COKE-DRAWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 435,891, dated September 2, 1890.

Application filed January 25, 1890. Serial No. 338,085- (No model.)

To all whom it may concern:

Be it known that I, NATHANIEL 0. GOLD- SMITH, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Coke-Drawing Machines, of which the following is a specification.

My invention relates to a new and improved device for drawing coke out of ovens. It comprises a driving device operated by an engine, preferably mounted upon a car which can be run back and forth in front of the oven,having an oscillating table upon which are mounted the guides for the reciprocating arm carrying the pulling-claws, with suitable mechanism for stopping, starting, tilting, and swinging the reciprocating claw-arm in a horizontal and in vertical plan es, all of which is done with power furnished by the boiler.

The description of the accompanying drawings makes a part of this specification, in which- Figure 1 is a side elevation, part of the frame being broken away to show the operating mechanism. Fig. 2 is a top plan view. Fig. 3 is a view, partly in section and partly in elevation, showing more especially that part of the mechanism which raises and lowers the rake-arm. Fig. 4 is a plan view of the same, and Fig. 5 is a side elevation of the steam and fluid cylinders of the same. Fig. (3 is an end view, partly in section, showing the rake-arnrholdin g mechanism. Figs. 7 and 8 are details of the same. Fig. 9 is an end view in opposite direction from that of Fig. 0; and Fig. 10 is a section through line a; as, Fig. 2, looking to the left. Fig. 11 is a detail view of the clutch mechanism for throwing the rake mechanism out of gear. Fig. 12 is a central vertical sectional view of the steampiston valve, showing the pistons at one-half stroke. Fig. 13 is a similar view showing the pistons at the limit of the downstroke. Fig.

5 14 is a similar view showing the pistons at the limit of their upstroke. Fig. 15 is a detail broken perspective view of the clutch mechanism for effecting the lateral swing of the rake.

The same letters and numbers on the different sheets of the drawings refer to similar parts of the mechanism.

In Fig. 1, A represents a steamboiler equipped with all necessary parts for safety and continuous working.

B represents a tank from which the boiler A is supplied.

G represents a piston steam-valve. (Shown in section, Figs. 3, 12, 13, and 14-.)

D is a steam-pipe supplying the engine E with steam from the boiler A.

E represents the engine, preferably of the three-cylinder type, bolted to the frame F. The driving mechanism of this engine is not shown, as it may be of any desired form of construction, the three-cylinder type, however,being the most compact. '7 7 represents a handle for operating the steam-valves 0f the engine E.

F represents the frame, upon which the different parts of the machine are supported, and which is mounted on wheels 13 to constitute a platform-car adapted to travel on the rails '7'.

G represents a spur-pinion, having at one end clutch-teeth, and free to revolve on the shaft K, which is the crankshaft of the engine.

II represents a clutch, which is free to slide along the shaft K, but revolves with it by means of a key or feather. On the end nearest the pinion G are clutch-teeth, which are the counterpart of those on G, by means of which the pinion Gr may be locked with the clutch II and revolve with it. On the other end of this clutch is a male part of the friction-clutcl1,whicl1 fits into the support of the chain-wheel I. This chain-wheel I is loose on the shaft K,but can be engaged and revolved by means of fl'lClLlOll-CllltCll H.

13 represents car-wheels on the axles 14,

which support the frame F and carry the same on the rails 1".

57 represents a shaft having bearings on frame F, upon which shaft are fastened the spur wheel S and the bevelpinion U.

'71. represents a transmitting-gearfastened to the shaft 4' and journaled on the bearings b. This gear 71 meshes with the pinion G and the spur-gear S, so that the shaft 57 will be revolved with shaft K. On the shaft 57 is a loose chain-wheel 18 and friction-clutch 67, which is free to slide along the shaft, but revolves with it by means of a feather let into the shaft 57. v

V represents a bevel-gear meshing with the bevel-pinion U, and keyed to the shaft 11,

which passes through turn-tables 64 and 65, and also through the horizontally-oscillating table T,'and has at its upper end a bevel-pinion W, which is fastened to it. Pinion W meshes with a bevel-gear X, which is keyed to the shaft Y, which has bearings 16 fastened to the oscillating table T. Z represents a gear keyed to shaft Y and meshing in rack 42 on rake-arm 41. On the oscillating table T is also fastened a frame 15, which supports a steam-cylinder 1 and two fluid-cylinders 2.

(See Fig.- 3.) The steam-cylinder 1 is connected to the valve 0 by means of flexible c taps the upper end of the steam-cylinder 1 and d taps the lower end of said cylinder. The upper and lower ends of 'the flu'id-cylinders 2 are connected by means of pipes 4,'in which is placed a (Shown in Figs. 1 and 5.) The steam-cylinder 1 has a piston-rod 5, the upper end of which is attached to the pistonrods 6 of the fluid-cylinder by means of the yoke 7, and on the lower end is. fastened a yoked frame 31, as shown in Fig. 3. On the piston-rod is also the piston 29, sliding in the steam-cylinderl. The piston-rods 6 have pistons sliding in the fluid-cylinders 2.

