1 Claim. (01. 209-464) This invention relates generally to certain new Wall portion l8 rising from the outer edge of the and useful improvements in sand treating apledge and f g the p p y of the Wheel, as pa et s, but more particularly to an apparatus seen in Figures 2 and 3. These sand-receiving or deWatering and washing sand. shelves project a suitable distance at opposite One of its objects is the provision of a desides of the wheel and substantially centrally watering apparatus for sand and like materials thereof are provided with lugs or hinge brackets which is efficient, positive and reliable in operawhich epe d f t e ledge portion H of tion, and which is designed to operate at a maxieach shelf and are pivoted at 28 to a similar lug mum capacity with a minimum expenditure of or hinge member 2| applied to the wheel-rim,

Figure 3 is a Figure and thereby positively limiting the u cross-section taken substantially in the plane'of Ward displacement of the Shelf, particularly line 33, Figure 4, Figure 4 i fragmentary when loaded. As shown in Figures 3 and 5, this inside face view of one of the sand-receiving p s y be formed y cutting parallel slits shelves and associated parts. Figure 5 is a perin the shelf-ledge and t be e s tspective view of one of the sand-receiving shelves. ihg tongue downwardly t a angle 0 the led Figure 6 is a sectional end View of the apparatus.

By this construction, each sand-receiving shelf I6 is provided with ample wall structure to hold a maximum amount of sand and at the same time allow the water to drain off the moprising a revolvable wheel, and a two walled I sand-receiving shelf disposed transversely and exteriorly of the wheel-periphery and pivoted thereto to swing toward and from the same, both of said walls being disposed at one side of said pivot with one wall disposed radially of the wheel and the other in spaced circumferen-i tial relation thereto, and a stop member applied to said shelf in opposing relation to the wheelperiphery for engagementtherewith to limit the swinging of the shelf in a direction away from such periphery.
