COKE-EXTRACTOR.

SPECIFICATION forming part of Letters Patent No. 768,067, dated August 23, 1904.

. Application. filed March 20, 1904. Serial No. 200,543. (No model.) I

`ing it out of a door on the opposite side of the oven or else by carrying it out of the door, through which the toolY or shovel is inserted by the withdrawal of the same.

It relates particularly to that class of machinery in which thetool whichremoves the coke from the oven is carried upon a carriage moving on a track 1n front of a series of ovens, and which carriage by means of appropriate mechanism is caused to travel in front of the ovens. and by further appropriate mechanism to insert and withdraw the tool and so move it horizontally and vertically that all parts of the oven in succession will be subjected to its effect.

Heretofore various machines have been invented for producing the above-indicated objects; but mostof them have been so expensive in working and so complicated in their respective parts that they have not been found in practice satisfactory; and the ultimate objectv of my invention is to construct a simply automatically operating machine possessing all of the above-indicated features, which will be simpler and less liable to get out of order.

The invention will be best understood by reference to the accompanying five sheets of drawings, forminga part of this specification, in which Figure 1 vis a plan View of the machine. Fig. 2 is a vertical elevation of the machine as seen from the right-hand side of Fig. 1. Fig. .3 is a vertical end view of the machine. Fig. 4 is a vertical cross-section of the machine onthe lines 4 4, Fig. 1; and Fig. 5 is a verticalcross-section of the machine in the other direction on the lines 5 5, Fig. 1. Fig. 6 is a sectional view on the lines 6 6, Fig. 5.

Similar characters refer to similar parts throughout the several views.

In therdrawings, A' represents the bedplate, which is made rectangular in form, as shown in Figs. 1 and 4. This is mounted upon 'four pedestals T, which in turn arev mounted upon four wheels W on axles C.

S representsthe rails upon which the extractor moves, placed in front of the series of furnaces upon the ties X X.

B is the bar or ram of the coke-removing tool, attached to which at one end isa scoop or shovel E by means of the angle-irons 1 1 and bolted to the bar B by the bolts 2 2, as

shown in Figs. 1, 3, and 4. The ram B is mounted upon a horizontally-rotating ramcarriage D, which consists of a solid casting and which is best shown by reference to Figs.

1, 2, and 3. This terminates at either end in two extension-pieces 3 3, Fig. 2, to which are bolted at either end the uprights 4 4, attached by the bolts 5 5, on which they may be raised and lowered, and thus adjusted. The uprights 4 4 are forked at the base, as shown in Figs. 2 3, and 5, and in the forks are placed rollers `6 6, two at either end` upon which the ramcarriage rotates upon the upper surface of the bed-plate A, as shown in Figs 2, 3, and 5. The ram B is arranged to slide in the ram-carriage D, between, on aseries of six, vertical rollers 7, which rotate on bearingboxes inserted in the top and bottom plates.A 8 8 of the ram-carriage D, as shown in Figs.

1, 3, 4, and 5. The position of the rollers 7 in the walls of the ram-carriage may be shifted from time to time by means of the sliding boxes 9, which are controlledby the screws 10, by moving the boxes laterally in and out,

thus. adjusting the position ofl the ram in the carriage. The ram is supported underneath at either .end by two horizontal rollers12 l2,

(shown in Fig. 4,) which aresupport'ed in the extension-pieces 3 3,' and is held in place on top by two rollers 11 11, also at either end, placed on top of it.. The front roller 11 is supported upon spring-bearings 14 at either end, lheld between a plate 13, extending outward from the-extensionpieees 3, of which it is a part, as shown in Figs. 1 and 3, and a plate 15 by the uprights 16, the object of this construction being' to prevent the mechanism from breaking in the event of the scoop E of the ram B hitting any object `which causes it to spring up quickly. The ram-carriage D is provided at its base with the flanged sleeve 19, formed integrally with the bottom plate 8, 4and is arranged to rotate on the sleeve 18, formed in a solid piece with the bed-plate. The sleeve 18 carries also four horizontal webs or arms 20, in which are held two rollers 21 21, similar to the rollers 11, which further serve to support the-ram B. On one side of the ram B is formed a tooth-rack, as shown in Figs. 1', 3, and 4, provided with the teeth 22. The mechanism which drives the ram B in and vout of the ovens consists of a shaft N, which carries at its top a spur-wheel 23, keyed thereto by the key 24, which engages with the teeth upon the toothrack upon the ram. Shaft N rotates in a bushing 17, within the bearing 18,'as shown in Fig-15, and is surrounded at its lower end by asleeve 41, which is keyed to it, which sleeve is provided at its lower end with jaws 42, which are arranged to mesh into the jaws of the clutch 29. Shaft N is solid throughout its length. The rackpinion 23 and the sleeve 41, which has jaws 42 on its lower end, are keyed to shaft N. The engine-driven'pinion 57 drives the gearwheel `39, which revolves loosely on the sleeve 41. The gear-'wheel 39 is provided with interior jaws on the lower part of its hub, which are always in engagement with corresponding jaws in the clutch 29. The clutch 29 revolves loosely on the shaft N. Vhen it is desired to drive the rain B back and forward by means of its rack 22 and pinion 23, the clutch is thrown upward by forked lever 32 engaging pins in the loose ring 31 in the clutch 29. Theupper jaws of the clutch 29 engage jaws 42 .in thel keyed sleeve 41, and also the interior jaws of the gear-wheel 39. The motion of the gear-Wheel 39 is at once transferred to the shaft N ,the pinion 23, and the rack 22, and the ram is driven as desired.

