No.474,465. Patented May 10, 1892.

Unrrnn STATES PATENT @unica EUGENE T. IVESTERFIELD, OF NEW YORK, N. Y.

STREET-SPRINKLER.

FJEECIFICATION forming part of Letters Patent Ni'o. 474,465, dated May 10, 1892.

Application filed January 27, 1892. Serial No. 419,381. (No model.)

To CZZZ whom, it may concern.'

Be it known that I, EUGENE T. IVESTER- FIELD, a resident of the city of New York, in the county and State of New York, have invented an Improvement in Street-Sprinklers, of which the following is a specification, reference being had to the accompanying draw'- ings, forming a part hereof, wherein- Figure l is a side view, partly in section, of my improved street-sprinkler. Fig. 2 is an enlarged vertical central section of the sprink ling-nozzle, the line 2 2, Fig. 3, indicating the plane of section. Fig. 3 is a top view of said nozzle; and Fig. 4 is a side view, partlyin section, of a modified form of nozzle.

This invention relates to a new construction of nozzle for street-sprinklers 5 and it consists in the novel combination and arrangement of parts hereinafter more fully described.

In the accompanying drawings, the letter A represents a watering-tank of usual or suitable construction mounted on wheels or otherwise for convenience of transportation. From the tank A extends a Water-discharge pipe Ct, which at its discharge end is turned upward, as shown in Fig. l,and properly connected with a discharge-nozzle B. This nozzle may for convenience of construction and security be further rested upon a platform l), which is suspended from the rear part ofthe truck that carries the tank A. The nozzle B, of which a more complete representation appears in Fig. 2, consists of a lower tube CZ, an upper sleeve e, and a central plug f. The lower tube CZ is simply an extension ofthe Clischarge-pipe a and has its upper end throughout on the same plane. It may be provided with a projecting lip g to assist in spraying the Water; but this lip may be omitted and does not involve any feature of my present invention. The upper sleeve e is vertically movable and is so shaped that part of its circumference is shorter than the other part. Thus in Fig. l the part marked e2 is the short portion and the part marked e3 is the longer portion of the sleeve e. The longer portion of the sleeve e (being the portion es) is adapted to overlap the upper part of the tube CZ-that is, to embrace the same-while the shorter portion e2 is adapted to rest on top of the tube CZ, a packing-ring of leather or the like ZL being, if desired, attached to the lower end of the short portion e2. Vitliin the sleeve e is the adjustable plug f, which can be screwed higher or lower and which, as will be hereininafter shown, regulates by its position the amount of water allowed to reach the outletopening. The sleeve e can be moved up and.

down to a greater or less extent by means of a lever D, and to which it is connected, as shown in Fig. l, by a link or rod i or by analo gous means.

As far as the mechanism has now been described, it will operate as follows: By turning the plugf more or less down the amount of water admitted to the outlet-opening can be regulated, because the plug enters into the tube CZ to the extent indicated in Fig. 2, so as to regulate the ow from CZ. After the amount of water admitted to the outlet has been regulated by the adjustment of the plug the outlet-opening itself can be regulated by raising the sleeve c to a greater or less extent, and thus by the use of the adjustable sleeve having the inner adjustable pluglcan let asmall body of water flow through a large outletopening or a large body of water through a small outlet-opening and thus regulate the character of the stream issuing from the sprinkler. The outlet-opening itself is formed whenever the short portion e2 of the sleeve e is lifted away from the upper end of the tube CZ. Instead of constructing the sleeve of one short piece e2 and one long piece e3 it may be constructed of series of short pieces and series of intervening longer pieces with substantially the same effect-that is to say, the longer pieces guide the sleeve in its up-anddown motion and prevent water flowing out where the longer pieces are, the shorter pieces being, when lifted off the tube CZ, the orificeforming inst-rumentalities.

In the modification which is shown in Fig. 4 the sleeve e is screwed to the tube CZ and contains, also, the adjustable plug f. By adjusting' the sleeve e higher or lower the outlet-orifice will be regulated, and by adjusting the plugf the amount of Water admitted to the orifice will be regulated. In the modified form shown in Fig-.1t it is desirable to provide the pipe a with a shut-off j, which can bacontrolled by a lever K from the drivers seat;-

Referring once more to Figs. 2 and 3, I call IOO attention to a set-screw or pin Z, which projects from the tube (Z through a slot in the longer portion of the sleeve e, so as to limit the up-and-down motion of said sleeve, and preventits being pulled entirely ott the tube CZ.

Having described my invention, I claiml. The combination of the Water-discharge pipe a, terminating in the tube CZ, with a sleeve e, means for vertically adjusting the said sleeve, and with an adjustable plug f Within said sleeve, all arranged so that the size of the outlet-orifice is determined by the motion of the sleeve e and the amount of Water admitted to said outlet-opening is determined by the plug f, substantially as herein shown and described.

2. The combination of the tube CZ with the vertically-movable sleeve e, having long portion e3 and short portion e2, the short portion resting on the tube CZ, and with the vertically- 2o sleeve, all as and for the purpose herein shown 3o and described.
