Description

Patented f7, 1930 GUADALUPE BUELNA, OF SANTA BARBARA, CALIFORNIA SPRINKLER Application filed June 12,

This invention relates to sprinklers and it has for its obj ect the provision of-a sprinkling device in Which jets or nozzles through Which the Water issues may be caused to rotate at nearly imperceptible speeds during the distribution of the Water over a relatively large area with high efficiency as the rotatable parts of the device are driven by the water during the sprinkling action thereof.

In sprinklersin Which the water issuing from the nozzles produces'rotation due to reaction, as ordinarily constructed and understood, .the speed or rate of rotation is relatively great and is dependent upon such factors as nozzle port area, angnlarity of (lischarge, inclination of the discharging jets or streams, frictional resistance to rotation due to downward pressure. or thrust upon the bearings of the rotatable parts, Water pressure and the like and thorough and elficient wetting of the sprinkled surfaces and even distribution of Water does' not always result from their use.v

It is therefore one of the principal objects -of the present invention to provide a spri'n kler in Which the speed of rotation of the arms or j'etting or spraying elements is such that an even and thorough wetting of the surfaces within the Wide area covered by the sprinkler and the breaking up of the issuing Water into very fine spray or a form approaching atomization is insured, and all Without limiting the radius sweeping the affected area, with respect to the Alength of such radius, and in which the length of such radius is even increased over the radii of prior forms of rotatable sprinklers of equal capacit 5A still ifurther object of the invention is to provide a rotatable sprinkling device of the impulse operated type in Which the sprinkler arms maybe caused to rotate at the proper rate of speed to cause the efficient distribution of the water regardless of the quantity of Water issuing therefrom or the pressure head of the same.

With the above and other objects in view, 1 the invention consists in the novel and useful gprovision, formation, combination and interrelation of parts, membersand features, all as 192s. seriai No. 284,817.

hereinafter described, shown inthe drawing,.and finally pointed out in claims.

In the'drawing: Y

Fig. 1 is an elevational View.

Fig. 2 is a sectional elevational view showing my invention and Fig. 3 is a sectional plan view taken on line 3-3 Fig; 2.

My invention consists ina generic sense of a chambered head provided With Water distributing nozzles, and mounted for relative rotation on a Water supplying source, and having means therein actuable by the Water entering said head for causing the rotation thereof.

In a more specific sense and referring particularly to the form of embodiment of the device shown in the drawing, the invention comprises a pipe 1 arranged preferably for connection at one end to a source 2 of Water supply. The other end of said pipe 1 is provided With a central bore 3, for purposes presently appearing and with a plurality of spaced circumferentially arranged vertical passageways 4 that are arranged to be normally closed by a valve 5, fitting over and operable on an upstanding tubular reduced extension 1 of said pipe and held seated upon the top of said pipe 1 by a spring 6, the tension of which may be regulated by a nut 7 on said tubular extension 1.

y'The pipe l is also provided with a plurality of lateral tangential ports 8, for cansing a plurality of jets of Water to be discharged therefrom, for purposes that will appear later. I Mounted for revolution upon said pipe 1 is a head 9 having a cylindrical portion 9 provided at the bottom thereof With an annular recess 9 for a packing 10. The cylindrical portion 9 is diametricall-y slightly greater than the pipe 1 to provide a space 11 through Which a portion of the Water may travel to exert a pressure upon the packing 10 and thereby insure'a water seal.

The cylindrical portion 9 of the head 9 is provided with a horizontal enlarged 'cylindrical chamber 12, and with a smaller cham' ber 13 surmounting said chamber 12, the smaller chamber having

water distributing nozzles

14 and 15 projecting therefrom. The head 9 is connected with the pipe 1 for rota- 1 tion relatively thereto, by any desirable means,

as for instance a bolt 16 arranged to extend freely through the central bore 3 of said f' pipe 1 and through the tubular extension 1 thereof and fastened, by threads or other- Wise, tol the top of the v.smaller chamber 13. The head 16 of said bolt 16 is arranged to bear against the inside end face of a central guide 1" provided at sthe end of the pipe l adjacent to the vertical circumferential passageways 4 therein.

The inner peripheral wall of the horizontal enlarged cylindrical chamber 12 vis provided with a plurality of substantially

eccentric surfaces

12 and 12 terminating in

shoulders

12 and 12. Within said chamber 12 is apellet or impulse member 17 in the nature preferably of a cylindrical body,

` which as shown in Fig; 3', is disposed immelocalities. j

water will issue from the ports 8 and cause-4 `/and'@permits the excess to be dissipated diately in the area or path of a plurality of the tangential jets issuing from the ports 8 in said pipe 1 and discharging within said 1 enlarged chamber 12. Under the influence of the jets issuing tangentially from the ports 8 and impinging tangentially` upon the pellet or impulse member 17, thepellet'is Caused to travel circumferentially and axially against the inner periphery of the enlarged chamber. lVhen during its revolutionary travel Within said enlarged chamber 12, the pellet is caused to engage one of the

eccentric surfaces

12 or 12 its speed of travel is increased until it strikes against the s houl'' ders of one ofthe

surfaces

12 and 12, as

shown in Fig. 3, at which time, owing to the increased resistance offered by the soulders- 12and 12 to the movement of .the pellet,"the head 9 will be caused to be revolved by it until it escapes from one or the other` of the shoulders under the force of the tanf gential' jets.

Since the travel of said pellet within said chamber 12 is continuous underv 'the pressureI or influence of said jets, it will be apparent that the head 9 is thereby caused to revolve continuously intermittently as theeimpulse member alternately strikes first one shoulder andl then the other.

The device is adapted vfor allwater .pres

sures, which vary consider in difierev At normal or pressures tl'lfe the pellet to travel within the enlarged chamber12-.' Where,'however,- greater or higher pressures are encountered, the excess pres-r v ,sures of water above that required for a slow rotating operation ofthe head 9, willbe ref lieve'f lffiy-fhenv such pressure unseats the' valve througlegtliie .passageways 4 in the pipe 1 into the 13 andpeven'tually through the nozzles 14 and 15and by which nozzles itis area to sprinkled togetherwith the water which reaches the nozzles through the ports 8.

What I claim, is:

1. A sprinkler comprisin a head mounted.

for rotation and arranged ol' connection to a source of water supply, water distributing nozzles projecting from Nsaid head, an unattachedV member within andv arranged for periodical impact with said head, and means for jetting the water into said head to cause said member to travel relatively. thereto l and periodically therewith.

2. A sprinkler comprising a head mounted for rotation andja'rranged for connectlon to a source ofwater supply, said head having la water outlet, and provided in the peripheral wall thereof with a shoulder, and an unattached Water impelled member within and arranged to travel relatively to said head to engage said shoulder intermittently and thereby slowly rotate said head.

3. In a sprinkler, a supply pipe, a head rotatable thereon having a .water outlet, means for etting the water withinsaid head, a member freely disposed within said head and arran ed for circular travel therein under the in uence of said water jets, and neans on the peripheralwall of said head and disf posed in the path of travel of said member to cause said head to be rotated intermittently by the periodical impact of said member with said means.

4. In a sprinkler, a supply pipe having.

rotatable thereon having a water outlet, a A

member axially rotatable and 'revoluble' within and independently of said head by the jets of water issuing from s aid ports, means on the wall of said head for periodically rie-y ceiving the impact of said member thereby ,to cause an intermittent rotation of said h nd means. fo` 'controlling the discharge of member.
