Abstract: The present invention constitutes a rain sampling device adapted for independent operation at locations remote from the user which allows rainfall to be sampled in accordance with any schedule desired by the user. The rain sampling device includes a mechanism for directing wet precipitation into a chamber, a chamber for temporarily holding the precipitation during the process of collection, a valve mechanism for controllably releasing samples of said precipitation from said chamber, a means for distributing the samples released from the holding chamber into vessels adapted for permanently retaining these samples, and an electrical mechanism for regulating the operation of the device.

Abstract: A wheeled vehicle having a pair of forwardly projecting support arms carrying a rotary dethatching drum. A volute housing encloses the upper portion of said dethatching drum and opens for tangential forward discharge above the drum. The drum includes axially-spaced blades mounted in circumferentially staggered array upon a polygonally cross-sectioned shaft. The drum is supported upon a vertically adjustable gauge roller used to set the working depth of the dethatching blades. The dethatching drum is driven in rotation from the wheeled vehicle. L-shaped lever arms project from the wheeled vehicle toward the dethatching drum and support a foot pedal subassembly which permits the dethatching drum and its housing to be lifted upwardly by foot pressure applied by the operator.
