MORTON G. BUNNELL OF CHICAGO, ILLINOIS, ASSIGNOR TO FREDERICK O. AUSTIN, OF SAME PLACE.

SPRINKLER.

SPECIFICATION forming part of Letters Patent No. 549,955, dated November 19, 1895.

Application filed September 24, 1894. Serial No. 523,929. (No model.)

.To aZZ whom it may concern.-

Be it known thatLMoRToN G. BUNNELL, a citizen of the United States, residing at Chicago, in the county of Cook and State of lllinois, have invented a certain new and useful Improvement in Sprinklers, of which the following is a specification.

A prominent object of my invention is to vary the thickness of a sheet of water discharged from the nozzle of astreet-sprinkler and to cause the thicker portion of such sheet to be the lateral or side discharge in contradistinction to the downward discharge. By thus discharging the greater volume of water laterally, undue wetting of the street at a point below the nozzle is avoided.

A further object is to provide a simple and effective cut-off or regulating device whereby any portion of the discharge can be cut off.

Further objects are to provide a simple, effective, and economical construction of Valve and to avoid the collection of dirt within the nozzle.

To the attainment of the foregoing and other useful ends my invention consists in matters hereinafter set forth.

In the accompanying 1 drawings, Figure 1 represents in side elevation a street-sprinkling wagon with my improvements applied. Fig.- 2 is a plan of portions of the devices for operating'the'valve and the cut-off. Fig. 3 shows the nozzle in end elevation with the valve closed. Fig. 4 is a like view With'the valve removed. Fig. 5 is a vertical section on line w a; in Fig. 3. Fig. 6 is a longitudinal section on line y y in Fig. 3.

In the sprinkling-wagon shown, the tank A is arranged upon the wheeled wagon-body B, and a seat 0 for the'driver is arranged in front of the tank. The sprinkling-nozzles (whereof one is illustrated) are arranged to discharge the water in sheet form ina plane between the front and rear wheels of the wagon, and means for opening, closing, and varying the discharge are arranged under control of the driver. Itis understood, however, that the sprinkling-nozzles could discharge back of the rear wheels, if so desired, and also that my invention can be usedin connection with a two-wheeled cart as well as with a wagon.

The nozzleD is provided with an outwardlyopeningvalve E, which is hinged upon the nozzle and arranged to seat against the end of the same so as to cut oif the discharge. The nozzle is open at its end, so as to provide it with a mouth or port 1, and the valve is external to the nozzle, whereby it can be closed against the end of the nozzle, so as to cutoff the discharge, as in Fig. 5, or be opened outwardly or away from the ported end of the nozzle, as in Fig. 6, so as to permit the water to discharge in sheet form through the space between the rear side of the valve and the annular valve-seat 2 formed by the end of the nozzle.

As best shown in Fig. 3, the valve is hinged at one side of the nozzle, said side being the one nearest the longitudinal middle of the wagon, so that when the valve is open, as in Fig. 6, the space or opening between the rear edge portion of the valve and its seat 2 will be greatest at a point farthest from the middle line of the wagon and will from such point contract toward said middle line. By such arrangement the valve opens obliquely or at an angle to the plane of its seat, and thereby permits the lateral dischargeof water to have a greater volume than the discharge that takes place downwardly from the nozzle. In other words, the sheet of water issuing from the nozzle will be thickest at the side of the nozzle which is opposite the side whereat the valve is hinged, and said sheet of water will diminish in thickness from the aforesaid point toward the side of the nozzle at which the valve is hinged. In this way an excess of water discharging downwardly from the nozzle onto the street will be avoided, and at the same time a suitable volume will be given to the discharge which is projected laterally in a direction away from the side of the wagon.

