HOSE-NOZZLE.

Specification of Letters Patent.

Patented May 18, 1915.

Application filed May 4., 1914. Serial No. 836,221.

To all whom it may concern Be it known that we, SAMUEL K. ELLIOTT, a citizen of the United States, residing at San Diego, in the county of San Diego, State of California, and LINNAnUs C. POND, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Hose- Nozzles; and we do 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.

This invention relates to improvements in hose nozzles.

The object of the invention is to provide a nozzle having simple and ,eflicient means for controlling the configuration of a stream of water flowing through the sprinkler thereof and to provide means whereby a stream may be directed from the nozzle in a fine spray or a tubular stream especially applicable for long distance sprinkling.

Another object of the invention is to provide a simple and inexpensive device that may be operated instantly to change the character of the stream without diminishing the volume of water directed from the nozzle and also means whereby the pressure in the hose is immediately relieved after the water is turned off at the hydrant.

With these and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings :Figure 1 represents a side elevation of this improved nozzle; Fig. 9. is a side elevation of the inner tube with the outer tube or casing shown in section; Fig. 3 is a longitudinal S6Jl011 taken on the line 33 of Fig. 2; Fig. 4- is an end elevation of the nozzle; Fig. 5 is a transverse section taken on the line 55 of Fig. 2; Fig. 6 is a detail perspective view of the spreader; Fig. 7 is a longitudinal section thereof; Fig. 8 is a longitudinal section showing a slightly modified form of the invention; Fig. 9 is an end elevation thereof; Fig. 10 is a transverse section taken on the line 1010 of Fig. 8; Fig. 11 is a detail perspective view of the modified form of the spreader shown in Fig. 8; and Fig. 1.2 is a longitudinal section thereof.

In the embodiment illustrated in Figs. 1 to 7 an outer tubular casing 1 is shown having a thickened mouth or discharge end 2 and longitudinally spaced annular ribs 3 and at on its outer face near its inner end for a purpose to be described. The inner end of this casing 1 is provided with an annular shoulder 5 on its inner face which is adapted to engage a cooperating shoulder on an inner tube to be described to form a limiting stop for said outer casing.

Slidably mounted in the tube 1 is an inner tube 6 in the outer end of which is secured a collar or sleeve 7 which is welded or otherwise secured to the inner face of said inner casing and the rear edge thereof is adapted to form a shoulder or abutment for a coiled spring to be described. Soldered or otherwise secured to the inner end of the tube 6 is a hose coupling 8 for attaching the nozzle to the hose. This inner tube 6 has an annular shoulder 9 formed on its outer face at a point spaced from its inner end a predetermined distance and which is adapted to be engaged by the internal shoulder 5 of the inner end of the outer casing for limiting the extension of said outer casing relatively to the inner casing and to prevent accidental disengagement of said casings.

The inner tube or casing 6 is provided with a longitudinal depression forming a socket 10 in its outer face in which is mounted an outwardly bowed leaf-spring 11 adapted to frictionally engage the inner face of the outer tube 1 to hold said tube in adjusted position on said inner tube and prevent the force of the water from changing the position of said tubes accidentally.

The outer end of the collar 7 is preferably beveled or inclined downwardly and inwardly to form a seat to receive the spreading element 12 which is here shown in the form of a truncated cone having a socket 13 at its smaller end in which is mounted a ball or head 14; of a stem 15 whereby a ball and socket connection is provided between said sprinkler head or spreader 12 and said stem 1 15 whereby said spreader is permitted to adjust itself relatively to its seat and thus produce the most perfect results. This spreader has a slot 16 extending longitudinally therethrough which is designed for relieving the pressure of the water in the hose between the hydrant and the spreader after the water has been turned ofi". The rear end of the stem 15 is enlarged to form a stop or shoulder 15' adjacent said end, which shoulder. is designed to form a stopor abutment for one end of av coiled spring 17. which encircles said stem and bears at its other end against the inner edge of the collar 7. A spiral spring is here shown with its smaller-end engagingthe abutment formedby the shoulder of the enlargement and its larger end engaging the inner edge of the collar 7.

