VALVE.

T0 all whomy it may concern:

Be it known that I, ROBERT I. BARNSTEAD, a citizen of the United States, and a resident of Boston, in the county of Suffolk and Commonwealth of Massachusetts, vhave invented certain new and useful Improvements in Valves, of which the following is a full, clear, and eXact specification.

This invention relates to that type of valves for supplying drinking water under ressure, wherein a push valve is connected with laterally extended arms up against which is pressed the cup or glass to be lled, for the purpose of opening the valve and filling such cup or glass. Among other difficulties found to exist in connection with this form of valves is, first, a failure of the valve so to seat itself that the water will be wholly shut od and will not continue to drip; second, when the presser arms are elevated suddenly the delivery of the water is liable t0 be so violent as to spatter itself out from the cup or glass upon the hand or even the cuff of the person operating the same.

The object of this invention is the construction of a valve of the above-named type which shall not only be free of said defects, but shall possess other advantages hereinafter set forth and illustrated in the accompanying drawings, wherein- Figure 1 is a side and sectional elevation of a valve embodying my improvements. Fig. 2 is a top view of the actuating device. Fig. 3 is a horizontal section of the device mainly depended upon for overcoming the violent delivery of the water. Fig. 4 is a Fig. 5 is a face view of a device provided for further assuring against the violent delivery of the water and the consequent spattering thereof.

The reference numeral 1 designates the water pipe supplying the water under pressure of from forty to eighty pounds per square inch, as is found in the city mains, and 2 is the well-known two-armed valveoperating plunger.

The valve proper 3 is made the head of a slender post comprising a neck 4, a shoulder 5, and a body 6 adapted to be screwed into the end of the plunger 2. I have found that the head or valve 3 must be quite small in diameter in order to be raised with sufficient ease against the above-recited heavy waterpressure, for a half inch valve would receive upon its nearly one-fourth of a square inch Specification of Letters Patent.

Application led November 12, 1914. Serial No. 871,830.

of surface a pressure of twenty pounds, in the case of the eighty-pound water-main, and no one could be able to force a cup or glass upward against the valve-arms sufficiently hard to open the valve, without danger of breaking such cup or glass. But, by reducing the valve to a quarter of an inch in diameter, the area is reduced to a sixteenth of a square inch, and the pressure to be overcome is consequently but one-sixteenth of 80, or but five pounds.

The seat for this valve is a Washer 7,tpref erably composed of compressed fiber or hard-rubber, having its central opening 9 somewhat smaller than the valve, but considerably larger than the neck 4, and Iiust large enough to permit the shoulder 5 to easily enter it.

Vhen the post is elevated, as byA an upward pressure applied to the arms 10, the water passes through the opening 9, about the neck 4, and thence downward between the ribs 11 of the plunger 2 into the cup or glass beneath. To prevent the water thus delivered from coming with undue force and thus spraying or spattering itself upon the person holding the drinking glass, I provide means for so hindering the flow as tov give a slow moving but large stream capable of lling the glass quickly but without danger of loss. In accomplishing this, I first provide a tortuous passage formed by a spool whose upper flange 12 is imperforate, but whose lower iiange 13 is formed with numerous holes 14, as is also its tubular body 15 with radial holes 16. When the valve rises above its seat 7, the shoulder 5 enters the interior opening of said spool and so closes all outlets except the tortuous ones through the holes 14 and 16. `While this accomplishes good results where the water-pressure is comparatively low, yet for high-pressure mains, I find it necessary to mount upon the post-body 6 between the shoulder 5 and the top of the plunger 2, a small rotative fan 17, whose vanes 19 are sufficiently twisted to cause their rotation under the action of the water, Fig. 5. Hence, in case the low has not been sufliciently retarded by the spool, this rotating fan effectually brings the same down to the slow speed needed in use.

The washer 7 is held in place upon the top ange 12 within the upper part of the member or valve case 20 by the shoulder 21 which is iXed within the T 22. Vhen the latter member 22 is screwed down within the valve Y the plunger 2.

case 20, the shoulder seats upon the washer 7 and retains it firmly in position.

F or keeping the valve and plunger from rising so high under the glass-iilling pressure that the fan 17 would meet the spoolflange 13 and be kept from rotation, and possibly flattened out, I provide means, as the arch 23 extended radially across the upper part of the Shoulder 21, against which the valve 3 may contact and so limit the rise of the plunger.

Whenever the washer becomes worn and incapable of water-tight engagement with the valve 3, the valve case V2() is unscrewed from the T, the valve post is unscrewed from and withdrawn from the spool, the old washer is removed from the post, a new washer 7 is substituted, and the other parts restored to their original posif tions.

lPrevious to my invention, the plunger V2 was suiiiciently smaller than the interior of the nozzle 24: to permit the unimpeded passage ofthe water, and was without the vertical ribs 11. The diiiculty with such construction was that a strong pressure applied to one alone of the arms 10 was sure eitherl to break or bend the post 6, but by forming the plunger with the ribs 11, as shown in Fig. 2, such breaking and bending is prevented, since the ribs t slidably within the nozzle.

W'hat I claim is:

A valve comprising a casing, a spool therein having radial openings through its body and openings in its lower ange, a valve openingand seat above Said spool, a slender valve opening and cooperating K neck smaller than `the interior of the spool and a body portion tted to enter said interor, put said head out of valve opening.

In testimony thatI claim the foregoing invention, I have hereunto set my hand this 7th day .of November, 1914.v
