LAWN -SPRINKLER.

Specification of Letters Patent.

Patented Aug. 31, 1909.

Application filed February 12, 1908. Serial No. 415,519.

To all whom it may concern:

Be it known that I, J osnrn: C. Kunz, citizen of the United States, residing at Fresno, inthe county of Fresno and State of California, have invented certain new and useful Improvements in Lawn-Sprinklers, of which the following is a specification.

My invention relates to hydraulic appliances and has special reference to sprinkling devices adapted to be attached to hose used in distributing water over lawns and gardens.

The chief objects of my improvements are to provide a water {sprinkling or spraying device for use with lawn and garden hose that will distribute the water in a suitable manner over a well defined oblong area or strip of the surfaceof a lawn or garden, instead of in circular patches concentric to the location of the hose nozzle, as is the common resultin all similar apparatus; to furnish a simple, efficient, and durable device for the purpose stated, and to supply a water spraying device that can be readily attached to hose in common use,-and, having few parts, can be economically manufactured. .1

I accomplish the above objects by means of the apparatus illustrated in the accompanying drawing which forms a part of this application and in which Figure 1 is a side elevation of my improved sprinkling device, attached to a base plate; Fig. 2 is a longitudinal section on the line 22 of Fig. 1, the base platebeing removed. Fig. 3 is a perspective viewof the deflecting vane; Fig. 4: is-a plan view of the blank for the vane, previous to beingbent into its final form; Fig. 5 is a top plan view of the stop, and Fig. 6 is a side eleva tion. of one of the pivot lugs.

Referring to the details of the drawing, the reference numerals 7 indicate a block or base plate, having a bore 8 provided with standard threads 8 for the attachment of an ordinary hose. The bore 8 extends to the center of the block and then passes upward through a nipple 9, provided with standard threads 9 A staple 7: serves for the attachment of a cord for shifting the block as required by pulling it along the ground.

The numeral 10 indicates a base, rectangular in outline, provided with a cylindrical projection or boss 11 which has a socket 11 furnished with threads adapted to engage the standard threads 9'" on the nipple 9. Concentric with said socket the base is bored for the insertion of a tube or nozzle 12 suitably reduced in size from the socket diameter to increase the initial velocity of the stream as it issues from the orifice 'of said nozzle. The nozzle 12 may be formed integral with said base if desired, but I prefer to insert a section of tubing, as illustrated in Fig. 2. Diametrically opposite each other upon the upper face of'said .base are erected standards 13, bent at right angles at the lower ends to form feet or flanges 14, and

secured to said base by screws 15. Between said standards and supported therein in a manner hereinafter described is located a deflecting plate or vane 16 formed of a single piece of metal, rectangular in outline as shown in the blank illustrated in Fig. 4 and approximately twice the length the part is to be when completed. The corners of the plate thus prepared are slightly clipped or rounded and extending through the extreme margins at the ends near each corner are formed slits or cuts 17, slightly inclined to the said margins. The corners of the plate 16 are bent on the lines 17 at a right angle with the plate surface, to form triangular flanges 18,,and the ends or flaps 19, formed by the cuts or slits 17, are curved in the same direction as'the said flanges 18 are bent, as shown at 20 in Figs. 2 and 3. The center of the blank 17 is provided with a diamondshaped opening 21 and thesaid blank is then bent upon itself-on the line 21 until the two parts are in apposition, back to back, as shown. The redundant projecting corners 18 may be removed so as to conform to the curve of the flaps 20 and show a finished 7 appearance as in Fig. 3. When the plate is thus bent upon the line 21, the central opening 21 will assume the appearance seen in Figs. 1 and 3, forming a triangular notch 22 in the lower edge of the plate 16 where folded. The said plate is furnished with lugs 23, having notches 23, which engage the lateral margins of said plate, and are swaged firmly thereon, serving a double purpose, of clamps to hold the laminae of the folded plate securely in apposition and also acting as journals or pivots, ,by engaging holes near the upper ends of the standards 13. By this arrangement, the said plate or vane 16 will swing to and fro upon its pivots23 in the supports 13 when acted upon same forces it will 'finer jets or films, and the by the stream from the nozzle 12, in a manner hereinafter set forth, the notch 22 affording suflicient clearance so as to interfere with the said nozzle. When in operation it is necessary to limit the vibrations of the said plate and to this end I provide a stop 24, which consists of a plate bent as at 25, the ends 26 being oppositely inclined as shown in Figs. 2 and 5, the angle of such inclination corresponding to the direction taken by the vane at each limit of its vibration,as shown in Fig. 2, where the said vane seen'in apposition with one stop flange 26, the alternate position of the vane being shown in dotted lines. The said stop member 24. isapplied to either standard 13 at a suitable height, the said bends or loops 25 engaging the marginsof the standard, and the device is then clamped firmly in place by the thumb screw 27. By moving the said stop 24 up or down upon the standard the oscillations of said vane 16 may be varied within sufficient limits.

