-TRANSFERRING APPARATUS FOR COAL.

' SPECIFICATION forming part of Letters. Patent No. 544,103, dated August 6, 1895.

- Application filed December 27, 1890. SerialNo. 376,159. on infidel.)

To all whom it may concern:

Be it known that we, EDWARD LINDSLEY and CHARLES E. LINDSLEY, citizens of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful .Improvements in Transferring Apparatus, of which the following is a full, clear, and'exact de- Lscriptionythat will enable others skilled in IO the art to which our invention pertains to make and use the same.

Our invention relates to apparatus for transferring coarse bulk materialsuch as coal, lime, ore,'stone, &;c.from one receptacle to another, the discharging-receptacle being at a higher level than the receiving-receptacle. Its object is to transfer material from a higher to a lower level by a system'of chutes, conduits, or conductors, in which shall normally be maintained a solid column of the material, the speed or flow of which through the system shallbe regulated by suitable appliances to discharge, as desired, and

to prevent breakage or disintegration of the -material through falling too rapidly from the higher to the lower level,- and to reduce the cost or expense of transferring material from one receptacle to another to a lower figure than is possibly attainable by means of any apparatus at presentin common use.

It consists of aseries of hoppers and chutes, conduits, or conductors with controllingvalves at the lower or discharge end and va- I rious appliances or mechanisms. to aid in horizontally to the center orhatchways of the vessel and have su-fficient inclination or natural angle for the'material to slide upon.

4321;} this particular application the vessel must be loaded from cars on a trackat the side; but other forms of. vessel than the lake or sea going carrier here illustrated-such, for instance, as canal-boats or fiat scows without inasts or high upper works-might admitofthe receiving-hopper being placed directly over the vessel and discharging therein through a-vertica'l pipe only, thus dispensing with the inclined chute or other equivalent means of moving the coal horizontally to a point over the vessel.

Ourinventionisdosigned chiefiyto meetthe requirements of the coal-trade, where transshipments from land tewater conveyances bypresent means are slowand expensive, and, owing to the rough handling in the process by which the lumps are cracked or broken and much slack created, the coal is greatly lessened in value.

By means of our apparatus we can handle larger quantities of mat'erialand do itmore expeditiously than has ever before'been done, and at the same'timeby maintaining it in solid colu nm in the conductors can let it down to the discharge-level so gently that no appreciable breakage will occur, no matter how great the fall may be.

Of course the apparatus 'willadvantageouslyhandle other materials than coal, for

ing of vessels such as are commonly employed 'in'the traffic of the great lakes from railway coal-cars now commonly used by the northern railways of'the country in the best form and arrangement of details now known to us for this particular adaptation; but obviously many changes within the skill'of a good mechanie'might be'made in the arrangement of details, and some of the parts used without others, and in relations difiering from those shown. in the drawings, without departing from the spirit of our invention as set forth in the claims at the end of this specification.

Fig. 11 is a vertical transverse section through the jib, carriage, and conduit on the line 11 11 of Fig. 1. Fig.12 isatransverse section through the conduit-joint on the line 12 12 of Fig. 4:. Figs. 13 and 14 are similar sections on the lines 13 13 and 14 14, respectively, of Fig. 4.

\Ve have preferred to show ourpresent improvements as adapted to and Working in combination with a car-dumping or transferring apparatus covered by Letters Patent No. 418,525, granted to us December 31, 1889. In this apparatus a gondola or coal-car loaded with coal or other material of like nature is run into a cylindrical cage, then raised until the load is brought close to the roof of the cage, when the car is securely clamped in position and the cage rotated on its longitudinal axis, inverting the car and its load. The roof of the cage which then sustains the load is provided with movable shutters, which are withdrawn from beneath the load and allow it to fall into any suitable receptacle placed in position to receive it. This receptacle we originally contemplated was to consist of a series of buckets the aggregate capacity of which should be equal to the capacity of the maximum car, so that the entire car-load would be receptacled at a single discharge. These buckets when filled were to be withdrawn from under the cage and empty ones substituted for them,the filled buckets being taken away and emptied by any suitable In loading vessels the filled buckets would be hoisted and swung by cranes or derricks to a position over the hatches of the vesscl, where they would be dumped or dis charged from the deck into the hold.

