`.TRIPRQVIEHVINTnIN SELF-CLOSING' FAUCETS.

The Schedulereferred to in these Letters Patent andmaking part ofthe same.

lTo all whom it may concern.- y

Be it known that we, CARL ScHULTz and THOMAS WARKER, both of the city, county, and `State of New York, have invented anew and useful Improvement in Self-GlosiugFaucetsfor Mineral-Waters, &'c.'; and

we do hereby declare the following to be a full, clear,

and exactdesc'ription thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, which drawingl represents a longitudinal central section of this invention.

This `invention relates' to a faucet, which is provided with a iiat spring valve, which closes up from the inside against its seat by the combined action of the pressure of l themineral-water or other fiuid, and

by that of a spring, and the stem of which passes through a small openingr and through an expansionchambe'r into a second chamber, which incloses the spring, said spring-being made to act atone end against packing-rings surrounding -the valve-stem,

` and at its other endl againsta head on said valve'- stem, while a screw with a double or triple thread acts against the outside of said head YinA such a manner` that, by turning the screw, the valve is forced off from its seat, and, at the same time, the packing-.rings in the spring-chamber are firmly' compressed against the'stem, and the mineral water or other iuid is allowed to discharge through the expansion-chamber `and spout, without being permitted to `leak past the valvestem into the spring-chamber,L 4and as the liquid passes throughl the expansion-chamber its velocity is reduced in4 proportion to the increase in the area of the transverse section of said chamber over the area of thc transverse section of the opening in the valve-sent, and a large volume of liquid can be discharged with great rapidity, without danger of spilling any portion thereof by the force of the discharge from the tumbler into which it isV received; and 4furthermore, when the hand-screw is released the valve closes automatically, said screw being carried back by the pressure of the liquid against the valve, combined y with the force of the spring.

In the drawingrlhe letter A Vdesignates the head which incloses the valve a. I

Said head is secured by a screw-thread, b, to the tubular shank B, which is intendedto be secured to a mineral-water fountain, or to; another vessel or reservoir containing duid under pressure by a screwthread and nuts, or by any other suitable means.

The inner end `of the head A forms a seat, c, for` the valve a, and this seat is :provided with a hole, through which passes the" stem d of theyalve, said hole beinglf such a size that it leaves sufficient room round the stem to allow the -uid from the fountain or other reservoir to pass out freely to the spout e whenever the valve is forced back from its seat.

` Thespout terminates in lthe expansion-chamheithrough which the valve-stem extends, and which4 rings t', situated at the bottom of the spring-chamber f and embracing the valve-stem, while the outer end of said spring bears against the head j of the valve-stem, and thereby assists in forcing the valve up against its seat.

The valve is opened by a hand-screw, C, which is tapped into a screw-thimble, 7c, secured in the outer end of the head- A, said screw being provided with a hand-wheel and with a double or triple thread, so that a portion of a revolution is sulicient toiopen the valve. far enough for the discharge of the liquid, and that, when the hand-wheel is released, the ,pressure of the liquid acting against the valve, assisted l,joy the force of the spring h, is suiiiciently powerful to carry the screw back to its ,original position, and to close the valveantomatically.

The area of the Vcross-section of the expansionchamher f and that of the cross-section of the spout are considerably larger than that of the annular space left in the valve seat for the discharge' of the liquid when the valve is opened, and as the liquid passes `into the expansion-chamber its velocity is reduced in proportion to such increased area, so that, if the valve is lthrown wide open, the liquid will discharge with great rapidity, and'still sufficiently quiet to prevent any spilling iiom the tumbler into which it is received,

even if the pressure of the liquid is one hundred and twenty pounds to the square inch, while in discharging liquid subjected to such a high pressure through an ordinary faucet the discharge takes place in puffs, and even with the greatest care spilling can hardly be prevented.

With our faucet, therefore, a tumbler can heY filled much more rapidly'than it can with a faucet of the ordinary construction, and the faucetcloses automatically as soon as the hand-screw is released. Y

By the packing-ring or rings i in the bottom of the .spring-chamber the liquid'is prevented..,from leaking
