WATER-FAUCET.

SPECIFICATION formingpart of Letters Patent No. 662,508, dated November 27, 1900'. Application filed February 19, 1960.. stun No. 5.807. (No model.)

To all whom it may concern:

Be it known that LRICHARD H. W. SCHMIDT, a citizen of the United States, residing at Kansas City, Jackson county, Missouri, have in-,

from water freezing in the pipe.

sure of the water.

A further object is the provision of a fancet wherein the valve may be unseated quickly and easily against the resistance of Waterpressure.

To these ends the invention consists in certain novel and peculiar features of construction and combinations of parts, as will be hereinafter described, and pointed out in the appended claims, and in order that the invention may be fully understood reference is to be had to the accompanying drawings, in which Figure 1 is a vertical central section of a water-faucet embodying my invention, the valve being shown as seated under the pres- Fig. 2 is a detail View illustrating the valve as partly unseated.

Referring now to the drawings in detail, 1 designates the easement of the valve, provided with the internal perforated partition 2, dividing the interior of the easement into chambers 3 and at, the latter having an outlet nozzle or spout 5. The receiving end of the easement is externally threaded, as at 6, to screw into the stand or supplypipe. (Not shown.) At the opposite end of the casement the externally-threaded neck 7 is provided, the passage of the same being in iongitudinal alinement with the perforation of partition 2, and mounted upon said threaded neck is a packing-nut 8.

9 designates the valve-stem of cylindrical form and extending reciprocally through neck 7 and packing-nut S and having a wator-tight connection with the latter,which can be maintained by screwing the nut downward as the packing wears under the frictional action thereon of the stem. At the outer end of the stem is formed a cap or handle 10 to receive the pressure of the operators hand, though it is to be understood that any desired type of handle for forcing the stem inattaining a position nearer the most advanced point of the end of the stem than the other for a purpose which will hereinafter appear.

13 designates a screw-bolt depending axially from the valvestem through the partition-perforation and provided at its lower end with an angular head 1 1 by preference.

The valve proper is constructed as follows:

15 designates a washer mounted loosely upon the bolt and adapted to seat squarely up against the partition 2 and prevent water from passing between it and the partition and up through the perforation of the latter, and in order that this washer may be as strong and durable as possible I prefer to make it of fiberinstead of rubber, though the latter of course may be employed.

16 designates a metallic washer also flitting loosely on the bolt and interposed between the head of the latter and the fiber washer and provided with a depending annular externally-threaded flange 17, loosely enveloping the head of the bolt.

18 designates an inverted metallic cap screwed upon the depending flange 17 of the metallic washer, and in order that the joint between said metallic washer and cap may be absolutely water-tight and grow more perfect with service said parts are preferably made of brass, it being well known that the frictional action of brass against brass will effect a perfect joint by reason of one part adapting itself to the other.

From the foregoing it will be seen that the valve fitting loosely upon the bolt is permitted direct reciprocal movement thereon, but may tilt and accommodate itself to the oblique inner end of the valve-stem. When the pressure is off, the valve is automatically and immediately unseated under the pressure of air entering chamber 3, assisted by the gravitative tendency of the valve, thereby admitting air to the stand or supply pipe and by effecting a thorough drainage of the latter eliminating all chance of the water freezing in the pipe. When the water is turned on again,

it instantly forces the valve against the seat and prevents the escape of water through the in contact with the fibrous washer. The continued pressure then causes the washer to fulcrum against the partition 2 at a point diametrically opposite the point of engagement with said stem, which results in a very gradual exposure of the partition-perforation and the lower end of the most advanced passage 12 in the stem to the water in chamber 3,

which of course relieves the pressure in the pipe materially and permits the continued operation of the valve-stem to take place without-difficulty, said operation being continued by preference until the oblique end of the stem protrudes entirely into chamber 3, and

the valve is can ted upon the bolt 13,the washer 15 hearing squarely against the oblique end, and consequently occupying a position at an angle to the stem. When the pressure is removed from handle 10, the water will reseat the valve and force the valve-stem back to the position shown in Fig. 1.

It will thus be seen that by providing the stem with'an oblique inner end the operator is given a leverage on the'water under pressure equal to the distance between the point of contact on the stem with Washer 15 and the periphery of the latter at a point diametrically opposite its point of contact with the stem, which leverage enables the operator to unseat the valve with much greater ease and despatch than if the whole power of the water-pressure had to be overcome by forcing the valve bodily away from its seat. In the former case the operator not only has the leverage to displace the water, but need displace it only very slightly, while in the latter case a considerable volume of water, comparatively viewed, must be displaced in the movement of the valve bodily from its seat to admit the water simultaneously to the perforation of the partition from all sides of the washer 15.

A defect common to all faucets with which I am familiar and remedied in this one is the failure to admit air to the pipe after the pressure is cut off, the admission of'air being desirable to effect the thorough drainage of the pipe and eliminate all chance of water freezing therein.

It is to be understood, of course, that. while I have illustrated and described the preferred embodiment of the invention I reserve the right to make such changes in the form, proportion, detail construction, or arrangement of the parts as shall not involve a departure from the spirit and scope or sacrifice any of the advantages embraced in the construction recited by the appended claims.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A water-faucet, comprising, acasement having aperforated partition, a rigid valvestem projectinginto the easement and through the partition-perforation, and a valve carried loosely by said stem so as. to reciprocate and tilt thereon and adapted to be seated and close the perforation of the partition by the pressure of the water and unseated when the pres- .on the end of the stem and through the partition-opening, and a valve carried loosely by said extension and adapted to reciprocate and tilt thereon and be forced against the perforation of the partition by the pressure of the water and to be unseated gradually by the Valve-stem or by gravity or atmospheric pressure when the water is shut off, substantially as described.

3. A water-faucet, comprising a casement, having a perforated partition, a valve-stem projecting movably therein and provided with an extension of smaller diameter having a head or enlargement at its inner end, and a valve mounted upon said extension so as to reciprocate thereon or tilt at an angle thereto, and adapted to be unseated when the pressure is shut off, and rest upon the enlargement of said extension, substantially as described.

4. A water-faucet, comprising a casement having a perforated partition, a valve-stem projecting movably therein, a bolt projecting from the stem to the opposite side of the partition, and a valve mounted upon said bolt and consisting of a compressible washer, a metallic washer inward of the same, and a metallic cap screwed to the metallic washer and completely enveloping the inner end of the bolt, substantially as described.

5. A water-faucet, comprising a casement having a perforated partition, a valve-stem projecting movably therein, a bolt projecting from the stem to the opposite side of the partition and provided with a head, and a valve mounted upon said bolt, and consisting of a compressible washer, a metallic washer between the partition and the head of the bolt, the bolt-passage of the latter being of smaller diameter than the head of the bolt to prevent the dislocation of the washer, and a metallic cap loosely enveloping the head of the bolt and screwed to said metallic washer, substantially as described.

In testimony whereof I affiX my signature in the presence of two witnesses.