It will be obvious from the abovedescription that the water under pressure passing through the nozzle will force, the spreader 12 outwardly against the, tension of the springlfZ thereby compressing said v spring between the stop 15; and the collar 7 thus opening the nozzle and permitting water to pass out between said spreader. and the seat formed on the collar'Z, willbe noted that all water discharged. fromthe nozzle, must necessarily. flow first throughthe spaces between thevarious convolutions of the cone.- shaped spring 17 and that these convolution'sare'moved toward each other. as the spreader is forced outwardly by the pressure of the water. This is extremely advantageous, since. should thefwater pressure, be so great as to force the. spreader too. far. from itsseat, thereby allowing a stream of undesirablepressure to,be furnished, thefamount of water flowing through the spring. is automatically diminished, since. the, spaces. between the. convolutions of said spring" are decreased in size, as the spring. is com? pressed. On the. other hand, when; the pres- Sure is normal, the spreader will be so. p0.- sitioned as to allow, the. spring to serve; to permit the proper amount of water. to flow through the device. As soon asthe water is cut ofi, this spring 17 will again expand thereby retracting, the spreader 1 2 and seating on the collar 'Zclosing the nozzle. This backward movement of the, spreader 12 under the action of the spring 17 will slightly compressthe water in the hose be tween the hydrant where it has been out off and the sprinkler and this pressure may be relieved by means of the, slot '16 which extends longitudinally through the spreader and permits the water to pass out therethrough and; drain the hose.

The inner and outer tubes 1 and 6 are here shown substantially o f'the same length but they may be of different lengths if desired and, the. outer tube, is slidable on the inner tube for the purpose of varying. and controlling the configuration of the stream of water issuing from the nozzle. For instance, when the outer tube 1 isproiected to its full extent as shownin Eig. 2, the spreader head will-'be positioned some distancewithin said tube so that when the Water is: to the hose. and forces said spreader-open, the walls of the outer tube which extend beyond said spreader head will confine the stream ofwater and direct it in a tubular stream from the hose. The force and size of the stream may be varied by lengthening or shortening the distance between the outer endor mouth of the tube 1 and the spreader 12 of the other end of the inner tube 6. When the outer ends of the inner and outer tubes are disposed flush with each other, the force of the water passing out will open the spreader and the water will be discharged inthe form of a fine spray spreading out in all directions. V I

The annular ribs 3 'and 4 which are preferably roughened. or knurled are designed to receive; the thumb of the operator between them. so that the outer sleeve may be moved backwardly or forwardly with one hand for varying the, size of the stream ejected.

From the above description it will be obviousthat the character of the stream may be, quickly changed with one hand without diminishing the volume of water directed from the nozzle.

In the form shown in Figs. 8 to 12 the inner and outer tubes 1 and 6 are similarly constructed to those shown in the other figures thedifi'erence residing in the formationof the spreader or' head 12 and in the means carried by the stem 15 between which and the ring 7 f the coiled spring 17 is mounted. This spreader 12 the outer end of whichis reamed out to form a cup-like head,

has two; smallholes 16' drilled at an angle through said spreader and; which are designed for the same purpose as the slot 16 in the spreader 12, that is torelieve the pressure in the hose after the water has been wt. f th y r A spider 19 is fixed to the inner end of the stem 15 and is slidable within the inner tube 6 forminga guide for said stem and the spreader connected therewith.

The operation in this form of nozzle is exactly the same as that above described nd consequently, no further description is thought to be necessary. 7 r

What we claim as new is .annularseat in its outer end, a spreader en- 7 gaged with said seat and adapted to move dll lwerdly therefrom, a stem extending inwardly from the spreader into the tube,'a stop on the inner end of said stem, and a conical spring whose contracted end encircles said stem and bears against the same and against said stop, its expanded end bearing against the inner end'of the annular seat, whereby water forced through the tube must pass between" the convolutions of the spring, and whereby said convolutions will be forced "toward each other when the spreader is moved excessively outwardthereby decreasing the amount of water discharged from the nozzle. 1

2. A hose nozzle comprising a tube having a spreader seat at its outer end, a spreader engaged with said seat and adapted to move outwardly therefrom, and a conical coiled spring disposed within the tube and through the convolutions of which water discharged therefrom must pass, said spring exercising its tension to retain the spreader in engagement with its seat, whereby excessive outward movement of the spreader will compress the spring and check the discharge of water therethrough.
