FAUCET-NOZZLE.

Application filediMarch 8,

To all whom it may concern:

Be it known that I, ABRAM W. WHEATON, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in F aucet-Nozzles; and I 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, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

The present invention relates, generally, to improvements in faucets, particularly adapted for use upon oil and gasolene tank vehicles; and the invention relates, more particularly, to an improved self -closing faucet and detachable operating handle for manipulating the same. 7

The invention has for its principal object to provide a novel construction of self-closing faucet adapted to be manipulated by a .1 With said chamber or passage 2, and adapt novel detachable handle member constructed to cooperate with novel means connected with the faucet whereby the valve member.

- may be held open until the handle-member is detached from said means. The invention also provides a means for opening and holding open'the faucet to its full extent or capacity, or to an intermediate partial extent, as may be desired. i

.The invention has for a further object to provide a novel locking means for locking down the faucet valve upon its seat, so that the same is held in secured closed relation to the seat at all times until said locking means is released.

Other objects of the present invention, not at this-time more particularly enumerated, will be clearly understood'from the following detailed description of the same.

With the various objects of the invention in view, the same conslsts, primarily, in the novel self-closing faucet and detachable operating handle-member therefor hereinafter set forth; and the invention consists,

furthermore, in the novel arrangements and combinations of the various devices and parts, as well as in the details of the construction of the said parts, all of which will be more fully described in the following specification, and then finally embodied in the claims which are appended to and which Specification of Letters Patent.

form an essential part of the said speciiicatlon.

The invention is clearly illustrated in the accompanying drawings, in which z- Figure 1 is a vertical longitudinal section of the novel self-closing faucet showing the novel detachable handle member applied thereto in operative relation therewith.

Fig. 2 is a horizontal cross-section taken on line 22 in said Fig. 1.

Fig. 3 is a front end elevation of theupper portion of the novel faucet, the operating handle member being detached and removed therefrom.

Similar characters of reference are em.

ployed in all of the hereinabove described views to indicate corresponding parts.

Referringnow to the said drawings, the reference character 1 indicates the faucet body providing in its lower end the interior hamber or passage 2. Extending from the rear side of said faucet body is an internally screw-threaded extension 3 communicating ed to receive the threaded end ofthe outlet pipe of the tank vehicle (not shown), thus securing the faucet operatively thereto. Connected with the lower end of said faucetbodyllais a downwardly extending nozzle- "portion' 4, which is provided ,within said fauc%body with a valve seat-portion 5 upon wliic seats itself, when in closed position,

a vertically movable valve-member 6, upon which is secured a valve-washer 7 of suit able material. Connected with said valvemember 6 is an upwardly extending valve .stem 8. The said faucet-body 1 is provided, above said chamber or passage 2, with a transverse-horizontal partition or wall 9, having a' centrally disposedopen'ing forming a guideway 10 through which said valve stem 8 slidably extends. Said partitionor wall 9 is provided, at the upper end of said guideway 10, with an annulardepression forming a packingseat. 11, in which is arranged a suitable packing 12', adapted to embrace said valve stem 8, and thereby prevent leaking of any-fluid upward through said guideway 10. A perforate keeperplate 13, secured to the upper side of said partition or Wall 9, by screws 14, or other suitable fastening means, serves to retain said packing 12 against removal from said packing seat 11. Arranged about said valve stem 8, between said partition or wall 9 and washer 7 in closed or seated relation to the valve seat-portion 5.

Said faucet-body is provided, above said wall or partition 9 with an upwardly projecting-tubular extension 16, having at its upper extremity an externally threaded neck 17 adapted to receive a closing cap 18, which -is internally threaded to screw upon said neck 17. Said valve stem 8 projects upwardly into the space 19 inclosed by said extension 16 and the cap 18,- and is provided adjacent to its upper end with a transverse slot or receiving opening 20. Extending upwardly from the upper extremity of said valve stem 8 is a reduced extension 21 thereof, which is'slidably disposed for vertical movement in a guideway 21 provided in said closing cap 18. Formed in the front side of said tubular extension 16 is an opening-or hatchway 22, providing access to the valve stem 8 for the detachable operating handle member to be presently described. The lower end of said opening or hatchway 22 is formed to provide a fulcrum member 23, the purpose of which will presently appear. Pivoted to the exterior surfaceof said extension 16 is a closure-member 2 1 which may be swung down across theopening or hatchway 22 to close same against the entrance of dirt, dust or other objectionable foreign substances therethrough and into the valve stem inclosing space 19. A stop projection 25 determines the closed position of said closuremember 24, as may be seen from an inspection of Fig. 3 of the drawings.

The closing cap 18 is provided with a.-

transversevertical slot 26, through which extends a fulcrum pin 27 Pivoted upon said fulcrum pin is a lock-cam 28 provided with an outwardly extending leverarm or finger-piece 29 for manipulating the same.

