DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings in detail there is illustrated a preferred form ofa musical lawn sprinkler constructed in accordance with the principles of the present invention and designated generally in its entirety by the reference numeral 10 and which is comprised of a base 11 having a hollow housing 12 mounted thereon containing a rotary impeller 13 inwardly thereof and drivingly connected at its axis to a rod 14 projecting vertically upwardly therefrom through a surrounding tubular sleeve 15, the sleeve 15 having a pair of spring wired tines 16 supported at the top end thereof and projecting into the path of metal wire spokes of wagon wheel shaped member 18 which is fixed to shaft 14 for rotation therewith, the peripheral edges of member 18 connected about the circular base of hollow cone shaped head member 19 affixed at its apex 20 to the top end of shaft 14 with wing nut 21 retaining the same thereon.

The base 11 consists of'a horizontal base member 31 having a plurality of inclined legs 32 projecting downwardly and outwardly therefrom adapted to support the sprinkler 10 on the ground 33. The base may be manufactured out of metal, hard rubber, plastic, or any other suitable satisfactory material providing an aesthetically pleasing and refined appearance.

Mounted centrally on the top surface of the base member 31 is the hollow housing 12 which is preferably of a cylindrical configuration having cylindrical side walls 35 interconnecting top surface 36 and bottom surface 37 and defining interiorly thereof a compartment 38. A water intake valve 39 is affixed to a portion of side wall 35 in communication with interior compartment 38 and is adapted to have attached to the projecting free end thereof a conventional garden hose 40 for directing water into compartment 38. The top surface 36 of compartment 38 is defined by a baffle plate the shaft is rotatably driven upon rotation of the impeller. In the preferred embodiment the shaft has a diameter of about five-eighths of an inch.

The tubular sleeve 15 is disposed concentric with shaft 14 completely surrounding the same and extending longitudinally therealong with its bottom end affixed to housing 12 and terminating in a top end 55, the

sleeve defining interior Water passageway 56 therealong. The sleeve is preferably manufactured of plastic piping having a diameter of about one and one-quarter inches.

Affixed to the top end 55 of sleeving 15 is a stationarily mounted water outlet disc shaped plate 60 which is of a flat configuration and provided with a plurality of apertures 61 extending vertically therethrough and in communication with passageway 56, the plate completely covering the top end 55 of the sleeving. An opening 62 is provided centrally of plate 60 and extends vertically therethrough for receiving shaft 14 therethrough.

Thespring metal tines are of a rectangular configuration projecting upwardly from a clamp 65 affixed to the top end portion of sleeving 15 and extending circumferally thereabout, each of the tines being disposed radially relative to the sleeving. It is to be understood that the clamp 65 may be formed integrally with sleeving 15 if so desired.

The member 18 is of a wagon-wheel spoke configuration having concentric inner and outer ring members 70 and 71 interconnected by radially extending metal wires 17 which arepreferably manufactured of stainless steel having a diameter of about 0.018 inches. The inner ring 70 is provided with a concentric center opening 73 therein which is affixed to shaft 14 for driving rotation therewith upon rotation of the shaft, and is positioned on the shaft in a manner such that the top edges of tines 16 project a slight distance through the member between the spokes 17 such that upon rotation of the member 18 the spokes will encounter the tines to emit a high pitched melody.

The member 18 is affixed to the shaft 14 by the outer ring 71 being affixed to the circular bottom edge of hollow conical member 19 terminating in an apex member 21 in the form of a ring shaped member adapted to fit onto the top edge 52 of shaft 14, the top end 52 having a threaded boss 53 projecting axially therefrom and onto which is adapted to be received wing nut 21 for securing the member 18 and conical member 19 in position thereon.

In operation, water flows throughs garden hose 40 and intake valve 39 into housing compartment 38 where it impinges on wings 46 to effect the rotation of impeller 13, the water being discharged through triangular cut-out 42 of baffle plate 41 from whence it passes through passageway 56 to be discharged through apertures 61 ofoutletplate 60. As seen in FIG. 1, the water then impinges on the interior surface of conical head portion 19 from whence it is deflected downwardly into a general conical shaped spray about the sprinkler 10.

The rotation of impeller'13 effects simultaneous rotation of shaft 14 which, in turn, drives conical member 19 affixed thereto which supports spoked member 18,

the rotation of the spoked member effecting successive engagement of the metal wire spokes 17 with spring metal tines 16 to produce a high pitched melody during the operation of the sprinkler.

Should it be desired to spray a larger area with the sprinkler and not produce music, then, as seen in FIG. 5, conical member 19 and attached plate 18 are inverted on shaft 14 with plate 18 then being affixed to top end 52 of shaft 14 and with apex ring 20 resting adjacent outlet plate 60. In this manner water discharged through outlet plate apertures 61 impinges on the inverted conical surface 19 from whence it is deflected outwardly into a larger spray area than before.

It is to be understood that the form of this invention herewith shownand described is to be taken as a preferred example of the same, and that this invention is not to be limited to the exact arrangement of parts shown in the accompanying drawings or described in this specification as various changes in the details of construction as to shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention, the scope of the novel concepts thereof, or the scope of the sub-joined claims.