The breakage of the lumps of coal due to the long unrestrained fall into the hold and its violent contact with the bottom of the vesscl or other coal therein is tremendous, with aconsequent deterioration in the value of the coal. Of course the buckets might be, and

sometimes are, lowered through the hatches and their contentsdumped gently at the bottom of the vessel or on top of the pile already therein, thus saving the coal from breakage;

'but this operation consumes so much time that it is almostimpracticable andseldom resorted to. Then again we find that our cardumping apparatus will get the coal out of the cars and into the buckets much more rapidly than the buckets can be removed and replaced by empty ones, and that an enormous number of buckets is necessary to form an equipment equal to the discharging capacity of the dumping apparatus, which it is estimated wili discharge a thirty-ton car'load every three or four minutes.

By means of our present improvements we are able to remove the coal from the receiving-hopper of the dumping machine and transfer it to the hold of a vessel as rapidly as it can be placed in said hopper, and in accomplishing this to handle the coal so gently that it will have no great unimpeded fall and be subjected to nodestructive jars or shocks.

The car-dumping cylinder or cage A, is

mounted on bearing-rolls a, supported by a suitable frame and trestle work A rising from the dock B at the water side. The trackapproaches. to this trestle may be by inclines or such other means as may seem best adapted to the circumstances and conditions of each plant.

A stationar hopper C of suitable dimensions to catch the entire load of a car is located immediately beneath the cage A and is suitably attached to and supported by the trestle. This hopper inclines outwardly, as seen in Fig. 3, so that its discharge-mouth c is near the vertical dock-line, and its sides converge as they approach the mouth, so that the hopper is greatly contracted at its lower.

end. Immediately below this fixed hopper is a movable hopper D, supported bya carriage E, which is arranged to travel in orout on the side rails of jib F, which overhangs the vessel A as shown in Figs. 1 and 3. The space between the jib-railsff is entirely clear or free from all obstructions from end to end, so that the hopper D and its attachments may play back and forth between them without hinderance. At the ends they are connected by a crossbar) and at suitable intervals along their-overhanging portions by yokesf f which cross from side to side in a plane above the carriage and have depending legs that are attached to the rails.

The jib may be supported in any suitable manner from the trestle; but we prefer to carry it on a supplementary frame consisting offour posts G, resting upon the trestle or the ground itself, if desired, and connected at their tops by cross-braces and lateral bars with such diagonal or other bracing as may be necessary to give it sufiicient rigidity. \Vc prefer to make each of these posts or columns of four angle-irons placed back to back, as shown; but we do not consider any particular forms or materials of which the parts may be made as essential to our invention. The jib-rails are securely bolted to these columns by suitable brackets, such as G. (Shown in Figs. 7, 8, and 9.) At a point near the vertical dock-line the jib-rails are hinged at G to permit the outer overhanging portion of the jib to be folded up against the framework and leave a clear space outside or the vertical plane of the dock-line, so that there may be no projections to become entangled with the standing rigging or other portions of vessels lying at or approaching the dock.

The form of hinge we at present prefer to use at these points is shown in Figs. 6, 7, 8, and 9, in which it will be observed the pivotal center of the hinge is on the line of the tops of the teeth of gear-racks F, located on each rail of .the. jib, fora purpose presently to be explained. The overhanging. end of the jib is supported by guy-rods g, extending from the top of the supplementary frame G, these rods being jointed near their centers to permit of folding of the jib back upon the frame, and provided with turnbuckles to adjust their length to a nice-ty.

