7 '0 all whom it may concern:

lie it known that I, SAMUEL \V. (iouooN;

a citizen of the United States, rcsidin r at. Newark, in the county of Essex and htate of New Jersey, have invented certain new and useful Improvements in Universal Sterilizing-Stop-Cock Devices; and 1 do hereby.

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 a pertains to make and use the same.

T e invention relates to improvements in stop cocks. 1

The object of the present invention is to improve the construction of stop cocks and to provide a simple, practical, and comparatively inexpensive, universal sterilizing stop cock adapted to control the supply of steam, hot water and cold water and equipped with means for adjustably maintaining the parts in a tight condition and capable of affording read access to the adjusting means when dosire With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out. in the claim hcrctoappended, it being um derstood that various changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing Figure 1 is a sectional view ,of a sterilin ing stop cock constructed in accordance with this invention and shown applied to a sink.

Fig. 2 is an enlarged longitudinal sec-- tional view through a modified form of the sterilizing stop cock.

Like numerals of reference designate corresponding parts in the several views of the drawings. i

In the accompanying drawing in which is illustrated the preferred cmlmdimcnt of the invention, the universal sterilizing stop cock which is designed for use for sterilizing inst rmncnts and analogous purposes comprises in its construction an outer casing l of tubular i'orm tapered forwardly or outwardly and provided at. the top with a steam inlet nipple 2 and having at the bottom ahot water inlet nipple 3 and a cold wate inlet nipple 4. These nipples are shown m the accompanying drawing as formed intcgral with the casing but they may consist of so )arate iieces threaded into the casing. '1 1e nipp e 2 is interiorly threaded for the reception of the threaded end 5 of a steam pipe (5 which may be connected with any suitable source of steam supply. The nipples 3 and 4 are interiorly threaded for the reception of the'threaded ends 7 and 8 of hot water and cold water pipes 9 and 10 connected with any suitable source of supply. Within the casing 1 is arranged the rotary tubular valve 11 provided with ports or openings 12. 13 and 14 adapted to be broughu into register with the nipples 2. 3 and tend 79 as the openings 12, 13 and'H are located at different points around the rotary tubular member two of them will be out of register with their coacting nipples when one is brought into register with it. nipple. By this construction either hot water. cold water or steam may be supplied to the nozzle 15. The rotary tubular member has an outer extcriorly threaded end 16 which is arranged within an enlarged terminal portion 17 of the casing and the said nut is adapted to bear against the coiled spring 18 interposed between the nut and the shoulder 10 formed by the inner end of the enlargement 1?. whereby the spring is adapted to hold tintapcrcd rotary member into tight'engagr ment with the tapered casing to form a waica tight joint or connection between the said parts. Should the tubular member heconr loose the nut is ada )ted to he tightel'ied -3 increase the. tension iii the spring. The llw. which is preferably of octagonal form is a ranged within the extension 17 and the latt is exteriorly threaded at 20 to receive an on lnrgcd cap portioiigl of the nozzle 15. The nozzle 15 by screwing pn the exterior of the enlargement 17 is adapted to be readily removed to afford instant. access to the adjust ing means for maintaining the tubular memher in proper engagement with the casing. 100

5 as required.

- In Fig. 1 is illustrated another form of the invention in which the outer casing 27 is oppositely ta ered from that shown in Fig. 2 and the en arged end is interiorly threaded 10 at 28 for the-reception of a threaded portion 29 of a nozzle 30. In this form of the invention which is simpler than that illus- "trated in Fig; 2 the spring for urging the tapered rotary member into tight engagel; meiit with the casing is omitted.

The nozzle 30 in this form of the intern tion constitutes an adjusting means for maintaining the tapered rotary member in tight engagement with the casing.

\Vhat is claimed is: A valve casin having an inlet 0 )ening, .a core rotatable t erein, having an inlet port and an axial outlet in one end, a nut threaded to the said end of the core, a spring bearing against the nut and casing for establishing a tight. tit between the core and casing and still Jermit free rotation of the Core, a screw threaded extension on one end of said casing and overlying the spring and nut, a spent,

and an internally screw threaded enlargedportion on said spout for connection with the extension.

In testimony whereof I al'lix my signature in presence of two witnesses.
