[Class 126] In an oven, a slidable drawer has.a front closure wall 15, a rear wall 20, and mechanism concealed in these two walls for moving a food support or pan 76 vertically within the drawer. Lugs 75 at the front and rear of the pan are slidable in vertical slots 74 in the front and rear walls, and rest on a pair of pivoted arms 63, 64 accommodated in the front wall, and on a similar pair of arms in the rear wall. The arms 63, 64 have interengaging toothed sectors 69, 70 so that they move together. Rotation of the handle 50 on the closure wall 15 rotates the shaft 59 through the pinion 51 and toothed sector 58. The shaft actuates the arms 63, 64 through the arm 61 and a pair of links 62, one link on each side of the arm 63. Projections 72 on the links 62 prevent the teeth of the sectors 69, 70 from disengaging. The similar pair of arms in the rear wall are similarly actuated by the shaft 59. A spring 56 engages the pinion 51 to hold it in the adjusted position. The drawer itself is supported at the front by rollers 37 attached to the body of the oven, and at the rear by rollers 28 attached to the drawer. The flanges 23 resting on the rollers 37 also engage below rollers 36 which prevent the drawer from tipping when in the forward position. Projections 42 limit the forward movement of the drawer.

Abstract: 209,926. Peters & Co., Ltd., G. D., and Broekman, A. L. Dec. 20, 1922. Controlling propelling and steering mechanism by vehicle couplings; adjusting forecarriages for steering; stopgear operated non-voluntarily. -A motor vehicle is adapted to be used also as a trailer by the provision at its front end of a draw bar or link whereby when the vehicle is coupled to a tractor, the power unit, the controlling mechanism and the steering gear are automatically thrown out of action. A self-contained motor forecarriage, Figs. 1 and 2, is provided with a draw-bar 49 secured to the shaft 48 mounted in bearings 46, the shaft 48 being so connected to the various controlling members that the forecarriage can be steered and driven only when the draw bar is in the lowered position shown in dotted lines. The steering hand-wheel 35 mounted on the forecarriage turns the latter relatively to the main frame by means of a shaft 34 carrying a worm engaging with a worm wheel 33, Fig. 6, keyed to the forecarriage pivot pin 22. The forecarriage can only be turned for steering purposes by the hand-wheel when the worm 33 and pin 22 are provented from turning by locking the sliding gear wheel 37 to the main frame. This is effected by raising the gear wheel 37 against the spring 40 until it engages teeth 38 carried by the frame members 29. The gear wheel is raised or lowered by a central pin 42 operated by a lever 44 connected by a link 51 to the shaft 48, Figs. 1 and 2, of the draw bar in such a way that the gear wheel 37 is only raised to enable the forecarriage to be steered when the draw bar is uncoupled and hanging down freely.
