and useful Improvements in Loading and Unloading Devices, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to the art of and to appliances for handling and transferring loads. It is thought to be capable of general application. Ho.wever,.it was primarily designed as a coaling device for vessels, and in order to be clear and concise the present statement will be restricted to this single application considering that all its uses can be inferred therefrom and that the character of the load handled or transferred has no bearing either on the construction or on the operation of the device. j

It is of common knowledge that steamships which are bound upon long voyages orare constantly in service must carry a large supply of coal wherewith to generate their steam and that the time and labor spent in putting this ply for want of time.

coal aboard (like the cost of the fuel itself) are wholly chargeable to the expense account. Anything, then, that will operate to reduce the time and labor thus consumed will eHect just so much of a clear saving on the capital invested; but so far as l am aware nothing better for the purpose has hitherto been devised than the sling or rope and bucket and chute contrivance with which some wharves and lighters are equipped. To take in coal with such facilities where the same exist is a slow process under the most favorable conditions and oftentimes masters of vessels prefer or are compelled to resort to the primitive method of coaling with baskets and wheelbarrows in order that their coal may be run in through all available ports at once, a method of coaling :which necessitates the em ploymentof an army ,lof toilers trooping up and down narrow planks land who are not all endowed with a placid dis- Vposition nor all addicted to the use of the most Delays cannot be avoided 'Irefined language.

and .similar methods,

even by following tl and it is no infrequent occurrence for a vessel to quit coaling and leave with a short sup- My invention has for its especial'object' tp supplant basket-coaling and theylike or any known substitute by providing an efficient de- Vice whereby a ship can be coaled quickly, y

quietly, and at comparatively small expense and withal consisting of but few parts whose functions can be comprehended without effort by the dullest intellect and the operation whereof will not be fraught with danger for noi` be impeded by the careless or the idiotic. This device is intended to do away with," every form of irksome manual labor usually i;

connected with the loading of a shipwith coal, except what is strictly necessary to put the coal into carriers and to trim the bunkersinto y 1 which they are emptied. It therefore includes suitable carriers and means for transferring 1 them from the place of supply to the ships hold, means for guiding them on their line of travel, and means for .swaying them off theirv normal course to clear obstacles, and generally it consists of the construction, arrangement, and combinations of parts set forthn the following detailed description and further s pointed out in the subjoined claims.

In the accompanying drawings, Figure 1,;'- shows an elevation of one form of the device that is suitable for Steamers of the middle and;

smaller classes, the view showing also part of y such a steamer in diagrammatic cross-section and a like section of a .wharf from which the supply of coal is supposed to be taken. Fig. 2

-.is a similar view illustratinga modified form of the invention. Figs. 3 and L.tare details of a bail attachment specially desigped to enable the carriers to be hooked and suspended in such a way that they will not turn while in transit. Fig. 5 illustrates the invention applied to a Steamship of the largest class, the latter being shown incross-section diagrammatically and represented as being coaled at once from'both sides. Fig. 6 is a detailed view in perspective of a hinged arm used ln-connectlon with the preferred construction thereof when the same is to be applied as in Figs. l and 5.

Figs. 7 to 10, inclusive, are details pertaining to the most complete form of carrier comthieforme'r transferring it from the loadingpoint to the placepLdeposit in the ship. Confncting lines or tracks, as c d, Figs.' 1 and 2, ,arranged vto traverse the vessel abeam and also to run throughV it lengthwise in the di-s IOO .therewith,,thelatter receiving the coal and the said carriers or any of them and shows J destined to reach orenter.

rection of the keel are added to complete the invention and adapt it to various conditions. The different forms of ships or vessels (shown in Figs. 1, 2, and 5) are respectively lettered e, f, and g, and their several coal-ports are designated by it. By preference one arm ais provided for eachport i and likewise one carrier will be allotted to each arm, usually. The aforesaid arm and carrier can be conveniently operated together in yeither of the two ways illustrated in the drawings-that is, by suspending` thecarrierfrom the arm, as represented in Figs. l and 5, or else having the arm support the carrier from under,as Fig. 2 showsr In either case the arm is preferably made double, as detailed at Fig. 6, that the carrier may have a proper and secure'bearing thereon and may always be correctly positioned with regard to th'eport which it is Fig. 6 accordingly shows the said arm composed of two flat metal bars facing each other and kept parallel at a suitable distance apart,'so that their-upper edges z' j will lconstitute a pair of rails and "afford a track or railway either for an upper truck c 'or `an vvunder truck l of the carrier. Both these trucks are used with the carrier illustrated in -Fig. 2. The two said bars of thearm a, it will-be seen, are united at the` outer end, and at the inner end they are adapted to be hinged to, at, or bythe side of the vessel in various ways, threeof which are examplified in the drawings, and will -now be briefly explained.

