SPRAYINGFjrJO'ZZL/E..V

Be it known 'thatt I, JOHN J. McGowEN, "a

l resident of Forest Home, in the county ofl Tompkins and State of v New York, have in-l vented certain new and usefullmprovements in Spraying-Nozzles; and I do hereby declare -the lfollowing to be a full,clear, andexact de- 'scription of the invention,such as will venable others skilled in the art Vto which it pertai'ns to make and use the same. .l Y 'The invention relatesvto spraying nozzles for pipes, and 'has for its object. to kconstruct Asuch adevice'so that it can be readily changed dotted lines.

from a spraying to along distance nozzleand will be adaptedfnnder either adjustment to clear itself of'accidental obstructions, and it consists in the, construction hereinafter' del scribed and particularly pointed out.

In the accompanying drawings Figure l is a longitudinal section of the nozzle, the clear- "ing position-of the partsbeing indicated in Fig. 2is an end elevation partlyl in section. Fig. 3Y is a side elevation. of the device adjustedV for spraying, partly inv section, and Fig. Liris a. section on line 475-4 of Numeral 1 denotes a nozzle tube having a screw threaded socket2 adapted'to fit the corl respondingly threaded end of a water pipe or l 30. 4

hose coupling.

.Bindicates a short transverse tube commu` nicating with tube 1 andhavingits end stopped with a plug 4 having preferably its inner face 4' inclined to adapt-itto change the direction.. tubes` to-y .o

. the straight slot 9 or in thespiral slot 10 as required by the uses to be hereinafter .described. In the end of. the piston 6 is a slot 6 to receive the transverse bar or head'V 1l of a. spring 12. The opposite end of the spring 12 is heldbetween two lugs 13 fast on tube l.

-14 is a sleeve sliding freely. on said tube and having a yoke y15 adapted to receive 'the spring the construction being such that the 'A moving of thejsleei-'e toward the tube 3 ini- 4 creases the tension' ofthe spring.

' 'Upon vthe endof the piston sleeve 7are projections 7 against which-the crossy bar 11 of the spring bears whenr both piston and sleeve bear upon the inner end'ofthe plug4 and the knob 8 is in slot 9. holdslboth sleeve and pistonagainst the plug.' The piston partially closes the portonpassage made in theplug under the inclined wall 4 .which port at its lower part is widerthan the diameter of the piston and is always partially juste'd as just stated this sleev'ecl'oses the passage to the outletoijfi l`1 ce`,'-ullessfthepressure in tube'l .is (sufficient to ovei'co'ine the; spring and move the piston; and sleeve 'away from the plug to give aescape to the fluidthrough orifice 5, as will be the'case inaetual opera- 'tion for throwing' thewater :long distances. In casevof an obstruction at or lnearthe junchaving been previously suitably adjusted, the 'pressure'. will be sufficient `to lrnovethe piston and sleevelto the .positions'indicated i'n dotted lines in Fig'. 1 and give anex'it'to the obstruction, the parts being returned-bythe spring to their normal operating positions'.- In such clearing operation the knob `S moves in the slot '9.v f 1 To adjust the device for nearat hand spraying theknobisfmoved into the inclined slot 10 and thesleeve thereby turned,.with the :.eect to disengage the projections 7 on said saidsleve away from plugfi as 'indicated in ,FigB. Byjthis adjustment, circumferential outlets 16l are opened one on each side of the piston Gthrougli which opposing'fcurrents may issue with the eect to break each other in to ne spray, to which'direction is given in part Under this adjustment ythe outlet will be automatically enlarged to give escapeto an obspring yielding to allow the piston to move outv of the path of such obstruction. The size of the opening can be adjusted by turning the sleeve by the medium of the knob.

It should be understood that the outlets or openings above referred to are circumferenopen unless closed by the'sleefve'?.

,95. `struction as in the case first described, the

tial spaces at the sides of piston G and at the endiofsleeve 7 and between rthe end of said sleeve and the plug 4:. These outlets are closed bythe sleeve abuttingr against the plug as indicated in Fig. l and they are opened by withdrawing the sleeve, as shown in Fig. 3 by `at the inner end of the sleeve. never entirely closes the passage or port unmeans of knob 8 and slot 10 in which latter case there is free communication from the interior pipe l along the inclined wall 4 of the plug and out on each side around the piston through said circumferential openings IG The piston der` the inclined Wall i'. Frein the above description it will be understood that the piston is in substance a. valve always partially open and adapted to be automatically opened `,vider by pressure in the pipe to permit the discharge of an obstruction and thatthe sleeve is in effect a valve controlled at the will of the operatorto entirely close or open the outlet..

I anilaware that spraying nozzle valves have been provided with handles whereby they might be opened wide to discharge obstructions and that in other cases the spray openings are normally closed except when opened j by` pressure in the water pipe and such matters are not of my invention.

Il am` aware that a spraying device has been provided with aspring-held valve of frustol conical form having a longitudinal groove in vention.

i its exterior and arranged and adjusted to be `openedby a lever to permit the escape of obstructions, the supply pipe being' provided with a cock, and such device is not of my in- It is characteristi of my improvement that the device is automatically opened 'uy interior pressure being constructed and arranged for that purpose. Y And to this end areprovided one or more orifices or ports such as 5 'communicating directly with the pipe incom mnnicating directly with the pipe, a valve movable transversely of the pipe and outlet and adapted 'to partially close said outlet and adjusted tobe'automatically opened by interior pressure, a spring to hold the valve partially closed except when its tension is overpiston valve 0, the sleeve come by pressure within the supply pipe, and a distinct eut off valve to entirely close said outlet at will all combined substantially as set forth. t

2. In a spraying nozzle the combination of the tube 3 stopped at one end by plug 4, the piston valve (3, the sleeve 7 surrounding the piston and adjustable independently thereof,v

and the spring adapted to yield to permitthe piston valve to move out of the path 4of the current or of an obstruction, substantiallyas Set forth. iff-f 3. In a spraying nozzle the combination of the tube 3 stopped at one end by plug 4, the 7 surrounding said piston and adjustable independently thereof, and the spring, said sleeve k Y one position to be held together with thepiston in Vyielding manner by the spring 'and under such adjustment to be moved lengthwise by pressure in the pipe and also adapted to be relieved from the spring and held against such pressure, substantially as setpferth.

4. In a spraying nozzle the cross tube, the piston 6 having slot 6',the sleeve 7 having projections 7 and the sp'rng secured on tube l and provided with a head to engage the slot, substantially as eet forth.

In a spraying nozzle the tube 1 havixg cross tube 3, the piston b' having Slot (itthe sleeve 7 having projections 7 and the spring secured on tube *l5 between the lugs and provided with a head to engage theslot,andthe tension adjusting sleeve, substantially as set forth. t f

6. In a spraying nozzle the tube 1 having cross tube 3 provided with an exit orifice and slots 9 and 10, the pistou, the sleeve having the knob adapted to move in either of said slots and the springto holdthe piston in closed position, substantially as set forth;

7. I n a spraying nozzle the Lube 1 provided with cross tube 3 the latter being. provided with an outlet orifice and stopped atene end with a plug having the inclined face 4 'and shoulder 4, the piston and piston sleeve and a spring tending to hold said piston and' sleeve against the shoulder under the orifice, Spbstantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribiing witnesses. v t
