HYPoD'ERt/nc SYRINGE.
SPECIFICATION folming part of: Letters Patent No. 694,813, datedA March 4, 1902.
Application led August i6, 1900. Serial No. 27,033. (No model.)
T0 @ZZ whom, t lita/ 7j con/cern.' Beitknown that I, BENJAMIN THOMAS WIN- CHESTER, a citizen of the United States, residing at Baltimore city, -in the State of Maryland, have invented certain new and'useful Improvements in Hypodermic Syringes, of which the following is a specication.
My invention relates to improvements in hypoderm'ic syringes which have removable l barrels; and the objects of my improvement are, rst, the construction of a syringe easily taken apart for cleaning; second, simplicity of construction,and,third,cheapness of manufacture. I attain these objects by the mechanism illustrated in the accompanying drawings, in Which- A Figure 1 is a verticalsection of the entire syringe; Fig. 2, a top view of the syringe; Fig. 3, asectional view taken through the barrel and retaining-case at A B; Fig; et, a sectional View through Vthe retaining-case at C D; Fig. 5, View in elevation of the hollow needle and its mountings; Fig. 6, a View in elevation of the retaining-case; and Fig. 7, a sectional view of the syringe, taken at E F.
Similar numerals refer to similar parteY throughout the several views.
1 is the barrel; 2, retaining-case or syringeframe; 3, piston; 4, piston-rod; 5, piston-rod cap; 6, arms of adjusting-yoke; 7, flanged ends of retaining-case 2; S, annular recess into whichriits flanged end 7 of retainingcase 2. v
9 is a pliablegasket; 10, annular flange ad# joining annular recess S; 11, annular iiange adjoining annular recess 8 and forming a backing for pliable gasket 9. Y
12 is a hollow needle; 13, adj listing-yokel and piston-rod guide; 14, annular ange on head of needle; 15, lianged end of retainingcase tube; v16,`annular recess of yoke 18.
17 is ragged end of piston-rod 4; 18, thread-Iy ed portion of yoke 13 for engaging threaded I portion 19 on upper end of barrel 1. y Barrel` 1 may be made of glass, brass, or other suitable material, and has secured toits upper end threaded portion 19, into kwhich* screws threaded portion 18 of adjusting-yoke sembled is to advance barrel 1 against' pliable gasket 9 and head of hollow needle 12, thus making a tight lit. Retaining-case 2 is The object of this When the syringe is asmade out of'metal, such as spring-brass, and
is shaped so that barrel land recesses S and 16 slip into it and are held by spring-contact, it being slightly narrower across its face on account of being slightly more than a semicircle in cross-section.
2. In a syringe, the combination of, a retaining-case made of spring material which is slightly narrower across its face on account of` being slightly more than a semicircle in cross-section thereby enabling parts placed therein of substantially the same diameter being yheld thereby, a barrel with its necessary operating piston and mechanism for Y working the same secured in said case, abel-p low needle secured by a flange to one end of said case and adjusting mechanism` secured by a flange at other end of said case and means for bringing the various parts together so that they may be made tight at their joints when the said barrel is in communication with said hollow needle.
' In asyringe, a hollow needle detachably secured to the case of said syringe by means of a liange on one end of said case which an'geits into a groove on the head ot said needle, a Ybarrel secured in contact With the headof said needle by pressure longitudinally appliedfan adj listing-yoke secured in v, said case by mea-ns oa flange on end of said case fitting into a groove in the said adjusting-yoke voperating to force the said barrel 'against the head of the said hollovsr needle,
and a piston operated in said barrel by means roc of a piston-rod attached thereto operating I ease made of spring material which is slightly through said adjusting-yoke.
4f. In combination, in a syringe, a barrel, a piston operating therein, means for operating the piston, a hollow needle, and a retainingcase made of spring material which is slightly narrower across its face on account of being slightly more than a semicircle in cross-sec- Lion.
5. In combination, in a syringe, a barrel, a piston operating therein, means for operating the piston, a hollow needle, a retainingnarrower across its face 0n account of being slightly more than a semicircle in cross-secx3 tion, said case being ianged for securing said hollow needle at one end and for securing an adjusting mechanism at the other end and means for securing the Various parts.