When said lever-arm or finger-piece is turned downward the lock-cam 28 is swung inwardly and thereby engages the end of the reduced extension 21 of the valve-stem-S, exerting a downward pressure thereon so that the valve-member 6 with its washer 7 islocked firmly in-seated relation to the valve seat-portion 5. Since the downward movement of the lever-arm or fingerpiece 29 carries the free end of the same in contact with the body of the closing cap 18,.

the lock cam is stopped against further upward movement, when the same is once engaged with quently any tendency to upward movement of the valveimember 6 and its washer 7away from the-valve seat-portion 6 is securely blocked by vthe pressure of the lock-cam against the -extension of the valve-stein.

engaged the extension 21, and conse-;

When it is desired to operate the valve, the finger-piece or lever-arm 29 is raised or swung upward, this movement swinging the lock-cam 28 outwardly and away from the end of the extension 21 of the valve-stem 8,

' and clear of its path of movement in the guideway 21 of the closing cap 18, so that upward movement of the valve-stem, and consequently lifting movement of the valvemember 6 and its washer 7 is in no way interfered with, as is shown in Fig. 1 by the dotted line position of the lock-cam 28 and its finger-piece 29.

lever-member 30 having a hand-grip portion 1 31 connected therewith. Said lever-member 30 is provided, preferably with a 'fulcrum-notch 32 on its under side. Pivotally connected with said lever-member 30 is a downwardly and forwardly inclined latcharm 33, having at its upper end a perforate ear 34 which is disposed in a receiving-opening 35 provided in the body member therefor, a fulcrum pin 36 being passed transversely through the body of said lever-member and said perforate ear 34: to. 'pivotally connect said latcharm 33 in operative relation to said lever-member; Connected with said latch-arm 33, so as to extend outwardly therefrom in downward inclination beneath. the hand-grip portion 31 of said lever-member 30, is a trigger-arm 37. Connected with the under sideof said hand-grip portion 31 of said lever-member 30 is a leaf spring 38, the free end of which bears downwardly upon said trigger-arm 37 to swing the same downward, and thereby swing forward the lower end of said latchof said lever-- arm 33. The lower end of said latch-arm 33 is provided with 'a forwardly projecting latch-nose 39, which may 'be caused to engage one of a plurality of catch-nosings 40 surface of the faucet body 1.

In operation, the closure-member 24 is swung upwardly to uncover the'opening or hatch-way 22, and the free end of the leverrigidly projecting outwardly from the outer member 30-1s inserted therethrough until in the transverse slot or receiving open ng 20 of the valve-stem 8. In order to prevent thesaid transverse slot or receiving opening 20 from being displaced from properly alined relation .to said opening or hatchway 22 by the twisting or turning of the valve-stem 8, the latter is provided in its body-with a vertical slot 41 through which is passed a retainin pin 42, the latter bein supported in the ho y 1 of said faucet. As will be apparent said valve-stem may move vertically relative to said pin 42within limits determined by the length of the slot 41, but is prevented by the pin 42 from turning axially. The free end of said levermember being engaged in said receiving opening 20 of the valve stem '8, the levermember 30 is then lowered so that itsfulcrum notch 32 is engaged upon the fulcrum member 23 at the lower end of said opening or hatchway 22. The trigger-arm 37 is now swung upwardly toward the hand-grip portion 31, against the tension of the leaf-spring 38, thereby swinging backward said latcharm 33, and then a downward swinging movement is imparted to said hand-grip portion 31, which swings upward said free end of the lever member 30, and consequently lifts upward said valvestem 8, thereby raising said valve-member 6 and its washer 7 away from the valve seat-portion 5, against the tension of the spring 15. In order to hold the valve-member and its washer in partly opened relation to the valve seat-portion 5, the latch-nose 39 of the latcharm 33 is positioned opposite the uppermost catch-nosing 40, and then by releasing the v trigger-arm 37, the latch-arm is swung forwardly to engage said latch nose 39 with said uppermost catch-nosing 40, thereby holding or retaining said hand-grip portion 31 in its downwardly turned position, and said free end of said lever-member 30 in its valve-stem raising position. If it is desired to open the Valve-member to fully raised extent, to permitthe faucet to vent fluid to its full capacity, then the operations above described are carried out, except that I the latch-nose 39 of the latch-arm is engaged with the lowermost catch-nosing 40, which holds the lever-member 30 to a complete upswing position, with a consequent increasedamount of lift being imparted to the valvestem 8, whereby the Valve-member 6 and its washer 7 is completely raised to full extent away from the valve seat-portion 5.

Of course, it will be apparent that by disengaging the la'tch-arm 33 from either catchnosing 40, the swing of the'lever-member 30 'may be reversed, so that said valve-stem 8 ispermitted to move downward, and the valve-member 6 and its washer 7 is permitted to again engage the valve seat-portion 5 in closing relation thereto. The handle-member may then be removed, and the valve locked down by the lock-cam 28, and theopening or hatchway 22 closed by the closure-member 24, so that all parts of the faucet resume normal initial positions.

The nozzle-portion 4 is preferably exteriorly screw-threaded, as indicated at 43, for the reception of the internally threaded its periphery, with cars 45, having apertures 46 therein.
