SPECIFICATION forming part of Letters Patent No. 625,086, dated-May' 16, 189,9.. Application lerl December 27, 1898. Serial No. 700,422. (No model.)

To @ZZ whom, t may con/cern:

Beit known that I, OWEN J, CONLEY, a citizen of the United States, residing at New York, in the borough of Manhattan and State of New York, have invented new and useful Improvements in Conveyers for Unloading Vessels, of which the following is a specification.

The presentimprovements relate especially to details of construction in connection with a prior invention in conveyers for unloading vessels disclosed in an application for a patent bearing Serial No. 680,242, filed by me in the United States Patent Office on the 10th day of May, 1898, in which application is shown and described a vessel provided with a carrying-compartment consisting of in-A clined decks located near the bottom of the vessel and extending approximately the full length thereof, a compartment being provided near the bow of the vessel for the location of the engine or other source of power by which the apparatus is operated, and the inclined decks joining each other in a line over the keel of the vessel, hoppers and sliding doors therefor being provided at intervals at the junction of said decks for admitting of the passage of the material to be handled upon a flexible conveyer or belt su pported by rollers directly thereunder and driven by a drum operatively connected with the engine or other source of power. said conveyer was so arranged as to convey the material to an elevator of well-known form, which in turn elevated it to a second conveyer pivotally supported upon the deck of the vessel and connected at its free or outer end with block-and-fall mechanism connected to a derrick and a winch supported upon the deck of the vessel, guy-ropes being provided at the outer end of said conveyerfor manipulating it at will.

My present improvements have for their objects, first, to provide means for simultaneously holding in check and feeding the material forward from the carryingcompartment to the lower conveyer or belt and so arranging said checking and feeding means that the independent parts thereof may be either independently or collectively easily and quickly connected to and disconnected from the source of power which drives the entire mech- The forward end of v anism or to an independent source of power,

if preferred, thereby making it possible toresecond, to so arrange the automatic feeding apparatus which controls the Iiow of the material from the carrying-compartment that it will hold different'classes or types of material in check which are known to flow or move at different angles or sl0pes-such, for instance, as bituminous, lump, steamboat, egg, stove, n ut, chestnut,and pea coal, shelled corn, wheat, and sand; third, to provide means in the nature of ledges or pockets near the bottoms of the inclined decks and extending parallel with the feeding mechanism which delivers the material to the conveyer or belt, whereby the liner portions of the material being han'- dled will in its descent lodge in said pockets in such manner that portions of the load being discharged will move thereover, thereby per'- forming the important function of preventing unnecessary wear upon the bottom of such inclined decks as will necessarily result in the handling of such material as coal and iron ore; fourth, to provide means whereby the outer or universally-pivoted conveyer located above the deck may be controlled in all of its movements by a source of power placed under the immediate control of a single attendant on board of the vessel and at such apoint as will enable him to have a clear and unobstructed view of the delivery end of said con-- veyer at all times; fifth, to' combine any and all of the before-mentioned improvements with the several generic features of the apparatus disclosed and claimed in my prior application above referred to in such a manner as to make a complete, practical, and operative mechanism adapted under all conditions' of usage to deliver material from a vessel provided with such apparatus to another lvessel or at a dock or on board of cars adjacent to such dock under all conditions of tide, wind, and weather.

The before-mentioned objects will be effected by the improvements illustrated in the accompanying drawings, and particularly de scribed in the specication which follows, reteren ce being had to the claims at the end of IOO this specification for the features of novelty embodied in said improvements.

