The cranks 6 are mounted on the ends of shafts 7 which are rotatably mounted in bearings 8 on top of or above the stationary section 2 of the gas reducer. Each of the shafts 7 is providewith a worm wheel!) which meshes with and is caused to rotate by suitable worms secured on the driving shaft 10. The shaft 10 is connected by slowdown gearing 11 with a motor 12, by which the movable bottom section of the producer is actuated. The top section 2 of the producer is provided with a gas outlet opening 13, and with a fuel inlet opening 14, which is ordinarily closed by means of the bell 15. Openings 16 forming peep-holes are provided in the top part of the producer, these openings also being employed for the insertion of rods used in poking the fuel bed when such poking operation is found necessary or desirable. The top cover plate of the producer is formed of a panshaped casting which is kept cool by means of the pool of water maintained therein. The openings 1-6 through the cover plate are closed by suitable covers 17 when the producer is in operation. The lower end of the top section 2 of the producer is provided with a bottom casting 18 forming an annular water trough. The top end of the bottom section 3 of this producer is provided with an inwardly and downwardly extending flange 19, which projects downwardly into the water trough formed by the casting 18,

so as to form and maintain awater seal between the stationary top section 2 of the producer and the movab c bottom section 3 and form a gas-tight joint between the sections. Water is supplied to the trough formed in the casting 18 in any desired mannor. and an overflow pipe 24 is provided by which surplus water is carried away from the trough 18, the water overflowing from this trough into the pocket 25 with which the pipe 24 is connected. The lower end of the movable section 3 of the producer terminates in a casting 20 having :1 flange 20 which projects downwardly below the level of the water maintained in the ash it 21. to provide a water seal at this poi-ntm the producer. The ash pit 21 is provided with a suitable overflow outlet 22, which maiutains the water in the pit at the desired level, and the producer is provided with aciroular bottom plate 23 in e ash it on which the ashes are supported, the as mes in turn sup porting the column of fuel extending up wardly into the upper portion of the producer. In the lower portion of the producer is a wind box 26 which is supplied with air under pressure through the pipe 27, which connects the wind box 26 with a fan or other source of air supply. The air is forced through the annular openings between the plates 28 fOl'flllI] the sectional top for the wind box 26, an rising upwardly through the ash bed into the burning fuel, assist in burning and converting the solid fuel into a combustible gas. The top section 2 of the producer is provided with brackets 29 by which the producer is carried on the supporting beams 30 extending transversely be low the top of the producer. The movable lower section 3 of the reducer is connected by a ball and socket joint with the lower end of the rod 4 and the upper ends of these rods are connected by cleviscs 31 and links 32 to the crank pins 5 on the cranks (i. The movable lower section 3 of Fig. 3 is provided at a plurality of points on its upper end with supporting rollers 33, which are arranged to turn by contact with the cam surface 34 of the rotatable ring 35. This ring, which tilts the movable section 3* of this producer, is mounted upon and rotates on the anti-friction rollers 36, which are secured in suitable bearings in the support 37. The ring 35 is provided on its periphery with bevel gear teeth 38, which mesh with the teeth in the bevel pinion 39 on the shaft 40. Mounted on the shaft 40 is a worm wheel 41, the teeth of which mesh with the worm i2 which is directly connected to the armature shaft of the driving motor 43 by which the ring 35 is caused to rotate.

The gas producer shown in Figs. 3, 3 and 4 is provided with a gas outlet opening, fuel inlet 0 ening and poking holes similar to those 5 own in Figs. 1 and 2, and a water seal is maintained between the top and bottom sections of the producer and between the lower end of the lower section of the producer and the ash pit in a similar manner to that shown in Fi s. 1 and 2, and the construction of the win box. bottom plate and stationary top section of the producer is the same as that shown in Figs. 1 and 2.

In the construction shown in Figs. 5, 5 and 6, the stationary top section 2' of the producer is mounted upon brackets and is supported by means in a similar manner to that shown in the receding figures. The movable bottom section 3 is sus ended upon rods 4" in a manner similar to t at shown in Figs. 1 and 2. In this construction, however, the rods 4" are used solely for supporting the movable bottom section 3" of the producer and rotary vertically disposed shafts 14 are provided, having cranks 45 on their lower ends for moving the bottom section 3" relativcly to the to section 2". The cranks 45 are provided with crank pins which project vcrtmally downward into the bearings 46, which are secured to and form part of the movable bottom section 3 of the producer.

