Abstract
417,255. Drag scrapers. TAYLOR, H. J., Trolorne, Uxbridge Road, Hatch End, Middlesex. March 21, 1933, No. 8510. [Class 78 (iv).] A drag scraper for gathering coal from a storage heap comprises a box-like frame 1 having a scraper blade 12 projecting below the bottom of the frame and a rudder or rudders 2, 8 which are freely pivoted as at 3, 9, at the end or ends of the frame and extend below the frame so as to penetrate the material and prevent lateral motion of the frame. The haulage cable is attached to the free ends of the rudders. As shown the blade 12 is pivoted at 11 and may be swung over from the stop 13 to the stop 13a for operating the scraper in the reverse direction. Plates 14 prevent overflow of the coal. The Provisional Specification describes also a modification in which, to permit working in either direction, the frame is provided with a hinged scraper blade at each end, the blade at the leading end being raised and secured in an inoperative position.