At the back or inside of the trestle and frame the rails f also project a sufficient distance to permit of the carriage being drawn back entirely within thedock-line, and these projecting portions are also trussed by guyrods 9' 9 extending from the frame and trestle, as shown. The jib may be raised and folded back upon the frame and trestle by any suitable means. In the drawings we have shown hoisting ropes or cables F extending from the outer corners of the jib over guide-sheaves -g g on the top of the frame G and down to the winding-drum of a.winch G located at any convenient and accessible point on the frame or trestle. V

The carriage E preferably consists of two side bars, each composed of two longitudinal channel-bars e, placed back to back and sufficiently far apart to permit of the carryingwheels E standing between them. These wheels are mounted on axles having their hearings in frame-castings e, secured to the under side of the bars 6. The side bars of the carriage are united by cross-bars E placed at suitable distances apart. V

In order to move the carriage we have pro-. vided geared racks F on each rail of the jib and mount a shaft E in bearings on the carriage, having pinions e which gear into the racks. By means of a wheel E on the shaftit may be revolved by hand direct or through a chain c.

The hopper D at its top extends from oneside to the other of the carriage and is of sufficient length to permit of the carriage movin g back and forth to any desired extent with- .out the hopper passing from beneath the discharge-opening of the fixed hopper C. By this arrangement the discharge end of the conduitmay be'moved back and forth in a vessel as far asthe length. of the hatches a will persegments,

mit forthe purpose of distributing or trimmihg the cargo as it is placed in the hold, while the hopper D, being always beneath the hopper C, may be constantly fed therefrom and the operation made continuous.

The sides and back of the hopper slope toward the contracted discharge-throat d at its lower end, and the front slopes back and merges into the throat by an easy curve 01', which prevents any tendency of the passing material to clog or choke at this point. From the throat d of the hopper an inclined chute or conduit H extends outwardly as far beyond.the dock-line as it may be necessary to move the material to bring it over the point where it is to be finally deposited;

At the point 71., near the throat of the hopper, the chute is hinged to permit of its outer end being raised wen placed into or withdrawn from the hold of a vessel.

The hinge pivot is placed at the bottom of the chute, so that its lower surface is practically continuous, while the top and sides of the lower section lay outside of those of the upper section, slipping over them when the end of the lower section is raised.

The dividing-line h between the two sections stands at an angle that will permit the top of the outer section to ride over theinner one, as will be understood from an inspection of the drawings.

At its lower end the chute H connects by an elbow I with a vertical pipe or conductor J, which reaches down into the hold of the vessel to about the level at which thematerial is finally to be deposited. This pipe consists of several telescoping-sections j jfi, which admit of adjusting its length when desired.

Upon the elbow are mounted bearing-standards M, which support a cross-shaft 2", having at each of its ends, outside of the bearings, winding-drums F, from which lifting-chains 11 extend to the lower sections 7' of the telescopicpipe. A worm-wheel i keyed on the shaft, is engaged by a screwworm 2' to turn;

the drums and raise or lower the sections, the

shaft 2' and hand-crank i of the worm being within easy access of an operator on the platforms around the elbow. Securely attached to the lower end of the lower section j is a heavy cast ring K, having formed upon it an annular worm-gear k and ledge 70-. Below this lower section is an elbow-joint of pipe L, having at its upper end an annular ring L, which slips over the ring K and embraces the ledge k thereon by its flange Z and abutment Z. This elbow is intended to turn freely on the lower'section, so as to point the discharge in any direction, and in order to lessen the friction of the joint and prevent any cramping two rows of antifriction-balls l are interposed between the ledge 70' and the opposing surfaces of the ring-L, as clearly shown in Figs. t and 5. The ring L should be made in as many as desired, and bolted together.

A bracket L mounted on the elbow carries in suitable bearings a shaft Z upon which is keyed a screw-worm l meshing into the teeth of the wheel k. This worm locks the elbow in position or revolves it when desired by the operator turning the hand-crank Z on the worm-shaft.

The elbow extends through an arc of about sixty degrees, and its discharge-orifice stands at an angle of about thirty degrees, so that it offers no obstruction to the flow of the material, but merely governs the direction of the.

discharge. In order to control or check the flow we use another elbow M, similar to elbow L, to the lower end of which it is connected by a joint similar to that between the elbow L and lower section j of the telescopic tube.

