Patented May 1936V UNITED STATES PATENT OFFICE CONTAINER DOOR AND CHARGING HOLE COVER Application March 22, 1934, Serial No. 716,801

2 Claims.

The principal object of the present invention is to provide for tightly seating the cover of a charging hole in response to the lateral motion of a door used for a container, the outlet of which is opposite the charging hole, so that, when the door is moved laterally, the cover is lifted and carried out of the way with the door, and, when the door is returned to its closed position, the cover is carried with it and tightly seated upon its frame.

Other objects of the present invention will appear from the following description at the end of which the invention will be claimed.

The invention comprises the improvements to be presently described and finally claimed. In the following description, reference will be made to the accompanying drawing forming part hereof and in which:

Fig. 1 is a sectional view illustrating mechanism embodying features of the invention; and

Fig. 2 is a similar View taken on the line 2 2 of Figure 1 with parts omitted for the sake of clearness.

In the drawing, I indicates a container, open at the bottom and adapted to receive material to be incinerated. It is supported as by I-beams shown in Figure l at the right and at the left. 2 indicates a door for opening and closing the opening in the bottom of the container. Aligned with the opening in the container and spaced therefrom is the entrance opening of an incinerating chamber 3. Door 2 is mounted upon wheels 4 adapted to ride on rails 6 and to be moved thereon by any suitable means, and there is shown, for that purpose, i. e., moving the door on the rails, a rod I connected with a flange or bracket 8 at the leading, right hand in the drawing, Fig. l, edge of the door 2. 9 is a cover for the incinerating chamber.

Interposed between the door 2 and the cover 9, and connected with each, are pivotal links operated by a bell crank to lift the cover 9. As shown there are links I0 and II forming toggle joints. The knuckles of the toggle joints are connected by a link I2 and shafts. The link I2 is connected with bell-crank levers I3, pivoted to the door 2 by shaft a and having trailing rollers I 4 which ride upon inclined portions I5 of the rails and also upon the rails.

The charging hole is provided with a frame I 6 having an inclined wall II, which, however, ter-- minates short of the leading, right hand, in Fig. l, edge of the door. The purpose of the inclined wall is to guide material from container I to the incinerator 3.

At the following, left in the drawing, as shown in Fig. 1, edge of the cover, there is an inclined wall section I8 which, when the cover is in the open position in Fig. 1, co-operates with the inclined wall II in guiding material. The cover 9, with the exception of the leading edge, righthand in the drawing, Fig. 1, is inclined to t the wall II and provide a tight joint. At the leading edge, right-hand in the drawing, Fig. l, the cover overlaps the frame I6 as indicated in the drawing.

A mode of operation may be described as follows: When the door is shifted laterally toward the right on the rails, for example by means of the rod "I, each of the trailing arms I3 of the bellcrank levers rides on inclines I5, and is thereby turned slightly in clockwise direction. This motion of the bell-cranks shifts the link I2 towardY the left in the drawing, and the link shifts the knuckles of the links, forming toggle joints in the same direction. Thus the cover 9 is lifted from its seat in the frame I6 and is carried in suspension from the door 2 toward the right. Thus the door and the cover are moved into position for permitting the contents of the container to fall into incinerator 3. During this operation the inclined wall II of the door frame and the inclined wall section I3 on the following edge of the door co-operate to guide the material from the container into the incinerator. It may be remarked that as shown, as the door moves toward the right, and as the cover is lifted, the leading right-hand, Fig. l, edge of the cover is unobstructed by any part of the frame, so that the cover may travel with the door as it is lifted. The trailing levers I3, when they ride on the straight portions of the rails, serve to hold the cover in suspension from the door.

It will be obvious to those skilled in the art to which the invention relates that modications may be made in details of construction and arrangement in matters of mere form without departing from the spirit of the invention which is not limited in respect to such matters or otherwise than as the prior art and the appended claims may require.

I claim:

1. The combination with an incinerator having an opening in its top and a container mounted thereon and having an open bottom communicating said opening, of a laterally slidable door closing said open bottom and a cover closing said opening, said door and cover being spaced apart and connected by a plurality of toggle joints, means for moving the door laterally to uncover said open bottom and means for actuating the toggle joints to lift said cover on the movement of said door, the cover moving laterally with the door.'

2. The combination with an incinerator having an opening in its top and a container mounted above the same and having an open bottom communicating with said opening, of a laterally slidable door closing said open bottom and a cover closing said opening, said door and cover being spaced apart and connected by pivotal links, means for moving the door laterally to uncover said open bottom and a bell crank and inclined rail coacting therewith for actuating the links to lift said cover on the movement of said door, the cover moving laterally with the door.