Referring now to the drawings, in all of which like letters and numerals of reference represent like or equivalent parts wherever used, Figure lis a sectional view of the front part of a Vessel, illustratingin side elevation al View my invention as disclosed in the prior application above referred to and the several improvements upon the operative parts thereof. Fig. 2 is an enlarged plan View of the major portion of the apparatus illustratedin Fig. 1, all of that portion thereof below the deck of the vessel being shown in dotted lines. Fig. 3 is a front elevational View of the apparatus as seen looking at Fig. 2 from the right toward the left hand side of the drawings in the direction of the arrows, all of the apparatus below the deck of the vessel being illustrated also in this figure in dotted lines. Fig. 4 is a plan view of a portion of the bottom of the carrying-compartment, illustrating the double-inclined or roof-like structure, which sustains the central body of the load and guides the same in opposite directions toward the inclined bottoms, two pairs of the hoppers through which the material 'is fed being shown, the doors of one pair of said hoppers being open while the doors of the other pair opposite thereto are closed, and the means for controlling the movements of said doors illustrated in dotted lines, the beams or supporting-timbers for all of said parts being also illustrated in dotted lines. Fig. 5 is an enlarged transverse sectional view taken through that portion of the apparatus which illustrates the means of preventing the weight of the material to be handled from resting directly upon the conveyer or belt located beneath the entire load, said transverse section being taken upon the line a; fr, Fig. 4, and as seen looking in the direction of the arrows from the top toward the bottom of the drawings, the conveyer or belt, the bottoms of the hoppers, the automatic feeding mechanism, the sliding doors and controlling apparatus therefor, and their method of operation upon the material to be handled being also illustrated in this view of the drawings. Fig. 5 is an enlarged cross-sectional view of a vessel supplied with my improvement and illustrating therein the side pockets which hold portions of the material constituting the load and the operation of the feeding mechanism in such manner as to prevent the larger particles thereof from choking or bridging the openings through which the material is fed laterally to the conveyer or belt located beneath the load. Fig. 6 is a similar transverse sectional view to that illustrated in Fig. 5, but on a smaller scale, the material to be handled, however, not being shown, said view being taken on the line ,e z, Fig. et, and as seen looking from the bottom toward the top of that `figure in the drawings in the direction of the arrows, the transverse beams or timbers for the inclined bottoms of the inclined or rooflike portion which sustains the central body of the load being shown in elevational View, as are also the feeding mechanism and the controlling mechanism therefor. Fig. 7 is an enlarged part sectional part side elevational View on the broken line y g/ 'y y, Fig. 4, of a part of the bottom of the carrying-compartment of a vessel and the means for automatically feeding the material, with the additional means for regulating the fiow thereof forward from the carrying compartment through the hoppers to the lower conveyer or belt, which latter is shown partly in side elevational and partly in broken sectional View, a part of the means for sustaining and guiding said conveyer or belt being also shown in ,side elevational view, as are also the beams and timbers for supportin g the entire apparatus. Fig. S is a detail View illustrating the means for locking or securing the sliding doors in such manner as to effect a constant iow of the material to the automatically-controlled feedingmechanism. Fig. 9 is a transverse sectional view taken through the upper portion of the conveyer or belt, illustrating also in elevational view the means for preventing such conveyer or belt from swaying or swinging from side to side, together with the means for supporting the latter. Fig. l0 is a transverse sectional View illustrating both the upper and lower portions of the conveyer or belt, the means for giving to the upper portion thereof its trough-like conformation and for supporting the load to be carried thereon being shown in elevational View, together with additional means, shown also in elevational View, for supporting the lower or return portion of said conveyer or belt and the beams or timbers for sustaining all of said parts. Fig. ll is a transverse sectional view taken on the line z e", Fig. l, both parts of the conveyer or belt of the outer or pivoted conveyer being shown in sectional View, the means of giving to the upper portion of said belt a trough-like conformation and for preventing the same from swaying or swinging, together with means for supporting the return portion of the conveyeror belt, being all shown in elevational View, the outer or upper cylindrical drum for aiding in sustaining and driving said conveyer or belt being shown also in elevational View. Fig. l2 is an enlarged plan view of the means for enabling a single attendant to control the application of power to the movements of the outer or delivery end of the pivoted conveyer in all directions; and Fig. 13 is a side elevational View of a major portion of the apparatus shown in Fig. l2, which is located upon or secured directly to the deck of the vessel and as seen looking at the same from the bottom toward the top of the drawings in the direction of the arrow.

Referring now to the drawings in detail, H represents the hull of the vessel, and L the carrying-compartment, having inclined bot- IOO toms K K and inclined ends K at the opposite ends of the vessel, as shown in dotted lines in Fig. 2.

