    Abstract: 1,149,287. Spray-producers. INTERNATIONAL PATENT RESEARCH CORP. 1 Sept., 1967 [15 Nov., 1966], No. 40175/67. Heading B2F. An oscillating sprinkler comprises a perforated curved pipe 2 mounted between a water supply housing C and a bearing housing (B), Fig. 1 (not shown), the pipe 2 being oscillated by a mechanism entirely enclosed within the housing C and including a turbine 90 driven by water issuing from an aperture 116 in a water-nose connection 118, a speed-reducing gear train (Fig. 3, not shown) including gears 92, 94, 96, and an eccentric (114), Figs. 3, 4 (not shown) acting on a cylindrical projection 50 forming a part of an element 44 attached to the pipe 2, the oscillation of the element 44 and hence the pipe 2 being guided by an arcuate projection 48 moving between pairs of pins 66, 68 formed on a wall of the housing C. The housing C comprises two sections 8, 10 fitting together with a watertight wedge-action joint formed between the peripheral wall 26 of the section 10 and a wall 16 of the section 8. A further wall portion 18 of the section 8 is formed with a lip 22 adapted to engage a ledge 28 on the wall 26 of the section 10. A tab 54 formed on the arcuate projection 48 is adapted to engage projections (70, 72, Fig. 3) in the event of displacement of the pipe 2 in order to prevent rotation of the pipe to a dead-centre position where oscillation will not occur, or to a position displaced 180‹ from the required position. A widened portion 84 on a fixed shaft 80 rotatably bearing the gears 92, 94, 96 decreases friction between gears 92, 94 and prevents binding. A projection 40 on the section 8 engages a tubular portion 38 on section 10 to assist assembly of the housing C.

    Abstract: 1,245,423. Lawn sprinkler. INTERNATIONAL PATENT RESEARCH CORP. 22 July, 1968 [8 Sept., 1967], No. 8578/71. Divided out of 1,245,422. Heading AID. [Also in Division B2] The subject matter of the specification is the same as that in Specification 1,245,422 but the claims are directed to a rotary deflector 152 which is capable of distributing water sprayed over a lawn area substantially uniformly both circumferentially and radially.
