To all whom it may concern:
Be it known that I, CHARLES A. SGHRANZ, a citizen of the United States, residing in Philadelphia, county of Philadelphia, Pennsylvania, have invented certain Improvements in Gas Producers, of which the following is a specification;
My invention Vrelates to certain improvements in gas producers ofthe type in which a stirrer bar is rotated'to agitate material inthe upper portionv of the fuel bed. rIheJ invention relates especially to a type of gas producer in which two stirrer bars are used, one movingv in a circular path within the path of the other.
The object'of my invention'is to construct the mechanism so Ithat the fuel bed at and near its outer surface will'be agitated in the same proportion as the center.
This object I'attain in the following manner, reference being had to the accompanying drawings, in which:
Fig. 1 is a plan view of my improved gas producer;
Fig. 2 is a vertical sectional view on the line 2 2, Fig. 1 g n Fig. 3 is a diagrammatic plan view showing the paths of the two stirrer bars in making one complete revolution of Ythe gas producer;
Fig. 4 is a diagrammatic 4plan view showing the paths of the stirrer bars in making three complete revolutions of the gas producer; and
Fig. 5 is a sectional plan view of a modification of the mechanism for carrying out my invention.
Referring to the drawings, 1 is the body of the gas producer, which has, atits upper end, a ring 2 forming a water seal with a flange 3 of a top section 4 supported on `beams 5 at one side of the producer. In the present instance, the top plate is stationary and the body portion is rotated by any suitable mechanism. 6 is a feeder for fuel having a hopper 7. 8 is the gas outlet. 9 and 10 are two stirrer bars mounted, respectively, in bearings 11 and 12 of any suitable construction. These stirrer bars are hollow and are curved at the lower end, as shown in Fig. 2. A water pipe 13 extends into each stirrer bar and water is circulated through the stirrer bars so that they are kept c ool. l
It will be noted that the stirrer bar 9 is nearer the center of the gas producer than the stirrer bar 10. On the stirrer ybar 9 is a worm wheel 14, which'meshes` with a single screw worm 15 on a shaftllmounted in bearings 17 in the frame 18 locatedon the ytop section 4 of vthe gas producer. Secured tothe stirrer bar 10 isa worm wheel 19, which meshes with a double lscrew worm 20, also secured to the shaft 16. The `feeding mechanism isfdriven through bevel gear- Ving 21 from ythe shaft 16, as clearly shown in -F ig. 1.-"This feeding mechanism form no part of the present invention.
The shaft 16-in the present instance, has a sprocket wheel 22 fat one end,"which is driven "from any sui-table power driven lshaft so as to'impart movement to the'shaft 16. By making the worm 2O in the form of a double screw and twice the pitch of the worm 15, the stirrer bar 10 is rotated separately around its Own axis -at twice the speed of the stirrer bar 9.
Referring to Fig. 3, which illustrates the movement of thetwo stirrer bars in one revolution of the producer, it will be noted that the stirrer bar 10 cuts the fuel bed in a path substantially similar to the path of the inner stirrer bar 9. It will also be noted that the mechanism is so timed that in making one revolution, the stirrer bars terminate at a point some distance from the point at `minates at the same point as the first convolution started, as shown in Fig. 4. This movement, as shown in Fig. 4, thoroughly agitates the fuel bed and the extent of the agitation is substantially the same at and near the outer walls ofthe producer as at of the worm wheel 14a, which Causes the stirrer bar 10a to be rotated `at twice the speed of the stirrer bar 9".
It will be understood that, in some instances, the body portion of the producer may be stationary and the top section may be rotated, carrying with it the two stirrer bars. In this instance, as the top section rotates, the outer stirrer bar will be rotated at a greater speed than the inner stirrer bar., producing a diagram similar to that illustrated in F ig. t.
While worm gearing is sho-wn as the means for rotating the stirrer bars, it will be understood that other types .of gearing may be used.
l. The combination in a gas producer, of a body portion; a top section; two stirrer bars extending into the producer from the top section, one stirrer bar being located nearer the center of rotation than the other stirrer bar; and means for separately rotatn ing the outerstirrer bar around its .own axis at a greater speed than the inner stirrer bar.
2. The combination in a gas producer, of a bodyv portion; a top Section; means vfor rotating the body portion and the fuel vbed within the lbody portion; two stirrer-bars extending through the top section and into the fuel bed, one stirrer bar being located nearer the center of rotation of the fuel bed than the other stirrer bar; and means Jfor separately rotating the outer stirrer bar around Vits own axis at a greater speed than the inner stirrer bar.
3." The combination in a gas producer, ot a body portion; means for rotating the body portion and the fuel bed therein; a top section; bearings on the top section, one bearing being located nearer the center of rotation than the other bearing; a stirrer bar mounted in each bearing and extending through the top section and into the interior of the body portion, said stirrer bars being curved at their lower ends; a worm wheel secured to each stirrer bar; .a kdriven shaft mounted in bearings in the top section; and two worms on Said shaft, one worm meshing with the worm wheel on the stirrer bar nearest to the center of rotation of the body portion, the other worm meshing with a worin wheel on the outer stirrer bar, the latter worm being double the pitch kof the former worm so that the outer stirrer bar will be rotated at twice vthe Speed of the inner stirrer bar.
