NOZZLE.

To all whom it may concern:

Be it lrnown that I, J AMES H. HULrNGs, a citizen of the United States, residing at Parsons, in the county of Tucker and State of lVest Virginia, have invented new and useful Improvements in Nozzles, of which the following is a specification.

This invention relates to nozzles, the object of the invention being to provide a simple, inexpensive and convenient type of nozzle whereby a fine or coarse spray or solid stream may be ejected atwill, and which may be used upon an ordinary garden hose for watering or employed for discharging heavier substances, such as paint, whitewash, etc., without liability of clogging.

The invention consists of the features of construction, combination and arrangement of parts hereinafter fully described an-,d claimed, reference being had to the accompanying drawing, in which Figure lis a top plan view of one form of nozzle embodying my invention. Fig. 2 is a side elevation thereof. Fig. 8 is a longitudinal section of the same. Fig. 4 is a cross section on the line 4-4 of Fig. 2. Figs. 5 and 6 are longitudinal sections, showing modified forms of nozzles with the cap in different positions. Fig. 7 is a longitudinal section through the head of the nozzle, shown in Fig. 6.

Referring to Figs. 1, 2, 3 and 4 of the drawings, 1 designates the tapering body of the nozzle, having at its enlarged end the ordinary internally screw threaded iange 2 for coupling connection with a hose or the coupling element of any other source of supply of the liquid to be discharged.

At its outer end the nozzle is provided with a circular head 3 e'ccentrically arranged thereon an'd through which the bore 4 of the nozzle extends eccentric to the axis of' said circular head. The outer.surface of the head is formed with a thread 5 to receive an internally threaded cap 6, which cap is adapted to serve the function of a valve and is provided in its end wall with an eccentric discharge opening 7 to register with the bore 4.

Formed upon the outer end of the nozzle and connecting with the inner surface of the laterally projecting portion of the eccentric head is a boss 8 having a longitudinal chamber 9 slidably receiving a detent or locking device 10 formed with a V-shaped or reversely beveled forward end 11 to en- Speccation of Letters Patent.

gage correspondingly shaped ratchet teeth l2v on the cap, whereby the latter may be locked in a variety of positions. The detent is of greater length than the chamber of the housing 9 and its forward portion is arranged to move over a plane surface 13 formed on the head by cutting away a portion of the screw thread, thus allowing the detent to follow -the cap a determined distance as the cap is screwed outward to lock the same at a variety of points.

On the forward portion of the detent is a shoulder 14 engaged by a coiledv spring 15 disposed in the housing 9 between said shoulder and an apertured retaining plug or washer 16 at the inner end of the housing, through which the detent is free to slide, said spring thus being arranged to force the detent forward into locking engagement with the cap.

Then the cap is fully screwed on the circular head, its outer end wall closely engages the outer end of the head and its opening is out of registry with the bore to cut off the discharge of liquid. In such position of the cap, the detent is pressed backward against the resistance of the spring. When the cap is turned outward to different degrecs away from the end of the head and with its opening at various points with relation to the bore of the nozzle, a fine or coarse spray or a solid stream will be discharged at will, theposition of the discharge opening in the cap relative to the end of the bore regulating the amount and character of the stream discharged, as will be readily understood.

The cap has a rotary and endwise movement in which it is locked by the action of the detent to an extent approximately half of its degree of travel on the head, thus enabling the liquid to be discharged in a va riety of ways while the cap is locked positively in position against casual movement in either direction. The forward movement of the stem is limited by its engagement with the rear end of the head and the continuous thread at the forward extremity of the plane portion, so that when the cap is rotated in a retrograde direction beyond the latter named point it may be quickly and conveniently turned o without resistance.

It will thus be seen that a discharge cap or valve is provided which has both a rotary and an endwise movement on the eccentric head, allowing it to be adjusted to a greater degree for regulating the character of the stream to a greater extent than if it simply rotated in a i'ixed plane on the nozzle. It will also be seen that it will be locked positively in all of its operative positions, and` that, asl there are no surfaces to become substances may be discharged with facility, increasing the range of usefulness of the nozzle.

'In the form of my invention shown in Fig. 5, the sliding spring actuated detent and ratchet teeth on the cap are dispensed with and, in lieu thereof, the nozzle is provided with a lug 1,7 formed with a threaded opening for the passage of a binding screw 18 which may be moved forwardly to bring its free end to bind upon the inner` end of the adjusted nozzle to hold the same in adjusted position.

In the form of the invention shown in Figs. 6 and Z a Hange or collar 19 is provided at the inner end of theeccentric head and a threaded washer or nut 20 having a milled periphery is provided for adjustment on the threads of the head to bind against the end of the cap to lock the same in position.,

Having thus described the invention, what is claimed, is

1 A nozzle formed at its outer end with an integral eccentric head externally screwthreaded and through which the bore of the nozzle eecentrieally extends, a one -piece threaded cap having a discharge opening in its outer end wall, said cap having a rotary and longitudinal movement on the threads of the head, and a locking device on the head movable to engage the cap to lock it in a Variety of positions.

2. A nozzle formed at its outer end with an integral eccentric head externally screwthreaded and through which the bore of the nozzle eccentrically extends, a one-piece threaded cap having a discharge opening in its outer end Wall for coperation with said bore, said cap having a combined rotary and longitudinal movement on the threads of the head, and a locking device on the nozzle adjustable to. engage the inner rim edge of the l clogged, paint, whitewash and other thick cap to lock it in a variety of positions.

3. A nozzle formed at its outer end with an integral eccentric head externally screwthreaded and through which the bore of the nozzle. eccentrically extends, a Yone piece threaded cap having a discharge opening in its outer end wall for cooperation with said bore, said cap having a combined rotary and longitudinal movement on the threads ofthe head and being provided at its inner rim edge with ratchetteeth, and a spring actuated sliding detent on the nozzle longitudinally movable thereon to engage said ratchet teeth and lock the cap in a variety of adjusted positions.

t, A nozzle provided at its outer end with an eccentric head integral therewith and through which the bore of the nozzle eccentrically extends, said hea-d being externally screw-threaded, a one-piece threaded cap having a discharge opening in its outer end wall for coperation with said bore, said cap having a combined rotary and longitudinal movement on the threads of t e head, a casing upon the nozzle in rear of the eccentric head, a stem slidable longitudinally in Said casing and carrying a detentto engage the rim edge of said cap, and a spring within the casing and acting on the stem to normally hold the detent in engaging position.

In testimony whereof I aix my signature in presence of two witnesses.
