7 Claims.
This invention relates to a rotating sprinkler.
An object of this invention is to provide a sprinkler which is capable of comparatively slow intermittent rotary motion, for instance one revolution in an hour, for the irrigation of orchards or other cultures, Where it is desirable to apply the water on any portion of the surface only at intervals for better penetration into the soil, thereby lessening pudd'ling or the trappin of air in the soil, and thereby avoiding the constant wetting of the lower branches of trees, and thus preventing the spread of fungus or other diseases or the splitting of fruit.
Particularly an object of this invention is to provide a sprinkler in which the rotation of the sprinkler is accomplished intermittently by a rocking mechanism operated by the alternate filling and emptying of a container on said rocking mechanism automatically.
I am aware that some changes may be made in the general arrangements and combinations of the several devices and parts, as well as in the details of the construction thereof without departin from the scope of the present invention as set forth in the following specification, and as defined in the following claims; hence I do not limit my invention to the exact arrangements and combinations of the said device and parts as described in the said specification, nor do I confine myself to the exact details of the construction of the said parts as illustrated in the accompanying drawings.
With the foregoing and other objects in View, which will be made manifest in the following detailed description, reference is had to the accompanying drawings of the illustrative embodiment of the invention, wherein:
Fig. l is a sectional view of a rotating sprinkler constructed in accordance with my invention.
Fig. 2 is a top plane view of said rotating sprinkler.
Fig; 3 is a sectional detail view of the ratchet mechanism through which the rocking motion is converted into rotation of the sprinkler, and
Fig. 4 is a fragmental detail view of the transmission from the ratchet operated shaft to the nozzle structure.
In its general organization my invention, in its illustrative embodiment, includes a rotatable nozzle unit 1 supported on a relatively stationary conduit unit 2, a rocking or oscillating unit 3 which is oscillating on a horizontal axis and is actuated by the action of gravity on a varying volume of water issuing from the nozzle, and a transmission mechanism 4 to convert the oscillatiii) 2 ing or rockin motion of the unit 3 into rotary motion of the nozzle unit 1.
The stationary unit 2 includes a pipe 6 on the top of which is a threaded collar 1 to which is connected a coupling 8-.
Inside of the coupling 8 are a pair of spaced bearing bushings I4 in which latter is rotatably held a nozzle tube l6, which is the supporting member of the nozzle unit I. The lower end of the nozzle tube 16 has an outwardly enlarged head ll. On the tube [6 and against this head is a fiber washer [8 which bears against a seat formed by the lower bushing l l, so that under water pressure the Washer 18 seals the space around the tube 16. The outer end H! of the tube It is externally threaded and is provided with a collar 21 fixed on the threaded portion of the tube It. A pair of diverging arms 22 extend from the collar 2! toward and above the transmission mechanism 8-. The outer end of each arm 22 terminates in an outwardly extending abutment tip 23.
A nozzle tip 26 is provided on the outer end of the threaded end l9v of the tube Hi. The nozzle tip 26 has a side orifice 21 which discharges a stream of water upwardly and laterally with respect to the axis of the tube l6. The outlet orifice 21 faces in the direction generally opposite to the space between the diverging arms 22 of the collar 2|.
Near the upper end of the externally threaded coupling 8 are spaced bearing bushings 9 and II the heads or top flanges of which form seats for a horizontal plate [2' the central hole l3 of which is journalled on the body of the upper bushing I I. Said plate i2 is rotatably supported between the top flanges of the bushings 9 and II. A pair of spaced pins 24 extend upwardly from the plate I 2 in the vicinity of the respective arms 22.
As the plate I2 is moved by the transmission mechanism 4 the respective pin 24 abuts against the adjacent arm 22. and thereby turns the collar 2i and the tube [6 therewith. In this manner the nozzle orifice 2'! is shifted angularly.
The intermittent shifting of the direction of the nozzle orifice 2'! is accomplished by the o'scil lating or rocking mechanism 3. The horizontal plate [2 has a pair of spaced brackets. 3| extended from opposite sides thereof, generally in the same direction as and under the diverging arms 22'. In the brackets 3| is journalled a pivot shaft 32. On the ends of the pivot shaft 32 are supported a pair of spaced lever arms 33. On the ends of the lever arms 33 adjacent and beyond the nozzle orifice 2'1, is supported a generally cylindrical container 34 extended transversely between said ends of the lever arms 33. At the top of the container 34 is provided a transverse slit opening 36 on the upper edge of which is provided a deflector 31 so that when said container 34 is in its extreme upward position, the deflector 31 intercepts the stream of water issuing from the nozzle orifice 21 and directs said water into the container 34 for filling said container rapidly.
