SPECIFICATION forming part of Letters Patent No. 494,048, dated March 21, 1893.

Application led December 9, 1892. Serial No,- 454j684z. (No model.)

To @ZZ whom t may concern:

Be it known t-hat I, JOSHUA MEARUE WAR- DELL, of Cadillac, in the county of Wexford and State of Michigan, have invented a new and Improved Syringe, of which the following is a specification.

My invention consists in certain features of construction of the nozzle and body of a syringe which is particularly adapted and intended for vaginal use.

In the accompanying drawings-Figures l is a central, longitudinal section of the preferred form of my improved syringe, the same being provided with iiexible, watercouducting tubes. Fig. 2 is an end view of the same. Fig. 3 is an enlarged longitudinal section of the nozzle, or delivery end, of the syringe. Fig. 4 is a central longitudinal section of a modified form of my invention.

I will Iirst describe the preferred form of syringe shown in Figs. 1 to 3 inclusive. I preferably make the syringe of hard rubber. The body, A, is tapered and provided with a circumferentialintegral flange, a, at its larger end. The said body, A, has a central longitudinal passage, b, and another but smaller longitudinal passage, c, which is arranged at a slight angle to the other (b), but joins or communicates with it at a point near the smaller end of, the syringe. The smaller passage, b, serves, in practical use, for inlet of water, while the larger central one, b, serves for outlet of the same.

To provide for attachment of a flexible discharge tube B, to the syringe proper, I construct the body A with a nipple d, which is preferably formed integrally with it, While the flexible inlet tube C, is attached to a detachable nipple e. The central outlet passage b, in the body A, is enlarged at the smaller end of the latter, to adapt it to receive the short tube D, which screws into a threaded socket. VThere is an annular space surrounding the body of this tube into which water is received from the inclined passage c and from which it is discharged through the nozzle. The latter is constructed in this wise. The outer end ot the aforesaid tube, D, is liared or provided with a lateral flange f, having an angle of about forty-live degrees. The portion of the body A, which is adjacent and opposite to this flange f, has a corresponding bevel or angle, and is also provided with a series of radial grooves, or kerfs, g, Which serve as so many separate and independent water educts. It Will be understood, that the said llange, f, of the tube, D, fits closely upon the corresponding bevel, f', in which the grooves, g, are formed, so that it constitutesthe inner side of the Water passages. The water being forced through these passages is discharged as independent jets or streams, at an obtuse angle. The most important advantage of this construction of nozzle, is the adaptation of the tube D, for convenient detachment, so that the grooves may be quickly and easily cleaned, (with a brush or other device) in case the)T become clogged by foreign matter. Another advantage is the facility with which the grooves may be molded in the process of manufacturing the syringe. A rubber washer or pad h, is used adjacent to the permanent flange a, in order to prevent escape of water from the'vagina, at any point surrounding the syringe.

In using the instrument, when properlyadj usted in the vagina, water of the required temperature is forced in bymeans of the compressible` bulb t', and discharged in a 8o circle of jets, or streams, from the nozzle. It has free exit from the vagina through the rigid tube D and'lexible outlet tube C.

The syringe shown in Figmt differs from that above described in the following particulars.k First, the body A of the instrument is made hollow to provide an air chamber la la. Second, the outlet passage is formed by along tube,D,which entends entirely through the tapered body. Third, the flexible waterinlet tube B is attached to a cylindrical piece E, which has not only a central longitudinal bore, but also ashort inclined water-inlet passage c. The inner end of this cylindrical piece E, abuts a shoulder formed within the body of the syringe. The long tube, D', is connected with the cylindrical piece, by a screw joint, at its rear end, and the annular water passage formed between the two necessarily extendsforward between the tube and the front end of the body. The chief object of this construction is to provide the afore- IOC its rear end, enlarged in its middle portion, and flared at its front end, and also provided with a series of parallel grooves g as shown, and the detachable outlet tube having its front end dared and provided with a screwthread adapted to engage the thread of said passage, all as shown and described.
