GAS.- PRODUCER Application filed July 10, 1 92.6, Serial li he present invention relates broadly to the art of gas producers having to do-particularly with the delivery of fuel to and its distribution within the producer.

i In order to obtain'satisfactory operation of gas producers, it is essenti'al toeffect the delivery of fuel within the producer bodies in variable amounts, depending upon the de mands on the producer, and also in such a state of distribution that undue chilling of any portion of the producer body is not produced or that irregular} piles of fuel result.

It has heretofore been proposed in the art to whichthe invention relates to distribute fuel within the producer after delivery thereto by stirring, poking, or levelling means whereby substantially uniform conditions with respect to fuel densityand level are maintained. While the present invention is adapted for use with any of such devices,it has for one of its objects, the delivery of fuel in distributed condition to' the fuel bed, whereby in the event supplemental devices are utilized for subsequent action thereon, the work performed by such devices is minimized. Furthermore, in this manner, the sudden'del ivery of relatively large amounts of fuel to local zones is prevented whereby temperature conditions within the producer may be maintained substantially uniform.

Another object of the present invention is to provide improved feeding means whereby the satisfactory delivery of fuel is insured v without possibility of bridging of the fuel;

Still another object of the invention is to provide'improved fuel feeding means including a control 'for'the driving of at least cer; tain of the fuel feeding parts whereby under predetermined conditions of operation, the drive may be rendered ineffective,

In the accompanying drawings, there is shown for purposes of illustration only, a preferred embodiment of the invention, it being understood that the drawings do not define the limits of my inventionas changes in the construction and operation disclosed therein may be made without departing either from the spirit of the invention or the scope of my broader claims.

The desired relative rotational movement between the body and the cover may be obtained, for example, by providing a shaft 4 adapted to be driven in any desired manner as by a motor (not shown); This shaft carries a worm 5, meshing with a worm wheel 6011 a short vertical shaft 7. Also secured to the shaft ,7 and meshing with'the teeth- 8 onthe cover 3', is a driving pinion 9'.

A crank 10 may be driven by the shaft d, thereby operating a lever 11 'extendiingdowin wardl y tothe ash removal mechanism asv well understood by those skilled in the art. tending upwardly above the producer isfa similar lever orjpitman" 12' operated 'by a. crank 13' and cooperating at itsYupper 'end with a bell cran-kl ever 1d. The bell cranl lever has a pivotal mounting 15 on one side ofahopper 16 containing the main supply I offuel for the producer, Upon operation g of the 'pitman 12 itwill be apparent'that the bell' crank lever 14 is alternately rocked about its axis in opposite directions. This roching movement is in turn transmitted to. a fuel feeding member 17 at the frictional type and as shown for example in my Patent Number I 1,034,695 grant-ed Aug. 6, 1912. The construction is such that the member 17 forms a movable bottom forithe hopper directly coo-p erating with. its discharge in such manner that m upon each movement of the member 17 to the right, as viewed in Figure 1, a predetermined amount of fuel supported thereby is forced over its free edge while upon movement in the opposite direction it forms a support for the descending body of fuel which builds up thereon as determined by the setting of the adjustable slide 18 and the angle of repose of the material.

The material delivered by the feeding member 17 passes downwardly through the chute 19 which chute preferably has a. discharge outlet 20 symmetrically disposed with respect to the axis of relative rotation between the producer and the cover. From the chute 19 the fuel passes into a deflecting chute 21 cooperating with a combined feeding and sealing member 22. This member is preferably of the rotary type and is formed with diametrically opposite pockets 23 adapted to successively receive and discharge fuel.

Not infrequently, foreign material .or comparatively large lumps of coal are delivered to the rotary feeding member by the frictional feeding device 17. In order to prevent material having such characteristics from jamming or breaking the parts, I preferably provide an automatic control eflectively cooperating with the rotary feeding member whereby the movement thereof is stopped under predetermined conditions. This control may comprise a lever 24 having a pivotal mounting 25 on the deflecting chute. Pivotally connected to the lever 24 by a link 26 is a second lever 27 having a pivotalmounting 28 also located on the deflecting chute. The lever 27 carries control blades 29 and 30 while the lever 24 carries control blades 31 and 32. These blades are of such length, or are so mounted, that successive scrapers preferably more nearly approach the periphery of the feeding member 22. By reason of this arrangement, material projecting an undue amount from one of the pockets 23, will be en aged by the first control 29 and either dis odged, broken, or forced into the pocket. Material projecting a lesser amount, or material which has previously been broken by the control 29, will be engaged by the con trol 30. This action will continue progressively until all of the material is substantially flush with the periphery of the rotary feeder. In this manner, such a disposition of material is insured thatfree rotation of the feeder is permitted. In the event the projecting material is not forced into one of the pockets, or in the event it is of such nature that itcannot be broken, it will be effective through the con trols for oscillating the lovers in opposition to the counter weight 33.

