Hyde, Crystal River, Fla., assignor to Pryde, Inc., Cincinnati, Ohio, a corporation of Ohio Filed Aug. 29, 1966, Ser. No. 575,865 Claims. (Cl. 239-26) ABSTRACT OF THE DISCLOSURE A hot-cold water faucet in which the temperature of the water, the volume of the water, and the direction of the fiow of water issuing from the spout may be controlled by grasping and manipulating a single knob that is on the spout. The faucet includes a base that is adapted to be mounted on the rear deck of a sink. Two lines, which may be made in one integral piece, one for hot water and one for cold water, extend from the base to the spout. Provision is made for raising and lowering the spout relative to the base which controls the volume of water issuing from the spout. Turning the knob on the spout controls the temperature of the water issuing from the spout. Provision is also made for swinging the spout from side to side about a vertical axis through the base. Additionally, provision is made for rotating the spout about a horizontal axis extending through it. Thus, by rotating the spout around its horizontal axis, by raising and lowering the spout, and by swinging the spout from side to side the stream of water issuing from the spout may be directed into any part of the sink. Additionally, the spout is arranged such that as it is rotated about its own horizontal axis to direct a stream of water such that it might otherwise escape the bowl, the stream is shut off so that no water can escape the bowl.

This invention relates to faucets and it is directed in particular to a faucet in which the temperature of the water, the volume of the water, and the direction of the fiow of the water issuing from the spout are controlled by grasping and manipulating a single knob or handle.

For the purposes of this disclosure, reference is made to a faucet designed primarily for use at a kitchen sink. It will be obvious, however, that the faucet is not limited to use in this environment and that it is equally well-suited for use in other types of installations; for example, at a bathroom lavatory bowl.

The broad concept of having a single handle adapted to control more than one function of a faucet is not new, and there are a number of so-called single lever faucets on the market and there are a number of patents disclosing such faucets. However, in these single lever faucets the control has been limited to the varying of temperature and volume. Swing spouts have'been employed for single lever faucets such that the direction of the flow of water issuing from a faucet could be changed by moving the spout from side to side in a fixed arc, but this movement was not under the control of the lever and it was limited to the fixed arc. That is, the flow of water issuing from a swing spout could not be directed into all areas of the sink bowl. Thus, in the faucet of this invention a third control is provided such that the manipulation of a single knob or handle does three things. It varies the temperature of water issuing from the faucet in a range covering the limits of the temperature of the water in the hot and cold water supply lines. It varies the volume of the water issuing from the faucet from off to full on. In addition, it makes it possible to direct a stream of water into any area of the sink bowl, whether the bowl be a single one or a double one.

The faucet of this invention is adapted to be mounted upon the deck at the rear of a sink bowl, as is the common practice. The base of the faucet is adapted to be rotated about a vertical axis. In the preferred embodiment of the invention, two individual tubes, one carrying cold water, the other carrying hot, connect the base to a head. The head may be raised and lowered in an arc, the center of which is on an axis extending horizontally through the base and intersecting the vertical axis about which the base is adapted to turn. Further, in the preferred embodiment of the invention, the head carries a control knob that is adapted to be grasped and rotated about an axis that is in a plane common to the vertical axis about which the base rotates. In addition to this, the control knob is adapted to be swiveled about a horizontal axis that parallels the horizontal axis that is in the base and that is at the center of the are through which the head is adapted to swing. Thus, there are four axes about which the parts of the faucet are adapted to rotate or swivel.

Turning the head about its own horizontal axis causes the spout part, from which water issues, to turn and, for reasons to be explained, this turning movement preferably is through more than so that it is possible to turn the spout into a position in which it directs water upwardly. In this position, the faucet serves as a drinking fountain.

It will be seen, also, that the head of the faucet can be swung up and down, sideways, and that the spout can be pointed such that water issuing therefrom may be directed into any area of the sink bowl, and that the spout could be aimed in a direction which, but for an expediency to be explained, might otherwise direct the stream of water into areas outside of the sink bowl. Provision is made, however, to diminish the flow of water from the spout as the spout is directed toward the rim of the sink bowl and to completely shut it off as the stream approaches the rim of the bowl, such that no flow of water can be directed to areas outside of the sink bowl. Thus, it is possible to wash down all areas of the bowl without water escaping the bowl.

