SAFETY-FAUGET.

To all whom it may concern:

Be it known that l, GEORGE A. HIDDEN, a citizen ofthe United States, residing at Coronado, in the county of San Diego and State of California, have invented new and useful Improvements in Safety-Faucets, of which the following is a specification.

This invention relates to a faucet and particularly pertains to a combined safety valve and faucet.

It often occurs that domestic Water heaters will become overheated and the accumulated steam pressure within the circulating System, reaches a temperature which causes It is the principal object of this invention to provide a water faucet through which the heated water may be drawn from said heating system and within which is incorporated a safety valve adapted to. relieve the steam and water when in excess of a predetermined pressure and thereby positively and automatically preventing an explosion within the system.

Another object of this invention is to provide a, device of the above character which is compact in its design and incorporates both of said valves, the cut-off and safety valves, within a single member.

Another object of this invention is to provide an operating member for said valve which is so positioned as to. permit actuation of the valve member without moving the actuating member, or being affected thereby when the pressure within the supply pipe is to be relieved.

It is a further object of this invention to provide a valve of the above class which is composed of few parts, may be easily manufactured, readily assembled, and will act positively without danger of becoming inoperative.

Other objects will appear hereinafter.

The invention is illustrated, by way of example, in the accompanying drawings in which:

Figure 1 is a View in longitudinal section illustrating the complete faucet and disclosing in a detailed manner the co-relation of the vital elements thereof.

Fig. 2 is a view in transverse section as seen on the line 2-2 of Fig. 1 illustrating the valve stem supporting member.

. Fig. 3 is a view in elevation as indicated by the arrows 8-3 of Fig. 1 and particu- Specification of Letters Patent.

larly discloses the eccentric pin by which the valve is manually actuated.

Referring more particularly to the drawings, 10 indicates the threaded end of a water supply pipe adapted to receive the sleeve 11 which forms a part of the faucet 12'. The sleeve 11 is formed with an enlarged main bore 13 in communication with a reduced bore 14 within which shank 15 of a valve 16 is reciprocably mounted. The shank positioned within the small bore 14 is cylindrical and its sides are formed with flutes 1 7 through whichv water may pass into the enlarged bore, or chamber 13 of the sleeve when the valve 16 is relieved from its seat. The outer end of the sleeve 11- is internally threaded to receive the threaded end of the faucet housing 18. The housing 18 is formed with a downwardly extending spigot 19 and an upwardly extending valve actuating shaft housing 20, both of which have openings communicating with a central chamber 21 extending throughout the length of the main portion of the housing. The opening through the extension consists of a circular lower portion '22 and a :t'rusto-conically shaped upper portion 23. adapted to receive an inverted frusto-conical stem packing member 24 which surrounds the stem 25. A pair of packing washers 26, are also mounted within this bore and beneath the conical packing portion 24.. These members surround a cylindrical extension 27 of the shaft on the end of which an eccentric pin 28 is formed. This pin extends downwardly into the chamber 21 of the. faucet and is adapted to bear against the faced an actuating collar 29 fixed to the valve stem 30. This stem extends longitudinally of the chamber-Q1 and also of the bore 13 in the sleeve 11, its one end bearing against the top of the valve member 16 and its opposite end slidably positioned within a re cess 81 formed in a screw-plug 32. This plug closes the outwardly extending end of the valve housing. actuating collar 29 will at all times bear against the eccentric pin 28, a helical expansion spring 33 is interposed between the collar and the plug 32. In this manner yieldab-ly supporting the collar when, the stem 25 is rotated by its handle 34. The valve stem is further supported by a supporting collar 36 interposed between the ac- In order that the r t'uating collar 29 and the valve 16. This collar is positioned upon the stem and 15 of a diameter to permit it to reciprocate within the chamber 21 of the valve housing. In order to permit free circulation of water around. the collar, a series of flutes 37 are formed longitudinally thereof, as. particularly shown in Fig. 2 of the drawings.