This oscillation will be transmitted by the link 34 to the bell crank lever 35 having a pivotal mounting 36 on the housing for the rotary feed member. The arm 37 of the bell crank lever 35 has a pivotal engagement 38 with the horizontally extending rod 39. The rod 39, at its outer end, is pivotally connected to the lever 40 which controls the engagement and disengagement of the clutch members 41. When the levers 24 and 27 are moved in a clock-wise direction as viewed in Figure 3 of the drawings, the resulting movement of the lever 40 is such as to disengage the clutch members and thereby stop rotation of the rotary member 22.

The rotary feeding member may be driven in any desired manner, but conveniently it is driven by reason of the relative rotational movement between the cover and the producer, this driving being obtained by providing the producer with a ring gear 42 with which meshes a bevel gear 43 suitably journaled 011 the cover., Thebevel gear may in turn drive a spur gear adaptedto mesh with the gear 44 carried by the cover and constituting part of the'gear train 45; p

The gear 43 may also drive a worm .46 adapted to mesh with a worm wheel 47 by means of which the poker or stirrer 48 may be oscillated as understoodin the art.

For properly distributing the fuel as delivered by the rotary member 22 whereby the fuel bed receives the same in distributed condition substantially proportional to the relative areas determined by the gradually increasing diameter fromthe center of the fuel bed outwardly, I preferably provide the cover with a distributor D. This distributor, as will be apparent more particularly from Figure 6 of the drawings, has its face which receives the fuel, so shaped as to provide a plurality of angularly extending portions, a, b, c, d, e, f, g, and 72.. Of these, the portion 6 is so disposed that different parts thereof lie on opposite sides of the dotted line L representing the center of the fuel feeding opening through the cover of the producer. If the producer has, for example, a diameter of 10 feet, this dotted line will be so positioned that it will lie approximately 3 feet from the center of the producer and two feet from ,theouter wall, it having been found in activepractice that the outertwo feet of the fuel bed require in excess ofhalf of the entire quantity of coal supplied to theproducer. The portion 6 will deliver on opposite sides of this dotted line, while the portions 7, g, and it will all deliver outside of this line and the portions (1. b, c, and d, will all deliver inside of the line. Inasmuch as the portion a must deliver fuel the greatest distance, it preferably has the least inclination as is clearly apparent from Figure 6. The portion 6 being required to deliver the next greatest distance, has a longer face and somewhat steeper, while the portions 0 and cl are still slightly steeper.

The inclination ofthe portions 6 and f is largely utilized in deflecting the fuel directly away from the same and circumferentially of the fuel bed while the portions 9 and h are disposed in such manner as to project the fuel outwardly. The successive zones of distribution obtained by construction of the character herein referred to, are

indicated by the chain lines Z. In the diagrammatic showing of Figure 5, the rectangular opening 0 is representative ofthe opening through which coal is delivered fromthe rotary member to the distributor, and inclicates-the relative position of the parts.

I have found that by providing a frictional fuel feeding member directly cooperating with the discharge outlet of the main hopper, I obtain improved feeding results inasmuch as bridging of the coal is successfully prevented. The location of a frictional fuel; feeding member in this position, therefore, constitutes one of the advantages of the present invention. 7

Another advantage of the present invention, arises from the provision of means automatically effective for stopping rotation of the rotary member in the event foreign mate.- rial or fuel is delivered thereto under such conditions that it projects an abnormal distance therefrom. 7

Still other advantages of the invention, arise from the provision of a distributor having angularly disposed portions arranged so with respect to the amount of fuel which they must handle in order to secure uniform distribution, and having an area, length and pitch such that the'desired distributing action is obtained- I claim:

1. In a gas producer, a rotary feeding member, driving means therefor, and a plurality of means at different distances from said member for rendering the said driving 40 means inoperative under predetermined conditions. V g 2. In a gas producer, a rotary feeding and. sealing member, driving means therefor, and a plurality of means spaced from the periphery of said member and located at difierent distances therefrom for rendering said driving means inoperative under predetermined conditions. 7 V

. 3. In a gas producer, a rotary feeding and sealing member, driving means therefor, and

a plurality of means at successively decreasing distances from said member for rendering said driving means inoperative under predetermined conditions.

In testimony whereof I have hereunto set my hand. 1 REINHARDT DAAE.
