PATENT OFFICE.

In the case of devices for loading inclined retorts, one is forced to use either the To give retort houses a great height in order to arrange the coal store above the furnaces to be able to and feed the retorts from it, or in the case of deep coal storage Firstly, elevator devices convey the loading vessels up to the height of the To lift the furnace and, secondly, to empty it using other special devices.

To convert retort houses with horizontal retorts into those with inclined retorts, as modern technology strives, it often fails because, on the one hand, the height of the existing buildings do not allow the installation of an upper storage area for the coal and on the other hand, the installation of conveyors from below and in connection with it of special loading devices in front of the retorts becomes too expensive. All facilities The latter combination also suffer from the disadvantage that the fixed Unloading platforms at the level of the retorts make it very difficult to see the entire system will.

The present arrangement now constitutes an essential one in relation to the foregoing Progress. A mobile scaffolding carries the loading vessels, which in ~ a deep-lying channel extending along the furnace wall from a parallel channel Coal store mechanically fed, then lifted in front of the retorts and there automatically be emptied. *

The new arrangement is shown in the accompanying drawings.

Fig. Ι shows a vertical cross section; Fig. 2 is a front view;

3 shows a basic outline;

4 shows a vertical longitudinal section along line 3-4 of FIGS. 3 and

FIG. 5 shows a horizontal section along line 5-6 in FIG. 2.

In front of the furnace front wall b, along this, a loading channel is deeply excavated, in front of which there is a coal store 4 extending over the entire length of the furnace, over the sloping bottom of which the coal falls by its own weight into the charging vessels for the retorts by means of channel 3. These vessels hang in a mobile frame a, which runs parallel to the furnace wall on rails c and d .

At the top of the frame α , the two balanced loading (conveyor) baskets / and f ¹ hang on the disks e and are securely guided by the rollers g , which are slidably arranged on the uprights of the frame. The axis of one disk e carries the drive disk, which is driven by means of a chain, cable or belt i through the crank k to lift the coal baskets.

The conveying baskets used here are designed in a known manner (cf., for example, German patent specification 64443) in such a way that an inclined floor, which makes it easier for the coal to slide out, ends in a lower flap m , which is opened or opened by lever η. can be closed; here a movable spout o, which is articulated to the basket at ρ and is actuated by a lever q provided with locking lugs r, forms the connection of the basket

Claims (3)

the retort mouth in the loading position (see Fig. i), after emptying the basket this spout is folded back under the basket in such a way that it is Lowering resp. does not prevent you from taking up the lowest position on the ground. The device explained by FIGS. 6 to 8 is used to stop the baskets in the unloading position. A lever s is displaceable in a sector s ¹ and actuates the push rods Z, which are provided with projections uu ^l and u ² to enable the coal basket to be stopped at the level of the retort to be loaded, depending on the position of the lever s For this purpose, each basket bears an angle χ which can be set against one of the projections u . A clamping device is used so that the emptied basket, which has been lowered into the loading channel, is safely set in the loading position, regardless of the height of the upper basket during the loading of the retorts. A roll y is actuated by the crank \ by means of a pulling element /, which the latter winds up and unwinds on the drum 2. With this device, when the upper basket is fixed in the unloading position opposite one of the retorts to be loaded, the empty coal basket is safely brought into the loading position by tightening or releasing the tensioning roller. For the operation of the various cranks, the mobile scaffold carries a platform 11. From this the scaffold is also moved by a crank 8 at the same time the axis of the wheels 9, which roll on the upper rail c , and the axis of the wheels 10, which are on the lower rail d roll (see Fig. 2), actuated. As a result, the frame is moved parallel to the front wall of the furnace and each basket, which has been brought to the desired height in advance, is fed to the retort to be loaded. The baskets are filled in the loading position by pulling one of the flaps 6 turned back in front of the channel 3 and pulling the lever 7 around so that the coal can slide down from the store 4 into the basket. ^! Pat τ claims: ι. Loading device for inclined retorts, consisting of a frame (a) which can be moved along the front furnace wall, in which conveyor baskets (ff ¹ J are attached so that they can be lifted to the uppermost retort as well as lowered into a channel, which is arranged between the furnace and a coal store (4) extending along the same for the purpose of filling the conveyor baskets by the weight of the coal itself. 2. Loading device of the type protected by claim 1, in which two conveyor baskets are suspended from the two ends of a rope guided by driven rollers, the effective length of which can be changed by a tensioning device (y \) in such a way that at the lowest level of the one conveyor cage the second is in front of any retort. 3. In the case of the loading device protected by claim 1 or 2, the arrangement of the mobile scaffolding (a) in such a way that it runs on rails on the one hand on the front wall of the furnace and on the other hand at the bottom next to the coal store on rails, from the platform (11) of the scaffolding ( ^ the upper and lower running wheels of the scaffolding are actuated by means of a cable drive, etc. 1 sheet of drawings.
