Abstract: 10,177. Kitson, A., and Noblett, A. April 26. [Cognate Applications, 11,122/11 and 15,463/11.] Vaporizing-apparatus. - Vapour-burning apparatus for lighting and heating is provided with means adapted automatically to supply the vaporizer with oil only during the desired lighting period, and to supply automatically the requisite quantity of spirit for the preheater and to ignite the spirit so supplied at the desired time for lighting the apparatus, with or without a thermostatic device for preventing premature admission of oil to the vaporizer. The large oil reservoir 1, Fig. 1, communicates with the small reservoir 2 by a pipe 3 containing a valve 4, which is set so that the time occupied by the flow into the small reservoir of the quantity of fuel used in the desired lighting period is the time during which the apparatus is extinguished. The reservoir 2 communicates with the vaporizer 38 by a pipe 8 provided with a valve 5, which remains closed during the filling of the reservoir. The valve stem 9 is connected to a lever 10 carrying a vessel 11 partly filled with liquid, so that on the descent of the valve 5 it is kept down by the increased turning- moment of the liquid caused by its displacement, until the pressure on the upper surface of the valve is reduced sufficiently to allow the weight 12 to raise it into its closed position. The weight 12 is adjustably mounted on the lever 10 in order that the times of operation of the valve 5 may be varied. The lever 10 also closes a valve 13 in the supply pipe 3 when the valve 5 is open. The spirit reservoir 16, Fig. 1, which supplies fluid to the preheater 14 through the pipe 20, is provided with a measuring chamber 17, which is filled when the valve stem 15 is in its upper position and emptied when the stem is lowered. The valve stem 15 carries two valves 18, 19 and is connected to the lever 10. A wick 22 leads from the preheater 14 to a continuously-burning lamp 21, but this ignition device may be replaced by an electric device hereinafter described. One terminal of the primary coil of the induction coil 24 is connected to a terminal of the battery 23, and the other terminal is connected to one terminal 30 of a pair 30, 31, the other of which is connected to the remaining terminal of the battery. The terminals of the secondary coil of the induction coil 24 are connected to the lamp casing 29 and to a wire 28 placed opposite a sparking-terminal 33 on the preheater, this terminal and the lamp casing being in electrical connexion, so that when the terminals 30, 31 are connected by the lever 10, sparks pass to ignite the spirit. In a modification, an ordinary oil reservoir and a spirit reservoir are connected by pipes to the vaporizer and preheater, respectively, these pipes being provided with spring - controlled valves 40, 41, Fig. 4, which are operated by clock-work. A dial 42, adapted to rotate once in 24 hours, is provided with a cam 43 having end pieces which are adapted to act on one end of a pivoted lever 47, the other end of which engages the stem 50 of the oil valve 40. The dial may be marked with numbers indicating hours, and the cam 43 may be made in two parts adapted to overlap each other and to be adjusted on the dial. A pin 54 is secured to the cam so that it acts on the end of a pivoted lever 55 which is secured to the stem of the valve 41. The spirit reservoir is provided with an horizontal partition containing a small hole through which the spirit passes very slowly, so that the lower chamber acts as a measuring-chamber. The valves 40, 41 may be opened simultaneously when a thermostatic device is employed for preventing premature admission of fuel to the reservoir. The clock-work may be secured to the chimney 60 by an adjustable band 61. The valve 41 might control the supply of illuminating gas to a Bunsen burner for preheating the vaporizer. In a modification, the clockwork mechanism comprises a member adapted to move at a regular speed and two other members each of which is connected to the valve for controlling the supply of oil, and of which one is caused by the first member to open the valve at a predetermined time, and the other to close the valve, while the connexion between the two is such that the operation of each will restore the other to its initial position. In another modification, the clock-work mechanism comprises two members each of which is adapted to move at a regular speed, and one is adapted to engage with the oil valve and open it, and the other is adapted to close the valve. In both modifications the supply of spirit for the preheater is controlled by a cam.
