LAWN-SPRINKLER.

SPECIFICATION forming part of Letters Patent No. 691,419, dated January 21, 1902. Application filed March y8, 1901. v Serial No.. 50,360. (No model.)

- T all whom, it may concern:

Beit known that LADDISON VANDERvooRr, a subject of the King of Great Britain, residing at Belleville, in the Province of Ontario and Dominion of Canada,have inventeda new and useful Lawn-Sprinkler, of which the following is a specification.

This invention relates to lawn-sprinklers;

and the primary object of the invention is to provide a simple, reliable, and eicient sprinkler which is self-regulatingandadj ustingand for that purpose provided with suitable actuating mechanism and gearing whereby the nozzle of the sprinkler is revolved or swung through a horizontal orbit, as wellas deiiected from a vertical to a horizontal position, and vice versa. By this means the sprinkler is adapted to cover a large area of one hundred feet in diameter, more or less, thoroughly wetting and sprinkling the entire surface within such area.

Y It is also an object of this invention to providemeansforeftec'tuallyregulating the speed at which the mechanism of the sprinkler is actuated by providing a regulating device which governs the amount of water or size of the impact-stream which is utilized to impart rotary motion to the water-motor wheel from which the remaining parts ofthe lawnsprinkler are driven.

A further object of the invention is to provide a novel form of supporting-base for the lawn-sprinkler,which is adapted to be used in connection with a series of detachable bracearms, which can thus be removed when the machine is not in use to render the machine as a Whole more compact for transportation and storage.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination, and arrrangementhereinafter fully described, illustrated, and claimed.

In the accompanying drawings, Figure l is a perspective view of a lawn-sprinkler constructed in accordance with the present invention. Fig. 2 is a side elevation of the same. Fig. 3 is also a View in elevation of thesprinkler, taken at right angles to Fig. 2. Fig. 4L is a detail perspective view of the supporting-base, showing the tubular standard,

the supply-elbow, and the regulating device for the propelling-stream. Fig. 5 is a detail sectionalview of the regulating device. Fig. 6 is an enlarged detail longitudinal section through the nozzle, showing the means for swiveling the pitman thereto. Fig. 7 is a detail perspective view of the bracket which is flat disk, as best illustrated in Fig. 4, which base is provided with a tubular standard 2, extending upward therefrom and preferably arranged centrally thereof, said standard forming a part of the tubular connection with the discharge-nozzle. Communicating with the lower end of the standard 2 is a supplyelbow 3, projecting at its outer end beyond the periphery of the supporting-base l and threaded, as at 4, to receive the coupling of a suitable hose Wherewith to supply water to the elbow 3 and tubular standard 4. preparatory to delivering the water to the nozzle hereinafter described.

The base l is provided with a series of peripheral notches 5, which are crossed by overlying and underlying arcuate straps 6, which, together with the notches, constitute a plurality of radially-disposed sockets for the reception of a corresponding series of detachable brace-arms, usually in the form of round Wooden sticks. (Clearly shown in Fig. l.) These brace-arms serve to provide a broad bearing for the sprinkler las a whole and effectually prevent the sprinkler from tipping over under the action of the stream of water forced therefrom under pressure.

Surrounding the tubular standard 2 and journaled thereon is a Water-motor Wheel 7, comprising a cylindrical central portion 8, with outwardly-extending parallel flanges 9, between which are secured a circular series of blades lO, having their outer extremities deected rearwardly with respect to the direction of rotation of the Wheel and adapted to receive the impact of a stream of Water which is delivered from an upstanding nipple ll, communicating with the supply-elbow 3 and preferably extending across Within the IOO elboW 3, as shown in Fig. 5, where it is provided with an opening 12 to receive a portion of the inflowing supply of water. The upper end of the nipple 11 is internally screwthreaded to receive an externally-threaded regulating-tube 13, which is provided in one side with a longitudinal slot 14, forming the discharge opening for the water passing through the nipple. The tube 13 is surrounded by a regulating cap or cut-off 15, which has a screw-threaded engagement therewith and which may be adj usted lengthwise of the tube 13 for closing the discharge-opening 14 to any desired extent for the purpose of regulating the size and strength of the impact-stream which acts upon the blades of the motorwheel. The tube 13 is provided at its upper end with a milled head 16 to facilitate the turning thereof, so as to move the lower end of the slotted opening 14 below the upper extremity of the nipple, said expedient also serving as a means for regulating thesize and strength of the stream which actuates the lower wheel. The upper end of the tube 13 is internally threaded to receive a threaded plug 17, which may be removed for the purpose of iushing out the tube 13 and freeing the same from any sediment which may accumulate therein.

