811,516. Oil stoves. POON, W. K. March 26, 1957 [March 26, 1956], No. 9344/56. Class 126 An oil stove comprises a burner 1, Fig. 2, a heating plate 3 and an outer casing 2 on one side of which a fuel tank 11, Fig. 3, is fitted. The burner 1 consists of an annular pre-heating pan 4 forming part of a carrier 5 in which an opening is filled by a perforated cup 6 to allow combustion air to pass upwardly through the burner. Alcohol is supplied to the pan 4 via a groove 8 in the plate and a trough 7 accessible through an opening 7a in the casing. An annular evaporating pan 9 receiving fuel from the tank by a pipe 10 surmounts the pan 4 and is, in turn, surmounted by an inner perforated evaporating cylinder 12 with a perforated end wall 13, enclosed within an outer open-ended perforated cylinder 16 to leave an annular space 17 between them. The cylinders 12, 16 are enclosed within a non-perforated cylindrical cover 18. The fuel tank has a filling opening and cap and a valve 20 controlled by a knob 21 having a pointer movable relatively to an indicating plate 22 on the tank. A safety valve 23 and valve 20 together control fuel passages in a valve body 25 fitted with a leg 26. In a modification, the fuel may be controlled by a needle valve 30, Fig. 4, carried by a float 27 in a chamber 28 supplied by gravity with fuel from the tank by a port 29 covered with a filter 31. The chamber has an air inlet controlled by a screw 32, and a fuel drainage plug 33.
