Abstract

18,979. Parker, J. Sept. 10. Cooking-ranges; dampers.-Flues controlled by dampers are formed in connexion with the boilers of cooking-ranges and domestic fire-places so that the gases may pass through ducts in the boiler before passing to the oven, but, when they are passed direct to the oven, the boiler is still adequately heated. Fig. 1 shows a saddle or like shaped boiler with the grate continued under the boiler so that the fire burns within its arch. A water space d is formed at the back, and there are also provided a vertical duct e and side flues g which lead the gases over and around the oven or ovens and beneath the top plate h ; the gases may be utilized for other beating purposes. The side flues g may be formed by the top of the boiler, which is higher at the back, and the hot plate. The side flues are opened or closed by a damper i, Fig. 5, actuated by a straight rod n or a lever l and a handle. The ordinary side flues over the oven may be opened and closed by a swivelling damper y, or louver dampers such as are described in Specification No. 28,713, A.D. 1903, may be used in the uptake oven flue f. Fig. 7 shows in side view a rectangular boiler p with flues e, g, as in Fig. 1. Fig. 9 shows a saddle boiler with its side flues g arranged diagonally, dispensing with a vertical flue. Fig. 13 shows a rectangular boiler with arch-shaped recesses q forming side flues and with an end water space formed as shown. Curved side flues g through the boiler may be used with a rectangular boiler having a water space d as shown in Fig. 15. Fig. 18 shows a boiler having an arched passage r forming side flues. The side flues may also be formed of brickwork or metalwork at the sides of the boiler as at s, Fig. 21. In the form shown in Fig. 22, the gases pass through a vertical flue e into side flues z formed in an overhanging part. An ash-pan u and a hot air space v may be disposed below the grate, and an opening at the back of the boiler with a damper w enables the ashes to be pushed into the pan as described in Specification No. 24,006, A.D. 1906.
