FAUCET.

SPECI'ICATION forming part of Letters Patent No. 430,? 12, dated June 24, 1890.

Application filed May 3, 1889. Serial No. 309,451. (No model.)

To all whom it may conccrn;

Be it known that I, WILLIAM VANDERMAN, of VVillimantic, in Windham county, Connecticut,have inventedcertain new and useful Improvements in Faucets which improvements are described in the following specification and are illustrated by the accompanying drawings.

My invention relates to that class of faucets in which a valve is operated by means of an eccentric-spindle engaging the valve-sten. Faucets of this class as heretofore constructed present several disadvantages. After becoming somewhat worn by use, such a faucet cannot be fully and positively closed by turning the spindle, and when set open will frequently close itself automatically underthe influence of the supplied current. This automatic closing of the valve results from the circumstance that the direction of motion of the supplied current and the direction of motion of the Valve in closing are largely coincident. Again, such a faucet, in order that the valve may be accessible for renewal. and repair, is necessarily made in separable pieces, including the body of the faucet and a tail-piece or thimble, which is screwed thereon. The screwing and unscrewing of these parts is frequently inconvenient, and in some situations is destructive to pipes, fixtures, and Wood-work. Moreover, the wear between the same parts often causes the joint to leak or the perpenlicular portion of the faucet to w'ork out of To obviate these and other disadvantages is the object of the present invention. To accomplish this object, I locate the snpplyinlet at one side of the valve, place a removable cap at the top of the supply-chamber, and make a screw-connection between the Valve and the valve-stem.

In said drawings, Figure 1 is a side view of Fig. 2 is a central vertical section of the same faucet. Fig. 3 is a face View of a stop-cock which is constructed in aecordance with my invention in a modified form. Fig. 4 is a central vertical section of said stop-cock. Figs. 5 and 6 are cross-sections on x a: and y y, respectively, of Fig. l.

lVith primary reference to Figs, 1 and 2, the nuneral 1 denotes the case or body of the faucet, which is a shell of irregular cylindrical form. In the middle part of the body 1 is located the valve-seat 2,which is circular in cross-section and diminishes in size from top to bottom gradually. Above valve-seat 2 is the supply-chamber 3, and below said valve-seat is the outlet chamber or nozzle 4. Chamber 3 is closed at the top by cap 5, screwed upon the end of body 1 and having an upwardly-extcnding recess or concavity 6.

At one side of body 1, integral therewith, and opening into chamber 3 at one side, as distinguished from an end of said chamber, is located the inlet-tube 7. Upon the opposite side of body 1 is the 'hub 8, which contains the concentric body of the rotatable eccentric-spindle 9, together with suitable packing 19, which is held in place by cap 20. The outer end of this spindle is provided with a handle 10 in the usual manner, while the inner end of the same terminates in an eccentrio-pin 11 within chamber 4. Pin 11 engages a Valve-stem 12 in the usual manner. The Valve or plug 13 is preferably of india-rubber or caoutchouc and has the form of a frustum of a cone inverted. Through the middle of Valve 13 is a hole for the accomnodation of screw 1 1. Above Valve 13 on screw 14 is a washer 15, and above the latter is an adjustable nut 16. Below valve 13 011 screw 14: isnut 17, which is also adjustable thereon. Screw 14: is turned a variable distance adjustably into a screw-threaded hole 18 in 4 the free end of stem 12.

Such being the Construction of my invention in the form which is illustrated in Figs. l and 2, the mode of its operation .is now to be explained. The turning of spindle 9 by handle 10 opens and closes the faucet in the usual manner. If the faucet be set open, the supplied current, noving in a general direction at right angles With the longitudinal axis of body 1, inpinges chiefly upon that side or portion of valve 13 which is nearest to tube 7 and tends to move the valve horizontally in the direction which is indicated by the arrow. This tendency being transmitted through sten 12, acting as a lever, and also through spindle 9, causes said stern to bind upon pin 11, and also said spindle to bind in hub8, so that said spindle is held in a fixed IOO position relatively both to hub 8 and stem 12. consequently the faucet cannot close itself automatically when left open. After stem 12 and pin ll become worn, valve 13, tending to move in the described direction, may be forced, when open, into contact with that portion of Valve-'seat 2 which is farthest from inlet 7, and such contact, when it occurs,will also prevent the automatic closing of the faucet. Again, the concavity 6 of cap and the upward extension of chamber 3 above the level of tube 7 conspire to produce an aircushion, which prevents the occurrence of water-hammer when the faucet is suddenly become worn, the latter must be brought nearer to pin 11.

