JOHN J. HANNIGAN, OF CHICAGO, ILLINOIS.
Specification of Letters Patent. Patented Apr, 26, 191() Application filed March 8, 1909. Serial No. 481,969.
To all whom 'it may concern.'
Beit known that I, JOHN J. HANNIGAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Faucets, of which the following is a specification.
This invention relates to faucets and designs to provide an improved faucet for connection with the ordinary service pipe of a house and so arranged that the valve may be unseated by merely pressing upon a button. p
Another object is to provide a two part faucet, whereby when said valve becomes worn, one section of1 the faucet may be detached from the other (Without shutting olf the water at the base) for the purpose of replacing the worn valve.
Another object is to provide means for preventing the shock or jar caused by the sudden closing of the valve due to the Water pressure.
Another object is to provide a simple form of construct-ion which may be readily assembled or taken apart for repairs.
To such ends this invention consists in certain novel features ofconstruction and arrangement, a description of which will be found in this specification, and the essential features of which will be more definitely pointed out in the claims a pended hereto.
The invention is clearly il ustrated in the drawings furnished herewith, in which* 4 Figure 1 is a central, vertical, longitudinal section througha faucet containing my improvements and showing the same securedI upon the yservice pipe of a buildin Fig. 2 is a similar view with the removab e section removed, Fig. 3 is an end View of the auxiliary valve mechanism, Fig. 4 is an end view of the casing of the removable section, Fi 5 is an end view of a cap, Fig. 6 is an en view of a plunger and showing the valve stem or push rod in cross section, Fig. 7 is a sectional, perspective view of a modified form of cup for the plunger, Fig. 8 is a sectional perspective view of a pneumatic ring which may be used-in connection with the device and Fig. 9 is a side view of a modified form of auxiliary valve.
A, represents the end of a water service pipe, which projects out from the wall, marble slab or the like, B, of the building, and C, represents the faucet as a whole, which as shown contains a threaded nipple 10,
which is screwed into the end of the service pipe A. The faucet is made up of two main casings 11, 12, which are united by a screw threaded connection as seen at 13. This connection is made by formingan externally threaded boss 1&1, upon the casing 12, which is threaded in an internal thread formed upon the end of the casing 11. The easin 12, forms the main body of the faucet and contains a water chamber 12, and the usual spout 15, through which the water escapes therefrom.
The chamber 12, communicates with the chamber 11a, in the casing 11, through a nipple 10, against which seats a valve 17,
preferably formed of rubber or composition and said valve 17, is actuated by a valve stem or push rod 18, which extends out through the end of the casing 12, and bears a button 19, upon its end which is rigidly secured thereto. The valve 17, is mounted upon a reduced end 18, of the push rod 18, and as shown is confined between washers 20, 21, mounted upon the reduced end. The washer 21, bears against the shoulder 22, of the push rod, and the valve and washers are secured .in place thereon by a nut 23, which is screwed upon the screw threaded end of the reduced portion 18a. By pressing inwardly upon the button 19, the valve 17 is forced back from its seat, and water is permitted to enter the 'main chamber 12, and iow out through the spout 15. y
The casing 12, is formed with an internal Hange 24, which is provided with a central opening 25, through which the push rod extends. aud the casing is formed with an externally screw threaded boss 26, which extends beyond the internal flange 24., and provides a chamber 2(3, which is closed at the.
