FAUCET.

Application filed February 4, 1916.

To all whom it may concern:

Be it known that I, CHAnLEs B. STILWELL, a citizen of the United States, residing at lVayne, in the county of Delaware and State of Pennsylvania, have invented certain Improvements in Faucets, of which the following is a specification.

My invention is designed to provide a simple and inexpensive faucet having improved means for relieving excessive pressures in fluid distributing systems, preventing wastage without necessity for the usual replacement of washers, and providing a structure that is practically permanent.

In hot water systems used in dwellings, for instance, it is frequently desirable to relieve excessive steam pressure which may result in leaks, ruptures or explosions, and it is an object of my invention to efiect the desired relief by means that can be depended upon to effect this function, without interfering with its convenient use for drawing water.

It will be understood that pressures due to reezing temperatures in exposed faucets are relieved by the same means.

The usual faucet is of such character that washers must be renewed, with some inconvenience and expense, at comparatively frequent intervals and the parts wear and rust out, due to hard usage and chemical action.

It is an object of my invention to provide a construction that will stand up under hard usage, that is not destructible by corrosion, that will not require the usual replacement of washers and that is composed of parts which are readily dissociated and assembled.

In the accompanying drawings, Figure 1 is a top plan view of a faucet embodying the invention; Fig. 2 is a similar view showing a second position of the same; Fig. 3 is a vertical section through the closed faucet with the parts in the relation shown in Fig. 1; Fig. 4 is a vertical section through the open faucet with the parts in the relation shown in Fig. 2; Fig. 5 is a sectional view taken on the line 55 of Fig. 3; Fig. 6 is a sectional view taken on the line 66 of Fig. 1; Fig. '7 is a sectional view taken on the line 77 of Fig. 4: Fig. 8 is a side elevation of the inlet with the body or shell of the faucet removed therefrom, and Fig. 9 is an elevation of the detached faucet body with the cap removed.

The improvements, in the form. thereof Specification of Letters Patent.

Serial No. 76,081.

illustrated, are comprised in a hollow body or shell 1 having open ends, with a circular lateral aperture 1; top threads 1" and oppositely disposed lugs 1 A conduit 1 is provided with an elbow or bend 1 which is passed through the aperture l and disposed upwardly in the body, with an angular bearing 1 which fits the aperture 1., and with a lug l through which and the body is passed a pin 1", the pin securing the parts 1 and 1" together.

A hood valve 2 is provided with a vertical slot 2" adapted to run on a guide lug l of the part 1 and with a recess 2 adapted for seating packing 9/, which is designed for closing the outlet at the top of the part 1 A hood 3, provided with the internal threads 3 for engaging the external threads lf on the top of the body, is movable vertically on the body thereby.

A dished or bent spring 5 is disposed within the top of the hood 3, against which and the lug 2 on the hood valve 2 it bears; the spring tending to hold the valve down with the packing 2 on the top of the part 1 and permitting this hood to rise if subjected to excess pressure in the conduit 1, when the hood 3 is screwed down.

A handle 9 is fixed on a split collar 10 provided with lugs 10 through which passes a screw 11, whereby the collar is adjustably clamped on the hood 3, a lug 9' being fixed to the collar and adapted to engage the lugs 1 for limiting the movement of this hood.

The parts are readily dissociated by 1oosening the screw 11, unscrewing the hood 3 and removing the pin 1 when the part 1 can be detached. By suitably positioning the hood 3 on the body threads 1 before tightening the collar 10 on the hood, the maximum pressure of the washer 2 against the end of the conduit section 1 when the handle 9 is turned to the closed position with its lug 9 in engagement with a lug 1, can be proportioned to a predetermined pressure of fluid in the conduit, whereby the valve is unseated upon the occurrence of excess pressure and the life of the washer prolonged.

In operation, water is drawn or stopped by turning the handle 9, which elevates or lowers the valve 2, the water pressure in the conduit 1 lifting the valve when the hood 3 is elevated, and the spring 5 seating the valve when the hood 3 is down.

In case of excess pressure in the conduit 1 when the hood 3 is down, the valve 2 is controlling said inlet, means comprising a.

spring and a movable head for controlling said valve, said spring permitting the closed valve to open when subject to abnormal pressure, and means for adjusting the maximum pressure of said valve.

2. A faucet comprising a threaded body, a conduit having an outlet, a valve for controlling said outlet, means comprising a rotary head threaded on said body for operating said valve, and means for varying the maximum pressure of said valve on said outlet.

7 Copies 01' this patent may be obtained for 3. A faucet comprising a threaded body, a

conduit having an outlet, a valve for controlling said outlet, means comprising a rotary head threaded on said body and a spring disposed between said head and valve for operating the latter, and means comprising a lug connected with said head and a lug connected with said body for limiting the movement of said head, one of said lugs being adjustable, whereby the maximum pres sure applicable to said valve through said head may be varied.

4. A faucet having a hollow body provided with a lateral aperture, a conduit having a section disposed in said aperture and a.

bent section containing an outlet disposed in said body, a pin engaging said conduit section within said body for holding said body and conduit together and a valve for controlling said outlet.

' In testimony whereof I have hereunto set my name this 7th day of October, 1915.
