Abstract: 413,707. Gas cooking-stoves; burners. MOORE CORPORATION, Joliet, Illinois, U.S.A. Jan. 20, 1933, No. 1955. Convention date, Jan. 20, 1932. [Classes 75 (i) and 126.] A gas cooking-stove has a body comprising a flat back wall 21, a flat front wall 23, and curved side portions 22 joining the edges of the two. In the stove shown, the central portion comprises a superposed hot-plate portion, the front of which is closed by a valve panel 26, an oven closed by a door 25, and a griller closed by a door 24. The side portions are separated from the centre portion by partitions, and are closed by curved doors 29, the hinges of which are formed by curled edges 36 in which engage pivot pins 37, 39 (Fig. 4) extending inwardly from the top and bottom walls of the stove. Shelves are provided in the left hand compartment, and the valves and thermostatic regulator for the oven and griller burners are housed in the right-hand compartment. The fall-down oven door, Fig 8, comprises a rectangular skeleton frame to which are secured front and rear plates having telescoping flanged edges, the front plate being secured by brackets 59 welded to its inner face and lying in recesses formed by offset parts 56 of the frame, to which they are bolted. The rear plate is secured by screws 67. Stop and balance devices of usual construction are provided. A table top 28 which covers the entire top of the stove is pivoted by brackets 83, Fig. 10, at the rear edge of the stove and is raised under the control of a balance spring 95 to the vertical position when the hot-plate is to be used, where it is supported by a hooked brace rod 98 at each side. The tops of the curved side compartments of the stove are level with the surface of the hot-plate, to form tables when the stove is in use. The front portion 121, Fig. 13, of the hot-plate is detachable to give access to the burner valves and mixing-chambers. Fig. 13b shows the underside of the end of one of the burner mixing- chambers, the air inlet apertures 171, 172 associated with high and low duty parts of the burner being provided with pivoted quadrantform covers 173 provided with extensions 176 for engagement from above by a screwdriver for adjustment purposes. The Specification as open to inspection under Sect. 91 comprises also the means shown in Fig. 15 (Cancelled) for supporting a pan 141 at adjustable height in the boiler compartment. The front opening of this compartment is closed by a plate 132 attached to a frame, formed by side rails 133 and a rear cross member 134, which slides into and out of the compartment. Rock-bars 135 mounted in the frame carry at their front and rear ends arms 137 which are pivoted at their upper ends to cross members 139 provided with rollers 146 on which the pan 141 rests. Links 142 are pivoted to the arms 137 on one of the rock-bars, and carry pins 140 passing through slots in the cross members 139 and into notches in flanges of the pan. The parts are so dimensioned that the pins 140 move substantially vertically, and so confine the boiler pan to the same movement. The linkage is operated by the door handle 159, through an arm 153 and a slotted arm 147 on one of the rock bars 135. This subject-matter does not appear in the Specification as accepted.