The volume of water issuing from the spout is controlled by raising and lowering the head with off being at the uppermost position of the head wherein the faucet is in a near-vertical position. The water is turned on increasingly as the head is swung down toward the sink bowl. The temperature of the water is controlled by rotating the knob on the head of the faucet. The direction that the flow of water takes is dependent upon the position of the head. All three controls can be accomplished with one hand, simply by manipulating the knob to either move the head or to rotate the knob on the head as desired.

Other features and advantages of the invention will be readily apparent to those skilled in the art from the following detailed description of the drawings in which:

FIGURE 13 is a view similar to FIGURE 12 in which the head of the faucet is directed outwardly toward the rim of the sink illustrating the manner in which the water is shut off as the spout direction approaches the rim of a sink bowl.

FIGURE 14 is a view similar to FIGURE 13 in which the head of the faucet is in a vertical position for use as a drinking fountain.

FIGURE 15 is a diagrammatic view illustrating the head of the faucet arranged such that equal amounts of hot and cold water issue from the spout.

FIGURE 16 is a view similar to FIGURE 15 in which approximately one part of hot water, for example, issues from the spout for approximately two parts of cold water.

FIGURE 17 is a view similar to FIGURE 15 in which the faucet parts are arranged such that all cold water flows from the spout.

The faucet of this in 'ention comprises three major components, a base 10, a head 11 and two water supply tubes, numeral 12 for the cold Water and numeral 13 for the hot water, that connect base 10 to head 11. The head 11 includes a control knob portion 14 and a spout portion 15.

Now going to the base portion of the faucet, the major part of the base is a core piece that is generally designated 16 in the drawings. As is best shown in FIGURES 5 and 8, the core portion of the base comprises a vertically disposed, generally cylindrical portion 17 and a horizontally disposed, generally cylindrical portion 18 that is atop of and an integral part of the vertical cylindrical portion 17. Core piece 16 may be cast as an integral part from a material such as brass or molded from one of the plastics that are compatible with water. The vertical cylindrical portion 17 of core 16 has two bores 19 .and 20 extending vertically therethrough with their axes diametrically opposed with respect to the vertical central axis of the vertical cylindrical portion 17 to provide two passageways, one for cold water and the other for hot water, the hot water passageway being designated 21 and the cold water passageway being designated 22. Since this view is from the rear of the faucet, the usual left-right, hot-cold relationship is reversed. The vertical cylindrical portion 17 of core 16 is surrounded by a base sleeve 23. These two parts are dimensioned such that there is a slip fit between them. Adjacent the bottom of core piece 16 there are three annular grooves 24, 25 and 26 that receive O-rings 27, 28 and 29. These rings seal off two annular chambers, one above the other. The first, designated by the numeral 30, is a hot water chamber and it is connected through a port 31 to a connector piece 32 that has the conventional water pipe coupling 33 attached to it. Coupling 33 is connected to a conventional hot water line 34. Below the annular hot water chamber there is provided a cold water annular chamber 35. This annular chamber 35 is connected to a cold water supply line 36 by means of a conventional coupling shown at 38. The water passes from the cold water supply line 36 into the cold water annular chamber 35 through a port 39.

Thus, the cold water supply is sealed by O-rings 28 and 29 and the hot water supply is sealed by O-rings 27 and 28, such that there can be no mixture of the two, hot and cold waters, flowing into the core piece 16.

