Specification of Letters Patent.

To all whom it may concern:

Be it known that l, CHARLES B. l/Vi-IITNEY, a citizen of the United States, residing at Hyde Park, in the county of Norfolk and State of Massachusetts, have invented new and useful Improvements in `Faucets, of which the following is a specification.

This invention relates to improvements in faucets and ball cocks, the object of the invention being to provide a faucet or ball oock which is closed by the pressure of the water and in such a manner as to do away with the shock or jarring known as water hammer.

The object is further to provide a device of the character referred to in which the valve is closed in such a manner that it will be sure to find its own seat thus preventing any tendency to leak, the valve being provided with a stem which extends longitudinally upon opposite sides of the valve disk and is operated by certain means or mechanism hereinafter fully described which means or mechanism bears against the opposite ends of said stem, the valve thus being suspended as it were between two points and only guided in its longitudinal movement from extreme lateral displacement.

The object of the invention is still further to so connect the lever by which the faucet is opened that the easing may be swiveled .relatively thereto to any desired position aecording to the location of the faucet or according to the desire of the person operating the faucet.

T he invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings: Figure 1 is a central longitudinal section, partly in elevation, of a faucet embodying my invention. Fig. 2 is a section, partly in plan, taken on line 2-2 Fig. 1. Fig. 3 is an enlarged central longitudinal section partly in elevation of the plunger. Fig. 3a is an enlarged side elevation of a modified form of plunger. Fig. 4L is an enlarged section of the disk and its locking nut attached to the valve stem, said valve stem being shown in elevation. Fig. 5 is a longitudinal section, partly in elevation, illustrating my invention applied to a ball cock for a closet tank, the ball cock lever being broken to save space.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, referring to Figs. 1 to 4, inclusive, 8 is the casing of a faucet consisting of a body portion 9 having a spout 10, a base 11, and a cap 36. The base 11 is adapted to be fastened to a bowl and is formed in the usual manner having a tubular shank 13 which projects through the fixture to which the faucet is to be attached and has a flange 141 at its end, said shank being screw-threaded at its lower end in order that it may be clamped by suitable nuts to the fixture to which it is attached. The base 11 is attached by screw-threaded engagement therewith to the body portion 8 and has in the interior thereof an inlet passage 15 into which an annular flange 16 projects. The body portion 9 is also provided with an annular flange which forms a seat 17 for the valve 18. The valve 18 consists of a stem .19 which has attached thereto a disk 2O provided with a washer 21 located in a cylindrical recess formed in the upper face of said disk.

The disk 2O has screw-threaded engagement with the stem 19 and bears upon its upper faee against a flange 22 integral with the stem 19, said disk is pressed against the flange 22 and held locked upon the stem 19 by means of a nut 23. The lower end of the stem 19 bears against the to of a plunger 24 adapted to slide longitudinally thereof in the inlet passage 15. Said plunger is preferably constructed of a tube 25 closed at its lower end as seen in Fig. 3, and provided with slots 26 extending longitudinally thereof. The upper end of the tube 25 has an inverted cup-shaped head 27 provided with perforations 28.

In its operation the head of the plunger 24 has sliding contact with the walls of the inlet passage 15 and the tubular shank 25 slides in Contact with the annular flange 16. A spiral spring 29 encircles the tubular shank 25, one end bearing against the head 27 and the other end thereof bearing against the annular flange 16. The valve 18 is moved away from its seat by means of a lever 30 and pin 31. The pin 31 has an annular flange 32 thereon, which slides in a cylindrical recess 33 formed in the top ofthe body portion 9 of the casing. The upper end of the pin 31 bears against the underside of the lever 30, said lever being provided with a pivot 34. which extends laterally therethrough and into a holder 35, which is inclosed Within the cap 36.

The holder 35 is slotted at 37 and the cap 36 is slotted at 38 to receive the lever 3() and to allow said lever to rock upon its pivot. The cap 36 has an annular flange 39 upon the bottom thereof which projects beneath a similar flange 40 formed upon a sleeve 41 which has screw-threaded engagement with the top of the body portion 9 of the casing. The sleeve 41 at its lower edge bears against the shoulder 42 formed upon the body portion 9, said shoulder being so located that when the sleeve 41 is screwed down firmly thereagainst the cap 36 will be held against the top of the body portion of the casing, but will be free to rotate thereon, sc that the lever 30 can be rotated with said cap and with the holder 35 to any desired position relatively to the casing, thus adapting the lever to be placed in different positions as may suit the convenience of the user or as may suit the requirements of the faucet when placed in different positions.

The stem 19 is preferably rounded at the top and bottom thereof so that it bears against the lower end of the pin v31 and against the ulpper end of the plunger 24 upon a very smal area. The disk 20 is guided against-any extended lateral displacement by guide ribs 42 integral with the casing body 9 and projecting inwardly from said casing toward the center of the stem 19. There is, however, a slight space between the periphery of the disk 2() and these ribs 42 which allows the valve to move freely and also allows the disk'to seek its own seat upon the valve seat 17, thus preventing any leakage.

