Specification of Letters Patent. Appuoaon mea my 11, isos. saisi No. 259,973.
. resented au-s1, 1906.v
To all whom, it may concern:
Be it known that we, PATR'IcK J.- MGEL- RoY, lof Cambridge,'in the county of Middlesex, and ,WILLIAM A. RANDALL, of. Swampscott, in the county of Essex, State of Massachusetts, have invented certain new and useful Im rovements in Aseptic Syringes, of which tige following is a specification.
This invention relates to a syringe comprising a barrel and a piston movable therein, both the barrel and the piston being of an aseptic nature, such as glass, which constitutes theentire material ofthe barrel, and glass or other like vitreous material which comprises thebody of the iston, the latter having a packing of suitab e yielding material,y such as asbestos cord, wound uponthe piston. 'In syringes of this character the glass barrel is transparent and is provided with graduating-marks usually. comprising a scale with figures at suitable points to indicate in cooperation with the piston the quantity of lifqid that is discharged rom'the syringe. eretofore, so far as we-are aware,
both the graduated barrel and the body of.'
thel piston have been composed of trans arent glass. The graduating-marks on the arrel are usually formed by an etchin process, the marks being of such character t at when backed bya transparent piston they cannot gie distinctly read and are more or less illegi- Our invention has for its object to enable the graduating-marks on a transparent syringe-barrel to be more lconveniently read than heretofore by the aid of a piston of vitreous material; and to this end it consists in an aseptic syringe comprising a barrel of transparent vitreous material having graduating-marks and a piston of substantially opaque vitreous material forming a background for the said marks and by its contrast with thev transparent material of the barrel making the marks more legible than heretofore. 4
Of the accom anying drawings, forming a part of this specification, Figure 1 represents a longitudinal section of a syringe embodying our invention.v Fig. 2 re resentsa side elevation of the syringe-barre In the drawings, a represents a transparent barrel of an aseptic syringe,` .said barrel bein provided with graduatin -marks b, as usua Said marks are refera ly etched 'on the outer surface of the arrel.
.c represents the body of the piston, which is composed of substantially opaque glass or other vitreous material-that 1s to say, glass whichv is colored or clouded in a pearance, so that it is not transparent. T e color of the bodyis not essential, although a `dark color is preferred. The piston-body is provided With a suitable compressible aseptic packing d, which is` referably formed by windin asbestos corl around the body c. The bo (y c is visible at both ends of the packing, an owing to its opaque character it forms a background for the aduatingmarks on the barrel a, enabling said marks to be quickly and conveniently read, so that the ,operator can readily determine when the pro er quantity of liquid has been ejected.
' he packing, as shown in Fig. 1, is adjacent theinnerendof the lasslunger.j Since said ackin as well t e p unger and the barre, is o such material that the entire syringe can be boiled for sterilization, the device as a whole constitutes an absolutely aseptic syringe. Owing to thefact that the glass `at the inner end of the plunger between the packing and the extreme tip of the er beyond the packing forms a circular n background, and consequently the contrasting background for the graduations will always be present', whether the plunger is rotated more or less within the barrel. Moreover, the ring-like circular background at the inner end of the plunger, bounded bythe eX- treme tip of the plunger and the inner edge of the packing, serves to coperate with t le graduations in indicating to the user the v roper amount of liquid in the barrel regardess of what' the color of such liquid may be.
By the term colored wedo not mean to include such' effect as results `froml (grinding glass, but a distinct color imparte to the glass by some foreign substance incorporated forming a circular Abackground for the gradutherein to produce the desired contrast. ations on the transparent barrel.
