Specification of Letters Patent. Paitamtdl Apr'. 22, 1919.
Application filed .Tune 28, 1917. Serial No. 177,545.
To all whom z' may concern Bev it known that I, LLOYD LA VALLEY, a citizen of the United States, residing at Schofield Barracks, in the Territory of Hawaii, have invented certain useful lmprovements in Faucets, of which the following is a specification, reference being had therein to the accompanying drawing.
The present-invention relates to faucets, particularly of the quick compression type, and has for an object toprovide a. faucet, the handle of which is in the `form of a plunger adapted to be forced inwardly a slight distance to fully open the faucet for admitting the full flow of liquid therethrough.
Another object of the presentinvention is to provide an improved locking means for holding the plunger in its fully depressed position, sov that the faucet may be left open for any desired length of time, this object of the invention also contemplating the provision of improved mea-ns for quickly re-v leasing the plunger when it is desired to close the faucet.
Other objects and advantages of this invention will be brought out in the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawing, wherein- Figure 1 is a vertical sectional view taken centrally through the faucet.
Fig. 2 is a top plan view thereof.
Fig. 3 is a transverse section taken on the line 3- 3 of Fig. 1.
Referring to this drawing, there is provided the body or casing 10, which is cast in one piece, and which has an exteriorly threaded nipple 11, by means of which the body may be attached to a lavatory fitting or thelike, and t0 this nipple is adapted to be connected the supply pipe. At the inner end of the nipple there is formed an exteriorly extending escutcheon 12 while formed in the body and alining substantially with the escutcheon is a transverse wall 12. The bodyis also provided forwardly of the wall with'a transversely extending web 13, which is open at one side to establish communication with the mouth or outlet spout 14, the latter being curved laterally from the body at a point considerably beyond the web 13.
A valve seat 15 is formed centrally' in the wall 12 and establishes communication between the, nipple and the outlet spout. The body of the faucet is provided on its outcr surface and forwardly of the escutcheon 12 with an annular series of wrench receiving faces 16, by means of which the faucet may be screwed into place. '.lheyweb 13 is in longitudinal alinement with the valveseat 15, and is provided with a forwardly facing seat therein. Forwardly of the web 13, and in line therewith, the body is provided with a longitudinally extending cylinder 17, provided in one side with an apertured projection 18, which extends oppositely from the spout 14. y,
A. valve stem 19 is positioned in the body 10 and spaced from its wall, and is preferably inserted outwardly through the shank 11. The inner end of the stem 19 carries a valve 20, having a kerf 2l in the outer face thereof, to receive a screw driver or the like for turning the stem into and out of position. The stem 19 projects outwardly through the valve seat 15 and through the web 13 Iinto the cylinder 17. A packing washer 22 isl slipped over the outer end of the stem 19 and forced inwardly into engagement with the seat on the web 13. A metallic washer 23 is also slipped over the outer end of the stem 19 and bears against v the resilient washer 22. A spring 24, of the helical type, is fitted in the cylinder 17 about the stem 19 and bears at its inner end against the washer 23. A plunger 25 is slidably fitted in the outer end of the cylinder 17, and has in its inner end an internally threaded opening, into which the out'er end of the stem 19 is adapted to be screwed. The plunger 25 receives the outer end of the spring 24 thereagainst to compress the same and draw the stem 19 outwardly to seat the valve 20 against the valve seat 15, and hold the resilient washer 22 against the seat of the web 13. The plunger 25 is provided with a push button 26 on its outer end, adapted to be engaged by the hand to force the plunger and the stem 19 inwardly against the tension of the spring 24.
A longitudinally extending slot 27 is formed in one side of the plunger 25 to receive therein the inner end of a bolt 28, which is mounted in the projection 18 of the cylinder, and which is urged inwardly against the plunger 25 by a spring 29. The spring 29 is housed in the projection 1S. A head 30 is screwed upon the outer end of the bolt 28 and is adapted to be grasped for retracting the bolt from engagementwith the plunger 25. The plunger 25 is provided at the outer end of the slot 27 therein, with a notch 3l, forming a keeper adapted to re` 'stance as having external screw threads, by
means of which the pipe may be attached to the faucet.
It is of course understood that this nozzle may be of any desired construction other than here shown,with0ut departing from the spirit of the invention.
In operation, the spring 24 normally holds the valve 2O against the valve seat 15, and thus prevents the How of fluid outwardly through the nipple 11 and body of the valve. When it is desired to open the valve, it is only necessary to depress the plunger 25, and when the plunger is fully depressed, the bolt 28 springs into the notch 31. and holds the plunger in its inner position against the tension of the spring 24. To close the valve, it is only necessary to draw the head 30 outwardly and retract the bolt 28 from engagement with the plunger 25. As soon as the plunger is released, the spring 24 moves the plunger outwardly and moves the valve 20 into closed position.
The valve body, and its parts, may be made of any suitable material, and may be given any form Whichis found adaptable in its manufacture, and for various uses.
What is claimed is i A faucet comprising the body cast in a single piece and provided with a sinuous mouth, an exteriorly threaded nipple integral with and projecting from the inner end of the body, an annular and eXteriorly eX- tending escutcheon integral :with the body and positioned at theinner end of the nipple, a transverse wall formed in the body and positioned in alinement with the escutcheon and formed with an opening constituting a valve seat and also establishing communication between the nipple and the mouth, the body being formed in its forward end with a hollow cylinder whichl alines substantially with the nipple and has the inner end formed with an opening alining with the valve seat, a valve disposed in the nipple and designed for engagement with the seat, a stem projecting from' the valve and arranged through the seat and the opening in the cylinder, a plunger detachably connected to the opposite end of the stem and slidably arranged in the cylinder, a spring positioned in the cylinder and about the stem for yieldingly holding the plunger in a forward position and the valve against the seat and a yieldingly mounted locking bolt in the cylinder and engageable with the plunger for normally preventing rotation of the plunger and for locking the plunger, at times, in a depressed position soas to releasably hold the valve in an open position.
ln testimony whereof l afliX my signature.