First, 'in accordance with the plan disclosed in Fig. l, wherein the ship e appears aslying alongside of Iand coaling from a wharf p, the do'uble farrnfa-is'hinged by its two said bars or members that make' up the track just spoken of'to the outer end of the previously-mentioned inside track c, which is of corresponding` gage and projectsinto the upper part of the port/Lto which the-arm belongs. Thetrackc is-suspended from` a deck-beam m and adjoining timber n by lateral hangers o.

The hinge-jointisI such -that when a is fully raised at its outer end it is-'somewhat inclined inward and downward, as -indicated by the.

dotted lines, and forms with 'e a continuous track vorrailway for the 4upper truck /f of the carrier to ride on. This-arrangement, therefore, allows the carrier to be hung on the arm andl when suiiiciently elevated lto slide by gravity through the port and into the ship e, where it can be emptied anywhere along the line c, its branches, or connections.

Having reference Vnext to the system exposed' in Fig. 2, (in which the ship f is shown as coaling also from the wharf p on one side,) the hinging of the-double arma here is to the outer end 'of a short corresponding. track q, laid across the sill of the port i. A'duplicate arm a' islikewise'hinged to the inner end will form together a continuous railway for the carrier b from the wharf p to a convenient point between decks in the vessel f. The carrier in the present instance is entirely on or above the railway on which its under truck l bears, and upon the arm a being elevated the said carrier will roll ofi it onto the track g, past the port L, and onto the arm a' inside the ship. The coal may then be dropped into the bunker from the arm a or farther in by switching the carrier onto the overhead track d, before mentioned, by using the upper truck c and appliances thereto appertaining.A The track d, it will be observed` is supported from with the carrier thereon-may rest on therwharf whilea charge of coal is being taken, the hinge connection of the arm having su-fiicient.4 play to allow it notwithstanding `the sway of the vessel by the side of the wharf. This construction, (represented in Fig-2,) permits the use of a carrier of greater height and consequent capacity than Where the carrier is hung from the arm-that is to say, with ports of same size. It, therefore, would expedite the coaling through small ports, and. if thel upper deck be low, as shown, the switching to the over head track d can easily be effected after lowering the arm a' and carrier supported thereby, as the dotted lines suggest.

Passing to Fig. 5 where the ship 'g is supposed to be coaling simultaneously 'on both sides from a wharf p and a lighter r, this view shows arms a ahinged each above its respective port L, and having each a suspended carrier discharging into a chute s, located in the port and leading down into a pocket t in the ships hold. It is evident that by providing one arm for every port and working the two sides of the vessel at the same time, as indicated, the largest Steamship afloat can take in her supply of coal quite'speedily land satisfactorily, much more so than cany be accomplished by pursuing the old-fashioned method hereinbefore referred to. Theoperation of arm and carrier in Fig. 5 is likethat in the preceding Figs. l and 2, excepting that IOC IlO

the carrier discharges at the side of instead of within the vessel.

Usually, as in the three exam-ples herein given, the arm a will be hingedl centrally of its port, either above or below or Within or opposite the same, and in each case it will reach down from the ships side to the vdoek or wharf, or sufficiently near thereto to admit of the carrier being readily attached or detached or mounted and dismounted. When the carrier is-suspended from the arm, the downward movement of the latter may, if desired, be limited so as to simply allow the carrier to be conveniently hung or .unhung by providing an adjustable stop, which may ,con-x sist of a ball u, Fig. 1, fastened to the lower end of a rope or chain n that is passed upf wardly through an eye a; on the arm and is secured by its upper end to a boom above. (Not shown.) The stop u is adjustable, in that its suspending rope or chain o can be lengthened or shortened or the boom to which the latter is hitched can be raised or lowered, so that when the carrier touches the wharf or other resting-place the stop will yet be some suitable distance below the eye .fr and permit IO a proportionate downward movement of the arm relatively to the carrier, the connection between which can then be severed or restored easily and 'without impediment. This is not, however, an indispensable feature of the invention, which may be used with or without it. As to the raising of the arm with the filled carrier, that can be effected in various ways by power within or without the system. I have shown only rope-tackles y, which may be hanging from a boom, as .e in Fig. 2, and operated in any suitable manner. The inside arm a' in the said Fig. 2 is lowered and raised with similar tackle secured to the under side of the deck above it.

