E. E. MURPHY. DISPENSING FAUCET. APPLIUATION FILED 1720.14, 190s.
Patented June r7,1910.
l l l i l UNITED STATES PATEN T FFTQF.
EDWARD .'E. MURPHY, OF WINCHESTER, MASSACHUSETTS, ASSIGNOR TO PUFFER MANUFACTURING COMPANY, A CORPORATION OF MAINE.
l State of Massachusetts, have invented an Improvement in Dispensing-Faucets, of which the following description, in connection with the accompanying drawings, is a specilication, like letters on the drawings representing like parts.
The present invention relates to a dispensing faucet of the kind commonly used for dispensing carbonated water and thel like, in which it is desirable at times to have a comparatively free flow of the water, and
atn other times to have a restricted flow, so that a fine stream will issue with considerable force.
The invention is embodied in a construction in which a single movable valve member is employed having an actuating device, the arrangement being such that the large orilice or the small orifice may be opened by moving the actuating device to two different positions.
In accordance with the invention, the faucet is provided with a main nozzle hav ing a large orifice, this nozzle being at the end of a valve chamber provided with an inlet for the liquid. Vithin the nozzle and movable in the valve chamber is a tubular valve member suitably packed at the ends and provided with differently located lateral inlets, so that the longitudinal movement of the said valve member will open or close the said inlets selectively. The valve member is also provided with a small nozzle which communicates with one inlet or set of inlets when the others are closed, -so that when the valve is in this position the liquid will be dispensed in a fine stream. The faucet is so arranged that when the actuating member is in an intermediate position the faucet will be closed, and the line stream or the copious stream may be obtained by moving the actuating member in opposite directions from the closed position.
Figure l is a vertical section of a dispensing faucet embodying the invention, the actuating member being shown in elevation and in its normal or closed position; Fig. 2 is a similar view showing the valve moved to the position in which the copious stream may be supplied; Fig. 3 is a similar view Specification of Letters Patent.

showing the valve moved to the opposite position to dispense the line stream.
In the construction shown, the valve casing a is cylindrical in form, and provided with a lateral inlet a2, and an arm or supporting member a projecting upward to receive and support an actuating handle or lever o which is pivoted to the support a3 at a4. The valve chamber a is closed at the top by means of a packing gland a5 through which extends the valve member c, the lower end of the valve chamber being provided with a nozzle a, which is of sufficient size to discharge the copious stream. The valve member c is shown as a longitudinally movable cylindrical member pivotally connected at c2 with the handle Z), so that a rocking movement of said handle upon its pivotal support a* will produce a longitudinal movement of the valve member c in one direction or the other. Vithin the valve chamber a the valve member c is provided with cup leather packings c7 and as above and below, the upper cup leather being held in position by the gland a5, and the lower one by the nozzle c6.
The valve member c is normally held in the closed position, that is to say, the position shown in Fig. 1, by means of a spiral spring cl which seats at opposite ends upon flanged collars cl2 surrounding the lower portion of the valve member c, and being located between ixed shoulders c3 and c4 upon said valve member. The upper of said flanged collars Z2 also bears against a retaining collar a9 which holds the lower cup leather as in position, while the lower flanged collar Z2 bears against an annular shoulder am formed in the nozzle member a6. The spring d, therefore, tends to spread the collars (Z2 and to hold them in the position shown in Fig. l, in which they are separated by a distance substantially equal to the distance between the shoulders c3 and ci of. the valve member c. By this construction, as will be seen from Figs. 2 and 3, a movement of the handle b in either direction to move the valve member c up or down will compress the spring cZ, the tendency of which in either case, when released, will be to restore the valve member to the closed position shown in Fig. l. The inlet a2 to the valve casing a allows the liquid to lill the spacearound the valve member c between the cup leather packings f and as, and the outlet from the valve casing is through the valve member c which is bored to form a main longitudinal passage c with which' communication is made from the valve chamber through a series of lateral inlets 0G formed in the wall of the valve niember c.
The restiicted outlet nozzle c consists of a tube connected with the valve member c, being herein shown as threaded in the upper portion of the bore in said valve member, so as to close the space therein above the ports c6.
Communication is opened with the nozzle c through a latei'al inlet port c2 shown as a small opening made in the wall of the valve member c above the nozzle c. The lateral ports above described, when the valve is in its normal closed posit-ioii, are all closed by the cup leather packiiigs, a longitudinal movement of the valve member, however, in one direction or the other bringing o-iie port or the other past the cup leather packing and into communication with the valve chamber. By moving the valve handle I) to the right, as shown in Fig. 9., the valve niember c is lifted, so that the ports c are brought above the lower cup leather as, thus allowing the liquid to flow from the valve casing into the main orifice c5 through the valve meinber c, and thence out through the large nozzle a6. The liquid passes down through the valve member, around the small nozzle member e, and in order to break up the stream, the said nozzle member c is shown provided with a cup e3 which extends toward the walls of the nozzle member a, so that the liquid falls in said cup and overflows around the side thereof, thus producing a stream of considerable size, but with comparatively small velocity of flow.
The movement of the handle I) to the left, as shown in F ig. 3, produces a downward movement of the valve member c, carrying the port e2 below the upper cup leather al, so that the said port is in communication with the valve casing admitting the liquid to the outlet nozzle e.
In the construction shown, only a single port e2 is employed, and that of comparatively sinall capacity, so that the flow of liquid is largely throttled, causing a line stream to pass through the nozzle e with considerable velocity.
As previously stated, the movement of the handle b in either direction compresses the spring CZ, so that when the handle is released tlie faucet will return to its normal closed position, shown in Fig. 1.
1. In a dispensing faucet, a valve casing provided with a main outlet nozzle; a tubular valve member longitudinally movable in said casing and packed above and below the lateral inlet to said casing and constituting a nozzle; a supplemental nozzle located within said valve member, said valve member being' provided with separate ports leading respectively to said supplemental nozzle member and to the space around the same; and means for producing a longitudinal movement of said member to uncover either of said ports.
2. The combination with a valve casing provided with a lateral inlet and cup leather packings above and below said inlet; of a tubular valve member passing through said casing and through said cup leather packiiigs, said valve member constituting a nozzle, and being provided with lateral inlet ports, said ports normally being closed by contact with the cup leather packings; a
`supplemental nozzle within and concentric `with said valve member, one of the inlet ports of the valve member communicating with the supplemental nozzle; and means for producing a longitudinal movement of said valve member to uncover either of said ports, as desired.
3. The combination with a valve casing` sets of ports leading through the wall of said member, said ports being normally closed by packing within the casing; separate nozzles supplied respectively by said ports; means for moving said valve member in either direction to uncover either of said ports to the exclusion of the other; and a spring adapted to be compressed by a movement of said valve member in either direction.
f1. The combination with a valve casing provided with a lateral inlet; of a tubular valve extending through said casing and provided with lateral inlets in different vertical planes; cup leather packings at opposite ends of said casing normally covering said inlets respectively; a supplemental restricted nozzle member consisting of a tube contained in said tubular valve, the upper end of said member separa-ting said inlets, and the member itself being supplied through the upper inlet; and means for producing a longitudinal movement of said tubular valve member to uncover one of said ports or the other according to the direction of movement.
In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