Between the other ends of the lever arms 33 is mounted a cross plate 38. On this cross plate 38 is mounted a counterweight 39, which counterbalances the container 34 in such a Way that the container 34 is filled with water before the center of gravity of the oscillating or rocking device shifts from the side of the pivot shaft 32 nearer the counterweight 39 to the other side, for lowering the container 34 into the position indicated in dotted lines in Fig. 1.
The transmission 4 includes a ratchet 4| fixed on an enlarged portion 42 of the pivot shaft 32. A spring washer 43 between one of the brackets 3| and the shoulder of said enlarged portion 42 holds the other shoulder against the other bracket 3| with suflicient friction to prevent the rotation of the shaft 32 except when the ratchet 4| is rotated. Rotation is imparted to the ratchet 4| by a spring pawl 44 which extends from the weight 39. As the container 34 is filled with water and moves to the extreme down position, the rocking of the lever arms 33 and the turning of the counterweight 39 upwardly about the pivot axis urges the spring pawl 44 against the adjacent tooth of the ratchet wheel 4| so as to turn the latter and thereby to turn the pivot shaft 32. A worm 46 fixed on the pivot shaft 32 rides on a ring gear 41. This ring gear 41 is positioned under the head of the lower bushing 9 on the coupling 8. A firm coil spring 48 between the top of the threaded collar l and the ring gear 41 holds the ring gear 41 stationary with respect to the adjacent bushing 9. As the worm 46 is turned with the pivot shaft 32, it rides around the ring gear 41 and thereby turns the plate I2. The pin 24 engages the adjacent diverging arm 22 of the fixed collar 2| so as to rotate the nozzle tube l6 and the nozzle 25 therewith to the same extent angularly as the oscillating or rocking unit 3 is carried around the ring gear 41 by the pivot shaft 32.
On the lower portion of container 34 is an outlet orifice which is comparatively small so that it does not allow the outflow of the water from the container 34 fast enough to prevent the rapid filling of said container 34. Adjacent the outlet orifice 5| are provided a pair of suitable bearing ears 52 in which is journalled the pivot 53 of a butterfly valve 54. The outer flap of the butterfly valve 54 in the lowermost position of the container 34 as indicated in broken lines in Fig. 1, is engaged by a fixed plate 56 on the conduit 6, and is urged thereby toward the orifice 5| so as to partially cover said orifice 5| and thereby to control the rate of outflow from the container 34. During a period of time needed for the emptying of the water from the container 34, the stream from the nozzle 21 freely sprinkles upon the ground in the adjusted direction. After the container 34 has emptied sufficiently so that the center of gravity shifts to the side between the pivot shaft 32 and the counterweight 39, said counterweight 39 lifts the container 34 back to the initial extreme upward position where the container 34 is rapidly filled again for the swing to the downward position and for the next rotation of the nozzle assembly to another angular position. The nozzle assembly remains in said adjusted position throughout the period determined by the time needed for the emptying of the container 34. This period of time is predetermined by the relative position of the butterfly valve 54 to the outflow orifice 5|, which can be adjusted by suitably raising or lowering the plate 56.
Said period of time can also be predetermined differently for different angular positions of the sprinkler by bending a portion or portions of the rim of the plate 56 so that its effect on the position of the butterfly valve is different for different angular positions of the sprinkler.
The pivot shaft 32 and the worm 4| are rotated by the oscillation or rocking of said oscil lating unit 3 in one direction intermittently, and as the worm 4| meshes with the ring gear 41, the worm and the entire nozzle and rocking unit will turn around this gear 41, giving the entire assembly a slow intermittent rotation.
On the top of each lever arm 33 is provided a projection or lug 51 which abuts the adjacent tip 23 of the diverging arm 22 upon each return of the rocking unit 3 to the initial position shown in full lines in Fig. 1. In this manner the unit is always correctly aligned and centered with respect to the lower plate |2 for the next operation. For the purpose of the centering or aligning, the pins 24 are somewhat spaced from the adjacent diverging arms 22, to allow for this alignment action. Thus the inertia of the oscillating unit 3 is utilized to overcome the resistance ofiered by the friction under water pressure of the washer l8 on the bushing l4 and to align the diverging arms 22 with the pins 24 of the lower plate l2. This aligns the nozzle orifice 27 with the slit 36 of the container 34.
