To'all whom 'it may concern:

Be it known that i, THOMAS @inimmaona, a citizen ot' the United States. residing aty Salem. in the county of Columbiana and State ot Ohio, have invented certain new and useful 1lnprm'einents in Lawn-Spray Nozzles; and I doherehy declare the following to be a full. clear, and exactI description of the invention, such kas will enable others .skilled in the art to which it appertains to malte and use the same.

My invention relates tonozzles for spreading water, has especial reference to spray nozzles used for spraying water u on lawns and the like', has for its object a cheap, etlicientl and durable structure for the purpose, and consists in certain improvements in construction.- which will oe fully disclosed in the 'following speciicatiou and claims.

in the accompanying drawings, which torni part of this specification:HFigure l represents a side elevation of a spray nozzle Fig. 2 a Vertical longitudinal section showing the lateral discharge passages open or uncovered, and l ig. t. a like View showing said passages closed.

Reference being had to the drawings and the designating characters thereon, the numeral l indicates the body of the nozzle, 2 a stein to he inserted in the ground to sup- 1port the nozzle while inuse. 5S the receiving,r end provided with au internal screwthread Lifor attachment to a hose., not shown. 5 a chamber at the discharge end of the nozzle provided with a cylindrical Nall (i in which are lateral discharge passages 7. of which there may he any desired nuinoer, and in the end 5% is a discharge opening 5), which is controlled h r a conical valve l0 adjastahl)v supported on a stein ll which extends through the chamber 5 and is secured to the-hotlyY l at l2.

hu'roiuuliug the wall ti, is au annular sleeve 'lil provided with an interal -screw thread ll which engages a threaded portion l?) on the body of the nozzle and on which the .sleeve is vertically adjustable to control lthe discharge of watt-r through the lateral passages T. hy means4 o'l" a horizontal and inwardhY extending` annular valve or lip lt whose width is equal to the diameter of the passages T.- and ou the upper end otx the sleeve adjacent to the. valve lo is an out.- wardlj` tiered or hert-led annular surface 1T, against which the water issuing lroxu the passages T impide-es and is disintegrated or jected in substantially the saine direction iis the water discharged troni the passages 7.

The roluiue of th'e dischargeof Water may he regulated from the maximum capacit-y of the. nozzle to a spray of an;y desired ineness hy the adjustment of the valves 1l) and 16, and hy the use of either valve singly or hy using the two in conjunction with each other.

lt'is obvious that changes may be made in the details oi' construction without departing from the spirit4 of my invention, For example, the passages T, may he drilled atan angle on one. side of the center of the chainher 5. which will cause the water to strike the ir. line 1T at an angle and impart a cir-v cular motion to the water as it is discharged.

llaving thus fully described niyinventlon, what l claim is: j

l. A. spray nozzle having an openin in the discharge end thereof, a valve adjust,-l ahle at a right. angle to the plane of Said opening, lateral discharge passages adjacent; to said end, au outwardly flaring Vannularv surface adjacent to said passages, and. means tor controllingl the discharge of water through the late al passages. l

2. .t spray nozzle having an openingin 'its discharge end, a coniealvalve in said opening and adjustable aty a right angle to the plane of the opening, lateral )assage's adjacent to said end, and an a instable ysleeve having an outwardly flaring annular surface adjacent. to said passages.

3. .spray -nozzle having an opening in the discharge end thereof, a conical valve adjustable in said opening', lateral passages adjacent to said end. an adjustable sleeve provided with an annular valve to control the discharge of water through said passages, and having an outwardly flaring annular surface at its cud and opposite said passages. i
