The invention relates to an apparatus for feed ing the fuel into gas producers and especially into coal-gas producers from a fuel bunker situ _ ated outside the gas producer by means of a 5 feeding arrangement which distributes the fuel over the whole section of the gas producer. The principal object of my present invention is to provide such improvements in the feeding arrangement of gas producers so that the fuel 10 is distributed uniformly and automatically over the whole fuel bed in exact adjustable quanti ties, quite independent of the quality, i. e. the grading, composition, speci?c gravity and mois ture of the fuel and without the segregation of ' the fuel. The cover 3 is moved by means of a tooth wheel 8 which sits on the driving shaft 1. The tooth wheel gears into the tooth rim 9 of the gas pro- ; ducer cover}. The fuel to be gasi?ed is delivered from the stationary bunker I ll into a feeding hopper II, which is arranged centrally upon the rotating gas producer cover 3. A box wheel I2 is con 10 nected in a gas-tight way to the feeding hopper II by means of which the fuel is delivered in exactly measured quantities from the hopper H to the feeding pipe IS. The vertical feeding pipe 13 is connected to a horizontal feeding pipe I4 15 tion of the fuel does not cause any trouble in the feeding arrangements. provided a chute I6 which is ?xed to a shaft l1 The principal feature of the invention is char acterized by providing between the charging hole reaching through the gas producer roof. The feeding pipe I4 is so designed, that its section, as shown in Fig. 1, is permanently ?lled with the fuel which is pushed gradually through the feeding pipe M by means of the piston l5, whereby at every forward stroke of the piston a part of the fuel which has been fed by the box wheel is caught by the piston and then delivered into the feeding pipe l4. After the quantity of 30 fuel has been fed into the feeding pipe, resulting from the forward stroke of the piston, a corre sponding quantity of fuel falls at the end of the are gas-tight and so designed, that any con densation of vapours produced by the gasi?ca in the gas producer roof and the box wheel ar 25 ranged in the usual manner at the bunker outlet, a gas-tight horizontal feeding pipe, through which the fuel will be led by means. of an oscillating piston having an adjustable stroke in such a way that the feeding pipe is permanently ?lled with fuel during the operation. Furthermore, there is provided according to the present invention besides the fuel path formed by the automatic feeder a second fuel path, be tween the bunker outlet and the charging hole of 35 the gas producer roof. By means of this second fuel path it is possible to feedthe fuel in ad . justable quantities very quickly into the gas pro ducer in order to cover if necessary any ?re on the fuel surface and to avoid any damages re sulting therefrom‘. Still further objects of my invention may be taken from the following description of a pre ferred embodiment of my invention shown on the 45 tight sealing between the rotating cover 3 and the stationary gas producer roof. in which is provided a reciprocable piston l5 which suitably takes up the whole section of the pipe M. The feeding pipe l4 ?nally leads into the charging hole 4 of the gas producer roof: Underneath the charging hole 4 there is also Another object of my invention is to provide im provements in which the feeding arrangements 40 (Cl. 214—35) accompanying drawings in which Fig. 1 shows a vertical section through the feed ing arrangement for a gas producer. Fig, 2 gives a top view of the arrangement illus trated in Fig. 1. 50 The gas producer shaft 2 in which is placed the fuel bed I, is sealed at the top by a rotating cover 3 in which is arranged the fuel charging hole 4. The gas producer cover is supported on rollers 5 in the stationary part of the gas 55 producer roof. A cup sealing 6 ensures the gas 20 feeding pipe through the charging pipe 4 onto 35 the distributing chute IS. The coal plug which is permanently kept in the feeding pipe [4 seals the fuel feeding arrange ment against the atmosphere. Any condensa tions which for instance are formed by the tarry substances and which escape from the coal during 40 the gasi?cation process cannot cause any trouble in the coal plug of the feeding pipe l4. On the other hand, it is impossible for the gases and vapours which have been formed in the gas producer to escape into the open air, as 45 the coal in the feeding pipe M as well as the box wheel 12 offers a sufficiently high passage resis tance to the gas. The movement of the delivery piston I5 is performed by a double lever l8, which fits with one arm into the cutting IQ of the de 50 livery piston l5. The lever I8 is supported on a shaft 20 which is put into an oscillating move ment by means of an electric motor 2| by mak ing use of the crank shaft 22 and the rod 23. - The lever 24 is ?xed at the other end of the 55 2 2,113,015 driving shaft 20. A horizontal rod 25 is con nected to the lever .24. A pawl 26 is ?tted to the rod 25, which interlocks into the usual tooth rim 2'! of the box wheel in such a way, that at any cover for the drive of the various feeding devices. The current is supplied by a suitable sliding con tact by making use of a pipe 42, which is ?tted to the stationary bunker H! in the center of the movement of the rod 25 upon a forward stroke of the piston 15 the box wheel is moved on to a certain extent and on retractive movement of gas producer cover and ?xed to a hopper cross the piston !5, rod 25 and its connections merely idle. 10 As shown in Fig. 2, a second pawl 28 is arranged at the other end of the rod 25, by means of which the distributing chute I6 is set into opera tion during the forward stroke of piston 15 and merely idles during the retractive stroke of 15 piston 15. A hand lever 29 is ?rmly ?xed on the upper end of the chute shaft H, by means of which the chute I6 can be rotated. A lever 3|] is further loosely supported on the shaft ll, which can be 20 ?rmly coupled with the hand lever 29, by means of the removable pin 3!. The lever 30 carries a roller 32, which is situated within the range of a cam plate 33. This plate is turned by the pawl wheel 34, by making use of the worm 35, and the 25 worm wheel 36. The cam plate 33 is so designed, that the chute I6 can be moved by the rotation which has been transferred from the cam plate 33 onto the lever 38, so that the end of the chute [6 during the 30 operation of the gas producer, i. e. at that time when the gas producer cover is rotated and the chute moved has to go the way as indicated in Fig. 2 by dotted lines 35. Furthermore, the curve plate has been thus constructed, that the oscilla to U! tion of the chute can be retarded towards the fuel bed, so that equal quantities of fuel are distributed over every surface unit of the fuel bed. Sometimes it happens during the operation of brace arranged in the hopper H. Said hopper cross-brace carries at the same time the current feeding cables. The sliding contacts are housed in the casing 43, so that an easy access from out side is rendered possible. 10 I have described my present invention in con nection with the preferred embodiment thereof, but my invention is not limited in all its aspects to the mode of carrying out as described and shown. The invention may be variously embodied 15 within the scope of the following claims. I claim: 1.

These points have then to be covered with fuel as quickly as possible, in and to idle on its retractive stroke, and auxiliary fuel feed outlet and gas sealable conduit means 40 order to maintain a uniform composition of the gas. For this reason, I have arranged according to my invention a special fuel path in the feeding 45 arrangement. This fuel path consists of an auxil inlet but by-passing the measuring means and the iary outlet 31, which is provided for at the hop per ll. Said outlet is regulated by a valve 39, which must be operated from outside by the hand lever 38. The auxiliary outlet 37 leads to space 50 40 which is ?tted at the top of the charging hole leading from the upper hopper to the charging fuel-feed pipe. 2.
