Applicatior lile December 16, 1903. Serial No. 185,386.
To all whom it may concern:
Be it known that I, Frinnnnioii Licitan- HUTH, a citizen of the United States. and a resident of the city of New York, borough. ot Manhattan, in the county and State of New York, have invented a new and Improved Syringe, ot' which the Jr'ollmving is a full, clear, and eX- act description.
This invention relates especially to hypodermic syringes, although certain features ot' my invention could be readily applied to syringes of other types.
The invention iies in certain improvements in the form and construction ot' the syringe, all of which will be fully brought out hereinafter.
This specification is an exact description of one example of my invention, while the claims define the actual scope thereof.
Reference is to be had to the accompanying drawings, forming a part of this specification.l in which similar characters of reference indicate corresponding parts in all the views.
Figure l. is a side elevation or' a syringe with parts broken away. Fig. 2 is a section on the line 2 2 ot Fig. 1. Fig. 3 is a section on the line 3 3 of Fig. 2. Fig. ef is a detail perspective view ot the combined packing and gland. Fig. 5 is a detail section of the hypo-- dermic eedle. Fig. 6 isa section olI the bushing employed in connection with the needle. Fig. 7 is a plan View or' theblank for the linger-piece. Fig. 8 is a plan view of the fingerpiece, and Fig. 9 is a detail view of a niodi'rication in the piston.
Referring to Figs. l to 3, the cylinder r/y is ot' glass and has at one end an integral stuffing-box c and at the other end a nipple (t2, which is provided interiorly with a tapered bore ground true by suitable devices, for a purpose which will hereinafter appear. indicates a glass plunger-rod or piston having at its outer end a ring b for facilitating its operation. rihe interior surfaces ol the cylinder c and the sides ot' the plunger-rod 7J are ground to approximately an accurate engagement; but this engagement is not hermetic, my invention involving means for effecting a hermetic connection between the cylinder and piston at the outer end thereof, and thus avoiding the expense and diiiicnlty of grinding the piston and cylinder mathematically true, as has heretofore been done with a certain class of syringes well known on the market. The-se devices comprise a combined packing and gland c, formed ot' soft rubber and comprising an outer flange lying against the outer end of the smiling-box r1. and an inner cylindrical part .encircling the rod 7). Said inner cylindrical part forms the packing proper and is provided with an annular slit e', which communicates with the interior oi' the cylinder. Now it is clear that when the pressure within the cylinder enters the said annular slit c the packing is spread inward and outward, thus binding' it against the sides ot the piston-rod and also against the sides of the stuhng-box, whereby leakage both through and past the packing is prevented.
The combined gland and packing is held in place byrneans of a cap (Z, ot' metal, hard ruhber, or any desired material, said cap iitting over the rod 7) and being internally threaded. as shown in Fig. 2. These threads of the cap (Z engage the curved tongues d, carried on a. collar e, having the linger-piec.` e2 projected therefrom between the tongues c'. Fig. 7 shows the blank from which the parts c, d, and @i made. This blank is stamped or otherwise produced Vfrom a single sheet or' metal, after which the tongues e are bent up and curved in the are of circle corresponding with the cap (Z and externally threaded. The collar is then drawn over the cylinder and bears against the shoulder formed by the staining-box u", all oi? the parts being drawn snugly together by the action ot the cap and the tongues e', as will be understood.
j" indicates the hy podermic needle.v to which a sleeve 0, preferably olt brass, is soldered or otherwise fastened, as shown, this sleeve encircling one end or the needle and being provided with externally-threaded ends. g indicates a {lange formed on the sleeve to iacilitate turning the same. The threaded sleeve f/ is adapted to screw into a bushing It, which is tted to the bore in the nipple c2. This bushing /i is formed, preferably. ot' hard rubber, and when the parts (j and t are engaged Y together, as shown, the bushing /e/ 1s wedged tightly within ille nipple thus n'niliingi' n.v l
hermetic connection.
