FLUID-MIXING FIXTURE.

SPECIFICATION forming part of Letters Patent No. 659,260, dated October 9, 1900.

' Appnmion tied May 3, 1900. serial No. 15,324. (No man.)

To a/ZZ whom it may concern:

Be it known .that I, ALFRED A. SCHRATZ, a citizen of' the United States, residing` at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Fluid-Mixing Fixtures; and I declare the following to be a full, clear, and exact description of the same, suchas will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to a fixture for mixing a disinfecting iiuid with water, and has for its object an improved fixture intended to be used in places where itis desired to employ an antseptic wash-water; and the purpose of the invention is to produce a fixture which will mingle an antiseptic iiuid with a stream of water iiowing from any source of supply.

In 'the drawings, Figure l is a vertical elevation, partly in section. Fig. 2 is a drawing, most-ly in section, and shows the parts as they appear on a plane passing diametrically and vertically through the fixture and at right angles to the plane ofthe section shown in Fig. l.

1 indicates the stem, which is arranged to be secured to afable-top by a spindle la, screwthreaded at its end, adapted to be passed through the table-top and to have a nut lb run onto the threaded part of the spindle. The fixture is provided with a chamber 2, into which lead water-pipes 2iL and 2b, one ofthe inleading water-pipes being intended for warm water and the other for cold water, each leading from an independent source of' supply, as from a water-main and a boiler. Each water-main is provided with its individual cutoff valve 2C and 2d. From the bottomv of the chamber a passage 2e leads out to a faucet 2f. From the upper end of the chamber 2 a passage 2g leads upward to a valve 3. Between the outlet 2g and the valve 3 there is a checkvalve 3, seating downward and adapted to be opened by the fiow of liquid from the chamber 2. Above the check-valve 3a is an adjusting-nozzle 3b, which limits the opening movement of the check-valve and which may be adjusted by changing its vertical position with reference to the check-valve. The adjustment is effected by making the nozzle as a screw-nipple and engaging it in the hollow screw 3C, which forms the upper part of the fixture just below the casing of the valve 3. A valve-casing 4 is located just above the parts previously described and is fitted with a three-way plug-valve 3. The passage leading from the chamber 2 leads into the chamber of the valve-casing 4, and a second passage 4 leads vertically downward into the same chamber from a higher part of the fixture. On the upperend of the fixture is mounted a tank 5, the outlet of which is engaged in the fixture and the passage through the outlet of which c'ommunicates with the passage 4a, and through the passage 4a it communicates with a passage 3d in the plug-valve. In the passage 4a, between the tank and the upper portion of the casing 4, is inserted apressure-reducing nipple 6, which is removable from the fixture. The nipple 6 is provided with a flange 6a, that rests on an annular shoulder 4b in the fixture. The nipple is provided with a hollow stem-like projection perforated with small holes 6b, which constitute communicating passages through the nipples between the tank and the casting, and a nipple with holes of proper size with reference to the head of the water and with reference to the size of the tank 5 may always be used--as, for example, if the tank 5 be large, so that there will be a considerable head of liquid in it, a nipple with small perforations 6b may be selected and the outflow of liquid limited, and this limitation may be made with reference tothe normal flow of water through the pipes 2a and 2. Such regulation need only be made once for the same instrument, and it is consequently not necessary to make this part adjustable, as the single adjustment of the nozzle 3b will suffice to regulate with sufficient accuracy the mingling of the water with the antiseptic. The plug-valve 3 is turned by a handle 7 to bring the passage 3e and the passage 3d into position to permit the iiow of water from the passage 2g through the passage 3e to the outflownozzle 8 and at the same time to permit the flow of the antiseptic liquid through the passage Sd into the passage 3e. When thus arranged, the mingling water and antiseptic are delivered from the nozzle 8. Clearwater may be drawn from the nozzle 2f. Generally when clear Water is drawn the valve 3 is turned to prevent the passage through it of either water or antiseptic; but even if it be not turned the check-valve 3 prevents the` return flow of water through vthe passage 21W and prevents the entrance of any antiseptic into the chamber 2.

What I claim is- 1. In a xturefor mingling antisepticfluid With water, in combination with a standard provided with an i'nfio'W-pipe -for water and a nozzle for the. delivery of ythe-same, an afntii septic-tank connected with the fixture, a three-way valve adapted to allow the fiow therethrough of both Water and the antiseptic liquid, a nozzle for the delivery of the Vln-ingled liquids, and a check-valve in the xture. between the inow-pipe for water and the the inflow-'pipe for water, and the three-way valve, and a regulating-nipple adjustable with respect to thecheck-valve, and adapted to determine the amount to which the checkvaflve opens, substantially as described.

In testimony whereof I sign this specification in the presence of two Witnesses.
