THCMAS C. BONNETTE, OF BAY CITY, MICHIGAN.

LAWN-SPRI'NKLER.

SPECIFICATION forming part of Letters Patent No. 461,415, dated october 2o, 1891.

Application filed April 16, 1891. Serial No. 389.174- (NO mOdeJ- -To a/ZZ whom it may concern! Be it known that I, THOMAS C. BONNETTE, a citizen of the United States, residing at Bay City, inthe county of Bay and State of Michigan, have invented certain new and useful Improvements in Lawn-Sprinklers, rof which the following is a specification, reference being had to the accompanying drawings.

My invention relates to improvements in lawn-sprinklers, and pertains to that class of sprinklers in which a jet of water under pressure is distributed in the form of a spray over the lawn byrapidly-revolving blades; and the invention consists in the combination, arrangement, and location of the parts, together with the operation ofthe same, as I shallpresently explain in detail, and which will be also explicitly defined in the claims of this speciof my improved lawn-sprinkler, partly sec-` ication.

The object ot the invention is to provide a device ot the class mentioned which will be durable and not liable to wear so as to become inoperative in a short time.

Another object of the invention is to provide devices for distributing the water over a semicircular area upon one side of the distributing-point, whereby the water maybe distributed from a point near a walk, fence, or building without wetting the same.

' Another object is to provide devices for sprinkling lawns which may be easily changed for sprinkling either a circular or a semicircular area, as desired, and which is not liable to become clogged or choked up, and which can also be easily manipulated and handled.

My invention is illustrated in the accompanying drawings, in which Will be found the saine letters of reference indicating like parts throughout the several views.

Figure l represents a side view in elevation tional, and arranged for distributing Water over a circular area. Fig. 2 is a vertical section of the same, showing the parts arranged for distributing water over a semicircular area. Fig. 3 is a plan view of Fig. l. Fig. 4 is a vertical section of the jet-pipe and of the lower support of the distributing-wings. Fig. 5 is avertical section of the upper support of the distributing-wings. Fig. 6 is a horizontal section of Fig. l, taken at was. Fig. 7 is a horizontal section of Fig. 2, taken at y y. Fig. 8

shows the upper portion of Fig. l with the distributing-Wings in a different position.

o. is a casing inclosing a chamber b, and this casing is provided with a hose connection c, ot' the usual form, to which is secured a hose d, leading from a hydrant or suitable means for obtaining water-pressure, and e is a standard arranged to be stuck into the soil of a lawn for supporting the casing. The upper side f of the chamber is provided with a short upwardly-projecting delivery pipe or nozzle g, having an opening h to the chamber, and this nozzle is preferably located slightly to upwardly-projecting stud 'L'.

j is a sleeve having a central longitudinal opening k arranged to tit over either the noz-A zle g or the stud t', as desired, andlare curved win gs arranged with a downwardly-proj ectin g thin edge or web m, centrally located transversely with the upper end of the opening la, so as to divide the opening and provide a free exit for the water on. both sides of the web against the curved and vertically-inclined concave inner side n of the wings.

o is a vertical spindle rigidly secu red to the upper side of the web m in vertical alignment with the opening 7c, and p are braces secured by their lower ends to the part f, and, extending above the Wings Z, are secured by their upper ends to a head-piece q. This headpiece is provided with openings .r and o, in vertical alignment with the nozzle g and the -upper end s ot' the spindle is engaged, the end of the spindle being irst passed into the desired opening from beneath, and then the sleeve is passed downwardly over the nozzle orv the stud in alignment with the opening, the spindle being held in position by a bar t, which is pivotally secured upon the head q, and which when turned across the openings r and o forms an end bearing for the spindle and prevents a longitudinal movement thereof, a catch 'a being arranged upon the head for engaging with a recess w in theend portion of the bar to retain it in position over the openings, but which will disengage for allowvIo The spindle being placed in the opening o, with the sleeve j over the nozzle g, as shown in Fig. l, water under pressure is admitted through the hose to the chamber b and through the nozzle into the sleeve against the web m, which divides the stream and directs one-half thereof against the concave outwardly-inclined inner surface fn, of each wing Z, which causes the wings and spindle to revolve rapidly and distribute the water over a circular area in a tine spray, as shown in Fig. 6, the spindle being lifted by the force of the water to bear its ends against the bar t, which provides a small area for frictional contact,

while the lower end of the spindle is retained in place by the sleeve j revolving around the nozzle.

It will be seen that by this construction the action of the web m is to divide the `water column which passes solidly through the nozzle and start each portion 4or stream on a whirling action, which is accelerated and turned in an outward direction by the inclined surfaces and the rotary motion of the blades, which breaks the stream into minute drops, so that the water is distributed evenly and in a fine spray over'a great area, there being no obstruction or reduced orifices to reduce the force or speed.

As shown in Figs. 2 and 7, the spindle o is placed in the opening r, with the sleeve jsurrounding the stud t', and the stream of water then leaving the nozzle is caught by the web 'm as each radial portion thereof passes over the nozzle, and the face of the stream causing the wings to revolve with great rapidity the water is directed outward in a tine and broken spray and distributed over a semicircular area only, the web m on passing the nozzle shutting the stream from further contact with the preceding wing, so that one wing only will be acted upon by the water at a time and over the same portion of their revolution, so that each succeeding wing as it passes over the nozzle will distribute the water over the same semicircular area, and by this arrangement the device can be placed neara walk and distribute the water over an area of which the edge of the walk is the radial line, so that the walk will be left entirely dry, and passers-by will not be annoyed by stray jets or drops of water flying in'their pathway, and the same advantage is gained in placing the sprinkler near a building or fence, as the device then will distribute the water over the lawn without wetting the adjacent building.

Having described the construction and opa vertical axis above the sleeve and provided with concave and upwardly -inclined under surfaces having their lower portions merging into the lateral surfaces of the web, substan tially as set forth.

2. Thecombination, ina lawn-sprinkler, of the nozzle g, the sleeve t@passed over the nozzle, the wings Z, having the outwardly and upwardly inclined surfaces n and joined together at their -base by a web fm, secured diametrically across the said sleeve, a spindle o,

extending above the wings in vertical alignment with the sleeve, and means forsupporting the upper end of the spindle, substantially as described.

3. In a lawn-sprinkler, the combination ofthe wings provided at their base with a transverse web m and with the upwardly-inclined concave under side n and mounted on a centrally-located pivotalsupport, and a nozzle g, located on one side of the said pivotal support, for the purpose set forth, substantially as described.

In testimony whereof I hereunto ax my signature in the presence of two witnesses.
