SYSTEM FOR THE DESTRUCTION OF REFUSE.

Specification of Letters Patent.

Patented Dec. 19, 1905.

To a. whom it may concern.-

Be it known that we, GEORGE ATsoN, a resident of Pool, near Leeds, and HENRY WVIL- LIAM MAsoN, a resident of WVakefield, England, subjects of the King of Great Britain, have invented a new and Improved System for the Destruction of Refuse, of which the following is a full, clear, and exact description.

Our invention relates to systems for destroying street and house refuse and the like, and more particularly to those in which the material is delivered to furnaces in bulk. Its principal object is to provide an effective system for this purpose.

Reference is to be had to the accompanying drawings, which form a part of this specification, in which similar reference characters designate similar parts in all the views.

Figure 1 is a vertical longitudinal section through a building in which is installed one embodiment of our improved system. Fig. 2 is a transverse section through said building. Fig. 3 is a broken longitudinal section through one of the furnaces, it being taken on the line 3 3 of Fig. 5'. Fig. 4 is a similar View, but showing the movable elements in another position. Fig. 5 is asection on the line 5 5 of Fig. 4. Fig. 6 is an enlarged sectional detail taken on the line 6 6 of Fig. 7 and illustrating the latch mechanism of the hopper and more closely associated elements. Fig. 7 is an end elevation of this portion of the system. Fig. 8 is a horizontal section on the line 8 8 of Fig. 6. Fig. 9 is an enlarged section on the line 9 9 of Fig. 4. Figs. 10 and 11 are respectively side and end elevations of a carrier for the container. Fig. 12 is a central vertical section through said container. Fig. 13 is a similar view on the line 13 13 of Fig. 12, and Fig. 14 illustrates the container as supported upon a different form of crane from that included in Figs. 1 and 2.

1O designates a suitable building, in which are arranged batteries of furnaces 11, each of which is provided with a feed throat or opening 12. These furnaces may be of any type suitable for the cremation of refuse, and as they are preferably identical in character but one will be referred to in the following description. About the furnace-opening is a trough 13, adapted to contain a liquid, and thus furnish a water seal for a closure. This closure is provided by a door 14, having a flange 15 extending about it and of such length that it may project into the liquid in the trough. The door is mounted upon a car or carriage 16, which is conveniently in the form of an open frame supported upon pairs of wheels 17 17, operating over rails 18, situated at each side of the opening and extending beyond it upon the top of the furnace. Rising from the car are opposite brackets 19, between which is fulcrumed a lever or frame 20, pivotally connected to thedoor by converging suspension-rods 21. The Weight of the lever is preferably such that it nearly counterbalances the door, the excess of weight of the latter being carried by opposite rolls 22, rotatable in brackets 23 and running over tracks 24, parallel to the rails 18. In these tracks, adjacent to the furnace-throat, are depressions 25, serving to receive the rolls when the door is positioned with its flange over the trough, thus allowing it to be lowered into place. A stop 26, projecting above the car at the opposite end from the rail depressions, serves to limit the movement of the lever in this direction.

Rising from each side of the furnace-opening outside the rails are standards 27, each of which preferably comprises separated angleirons and which are connected at their tops by a cross-bar 27*. Guided by these standards are double brackets 28, projecting from a hopper or movable member 29, which may be balanced by weights 30, secured to the ends of chains 31, which pass over pulleys 32, rotatable at the top of the standards, and are connected below these pulleys to the hopper. Pivotally mounted 'upon each of the brackets is a guide 33, through which is movable a link 34, pivotally joined to the furnace at one extremity through a bracket and articulated at its outer end to a link 36, which is pivoted to the lever 20 at 37. Fulcrumed at 38 be.- tween the sections of each of the brackets 28 is a latch 39, having an arm 40 extending outwardly between upper and lower stop mem bers 41 and 42, respectively, fixed between the angle-irons of the standards.