A heavy cast ring L is secured to the lower end of the elbow L, and has a ledge Z which is embraced by the flange and abutment m m of a ring M, secured to the lower elbow M, rows of balls m being placed at either side of the ledge to lessen friction, as before described. The ring M has cast upon it a worm-gear rack m into which a worm m meshes. This worm is keyed onto a shaft m mounted in suitable hearings in the bracket L on the upper elbow, and is operated by a hand-crank m to turn the elbow M to any desired position. As shown in the drawings, the discharge-orifice of this elbow is pointing down and offering the least obstruction to the flow of material through it.

The direction of the discharge may be governed tosome extent and the flow absolutely controlled or checked bythis elbow, by revolving it and raising the discharge-orifice to any desired point up to that shown by dotted lines in Fig. 4, where it would be an absolute check to and stop the flow. By means of this elbow we can control the flow without contracting the opening. Other devicessuch as valves of various patterns-might advantageously be employed at this point to check the flow, or the lower elbow, or may be both elbows L and M, might be dispensed with and the discharge-orifice of the pipe held in such close proximity-to the pile of material which has already passed through it as to sufficiently check the flow and prevent the injurious shock to the material; but at this time we prefer to use the devices shown in the drawings.

In order to raise or lower the outer end of the chute H and the telescopic down-spout attached to it, we employ hoisting ropes or cables N, which extend from the end of the chute to the carriage, and may be wound or drawn up in any desired and convenient manner. In the drawings we have shown them as fastened at one end to the outerend of the carriage and thence passing down to and around guidesheaves n, loosely mounted on the cross-shaft t" on the elbow I, thence up to and around guide-sheaves n on a crossshaft n onlthe carriage, and thence to the winding-drums o of a winch O, mounted on a platform F located beneath the outer end of the chute. These drums are mounted on a shaft 0', carried in bearing-brackets from a base-plate 0, attached to the under side of the chute. driven by a pinion 0 on one end of a shaft 0, having at its other end a worm-wheel 0 which is driven by a worm 0 on a shaft 0 suitably squared at both ends to receive hand-cranks 0 by which it may be turned.

We deem it desirable to hinge the vertical tube to the chute at the meeting-point in order to facilitate getting it into or out of a vessel and possibly also to aid in trimming, the load being deposited therein by swinging the lower end of the vertical tube back and forth independently of the motion of the carriage on the jibrails. The upper elbow is therefore composed of two segmental sections I and P, the latter beingformed on the lower end of the chute H and fitting inside of the section I, which forms the head of the vertical tube J.

The inner section P of the elbow is wider at bottom than it is at top to provide space at each side between it and the outer section for strong cast-metal frames 1), which brace the section firmly and extend far enough below it to be mounted upon the pivot-pin Q, as clearly shown in Figs. 4 and 12. At the top edge of these frames are formed worm-gear racks 19 which are engaged by screw-worms mounted on the outer section. The outer section is also provided at each side with strong cast-metal frames R, which are connected by a cross-bar R beneath the section, this bar being bolted at its ends to flanges on the side frames and provided with depending lugs or standards 0", which are mounted upon the pivot-pin Q. (See Figs.4and 12.) Cross bars R and R also connect the side frames on the outer curve of elbow-section, the upper bar It being formed with bearing-boxes for the shaft 2' of the telescoping lifting-worm i and also for two shafts 1J8, which carry the worms P engaging the racks on the inner elbow-sections. These shafts may each be provided with a hand-crank p, but we prefer to so connect them that they shall work togather and act uniformly in drawing the outer section of the elbow over the inner one and thereby swinging the lower end of the vertical tube out of the perpendicular. For this purpose we provide a crank for one shaft only and mount a sprocket-wheel S upon each shaft and connect them by a chain s, so that they will move together. Bevel-gearing and a counter shaft might be employed to efiect this purpose and in some instances might be preferred to the sprocket-wheels and chain. Under the arrangement shown the lower tube may be swung either way through an arc of about thirty degrees and held by the worms P in any position.