It is one of the merits of this invention that the same can be advantageously applied i in a modified form to the Construction of a stop-cock, as illustrated in Figs. 3, 4, 5, and 6. Certain parts of the stop-cock which is shown in the last-mentioned figures are indicated by the same numerals which have been ap- 'plied to corresponding parts in Figs. 1 and 2. The stop-cock, however, requires additional description. In this modification of my invention the inlet-passage 7 and the outletpassage 4 are arranged in line, and the body 1 of the cock branches therefrom at right angles. The interior of body 1 is divided throughout a portion of its length into two chambers by means of adiaphragm 21, which is formed integrally with said body. These chambers or compartments are a supplychamber 22, which intercommunicates with supply-passage 7, and an 'outlet-chamber 23, which opens into the outlet passage 4. The valve is seated at the entrance to chamber 23 in the samc manner in which the valve :in Fig. 4 is seated at the entrance to outletchamber 4, as above described. Spindle 9 is 'journaled in a tapering plug 24, which serves as packing therefor and is rotatable therewith. This plug is perforated by an interior waste-channel 25, which commences at the inner end of said plug and extends to said line of section y y, 'there turns, and thence proceeds to the side of said plug, as seen in Figs., 4 and 6. When the cock is closed, hole 25 is continuous with a hole 26 through the side wall of hub 8. The mode of operation of this stop-cock as distinguished from the faucet which is above described is in other respects similar to the described mode of operation of said faucet and to the well-known mode of operation of stop-cocks of the same generic type.

It is to be observed that a faucet constructed as described and having its handle parallel to the outlet can be inserted in some situations in which a faucet of the kinds heretofore constructed would be inadmissible for lack of space; also, that when the described stop-cock is joined to the pipe in which it is inserted the cock may be opened for repairs, &0, by simply unscrewing cap 5 and without disturbing said connections.

Such being the Construction and operation of my invention, I claim- 1. In a cock or faucet having its supplyinlet at substantially a right angle to its body portion, the combination of a valve-seat in said body portion, a lifting-valve playing up and down therein at substantially a right angle to the supply-inlet, and an Operatingspindle carrying a crank or eccentric pin fitting closely an eye in the' valve-stem, the spindle having an aXis parallel with the sup ply-inlet, and the valve being supported and guided wholly by the pin, as and for the purpose set forth.'

2. In a cock or faucet having its supplyinlet at substantially a right angle to its body portion, the combination of a valve-seat in said body portion, a lifting-valve playing up and down therein at substantially a right angle to the supply-inlet,.a screw-capped socket proj ecting from said body portion parallel with the supply-inlet, a spindle journaled within said socket, a crank or eccentric pin carried by the spindle, and a valvestem havinga transverse eye at its lower end closely fitting said pin and a longitudinal screw-threaded opening in its upper end, into which passes a screw-threaded pin passing' centrally through the Valve-plug, as and for the purposes set forth.

3. In a faucet having its supply-inlet at substantially a right angle to its dischargeoutlet, the combination of a valve-seat in the body of the faucet below the inlet, a screwcap extension of said body portion above the inlet, forning an air-eXpansion chamber beyond the reach of the Valve, a screw-cap socket projecting from the body below the inlet and parallel therewith, a'valve adapted to fit the seat and to play up and down at a right'angle to and across the inlet, a bushed spindle turning in said socket and projecting into the body portion and carrying an eccentric-pin, a valve-stem having an eye at its lower end closely fitting the pin, a longitudinally-threaded opening in its upper end, a valve-plug, and a threaded screw or pin pass ing icentrally through the plug and into the opening in the stem, whereby the plug may be accurately adjusted to fit the seat by turning the threaded pin, substantially as described.

In testimony whereof I have hereunto set my name in the presence of two witnesses.

WILLIAM VANDERMAN.