The valve O, which has a connection 38 with the boiler A, contains two pistons 37, fastened to the stem 34. These pistons 37 have ports 36, Figs. 3, 12, 13, and 14, through which the steam is free to pass.

represents exhaust-ports of the valve 0. In Fig.10, 8 represents alever keyed to the shaft 39, which has bearings 40 and 68 fastened to the frameF.

On the opposite end of the yoked arm 59 is a bevel-face, which fits the bevel-face 62 of the treadle t. The yoked arm 59 moves the friction-clutch 67 along the shaft 57 when the treadle t is pressed to the left. Between the turn-table 64, which is bolted to oscillating table T, and turn-table 65, which is fastened to the frame F, are rollers 10. (Shown in Figs. 2 and 6.) These rollers revolve on the pins 71 and support the oscillating table T at one end.

19 represents a tram-guide rail fastened to the frame F, upon which run wheels 20, revolving on axles 21, which are attached to the table T.

17 represents rubber bumpers, one of which is attached to the table T and the other to the frame. 15, (shown in Fig. 3,) which are cushions against which the yoked frame 31 strikes to limit the upward or downward movement of frame 31.

25 represents a curved rack bolted to the oscillating table T. (Shown in Fig. 2.)

23 represents a spur-wheel meshing in the rack 25 and keyed to the shaft 24, on which is also keyed a worm-wheel 22, which meshes with the worm 26, which is fastened to shaft 27, to which the chain-wheel 28 is also fastened. The shaft 24 and also shaft 27 have bearings which are attached to the frame F. (Shown in Figs. 2 and 6.) The chain-wheel 28 is connected to the chain-Wheel 18 by means of chain 72, as shown in Fig. 2.

In Fig. 6, 41 represents the rake-arm, on the upper side of which is attached a rack 42, and at one end is attached the pullingclaws by means of the bracket 49.

On the shaft Y are two frames 46, which are free tooscillate and which carry the guiderollers 47 and 48, which revolve on pins 73 and 74. These guide- rollers 47 and 48 form anti-friction journals for the rake-arm 41 and allow it to move freely back and forth. It can be swung in a Vertical plane, because the frames 46 can turn on shaft Y. These rollers are shown in section in Fig.8. To the yoked frame 31 are attached, by means of the stud 68, the frames 43.

44 and 45 represent guide-rollers, which are free to revolve on the pins 75 and 76, which are attached to the frame 43, and which IIO also allow the rake-arm 41 to move freely back and forth and to move in a vertical plane, the frames 43 and 4:6 oscillating on their respective journals. The yoked frame 31 has guides 33, (shown in Figs. 3 and 6,) which move vertically on the rods 32, which are supported by the frame 15 and the oscillating table T.

