Specification of Letters Patent. Patented June 20, 1911,

Application filed August 5, 1908. Serial No. 447,048.

. To all whom it may concern:

Be it known that 1, WILLIAM B. CHAP- MAN, of Brooklyn, county of Kings, State of New York, have invented certain new and useful Im rovements in Gas-Producers, of which the ollowin is a full, clear, and exact specification, suc as,will enable others skilled in the art to which it appertains to set forth hereinafter arid particularly pointedout in the claims.

Reference is had to the accompanying drawings, which illustrate as an example .one manner of practically. embodying my invention, in which drawings,

Figure 1 is a vertical section of the aparatus; Fig. 2 is-a sectional Ian on the inc 22 of Fig. 1; and Fig. 3 is a vertical section showing the upper partof another form of the device.

Referring to Figs. 1 and 2 the producer is there shown as constructed of a metal shell 10 with abrick or other non-conducting lining 11. The shell of the' producer is constructc the intermediate second section '14 revoluble, the third section 15 stationary and the bottorn section 16 revoluble. The stationary sections are suitably supported on the floor 17 by stanchions 18 from which brackets 19 proiect to'and are fastened on the stationary sect ons." The producer has an air inlet 20 at'the bottom and a as outlet 21 ,passing through the walls 05 the top section 12 immediately below the l charging floor 22. Said top section carries a coal hopper 23 with a suitable feed spout or other means 24.

The hopper tapers downward into the body of the producer and terminates in a Waterof four sections 12, 14, 15 and 16 of whic the top section 12 is stationary,

The track 28 runs on rollers 29 carried by brackets 30 projecting from the stanchions 18 and in this manner the rotating member 14 is supported with a suitable clearance between the sections 12 and 15 so that it ma revolve without friction. With the gear 2 a pinion 31 meshes which pinion is fast on. a rotating vertical shaft 32 carried, for example. in a bearing 33 attached to the sec-' tion 12 at the top end of the shaft and in a step bearing 34 arranged in a-pit 35 constructed below the base line of the roducer. For. imparting motion to said she t I" have shown a worm wheel 36 together with a worm 37 connected with a suitable source of power. At the lower edge of the top section 12 an annular skirt 38 is arranged which projects downward into the water cup 26 and this cup being filled'with water, a seal is formed which prevents the escape of gas between the sections at this point. The r0- tating section 14 also carries a downwardly projecting skirt 39 which dips into a cup 40 attached tq the stationary section 11, forming a waterseal between the bottom of the section 14 and the top of the section 11. The coal from the hopper 23 ravitates through the throat ring 25 and lies in the body of the producer witha conical top surface which ifnndisturbed would assume the, normal angle of repose. The coal, however, is-leveled out and spread uniformly over the fire by means of a coal spreader 41. This. coal spreader is in the form of an iron pipe and its ends are passed through the walls'of out so that water may be circulated through it to cool the same and reventits destruc' tion by the fire. From .t 1e middle or center u of the goal spreader a. pipe or tubularshaft 45 passes upward, this pipe being securely attached to thecoal spreader to rotate there with and extending centrally throughthe hopper and through a stuffing box or other seal 46,.so that steam generated within the..

hol lowwnoal spreader 41 may escape from the producer without mingling witlrlthe as" en erated therein. The pipe 45 serves t e, urt-her function of supportin the coal agitator 47. This, as is shown in curved and has a pipe in proximity to the tapering bottom of t. e hop- 1g. 2, is reversely. hub attached to-the pipe45 at a point within the hopper and extendsjupfward, from opposite si es of the per so that upon the rotation of the section jects down into the water one 48 to form a water seal at the lower end or the. section 15. Said casing has at its'inner side an annular sheet metal wall 55 forming the inner wall of the cup 48 and at the lower edge of the casing a tapering sheet metal skirt 56 is secured, the same projecting downward and tapering inward to a point considerably be low the upper edge of the ash pan 57. -Said skirt 56 forms part of the section 16 and re volves therewith and it carries a number of stanohions 58 projecting upward-within the section 15 and also rotating with the section 16. To the upper ends of these stanchions a rir, 59 is joined and this ring supports the med ash plows 60. Of these plows there preferably four'a'nd the same have the cross sectional form indicated in Fig. 1 so that they will exert an upstroking action in the ash bed just below the incandescent'or fire zone and agitate the same through the medium of the upper part of the ash bed for the purpose of preventing the formation of blow holes in the fire and insuring a compaot body f-incandescent coal. By agitatlng the fire-,through the medium of the plows described the formation of large clinlrers is avoided due to the thorough and continued breaking upjof the molten matter of which the clinkers are formed. At their innerends centrally in the producer the plows 60 .upport ahead 61, the top surface of which is pyramidal in form and which hood rotates with the section '16. The hood covers the open upper end of the stationary blast nozzle and clinker crusher 62 This is mounted in the bottom'of the ash pan and is of square or other angular cross sectional form with the result that-the ash body inclosed in the skirt 56 and rotating with the same will be continually thrust against the angular nozzle v62 serving to crush or break. up the clinkers in the ash body and facilitatin the removal of the ashes from the pan. The mid 61 in rotating with the plows 60 exerts an agitating action on the ash bed similar to that of the plows themselves. 1 The nozzle 62 communicates wit the pipe line20 supplying the air blast w ich air blast passes out the open upper end'of the nozzle under the hood and upward into the fireQ Water is supplied to the varioir ii water seal. cups and to the ash pan in any desired manner and it may be arranged to flow constantl overflowing from one cu into the ot ier and finally reaching the-as pan which it fills for thepurpose of forming a water seal through -'which the ash may be removed without coal 5: xoat of the hopper. station 14 causes the spreader 41 to sweep over the top of the fuel bed-and level out the coal as fast'a-s .fed from the hopper, the level of the fuel being "kept approximately at the elevation of the spreader. The sec- 16, however, causes a bodily rotation c2. the lower part of the ash bed grinding the same against the angular nozzle 61 which breaks or crushes the clinkers and allows the ready, removal of the ashes. Also, by the operation of the plows 60, the top part of the ash bed is given an upward agita'tion which is communicated throughtheashes to the incandescent coal, packing the 7 same and insuring a uniform fire as explained. In connection with this arrangementit is important to note the location of the plows within the stationary section 15 and the rotation ofsuchplowsthrough the medium of the section 16. This is an important feature of the invention and is one which has never been heretofore attempted. The ash is gradually settled tothe bottom of the pan and, owing to the tapering form of the nozzle 62, it is, by the rotation of the section 16', slowly worked out to the edge portion of the pan and may there be readily removed by an attendant shoveling outthe ash. The air is either drawn or' forced in'through the nozzle 62 according as to whether the producer is operated on the suction or passes upward t rough theinca'ndesccnt coal 4 and after undergoing the usual reactions with the fuel, isformed, with thfuel, into gas which is finally. carried otf'th'rough the conduit21. 1 1 The modification shown'in Fig; 3 involves a somewhat simplified construction in that it omits the charging hopper, agitator arms a'nd'coal spreader forming part of the struc-' ture shown in Figs; 1 and 2, and by reason of the omission of the coal s reader, the per rotating section of t e 1 producer 1s made sufficiently deep to bring about an pressure principle' The air.
