1,124,368. Spray-producers. SWIMQUIP Inc. 12 Sept., 1966 [22 Oct., 1965], No. 40633/ 66. Heading B2F. An intermittently rotated sprayer suitable for watering or cleaning comprises stationary body members 10, 15, 20, a hollow generally cylindrical plunger member 27 located between cylindrical surfaces 23a, 26 and biased downwardly between further members 23, 32 by a spring 34, and a pipe 12 adapted to supply water intermittently to the housing formed by the members 10, 15 whereby the plunger 27 is reciprocated. Radial webs 19 beneath the member 20 define a plurality of outlet ports 21 and a pin (43), Fig. 6 (not shown) on the plunger cooperates with cam surfaces (41), (42) on the member 23 so as to rotate the plunger on each reciprocation by an amount which registers an outlet orifice 39 in the side wall of the plunger with an adjacent part 21. Tongues on a flange 31 on the plunger cooperate with grooves in the member 32 in order to guide the plunger and prevent relative rotation between the plunger and the said member. The intermittent water supply is controlled by a motor-actuated valve V. The top of the plunger is closed apart from a vent hole 29 and slits in the lower portions of the plunger side walls prevent grit &c. from building up at the spring. The member 20 may be attached to the plunger or may be removed altogether.
