WILLIAM GEURINK, OF CLEVELAND, OHIO;

FAUCET.

SPECIFICATION forming part of Letters Patent No. 646,979, dated .April 1o, 196e. Application filed February 8, 1900. Serial No. 4,539. (No modell) T ctZZ when?, t may concern.'

Be it known that I, WILLIAM GEURINK, a resident of Cleveland, in the county of Cuyahoga and State of` Ohio, have invented certain new and useful Improvements in Faucets; and I do hereby declare the following to be a full, clear, and exact description of the invenoperating mechanism is such as to insure the upper portion of the faucet.

automatic closing of the valve and prevent the same from being tied or plugged, so as to remain open.

This invention consists of certain details of construction and arrangements of parts, which will be fully set forth hereinafter in the specification, illustrated in the drawings, and pointed out in the claims.

Referring to the drawings, Figure 1 represents a central vertical section of my faucet. Fig. 2 is a view in elevation, showing the Fig. 3 is a vertical section on line 3 3, Fig. l. Fig. I is a vertical section on line e 4, Fig. 3.

Referring to the drawings, ct indicates the body of my faucet. This body is provided with a valve-seat ct' and a nozzle a2. The upper portion of the body is reduced to form a neck portion a3. This neck portion is screwthreaded interiorly. Adapted to partially screw into this neck portion is a nut b. This nut is provided with exterior shoulders b', which abut against the rim of the neck a3. The nut Z2 is bored centrally to permit the passage of ,the upper portionof the valvestem c. The bore of this nut b is regularly reduced in diameter, so as to form shoulders b2, b3, and b4 on the interior of the bore. The top surface of the nut b is provided with a circular track b5, consisting of three concave grooves or double inclines arranged around the bore of the nut.

The valve-stema is provided with a valve c. N ear its upper end the valve-stem cis reduced in diameter to form a neck portion c2,

the bore of the nut b, and form a stop which prevents the further upward movement of `the valve-stem.

Closely fitting the valve-stem c is a sleeved washer f. This washer is adapted to lit into the bore ofthe nut b and abut against the shoulders b3, formed therein.

I'Ieretofore in faucets of this character the packing for the valve-stein has been placed between the under side of the retaining-nut and shoulders formed on the valve-stem. In this position the packing was rapidly disin tegrated by the impact of the shoulders of the valve-,stem when the faucet was operated. Moreover, when placed in this position the wearing away of the washer is especially detrimental to the operation of a faucet of this character, as the worn washer permits too much of the valve-stem to passV through the bore of the retaining-nut,,widening the space between the surface of the nut and the bottom of the handle. The friction-balls are then no Vlonger retained in their respective grooves, and the operation of the faucet is greatly impeded.

In mypconstruction the valve packing is sleeved on the valvestem and adapted to fit into the bore of the retaining-nut, where it abuts against a stop formed therein. The valve-stem slides up and down through this packing, and the shoulders thereon abut against the retaining-shoulders formed in the bore of the nut.

inappreciable, and the handle will therefore 4 As the respective shoulders y `are formed of metal, the wear thereof will be be constantly held in its relative position to v the upper surface of the nut. v

Encircling the valve-stem and resting on the valve c' is a coiled spring d. Between the top coils of this spring and the valve-stem is a collar c. This collar is provided with aprojecting annular flange e. The bottom surface of` this flange is inclined in the form of a spiral, so as to conform to and rest evenly upon the top coil of the spring. This flange 'c' prevents the collar from slipping down between the valve-stem b and the spring d, and

as its under surface conforms to the curvab to enter therein.

ture of the top coil of the spiral spring t-he collar will be evenly supported thereby and will not tip to one side, as is the case when the under surface of the fia-nge is flat and touches the top coil of the spring only at one point. The top of the collar presses against lthe packingf, securely holding it in place. The top surface of the flange e abuts against the shoulders b4, formed in the bore of the nut b, thus keeping the spring Z under a constant pressure.

The valve mechanism is operated by means of a hollow bulb-shaped handle formed in two parts h and h', adapted to screw into each other. The surface of the top portion is made very smooth, so that dust or dirt will not settle or collect thereon. In order that the handle may be securely grasped, the surface of the lower portion is roughened, preferably by forming a series of concave indentations h2, and as these indentations are on the under side of the handle dust or dirt will not collect in them. The lowerportion is also provided at its greatest circumference with a raised band h3, having a milled surface. A 4diaphragm Z, formed integral with the lower por tion h', divides the interior into two circular cavities n and n. This diaphragm is bored centrally, so as to allow the passage of the valve-stem. The diameter of the lower cavity is sufficient to permit the head of the nut The sides of this cavity inclose the top of the nut and prevent dust or other foreign substances from working in between the handle and the surface of the nut. The under surface of the diaphragm is provided with a circular track composed of three concave grooves or double inclines corresponding to the grooves or inclines on the head of the nut.

When the lower portion of the handle is l placed on the nut b, the end of the valve-stem projects upwardly through the bore in the diaphragm Z. This end is screW-th-readed to receive lock-'nuts 0 and o', which secure the valve-stem in the handle.

A metallic Washer o3 is placed around the valve-stem between the diaphragm Z and the nut o. As the greatest amount of friction will be between this nut and the diaphragm,

it is necessary that these parts be well lubricated. I therefore form on the upper surface of the diaphragm Z an annular' flange m inte gral with the said diaphragm. This flange forms a cup for retaining grease or other suitable lubricant where it will feed to the parts as required.

Before securing the valve-stem to the hand-le friction-balls p are inserted between the bottom of the diaphragm and the nut l). When the faucet is closed, each ball occupies a central position in each of the respective grooves or inclines, which allows the handle to be turned to the right or to the left when it is desired to open the faucet.

When the `faucet has been assembled, the top portion 7L of the handle is screwed into the bottom portion 71,', protecting the work` ing part from dust and preventing tampering with or accidental displacement of the nuts securing the valve-stem in the handle.
