APPLICATION FILED APRl 25, I92I- Patented-Sept. 5

rares FRANK E. CBO'LTO, OF DALLAS, TEXAS.
WELL-WASHING DEVICE.
Application filed .April 25,y 1921. Serial No. 464,285.
To @ZZ wiiom t may concern: n l
Be it known that l, FRANK E. CROTTO, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in lVell-VVashing Devices, oi which the following is a specification.
This invention relates to new and useful improvements in well washing devices.
The object oi3 the invention is to provide a washing device tor artesian wells without screens and in which an enlarged pocliet is formed at the bottom of the well. A particular featurel of the invention is theprovision of outwardly swinging nozzles arranged to be swung outwardly by the pressure of the washing fluid and automatically retracted when the pressure is cut oft. Another object is to provide a plurality of nozzles` wheieby the washing is carried out more expeditiously and more evenly performed.
A particular feature ot the invention is to individually mount the nozzle, wherebythe obstruction to one or more will not prevent the outward displacement of the other. Another result sought is to make'the device in a compact and simple manner and in this respect is an improvement on my application filed January 31, 1921, Serial No. 441,257.
A construction designed to carry out the invention will be hereinafter described to gether with other features of the invention.
The invention will be more readily understood from a reading of the following speciiication and by reference to the accompanying drawings, in which an example of the invention is shown and wherein:
Fig. 1 is an elevation of a device constructed in accordance with my invention,
the nozzles being extended in the well,
Fig, 2 is a .vertical sectional view, indicating` the extended position otl the nozzles in dotted line,
Fig. 3 is a cross sectional lview on the line 3-3 of. Fig. 2,
Fig. 4 is a cross sectional view on the line 4 4 ot Fig. 2, and
Fig. 5 is a cross sectional detail on the line 5 5 of Fig. 2.
In the drawings the numeral 10 designates a cylindrical housing having a Solid core 12 in its lower portion and terminating flush with its lower end which receives a guide plug 11. Immediately above the core the housing is provided with an inwardly y sockets.
extending annular bead 13 on which a socket plate 14 is supported. The plate 14 has a plurality of equally spaced sockets 15 suitablyr shaped to receive the ball heads 16 of nozzles 17 depending from said plate. The
nozzles have their lower ends curved outi l wardly and beveled, whereby the bore of the yEach head 16 has a pair ot ears 2O between which the lower end of an angular plunger 21 is pivoted. The plunger extends up through iingers 22 extending from the lower edge of an inverted valve cap 23.y The plungers are angular in cross section so as to slide vertically between the lingers and ywhereby rotation is obviated. Each plunger vhas its portion normally extending above `the fingers, vsubstantially perpendicular and belowsaid fingers is inclined inwardly to itsr point of engagement with the ears 20.`
Coiled springs 24 are confined on the lower portions of the plungers between the fingers and collars 25; while other coiled springs 26 are confined on the uppervportions of the plnngeis between the lingers and collars 27. The coiled springs 26 have a greater tension than the coiled springs 24 whereby ythe plungers are held elevated and the nozzles 17 are retained in their sockets.
An enlarged collar 28 has its lower end reduced and screw threadedinto the upper end of the housing 10 whereby a liush eX- terior joint is had. The upper end of the collar is contracted into a nipple 29 and receives the lower end of a string of pipe 30. A. bushing 31 is screwed into the nipple from the interior ot the collar and telescoped into the cap 23. The cap 23 is provided with a transverse. pin 32 passing through slots 33 in the lower end ot said bushing. kA. coiled spring 34 has its lower end fastened on the pin 32 and its upper end supported on a transverse pin 35 mountedA in lthe' upper end of the bushing. The bushing is provided with a plurality of ports 36 which are normally covered by the cap 23. The cap 23 in connection with the bushing constitutes a valve which is normally closed.
