more uniformly than pokers heretofore used.

Further the invention aims to mount and operate 'the poker ii 'such a .way that therey is a slicin orplowing action and a slight packinge ect without causing thepoint or lower end of the poker to `haveexcessive differences in level in the-fuel bed.

A further object is to provide a construction such that the poker mechanism can be water sealed and thus made absolutely gas tight.

The poker most generally used heretofore,

i knownas the Hughes poker, is mounted on 'trunnions, and the poker proper is oscillated or swung back and forth through an arc of a vcircle lying in a vertical plane. The oscillatorymovement is a ve desirable one,

' and the present poker mec anism-is preferably such that an oscillatory movement is utilized but the movement of the poker is other than in a vertical plane. Preferably the poker is mounted and oscillatedv in such a manner that the point of the poker travels back and forth in an arc of a circle lying in a plane which is nearer the horizontal than the vertical, but inclined with respect to both so that as the poker is swung back and forth, toward the wall of the producer body and then toward the center or axis of the roducer body, it will thoroughly over the ofthe producer arerotated relatively, and at the same time the point of the poker will be slightly lower when the poker is in' its extreme positions than .in the mid osition thus producing the desirable packing effect. v Y i.

The invention may be further briefly summarized as consisting in certain novel details of construction, and combinations and arran ements ofparts which will be describedvin the speciiication and set :forth in the appendedc aims.

In the accompanying sheets of drawings, Fig. 1 is a vertical sectional view throu h a producer equipped with thepoker mec anism embodyin the. present invention;

" 2 is a top p an view of the same; Fig.

3 is an enlarged vertical sectional view taken at substantially right angles to the section ed of fuel as the body and coverv poker by will yof bolts 26 to Renewed February as, was.

vof Fig.. 1; and Figs..4, 5 and 6v are Sectional .views substantially along the line -B of Fig. 3, with the poker in -its two 10 and 11 is rotated relatively tothe other,

and in this instance the cover is stationary and the producer body is rotated, the body being supported on rollers, one of which is shownlat 12 engaging a track 13 surrounding the producer body. The producer body maybe rotated-by any suitable mechanism, but ini this instance it is surrounded by a gear 14 which is engaged Aby and rotated by a pinion l5 on a .vertical shaft 16 alongside the producer body. .l

The top of the producerbody and the peripheral` ortion of the cover are watersealed int e customary manner as shown 'at drawings, 10 repi 17. Additionally any suitable charging apable way as by means 'of a i e or conduit 18. p P

The poker '19 with which the resentiini vention is involved, is preferab from end, to end, and. asy here cludes a main hollow bod a removable tip 20 at its lo y straight shown, in-

wer end, and

with a cap 21 at its upper orouter end. The

Esker is preferably water-cooled, the water ing conducted down to the'lower end or tip of the poker by a pipe y22and, being conducted rom the bodyv portion of ,the

chars into the cover, and from which there one or more overiow voutlets tothe trough of the main water seal at the top of the producer body.

a dischargefpipe 23 which disportion with' The upper part of the pokerA is seatedv l and fixed in `a suitably formedsocket of an oscillatory head 2,4, though the oker can be readily removed from the hea -by slipping it in an endwise 4direction out from', for repairs and the like.. The head 24 ,is journaled in 'a cylindrical normally fixed' bearing 25 which likewise can be removed but is there-v normally secured by a series an annular or lsubstantially annular upstanding seat 27 of the producer 4cover 11.

from the cover. This ange is surrounded by a` larger and somewhat similarly shaped depending flange 30 on the head 24 carrying the poker. inasmuch as the shape of; the cover, clearly shown in Fig. '3, is'vsuch as to provide a depression around the flange 29, it is apparent that a very effective water sealis thus provided, and that gas will not escape from the producer around the poker.

It is to be noted, particularly by reference v to Fig. 3, that the poker is set into the oscillatory -head 24 at an angle to the latters axis so that when the head is oscillated, the point of the poker will swing through an lare of a circle in a plane normal to the axis of the head 24. It will be noted also, that the axis of the head, 'and likewise the axis of the'bearing 25 are inclined to the vertical or to the axis of the producer, that is, the axis about which the head 24 turns lies in a plane other. than the horizontal. By reason of this novel construction and arrangementnet-onl will the point of the poker swing throug the arc of a circle when the head. is oscillated, but the plane containingthe arc of the circle being normal to the inclined axis of lthe head is inclined both tothe horizontal and the vertical, the inclination with respect to the l horizontal being equal lto the inclination of the oscillatory head with.respect to the vertical.

By reference to Figs. 1, 2 and 3 it will be observed that the point of the poker swings as the through an arm of a circle extending Arom a point near the producer axis to a point near the upright wall of the producer body. As the pokeris oscillated in this fashion at rthe same time that the producer body and bed of fuel are rotated in the direction indicated by the arrow of Fig. 2, it is obvious that the fuel bed will be very completely covered by the cker, a slicing or plowing action being obtained due to the inclination of the poker. In this-respect the present invention is an improvement over poker mechanisms heretofore contemplated wherein the poker is given a complete rotation about a vertical axis.

Likewise it 'will be noted that inasmuch plane of movementof the point of the poker 1s inclined to the horizontal and the oint of the poker oscillates through anarc 1n the upper portion of a circle in said plane,

the point of the poker will be slightly deeper ,when at the limits of its movement rather "than at anyY intermediate point, so that as 'the poker is oscillated, the plowing or slicing a maximum'degree the advantages of prior constructions, and possesses to aminimum extent their disadvantages.

The poker may be oscillated in dierent ways, but in this instance the shaft 16 which rotates the producer body is provided at its upper end with a pinion 31 which meshes with, and rotates a gear 32 having a crank pinv 3-3 connected by a connecting rod 34 to a crank arm 35 extending laterally from the poker head 24. rlhe pinion 31 and gear 32 are slightly beveled, and the gear 32 is set at an angle with reference to the axis of the pinion 31, which angle corresponds to the inclination of the poker head 24 in its bearing 25, in consequence 'of which the gear 32, connecting rod 34 and crank arm 35 lie in the same plane, and freedom of movement is obtained. I Y

Modications may, of course, be-made not onlyin the construction of the poker mechanism, but in the degree of movement which is imparted to the poker proper. For a poker designed to have the extent of arcuate movement illustrated, a water seal flange 29 of the shape Iillustrated in Figs. 4, 5 and 6 may be employed, but ifl the poker he given a greater arcuate movement than that contemplated byfthe present design, the inner water seal flange 29, and, of course, also the outer water seal flange 30 will be-shaped so as to permit the full movement desired.