O represents a conveyer or belt made of iiexible material', preferably rubber, and of the desired width and strength to carry the material to be handled, said conveyer or belt being located, preferably, entirely beneath the longitudinal center of the load in the compartment L and supported at its opposite ends by cylindrical driving drums or rollers R and R, carried by shafting journaled in journalbearings secured to longitudinally-arranged beams or timbers N', supported by braced standards t t, resting `upon or secured to the ribs or bottoms of the vessel in such manner as to give to the structure the greatest possible strength. The upper portion of this conveyer or belt is supported at convenient distances by cylinders or drums 24 24, located directly beneath the center thereof, and angularly-arranged cylinders or drums 23 23, located under the sides thereof, as shown in Figs. 7 and l0 of the drawings, the arrangement being such as to give to the upper or carrying portion of said conveyer or belt a trough-like conformation. These cylinders or drums 24 24 23 23 are journaled upon standards which are supported in turn by cross-timbers T5 T5, secured to the longitudinal beams or timbers N' N', supported by standards t t. Secured beneath the same cross-timbers T5 T5 by downardly-extending arms and cross-shafting are additional cylinders or drums 25 25, adapted to support or guide the lower 'portion of the conveyer or belt on its return or backward movement.

22 22 (see Figs. 7 and 9) represent additional cylinders or drums secured by standards beneath cross-timbers'T4 T4, resting upon longitudinal beams or timbers N N above and parallel to the before-mentioned beams or timbers Nl N', said beams or timbers N N being also sustained by the same framework which supports the first-named beams or timbers.

It will be noticed upon examination of Fig. 7 of the drawings that the pairs of cylinders or drums 22 22, which rest against thelateral edges of the upperor carrying portion of the conveyer or belt O, are located intermediate the sets of cylinders or drums 24 2423 23, which support the conveyer or belt O and give to it its trough-like conformation, and `that the arrangement is such that as this trough-like portion of the conveyer or belt is advanced under the action of the driving mechanism both it and the load carried thereby will be prevented from swaying or swinging under abnormal conditions of movements of the vessel in rough weather'.

Referring now particularly to Figs. 4, 5, 6, and 7, M M' represent a double-inclined or roof-like structure at the center and bottom of the carrying-compartment and extending the entire length thereof, said structure being supported by a series of strong rafters T3 T2 in the same manner as the roof of a house is supported by rafters, the ends of the rafters T2 T3 resting upon iron girders T2 T6 T7, properly secured in such manner as to give to the structure sufficient strength to sustain the load resting directly upon it, similar rafters T T' being illustrated in Fig. G of the drawings for sustaining the inclined bottoms K K and those parts of the load carried thereby. This double-inclined or roof-like structure is locatedwith its lineal center or the junction of the, inclined surfaces M M' directlyv above the center of the conveyor or belt O, as clearly shown in Fig. 5 of the drawings, its function being to support` the weight of the central portion of the load in the carrying-compartment and direct the movements thereof in opposite directions toward the inclined bottoms K K.

At definite distances apart there are provided at the junction of the inclined surfaces M M' and inclined bottoms K K pairs of openings or hoppers H' H', H2 H2, H3 H3, dac., located directly opposite each other and with their lower or bottom portionsextending in- Ward in the nature of chutes, as clearly shown in Figs. 5 and 7 of the drawings, to points approaching the lateral edges of the upper or trough-like carrying portion of the conveyer or belt O.

d d d d el d represent upwardly-extendin g pyramid-like surfaces between the j unctures of the inclined surfaces 'M M' and inc-lined bottoms K K and directly intermediate lthe pairs of hoppers H' H', H2 H2, tbc., the function of said pyramidal surfaces being to afford as little friction as possible to the material and aid in its descent to the hoppers H' H', H2 H2, H3 H3, &c.

