DRIPLFfiS FAUCET.

Specification of. Letters Patent.

Patented Nov. I5, 1192i.

Application filed December 27, 1920. Serial No. 433,167.

The object of the invention is to provide a practical and efiicient form of construction for a non-leaking valve, for the faucet or cook of'a draft tube, and which is equally well adapted for drawing hot or cold liquids or gases, or .for drawing liquids containing any solid substance as a sediment" 'or grounds, which by remaining upon the valve seat would make it impossible to completely close the valve in the faucet.

To avoid the disadvantages found in the use of a faucet that will not close tightly under all conditions, and from which the liquid is always dripping, I have employed the multiple form of valve and operating means therefor, and the mode of construction and combination and the arrangement of parts, hereinafter described, is shown in the accompanying drawings, and specifically pointed out in the claims.

In the accompanying drawings Figure 1, is a vertical central section of the device, showing the device open. Fig. 2, is a bottom plan thereof. Fig. 3, is a vertical section showing the valve closed.

In these figures, the valve is illustrated in connection with its use in a faucet adapted for drawing a liquid such as coffee, and in which the valve is operated by means of a lever, that is' actuated by means of the receptacle or container, such as the mug, or saucer for example when the mug or saucer is passed underneath the spout of the faucet, in the act of drawing the liquid from a reservoir, to place it in a position to be filled therefrom.

In these figures, A, is the outlet opening of a draft tube, from which the liquid is drawn; B, is the tube through which the liquid passes to the valve; C, is the valve chamber, comprising an enlargement of the tube B, closely adjoining the outlet opening A. i

In this chamber are positioned a multiple number of horizontal partitions having valve seats D, E, and F, respectively, and having a common vertical axis, and on these seats, a corresponding number of valves are seated, G, H, and I, respectively.

These seats and valves are successively smaller as they near the outlet opening A, to permlt of their introduction in the casing.

These valves are provided with vertical stems, N, O, and P, respectively, which are guided in corresponding openlngs W', W and W. The upper openin W, is made in a removable cap or plug in the wall of the draft tube.

The openings W, W, are formed in the upper valves themselves.

in the casin beneath the lower valve seat,'

and arm I provided with a slot M, in

which a link .or thrust member L, is pivoted. This member I, passes through a vertical bearing V, in the casing, and engages the lower valve and raises first the lower valve, and as the valve stems in turn engage with the valves above, raises in succession the valves above.

The valves are made independent in their movements to a predetermined amount, by leaving spaces above the stems in the open- 1ngs W, W, and W, when the valves are closed. The total amount of these spaces will be equal to the total amount that the lower Valve must be raised.

When all spaces above the valve stems are closed, the valves move simultaneously, as one unitary structure.

In this device, if grains of sediment such as coffee grounds or other sediment should lodge on any one valve seat and prevent it from completely closing, it would not prevent the other valves from acting independ ently to close on their seats, or if any two seats should become leaky from wear or from the lodging of sediment thereon, the third valve and seat would still operate to close their opening completely.

Springs Z, Z, and Z serve to close the erated by means of receptacles of different the lever B, is provided with a soft bumper strip -S, formed of felt or rubber which is preferably inserted in a groove or slot, T, in its engaging face.

To enable each valve to tilt upon itsv seat independently of the others if a grain of a sediment should lodge upon its seat. Each opening W, and the opening W are tapered or widened at their lower ends, to permit lateral movement of the stems.

Having described the invention what I claim as new and desire tosecure by Letters Patent is:

ll In a non-leaking valve mechanism for a faucet, in combinatlon, a dispensing tube having a delivery opening, a vertical enlargement thereon forming a valve chamber,

a multiple number of valve seats in said chamber, arranged therein at different levels, a corresponding number of valves for said seats, said valves provided with valve stems,

guide means for the stems of. the lower valves in the valves above, and guide means for the upper valve in the wall of said tube, and means engageable by the utensil employed in drawing the fluid from said valve, for raising the lower valve, and thereby, in succession the valves above, one after the other, when all of said valves are raised together above their seats, and'automatically acting means for returning said valves to their seats.

2. In a non-leaking valve mechanism, in combination with a draft tube, provided with an outlet opening, said tube enlarged intermediate of its ends to'provide a vertical valve chamber, spaced horizontalpartitions in said chamber, said partitions provided with alined valve seats, corresponding valves for said sea-ts, axial valve stems for said valves, the upper valve stem provided with a vertical guide in the wall of said draft tube, and the remaining valve stems each provided with a vertical guide in the next adjacent valve above, each lower valve stem when raised engageable with and operating to raise the valve above, and each lower stem having a predetermined amount of vertical movement before engaging the valve above,

and means for raising the lower valve, and thereby in successlon raising the other valves.

3. In a dripless valve mechanism in combination, a draft tube, a vertical valve chamber therein, a multiple number of spaced valve seats in said chamber, arranged at different levels, and valves therefor, stems for said valves, the upper valves provided with guide openings, in which the stems of the lower valves are guided, and a separate guide opening in said tube forthe stem of the upper valve, said guide openings permitting a predetermined amount of independent movement of each valve above its seat,'an arm pivoted in said chamber, means for operatively connecting said arm with said lower valve, and an operating-lever for said arm.

4. Acomposite valve mechanism including in combination therein, a dispensing tube having a delivery opening an enlargement thereon forming a valve chamber, independently movable valve parts seated in said chamber, one part being actuated by the one preceding and in turn actuating the part succeeding, so that the various parts close successively. and are open successively but in reverse order, a transversely and pivotally mounted actuating member in said chamber and adjacent to one of thesaid valve parts,

chamber wall, and means outside said wall 3 adapted to-be actuated by thrust of the receptacle to be filled from said opening for rocking said member.

6. In an automatic valve mechanism, in

combination, a valve chamber having inlet and outlet openings, spaced valve seats in said valve chamber, and independently movable valves seated thereon, said valves and valves seated being of different sizes and arranged in vertical and axial alinement, the seats and valve being successively smaller as they near the outlet opening, the said valves being normally out of operative contact with each other, each valve; when raised serving to raise in turn the next larger valve, and means for operating the smaller valve.

7. In a valve mechanism, a valve chamber a multiple number of tapered valve seats vertically spaced apart, therein, a valve resting upon each tapered seat, each valve provided with a vertical stem, the stem of the lower valve having a limited vertical movement in the adjacent valve, and adapted to engage and raise the adjacent valve in turn when said lower valve is raised from its seat,

answer and manually operated mechanism for raising said lower valve from its seat, said valve chamber provided with a tubular guide openin in its wall in which the stem of the upper va ve is movably secured.

8. In a faucet in combination, a draft tube having a horizontal portion and a vertical portion, a valve chamber in said vertical portion, said valve chamber terminating in a discharge nozzle, upper and lower valves in said. valve chamber, tapered seats for said.

valves, each valve provided with a vertical stem extending above the valve, and the lower valve, provided with a vertical stem extending below said valve, a guide therefor in said chamber below said lower valve, a guide opening for the upper stem of said lower valve in the valve above, and a guide opening for the valve stem of said upper valve in the upper horizontal wall of said draft tube.

Intestimony whereof, I hereunto set my hand this 23 day of December, 1920.
