Two sizes are provided, in order to adjustthe amount delivered without gauging or par-tially emptying a pocket. When 4 tons arewanted the large pocket is emptied. Bothpockets used together give six tons, and for8 tons the 4-ton pocket is used twice. Thesmall pockets are filled from a 60-ton storagepocket overhead. By using pneumatic, vertically movinggates between the storage and delivery pock-ets the latter may be emptied and filled inlets than one minute.

The coal supplied to tendersis always in two or four-ton lots, or in multiples thereof. With the fifty-ton storage pockets filled with coal, to eachone of which is attached a two and a four-ton measuring pocket,it is possible to dump the coal from both of these pockets, refillthem and again dump, supplying in all twelve tons to thetender, in less than one minute. We handle the coal fromsteel-hopper self-dumping cars to the locomotive tenders fromthese coaling trestles at a cost ranging between Vz
