Specification of Letters Patent. l

Patented NOV. 1S, 1919.

Application filed. March 6, 1919. Serial No. 280,954.

To all whom t may concern:

Be it known that we, GEORGE F. MOCULLY and AUGUSTUS ALEXANDER DAvmsoN, both subjects of the King of Great Britain, and residents, respectively, in the cities of North Vancouver and Vancouver, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Faucets, of which the following is a speciiication. y

Uurinvention relates to improvementsin faucets, and the object of our invention is to Figure 1 is an outside View of the faucet.`

Fig. 2 is an lenlarged vertical longitudinal section, taken on the center line.

Fig. 3 is a sectional elevation of the upper part of the faucet, showing the operating spindle.

Fig. 4 is a detail view of the operating spindle.

Fig. 5 is a plan view of the removable valve seat.

Similar figures of reference indicate similar parts throughout the several views.

1 indicates the base portion of the faucet, which is provided with a threaded nipple .2, the bore of which is restricted as at 3, by means of which nipple the faucet is adapted to be connected to a water conduit. The base portion is exteriorly threaded as at fi to receive thereon the upper part 5 of the faucet, which is correspondingly threaded interiorly at its lower end, as at 50, this upper part being provided with a transverse wall 6 having an opening 7, as shown in Fig. 2, which wall separates the chamber 8 of the upper part 5 from the chamber 9 of the lower or base part 1, this latter chamber being in communication with the bore 10 of the nipple 2 through the restricted opening 3, as hereinafter more fully described, while the chamber 8 is in communication withthe delivery spoutll, secured into the side"of the upper part in any approved fashion. The bore of the chamber 9 is undercut, as indicated at 12 in F ig. 2, so that annular upper and lower bearing strips 13 and 111 are formed adjacent the upper and lower ends respectively of the chamber 9, from which it will be seen that when the liner 15 is fitted into place an annular chamber 16 is formed extending around the liner. The lower end of the liner rests on the bottom of chamber 9 and at a suitable height in the liner wall an aperture 17 is provided, as many of these apertures, however, being provided as arc deemed necessary, while adjacent the bottom of the liner in the side thereof is formed an aperture 17a, as shown in Fig. 2.

Slidably mounted for vertical movement in the liner 15 is a hollow plunger 18, open at its upper end, its lower end being closed and provided with a restricted aperture 19, as shown in Fig. 2, which plunger is provided with a groove 20 ruiming annularly therearound on the outside thereof adjacent its upper end, an aperture or port 21 being provided through the plunger wall and positio-ned in the groove 20, all shown in Fig, 2. The number of these ports 21 may correspond to the number of apertures or ports 17 in the liner. This plunger is mounted on the lower end of the valve member 22, an extension 23 on the valve member fitting an opening 24 in the closed end of the plunger, which extension projects beyond the plunger end and is fitted with a nut 2l L by means of which the valve member and plunger are held together. The nut 23a rests on the bottom of the liner 15 when the valve member is depressed so that a space 211 is formed between the bottom of the liner and the bottom of the plunger, which space communicates with the annular chamber 16 through the aperture 17L hereinbefore mentioned. cylindrical, of less diameter than the bore of the plunger 18, and its upper end is mitered or rounded to form a valve head 25. Up to this point the construction described is substantially the same as that described in the Canadian patent hereinbefore mentioned, according to which construction the opening 7 of the transverse wall 6 was mitered to form a valve seat cosacting with the mitered end of the valve member 22, these numerals having reference to the present specification. According to the improved The lvalve member 22 is formed construction forming the subject matter of in place, the upper face of the disk being flush with the upper-end of the -base portion so that the upper part 5. may be screwed down on to the lower part to carry the wall 6 against the disk 26 and hold it in position. The disk is provided with a boss 27 extending upwardly through the opening 7 of the wall 6, through which boss extends a bore 28 widened at its lower end and shaped to form a valve seat 29 adapted to co-act with the upper end of the valve member 22, that is,the valve head 25, while extending upwardly through the bore 28 to project a suitable distance beyond the upper end of the boss 27 is the valve member operating stem 30, which stem is secured to the upper end ofthe valvemember in any suitable manner. This stem is reduced for a portion of its length, as indicated at 31 in Fig. 2, in order to permit water to flow therearound and out through an aperture 32 in the boss 27 when thev valve member 22 and plunger 18 are depressed.

