` CINCINNATI, OHIO, .A CORPORATION OF OHIO SELF-CLOSING FAUCET.

Specification of Letters Patent. Patented June 6; 1922.

- Application filed April 19, 1919. serial No. 291,316.

To all whom t may concern.'

Beit known that I, JOHN MGNEIL, a' citlzen of the United States of America, yand a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Self-Closing Faucets, of which the -following is a specification;

An object of my invention 1s to produce an improved faucet which is particularlyl adapted to be used in lavatories, whlch 1s of the self-closing type, and which will prevent water-hammer occurring in the closing operation.

A further object is to produce a lavatory faucet which is of the self-closing type and in which uniformity of closing action is had regardless of the amount of suspended sediment or the corrosive action of the water passing therethrough.

These and other objectsare attained in the faucet described in the following specification and illustrated in the accompanying drawings, in which- F ig. 1, is a sectional view of a faucet embodying my invention, showing the elements thereof in closed position.

Fig. 2, is a sectional elevation of a faucet embodying my invention, showing the elements thereof in open. position.

Fig. 3, is a sectional fragmental view of a detail of the faucet embodying my invention.

My improved faucet has a casing'l, at the lower end of which a nipple 2 is provided for admitting water thereto, a discharge nozzle 3 being located at the upper end of the casing. A handle 4 is provided, which is held in position by housing 5, located above the casing. A member 6, which is screwed within the upper end ofthe easing, contains the valve yseat 7 which is preferably of some suitable compressive material, this member being also used to secure housing 5 at its upper end. A cap 8 is reciprocally mounted Within the housing 5, and is held against the lower end of handle 4 by means of a 'spring 9 which bears at its lower end against member 6. This holds the handle in the position shown in Fig. 1, and permits it to be returned to this position after having been moved to faucet opening position, as shown in Fig. 2. A valve stem 10, which carries valve 11 at its lower end, is held against the inner surface of cap 8 by means of a spring 12, which bears at itsupper end against an adjustment nut 13, mounted upon the valve stem and at its lower end agalnst the packing 14 which is located within member 6. Beneath the packing 14 a passage 15, which communicates with the lower chamber of the casing, is provided, this passage being provided with ports 16, which communicate wlth a chamber 17 froml which the discharge nozzle 3 extends. At the lower end of valve 11 a packed plunger 18 is provided, which is -reciprocally mounted within acup 19, in the 1nlet passage and at the upper end of nipple 2. A pointed pin 2O is located within a passage 21, within the plunger, the passage terminating at its bottom in a port 22 and at its upper end in a chamber 23, which is provided witha port 24 communicating with the lower chamber 25 lof the casing. Ports 26 are located beneath cup or cylinder 19 and connect the interior of nipple 2 with chamber 25 of the casing.

In opening my improved faucet for a discharge of waterfthrough nozzle 3, handle 4 is tilted to the position shown in Fig. 2.

This presses upon cap 8, and therefore upon stem 10 of the valve, compressing springs 9 and 12, thus forcing valve 11 to move away from seat 7 and open the direct passage from the water supply through ports 26, chamber` 25, passage 15, port 16, chamber 17 and nozzle 3. Simultaneously with the action of the valve the movement of plunger 18 downwardly within cylinder 19, will cause pin 20 to rise and permit the passage of water through passage 21 and. port 24 and thence to be discharged through the faucet. When this water has been discharged pin 2O will drop back to its normal position closing port 22 and when handle 4 is released water will pass through the chamber 25 aroundthe packing in plunger 18 and gradually back into the lower portion of cup 19 and permit the springs 9 and 12 torestore the parts of the faucet to normal condition, thus bringing the valve back into engagement with valve seat 7. The faucet thus gradually closes itself and prevents water-hammer by having the water gradually closed off.

An advantage of my invention over other previous inventions known to me is that the pin 2O moves at each operation of the water, thus clearing the passage 21 of any sediment or corrosion, and also maintaining a clear port 22. There can therefore be no hesitancy lll@ or refusal of the faucet to act properly even after long periods of use thereof.

Having thus described my invention what I claim is 1. A faucet comprising a casing having inlet and discharge passa es, a cup having an imperforate bottom an being in the inlet passage. and in axial .alignment with the casing, avalve in the casin ,-a valve plunger at the lower end of the va ve and enga g the inner walls of the cup,`said plunger aving an internal passage and a port at the lower end of the passage forming communication between the passage andthe inside of the cup, and a port at the upper end of the passage forming communication with i the l inlet passage, a pin located within the pasagainst the wall surrounding the port in thev sage in the plunger, and adapted to seat bottom thereof.

2. A faucet comprising a casing having inlet and discharge passages, a cup having an imperforate bottom and being in the inlet passage and in axial alignment with the casing, a housing having an open top and a re-entrant annular flange mounted above the casing, a reciprocating cap within the housing, a valve in the casing, a valve stem extending into the housing, and adapted.-

to engage one side of the cap, a valve plum upon its seat.

ger at the lower end of the valve and engaging the inner wall of the cup, said plunger having an internal passage and a port` at the lower end of the passage forming communication between the passage and the` inside of the cup, and a port at the upper end' of the passage forming communication ywith the inlet passage, a pin' located within the passage in the plunger adapted to seat against the wall surrounding the port Vin the bottom thereof, a handle having at lts lower end a substantiallyl flat and circular disc adapted to engage on its lnner surface with l In testimon whereof, I have hereunto subscribed my name this 16th day of April,

JOHN MONEIL.