In Fig. 5 of the drawings I have shown in enlarged sectional view the manner in which the material C, illustrated therein as coarse and fine bituminous coal or iron ore, is caused to descend by gravity in opposite direc-tions upon the inclined surfaces M M' and the inclined bottoms K K, the bottoms of the hoppers H2 H2 being shown beneath the edges of the inclined surfaces M M'. In this figure of the drawings I have also illustrated lateral ledges or pockets 4 4 between the lower edges` of the inclined'bottoms K K and the bottoms of the hoppers H2 H2, H2 H3, dto., the function of said ledges or pockets being to cause the finer portions of the material Where such material as illustrated in this figure is being handled to lodge thereininsuch manner that as the larger portions of the material descend any bridging action will be prevented between the bottom of the hoppers H' H2, &c., and the lower edge of the door 3, as will be described more particularly in connection with the description of Fig. 5f of the drawings. These ledges or pockets 4 4 are located directly opposite the doors 3 3 and are of substantially the same width as'the hoppers, as shown. If preferred, the inclined bottoms K K maybe entirely done away with and vertical walls IOO TIO

5 5 substituted therefor, extending the entire length of the vessel, the junction of said vertical walls and the bottoms of the hoppers being located, as shown in Fig. 5, so that when the doors 3 3 are in their lower or closed positions they will intersect with the bottoms of said` hoppers. When so constructed, with vertical Walls 5 5 in place of the inclined bottoms K K, the spaces between said vertical Walls and the hull of the vessel H can be filled with the material to be handled, and after the load of material above the same is removed this material, if desired, can be thrown into the hoppers by hand in the usual Way, or inasmuch as it is often desirable to provide permanent ballast for vessels the same may be left permanently in position, it' preferred. When these side pockets are constructed as shown in Fig. 5, they will hold or sustain the material between the vertical Walls 5 5 and the sides and bottom of a vessel in such manner that the moving material as it passes downward through the hoppers by its own Weight will slide upon the upper surface of that portion of the material which is thus permanentlyheld in place between said Walls and the sides and bottom of the vessel. I have also illustrated in this figure of the drawings how one of the enlarged pieces or chunks of material, as C', will be fed through the hopper H2 as the apparatus is operated by reason of the fact that when the lower end of said piece or chunk comes into mechanical contact with the outer bottom edge of the hopper its upper end will be subjected to the feeding action of the feed-roll 12, as clearly illustrated, thereby causing it to be liberated and moved endwise as the large chunks are seen to be moving directlyT in front of it. With such an arrangement of parts it is possible always to feed coarse and fine material through the hoppers to the checking and feeding rolls 1l 12 and from them directly to the conveyer-belt O, and this particular feature l regard as important in connection with the handling of coarse and fine material conjointly, such as coal or iron ore. Inasmuch as these pockets 4 l hold the lowerportion of the material in check by reason of the walls 5 5 it is apparent that the moving material must slide upon the former, thereby avoid-v ing the Wear which would naturally occur to the inclined bottoms were the material allowed to slide by its own weight directly upon said bottoms, a feature of importance in that it prevents the wearing out of the sliding surface, and therefore avoids unnecessary repairs, and this feature is regardedby me as important in connection with my improvenient.

I will now describe the sliding doors 3 and their operating mechanism for regulating the iioW of material to the conveyer or belt and also the feed and controlling mechanism, which automatically feeds the material for- Ward to said conveyer or belt.

Each hopper H H2 H2, &c., is provided with a door 3, adapted to slide in grooves beneath the under side of the inclined surfaces M M', (see Fig. 7,) and to the under sides of said doors are secured a series of racks 6 6 6. 7 7 7 are pinions adapted to mesh with said racks, said pinions being carried by shafting 8, journaled in the sides of the hoppers, the exterior or exposed ends of said shafting being of rectangular shape for the application of a winch or crank-handle. On the outer end of each shaft 8 is a ratchet-'wheel 9. 10 l0 are pawls pivotally secured to the sides of the hoppers H H2 H3, dac., the free ends of said pawls being adapted to take in the ratchetteeth of the ratchet-wheels. These doors 3 are moved back and forth at will with a crankhandle or winch, as described, and are locked at any desired height by the pawls 10 10,thereby regulating the iiow of the material therethrough to the conveyer or belt.

l will now describe the mechanism for positively moving or feeding the material forward to the conveyer or belt O.

