The distribution of the fuel over the grate is effected by ablower (F) connected to the rim of the coking chamber (D)and immediately above the level of the grate at that point. Itconsists of a blowing ring, surrounding the opening of thecoking chamber and having a number of openings, directed up-ward and forward, to which blasts of steam are supplied forthe purpose of blov/ing the partially coked fuel forward on thegrate, and to aid in the combustion of the mass of fuel in thechamber (D). This ring is supplied by exhaust steam fromthe engine (G) which operates the charging PLAN OF THE NEW RAIT LOCOMOTIVE STOKER. This design is prominently characterized by a high degree ofsimplicity, and infringes to a minimum on the space availablefor the movement of the engine crew. In the design of thisstoker the recognized requirements for such a device have beenborne prominently in mind by the inventor, i. e., compactness,detachabality, in case of failure; freedom from complication,substantial construction, accessibility to repairs, and even dis-tribution of fuel. The claim is also advanced that this inven-tion allows of manipulation without the fireman leaving hisseat, and that by very little hand labor imposed upon him whilethe locomotive is in motion he is better enabled to assist in thelookout, and thus reduce danger in the operation of the train. In brief, the device consists of a charging mechanism (A)which delivers fuel from the tender (B) to a flexible conveyingtube (C) lying between the engine and tender, an expand
