Patented Nov. 21, 1933 UNITED STATES PATENT OFFICE FAUCET Louis Piro, Philadelphia, Pa.

Application June 15, 1932. 'Serial No. 617,365 1 Claim. 7 (01. 210-78) My invention relates to a novel and a useful faucet which is provided with a self-cleaning internal strainer interposed between the intake pipe and the discharge outlet of the faucet in such a way that the water passes through a suitable screen, deposits its debris and sediment thereon, and flushes clean the straining element at all times while flowing.

My invention further relates to a faucet of this character wherein the discharge outlet or nozzle member is of the rotatable and easily detachable type to permit of ready removal and reinsertion of the screen for repair or replacement.

My invention still further relates to a faucet wherein an easily removable plunger permits the escape of the accumulated debris and sediment through a by-pass under the pressure of the intake water.

My invention relates furthermore to a faucet wherein an easily removable tensioned plunger automatically permits the escape of the ac-' cumulated debris through a by-pass when the strainer becomes clogged by the action of the water under pressure forcing the plunger from its seat.

My invention relates also to several other outstanding features of construction and convenience and all are hereinafter described and claimed in connection with the accompanying drawing in which:

Figure 1 is a top view of a faucet embodying my invention.

Figure 2 represents a section on line 22 of Figure 1.

Figure 3 is a view showing details of construction of the strainer,

Referring to the drawing, in which like reference characters indicate like parts, 1 represents an intake pipe of any suitable construction for delivering water, said pipe being connected to a source of water in any desirable manner. Intake 1 discharges the water into chamber 2 through the beveled orifice 3 of the said intake. Orifice 3 is carefully machined to serve as a seat for the plunger valve 4 suitably designed to accommodate itself closely to said orifice. Said plunger valve 4 is rigidly or integrally attached to the screw 5, said screw terminating in a stem 6 to which is attached the lever or handle '7. The stem 6 passes tightly through the cap fitting 7, which threadedly engages the casing 8, the inner surface of which is threaded to receive tightly the screw 5. The stem 6 and screw 5 are designed to engage their separate fittings tightly or cleaning.

in order to prevent breakage of water past the stem 6. To the forward end of the casing 8 is threadedly engaged the discharge outlet 9 which is held securely in position by means of the lock nut 10. The inner end of the outlet is threadedfii) to engage the ferrule 11 over the inner end of which is spread a screen 12 of any desirable mesh. At the lower end of the casing 8 and formed by the intake 1 and the bottom of said casing is the by-pass 13 which is ordinarily closed :6

'by the abutment of the plunger 14 against the beveled shoulder 15. The plunger 14 is carried by the stem 17 which passes through the threaded fitting 18 and which is provided with the The fitting 18 threadedly engages an ;.70

The operation of my novel faucet is described J5 briefly as follows. When the lever or handle '7 is rotated sufiiciently the screw 5 and the plunger valve 4 are lifted from the seat 3 permitting the water entering the intake 1 to flow into chamber 2. pinges against the strainer 12 which separates the insoluble materials and prevents them from further onward movement and permits the clarified water to pass through its mesh and thence through the discharge outlet 9. for the most part collects in the by-pass 13 although some may persistently adhere to the strainer 12 in spite of the intermittent flow of water through and the impact of water against it. To clean the strainer 12 and to purge the e!) I by-pass 13 the knob 19 is pulled'outwardly, thus withdrawing the stem 17 and the valve 14 to disengage the latter from its seat 15, thus establishing communication between the passage 13 and the outlet 20.

spring 21 serves to return the valve 14 back to 7 its seat 15 when the pulling action on the knob 19 is discontinued. It is to be observed also that inexceptional cases when the strainer 12 becomes The water with its debris and sediment im-QO The sediment 7 The pressure of the helical 05 excessively clogged with debris the pressure of the water in the chamber 2 forces back the plunger valve 14 against the action of the spring 21 and carries the debris through the by-pass 13 and the water outlet 20.

In order that the strainer 12 can be more thoroughly cleansed the lock nut 10 can be loosened and the discharge outlet 9 can be withdrawn from the casing 8, thus permitting of an easy removal of the strainer 12 for repair, replacement position, a ferrule threaded into the inner end of said outlet, a screen carried by said ferrule to filter the water passing from said chamber to said outlet, a by-pass leading from said chamber to a waste outlet, and a removable spring tensioned valve for normally closing said by-pass, said valve being operable from without and being adapted to be actuated by the pressure of the water within said chamber to establish communication betweensaid by-pass and said waste outlet.
