<p>Mixing device, for adding a liq. manure to a watering hose for horticultural purposes, consists of a tubular insert with a central choke; capillary tubes pass from eahc side of the choke to a can contg. the manure. The insert is fixed in the hose by the connectors and has a choke at its mid-point made by heat deformation. Capillary tubes are wedged into the insert, one on each side of the choke. Their other ends are wedged into the container, for holding the liq. manure, at the points. When water is flowing through the hose, it is slowed down when it reaches the choke so the pressure increases and causes a proportion to flow through one capillary tube into the reservoir. Some of the manure is pushed into the other capillary tube which takes it to the downstream side of the choke; the water leaving the insert is thus enriched with a certain quantity of manure.</p> |
