SYRINGE.
inmate;
' To all @vl-*1.0m z't may concern A Be it known that I, MORTIMER Birma citi-- zen of the United States, residing at indianapolis, Marion county, and State of In diana, have invented and discovered certain new and useful Improvements in Syringes,- of which the following is a specification.
`My invention relates to hypodermic syringes and its object is to provide a device of this class in which all the parts that come in contact with the liquid to be injected may be made of glass so that the article will be entirelyantiseptic; in which the closure for normally sealing the liquid contents within the syringe barrel may be displaced to permit the dischargeof the contents withoutV the necessity yof breakingl such closure or projecting the needle through the same, andin which the device is placed in condition ready for injection of the contentsby a sini-Y ple manipulation of the needle.
`With these objects in view my invention is embodied in preferable form in the device hereinafter` 'described and illustrated in the accompanying drawings.
In these drawings, Figure 1 is aside view i in elevation of the device ldrawn to the same j size as that of the syringe, Fig.,2, a. central vertical section enlarged beyond the size of the syringe; Fig. 3, a cross section on the line, 3--3 of Fig. 4, and Fig. 4, an
enlarged detail vertical section of the lower end of the syringe barrel.
' l In these drawings,-1 is the barrel of the 35" syringe and 2 the plunger thereof. Both are made pf glass. The liquid suiiicient in amount `for'a single hypoderrnic injection is placedjwithin the barrel Aand is adapted to be contained therein until the injection is to the barrel being tightly sealed by ofthe plunger and the the syringe. The
be made, the enlarged head closure at the other end of lower end of the barrel is reduced and tav lhollow cap `6.
ered to form an extension `3, 1n which is orrned a restricted passageway l4, leading from the .interior of the barrel' to' a valve chamber 5, which is formed by the wall of a This cap Y is preferably -of metal lto obtain strength and is adapted to' Specication of Letters Patent.

be cemented on the tapered surface of. the extension 3, its upper end abutting against the shoulder 7, formed on the'exterior of the barrel at the junction of the main por-.
curved seat for the valve is provided in the lower end of the extension 3, whereby said valve 1s adapted to snugly iit against the Patented Mar. 7,1916.
`and is preferably spherical in form. A.
outletend of the passageway 4 and thus close said passageway against the escape of- ]iquid, whenever 'the valvev is pressed against said extension. The cap 6 is threaded interiorly and is engaged by the threads of a needle 9 which is provided with a central longitudinal'channel 10 as is usual -and which by means of the screw threads is longitudinally' adjustable with respect to the cap 6. The eng 'of the needle that is inclosed within t e cap is provided with a head which-'is adapted to bear against the ball valve 8 and when the needle is screwed.
inwardly as shown in-Fig. 2, it will force the valve against its seat in the extension 3,
thus closing the passageway 4 andpreventing the escape of liquid the barrel. The surface of the head of the needle which is adapted to bear against the valve is provided with radial grooves 11 which permit the .liquid to pass beneath the ballV valve, when the latter is -released from the passageway 4.
The under side of the head of the needle is adapted to closely seatagainst the lower from -the interior of end wall of the cap. To insure a close joint, 1
a sealing gasket 12 may be provided on .the
underside. of the needle head, althoughthe close joint may be'otherwise obtained as by a beveled edge. Thefn'eedle is provided with a knurle'd surface 13 beyondnthe extremity Y of the cap 6 so that the needle may be read- -ily grasped and turned in order to place the device in operative condition. This Vknurled portion terminates in a shoulder 14 against which vpresses the end of-a suitable sheath 15, which serves as a protecting cover for the needle. This sheath may be made of gelatin, celluloid, metal or other material.
rIhe operation of the `device. is as follows The needle is normally projected inwardly as far as it will go, thus holding the valve 8 tightly against the seat in the lower end of the barrel and closing the outlet therefrom, so as to prevent the escape of the liquid contents of the syringe. "When it is desired to inject the contents, the knurled portion of the needle is grasped -by the hand of the operator and given a few turns which will serve to move the needle outwardly carrying its head down upon the inner face of the cap 6, to make a tight joint and thus prevent the escape of liquid around the threads, and at the same time releasing the pressure on the ball valve which is thereupon free to move within its chamber. The
operator then removes the sheath from the needle and the contents may be discharged through the needle by forcing the plunger inwardly which action carries the liquid .through the valve chamber and around the valve andthroughthe grooves 11 into the central passage-way of the needle. It will be seen that with this construction the liquid contents are kept out of contact with any metallic parts until the injection is to be made and that during the operation of the device the only metal with which the contents Come in contact is that of the cap and needle. In many hypodermic needles now in use a construction is provided whereby a diaphragm or other temporary closure must be broken bythe projection of the needle therethrough. In such devices there is danger of particles of the ruptured membrane or other closure becoming mingled with the contents of the syringe and either stopping the needle passageway or being forced through the needle into the patient. The present invention avoids srch objections since the closure is a permanent non'- breakable valve.
Having thus described my invention, what I claim is:
1. A syringe having a liquid containing body, Said body having an outlet leading therefrom, a member permanently attached to said body and having an outlet passageway, means forming a chamber between said body and said member, a movable valve separate from said body and member and mounted between said parts in'said chamber and adapted to close said outlet and means for adjusting" said member toward and from the liquid containing body to force the valve i against the outlet seat and to release it therefrom.
2. A hypodermic syringe vhaving a. liquid containing body. a hollow needle adjustably attached to said body, a movable closure member between the inner end of the needle and adapted to control the communication between the same and movable into and out of closing position by the adjustment of said needle. s
3. A hypodermic syringe having a liquid containing body, said body havinof an outlet therefrom, a permanent movable valve adapted to close said outlet and an adjustable needle bearing against said valve and operable to force the same into closing position and to releasethe valve to permit the liquid to be forced through the outlet, substantially as described. A
4. A hypodermic syringe having a barrel, a hollow member secured to one end of said barrel, a valve mounted within said hollow member and adapted to close the outlet from said barrel, an adjustable hollow needle having a head projecting within said hollow member and adapted to bear against said valve whereby when said needle is moved inwardly, the valve will be forced to closing position and when the needle is moved outwardly the valve will be released to permit the contents vto be discharged from the barrel into the needle, substantially as described. Y
5. A hypodermic syringe having a liquid containing body, a movable valve for the outlet thereof, an adjustable hollow needle adapted to press against said valve to close the outlet and to release said valve to open the outlet, said needle having means to seal the space around the needle against the escape of liquid when the needle is moved to `releasing position,substantially as described.
6. A hypodermic syringe having a single liquid.ebnta1ning barrel with imperforate walls except for the outer end through which the plunger is inserted and the discharge end Vcontaining the discharge orifice, a plunger in said barrel, a hollow needle attached to said barrel, a movable closure the inner end of the needle and the discharge outlet of the barrel, and means for retaining said movable closure member in closing position against the barrel outlet, said barrel, plunger and closure member being'each formed of aseptic and chemically resistant material, whereby said syrl inge is adapted to serveas a container for www,...
