ADELBERT G. GUMAER AND JOHN G. W. KNOLL, OF BUFFALO,NE\V YORK.

SERPENTINE LAWN-SPRINKLER.

SPECIFICATION forming part of Letters Patent No. 374,960, dated December 20, 1887.-

v Application filed August 2G, 1887. Serial No. 247,967. (No model.)

To all whom it may concern.-

Beit known'that we, ADELBERT G. GUMAER and'JoHN G. W. Kuoni., of the city of Buffalo, county of Erie, and State of New York, have invented certain new and useful Improvements in Serpentine Lawn-Sprinklers, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure l is a View of our sprinkler attached to the end of a hose pointing upward and.4

with the ends of the sprinkler-nozzles open. Fig. 2 is a view of the sprinkler attached to the end of ahose pointing downward and with the ends of the nozzles closed. Fig. 3 is a section of a hose and coupling for attaching our sprinkler, showing the perforated plug and the manner in which we may connect the flexible tubes to it; and Figs. 4 and 5 are sectional views of the nozzles of the sprinklers detached.

The object of our invention is to produce ay lawnsprinkler that shall thoroughly distribute water in various small streams or jets and drop it all over a certain circular area as nearly like rain as practicable, and at the same time present a unique and attractive appearance and be convenient to apply in use. To this end we provide aserpentine sprinkler to be connected to an ordinary hose or other device containing water under pressure, in the manner illustrated in the drawings, and hereinafter described.

Our invention consists in the combination of parts for particular improvement of such a sprinkler, succinctly stated in our claims.

We mean by the phrase serpentine sprinkler7 a sprinkler that in action moves very much like a serpent fastened by its tail and wriggling and springing about in a frantic endeavor to get away, and such is the appearance and action of our sprinkler. As it 'is composed of several small wriggling serpentine tubes or sprinklers in a bunch, it presents a life-like appearance that arrests attention and interests spectators and forms a considerable feature of the practical utility of the device in operation, because in practice the device is placed in show-windows and other conspicuous places for display and advertising purposes.

cap adapted to screw on over the couplingB I and to bear upon the top of the plug C and force it tightly into the coupling B.

F designates small hardrubber or other suitable tubes,which are firmly secured within the holes D of the plug C. rlhese tubes are chaniiered at f to prevent their cutting the small flexible or serpentine rubber tubes G, which are secured to them. The tubes F are also provided with an annular roughened projection, f 2, to make a firm connection with the tlexible tubes G, as shown in thevdrawings. The tubes F might be omitted and the tubes G be made a part of or connected to the plug C. The tubes G are provided with nozzles H, made of hard rubber or other suitable material, and provided with one or more small openings, as illustrated, either in the end or at one side, or both.

I indicates a small screwsplug adapted to close the end hole in the nozzle H and cause the water to escape from the side hole, which is always open. Whenever the end hole is open, the water will escape there as if there were no side hole, because it will not change its direction to pass out of the side hole.

K indicates an annular projection upon the nozzle H for connecting it securely to the serpentine tube, as represented in the drawings. The result of this construction is that our improved serpentine sprinkler can be readily at. tached securely to place for operation, and it is not likely to wear out or get out of order.

The operation is as follows: lThe plug C, when in place, checks the iiow of water from the hose A, and as the openings through the plug and through the serpentine tubes are smaller in combined transverse area than the opening in the hose the result is that the pressure of water is increased and the water spurts out of the nozzles of the serpentine tubes in small streams with considerable force.

IOO

The effect is to make the serpentine tubes Wriggle and gyrate or dance about in the air in a very comical manner and in a very effective manner for sprinkling purposes. The Water is tossed about in the air in an inlnite variety of directions and separates into drops and falls all over the ground exactly like rain. A circle of about t-Wenty-iive to forty feet in diameter, according to the force of water-pressure, can be thoroughly sprinkled.

The serpentine sprinkler thus Works automatically, but Without driving any machinery in the ordinary Way, and hence is economical and efcient without being` liable to Wear out or get out of order, because it contains no re- -volving wheel or othervlike mechanism, and

it is a great practical advantage to provide,as illustrated, for the use of several wrigglers or sprinklers in a bunch.

Having described our improved serpentine sprinkler, what we claim to be new, and desire to secure by Letters Patent of the United States, is-

1. In a serpentine sprinkler, the combina tion of a tapering perforated plug, C, adapted to be forced into the end ofa hose or the like, with tubes F, secured in holes in the plug, exible serpentine tubes G, secured to the tubes F, and nozzles H upon the free ends of the flexible tubes, substantially as set forth.

2. In a serpentine sprinkler, the combination of the internally screw-threaded cap E, adapted to fit over the coupling B, the tapering perforated plug G, forced into thecoupling B by the cap E, and the flexible serpentine tubes G, secured in the plug C and provided with nozzles H, substantially as set forth.

3. In a serpentine sprinkler, the combination of a tapering perforated plug, C, adapted to beforced into the end ofa hose or the like, and the feXible serpentine tubes G, connected therewith and provided with the nozzles I-I, substantially as set forth- In testimony whereof We have hereunto subscribed our names.
