Specification of Letters Patent.

Patented Oct. 17, 1911.

Application filed December 27, 1910. Serial No. 599,505.

'To all whom it may concern.'

Be it known that I, ANDREW SKJELSTAD, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented a new and useful Faucet, of which the following is a speciiication.

It is the object of the present invention to provide an improved faucet, and the invcntion relates more particularly to that class of faucets in which the valve is held normally closed by the pressure of the water back of it.

One of the disadvantages of the ordinary faucets of this class lies in the fact that the valve is liable to soon become cut and worn by sand and other sediment settling upon the valve seat. The present invention therefore aims to so construct the valve seat and arrange the valve thereon that the movement of the valve to open position will clear the seat of any sand or like sediment which may have settled thereon during a period of disuse.

Another disadvantage to be found in faucets of this class is that the operating stems soon become so loose that the pressure of the water against the valve will cause the valve to close with considerable force and noise. Also this quick closing of the valve is liable to result in its injury or in injury to the connections between it and the valve stem. The present invention therefore further aims to so mount the valve stem that it may be allowed to move freely or may be retarded in its movement depending upon the water pressure and other conditions.

In the accompanying drawings-Figure 1 is a vertical longitudinal sectional view, through a faucet constructed in accordance with the present invention, the valve stem and the connection between the stem and the valve proper being shown in elevation. Fig. 2 is a horizontal sectional view on the line 2*2 of Fig. 1, looking in a downward direction. Fig. 3 is a detailed perspective view of the valve stem, the valve, and the connecting elements between the stem and valve.

In the drawings, the faucet is illustrated as embodying a casing 5 having a discharge spout 6 of the usual form, and a valve chamber 7 which at one end is in communication with a casing 5 opposite the point of juncture of the spout 6 with the casing. The valve chamber 7 is tapered toward its end which communicates with casing 5, the inner surface of the wall of the chamber throughout the entire length of the chamber constituting a valve seat. Threaded onto the major end of the chamber is a nipple 8 designed to be connected to the pipe or other source of liquid supply to be drawn through the faucet. The casing 5 is open at its top and is exteriorly screw threaded as at 9. A cap 10 is fitted upon the said top of the casing and is formed axially with an opening 11 through which extends the stem 12 of the valve of the faucet. The stem 12 is arranged to turn in the cap l0 and near its lower end is formed with an eccentric or crank portion 13, and the lower extremity of the stem is fitted as at 14 in a bearing in the bottom of the casing. A collar 15 is formed or secured upon the stem 12 and by adjusting the cap 10, the said cap may be caused to bear with greater or less force upon the said collar and the stem so held as to be more or less readily turned. The reason for providing for this frictional binding of the stem will be presently made clear.

The valve proper is indicated by the numeral 1G and is preferably of frusto-conical form, there being disks 17 disposed against its major and minor ends and a pin 18 secured axially through it and holding the disks in place. At that end of the pin corresponding to the minor end of the valve, there are formed spaced ears 19 between which is pivoted one end of a link 2O the other end of which link has pivotal connection as at 21 with the outer end of a second link 22. This link 22 at its end opposite its end which is connected to the link 20, is pivoted to the crank portion of the stem 12. The pivotal connection between the two links is rather loose so that the valve 16, when not firmly seated in the minor end of its chamber, as for example when it is in open position or is being moved to this position, may rest upon the bottom of the chamber. The valve chamber is preferably of a length substantially equal to twice the length' of the valve itself so that as the valve is moved from closed to open position, it will ride along the bottom of its chamber from the minor toward the major end thereof and will push back any accumulations of sand or like sediment which may have formed upon the bottom of the chamber during a period of disuse. By thus arranging the valve within the chamber, it is practically impossible for particles of sand to become lodged between the surface of the valve and the surface f the valve seat at the minor end of the chamber and consequently the valve will act eiiiciently at all times to cut off the supply of liquid through the faucet. If the pressure of the water or other liquid behind the valve is not great, it is desirable that the valve stem 12 be freely movable so that the louT pressure will effectually close the valve and hold the same in closed position without leakage. However, where the pressure of the liquid is rather high, it is desirable that the cap be threaded down to bear frictionally upon the collar 15 and in this manner retard the turning movement of the valve stem 12. Vhen this is done, the pressure will not act to so quickly close the valve as to injure its connection with the valve stem.

What is claimed is:

1. A faucet, including a casing having a tubular connection intermediate the waterpipe nipple and the faucet discharge-spout, said tubular connection being tapered in the direction of said discharge spout, a tapered valve arranged to loosely move along the inclined surface of said tapered tubular connection, an actuating stem for said valve, and loosely-j ointed link connections -between said valve and said valve-actuating stem, whereby the valve is allowed to effectively close under low or high water pressure.

2. A faucet, including a casing having a tubular connection intermediate the faucetdischarge spout, said tubular connection being tapered in the direction of said discharge spout, a tapered valve arranged to move loosely along the inclined surface of said tapered tubular connection, an actuating cranked stem for said valve, and a plurality of links intermediate said valve and said valve-actuating stem and loosely connected together, one link being loosely connected to said valve and the other link being loosely connected to the crank-member of said valveactuating stem.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
