Definitions

  • Sprinklers or sprayers should be capable of dispensing a liquid uniformly throughout or over the surface contemplated, but so far only swinging or oscillating devices are capable of accomplishing regular dispersion.
  • swinging devices of this character are attended by many inconveniences such as dangerous and multifarious projections and the like, a certain fragility due to the overhanding controls of lever arms and other external crank means, and also the necessity of a careful maintenance due to a permanent risk of clogging the mechanisms and ,a poor protection against mud splashes.
  • the major inconvenience is due to their limited field of application since, due to their inherent design, theyare suited only for sprinkling rectangular or circular surfaces. For example, if used to sprinkle a corner of a park limited by paths, the devices will also sprinkle the paths, which causes both a waste of the liquid and a nuisance to passers-by.
  • An objectof the invention is to provide a sprinkling or spraying devicewhich eliminates or reduces the variaxial cylinders mounted for relative rotational movement to one another; gear means for operatively connecting the turbine to relatively rotate said cylinders; and'aperture means in each of said cylinders for providing a variable opening through the pair of cylinders upon relative rotation of the cylinders, said variable pening(s) forming a passageway for liquid from the first chamber to a second chamber.
  • this improved device comprises a rigid, projection-free outer casing connected to the feed line, as a rule a flexible spray' hose.
  • the mechanism is enclosed completely in said casing and comprises a hydraulic turbine which, through the medium of reduction gears, is adapted to rotatably drive one or a plurality of movable cylinders rotatably mounted in one or a plurality of coaxial stationary cylinders each provided with suitable transverse openings.
  • the successive covering and uncovering of these openings by one another is thus adapted to produce a continuous'variation in the water output from each pair of cylinders so that the range of the liquid jets delivered-therethrough will vary constantly and regularly. Due to this sweeping acsprinkler comprising two pairs of coaxial cylinders,
  • the sprayed surface may vary considerably at will,
  • FIG. 1 is an elevational cross-section of the first embodiment of the sprinkler comprising two pairs of coaxial cylinders having-openings in the form of rectilinear slots, the rotation of these cylinders being produced by a single turbine;
  • I I v 7 FIG. 2 is across-section taken along line lI-II of FIG.1;
  • FIG..3 is a perspective view of a movable cylinder
  • FIG. 4 schematically shows another'embodimentof wherein the operative connection between the turbine and the movable cylinder is provided by means of a gear train; I 1
  • FIGS. 5 to 9 diagramatically illustrate the evolution in the course of timeand of the ranges of various liquid jets issuing from the same apparatus.
  • the device illustrated in FIGS. 1 and 2 comprises a dome-like cover 1 and a bottom 2 constituting a hollow outer body of the apparatus.
  • the sprinkler may also be buried so that its orifices 3 are flush with the ground surface.
  • the chamber 6 houses a liquid delivery mechanism including a turbine 9 rotatably mounted on a shaft '10 pivoted in bearings 11 and 12 rigid with the wall 8.
  • Shaft 10 "has an intermediate .portion 13 cut to constitute a worm meshing, as shown in FIG. 1, with a pair of identical and correspondinghelical gear wheels 14, 15 having parallel axis perpendicular to the turbine axis. It can be seen in FIG. 2 that the toothed portion of gear wheel 15 is out about a hollow chambers 6 cylinder 16 formed with an in tegral pivot or trunnion 17 journalled in a bearing 18-of wall 8.
  • this mechanism is independent of the shape of the sprinkler body; the entire mechanism is enclosed in an independent chamber (6) in the apparatus body and under these conditions the only requirement to be met is that the means providing this chamber must be adequately secured in the apparatus.
  • the toothed wheel On the side opposite to the trunnion or pivot 17, the toothed wheel is formed with a hollow cylindrical extension 19 open on one side; the resulting assembly may be considered to be a movable pinion-cylinder.
  • the aforesaid hollow cylindrical extension 19 revolves freely with its outer surface in a stationary open cylinder 20 rigid with wall 8.
  • Cylinders 19 and 20 each comprise a slot 21, as shown in detail on the movable pinion-cylinder of FIG. 3, this slot extending over I80 of the cylinder wall.
  • the left-hand pair of slots are shown exactly coinciding (maximum opening) and the right-hand pair of slots shown diametrically opposed (maximum closure); thus, chambers 6 and 7 communicate through the left-hand assembly with a negligible pressure loss.
  • the mechanism is driven continuously by the turbine 9, since water circulates continuously, but the total external output remains constant.
  • the slots 21 of the two cylinders 19 and 20 will successively and alternately cover and uncover each other thus causing a continuous variation in the cross sectional area of the opening available for the liquid flowing to the outside, from zero output to maximum output.