16 16 are two lines of shafting extending the entire length of the carrying-compartment and journaled in cross-timbers N2 N2, which are supported by the longitudinal beams or timbers N N. To the forward ends of these lines of shafting are secured bevel gear-Wheels ff, (see Fig. 2,) which mesh with similar bevel gear-Wheels f f', secured each to an independent shaft journaled in standards attached to the bottom of the vessel and carrying a cone-pulley 21, adapted to receive three different speeds by a belt b4 from a corresponding cone-pulley 20, secured to shafting 19, which supports the driving cylinder or drum R for the lower conveyer or belt O, said line of shafting being connected, as indicated, by a belt A and pulleys to the driving-shaft of the engine E, all as clearly illustrated in Figs. 2 and 3 of the drawings. The conepulleys 2O and 21, located on opposite sides of the conveyer or belt O, as described, are connected by driving-belts b4 b4, and variable speed is imparted to the shafting 16, as will be understood on inspection of Fig. 2 of the drawings.

Located directly beneath the inner bottoms of the hoppers H H H2 H2 H3 H3 and upon the parallel lines of shafting 16 16 are pairs of iron corrugated feeding-drums l1 11,adapt ed to run loosely upon said shafting. These corrugated feeding-drums are of slightlygreater width than the chute-like portion of the hop pers H H H2 H2 H3 H2, dac., (see Fig. 7,) and are each provided with-a clutch k and clutch-lever Z to clutch or connect it directly to its supporting-shafting 16, the arrangement being such that all of said drums are idle or stationary unless operatively connected to their proper line of shafting 16 by their corresponding clutches,said clutches being of Well-known structure.

12 12 are iron corrugated feed-regulating drums, adj ustably journaled in oblong slots or grooves-19 19 in the opposite sides of the IOD IIO

hoppers and directly above the corrugated feed-drums 1l l1,asclearlyillustrated in Figs. 5 and 7 of the drawings. These drums 12 12 are made adjustable in such oblong slots by journaling them in journal-bearings adapted to slide in the slots, and said sliding journalbearings are connected by swivels with regulating-screws 18 18, the arrangement being such that the corrugated drums may be adj usted to various heights to correspond to the well-known sliding slopes or angles of the different-size material to be handled, so that said material will not advance by gravity over the feed-drums 1l, located beneath them.

In Fig. 7 of the drawings the right-hand portion thereof illustrates in elevational view one of the feeding-drums 11 on the distant side of the conveyer or belt O, the door3 and mechanism for operating the same, the hopper H2, and the corrugated drum 12 for regulating the feed of the material C as it is fed forward to the conveyer or belt O, the drum 11 being connected by its clutch 7c to the farther line of shafting 16, while the left-hand` portion of said drawing illustrates that one of the next adjacent pair of corrugated feeding-drums l1 located on the near side of the conveyer or belt O and operatively connected to the near line of shafting 16 by its clutch mechanism, the bottom only of the hopper H2 being seen. lt is apparent, however, that the feed-regulating drum 12 is not visible in this portion of the ligure, nor can the material VC as it is fed forward to the conveyer or belt O be seen, as it is moving in a reverse direction from that illustrated in the right-hand side of said gure of the drawings.

To one end of each of the sleeves supporting the drums 11 is attached a sprocketwheel s, (see Figs. 5, 6, and 7,) and to the corresponding eud of the corrugated feed-regulatin g drum 12 is attached asimilar sprocketwheel s', 13 being a sprocket-chain connecting said sprocket-wheels together.

.95 85 are movable belt-tightening sheaves adapted to move in a vertical directionby guiding-grooves in supports,as shown, said sheaves being sustained in a well-known manner by cords l5 15, passing upward over sheaves s4 s4, thence downward under sheaves s3 s3, thence to the right and left over sheaves 3252, where they are attached to heavy weights w w, the function of said weights, cords, and sheaves being to give proper tension to the sprocket-chains 13 13 under different conditions of adjustment of the' feed-regulating drums 12 12 andtheir pairs of regulatingscrews 18 18.

In the left-hand side of Fig. 7 the sprocketchains 13 and their sprocket-wheels ss for the feed-drums l1 and regulating-drums 12, located on opposite sides of the conveyer or belt O, are shown complete in side elevational View, while on the right-hand side of this figure of the drawings the broken sectional view necessarily leaves out some of said parts. All

of these parts, however, are illustrated in detail in Fig. 6.

