SPECIFICATION forming part of Letters Patent No. 487,804, dated December 13, 1892.

' Application filed March 19,1892. serial 1%, 425.587. on model.) 7 1 To all whom, it may concern.-

Beit known that we,HENRY '1. WALSHEand MATT EW SALLENGER, citizens of the United I States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in StreeflSprinklers; and we do hereby declare .the following to be a full, clear, and exact descript-ion of the invention, such as will enable others skilled in the art to which it appertains to make and use .the same, reference being had to the accompanying drawings, and

to figures of reference marked thereon, which 1 form a part of this specification.

This invention relates to. improvements in.

sprinklers, particularly that class employed on watering-carts for street purposes. 1

Our invention consists in the peculiar con 1 from the foot-board.

' Briefly described, the sprinkler consists iotacylindricalshellinwhich arecontainedavalve and valve-seat, together with a gate. The

valve admits water from the cart to the sprinkler, while the gate controls the discharge-orithe length, of the disohargeorifice may be readily-adjusted, as circumstances require.

Other minor features of construction will hereinafter be fully described and explained.

The drawings represent in Figure 1 an end view of a watering-cart fitted Will] a sprinkler embodying our invention. Fig. 2 is a front view in elevation of a left-hand sprinkler. Fig. 3 is a longitudinal vertical section. Fig. 4: isa transverse section vertically, and Fig. 5 is a side elevation.

In the accompanying drawings, 2 represents the sprinkler as an entirety, composed of a cylindrical shell 3, adapted to be connected with a discharge-pipe 4 from a tank 5, suitably mounted upon a traveling cart. This shell is exteriorly fitted with a removable closing cap 6 and formed with a circumferential aperture 7, which serves as the dischargeorifice. Said aperture extends only in part about the circumference, and its inner limit is such that the spray is directed obliquely toward a second spray from a co-operating fluid-openings 12. ated} to hold it normally closed against the sprinkler similarly mounted on the other side of the cart. These two sprays are to intermingle,in order to wet that partof the street directly beneath the center of the cart as it progresses. The outer upper limit of the ori- "fice is to terminate at such point as to give the water, prominent among which is the fact that the point where the water is delivered is alwaysafixed one and not dependent on the head'of water in the tank. Its advantages are apparent, since the driver in passing over foot-crossingsv can shut off the water at the proper moment. Moreover, the vertical spray laterally of the cart can be more readil y con,"

trolled, particularly when the proximity of open car'sfcarriages, or the curb requires a diminution in the area and extent of the spray. I Thewater-controllingdevicesinthissprinkler com prise a valve 9, adapted to close upoii a transverse partition or valve-seat 10 with This valve is spring-actutank-pressure, While the valve-stem 13 extends {through and beyond the cap, its projecting" end'havingacam-leverlt mounted thereupon, which co-operates with a cam 15, affixed to the cap, and is operated through the medium of a bell-crank lever 16 and rods leading to the foot-board. This cam and cam-lever are intended to impart spiral or screw movement to the valve-stem. Hence the valve and gate 17 when given a partial rotation by axial movement' of the valve-stem move longitudinally within the shell 3. In this manner the valve is opened simultaneously with the opening of the dischargeaperture 7.

There are to be three diEerent positions in the spray-viz, light, medium, and full-and the obliquity of the cam corresponds to such variations in the thickness'of the sheet of water.

The gate 17 is a circular plate adapted to fit the interior of the shell 3 closely and yet allow of rotation. The edge of the said gate fits closely against the edge of the flange 19 has been operated to move the gate and open the discharge-aperture further rotation of the gate is permissible, the cam-lever wiping upon a level portion of the cam.

which now exists between the edge 18 of the gate and the side 19 of the shell 3, thus closing the same and diminishing the length of the aperture, according to the amount of roi tation. This operation serves to cut oif or reduce the outward lateral throw of the spray when in proximity to a passing object. Th n-s without any difficulty the driver from the; foot-board can control the spray in any way whatever-that is, a full or partial gate can bemaintained,and these several adjustments l combined with a light, medium, or full spray. I

In other words, the thickness of the sheet of water can be varied, while at the same time the length of the aperture through which the water passes can be diminished or increased 'or remain constant, if so desired.

The operation is as follows: Rocking or upward lifting movement of the cam-lever 14,

which wipes upon its cam, serves to axially rotateand at the same time imparts endwise l travelto the valve-stem. Such action results in lifting the valve from its seat and at the same time slightly opens the discharge-aperture 7,

hitherto closed, when a thin sheet of water under the pressure from the tank is impelled outwardly. If this is sufficient for the pnr- On the pose, the lever is locked in position.

contrary, if agreater body of water is required I further axial movement of thelever upon the cam serves to increase the discharge-opening, while if the length of the discharge-aperture is to be reduced still further rotation is e f- This further rotation advances the lip across the aperture fected. This advances the lip 20 across the discharge-orifice and closes the same in part along its upper portion, thereby cutting off the extreme outer lateral throw of the spray,

and consequently the area or expanse of surface to be wet.

What we claim is- 1. The combination, in a sprinkling-cart, of a reservoir, a cylindrical sprinkling-shell suitably communicating therewith and provided with a circumferential discharge-opening, an oscillating valve within said shell to control the water-supply, an interior revoluble gate to regulatethe length and width of said circumferential discharge opening, and means for simultaneously operating said valve and gate, substantially as set forth.

2. A sprinkling or spraying nozzle having a semi-circumferential discharge-aperture, an axiallymovable valve-stem with endwise movement, an internal valve thereupon to adnait passage of liquid through the nozzle, and a revoluble gate likewise upon said valve-stem to regulate the width and length of the discharge-opening,substantially as described.

3. The combination, in a sprinkling-cart, of a reservoir, cylindrical sprinkler-head's suitably communicating therewith a'nd provided with circumferential discharge openings, spring-pressed endwise-movable rotary valvestems within said shells, each of said valvestems having mounted thereon a valve to control the water-supply to said head,'anda gate to regulate the length and width of said circu m'feren'tial discharge-openings, and thereby control the length of throw and the water-discharge of said sprinkler-head, and means for operating said valve s'tem to ac'tu ateisaid valve and gate, substantially as described.

In testimony whereof weat'fi'x our signatures in presence of two witnesses.