The base 10 is adapted to be locked to the rear deck 40 of a sink bowl that is supported by means such as a panel of plywood 41 by means of the following parts. The base sleeve 23 has a groove 42 therein that is above the rear deck 40 of the sink. This groove 42 receives a snap ring 43. The snap ring also seats within an annular groove 44 of an escutcheon ring 45. The core piece 16 is locked into position by a circular base plate 46. Base plate 46 is held against the bottom rim of base sleeve 23 by means of a metal screw 47 that passes through an appropriately tapered bore in the base plate 46 and threads into the bottom of the core piece 16. For convenience, a locater pin 48 is provided extending from the lower end of the core piece 16 through an appropriate bore in base plate 46. The force of tightening screw 47 is transmitted to the upper end of the base sleeve 23 by means of a lip 49. Thus, the core piece 16 is locked in place relative to the sleeve, except that the core piece is free to rotate about its own vertical axis. The sleeve itself is secured to the deck of the sink by means of two elongated bolts 50-50 that pass through threaded bores in a ring 51 that is anintegral part of the base sleeve 23 and press against a bearing ring 52 that is underneath the plywood 41.

It should be noted at this point that the core piece and those parts that are attached to it can be removed from a sink installation simply by removing screw 47 and the plate 46. When this is done, the entire core piece can be withdrawn upwardly and it is not necessary to remove the hot and cold water supply lines from the faucet, as is required for conventional faucets.

Referring now to FIGURE 8, the two hot and cold water passageways 21-22 that extend up through core piece 16 are sealed at the lower ends by means of plugs 53-53. The upper ends of these two water passageways terminate short of the horizontal central axis of the horizontal cylindrical portion 18 of the core piece and adjacent their upper ends the passageways have ports 54-55 opening in diametrically opposed directions therefrom. 54 indicates the hot water port opening from vertical bore 20, whereas port 55 opens from the vertical bore designated 19, and is for cold water. The two

ports

54 and 55 are formed by drilling in from opposite sides of the ends of the horizontal cylindrical portion 18 of core piece 16. In each instance, the inner end of the port, either 54 or 55, is smaller than the outer portion thereof. In each case, the inner portion seats a sprin 56, whereas the outer portion seats a cylindrical valve member 57. The part of each valve member 57 that effects a seal is the outer rim 58 thereof.

Two end caps are afiixed to base 10. The one that is shown at the left in FIGURE 8 is designated 60 and it is for the cold water side, whereas the one designated 61in this figure is at the hot water side. These end caps are substantially identical with the exception that the end cap 61 at the cold water side carries a limit pin 62. As will be explained, this limit pin cooperates with a short arcuate groove 63 to limit the swinging movement of the faucet about the central horizontal axis B of the base 10. Both end faces of the horizontal cylindrical portion of the base are planar, and in each instance, there is provided an annular groove 64 at the periphery of end face. This annular groove '64 receives an annular rim 65 that is formed on an end cap and in between the rim and the inside of the annular groove 64 an O-ring 66 is seated.

The two end caps 6061 are held in place on the horizontal cylindrical portion 18 of base 10 by means of bolts '6767. In each instance, a bolt 67 has an enlarged, flat head 68 that is preferably recessed in the outer end of the end cap, a smooth cylindrical shank portion 69 that forms a pivot for the end cap, and a threaded portion 70 by which the bolt is fastened to the horizontal cylindrical portion of base 10. It is preferred that an O-ring such as the one shown at 71 be seated within an appropriate groove in the cylindrical shank portion 69 of each bolt to provide a seal. As shown in FIGURE 8, the two bolts are on the same, horizontal axis in alignment with one another. The inner face 72 of each of the two end caps is planar and as best may be seen in FIGURE 7, there is a port 73 in each end cap that cooperates with the two

ports

54 and 55 to permit water to pass through the end cap from port 73 into a straight passageway 74 that intercepts the port as shown in FIGURE 8.

Referring now to FIGURE 6, the outer rim 58 of each of the valve members 57-57 is held against the planar face 72 of each end cap by means of the springs 56-56 and as the end caps are rotated with respect to the ports 54-55 shift relative to the two ports 7373 in the two end turned full On or completely Off or caused to issue from the ports in any volume from 'full On and full Off. The manner in which this relative rotation takes place and the reasons therefor will be explained later. In any event, the amount of such relative rotation is limited by means of pin 62 and the groove '63 that is in the end of the horizontal cylindrical portion of the base at the cold water side thereof. The limits are illustrated in FIGURE 6.