The elevator O', with its driving cylinders or drums E E and hopper E4, is not substantially different from that disclosed in my prior application bearing Serial No. 680,242, and is arranged, as described in that application, so as to receive the material from the delivery end of the lower conveyer or belt O in its buckets, carrying the same upward to a point above deck and discharging it in the hopper E4, where it passes from thence to the outer or pivoted conveyer, which is provided with a conveyervbelt O2, driven by cylindrical drums E2 E2, journaled in a truss or framework T, the general structure of said conveyeror belt and its controlling or operating parts being substantially like that of the lower or horizontal conveyer or belt O, the details of which have been already described.

I have illustrated in Fig. 11 of the drawings a transverse sectional View of this exterior pivoted conveyer and its supporting parts as taken on the line z' z', looking in the direction of the arrows from the left 'toward the right, Fig. l, from which it will be seen that the structure is not substantially' different from that of the lower conveyer, as already 'indicated The outer conveyer is pivotally supported in the same manner as was the like conveyer disclosed in my prior application, B being a bevel gear-wheel located on a shaft carrying pulleys P2 P2, said gear-wheel meshing with the under part of a double bevel gear-wheel B' B2, sustained by a pivot pin or bolt, (not shown,) the upper part of said gear- Wheel meshing with a third bevel gear-Wheel B2, connected directly to the supporting-shaft of the driving drum or cylinder E2 for the conveyer-belt O2. On one end of the main shafting 19 (see Fig. 2 of the drawings) is a pulley P, connected by a belt `b to a pulley P2 above deck upon the same shaft as the bevel gear-wheel B. A second pulley P3 upon this shaft is connected by a belt b2 Witha pulley P4, carried by a shaft supported by journals at a point above the deck of the vessel, and attached to the other end of this shaft is a pulley P5, connected by a belt h2 to a pulley PS, carried by the same shaft which supports the upper or driving cylinder or drum E of the elevator O. All of the driving mechanism of the elevator O and the conveyer or belt of the outer or pivoted conveyer O2, as thus described, is substantially the same as disclosed in my prior application above referred to.

The improvements in the mechanism for controlling the lnovements of the free or delivery end of the upper or pivoted conveyer will now be described, reference being had particularly to Figs. 1, 2, 3, 12, and 13..

D represents a derrick firmly secured to the deck of the vessel and of sufficient height and strength to carry at all 'times the weight of the exterior or pivoted conveyer and the load IOO IIO

carried thereby in operation, this derrick being not substantially different from the similar structure disclosed in my prior application. On the upper end of this derrick is journaled a sheavep', and at a point near the outer or free end of the pivoted conveyer is located a similar sheave p.

r is a strong rope or wire cable secured to the top of the derrick at e, passing thence around the sheave p back to the top of the derrick D over the sheave p', and thence downward to a drum W, adapted to run loosely upon a horizontal shaft 30, journaled at its opposite ends in strong standards V V, firmly secured to the deck of the vessel.'

On the shaft 30 is a sprocket-wheel operatively connected by a sprocket-chain 29 to a sprocket-Wheel upon the same shaft which supports the pulleys P'L P5, the arrangement being such that the shaft 30 is constantly driven, with the rest of the mechanism, by the sprocket-chain and sprocket-wheels referred to, the function of the rope o and the drum lV, to which it is attached, being to raise and lower the outer or free end of the pivoted conveyer.

B4 is a cross-bar of substantially the same width as the vessel and iirmly secured to the derrick D at a point about midway the height thereof, said cross-bar being additionally secured laterally bybraces G G', running to the front side of the derrick. In the outer ends of the cross-bar BL1 are secured sheaves p2 p, and at points intermediate its ends are secured additional sheaves p2 p, with their aXes located at right angles to the first-named sheaves.

g g' are strong ropes or cables secured at their outer ends at points e' c2 near the free or delivery end of the pivoted conveyer, said ropes passing, as shown, rearward around the sheaves p2 p, thence inward around the sheaves 193195, and downward to and around driving-drums W2 WV', running loosely upon the same shaft'30 which supports the driv-i ingdrum W. 1t is the function of these ropes g g' and drums W2 W', to which they are attached, to move the outer or delivery end l of the pivoted conveyer laterally.