In journaling the Wheel 7 upon the tubular standard 2 said wheel is provided with a centrallyarranged upstandin g sleeve 18, and said sleeve is encircled by a thread 19, forming a worm which meshes with the teeth of a nozzle-turning worm-wheel 20, the said worm-Wheel being journaled upon a studaxle 2l, carried by the outwardly-projecting arm 22 of a ring or collar 23, which surrounds the tubular standard above the sleeve 18 of the motor-wheel and is held in place by means of a binding-screw 24, so as to prevent rotation thereof. Fixedly connected to the wormwheel 20 is a driving-worm 25, and under the preferred embodiment of this portion of the invention the Wheel 20 and worm 25'are rigidly mounted upon a sleeve 26, which is journaled on the stud-shaft 21,`the arrangement being best illustrated in Fig. 3.

Superimposed above the motor-wheel 7 is a rotary disk 27, which is provided on its under side with a crown-gear 28, the teeth ofl which are engaged by the Worm 25, as illustrated in Fig. 3. The disk 27 is provided with a central depending hub portion or vcollar 29, which is seated upon the ring or collar 23 and is adapted to rotate thereon. The disk 27 forms a support for an upstanding bracket 30, comprising parallel arms 3l, which receive a crank-shaft 32, upon which is journaled a nozzle-deflecting worm-wheel 33, said wheel being interposed between the arms 31 and having its teeth in engagement with a worm-thread 34, formed on the outer surface of a tubular plug 35, constituting a detachable extension of the upper end of the standard, the said plug fitting tightly by friction into the upper end of the tubular standard 2, as best illustrated in Fig. 1. As the tubular standard 2 is non-rotatable, the tubular extension 35 thereof willi also be held stationary and a rotary motion will be imparted to the wheel 33 by reason of the fact that said wheel is moved in a circular path around the standard, while its teeth always remain in engagement with the worm-thread 34.

The discharge-nozzle 36 is connected with the extension or plug 35 by means of a piece of flexible hose 37, and in this way the nozzle is flexibly connected to the tubular standard, so that the nozzle may bek deected from the vertical. The body 38 of the nozzle is provided with a fixed collar 39, and the removable portion of the nozzle 36 is also provided with a collar 40, while lying between said collars is a ring 41, which is provided at one side with a tangentially-disposed cross-head 42, upon the opposite ends of which are journaledl a pair of sleeves 43, carried by the forked upper end of a pitman 44, the lower end of which is also forked and the arms thereof provided with bearing sleeves 45, which embrace the crank-pins 4G of a pair of cranks 47 at the opposite ends of the crankshaft 32, upon which the nozzle-deflecting worm-wheel 33 is lixedly mounted.

From the foregoing description it will be understood that the motion imparted to the motor-wheel 7 by means ofthe propellingstream from the nipple 11 is communicated to the disk 27 by means of the worm-thread 19, the worm-wheel 20, the driving-worm 25, andthe crown gear 23. The supportingbracket 3f.) is thus caused to revolve around vthe tubular standard, and by reason of the specific connection between said bracket and the discharge nozzle the nozzle is carried around through a circular path. As the nozzle-delectiug worin-wheel 33 revolves around the tubular standard the teeth thereof are engaged by the thread 34, and a comparatively slow rota ry motion is im parted to the crankshaft 32, thereby slightly revolving the cranks 47 and by means of the connecting-pitman 44 depressing or elevating the discharge-nozzle. It will thus be seen that the nozzle is simultaneously revolved and deflected and that both operations are automatically performed without any attention on the part of the operator and by the motion derived from the water-motor wheel 7. The speed at which the motor-wheel is driven is governed by the impact-stream, which may be regulated by the means described.

In the use of the sprinkler it is only necessary to set the sprinkler in the center of the area to be sprinkled and apply the supplyhose and brace-arms thereto. After adjusting the propelling-stream to give the required speed to the motor-wheel the device will operate automatically to sprinkle the entire area within the limits ofthe outer circle.

From the foregoing it is thought that the construction, operation, and many advantages of the herein described invention will IOO IIO

be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to Without departing from the spirit or sacrificing any of the advantages of the invention.