The lower ends of the two hot and

cold water tubes

12 and 13 are affixed in appropriate seats within the two end caps such that they open into the two passageways 74-74, see FGURE 7. At this time, it can be seen that as the head 11 is raised and lowered, the two ports 54-55 shift relative to the two ports 7373 in the two end caps, 60 for the cold water and 61 for the hot water, so that a control for the volume of water supplied to the head is provided. In the preferred embodiment of the invention, the ports 54-55 are disposed relative to the two ports 73-73 in the respective end caps, such that there is complete alignment with the respective ports when the two hot and cold water tubes approach a nearhorizontal position and that there is complete misalignment when the tubes approach a vertical position. One of the great advantages to this arrangement is that the whole faucet is up and out of the way-when the water is Off and when the water is full On, the head from which the water issues is down close to the sink bowl. In intermediate positions, there can be a flow of water obtained from the head, and thus, it is possible to obtain water frornthe faucet even though the sink is full of dishes. For example, a coffee pot can be filled from the faucet even though the sink bowl is full of water. Further, the elevated position of the spout, with water running from it, makes the washing and peeling of vegetables much easier than at a conventional faucet.

Both tubes, 12 for the hot and 13 for the cold water, have sleeves aflixed to their upper ends. The one at the upper end of the hot water tube 12 is designated 75 and the sleeve at the upper end of the cold water supply tube is designated 76. In assembly, these two sleeves are on the same horizontal axis C, and they seat on two cylindrical projections that extend from diametrically opposite sides of the spout portion of the head, the projection at the left, as viewed in FIGURE 10, being designated 77 and the cylindrical projection at the right being designated 78. In each instance, there is a deep groove 37 surrounding the cylindrical projection in which the inner end of the sleeve seats.

There is a port 79 in each sleeve that opens to the inside of each of the

tubes

12 and 13. With the head of the faucet in a relatively vertical position, the ports 7979 are in alignment with flared ports 8080 that are cut through the sidewalls of the two cylindrical projections 77-78. These flared ports are toward the rear of the head of the faucet when it is in a relatively vertical position. The reason for this Will be explained. The joint between a sleeve and a cylindrical projection, at each side of the head of the faucet, is sealed by two O-

rings

81 and 82 that are in appropriate grooves in the outer periphery of the cylindrical projection. The sleeve at each side of the faucet body is held onto the body by means of a large headed bolt 83 that is threaded into an appropriately tapped bore and sealed by means of an O-ring 85.

As shown in FIGURE 10, the projection at the left, which is on the hot water side, has a central passageway 86 therethrough and the cold water projection has a central passageway 87 therethrough, these two passageways opening into a central vertical bore 88 that extends through the body of the faucet spout portion 15 of the head 11. This vertical bore is in two different diameters providing a shoulder 89 that is adjacent to the upper part of the spout portion of the head and this vertical bore provides a seat for a barrel valve 90. The vertical bore through the center of the faucet portion of the head preferably has an aerator 91 at the exit thereof, this aerator threading into the lower end of the spout portion 15 of the head in a conventional manner. Barrel valve has a lower portion 92 that is a slip fit relation with the vertical bore 88 through the spout portion 15 of the head, this lower portion being of a larger diameter than the upper portion that extends beyond the shoulder 89 and into the knob portion 14 of the head. The upper portion of the barrel valve comprises a stem 93 having a flat 94 thereon that receives a set screw 95 threaded through the knob portion of the head to lock the barrel valve in place. The lower portion 92 of the barrel valve has a vertical passageway therethrough identified by the numeral 96 and this passageway is open to a V-shaped slot 97 cut diametrically through the lower portion of the barrel valve. This V-shaped slot is in the rear portion only of the barrel valve. A stop pin 98 is provided that is seated within the spout portion of the faucet and extends into an arcuate groove 99 in the knob to limit the movement of the knob portion of the head with respect to the spout portion of the head. Groove 99 extends through approximately and therefore, limits the movement of the control knob portion of the head to a position in which it can be turned full left to full right.