The drums WV W' lV2 are provided with jaw-clutches 31 31 31 for positively connectp ing them directly to the shaft 30, and operating-levers J J J2 are provided for effecting such connections. It is obvious that any well-known form of friction-clutch may be substituted for the j avv-clutches, if preferred. Each of said drums is also provided with a brake-band 34C, (see Fig. 13,) operatively connected with a bell-crank lever Q and aconnecting-link U to pedals Y Y Y2, and all of said pedals and the clutch-controlling levers are located in close proximity to each other, so as to be readily accessible to the attendant who has the control or management of the pivoted or delivery conveyer. All of the pedals are provided with spring-pressed sector-shaped racks or equivalent retaining devices h for holding the drums by the brakebands 34, if desired, said retaining devices being easily released by the foot of the attendant.

The operation of the apparatus is as follows: Suppose it is desired to deliver coal to a vessel at sea and under such conditions of wind and waves as to make such delivery eX- ceedingly difficult by ordinary or well-known means of coaling from colliers. The doors 3 3 3 of the carrying-compartment L are closed, after which the vessel is loaded with the coal, tillingit (the carrying-compartment) to its fullest capacity. On arrival at the point where it is desired to deliver the coal to a vessel at sea, the vessel H is placed alongside of the vessel to be coaled, With the free end of the pivoted conveyer extending over the sides of both vessels. The engine E isset in motion, imparting movement to all of the operative parts of the apparatus, and such of the clutch-levers Z Z as it may be thought desirable to actuate are so moved as to connect their corresponding corrugated feed-drums 11 with the lines of continuously-rotating shafting 1G 16. The corresponding doors 3 3 thereto are now opened by the attendants below deck to the desired point, having first liberated the pawls 10 1O from the ratchetwheels 9, after which said pawls are restored to position, so as to lock the same. The attendant on the upper deck at the drums WV W' W2 raises the free end of lthe delivery-conveyer to the desired height by connecting the friction-clutch 31 of the drum W to the shaft 30, at the same time placing his foot upon the brake-pedal Y and releasing the clutch when the desired height is attained. The reverse movement is attained by simply allowing the weight of the free end of the conveyer to act by gravity, the speed of the descent being controlled by the brake-band 34 and pedal Y. If it is desired to move the free end of the conveyer, say, to the right, he actuates the friction-clutch lever J2, thereby connecting the drum W2 to the shaft 30 and imparting motion to the parts through the agency of the rope g. Should the weight of the conveyer tend to swing it too far, he (the attendant) has only to place his foot upon the pedal Y' of the drum WV', and thus check it. To move the free end of the conveyerin a reverse direction, he actuates the frictionclutch lever J', connecting the drum W', thereby imparting motion to the left through the agency of the rope g'. As the speed with which the drums W WV' W2 are driven is relatively high and the clutches and brakes are all under the immediate control of the attendant, he is enabled to move the free end of the conveyer with great rapidity and accuracy, thereby compensating for the rise and fall of the delivering vessel, owing to the waves and wind. 1

The operation of the feeding and controlling apparatus is as follows: The material C is fed forward by its own weight, owing to the action of the inclined surfaces M M' and inlOO IXO

clined bottoms K K, passing thence downward through the hoppers H H2 H3 H4, the., according to which of the doors Sis open. The corrugated feeding-drums ll, rotating in reverse directions on the opposite sides of the trough-shaped conveyer or belt O, carry the material forward and discharge it thereon in the manner shown in Fig. 5, while the feedregulating drums l2 prevent a too-rapid iow ofthe material,owing to their checking action. As the material is thus fed forward and discharged upon the conveyer or belt O it is carried to the front or delivery end thereof and discharged into the buckets of the elevator O', carried then ce upward, and finally discharged through the hopper E4 upon the pivotally-sustained conveyer or belt O2, whence it is carried upward and deposited on board of the vessel receivingthe coal.

