Claims.

The invention relates to a valved faucet, and more particularly to a mixing valve for liquid dispensing, such as hot and cold water.

The primary object of the invention is the provision of a valve of this character, wherein a single stream of liquid can be dispensed or shut off, and such stream will involve a single or several iiow volumes of liquid fed from independent sources, such for example as hot and cold water, the dispensed liquid stream being temperature controlled, without disturbing the volume thereof.

Another object of the invention is the provision of a valve of this character, wherein the control is effected from a single hand lever which is readily accessible above, sideways or forwardly of the dispensing faucet for the liquid.

A further object of the invention is the provision of a valve of this character, wherein the same is assured of a positive mechanical action and requires but one hand for its operation with immediate desired results in volume of liquid, as well as any temperature from hot to cold or vice-versa.

A still further object of the invention is the provision of a valve of this character, which is simple in construction, thoroughly reliable and enicient in operation, easily repaired, conveniently actuated, durable, neat in appearance, quick acting, readily operated, and inexpensive to manufacture and install.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, and illustrated in the accompanying drawing, which shows the preferred form of the invention, and pointed out in the claims hereunto appended.

In the accompanying drawing:

Figure 1 is a top plan view of a mixing valve constructed in accordance with the invention;

Figure 2 is a sectional view taken on the line 2-2 of Figure 1 looking in the direction of the arrows;

Figure 3 is a view similar to Figure 1, with the top cover plate removed;

Figure 4 is a sectional view taken on the line 4 4 of Figure 2 looking in the direction of the arrows with the operating lever in dual actuating position and Figure 5 is the same in a single actuating position.

Similar reference characters' indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, A designates generally a faucet comprising a hollow body Il) formed with a pouring spout I I which leads from the mixing cavity I2 created by the hollow in said body, so that liquid delivered into the said cavity will be discharged or dispensed therefrom through the spout.

Threadably received in the bottom I3 of the body Ill are externally threaded nipples I4 which are adapted to be connected to hot and cold water service lines, respectively. These nipples I4 are arranged at opposite-sides of the spout and have communication with the cavity I2 in the body IIJ through openings I5 formed in the bottom I3, while adapted to open and close these openings I5 are vertically movable valves I6, one for each opening.

The valves I6 have their stems I'I projected upwardly through bonnets I8 detachably threaded onto the body Iii at the upper neck portions I9 thereof, which are integral with the said body. The stems I1 of the valves I6 have the multiple

square threads

20 and 2| thereon screwed into the necks I9, the threads 20 being reversed to the threads 2 I, so that when the said stems I'l are reversely rotated the valves I6 will be seated or unseated simultaneously with respect to each other.

Fixed in the body Ill, centrally between the neck portions I9, is a verti-cal pivot post 22 on which is mounted a horizontally swingable inverted U-shaped bracket or movable turntable 23, which has formed onthe upper end thereof the framelike structure 24 carrying the cover plate 25 over the forward portion thereof, and provided with the cutout 26 in the rear thereof. Mounted in the framelike structure 24 transversely thereof, is the pivot pin 21 on which, centrally thereof, is iixed the eccentric roller 28 which has threadably secured therein the hand lever 29. The eccentric roller 23 has a movement equal to approximately one fifth of a rotation, and the handle 29 entering the cutout 25 permits such rotation as shown in Figure 4.

The eccentric is rotatably mounted in the parallel upstanding ears 3l! and 30 respectively formed on the gear 3|. The gear 3| is turnable and slidable within the bracket 23, and is loosely mounted to allow lateral or horizontal play as the eccentric is rotated by means of the handle 2S. Movement of the handle up and down causes backward and forward movement [of thegear 3|;

while sideward movement of the handle'Z causes rotation of the gear 3l.

When the handle 29 is in the cutout 26 in the frame 24, and the cutout 32 in the ear 3D' on the gear 3|, the temperature of the water from the faucet is controlled by the lateral movement of the handle 29 which causes the gear and bracket 23 to rotate simultaneously. The angle of the handle 29 is formed to properly operate the valves I6.

The eccentric which is located between the ears on the gear 3|, moves gear 3| to its various positions, through the movements or hand lever 2d.

The teeth of the gear 3| are adapted for meshing engagement with the sector-

shaped gears

32 and 33 iixed to the stems i1 respectively by screws 34. The hand lever 29 controls the shifting of the gear 3l, while the lateral turning of the bracket 23 controls the rotation of this said gear 3|.

When the gear 3| is shifted rearwardly by the forward and upward motion of the lever 23, so that the axis of rotation of the gear 3| will coincide with the axis of rotation of the bracket 23, both valves it open to an equal extent, then if the bracket 23 is rotated on the post 22, the proportions of the mixture and consequent temperature of the liquid may then be controlled, the hand lever by its connection to the eccentric 28 being a single medium for these controls.

The cover plate may have thereon appropriate markings or indicia for indicating the on and "oi now of liquid and the temperature control thereof.

The multiple threads 20 and 2l are arranged so that a partial turn of the stems il is suiiicient to open the valves i3.

When the valves are partially opened, the gears Sil, 3| and 33 respectively, are in the position shown in Figure 2 of the drawing, that is to say, they are in transverse alignment with each other crosswise of the body iii of the faucet, i, e., to open the said valves, further, th;J hand lever 22 is pushed upwardly as in Figure 5. Then when it is desired to close the valves I5, the hand lever is pushed downwardly as in Figure When valves |65 are closed,

gears

32 and 33 are slightly to the front of the alignment of all these gears, and this position of the gear 3l allows for changing the fulcrum of this gear when it moves forwardly. The eccentric 33 provides the movement for the gear 3| which movement compensates for lateral play or movement when in operation.

When the gear 3| is moved forwardly and rearwardly of the alignment of

gears

32 and 33, that is, when valves it are opened full, gear ti has moved in front of the alignment of

gears

32 and 33 about the same amount as when the valves i6 are closed and gear 3| is moved back of alignment of

gears

32 and 33.

This full movement forward oi gear 3| caused by pulling up on the lever 2S gives you the full volume and pressure of one valve, that is, iifty per cent for each, due to each valve opening half way. Now by lateral movement either way, one valve will tend to close as much as the other will open, until one is closed completely and the other is open completely.

Either valve may be opened full without opening the other one, by pulling up lever 29, and at the same time pushing it backward or pulling it forward.

When only one liquid is desired, such as all hot (or all cold) water, the hand lever 29 is pulled upward, and at the saine time pressed or pulled forward as much as gear will allow. By doing this, only one liquid ows, such as all hot water, in the desired amount. This movement of lever 29, that is, up and to you, will open only one valve, and up and away from you will open only one valve.

It is believed that from the foregoing description, the construction and operation of the device will be apparent to those skilled in the art, and it is to be understood. that changes in the minor details of construction, arrangement and combination of parts may be resorted to, provided they fall within the spirit of the invention and the scope of the appended claims.
