To ALL WHo-M IT MAY ooNonnN:

Y Be it known tha-tl, MATTHEW FALOON, M. D., of l 3loon1ington, in 4the county ofMcLean, Aand inA the'Srtate of Illinois, have invented certain new andnseful Imp-ro'vementsin Syringes; and do hereby declare that' the following is a. full, clear, and exactdescription thereof, reference being had to the accompanying drawings, andY the letters of reference marked thereon. v v

In 'the annexed drawings, making agpart of tbisspecicati'on, A represents an elastic rubber bulb or globe, and `.provided with a shoulder,z,'near the-monili` or openingv thereof, and B represents the permanent nozzle, oneiend of it, which goes into the bulb A, beuelled oi, as shown, and provided with a barb-shoulder, c, whichd catchesagainstand behind 4the shoulder a; of the elastic bulb A. The other end of the nozzleB has ascrewthread cnt onitsoutside, which fits in 'and secures the adjustable nozzle C. The screw-thread is made onthe permanent piece B,'for the pirrpose'ofcondueting the liquid to be ejected past the joint in a smooth and 'regular channel, and thereby prevent theylealiage caused-bythe ordinary construction. The screw-threadie-usuallyv .made on ythe adjustable nozzlerC, which is then screwedinto the Permanent piece B, thereby presenting its end -as an obstruction in thepassage, and `thereby causes all nozzles made in that wayV te leak more or less, unless screwed up very hard againstthe washer in ordinary use, in'whichcase the nozzle C becomes fast, and cannot b e taken o'to'allow anotherrof different shapeto be adjusted. Y

The adjustable nozzle may be of any shape that maybe required. Both the piece B and vnozzle, C are best made of hard rubber, as not liable to coi-rode by the use ofany liquid medicine.

The above malres'an'iinprored cheap and convenient syringe, Afor injecting medicine or liquids of'any kind to any part'of theihu'man body, or elsewhere, as may bedesircd. I do not claim the single b ulb A; nor do I claim connecting the nozzle to the part B by a. male and female screw. My application consists in the combination ot" the interior part B, made of hardrubber, and for use in the manner described. i l

what I claim is l VThe piece B, made convexon its iriner end, forming a shoulder, a', und provided with a ange on the outer part, which cov'ers` the neck of the bulbA A, when arranged and used substantially as specified. v l In testimony that I claim the foregoing, I have hereunto set my hand, this 3d day of January, 1868.