Should the vessel lurch sidewise, both of the conveyer-belts O and O2 will maintain theirrelative positions and carry their loads continuously in the same direction Without shifting or losing any of the material.

It will be understood that the doors 3 may be opened at pleasure and the various portions of the loadv removed, thereby making it possible to always keep on discharging or unloading a vessel upon a substantially even keel.

I do not limit myself to the several details of construction herein shown and described, as it is obvious that many of the features of my improvements may be departed from and still come within the scope of my claims hereinafter made.

Having thus described my improvements, what I claim, and desire to secure by Letters Paten-t of the United States, is-

l. A vessel having a eonveyer located beneath the load to be carried, in combination with means between the load and the conveyer for preventing the former from resting upon the latter, and additional means in the nature of feeding and feed-regulating drums for simultaneousl y checking and feeding the material laterally into or upon the conveyer, substantially as described.

2. A vessel having a conveyer located beneath the load to be carried, means between the load and the conveyer for preventing the former from resting upon the latter, in combination with hoppers adapted to convey the material off the load laterally to the conveyer, together with means located in each hopper beneath the means which supports the load and in the direct path of the inflowing material, said means being adapted to hold the material in check and prevent the too-rapid ad-4 vance thereof to the conveyer, substantially as described.

3. A vessel having a conveyer located beneath the load to be carried, a supporting-roof located beneath the load and over the conveyer; hoppers beneath the lateral edges of said roof and sliding doors on the underside of said roof, in combination with means for causing said doors to close the hoppers, and feeding mechanism adapted to check the flow of the material and to simultaneously feed it forward substantially as described.

4. A vessel having a double-inclined roof located beneath the load to be carried, a conveyer or belt located beneath said double-in-` clined roof, hoppers adapted to convey the material of the load from the carrying-department to the conveyer or belt, in combination terial of the load toward the con Veyer together with feeding and feed-regulatin g drums adapted to simultaneously hold in check and deliver the material directly to the con veyer, substantially as described.

6. A vessel having a conveyer located beneath the load to be carried, in combination with means, as hoppers, for directing the material of the load toward the conveyer and feeding'and feed-regulating drums, one pair for each hopper, said drums being carried by continuously-driven lines of shafting and provided with clutch'mechanism for connecting them to and disconnecting them from said lines of shafting at will, substantially as described.

7. A vessel provided with a compartment undera roof-like structure extending beneath the entire load, in combination with lateral or side openings in said compartment, together with pairs of drums for regulating the flow of the material of the load through the openings and holding it in check, in accordance with the angle at which the material will flow by its own weight, one drum of each pair being provided with means for adjusting it with relation to the other substantially as described.

8. A vessel having a carrying-compartmen t, a double-inclined or roof-like structure located beneath the load to be carried, a conveyer or belt located beneath said roof-like structure, hoppers for delivering the material of the load fromrthe carrying-compartment to the conveyer, means located in said hoppers and beneath the lateral edges of the double or roof-like structure for holding the material in check, in combination with side ledges or pockets adapted to permanently hold a part of the material, in such manner that the upper surface of the material thus held will act as a frictional or sliding surface for the removable part of the load to move or slide thereover, substantially as described.

9. Means for handling coal, iron ore and similar materials, comprising a conveyer located in a compartment beneath the entire load to be carried by a vessel, an elevator ICO IIO

means for moving the free end of said con# veyer laterally, and clutch-controlling mechanism for connecting'both sets of such conveyer-movin g means operatively to a sou roe of power, as a steam-en gine, located also on board of the vessel, substantially as described.

10. A conveyer or elevator pivotally su pported at one end so that its free or delivery end may partake of vertical and lateral movements, in combination With a continuouslydriven shaft carrying three drums adapted to run loosely thereon; a rope running from one of said drums overa sheave supported at the top of a derrck or mast and thence to the free or delivery end of the conveyer; a rope running from each of the remaining drums over sheaves at the opposite ends of a crossbar and thence to points on the opposite side of the delivery end of said conveyer; together with clutch and brake mechanism for connectn g the drums to the shaft and controlling the movements of the conveyer, substantially as described.

In testimony whereof I have hereunto subscribed my name this 24th day of December, 1898.
