ASH DISCHARGER Filed Sept. 1, 1933 2 Sheets-Sheet 2 Patented May 25, 1937 STATES PATENT OFFICE Application September 1, 1933, Serial No. 687,895 In Germany September 7, 1932 9 Claims.

This invention relates to a device intended especially for the removal of ashes and other materials, for instance coke, also slag, from furnaces and the like. The present improved device 5 pertains to that type of such devices in which the respective material is led by means of a vertical tube or branch into a receptacle or trough containing water, said tube or branch extending down to below the level of the water so that it 10 is tightly closed by the same. The object of the present improvements is to simplify the device and to render its manipulation particularly convenient. This is obtained by arranging and supporting the water-filled receptacle or trough in 15 such a manner that it is horizontally shiftable and at the same time tiltable on an axis extending through the center of gravity of the receptacle or trough, the arrangement being such that the trough while being moved in that twofold manner 20 does not in the least interfere with the abovementioned tube or branch through which the ashes or other material is introduced into the trough, or into the water of the same respectively. Owing to the tilting axle passing through the 25 center of gravity of the trough, as already stated,

the tilting can be easily effected by hand.

Ihe invention is illustrated diagrammatically and by way of example on the accompanying drawings on which Figure 1 is a longitudinal ver- 30 tical section through an ash-removing device designed according to this invention, Figure 2 is a transverse section through the same in the plane II II of Figure 1, and Figures 3, 4 and 5 show three positions of the trough while it is 35 being tilted.

On the drawings, i denotes a vertical branch through which the ashes or other material enters into the trough 2 which contains water to the level of the outlet 3 which serves as an overflow L aperture. The branch I terminates below the level of the water so that it is closed air-tight and gas-tight by the same. 4 are running rolls which are attached to the trough at the two sides of the same adjacent to an axis. extending through the center of gravity of the trough, and said rolls can run onhorizontal rails 5 forming, in the'example shown, the lower portions of a stationary frame 5. From this frame extend downwardly oscillable rods 1 which are connected 0 with one another at their lower ends by an axle 6 supporting the trough 2 by means of feet l2. The trough is, thus, supported by these feet, as Well as by the rolls 4. I wish it, however, to be understood that the members 1, 6 and I2 may be 5 also differently arranged, but their arrangement must at any rate be such that the trough is securely held in the position shown in Fig. 1 during the service hours.

The rod 6 serves also as a grip when the filled trough is to be emptied. This is eifected by pull- 5 ing the trough forcibly to the left (Fig. 1), the rolls 4 running then along upon the rails 5 until they arrive in the position 4' indicated by dotted lines in Fig. 1. Owing to the just described movements and, besides, owing to the trough also 10 being supported and guided by the rods 1, the trough and the other movable members assume finally the position denoted by the reference numerals 2', 4, 6' and I and indicated by dotted lines in Fig. 1. While the trough is being moved from its operative position into its emptying position it assumes also the intermediate positions shown in Figs. 3-5, but in none of these positions is there interference with the branch I. The oblique wall of the trough which normally extends upwardly, as shown in full lines in Fig. 1, is finally downwardly directed, as shown in dotted lines in Fig. 1, and the entire contents of the trough will now slide down into a cart or truck l0.

As it can occur that the trough, prior to the tilting, is not completely filled with ashes or whatever other material it may be so that a corresponding amount of water has remained in the trough, a small intercepting trough 9 is provided near the upper end of the oblique wall of the main trough 2, the arrangement of the trough 9 relatively to the trough 2 being such that when this latter is tilted only a little, the water contained in it over the smothered ashes flows away into the small trough 9 and then the large trough 2 finally reaches a position in which the ashes etc. slide down into the truck. While the trough 2 is thus being moved, its discharge edge moves along the path indicated by the dotted line .r-r (Fig. 3), from which it is evident that the two troughs never interfere with one another. The trough 9 may be designed as a mud separator.

In the constructional form shown in Fig. 1 the small trough 9 resembles somewhat a semicylinder which is closed at its ends and is there supported on pivots H. One of the pivots is in the form of a hollow trunnion open to the interior of the trough, as at H, and serves for letting the water escape, whereas the mud collects on the bottom of said trough 9. From time to time this trough is turned on the pivots I l in order to let the collected mud fall down. When the trough 2 is initially tipped into the position shown in Figure 3, the water contained therein above the ashes or other refuse will flow over the forward 5 edge of the trough into the smaller trough 9, and if desired the trough 2 may be retained in this position until a practically complete discharge of the water has been obtained.

I wish it further to be understood that the positive turning of the main trough 2 can be effected also by other members, or by another arrangement and combination of parts respectively, than by the parts 5, 6, l and 8, which constitute merely a constructional form shown by Way of example. The characteristic features of the trough 2 are first of all that it can be turned in a vertical plane and at the same time shifted in a horizontal plane, the two motions taking place without interfering with the discharge branch I, as described.

I claim:

1. A device for receiving ashes and the like from a downwardly directed discharge spout and operable to discharge such ashes at one side of the spout, comprising a movable container open at the upper end to receive the discharge spout when the container is in receiving position, guiding means for the container arranged substantially at right angles with respect to the spout, and supporting means carried by the container and arranged approximately on a horizontal axis through the center of gravity thereof for movably cooperating with said guide, whereby the container during its movement on theguide may be gradually tilted to dispose the container in discharge position wholly at one side of the spout.

2. A device for receiving ashes and the like from a vertical discharge spout, including a movable container for the ashes delivered through the spout, the upper edge of the container being arranged above the lower edge of the spout when the, container is in receiving position relative to the spout, a guide for the container arranged in a plane normal to the axis of the spout and beyond the body of the container, and elements supporting the container and arranged approximately on a horizontal axis through its center of gravity and movably cooperating with the guide to permit movement of the container laterally of the spout and simultaneously cause tilting on its horizontal axis to move the container wholly toward one side of the spout and to a discharge position.

3. A device for receiving ashes and the like from a downwardly directed discharge spout and discharging such ashes at one side of the spout, comprising a container open at the upper end to receive the discharge spout when the container is in receiving position, a guide on which the container is movable substantially horizontally, and means connecting the container and a point fixed with relation to the spout, said means compelling gradual tilting movement of the container during such horizontal movement.

4. A device for receiving ashes and the like from a downwardly directed discharge spout and for discharging such ashes, comprising a container open at the upper end to receive the discharge spout when the container is in normal position, a guide on which the container is movable substantially horizontally, and means connecting the container and a point fixed with respect to the spout, said means compelling gradual tilting movement of the container during such horizontal movement, therelation of the horizontal and tilting movements of the container disposing the container in discharge position laterally of the spout at the limit of horizontal movement in one direction.
