"Set of apparatus to simulate the action of rain on sidewalks, and measuring the intensity of rainfall, and establishing the standard of comparison for laboratory procedures."Model patent invention to the set formed by the apparatus I characterized by square with an area of 1 supported on a flexible material and provided with handles for transportation and fins of wood paTo support weights. All handles / fins enables the machine I to be vertical. The device h which works in dry and wet weather has a square base inverted pyramidal form.Works vertically supported in a quadripu00e9. Come into operation by the withdrawal of the rain cover and ceases to operate for the relocation of the same.The liquid collected in its interior is drained by the vertex. The volumes measured and calculated thus withdrawn, leaving the pattern and intensity of rainfall.
