No. 23237.—20th August, 1906.—JULIUS VON BERTOUCH, of Kapunda, South Australia, Australia, Licensed Surveyor. An improved machine for clearing land, roads, streets, or the like.

[NOTE.—This is an application under section 106 of the Act, the date given being the official date of the application in Australia.]

Extract from Specification.—My invention relates to an improved machine for clearing land, roads, streets, or the like, and refers more particularly to that class of machines in which the material to be cleared is gathered and conveyed up an endless elevator to a collecting-receptacle. The object of my invention is to provide an effective machine capable of being easily interchangeable for gathering loose stones or stumps, onions, potatoes, earth, and the like, cutting and collecting weeds, and sweeping roads or streets. I accomplish this by providing a machine having a gathering-device consisting of an adjustable stump-jumping rake or scoop of special construction adapted to engage obstacles at or near the surface of the ground, and a rotating double spindle having interchangeable gatherers, beaters, or brushes which carry or convey the material over the rake or scoop to an endless elevator of special construction which conveys the material to a tip receptacle connected to the framework at the rear of the machine.