In Figs. 4 and 5 I have shown a deflector F, arranged within the nozzle and positioned to deflect the water away from such spaceas I may occur between the Valve and the nozzle end2, at and adjacent to the-upper portion of the nozzle, thereby avoiding an upward discharge when the valve is open. 7 As a matter of course, the space between the open valve and the nozzle end, at 3, in Fig. 6, will be diminished proportionately to the nearness of the valve-hinge to the end of the nozzle; but I prefer setting the pintle 4 of such hinge away from the end of the nozzle to some extent. The employment of the deflector is, however, preferable, and under the arrange ment best shown in Fig. 4: the deflector prevents the discharge of water vertically upward and also in a direction upwardly at an inclination toward the tank or body of the wagon.

The deflector consists of an inclined shield held within the nozzle, and as a desirable construction said deflector may consist of aflexible shield or plate 5, bolted upon a bed-plate of holder (3, arranged within the nozzle and either secured thereto or formed integral with the same. The flexible and desirably-elastic shield or plate 5 may be held so as to project out from the mouth of the nozzle when the valve is open, in which way it will maintain its contact with the open valve and be bent back within the nozzle when the valve is closed.

In order to cut oif as much of the lateral discharge as may be necessary in sprinkling near a sidewalk or in passing a pedestrian, the nozzle is provided with an adjustable cutoff G, consisting of a rotary adjustable ring 7 arranged upon the nozzle and having a segmental portion 8, which laps over a portion of the annular edge of the valve. The ring 7 could be held upon the nozzle in any suitable way; but as a matter of furtherimprovement it is arranged to screw upon the nozzle, so that when it is turned in a direction to bring it over the under portion of the space between the open valve and valve-seat it will work toward the end of the nozzle, and thereby cause the segment to effectively cover the width of the space or gap over which the lat ter is caused to project. The rear side of the valve is desirably provided with a gasket or packing-ring 9, and the ledge or segment 8 is likewise desirably provided with a packing rib or strip 10, which latter engages the annular edge of the valve.

The valve E opens against the resistance of a spring, which, broadly considered, may be arranged and applied in any desired or suitable way. In Fig. 1 the spring H, which is adapted to oppose the opening of the valve with a yielding elastic resistance, is applied to the device or valve-movement employed for opening the valve. The valve-movement shown in said figure comprises a lever 1.1, fulcruined at 12 upon an arm 13 and having its short arm connected with the valve. The long arm of said lever is hinged to a rod 14, which latter extends forward and connects with the crank-arm 15 of a rock-shaft 16, which latter carries a treadle or foot lever I. With such construction the spring can be arranged on rod 14: and confined between a shoulder 17 on said rod and fixed stop 18 on the body of the wagon. By the foregoing arrangement the long arm of the lever 11 is subj ect to the spring, and hence when the valveopening device is released by the driver the spring will serve to effectually close the valve against the pressure of the water, and on the other hand the driver can readily open the valve by depressing foot-lever l. The cutoif G can also be adjusted by the driver, and to such end a rock-shaft K is arranged upon the wagon-body and provided at its ends with. arms 19 and 20, projecting laterally in opposite directions. Arm 19 of said rock-shaft connects with the rotary adjustable cut-elf by a link 21, while arm 20 is connected with a foot-lever or treadle 22 by a link The cut-off normally occupies about the position shown in Fig. 3, from which position it can be shifted round to cut off the side discharge, heretofore referred to, bydepressing the forward or foot portion of lever 22. Any suitable latching or locking device can be employed in conjunction with lever I, and said lever can be arranged to be operated by hand or by foot power.

The nozzle connects with the water-tank A by a pipe 24 and is shown attached to a support or bracket 25, arranged to depend. from the body of the wagon.

\Vhat I claim as my invention is 1. A street-sprinkler comprising a cart or wagon provided with a water-supply tank, a nozzle D suitably connected with the supply tank, a hinged valve E arranged to close against and open outwardly from the end of the nozzle, and suitable-valve operating means connected with the valve and under control of a driver upon the cart or wagon, said valve being hinged at one side of the nozzle adjacent the longitudinal axis of the cart so that when it is open the portion of the sheet of water discln rging laterally from the nozzle will be thicker than the portion of such sheet discharging downwardly, substantially as described.
