Abstract

1,192,424. Watering plants. F. O. G. RIDDIFORD. 9 July, 1968 [10 July, 1967], No. 31720/67. Heading A1E. [Also in Divisions F2 and G1. A device for watering the seeds or plants in a tray 1 has a stainless steel ball valve 3 which is movable to permit water to flow out of bores 7 into the tray in response to movement of a permanent magnet 12 about axis 14, following movement of spring counterbalanced lever 21 about fulcrum 20, as a result of changes in weight of the contents of the tray. A screw 18 acts as an armature to produce snap action opening of the valve when a predetermined weight of water has evaporated from the tray. In various modifications (not shown) lever 21 can carry a movable magnetic shield co-operating with a stationary magnet and the counterbalancing spring 22 can be replaced by a counterweight.