In operation, the faucet is assembled as shown in Fig. 1 and thereafter mounted within the end of the pipel f. This pipe, in turn, is connected with a heating system from which water is delivered to the faucet. Under normal conditions rotation of the stem25 will act through the medium of the eccentric pin 28 to move the actuating collar 29. Movement of this collar will simultaneously move the valve stem 30 in the direction indicated by the arrow a-. This will relieve the pressure of the stem and its spring 33 from the end of the valve 16 and causethe pressure of the water within the pipe 14 to force the valve member into the bore 13'of the sleeve 11. This will act to permit the liquid to pass through the flutes 17 in the shank of the valve and thereafter enter the bore 18 of the sleeve, from which point it will pass through the chamber 21 of the faucet housing and out through the spigot opening 19. A reversal movement of the handle 3% will, of course, cause the spring 33 to force the valve member 16 back upon its seat and cut off the water supply.

lVhen an abnormal pressure exists within the pipe 1 1 it will act upon the end of the valve shank 15 and the exposed portion of the valve member 16 against the pressure of the spring 33. When this force becomes sufficient to overcome the pressure of the spring 33, the valve member will be relieved from its seat and the steam and water allowed to pass out through the spigot, thus providing an automatically acting safety valve which is incorporated within the fancet construction and which includes the service valve as one of its elements.

It will thus be seen that the device here disclosed is formed of few parts which are not liable to wear and which act in a positive manner to permit a liquid to be drawn from a pipe and also to permit it to be vented therefrom under excessive pressures.

While I have shown the preferred construction of my safety faucet as now known to me, it will be understood that various changes in the combination, construction and arrangement of parts may be made by those skilled in the art without departing from the spirit of my invention.

I claim: v

1. A faucet comprising a sleeve adapted to be connected with a water supply pipe, the bore of said sleeve being reduced at the connecting end, a slidable valve member mounted within the reduced portion of the bore and adapted to overlap its edges at its inner end, a faucet housing detachably secured to the free end of the sleeve and in communication therewith, a plunger extending longitudinally of the faucet housing and the sleeve, shoulders formed upon said plunger to hold it centrally of the housing and sleeve, a spring adapted to hold one end of the plunger against the end of the valve memher, and means for opposing the expansion of the spring and relieving the valve from the end of the plunger, whereby the water pressure within the pipe will move the valve member and permit water to flow .through the faucet housing.

2. A faucet comprising a valve sleeve adapted to screw into a water supply pipe at one end, a faucet housing screwed into the opposite end of said valve sleeve, said faucet having a central cylindrical opening extending as a continuation of the central opening in the valve sleeve, a shoulder in said valve sleeve, a valve port extending through one end of the sleeve, a cylindrical valve memher having a portion slidably positioned within said port and having an enlarged end portion normally bearing upon said shoulder, flutes formed longitudinally along the sides of the valve member within the port, a plunger rod abutting against the inner end of the valve member and extending longitudinally through the central openings of the sleeve and housing, a spider formed around the plunger rod and adapted to hold the plunger centrally and permit water to pass thereby, a fixed shoulder formed upon the plunger, an expansion coil spring bearing against said fixed shoulder and holding the end of the plunger rod against the valve member, whereby the valve may be moved from its seat under the pressure within the pipe, an eccentric pin adapted to be brought to bear against said fixed shoulder to manually reciprocate the plunger rod in a direction to permit the valve to open under fluid pressure, and operating means for moving the eccentric pin.

3. A faucet comprising a valve sleeve adapted to screw into a water supply pipe at one end, a faucet housing screwed into the opposite end of said valve sleeve, said faucet having a central cylindrical opening extending as a continuation of the central opening in the valve sleeve, a shoulder in said valve sleeve, a valve port extending through one end of the sleeve, a cylindrical valve member having a portion slidably positioned within said port and having an enlarged end portion normally bearing upon said shoulder, flutes formed longitudinally along the sides of the valve member within the port, a plunger rod abutting against the inner end of the valve member and extending longitudinally through the central openings of the sleeve and housing, a spider formed around the plunger rod and adapted to hold the plunger centrally and permit Water to pass thereby, a fixed shoulder formed upon the plunger, an expansion coil spring bearing against said fixed shoulder and holding the end of the plunger rod against the valve member whereby the valve may be moved from its seat under the pressure Within the pipe, an eccentric pin adapted to be brought to bear against said fixed women of thin patent may be obtained for five cents each, by addressing the Commissioner shoulder to manually reciprocate the plunger rod in a direction to permit the valve to open under fluid pressure, operating means for moving the eccentric pin, and adjusting means for regulating the expansive force of the spring.

In testimony whereof I have signed my name to this specification.