The hopper is adapted to receive a container A for the refuse to be destroyed. This container comprises side walls 43, which are shown as diverging downwardly to facilitate free delivery. At the bottom of the walls, at

opposite sides, are hinged discharge-doors 44,

which have fixed near their outer edges blocks 46, which when in contact with the supporting-surface hold the doors closed. Projecting from each of the blocks beyond the walls of the container are arms 47, from which flexible members or chains 48 converge to attaching devices or hooks 49. Each of these books has a vertical opening to receive 7 a guide rod 50, supported near its ends by brackets 51, bolted to the containerwalls. Horizontal angle-bars 52 are shown as fastened to the container below the guide-rods. These bars when the container is introduced into the hopper may rest upon its sides to move said hopper downwardly and to support the container when these elements are in their lowest position. It also serves as a contact member forthe latch 39, thus constraining the hopper and container to travel together when the latter is raised. With the attaching devices cooperate separated hooks 53 53, depending from a carrier-frame 54, which may be suitably braced by inclined members 54. Secured at separate points upon the upper side of the carrier-frame are chains or flexible members 55,which extend upwardly over a pair of drums 56 56 of some suitable traveling crane or lifting means 56, movable upon rails,57,.extending between the walls of the building above the furnaces. The crane and carrier serve to transfer the containers to the furnace from a receiver or support, which is illustrated as consisting of a pit 58, situated below the fioor of the building and at one side of and between the batteries of furnaces. At the top of this pit and at opposite sides are carried tracks 59, over which operate wheels 60 of an open car 61, carrying a hopper 62. As shown, the pit is sufliciently large to receive two of the containers, and the hopper may be moved upon the track into vertical alinement with either of them or be positioned at one side to permit their withdrawal.

In using our system the refuse to be destroyed is brought by cars or the like to the pit or other point where the containers may be located. .The blocks of these. containers rest upon the bottom of the pit or other supporting-surface and maintain the dischargedoors closed. The hopper is now moved over the container which is to receive the charge, and the cars dump their contents into it until the desired amount has been introduced. The carrier being lowered by the crane until its hooks are below the container-hooks, these are brought into alinement and the carrier raised. The tension thus placed upon the dischargedoors through the connecting-chains holds them closed, and the container, with its contents, is thus lifted and moved over the feedopening of the furnace which is to be supplied, said opening being closed by its door. The

carrier is now allowed to fall between the standards until its side bars contact with the hopper, which is in its raised position, Figs. 4 and 5, and moves it before it. This causes the guides 33 to travel over the links 34, depressing the link 36 and the outer end of the lever, and consequently raising the door above the trough. At this time the lever contacts with the stop upon the carriage, and the continued movement of thelink 34 causes its companion link to approach a horizontal position, forcing the car outwardly and moving the door to one side of the feed-opening, Fig. 3, the rolls 22 moving over their tracks and supporting the lever and door at this end. After this has been accomplished the bottom of the hopper strikes the wall above the feedopening, and the weight of the container is supported upon said hopper. This relieves the tension upon the suspending members, and the doors are freed and allowed to swing to a vertical position, the contents falling into the furnace. As the hopper approaches its lowest position the arms of the latches contact with the stop 42, causing the hooks to move over the container-bars, thus locking said container and the hopper. The container having been em ptied of its contents, it is raised by the crane and carrier and by virtue of the engagement of the latches draws the hopper upwardly with it. This moves the links 34 and 36 toward their original position, resulting in a reversal of the movements previously described, the car being first caused to travel toward and over the furnace-opening and the door being finally lowered, with its flange extending below the surface of the water in the trough,-thus sealing the opening. When the hopper is in proximity to its initial position, its latches strike the stops 41, swinging the hooks outwardly and releasing the container, which is then drawn up sufficiently to clear the standards, when it may be carried by the crane to a point above the pit and lowered into it. The container is now ready to receive another charge. the containers need not be filled within the structure inclosing the furnaces, but may be mounted upon a suitable supporting-surface at some distant point, from which they may be transported in any convenient manner.

Instead of delivering the refuse to furnaces the containers may be employed for discharging their contents into other receivers, as vessels, and in this connection it might not be desirable to lower them upona support which will take their weight from the suspending members, so that the doors will open. In Fig. 14 of the drawings we have illustrated a jibcrane 63,'which has in addition to its main chain or cable 64 auxiliary cables 65, which have hooks 66engaging projections 67 from the containers. The upper extremities of these cables are fast to the crane, and they are of such length that when the container has been lowered to the desired extent they It will be obvious that support its weight and allow the doors to open.

Having thus described our invention, we claim as new and desireto secure by Letters Patent 1.
