Abstract: 26,826. Watson, G., and Mason, H. W. Dec. 9. Shoots; skips; slings.-Relates to apparatus for handling and storing town and like refuse prior to its being fed by a special charging-device to a refuse destructor of the kind described in Specification No. 26,002, A.D. 1897, [Abridgment Class Furnaces &c.], which is provided with a water-sealed lid of the kind described in Specification No. 13,736, A.D. 1901, [Abridgment Class Furnaces &c.]. The refuse is tipped from the carts into a hopper, as shown in Fig. 2, from which it falls into a container 2. When one container is full, the hopper, which is mounted upon a pin 5 and is provided with wheels 7 to run upon a track 6, is swung round by chain and sprocket-wheel gearing over another container. Instead of the hopper being turned, the containers may be supported upon a turntable and brought individually beneath the hopper. The containers are lifted out of the pit 3 and emptied into the destructor at once, or they may serve to store the refuse until it is to be transferred to the destructor. Each container consists of a box, as shown in Figs. 6 and 7, made of wood or iron and provided with a bottom 17 consisting of two hinged flaps. The flaps are kept closed, when the container is lifted by the hooks 19, which may slide upon bars 18 and which engage eyes 21 upon the sides of each flap by means of chains 20. The chains are of such a length that, when the hooks are in their uppermost position, the flaps are kept closed. The containers are lifted by means of an iron sling 25, Fig. 9, which is attached to a crane 28, Fig. 1, and are lowered down into a verticallysliding hopper 33 mounted by means of brackets 55, Fig. 13, in guides 48 fixed to the top of the furnace. The weight of the container causes a hopper, which is counterbalanced by a weight 54, Fig. 12, to fall until it rests upon the furnace over the charging-hole. During the lowering of the hopper, the water-sealed lid 32 is moved away from the charging-hole in the following manner :-The lid is mounted upon a tilting lever 35 by means of links 34. The lever 35 is pivoted at 37 to a carriage 38 which is adapted to run on rails 40. The lid is partly counterbalanced by a weight upon the lever, and, when being raised, is retained in a horizontal position by links 41, 42, 42<a>. The tilting of the lever 35 is effected by inverted rails 34 which engage with wheels 47 upon the lever, and the turned-up ends 45 of the rails allow the lever to be tilted when the lid is being raised or lowered. The lever and carriage upon which the lid is mounted are moved away from the charging-hole, as the hopper is lowered, by means of a lever 49 pivoted to the inclined stay 53, and links 56, 57, 53. The link 58 connects the tilting lever 35 to the lever 49, and the links 56, 57 connect the lever 49 to the bracket 55, Fig. 13, upon the hopper. When the weight of the hopper and container is taken by the furnace, the chains are lowered, and the flaps open to discharge the contents of the container into the furnace. As the container is raised, hooks 24 upon it engage with hooks 61, pivoted to brackets 55 upon the hopper, thus lifting the latter until it reaches its normal position, when the hooks 61 are automatically disengaged.