\Vhen the angle of the inclined chute is not very steep, and at points in the conduit where there are turns or changes of direction, it is possible, and it sometimes happens, that the material will become wedged and choke the A bevel-wheel 0 on the shaft is too chute or conduit and stop the flow therein. These stoppages are most likely to occur, in the apparatus shown in the drawings, at the bottom or throat of the hopper D and at or near the elbow at the top of the vertical ,tube. To break such a jam and start the material moving again requiresa slight agitation, and We have thought of several devices which might be employed for this purpose.

One form, shown in Fig. 6 near the throat 'of the hopper, consists of a shaft T, mounted in bearings beneath the backor lower side of -the hopper and provided with one or more on the end of the shaft and standing up near the side of the chute, where it may be reached by a man on the top of the chute.

Another form of agitator is shown mounted on the top of the chute near the elbow, and it consists of a shaft U, having a number of spiders or drag-wheels U on it, the spurs of these wheels playing through slots in the top of the chute. The spurs are so spaced that one is just about to enter the chute as the other leaves it, so that when at rest none of the spurs stand into the chute to form an obstruction. This drag-wheel shaft is provided at one end with a hand-wheel U, which may be reached by the operator on the winch-platform F under and extending out from the sides of the chute; Yet another form of agitator is shown beneath the elbow, andconsists of a shaft V, mounted in .lugs '1), depending from the side frames p of the inner section of elbow. There may be one or more arms V on this shaft, each connected to a finger or.

push-bar v, which projects through a hole'in the side of the tube. The shaft may be rocked and the fingers forced through the holes and nto the clogged mass of materia by means of a hand-lever V attached to the shaft and standing within easy reach of the operator on the platform.

Instead of any of these several devices we might have a simple'row of holes in the top of the chute, through any of which a crowbar might be thrust into the packed mass and worked to start it.

I up against the frame G. A vessel is brought alongside of the dock, with one of its hatches opposite the vertical center of the jib, which is then lowered until it stands horizontally over the hatch. The carriage, with its hopper, chute, and spouts, is'then run out on the jib and the chute and vertical conductor lowered into the vessel to the position shown in Fig. 3, with ,the exception, however, that the telescopic tube would be drawn up to its shortest length and the lower check-elbow M, with its discharge-orifice, turned up to stop the flow of any material. A car loaded with coal is then run into the cylindrical cage A, where it is raised, clamped, inverted, and the coal.

dumped, as set forth in ourPatentNo. 418,525,

before referred to, into the stationary hopper C, from whence it runs into the hopper D of the carriage. From this hopper it slides down the inclined chute H and into the Vertical pipe J, where it is checked by the elbow M. When the vertical pipe and chute are filled with a solid colnmn'of material the lower sections of the vertical pipe are slowly lowered, say, to-the position shown in the drawings. Meanwhile other cars in succession are run into the cylinder and dumped as rapidly as possible, and when the chute and vertical pipe are filled the lower elbow is turned to permit the coal to flow out of the lower end, the speed ofthe flow being regulated so that it about equals the feed of-the upperend of the system, and a full column of coal is maintained throughout the system. The movement of this column will beat such a slow rate of speed, comparatively, that the .coal will pass down from one level to another in mass and without having been subjected to any such shocks or jars as would tend to fracture the lumps and create slack. The two lower elbows at the discharge end of the pipe may be turned to guide the discharge in any direction at the pleasure of an operator stationed at that point, and the entire carriage, with its hopper, chutes, &c., movedback and forth to distribute and trim the coal as it flows into the vessel. The gradual loading of the vessel causes it to sink deeper and deeper into the water, carrying its bottom away from the lowerend of the vertical tube, and this distance may be increased, as desired, by shortening the tube itself. The operator stationed at the upper elbow I may, as directed,

raise or lower the tube through, the liftingchains 4- or move the carriage in or out by means of the hand-chain e, passing to the wheel E on the carriage, or change the angle of the vertical tube by means of the worms P and ratchet 10 in the upper elbow, or raise the entire apparatus out of the hold of the vessel by means of the winch O and hoistingropes N, as before described.
