The sides, it will he noted, are entirely free from outsideside stakes or other projections beyond the plane of the sidesheets. The car present- a smooth, straight -urface through-out the depth of the body at all points to engage the block-. The Lewis Truck is 3,850 cu. ft. level full or 4,450 cu. ft. with a 30 degreeheap. This latter figure, with coal at 54 lb. per cu. ft., isequivalent to approximately 240,000 lb. The cars are sten-cilled 218,000 lb. capacity, but, adding a 10 per cent over-load, brings the capacity to approximately 240,000 lb., the ing and clamps in car dumpers, thus, avoiding concentratedstresses on side stakes, top angles and other projections whilethe car is being dumped. This construction also admits ofusing practically all of the clearance width of the road forthe inside or available loading width of the car and pro- 2^3Si£prin^~ f-a- i Mild Steel
