Patented June 30, 1908.

Application filed November 20, 1907. Serial No. 103,094.

To all whom it may concern:

Be it known that I, GEORGE B. FoUsT, a citizen of the United States, residing at Masontown, in the county of Fayette and State of Pennsylvania, have invented certain new and useful Improvements in Coke- Extractors, of which the following is a specification.

My invention relates to machines for draw ing coke "from coke ovens, and for other like uses. It is desirable, in most cases, that the framework and mechanism of such machines shall be such that the entire apparatus, including a delivery conveyer hereinafter mentioned, may be mounted upon and sup orted solely from a single truck of short'whee -base, so that the machine may be self-contained, easily moved on tracks whether the latter be straight or curved, and easily turned about.

It is also desirable that the machine shall be capable of delivering the coke or like material at a point considerably to one side of the su porting truck and at a level consid erablybigher than that at which the material is received, so that, for example, high-sided cars may be loaded by means of it. The machine herein described and illustrated in the accompanying drawings fulfils these requirements.

- The said machine comprises a suitable four-wheeled truck of short wheel-base, carrying a derrick-frame for the support of a cantaliver convcyer, and it also comprises the usual ram supported on the said truck and arranged to be moved into and out of the coke ovens or furnaces and provided with Owing to the fact that it is desirable to deliver the material at to su port the rear or receiving end of the said (I ivery conveyor at a level considerably above that of the said ram, and provide elevating means for receiving the material as drawn out by said ram and raising it to a point where it will fall by gravity on to said conveyor. This elevating device, according to my invention, is an annular bucket-wheel, of trough-section, entirely open at the center, that is to say, entirely devoid of spokes, so that the said Work through this open center and so that the receiving end of the conveyor may also be within this open center. This bucketwheel is "provided with buckets or shelves constructed and arranged to discharge the material carried up by them when a point over the conveyer is reached.

In the accompanying drawings: Figure 1 shows a front elevation of the machine, that is to say, an elevation of that side which, when the machine is in use, is toward the oven from which the material is to be taken. Fig. 2 shows a top view of the machine, and Fig. 3 a side elevation thereof. Fig. 4 shows a vertical section of the elevating wheel in the plane of rotation thereof; Fig. 5 a detail front view of a ortion of said rim, showing the means for he ding closed normally certain supplemental filling-doors hereinafter mentioned; and Fig. 6 a detail horizontal section showing means for adjusting said elevating Wheel. Fig. 7 is a view similar to Fig. 1, illustrating an alternative mounting for the elevating wheel.

In the drawings, 1 designates a fourwheeled supporting truck of short wheelbase, and 2 a derrick-frame thereon. At the top of this frame are transverse braces 3 upon which are mounted sheaves 4.. over which pass the ropes or cables 5 for su1 porting the outer end of the overhanging or cantaliver liver convcyer, above mentioned.

For carrying the said elevating wheel, I provide an upright rectangular frame, A, carried by the truck 1 and preferably overhung (see Fig. 3) and supported by brackets 6 secured to truck 1. Said frame A comprises top and bottom members 7 and 8 respectively and side members 9. In the con struction shown in Fig. 1, the elevating wheel is not supported directly upon this frame A, but upon a movable secondary frame B, movable from side to side (that is to say, in a plane substantially parallel to the plane of rotation of the wheel) for the purpose of adjusting the position of said wheel. In the construction shown in Fig. 7, however, this means for adjustment is omitted, the elevating wheelbeing mounted directly on the frame A. In the construction shown in Fig. 1, frame A is provided with cross-pieces 10, 10 (Fig. 1) 11, 11"

(Fig. 3) which, with bottom members 8 of frame A, form rails upon which the secondary frame B may move as described. This secondary frame B comprises top and bottom members, 14 and 15 respectively, and side members 16, and is provided with flanged carrying-wheels 17 and 18, arranged to roll along members 10 and 11, and 8, respectively, of frame A. Members 10 and 11 constitute keepers to prevent derailment of -rame B. Frame A further comprises cross-pieces 12, upon which are mounted other sheave-wheels 13 for cables 5. 25 designates the said annular elevating wheel, of trough section. It is supported and guided in rotation by grooved carrying-rollers 19 mounted on shafts 21 mounted in be'arfifgs in frame B (in the construction shown in Fig. 1) and in frame A (in the construction shown in Fig. 7). These carrying-rollers 19 are free to slide longitudinally upon their shafts, for reasons hereinafter explained. The elevating wheel 25 is rotated by means of a gear 26, carried by it, and by a pinion 20 mounted on one of the shafts 21; which shaft and pinion are arranged to be rotated by suitable means, as for example a sprocket chain 22 engaging a sprocket wheel 23 on said shaft and driven by a motor 23 on truck 1. Wheel 25 is provided with internal partitions or buckets 37; and to permit adjustment of the point at which the material carried up by these buckets is discharged upon the conveyer, each bucket is provided with a hinged section 38, pivoted at 38, and arranged to be adjustably locked in various difierent angular positions by means ofsliding locking-bolts 39 adapted to enter one or another of corresponding locking-holes 40 in the side of the wheel; (see Fig. 4).

