boiling point in water, after the removal of the rubber ring on the piston rod which could be placed in an anti- 10 septic solution, and also to prevent leakage between the barrel and the needle, moreover the cost of manufacture is reduced. My improved syringe consists of a graduated cylinder or barrel made of glass in the usual manner (except that the needle end of the cylinder is made solid for the purpose to be hereinafter described), a piston rod, piston or plunger, 1 5 with indiarubber packing ring, and a metallic tube or “ needle ”. This said metallic tube or “ needle ” is provided at the end which is fixed in the syringe with a bulb of solid metal at such a position round the needle that when sealed in the solid end of the cylinder of the syringe, the bulb shall occupy the middle of this solid portion of the glass cylinder or barrel aforesaid. 20 This needle is sealed into the said solid portion of the glass by any convenient and effective means while in a state of fusion. As both the glass and the metal employed for all practical purposes contract and expand equally or thereabouts when brought to the boiling point there is no liability to leakage due to unequal expansion or contraction, nor any danger of the glass barrel cracking.
