Application led December 31, 199.' Serial No. 535,798.

To all whom 'it 'may concern:

Be it known that I, JOHN A. WLDBURGER, a citizen of' the United States, residing at- McKeesport, inthe county of Allegheny and State of Pennsylvania,V have invented certain new and useful Improvements in Gas- Produ'cers, of which the following is a speciication, reference being had therein to the accompanyin the outer portion of drawing.

'M`y invention consists of an improvement in gas producers, more especlally the class of water-seal gas producers, and refers 'particularly to means for agitating and discharging ashes from the lower portion of the producer.

The invention consists of a rotatable hearth having laterally arranged wings so arranged as'to sweep the ashes outwardly in a' lateral direction into annularly arranged receivingcavities on the' foundation and also into receiving vessels or chambers,v

below the water level, hereinafter described.

Referring to the drawings Figure 1 is a vertical sectional view of the lower portion of a. gas producer constructed in accordance with my invention indicated on the line I, I, of Fig. 3. Fig. 2 is a detail sectional view of one of the sweeping blades indicated by the sectional line II, II, of Fig. l.. Fig. 3 is a horizontal sectional view indicated by the line III, III, of Fig. 1. Figs. 4 and 5 are detail sectional viewsillustrating inclined arrangements ofthe sweeping blades, indicated by the section lines IV. IV, and V. V. of Fig. 1.`

The producer 2,.as `shown in the drawings, is usually cylindrical in cross section provided with the customary charging hopper, having suitablefeed mechanismand gas as shall b e more fully outlet, and if`desired, any convenient mecha- Vnism for stirring the contents (not sho-wn), although the ,latter feat-ure is not necessarily essential.

3 is an annular wind box surrounding the base portion of theproducer immediately below its 'walls and inwardly disposed construction.

4 is a centrally arranged cone mounted on provided with numerous the hollow fpost 5, in connection with air supply mechanism, and adapted to deliver volumes of air and steam laterally toward the charge.

6 is a stationary hearth located centrally vvals by vert-ical annular posts air ports of well known l at the base portion of the producer, of conidownwardly and voutwardly toward the, surrounding receiving cavities 6', 6, at opposite sides of the; stationary hearth, said cavities'being partly annular in form, between the edge' of the stationary hearth and the base wall 7 of the producer structure.

8, 8 represent water-sealed compartments for the reception of the ashes, into which they may be delivered, or receiving buckets, or suitable vessels 9 may be set therein between the ends of annular cavities (ia and below the level thereof for the same purpose. Said vessels may be removed when filled and re-inserted, or the ashes may be withdrawn from the pits 8 in the usual way. The cavities 8 contain water as shown, the seal being effected by downwardly extendin partitions below thelevel of the bottoms of cavities,

' Rotatably mounted upon the upperface of the stationary hearth 6, is a correspondingly coniform shaped open. frame or spider 10, centrally journaled around pipe 5, of any suitable construction, as an open casting having approximately radially arranged arms 11 and a surrounding annular ring 12 with intervening open spaces. Above said ring 12, and connected therewith at int'er- 13, isI a sup-v porting ring 14E mounted by an 'annular flange 15 and rolling bearings 16, upon an annular supporting ledge or ange 17 secured within the cal-sing 7. The said ring is provided upon its upper face with gear teeth '18 into which, at any suitable point, meshes a driving pinion 19 actuated by any suitable gearing or driving mechanism, not necessary to be described in detail.

Extending upwardly from arms 11 of the rotatable spider 10 across the vertical distance intervening between it and the lower edge of the inner terminal ring 20 of the producer below the air Supply structure, are a series of ash discharging wings 21, while at any suitable point or points, and preferably at two om `asite positions, are extended outwardly and downwardly across and into the annular spaces 6^, by means of Wing extensions 22. Said wing extensions, as shown in Fig. 1, 'practically fill said annular space as the spider 10 ro tetes so as to sweep the ashes therein l'alongthe bottoms of the ledges ofithe foundation the Wings 21 i and of cavities 6* into the chambers 8, or receptacle 9, as shown in Fig. 3. ` Wings 21 and 21 arearranged in a enerally radial position, but at .a slight inc inationfrom a true radial arrangement, so that as the spider lO rotates in the direction of arrow a, t

into the chamber or vessel as stated.

It will be understood thatb the rotatable hearth is actuated at. comparatively slow speed and as it performs its functions the upper'edges of the wingswill gradually dislodare the' ashes from above'to effect their falliso that the necessity of any poking or stirring of the fuel in combustion is largely or altogetherlobviated. tion of the'movable spider may be easily regulated as desired, and in proportion to the .charge of coal in the producer.

lVhile the wings 21, 21', and 22 may ordinarily'be vertically disposed with good results, they may also be inclined Aforwardly toward their lower edges, as shown in Figs. 3 Vand 4, whereby the wings 21 will more eectually engage the .ashesl ing on the sloping surface of hearth 6 or wings 22 will easily scoop the ashes along the bottom of cavities 6l and into water sealed chamber 8 or vessel 9. It will b'e observed that all of the ash supporting surfaces are above the wa'ter level and eifec'tually sealed from the outside by the downwardly extending partitions 7 It will be understood that the design or arrangement of'the .rotatable spider discharging wings, and the other several features or details of construction ma be chan ed to suit diilerentconditions o use, buta l such changes are to be considered as within the scope of the following claims What I claim is i 1. A gas producer provided ,.itn a stationary hearth, a rotatable s ider lying upon and conforming to the sur ace thereof having ash-dischargin wings radially separated from each ot er b intervening segmental openings, and means independent of the heart for rotating the spider.

2.