Referring now to FIGURES 15 through 17, it may be seen that when the V-shaped slot 97 is arranged such that when its sides are open equally to the hot and cold

water inlet lines

12 and 13 respectively, that equal mixtures of hot and cold will be discharged from the faucet spout, this arrangement of the various parts appears in FIGURE 15. As shown in FIGURE 16, when the faucet knob is rotated toward the cold water line 12, more cold water than hot is permitted to flow into the cross slot 97 and out the faucet, and, as shown in FIGURE 17, when the knob is rotated to the right to the limit as determined by the stop pin 98, the cross slot 97 is completely open to the cold water line 12 to the exclusion of any hot water. It can be seen therefore, that by rotating the control knob portion 14 of the head about an axis D which is in a plane common to the vertical axis A about which the base is adapted to rotate, that a temperature control is provided.

It may be seen, therefore, that three controls of the faucet can be accomplished by grasping the knob 14. The first of these is the On-Off or volume control accomplished by raising and lowering the head which means pivoting the base about its horizontal axis B. The second is in moving the position of the head relative to the base by swinging the base about its vertical axis A, for example, in moving the faucet spout 15 from one part of a double bowl sink to the other, as shown in FIGURE 1. The third control described to this point is the control of the temperature of the water issuing from the spout, accomplished by rotating the knob portion 14 of the head about its vertical axis D. There is also another control that is unique with this faucet and that is best exemplified by a comparison of FIGURES l2 and 13 of the drawings. It should be noted that the flared port 80 extends through a limited number of degrees of the diameter of the cylindrical projection 77 for the hot side of the faucet and 78 for the cold side of the faucet, and that these flared ports are arranged relative to the respective ports 79--79, such that the flow of water issuing from the faucet spout diminishes and finally turns Off as the spout is directed toward the rim of the sink bowl.

It should be observed at this point that the faucet of this invention can be utilized to Wash down any portion of a sink bowl. It should also be observed that this can be done by grasping the control knob 14 by one hand. It can also be seen that the volume of water is under the control of a persons hand by raising and lowering the control head, that the temperature of the water issuing from the water spout is under the control of the rotation of the control knob 14, that the Water cannot be directed over the rim of the bowl.

There is one other control that can be utilized with the faucet of this invention, as best exemplified by FIGURES 3 and 14. A comparatively small port 100 is provided in both of the

cylindrical projections

77 and 78 at a point diametrically opposite the flared ports 80-80, such that the spout 15 may be turned into a vertical position and have a small amount of water issued from the spout. This provides a drinking fountain.

In summary, attention is now directed to FIGURE 2 wherein four axes are identified. Axis A, as identified in this figure, is the vertical axis about which the whole faucet is adapted to be swung from side to side. Axis B is the horizontal axis about which the head of the faucet is adapted to be raised and lowered. Axis C is one about which the head of the faucet is adapted to be rotated for directing the flow of water from the faucet and also for diminishing the flow as it approaches the rim of the sink bOiWl. Rotation about axis C of the head into the position shown in FIGURE 3 creates a drinking fountain. Axis D is the axis about which the knob portion of the faucet is turned to control the temperature of the vvater issuing from the faucet.

An added advantage to the faucet of this invention is that it is not necessary to provide a spray of the type that is used in association with many of the kitchen sinks now on the market. In order to provide a sink spray, it is now necessary to have a diverter valve in the faucet, which di-verter valve is exposed to the water that is flowing through the faucet at all times. There are many places where these diverter valves become ineffective within a matter of months because of the limiting conditions of the water. These sprays or sprayheads further have been connected to the water supply through a length of rubber hose; in many cases these rubber hoses have split or have become disconnected from their ends and have caused much damage through leakage. With the faucet of this invention, it is not necessary to provide such sprays, inasmuch as water flowing from the faucet of this invention can be directed into any section of a sink bowl.