In Fig. 1 the lever 30 is shown depressed, the valve being opened and the flange 32 upon the pin 31 pressing against the bottom of the recess 33, this flange thus prevents any leakage around the lever 30 and cap 36 due to back pressure of the water when the valve is opened. The interior of the body portion of the casing above the valve seat constitutes an outlet chamber 43, the interior of the body portion of said valve below the valve seat constitutes an inlet chamber 44, into which the inlet passage 15 opens.

The slots 26 in the tube 25 are so located that when the valve is closed said slots terminate above the lower edge of the annular flange 16, and when the valve is open said slots project downwardly below said annular flange.

Having thus specifically described my invention, bI will now proceed lto describe the operation thereof having still reference to Figs. 1 to 4, inclusive. Assuming the valve to be open as illustrated in Fig. 1, the water will enter through the inlet passage 15 in the direction of the arrow a, Fig. 1, and will pass through the slots 26 into the interior vof the plunger 25 and lcompletely fill the inlet passage 15. Pressing the flange 27 upwardly against the bottom end of the stem 19, the

water will flow through the perforations 2S and into the inlet chamber 44, from this it will pass through the space between the valve disk and valve seat into the outlet chamber 43 thence flowing outward through the spout 10. Upon releasing the lever 30 the pressure of the water will close the valve by pressing upwardly upon the plunger until the disk 20 comes to a seat upon the valve seat 17. During the latter portion of the upward movement of the plunger, the slots 26 move upwardly until the bottoms of said slots are located above the bottom of the annular flange 16 and the water is thus gradually shut ofl from direct connection with the valve, but will still press against the bottom of the plunger and hold the same firmly against the lower end of the stem of the valve, whereby said valve is kept against the seat.

is to assist the operation of the device in preventing a rebound or )ar-ring of the valve after it has come to a bearing upon its seat, but the gradual shutting off of the water by the slotted plunger 26 is the principal cause in this device of the elimination of such jarring or hammering known as the water hammer' lt will be understood that the plunger 24 is preferably a differential plunger, that is, the area of the head minus the area of the perforations therein is greater than the area of the lower end of the shank, so that when the valve is open as in Fig. 1 and the pressure upon the lever 30 is removed, the force of the water tending to close the valve in so far as the upward pressure upon the under side of the head is concerned, is greater than the pressure of the water downwardly upon said plunger against the upper or inner face of the bottom thereof, but not so great as would be the case if the plunger were not a differential plunger. In other words, the area of the under side of the head 27 minus the area of the perforations therein and minus the area of the upper face of the bottom of the plunger 24 is greater than the area of the lower face of the bottom of said plunger. Therefore, the pressure on the lower face of the plunger 24 plus the pressure on the under side of the head 27 is greater than the pressure on the upper side of the lower end of said plunger. Consequently, the plunger 24 moves upwardly assisted by the spring 29, but the lower ends of the slot 26 almost immediately pass beyond the bottom of the annular flange 16, thereby shutting off the supply of water from the inlet passage 15 to the pasl sages above the annular flange 16. Pressure now exists only on the lower face of the lower end of the plunger' 24. The pressure on the lower face of the bottom of the plunger 24 assisted by the spring 29 still continues to move the plunger upwardly, but water,

The function performed by the spring 29 course, remains in the inlet chamber 44 and l ential plunger adapted to slide in said inlet in the outlet chamber 43. As the plunger 24 continues to move upwardly, the space between the head 27 and the flange 16 increases and, therefore, continued upward movement of the plunger 24 tends to produce a vacuum in the space between said head and said flange and, therefore, a portion of the water contained in the chamber 44 is compelled to flow downwardly through the perforations 28 and outwardly through the slots 26 into the space surrounding the tube 25. This tendency to form a vacuum between the head 27 and the annular flange 16 obviously checks the upward movement of the plunger 24 and its speed is limited by the speed of the water which flows downwardly through the perforations 28 through the slots 26 and into the space between the head 27 and flange 16. Therefore, after the lower ends of the slots 26 have passed upwardly beyond the under side of the flange 16, the upward movement of the plunger 24 and disk 2() is very slow and said disk is moved into contact with its seat 17 very gently without rebound or hammering. lf desired, the plunger may be made with the slots 26/ of different lengths or with their lower ends terminating at different distances from the bottom of the plunger as illustrated in Fig. 3a.

In Fig. 5 l have illustrated a modified form of my invention adapted to be used as a ball cock in which the principle of operation is the same as that described in Figs. 1 to 4, inclusive, except that the lever 30 of the form hereinbefore described is replaced by a lever 30 which is a ball cock lever and is supported upon a pivot 34 fast to ears 45 formed upon the casing 8. The lever' 30 has a cam-shaped or eccentric-shaped disk 46 integral therewith which bears against one end of the pin 31. The casing 8 consists of a body portion Q having a spout 10 and a base 11. The valve 18 consists of a stem 19 and a disk 20/ which is adapted to bear against the seat 17 formed in the casing. The plunger 24 bears against one end of the valve stem 19 and is encircled by a spring 29. similar to the action of the form of my invention which l have described and illustrated in Figs. 1 to 4, inclusive, in so far as the operation of the pin 31, valve 1S', and plunger 24/ is concerned.
