    Abstract: 8743. Schaefer, W., and Lutz, H. May 11. Firebars and grates; fuel surfaces; smoke-consuming; mechanical stoking.-The fuel is received on a central, flat, imperforate surface P with troughs on each side, the outer ends, or, if desired, the whole, of the troughs being of grate form. The surface is preferably formed of a number of transverse bars, each in two parts, with ribs resting on bearers b. The ends of the bars leave air spaces between them and the side walls of the furnace, and above them are plates d which direct the air to the upper part of the fire. As shown in Fig. 3, the bars are in two parts, overlapping at the centre, and resting on a central rocking support q by means of which one part of each bar, which merely rests on its support b without embracing it, may be shaken transversely to clear the grate of ashes. The movable parts of adjacent bars are arranged on opposite sides of the furnace. The flat portion P of the fuel surface may be situated to one side of the furnace, there being only one trough on the other side. Coal is fed from a hopper R by a box k, open at top and bottom, and capable of being moved to and fro on the continuation P of the surface P by means of a handle O. At the front and back of the box are flaps l and m which open in the direction of the arrows, the former being made of plough shape. The box being filled, it is pushed forward under the adjustable shutter n into the furnace, and displaces the fuel therein, to right and left. On withdrawing the box, the flap l lifts, and the coal is left behind, while fresh coal enters from the back.

    Abstract: The large wheel (11) with tubeless tyre (12) is secured on a rig (10) mounted on the bottom of a vertical arm (9). This is raised by a first ram (4) and tilted by a second ram (6). The rams are operated to press the tyre against tools to loosen it from the wheel rim. The wheel is then tilted to allow eccentrically mounted tools to remove the tyre from the rim, while the wheel is prevented from rotating by a strut braced on the ground. No rotating motor is required, thus simplifying the equipment. The tyre support plate can be replaced by three radially sprung segments for w ght saving.
