unirse stares JOHN JOSEPH MAHONEY, OF TAUNTON, MASSACHUSETTS.

DOUBLE-ACTING FAUCET.

Application filed August 2, 1921.

To all 'whom 'it may concern Be it known that l, JOHN J. MAHONEY, a citizen of the United States, residing at Taunton, in the county of Bristol and State of Massachusetts, have invented certain new and useful lmprovements in Double-Acting Faucets; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improve ments in double acting faucets which are self-closed for use in the distribution of hot and cold water, and the invention has for an object to provide a simple, compact and inexpensive construction of faucet with 'a double acting valve structure operable by a single handle and controlling the flow of both hot and cold water, with devices to keep the valves in an open or partially open position until manually released, whereupon the device is restored to the initial closed position. V

Another object ofthe invention resides in the provision of a faucet of this character, in which independent water boxes are provided in communication individually with sources of hot and cold water, wherein independently movable valves are provided to control the flow of water to a common nozzle or spout.

rlhe invention will be more fully understood after reference to the Vaccompanying drawings, in which like parts are indicated by similar reference symbols throughout the several views, and in which Figure 1 is a view in side elevation of an apparatus constructed according to the present invention.

Figure 2 is a vertical sectional view therethrough.

Figure 3 is a sectional view taken at right angles to Figure 2; and

Figure 4 is a'sectional view taken on the line 4-4 in Figure 1.

Referring more particularly to the drawings, 1 designates a nozzle or spout which communicates in common with the two water boxes 2 and 3. A pipe 4 in communication with a source of cold water leads to the water box 2, while the companion water box 3 is in connection with a source of hot water supply by a pipe 5.

11 of compressible material which are.A

adapted to seat tightly against the raised valve seats 12 and 13 on the interior bottom Compressible portions of the water boxes. valve disks and 11 are held on the plungers 8 and 9 as by the screws 14, but, of course, other suitable fastening means may be substituted. The valve disks 10 and 11 may be thus disconnected from the plungers when worn, and replaced.

Cylinders or sockets 15 and 16 depend from the top plates 17 and 18 of thewater boxes, and are provided to slidably receive the plungers 3 and 9 which reciprocate in a substantially vertical direction, they being urged normally downward by coil springs 19 and 20, wound about reduced stems 21 and 22 which extend upwardly from the plungers and form shoulders therewith, upon which the lower ends of the springs rest.

Links 23 and 24 connect the upper proljecting ends of the stems 21 and 22 with curved t ` ms 25 and 26, adapted to be oper-` ated separately by a common centrally disposed handle 27.

As more particularly shown in Fig. 3, the handle 27 is made with a bearing sleeve 28 rotatable freely upon a rod'or shaft 29 which is preferably in the form of a -screw having threads 30 at one end, screwed into a threaded lug 31, secured-to the top of the device and having its head 32 disposed on the outside of a second stationary and perforated lug 33.V rlfhe bearing sleeve 28 is provided with right angularly turned lugs 34 and 35 which are adapted to engage pins 3G and 37 on the bearing sleeves 38 and 39, respectively, of the curved arms 25 and 26. Vlhis construction is most plainly seen in Fig. 4. The arms are upwardly curved where they connect with the links 23 and 24 to adapt them to swing down in the closing movement of the valve, and to lift freely in raising the valves. Moreover, thev outer overhanging ends of the arms 25 and 26 lie beyond the sides of the water boxes and are turned down to a low point in order to connect with bolts or catches 40 and 41 which have a swinging movement about the arms and are adapted to engage with rack' teeth 42 and ii-23 carried at the sides of the waterboxes.

In the use of the device cold water from the pipe t constantly occupies the water box 2, while hot water received through the opposite pipe 5 is contained in theAadjaCent` water box 3, but neither supply of water is permitted to descend into the faucet l because of the initially closed position of the two valves. Y

The springs l9'and 2O are responsible for this closed position, and they restore the val-ves: to their seats after-'each opening' thereby causing the lugBLt'to ride downward against'the pin 36 and raise the arm 26.'

I/Vith' the arm, the valve plunger 9 is also lifted and hot water may then descend through the ports 7 and issue from the faucet l. The engagement of the pawl or'Y catch 41 with the rack teeth i3 will'pr'event the immediate return of the valve to its'seat by Y reason of the influence ofthe spring 20, ant

consequently the device may be kept V in this position without the-continued attendance of the operator. `When a sufficient supply of water has'been had, the catch il is released and the valve 9 automatically closes.A By