When it becomes necessary to move the machine from one oven to another, the clutch 29 is thrown downward, and its lower jaws engage with jaws on the worm-collar 28, loosely rotating on the shaft N. As the upper jaws of the clutch 29 are still in engagement with the interior-jaws on the gear-wheel 39, the movement of-that wheel Ais imparted to the worm 27, which turns the worm-wheelv 26, keyed to the shaft C of wheels WV.

1n order to move the ram D in and out of the oven, as well as to move the extractor from one oven to another, two engines F and F are employed, placed one above and the other below the bed-plate A, .as shown in Figa-2 and 3. -The piston-rod 50 of the engine F-Aterminates inl thev cross-head 51, as

shown in Fig. 1, which slides between the parallel ljiearings 52, as shown in Figs. l and 3. The cross-head 51 is attached to a connecting-rod 53, the other end of which is cecentrically coupled to the upper of the two disks 54 and 55, Figs. 1, 3, and which are connected by a shaft 56, as shown in Fig. 5, rotating in suitable bearings in the bed-plate A and carrying a'j'iinion-wheel 57, which engages with the pinion 39, which continues to rotate while the engine is being operated in a given direction. The lower engine F is conpled in precisely the same way to the disk on the lower end of the shaft 56 by means of the connecting-rod 58, terminating in a crosshead similar to the cross-head 51 and sliding between the bearings 59, as shown in Fig. 3, which bearings are similar to the bearings 52, and the cross-head being in turn connected with the piston-rod 6() of the engine F', as shown in Fig. 3. The connecting- rods 53 and 58 are so connected with the disks 54 and 55 that both engines will rotate the gear-wheel 39 in the same direction, and hence its movement will depend upon the manner of the admission of the impelling medium to the two engines. The valve-controlling` gear, which controls the ingress and egress of the impelling medium to the two engines, is shown in Figs. 1 and 3, and consists of the valve-rods 61 and 62 sliding in the valve-chests, which are connected with sliding' cross-heads 63 and 64, sliding in the bearings 65 and 66 on the outside of the bearings 52 and 59, respectively, which are actuated by the conneetingrods 67 and 68, which are attached to eccentric couplings 69 and 70 on the pin 71 and 72, which attach connecting- rods 53 and 58 to the disks 54 and 55. Any other mechanism for actuating the valves ofthe engines may be employed without reference to particular construction, as the saine is no part of the essence of the present invention.

For the purpose of moving the carriage l) upon the table A around the sleeve 18, on which it turns, a screw-lever is provided passing through a suitable bearing74, placed upon the rear end of the carriage l) and supported by a suitable bearing 75 on a bracket 76 upon the bed-plate, as shown in Figs. 1 and The kouter end` of this rod 73 is provided with a hand-wheel H, by turning which the rod revolves, and the screw-thread on the other end of it rotating in an appropriate thread in a block pivoted in the bearing 74 causes the carriage D to turn upon the sleeve 18.

For the purpose of controlling the admission of impelling medium to the engines F and F/ avalve-chamber 77 is provided, into which the supply-pipe 78 enters, as shown in Fig. 1. From this chamber, pipe 79 and 8O conduct the impelling medium to the two engines, and by means of the lever 81 the direction of the impelling medium in the chamber 77 may be IOO llO

from the gear-wheel-39 to the shaft N, iirst, forthe purpose of moving the arm B, and, second, ,for the purpose of moving the coke-extractor onthe track by means of a clutch 29,1

the direction of the movement impartedy to the wheel 39. The two iianges 30 are formed on the clutch, as shown in Figs. 5 and 7, and in them is placed a ring 31, which ring is actuated by a forked lever 32 engaging therewith, as shown. The .clutch can revolve loosely in the ring,`and by lraising .the .lever the ring and the clutch will be moved up and down. Onthe shaft below the clutch, rotatingin bear ing,35,.is a hollow sleeve 28, carrying a wormgear 27, whichy is arranged to engage with a gear-wheel 26 on the forward axle C of the carriage. a bearing in a strrup composed of two arms `33, attached tothe lower surface of the bedplate A, as shown in Figs. 3 and 4. in which the shaft rotates on the collar 35. The sleeve 28 runs loose upon the shaft N, and whenthe clutch 29 is thrown down the jaws become locked and the movement ofwheel '39 is 4imparted to the sleeve 28. The clutch 29 is raised and lowered by. means of the lever 82, as shown in Figs. 1 and 2, and by throwing the lever forward or backward the clutch 29 is alternately caused to engage with the sleeve 28 or the collar 41.

The method of operation is as follows: When it is desired to move the extractor` from one operation to the other, the lever 82 is drawnr forward, whereupon the clutch 29 engages with .the sleeve 28. The lever 81 is then moved, and impelling mediumbeing admitted to the engines causes the Aextractor to move in the direction desired, whereupon the pinion 39 will begin to rotate. The lever 82 is thrown forward, causing the clutch 29 to engage with the sleeve 28, thus causing the motion of the pinion 39 to be imparted through the clutch to the sleeve 28. This in turn will impart, its motion to the gear-wheel 26, which in turn, through the sprocket-wheels 83 83 and chain 84, will impart motion to the other The worm-gear 28 is supported inv 'shaft N to rotate and impart its movement to:

the ram B, thereby causing the same to movev in and out of the furnace. By turning the wheel H the angularity of the ram .with re-` .spect to the extractor may be changed any desired angle to dra'w the coke from the jambs of the furnace. I