In operation the device is lowered into the well until the housing 10 is within the oil sand pocket or other cavity. Vlhe cleaning,` fluid, which is preferably water and which may be heated if desired, is pumped into the pipe 30 and enters the bushin 31. ylhe cleaning fluid exerts a. downward pressure on the cap against the tension ot' the spring Sil, whereby said cap is displaced downwardly. The ports 3G are located so that the eap may more downwardly a short distance before said ports are uncovered. lllhen the cap is mored lownwardly the springs 2d and 26 will not be coinpressed to any extent and the plunger-s will thus swing the head 16,whereby the nozzles li' will be swung outwardly from their soeliets into the well.
It one otthe nozzles should encounter an obstruction the spring Bt oit this plunger will yield, thus permitting the cap to continue its downward movement and not int/ei :tering` with the outward displacement ot the other nozzles. This is a yery important tea ture because il the obstruction to one ot the nozzles prevented the out-ward disp] a1.; ement oit tl e other, the resultobtained would not` be as satisfactory. litter the Cap 23 has been displaced downwardly sui'iiciently to uncover the ports 36, the nozzles will have been swung to their outward limit and the clean ing tluid will pass into the collar 28 and down through the housingl 10 to the nozzles. The cleaning lluid will thus be discharged in jets :from the nozzles against the sides ot the well proper, whereby the latter yill be cleansed. By rotating the pipe 30, 'the entire side walls of the pockets will be treated.
then the pressure of the cleaningv tluid is out oil the spring 34 will immediately pull the cap upwardly until the pin reaches the top ot the slots rl`he springs 26 resting,- on the lingers QQ will carry the plungers upwardly, whereby the nozzles will be swung` into the pockets 18'. The device will otl'er an unobstructed contour and may be withdrawn from the well. lllhile lhare shown Vtour nozzles, it is to be understood that the number may be varied.
Various changes in the size and construe tion of the parts as well as modifications. may he made without departing` from the spirit oit the invention.
lllhat l claim, is:
l. In a well cleaning device, a housing having a plurality ot openings, a nozzle mounted within each opening,T ot the housing` and arranged to be swung outwardly from the opening of the housing, and means for simultaneously swinging said nozzles trom the housing, each nozzle being' arranged to yield inwardly independently of the other nozzles and the swinging means.
Q. ln a well cleaning device, a housing having a. plurality of openings, a nozzle mounted in each opening and adapted to swing,- outwardly therefrom, tluid pressure operated means for swinging the nozzles, and resilient means 'for independently sus taining each nozzle, whereby each nozzle may he depressed inwardly independently of the other nozzle.
3. 1n a well cleaning device, a housingv having a plurality or openings, piyoted nozzles mounted in the openings, a tubular fluid supply member, a valve normally obstructing the passage ot fluid to the nozzles, connections between the valve and the nozzles, said yalve operatingi said Connections to swing the nozzles outwardly, and resilient elements mounted on said connec tions, whereby each nozzle may be indeA pendently swung,v inwardly after haring,- been swung' outwardly.
4. In a well cleaningv deyice, ahousingl having a plurality ot openings, a plurality of nozzles mounted in the openings and pil# oted in the housing, a tubular tluid supply member projecting into the housing, a 'alte slidably mountedA on the member andnormally obstructing; the passage oit tluid to the` housing there trom, means tor sustaining' the Valve in its normal position, plungers connected with the nozzlesand the yalre, sustaining springs mounted on the plungers,l and compression springs als mounted on the plungers, the valve having engagement with the plungers relatiyely between the sustaining and compression springs.
5. In a well washing derice, an elongated housing` having` a plurality oit openings in its lower portion, a transverse support .hai7d ing,` sockets above the openings ot the housing, nozzles haring,` ball heads mounted in the sockets ot' said support, a tubular inember in the upper end oi the housing, a sliding cap mounted on the member` a coiled spring;` supporting` said cap, projections entendini?,` from the cap, ylungers passing' through said projections and having their lower ends con nected to the heads oit the nozzles, coiled springs confined on the plungers between the projections and the nozzles, and sustaining oiled springs mounted on the plungers between the projections and the upper ends thereof.