  • the total output remains constant because the cylinders revolve in opposite directions so that one of them is closed whilst the other is opened, the total area of the two openings thus forming an overall passageway of constant area at any time.
  • the turbine therefore revolves at a constant speed which ensures a regular operation of the apparatus.
  • FIG. 1 in which the left-hand pair of cylinders is shown in cross section taken along the line Il of FIG. 2.
  • the chamber is separated along the axis XX of FIG. 1 into two compartments by a partition integral with the cover 1.
  • Each of these compartments communicates with the open side ofa respective one of the two pairs of cylinders, and the orifices 3 are equally distributed on either side of said partition.
  • Such a partition is necessary, considering the constant total output of the cylinder outlets to provide the desired variation in the jet ranges, each compartment being variably supplied in the course of time, thus producing the desired variation in the jet ranges.
  • the cylinders are arranged such that the constant opposition is obtained between them in order to provide, for instance, a zero output on one side at the same time as a maximum output on the other side.
  • the alternating and pulsatoryjet produced uniformly sweeps the entire surface to be sprinkled and produces a particularly attractive aesthetic effect.
  • a suitable easily varied adjustment of the outputs, of the sprinkled area, and of the rate of operation of the assembly, are obtained at will simply by maneuvering the liquid supply valve or tap.
  • a turbine 22 supplied with liquid through an orifice 23 of a liquid supply hose is rigid with a worm 24 meshing with a gear wheel 25.
  • This wheel 25 is angularly solid with another worm 26 meshing in turn with a pair of respective pinions of movable cylinders 27 and 28.
  • the speed of turbine 22 is thus reduced through two successive worm gears and this is particularly advantageous when the liquid is supplied at a relatively high pressure.
  • FIGS. 10 to 21 diagrammatically illustrate examples of several orifice patterns, which may be circular, semi-circular, three-quarters or one quarter of a circle, rectangular, square, or parts of a rectangle or square.
  • using a three-quarter pattern permits the sprinkler to be used at the corner of a house; a half-rectangle permits use of the sprinkler along one side of a wall, and so on.
  • more than two sets of cylinders, or only one set, may be provided without departing from the basic principle of the invention and at the cost of only minor modifications, a substantially constant total output being preferably arranged so as to avoid any disturbance of the regular operation of the turbine.
  • a number of interchangeable covers may also be contemplated so that the pattern and shape of the sprinkled jets can be modified at will.
  • the output variation means according to. this invention have been described with reference to an arrangement comprising movable cylinders revolving in stationary cylinders, but the reverse arrangement, i.e. movable cylinders disposed externally of stationary cylinders, may also be used, or possibly even two cylinders rotating in opposite directions or in the same direction at different rates.
  • any suitable shapes may be given'tothe cylinder apertures, such as triangular slots, various holes, lozenge or diamond shaped apertures, and so on.
  • a triangular slot permits of accelerating the reduction or increase of the liquid outputs in a manner more than proportional to the rate of rotation of the mechanism.
  • the diameter of the various cylinders may be determined with a view to modifying the possible ratios of the openings as a function of the angle of rotation of the cylinders.
  • the devices constructed according to the invention are applicable to many uses, provided sufficient supply of pressure is employed.
  • use for the cooling of surfaces by spraying, the application of anti-freeze means, as fire-protection devices, for the decoration of parks, gardens and pools, for water displays, as well as for the dispensing of dissolved manure, the phytosanitary treatment of vegetables and plants, or the improvement of soils, as games, and so on may be contemb.
  • at least two pairs of coaxial cylinders mounted for relative rotational movement to one another and each associated with one second chamber;
  • gear means for operatively connecting the turbine to relatively rotate said cylinders
  • aperture means in each of said cylinders for providing a variable opening through each pair of cylinders upon relative rotation of the cylinders wherein the sum of said variable openings remains constant at any moment, said variable openings forming a passageway for liquid from the first chamber to each second chamber.
  • each pair of cylinders comprises a rotary inner cylinder and a stationary outer cylinder.
  • Device comprising a plurality of interchangeable parts individually detachably securable to said body, each of said parts comprising a plurality of said selectively distributed outlet orifices.
  • Device for sprinkling pressurized liquid comprising a bodyQmea'ns for dividing the body into a first chamber and at least one second'chamber, said first chamber having an inlet orifice for pressurized liquid, and said at least one second chamber having a plurality of interchangeable parts individually detachably securable to said body and each of said parts comprising a plurality of selectively distributed outlet orifices for spraying out liquid in selected directions, said first chamber housing:
