SAMUEL IB.-SHELDON, {0F DULUTH, MINNESOTA.

.GAS-PRODUCER.

- Be it known that I, SAMUEL B. SHELDON, a citizen of the UnitedStates, and resident of Duluth, in the county of St. Louis and State 'of Minnesota, have invented certain new and useful Improvementsin Gas-Producers, of which the following is a specification. 4

This invention relates to gas-producers. One of the objects of this invention is to simplify and improve means for disturbing the fuel in the coking zone for maintaining condition.

-- Another object is to improve the fuel pokers and the means for actuating the same.

Another object is to provide a gas producer having cooperative parts arranged to meet all the requirements for successful operation.

These and other objects are accomplished I by means of'the arrangement disclosedby the, accompanying sheets of drawings, in.

which Figure l is a plan view of my gas producer. Fig. 2 is a fragmentary View of the upper part of the same, and

Fig. 3 is a vertical sectional view ofthe fuel feed and-distributing arrangement.

The various novel features of my 'inven tion will be apparent from the following description and drawin s andwill be particu-' larly pointed out in e appended claims.

In view of the fact that my inventionrelates to mechanism mounted on the topjof the gas producer, only the upper part of the gas producer is shown.

The main body portion 1O of the gas producer has at its upper end a channel portion 11 in which the vertical flange 12 of the rotating top 13 moves. The top and the v parts mounted thereon are all actuated through suitable mechanism by an electric motorl l, the shaft of-which is provided with the pinion 15, meshing with a gear 16 mount ed on a shaft connected to suitable gearing ,within a gear "housing 17. Extending outward from this housing is a shaft 17 carrying a pinion 18, .which meshes with and drives a" relatively large gear 19, mounted upon a shaft '20 to the outer end ofwhich issecured'a traction wheel 21 bearin u'ponthe stationary body portion 10 -o the gas producer, whereby the top of the gas producer is rotated. Secured Specification of Letters Patent. Patented Aug, 24, Application filed June 11, 1918. Serial No. 239,361.-

By means of this eccentric drive arrange vertical sectional the poker shown-at the right of the center of the gas producer. By means of this arran ement the outer annular portion of the b. including tl i at in the'coking zone, being dis the top..

to theother end'of the shaft 17 is an eccentrlc 22 (see Fig. 2) ope'ratively connected to a yoke member 23 secured to a shaft 24 upon which a walking beam 25 is. mounted.

ment the opposite ends of the walking beam 25.are given a rising and falling movement.

- Secured to each-end of thewalkin beam 25 is'a ball socket 26 in which is movab y mount- 'ed'a-ball 27, the latter of which maybe in asingle piece for in a plurality of pieces.

Extending upwardly from the ball 27 is a tubular portion 28 and extending downwardly vfro' m the ball 27 is another tubular portion 29, there being an opening through the mam part of the ball 27 registering with the opening in the tubular portions 28 and 29. Extending through these openings is a thzgeaded portion on a shank 30 of the poker.

The lower end of the poker is not shown,

' but it will be understood that the poker per- The ball and socket joint for thep'oker is the same -at each end of the walkingbeamh In.

poker to the left of the centerof the walking beam, as shown in Fig. 2, is located farther fromthe center of the gas producer than is.

fue -'bed is disturbed by the outer poker and the inner annula-r portion .of the fuel bed is; disturbed the inner poker, all' f the fuel,-

turbed during one complete revolution of By means of theball and socket joint con-.

nection between the'wa'lkingbeam 25 and-100 V the shanks ofthe pokers, the pokers are free to drag a certain amount as 'the top of'the gas produceris rotated and at the same time the poker is free to move in a line coincident movement of the walking beam 25. As shown, the walking beam 25.-is in central positioirf Let it". be assumed," however, that the actuating shaft 17' is moving in a clockwise direction, as viewed in ig; 2. Accord- 110 with or parallel to? the vertical plane of;

. 35 a this connection it will be noted that the j same uniformly porous.

ingly, the one arm of the walking beam will be depressed and the other. arm of the walking beam will be raised. In view of the fact that the connection between the walking beam and the poker is more clearly shown walking beam 25, the poker follows the beam but falls as a result of its own weight,

and regardless of the extent of downward .movement of the arm of the walking beam, the poker will extend into the-fuel bed only an amount in accordance with its own weight. Inactual operation, when the end of,the arm of the walking beam is in its lowermostposition, the nut M of the poker shank 30 may be out of engagement with the upper eiidof the tubular portion 28 of the ball ii'fl Thisis due to the fact that the fuel has offered resistance to the downward movement of the poker to-the extent that the latter was not able ofits own weight to follow the walking beam forits full throw. If. however. it is desired that the poker should be positively thrust down int-o the fuel bed for breaking the same down or for any other reason, the walking beam 25 and the shank30 of each of the pokers may be positively connectedby link or clevis means 33' parts of which may extend through openings .32 and in the tubular member 28 and the nut 31. respectively. g

It will he understood that the top 13 of the gas producer revolves continuously and at a relatively slow rate. Asa result thereof, during the up and down movement of the pokers while they are inthe fuel'bed, the bottom of each of the pokers is caused to lag a certain predetermined amount thereby pressing the portion of fuel being .pQ-litttl circumferentially in advance of the poker a slight amount. This action takes place throughout the whole revolution,

' thereby treating all parts of the coking zone of' tlie fuel bed the same and rendering the It is to be understood that'the oppositely acting pokers are raised above the fuel."then move vertically down into the fuel and while still in the 'fuel bed laga given amount beforethey are raised out of the fuel as the top of the producer rotates By adjusting the nuts 31 on the shank 30 of each of the pokers. the ver-' tical mo'yementof the latter into the coking zone maybe varied.

The shank 3d of each of the pokers is hollow. whereby a cooling medium. such as ivater, may be supplied thereto through a suitable supply connection 3-]: and from which the excess amount of cooling fluid may pass through an overflow connection 35. Secured to the lower tubular portion :29 of the ball 27 is a skirt 36 extending down into an annular channel member 37, secured to the top 13 of the. gas producer, whereby a water seal is formed to prevent the'escape of producer gas through the opening 38 through which the poker shank 30 extends. 1

Mounted on the top 13 of the gas producer is a fuel-hopper-39 which receives its supply of fuel through a chute t0, the upper end of which is in register with the supply opening 4:1 of a coal bin l2. As shown, the outlet 41 is arranged concentrically with respect to the gas producer and the fuel hopper 39 arranged eccentrically with respect to the center of the gas producer. the chute it) accordingly being arranged at an angle. It will be appreciated.however, that these parts may be arranged in accordance with requirements While I am claiming'the coal feed and distributing arrangement in a co-pending application. I will describe in a general way in this'application. the general arrangement ofthe parts. a The coal hopper 39 preferably is divided into two compartments l3 and H. separated by a central wall +5. Mounted in each of said compartments l3 and ell for reciprocation therein is a plunger l6 operatively connected to an arm i7 keyed to a shaft-l8 to which is connected an arm 49, connected in turn to a rod 50, one end of which is connected to a shaft 51, through an eccentric 52, whereby each of the plungers i6 is reciprocated. It will be understoodthateach of the plungers has its own reciprocating mechanism, the latter in each case being operatively connected to the shaft 5l,"to one end of which is secured a gear 53 which is driven by gear 19. Fuel from the hopper 39 flows downwardly in frontof the plungers 6, the fuelsloping off infront of the plungers at an angle of repose. The fuel in front of the oppositely actuated plungers 46 is pushed onto. a distributer 5i, which is eccentrically arranged with respect to the vertical 61 to fo'rm a water seal inthe annular chan- Y nel members 62. -The floor 63 of the hopper 39 is water cooled as is also the partition or wall i5 between the compartments 4:3 and H.-

The top 13 of the gas producer is cooled ing circumferentially arranged openings 65 a by forcing formed therein by an annular wall 64 havthrough which the water may flow radially outward over the upper surface .of the top for cooling the latter. The excess amount of cooling water supplied in this way may overflow the sides of the gas producer;

There may be various modifications of .my

.invention, as herein particularly, shown and described and it s my intention to cover all one direction and moves in a suchmodificationswhich do not involve a departure from the spirit and scope of the invention, as set forth in the following claims.

I claim:

1. In a gas producer, the combination of a walking beam,-and pokers mounted on op-y posite sides of the center thereof I for disturbing the fuel in the coking zone;

2. In a gas producer, the combination of a walking beam mounted for'rotation and having arms of different lengths, and pokers mounted thereon at different distances from the center, having different paths of movement. r

3. In a gas producer,the combination of a walking beam, anda poker having an up and down movement and connected to the walking beam by a ball and socket joint whereby the poker may have freedom of movement in-a plurality of directions.

4. In a gas producer, the combination of a walking beam, eccentric means for actuating said walking beam, and apoker mounted on .water into 'a central chamber said beam for disturbing the fuel in the coking zone. 1 I

5. In a gas producer, the combination of an actuating member, and a poker having an up and down movement and connected to the actuating member/by a ball and socketjoint whereby the poker may have freedom of movementin a plurality of directions. 6. In a gas producer, the combination of a walking beam, a poker connected thereto whereby the poker is positively moved in difierent direction .under the influence of its own weight, and means whereby the poker.may be positively actuatedin said different direction.

7. In a gas producer, the combination of a lifting member, and a poker slidably connected thereto whereby the latter in its downward movement follows the actuating member under the influence of its own weight and continues, until it is stopped by the resistance of the fuel bed or by-the actuating member.

8. In'a gas'producer, the combination of a rotary top, a walking beam mounted thereon, and pokers connected to said walking beam whereby the pokers travel for disturb-' in fuel in a circular path. I

bigned'at Duluth, Minnesota, this 3rd day of June, 1918..
