3 Claims. (Cl. 299-61) The main objects of this invention are: spaced from the restricted throat providing a First, to provide a spray or sprinkling head chamber of substantial area between the throat well adapted for use on lawn sprinkling sysand the passage member which substantially retemswhich is eifective in' the discharge of water duces the turbulence and results in the water over asubstantial' area andat the same time being uniformly discharged from the head. 5' is not likely to become clogged, and one in which This passage member has a plurality of pethe. movable parts are effectively protected when ripheral spira'l grooves l6 which coact with a wall in retracted position. of the nozzle member in providing spiral passages Second,toprovideaspray head embodying these through which the water is delivered, thus setadvantages which is simple in its parts and the ting up a swirling or spiraling movement to the 10 parts easily. assembled and disassembled. water as it is discharged through the throat i2 Objects pertaining to details and economies of of the nozzle against the under side of the inthe invention will definitely appear from the deverted conical baffie i'i. scription to follow.

With the parts thus arranged they are simple and economical to produce and may be very easily assembled. There is little likelihood of their clogging in use, the nozzle member seating flush within the body member and the deflector or bafiie l1 seating flush within the nozzle tip.
I have illustrated and described my invention in an embodiment which I have found highly satisfactory. I have not attempted to illustrate or describe certain modifications or adaptations which I contemplate as it is believed that this disclosure will enable those skilled in the art to embody or adapt my improvements as may be des red.
Having thus described my invention what I claim as new and desire to secure by Letters Patent, is:
1. In a spray head, the combination of a tubular body member provided at the top thereof with an annular recess having an inwardly inclined bottom andwith an internal annular shoulder and having a longitudinal internal groove above said shoulder, an internally shouldered tubular nozzle member provided with an upwardly flared tip portion adapted to seat in said recess in said body member and having an annular upstanding peripheral flange, the edge of which is flush with the top of the body member when the nozzle is retracted, an inverted conical baiile member provided with a stem and adapted to seat within said nozzle tip and constituting a closure therefor when seated, a passage member disposed within said nozzle member against said shoulder therein and having a plurality of spirally disposed peripheral grooves coacting with the walls of the nozzle member to provide spiral passages, said passage member having a central conical opening receiving said stem, said stem being provided with a conical head seating in said opening when the baffle member is in elevated position, a tubular stem for said nozzle provided with a flange at its lower end coacting with said shoulder in said body member, and a coupling threaded into said nozzle member and into which said nozzle member stem is threaded, .said coupling being provided with a lug engaging said longitudinal groove in said body member.
2. In a spray head, the combination of a tubular body member provided at the top thereof with an annular recess having an inwardly inclined bottom and with an internal annular shoulder and having a longitudinal internal groove above said shoulder, a tubular nozzle member provided with an upwardly flared tip portion adapted to seat in said recess in said body member and having an annular upstanding peripheral flange, the edge of which is flush with the top of the body member when the nozzle is retracted, an inverted conical baiiie member provided with a stem and adapted to seat within said nozzle tip and constituting a closure therefor when seated,
tubular body member provided with a recess at the top having an inwardly inclined bottom, said body member having a longitudinal internal groove, of a tubular nozzle member provided with an upwardly flared tip portion adapted to seat in said recess in said body member, said nozzle member having an internal flange at the base of its conical tip portion providing a restricted throat and an internal shoulder substantially spaced from said flange, a passage member disposed within said nozzle member against said shoulder therein, said passage member havmg a central conical opening, an inverted conical baffle member provided with a stem, said stem having a conical head fitting said conical opening in said passage member when the baflle member is in its projected position whereby the baflle member is centrally supported with said stem centrally of said restricted throat when the baffle member is in projected position, and a coupling threaded into the inner end of said nozzle member and provided with a lug engaging said groove in said body member.