Mode of operation: By looking at Fig. 1 it will be seen that by throwing the lever L to the left the chain-wheel I will be locked to the clutch II by means of the friction-clutch faces. This will allow the operator to drive the worm Q and revolve the axle 14 by means of the worm-wheel R, and move the machine back and forth on the track 1' by means of the reversing-lever 77, which arranges the valves of the engine E so that the crank-shaft K shall revolve in either one direction or the other. I thus provide a self-propelling machine, and at the same time the worm Q locks the wheel R and keeps the machine from moving when the pressure of the rake 011 the coke would tend to move the machine on the track-rails r. If, on the contrary, he throws the handle L to the right the clutch H becomes disengaged from the chain-wheel I and is locked to the pinion G by means of the clutch-face, and when the shaft K revolves the spur-pinion G drives the transmittinggear h, which in turn drives the gear S, which revolves the shaft 57 and turns the bevelpinion U, the bevel-wheel V, the shaft 11, the bevel-pinion IV, and the bevel-wheel X, the shaft Y, and the spur-wheel Z, which moves the rake-arm 41 by means of the rack 42. This will run the rake-arm 41 into the oven; but by reversing the engine, by means of 18V61'77, the direction of the movement of the rakearm will be reversed and it will come out of the oven. By throwing the lever 8, Fig. 10, to the left the pistons 37 in the valve 0, Fig. 3, are raised. The lower valve opens the exhaust-port 35 to the lower end of the steamcylinder 1, and the upper valve opens port 36 and allows the steam to pass from the steamport 38 into the steam-pipe c, admitting the steam into the top of the steam-cylinder 1. This forces the piston-rod 5 down and forces the fluid from the bottom of the fluid-cylinders 2 through the connecting-pipet and the throttle-vale 3 into the top of the fluid-cylinders 2, the valve 3 affording the means of regulating the speed at which the piston-rod 5 travels. Inasmuch as the piston-rod 5 is attached to the yoked frame 31, it will be seen in Fig. 6 that when the pistomrod 5 is pushed down the end of the rake-arm 41, to which the pulling-claws 50 are attached, will be raised, swinging on the shaft Y. hen the lever 8, Fig. 10, is pulled to the right, (or toward the operator,) however, the pistons 37, Fig. 3, will be pulled down, and the steam from the upperend of the cylinder 1 is free to pass through the steam-pipe 0 into the exhaust-opening 35, while at the same time steam. will be admitted through the lower steam-port and the steam-pipe d into the lower end of the steamcylinder 1, raising the piston 29 and the piston-rod 5, and forcing the fluid from the top of the cylinders 2 into the bottom and lowering the pulling-claws 50,Fig. 6. This arrangement affords a means of raising the pullingclaws of the rake-arm above the coke when the rake-arm is passing into the oven, and forcing it down on the coke when the rakearm is passing out of the oven. hen it is desired to swing the rake-arm to right or left while it is being reciprocated, the foot-treadle t is moved to the left in Fig. 10, and the yoked arm 59 is thereby. moved to the right in Fig. 2, forcing the friction-clutch 67 into the chainwheel 18, and causing the same to revolve with the shaft 57. This motion of the treadle compresses the spring 58, and as soon as the treadle is released the spring forces it back into its natural position, releasing the clutch and stopping the lateral swinging movement of the rake-arm. \Vhile the treadle is pushed to the right, however, and while the shaft 57 is revolving, the chain-wheel l8 revolves the chain-wheel 28 by means of the chain 72, and turns the shaft 27 and the worm 26, the wormwheel 22, and the gear 23 by means of the shaft 24, and swings the table T to the right or to the left by means of the rack 25. It will be seen that this table rides on the wheels 20, traveling on the rail 19. (See Fig. 2.) Said table is pivoted at the opposite end by the shaft 11, and supported on the conical rollers 10,which bear on the turn-table faces 04 and and allow it to swivel freely. Inasmuch as all the guides and bearings for the rakearm 41 are attached to this oscillating table T, it will'be observed that the rake-arm can move in a horizontal plane, and by regulating the time which the foot-treadle is pressed the pulling-claw 50 can be swung from side to side in any part of the oven. This gives the operator complete control of the rake by means of the reversing-lever 77, which controls the means of moving the rake back and forth, and the lever 8, which controls the raising and lowering mechanism, and the foottreadle t, which controls the mechanism for moving the rake horizontally, and allows him to operate the rake very rapidly and easily.

In Fig. 11 is shown a modification in the mechanism for propelling the rake backward and forward. It will be noticed that, as heretofore described, the chain-wheels 18 and 2S and mechanism for oscillating table T could only be operated while the gear U, and consequently the rake, was in motion. The modification in Fig. 11 provides for the operation of chain-wheels 18 and 28 while the gear U remains idle, and is a representation of that part of shaft 57 which lies to the right of chaiirwheel 18. F represents the frame in which the shaft is mounted; 57, the shaft; U, the gear\vheel; a, a boxing secured to frame F, in which revolves a hollow sleeve m, through which passes the shaft 57. The wheel U is secured to one end of sleeve m, and to the IIO - vices substantially the same as used to operate the clutch 67, Fig. 15, is not more fully illustrated. By means of this device the gear U may be thrown into and out of engagement with the shaft 57 and the table T swung independently from the backward and forward movement of the rake.

The object of my invention is to provide a rake operated by steam-power and so arranged that the rake may have a motion in a vertical and horizontal plane and move in any position without producing any strain on the different parts of the machine which will tend to interfere with their moving freely.

In respect to the motion of the rake in and out of the oven it will be seen that the planetary system of gears, including bevel-pinion U, bevel-gear V, bevel-pinion WV, and bevelgear X, allows the gear Z on the shaft Y to always occupy a position. at right angles to the rack 42 on the rake-arm 41, and by this means there is no position in a horizontal plane limited by the motion of the table T in which the rake-arm 41 cannot be driven in and out of the oven.

I have shown the mechanism here described as adapted to be moved by the operator seated on seat 9, who manipulates the levers to get the various desired movements. As the rake has to beinserted into the oven to varying distances in the operation of pulling the coke, and as the rake is driven by steam and controlled by admitting and cutting off the steam, I avoid the use of Windlass and ropes for reciprocating the rake-arm.

I believe I am the first to provide amachine which will control the operation of the rake and the pulling device by manipulation of the levers for controlling the different rake movements vertically and horizontally as well as controlling the'length of the stroke.

The fluid-cylinders 2 are merely to regulate the speed at which the piston-rod 5 travels, either up or down, and this speed can be controlled by the opening in the throttle-valve 3, allowing a greater or less quantity of fluid to pass through it.

The steam-pipes c and d are made flexible so that the steam may always pass into the steam-cylinder 1, in whatever position the oscillating table T may occupy.

I do not confine myself to the specific con- I struction or arrangement of parts shown by the drawings. The piston steamvalve 0, the three cylinder-engines E, the desired arrangement of parts to make the machine a self-propelling one, and the arrangement of parts to move the table T back and forth in ahorizontal plane can be variously modified without interfering with the utility and successful working of the machine and still present the principal features of my invention.
