SYRINGE.

SPECIFICATION forming part of Letters Patent No. 321,850, dated July 7, 1885.

Applicationiiled April 30, 1885.

To LZZ whom, it may concern:

Be it known that I, GEORGE E. PHILBRICK, a citizen of the United States, residing at Manchester, in the county of Hillsborough and State of New Hampshire, have invented certain new and useful Improvements in Syringes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form apart of this speciication.

This invention relates to improvements in vaginal syringes; and it consists in the construction and combination of the several parts hereinafter fully described, and pointed out in the claims.

In the drawings, Figure l is a plan or top view of the back receiving-reservoir. Eig. 2 shows a view of the cushion. Fig. 3shows the two-part inlet-pipe. Fig. 4 shows a side view and a sectional view of the flanged washer; and Fig. 5 is the complete syringe, having the reservoir, the inlet-pipe, and the spray-tube in section.

a is the back receiving-reservoir,made preferably of non-corrosive metal or hard rubber, and made funnel-shaped, and provided with a nipple,a,surrounding the exitopening,adapt ed to receive the end of the discharge-tube b. The nipple may be constructed, as shown, so that the iiexible rubber tube can be sprung on it; or it may be provided with ascrew-thread to receive a correspondingly-threaded couplerring held in the end of the pipe b. The reservoir is made funnel-shaped, so as to present no angular surfaces to catch and retain any mucus or other material carried in the outiowing water. An annular cushion, c, of soft rubber or other suitable material, is placed on the upper edge of the reservoir. Itis formed with an inwardly-projecting shoulder, c, which extends over and rests upon the upper edge ofthe reservoir. It also has the depending iiap or wing c2, which is made tapered or funnel-shaped in form, corresponding to the shape of the reservoir. The wing o2 is sprung over the upper end of the reservoir, and,by reason of its shape, holds the cushion firmly in place and draws the shoulder c firmly against the said upper (No model.)

edge. The inner face of the cushion is tapered the inner side 0f the reservoir. It is preferably tapered so as to makeits upper edge thin, as shown, so as to increase its elasticity and permit it more readily to conform to the locality against which it is pressed. ln order to prevent the cushion from being displaced when too great pressure is exerted upon it,a small annular flange, a2, isformed around and near the upper end of the reservoir. The wing of the cushion draws down against this flange, but is prevented thereby from being forced any farther.

Near the lower end, and at one end of the axis of the oval reservoir, au opening, a3, is formed to receive the inl et-pipe. The arrangement of the opening aa on the longer axis ofthe oval reservoir is for the purposes apparent to any one acquainted with the use of syringes of the class to which this invention belongs. The inlet-pipe d is composed of the inner tube, d', and the outer tube, d'2. The inner tube has a suitably-threaded end to receive the spray tube or nozzle e,whereby the latter may be attached or detached at pleasure. It is made in a gradual curve, as shown, so that its outer end will project through the opening a3 and its inner end stand at or near the center of the` reservoir. Its upper end is arranged just below the plane of the upper edge of the reservoir, so that the spray tube or nozzle may be readily attached thereto. It is made preferably in the arc of acircle, so that it may readily be inserted through the opening a3. It has a circumferential flange, d3, arranged to fit snugly against the inner side of the reservoir and make a water-tight joint. Its end projects to the outer side, and is provided with threads to receive the correspondingly-threaded socket on the end of the outer tube, d2. On the projecting end of the tube d atapered washer, d4, is placed, as shown, which is adapted to fit snugly against the outer side of the reservoir and make a water-tight joint; or,in place of the washer, a boss may be made on the outside of reservoir. The end of the outer tube, d2, jams against the outer side of the washer or boss, as shown. The washer, when used, is provided with an annular rim-1iange, d5, in order to give it greater bearing-surface and thereby If desired, a gasket, d5,

make a better joint.

\ to correspond approximately with the taper of IOO of rubber or other suitable material, may be placed between the Washer or boss andthe reservoir, in order to make a more perfeet joint or to close small leaks consequent upon imperfeet Construction of the Opening` a and piped. To the pipe or tube di the end of the supplypipef, with its bulbf, is atttaehed, as shown.

The manner of using` the syringeis obvious, and need not be explained at length.

The results secured by thissyringeare, iiret, perfect cleanliness; second, freedom from leal;- age; third, ease with which it may be applied and heldin place; the projecting end of the pipe affords support for one or more of the iingers, while the other iinoers may be clasped around the lower smaller end of thereservoir; fourth, the eoaptation is sneh that it can be used in a standing, sitting, or reclining position; fifth, the several parts maybe easil y separated for packing or other desired purpose, and be as easily and quickly put together.

Having thus described my inventioinn'hat I claim, and desire to secure by Letters Patent, 1s-

1. The eonibinatio1i,with the funnel-Shaped back rceeivingreservoir, of the inner curved pipe, d, pipe provided with annular flanges di, the outer pipe, di, threaded onto the outer projeeting end ofthe pipe df, and the tapered washer or boss d, substantially as set forth.

2. The cornbinationgvith the fnnnel-sl1aped or tapered back reeeivingaeservoir, of the annular cushion provided with an inwardly-liniejeeted shoulder covering,` the upper edge of the reservoir and having the depending annular tapered flap or wing to be sprung over the outer side oi'lhe upper end of the said reservoir, and the annular sustainingring ai, projecting from the reservoir, substantially as set forth.

In testimony whereof I ai'iix my signature in 4o presence of two Witnesses.

GEORGE EDW'IN PHILERTCK.