The upper ends of the shafts 44 are provided with worm wheels 46, the teeth of which mesh with the worms 4.7, mounted on the shaft 48. The shaft 48 is connected by slowdown gearing 49 with a driving motor 50 by which the movable bottom section of this producer is actuated. The stationary top section of the producer is provided with gas outlet openings and fuel inlet openings, and. with poking or peep holes constructed in a similar manner to that shown in the preceding figures. The producer is also provided with a wind box and with a water sealed ash pit of similar construction to those shown in the preceding figures, the lower end of the movable section 3* of the producer projecting downwardly below the level of the water in the ash pit to provide the necessary water seal. The upper end of the lower movable section 3 of this producer is provided with an annular casting forming a watertrough, and the lower end of the stationary top section of the producer is provided with a depending flange which projects downwardly into the water in the trough so as to form a water seal.

In the modification shown in Figs. 7, 8 and 9, a gas producer rectangular in horizontal cross-section is shown, which is attached to and forms one end of a heating furnace. The stationary to section 2" of the producer is provided wit a side inlet 51 through which the fuel is delivered into the producer, and suitable openings 52 are provided in the side of the producer through which the fuel bed can be observed and stirred when necessary. The lower end of the stationery top section 2 of the producer is provided with a water trough formed by the casting 53 in a somewhat similar manner to that shown in Figs. 1, 2, 3 and i. The stationary top section 2 of the producer is carried by means of brackets 54 on the supporting stands 55. Supported below the top section 2 of this producer is a movable bottom section 3. lhc movable section 3 is provided with trunuions 56, which are mounted in bearings 57,securcd on the stands 55, so as to ermit of the bottom section 3* being rocker or oscillated. The marginal top edge of the section 3 is provided with :1 depending flange 58 which projects dowu wardly into the water in the water trough so as to maintain a water seal betwecn the stationary to section and the movable bottom section 0 the producer and prevent escape of the betweenv the sections. The lower end 0 the movable section 3 prw jects downwardly into the ash upa so as to form a water sea in a manner similacto that shown in the preceding figures. A wind box '30 is provided in the lower ortion of the producer, in this case the wind boa bcm rectangular in cross-section and being d1- vided into a plurality of compartments Q0, 60", 00, 60, 60, 60. An air pipe 61 which is provided on its one end with branches 62 is arranged to connect the several compartments in the wind box 60, and supply these compartments with air under pressure. The air is forced outwardl from the box through the o enings 64 In the sides of the wind box on passing through the ashes, finally reach the burning fuel bed located in the producer above the ash bed.

In the operation of the gas producers shown in the drawings, the fuel is supplied to the producer and the ashes are removed from the water sealed ash pit in the usual manner. After the fuel bed has been ignited and the making of gas has been started, the

lower movable section of the producer is caused to move relative to the stationary top section.

In l, 2, 3 and 4, the bottom section is lifted so as to cause a vertical movement of the fuel and ashes in the bottom section of the producer relative to the fuel in the top section and the ash bed beneath the producer.

In Figs. 5 and 6 the fuel in the lower movable section 3 is moved transversely and bodily relative to the fuel in the top section 2". By reason of the suspension rods P there is also a slight vertical movement of the lower section and its contents.

In the modification shown in Fi 7, 8 and 9, the lower section of the pro ucer is rocked or tilted relatively to the stationary top section 2, this mot-ion being imparted from the motor 65 through the train of slowspeed gearing 66, the last wheel 66 of this train having a itman connection 67 with the movable section 3*.

As the bottom section is moved relatively to the top section, the column of fuel is caused to gradually descend in the producer and finally, in the form of ashes, reaches the open lower end of the lower movable section of the producer.

When the movable section is actuated the ashes in the lower part of the supporting ash bed are moved sidewise from beneath the movable section of the producer from which pointthey are removed by hand by the operator at suitable intervals. As fuel is consumed fresh coal or other solid carbonaceous material is added to the top of the bed through the fuel inlet opening in the producers and in moving the lower section of the producer relatively to the top section one section or zone of the fuel is movct bodily relatively to another auction or zone of the fuel bed and 0 innings or holes forming through the fuel 10d are broken up and are caused to close, and in this way the fuel is caused to burn uniformly throughout the producers and the formation of lean gases is prevented.

The at lvantagos of my invention will be apparent to those skilled in the art. The movable bottom section of the producer causes the fuel to descend evenly in the producer and prevents the formation of openings through the fuel bed, such holes resulting in the formation of lean, poor ases, while the moving lower end of the ottom section of the producer causes the ashes to be gradually moved from the bottom portion of the column of ashes supporting the combustible fuel in the producer.

Modifications in the construction and arrangement of the parts may be made without departing from my invention. The manner in which the lower section of the producer is moved relatively to the top section and the apparatus by which it is moved may be changed. The construction of the water seal between the sections may be modified and other changes may be made.