Having thus described the details of construction of my improved spraying device I will briefly outline the method of its operation: The base can be readily applied to the nipple 9 of an ordinary hose coupling by screwing it thereon by hand, no wrench or other tool being required, since theoblong shape of the plate 10 affords a suflicient hand grasp. lVith the base thus applied, when a stream of water issues under pressure from the pipe 12 it will impinge against one face of the vane 16 and the stream will be slightly deflected following the face of the said plate, and upon reaching that part of the plate above the fulcrum or axis 23 the force of the stream will tilt the plate in the opposite direction. Being met upon this side by the immediately swing back again, and this vibration of the plate or vane will continue so long as the stream flows with sufficient pressure. The curved flanges or flaps 20-supplement and intensify the actionabove described, tending in addition to break the main body of the stream into side flanges 18 actto control the. deviation laterally, so that the distribution of the spray will be confined to a comparatively narrow oblong strip, instead of a circle as with ordinary sprinklers. This ability to send the spray in right lines, instead of concentrically, will be especially useful along walks and borders, and wherever the margins of the plate to be watered are straight, not only avoidingencroachment upon parts where the sprinkling would be objectionable but also serving to economize both :time and water.

Having thus described my invention what I claim is p 1. In a lawn sprinkler, the combination with a base adapted to be attached to a hose, and a nozzle, of an oscillating deflector having its axis intersecting the axis of said nozzle, said deflector adapted to be oscillated by the stream from said nozzle.

2. In a lawn sprinkler, the combination with a nozzle of a plane deflector adapted to be oscillated by the impact of the stream from said nozzle, said deflector having its axis intersecting the axis of the nozzle, and means for limiting the oscillating movements of the deflector.

3. In a lawn-sprinkler, the combination with a nozzle, of a deflecting vane mounted to oscillate upon an axis intersecting the axis ofsaid nozzle, said vane adapted to be operated by the imnact of the stream from the nozzle, and an adjustable stop for limiting the movements of said vane.

41;. In a sprinkler adapted to be attached to a base plate, thecombination of a nozzle, a vane mounted to swing upon an axis at a right angle to the longitudinal axis of said nozzle, a stop for limiting the oscillation of said vane,.and means for adjusting said stop.

5.111 a sprinkling device adapted to be usedwith a hose, the combination of a supporting base, a nozzle, a vane arranged to swing upon an axis transverse to the axis of said nozzle, lateral flanges for the vane, and an adjustable stop for limiting the oscillations of saidvane.

6. In. a sprinkler including a base-plate adapted to be attached to a nozzle, an oscillating-vane adapted to be operated by the impact of the stream from the nozzle, supports for the vane attached to the base-plate, and a stop adjustable on one of said supports.

7; In a spninkler, including a base-plate adapted 'to be attached to a nozzle, an oscillating vane adapted" to be operated by the impact of the stream from the nozzle, said vane consisting of a rectangular memben formed of'a single plate bent upon itself in the median line, andha'ving the endsof the bent plate curved in opposite directions, and side flanges bent at right-angles with the main plate, supports for the vane mounted on said base-plate, anda stop for limiting theosci lla-tion of said vane.

In testimony whereof-I aflixmy signature in the'prcsence of two witnesses.