A further improvement in the original construction described in Canadian Patent No. 169,712resides in the arrangement for depressing the valve member 22. In that construction the operating stem extended straight up through the upper part of' the faucet and then slidably through a packing nut on the faucet upper end, being threaded to receive a push button. It is found preferable, however, to form a transverse cylindrical member 33 on the upper part 5, this member being disposed at the upper end and on the rear side of the faucet. At miollength on the inside the front wall of the cylinder is cut, as indicated at 34 in Figs. 2 and 3, to provide an operating space for the linger 35, which finger is mounted on a squared portion 36of a spindle 37 ,passed through the bore 38 of the cylinder, the inner end of the spindle being reduced to form a pintle 39 adapted to seat in a reduced bore 40 formed in the opposite inner end of the cylinder. Adjacent the squared portion 36 the spindle is provided with a collar 4l screw '46, as shown in Figs. 3

against which suitable packing 42 may be forced by means of a packing nut 43 screwed into the bore 38 which is interiorly threaded correspondingly to the nut. The spindle eX- tends through the nut and its outer end is squared, as at 44, so that the operating handle 45V may be mounted thereon, this handle being held in place by means of a small and 4. By this construction the handle and spindle can be removed without disassembling the faueet, which isnot possible with the `original construction, and further, a lever action is provided for operating the stem 30, thus enabling the spindle to be packed tighter than with the vertical depressiblc stem, which could not be packed tightly since the water pressure might not be suilicient to overcome the 4stem and packing friction if packed too tight. With the present arrangement, however, the packing may be compressed to any degree of tightness irrespective of any other considerations relating to the operation of the valve member and plunger.

The operation of the faucet will be readily apparent, on reference being` had to F ig. 2, in which the faucet is shown open, the valve member 22 and plunger 18 being depressed by means of the finger 35, which is in its lowest position, to which position it is carried by the swinging downwardly of the handle 45. During this downward movement of the plunger the upward' pressure of the water on its closed end is relieved by the provision. of the aperture 19, thus providing for free downward movement of the plunger. The downward travel of the plunger' is so arranged that, when at the end of its stroke, the aperture 21 registers with the aperture 17 of the liner 1,5, as shown in Fig. 2, which aperture 17 is in communication with the annular chamber 16, this chamber being normally supplied with water from the conduit through aperture 3. It will thus be apparent that, when the plunger is depressed to the end of its stroke, water will iiow through the aperture 3 of the nipple 10 into chamber 16 to pass through the liner aperture 17, the plunger aperture 21, the opening 29, the bore 28, and out through aperture 32 into chamber 8 to be discharged through the delivery spout 11.

Upon release of the pressure on the stem 30 the pressure of the water fiowing through aperture 17 into the space 24a acting on the closed end of the plunger 18 will raise the plunger, carrying the valve 25 upwardly to re-seat the same on valve seat 29, thus shut ting oif the flow of water through spout 11 and at the same time bringing the port 21 above the port 17, from which it will be seen that water cannot now flow from the faucet. What we claim as our invention is 1. In a faucet, the combination with a casing adapted for connection to a water supply and a depressible valve adapted for manual unseating to open the faucet and water-operated to reseat it and close the faucet, of a cylinder formed transversely on the upper end of the casing, the wall of said cylinder being cut at inidlength to provide an opening, said cylinder having a threaded bore on one side of said openingand a plain bore on its opposite side, a spindle rotatably mounted in said cylinder having its inner end fitting the plain bore thereof and an inner squared portion `in alinement with the wall opening, the outer end of said spindle being extended through and beyond the end of the threaded bore and provided adjacent the inner squared portion with alcollar and being squared at its extremity to receive an operatin handle, a nut mounted on the outer en of said spindle adapted to iit the threaded bore of the cylinder, and a linger mounted on the inner squared portion operable in the said wall opening the depression of which by the operation of the spindle de* presses the valve.

2. In a faucet, the combination with a casing having delivery and pressure chambers, a plunger vertically movable in said pressure chamber adapted to be raised by the water to close the water supply to said chamber and manually depressble to open it thereto, and a valve carried by said plunger, of a valve seat member removably mounted between said chambers consisting of a disk mounted in the upper end of the pressure chamber and provided with a central boss extending upwardly into the delivery chamber having a bore the lower end of which is formed as a valve seat with which said valve co-acts in its highest position to close communication between the chambers and an aperture extending from the bore through the side of the boss, a valve stem secured to said valve extending slidably through said bore and reduced in diameter opposite said aperture, and means for de pressing said stem.

3. In a faucet, the combination with a casing having delivery and pressure chambers, a plunger vertically movable in said pressure chamber adapted to be raised 'by the water to close the water supply to said chamber and manually depressible to open it thereto, and a valve carried by said plunger, of a disk removably mounted in the upper end of the pressure chamber and provided With a central boss extending upwardly into the delivery chamber having a bore the lower end of which is formed as a valve seat with which said valve co-acts in its highest position to close communication between the chambers and an aperture eX- tending trom the bore through the side of the boss, a valve stem secured to said valve extending slidably through said bore and reduced in diameter opposite said aperture, a rotatable spindle mounted transversely in the upper end of the delivery chamber, and a finger mounted on said spindle adapted to coact with the said `valve stem whereby the same is depressed by the depression of the linger through the operationof the spindle.