end by a cap 27, that is screwed u on the end of the boss 26. The push ro 18, is .square in lcross section at 28, and the cap 27, is formed with a square aperture 29,through which the square portion of the push rod moves. This arrangement provides means for holding the button in alinement, so that the lettering thereon will be held in an upright position and the stem will be held against turning when the nut 23, is screwed on or unscrewed from the stem. Beyond the squared portion the push rod is provided with a thread 30, upon which is secured a plunger 31, which Works in the chamber 26', of the boss 26, and acts to prevent the jarring ordinarily caused by the pressure of the the inner wall of the chamber 26, thus prothe compressed air does escape around the "an auxiliary valve or shut olf, which auto- (preferably in the form of a metal disk) which is engaged by the push rod 18, when plunger 31, and cap 27. It is evident that by reason its engaginent with the valve stem 37. In
water in the service pipe in closing the valve.` One form of plunger consists in a leather or rubber packing ring 32, which isconned between washers 33, 34, secured upon the screw threaded portion 30, of the valve stem. The packing ring contains an annular flange 35, which fits snugly within vidin'g a compression chamber between the when the push rod is pressed inward, the air space between the plunger and cap is increased in size, which then fillswith air of the leakage around the valve stem at the point Where it passes through the cap. IVhen, however, the push button is released, the water pressure suddenly forces the vvalve 17 back toward its seat, but the air within the air vchamber is compressed, thereby checking the sudden movement of the valve 17 and causing it to close in a comparativelyslow manner, so that the jar or shock is avoided'. Itis vevident that valve stem, but not fast enough to prevent a compression thereof, consequently checking the Vclosing movement of the valve. l
It frequently happens that the valve 17 becomes worn and leakage occurs, and it is necessary to uncouple the casing 12, from the casing 11, and replace the worn valve with a new one. It is often inconvenientto turn the water 0E at the base of supply in order vto remove the faucet, and to overcome this objection, I have provided m` ically closes the entrance to the vcasing 11, when the faucet proper is unscrewed therefrom. As shown the casing 11, is provided with a bridge 36, in which is guided .a longitudinally extending valve stem 37 which bears upon its outer end `a valve 38,
which isl arranged Ito seat upon the end of the screw threaded nipple 10, whenever the faucet proper is removed from the casing 11. The stem 37, is provided with a head 39,
the faucet properis screwed into place and the construction is such that when the faucet is screwed into place the push rod will force the valve 38, from its seat and permit the water to enter the chamber in the casing 11. If desired a spring 40, may be interposed between the bridge 36, and head 39, ofthe stem 37, toassist in closing the valve 38, wheneverwthe push rod 18, is drawn out of the fornir/'shown the valve stem is provided with a .pointed end which seats in a correspondingly shaped socket in the end of the stem 37, thereby assisting in maintaining lwith a hexagon portion 42,
the stein in perfect alinement. The spring 40, not only assists in closing the valve 38, but by reason of the fact that the stem 37 l is in contact with-the stem 18, the spring i holds the valve 17, upon its seat. It is evident that if the push button 19, be pressed,
the valve 17, will be unseated and at the same time the valve 38, will be forced farther away from its seat, thus permitting a free ow of water through the faucet.
-As soon as the push button is released the spring 40, and water pressure partiallyy close the valve 38, close the valve 17 and shutoff the flow of water.' sired to remove the faucet proper, the same is unscrewed from the casing 11, whereupon the spring 40, land water pressure cause the valve stem 37 to follow the push rod 18, as
it is being withdrawn until the Valve seats upon the nipple 10. vThe arrangement ,1s
such that the val-Ve 38, will seat itself prior to the time that the faucet .proper is completely unscrewed from the casing 11.
The stationary section is provided with a hexagon portion 41, which affords means whereby an ordinary wrench may be used to screw said casing in place in the service pipe and the removable section is provided by means of which it may be turned. In Fig. 2 I -have shown a ring 43, which provides a finish between the casing 11 and wall of the building and this ring may be a separate ring or if desired may be cast integral with the casing 11, as desired.
Fi 7 showsa rubber cup 44,' which may be slipped over the valve stem 18, and arranged between the cap 27, and disk 33. The packing ring and backing washer 34, may be omitted, when this cup 1s used, inasmuch as an air chamber will be formed between the cup and washer 33, in which the air is compressed when the valve is forced shut..
In Fig. 8 a tubular rubber ring 45, is
4shown which may be interposed between the cap and washer 33, to provide an air chamber. This ring should contain small perforations 46, to ermita slow escape of air when the ring 1s compressed by the closing .of the valve 17.
In Fig. 9 a ball valve '47, is shown in place of the disk valve 38. It may be found desirable to employ this form of valve in the place of the flat disk.
I realize that more o'r less variation ofthe details of construction is possible without departing from the spirit of my invention, and I do not therefore desire to limit myself to the exact construction shown and described.