In order that the coke or other material, as pulled out from the oven or furnace, may enter the trough of wheel 25, I- provide the inclined apron 41, the outer portion of which should be at approximately the height of the sill of the oven-door; said apron being inclined so as to deliver the material into the trough of wheel 25 at or near the bottom of the wheel. This apron is supported by brackets 42 (Fig. 1). In order to permit the easy introduction into the trough of the wheel of material which may miss the apron 41 or fall from the sides thereof, I provide in the sides of wheel 25 inwardly-opening traps or doors, 27, 27, and 28 and 28, of which one set, 27 and 27 is to be used when the wheel rotates in one direction, and the other set, 28 and 28, is to be used when the wheel rotates in the opposite direction; and I further provide troughs 35, at the sides of wheel 25, into which troughs the material missing or escaping from the apron 41 may be shoveled or otherwise introduced, and from which said material will slide into wheel 25 through the doorways in the sides of the wheel when the doors, 27 and 27, or 28 and 28, are opened opposite the ends of said troughs, as presently described.

Doors or traps 27, 27, 28 and 28 are held closed normally by leaf springs 30 (Fig. 5) engaging pins 31 extending from said doors or traps through arc-shaped slots in the front of the wheel 25. When the doors 27 and 27 or 28 and 28, (according to the direction of rotation), come opposite the corresponding trough 35, lugs 32 carried by,

these doors engage cams 33 carried by arms 34 secured to the framework, and are forced inward, so opening said doors momentarily and permitting material which has accumulated on the trough 35 to slide therefrom into the wheel 25. In practice only one cam 33' is in operative position at any one time, and when the direction of rotation of Wheel 25 is to be changed the cam 33 is shifted to the other side of the frame-work; and correspondingly, only one set of doors, 27 27, or 28, 28, is provided with lugs 32 at any one time. As soon as adoor has passed the end of the corresponding trough 35 its lug 32 slips off from the cam 33 and the door is closed by its spring 30. That set of doors which are not to open are held closed by rods 36, Fig. 4, seated at their ends in holes in the front and rear of wheel 25.

The secondary frame, B, is provided to permit good adjustment of the position of the wheel 25 and apron 41 with respect to the door of the oven or furnace. Such adjustment is effected by moving frame B for ward or back, with reference to frame A, by screw 24 (Fig. 1). But in some cases provision for such close adjustment may be considered unnecessary; in which case the secondary frame B is omitted, as shown in Fig. 7. The framework is somewhat wider than the elevating wheel 25, to permit adjustment of said wheel toward and from the oven; for which reason, also, carrying rollers 19 are free to slide on their shafts 21; and to so adjust the wheel I provide a pivoted lever 43 (Fig. 6) having at its end nearest wheel 25 a slot' 44 in which works a pin of a collar 45 seated in a groove in the hub of the adjacent carrying roller 19. When. wheel 25 is rotating it is an easy matter to move wheel 25 1 1 toward or from the oven by means of this lever 43.

The rake, 48, which is adapted to enter the oven or furnace and then move backward,

drawing with it the coke or other material I be of usual construction, and may be operated by usual mechanism, and requires no detail description here. The delivery conveyer, 49, which is an ordinary link conveyer, is supported at its receiving end upon frame-member 50, as shown par ticularly in Fig. 1, and is supported at its outer end by the cables 5 and counterweights 5 secured to said cables. By means of these cables and counterweights the outer end of the conveyer may be raised or low ered through a considerable distance, so permitting the height of delivery to be varied considerably. This conveyer, and also the rake48, pass ter of wheel 25, as indicated particularly in Figs. 1 and 3; which is the prime reason why said wheel 25 is an annulus, rather than a spoked wheel. Passing the rake directly through the open center of the wheel 25 therein, may

directly through the open,cen'

' provide side makes it particularly easy for said rake to pull back the coke, etc. directly into the apron 41 and said wheel. The conveyer 49 being directly beneath that part of wheel 25 at which the material is discharged, the ma terial of necessity falls directly on the conveyer. To prevent the material from'falling oil from the conveyer, so far as possible, I

and springs 47 which hold the wings in proper position, normally, and at the same time prevent blocking of the mechanism in case a piece of coke should become stuck between the side of the conveyor and wheel 25.

The operation of the machine is as follows: The machine being opposite a suitable oven or furnace and the wheel 25 and conveyer 49 being in operation, the rake 48 is moved into the furnace and is then drawn out again, in the ordinary manner, and as it moves out it draws with it coke or other material within the furnace, causing such coke or other material to fall upon apron 41 and to slide into wheel 25. Such material is then carried up ward by wheel 25 in its rotation, owing to the troughshape of the wheel and its buckets or partitions 37; and as the material reaches a position over the conveyor 49 it falls upon the conveyer, (the particular point of such discharge being regulated by regulating the angle of the hinged sections 38 of partitions 37), and is carried oll by said conveyor and discharged. Coke or the like which drops from or around the machine is shoveled into the proper trough 35, and as wheel 25 rotates, the doors 27 and 27, or 28 and 28, open automatically when opposite said trough 35, permitting the material on said trough to slide into Wheel 25; after which said doors close.

The hinged sections 38 of buckets or partitions 37 not only permit regulation of the point at which discharge of the material from wheel 25 upon the conveyer takes place, but makes easy adjustment of the wheel 25 for rotation in the opposite direction, by reversing the angle of the sections 38. In Fig. 4 I indicate in dotted lines such reversed position of one of the sections 38.