An upward bend 1 and adjoining downward curve 2 are provided at the outer end of the arm a to properly hold the carrier b and its attachments when the said arm is lowered and again when it is raised previously to the y hinge-joint being closed. Another similar curve 3'may also be formed at the inner end of the arm, as shown in Figs. 1 and 6, if it. be desired to momentarily retain the carrier as it is about to enter the port d, so that its safe passage therethrough can be insured, and,

generally, it may be stated that such curves and bends in the arms a, and a' are contemplated as will respectively adapt them to high and low positions.

40 The aforesaid carrier comprises the following-named parts, to wit: a box-like or bucketlike receptacle or other suitable form of container, the one shown being lettered b, and havinga bail numbered 4, the aforementioned upper and under trucks tand l, a hook 5,

adapted to grasp the said bail of the container, and an intermediate hanger 6 between the said hook and the containers upper truck. A few words only need be said relatively to the construction or function of these respective parts.

As above intimated, this invention is not concerned with any particular form of container. The form shown, however, has been found serviceable and satisfactory. lt is provided with a drop-bottom and'fwill work well whether suspended from the hinged arm or wholly mounted upon it. The trucks k and Z have flange-wheels, (best seen in Figs. 2 and 9,) and thereby are adapted to maintain the container in a straight line as it moves on or along the arm a or a' or the tracks c, d, or q, the connections between the said container and trucks being made properly rigid at all times. Upon the middle portion of the bail 11 is formed or provided a boss 7 having two parallel pendants or drooping cheeks 8 and 9, between which the lower curved'part of the hook 5, flattened at this point, is inserted and snugly fitted. The arrangement is such, as will be seen by referring' particularly to Figs.

1 to 4, that the bail remains fixed relatively to the hook, and consequently the suspended container cannot turn with respect to th 'other parts of the device only in so far as th 75 hook itself is caused to turn. The intermediate hanger 6 is rigidly fastened to the truck it' and extends downward from between the parallel members of the-arm a. lts lower portion is made into a ring 10, in which aseg- 30 mental block 11 is seated. The shank 12 of the hook 5, which shank is made round, passes through a longitudinal slot 13 in the bottom part of the said ring and also througha round hole 14 in the center of the said block in such 85 a way that the hook may turn axially within the said hole and also oscillatc with the segmental block in the direction of the Said slot. (See Figs. 2, 7, 8, 9, and 10.) Now the hook is held to the hanger by a nut 15 and a Sec- 9 ond block 16, placed upon a centrally-raised part of the segmental block 11 and having a square hole 17, in which a correspondinglysquared portion 18 of the hooks shank is fitted. The said block 16 and centrally-raised 95 part of the block 11 have matching radial corrugations 19 2O on their respective faces and are superimposed face upon face. As the hook cannot be turned without the block 16, owing to its being fitted or socketed in the square hole thereof, it will be understood that neither will turn without suflcient force heing applied to cause the corrugations 19 and 20 to rise over one another and admit of the said block 16 being rotated upon its sublying 105 companion block 11. Therefore it is apparent that the hook, whose position determines that of the container, will remain normally as these blocks may be set one upon the other and that if it be swung sidewise either way 11o along the slot 13 the container can be held and steered at any required angle to turn a corner, clear a post, or avoid an obstacle. The hook, it need hardly be remarked, stands with the slot when hooking onto the containerthat is to say, in the position indicated in Fig. 2 or at rigl'it angles to that given it in Figs. 9 and 10. In some cases the hook may be connected directly to the truck and the intermediate hanger left out, as suggested in Figs. 1 and 5; but when both are employed (combined as described) they coact and mutually contribute in making the device more complete and capable of being successfully worked under most unfavorable conditions. Arched braces 21, Fig.6, are used to strengthen the arm a, on which the upper truck/r is made to run. As to the arm that carries the under truck l, its parallel members may be tied directly one to the other for a like purpose.

I have illustrated three Ways of coalinga ship With the aid of my invention, which 'manifestlyY are based on the same fundamental principle, and although the conditions prevailing on different vessels may demand further modifications of the original plan l believe such will ever be found to have the one common foundation. No limitation therefore is intended concerning the number or nature of these modications, which may be of, in, or tothe various structural parts of the dcvice, their location, mode of attachment, direction of motion, &c. No restriction either is made as to the uses to which the invention can be put, .since the carrier in any event can be easily altered to suit the nature of the raw or manufactured product to be handled, and it is really immaterial Whether the hinged arm be employed in connection with a ship or iioating structure or with a building or even amovable object on land. For the sake of clearness and brevity the invention has been described and will be specifically claimed herein as a coal-loader for vessels; but it is no stress of mind to conceive of its adaptation to the storing of goods in a Warehouse or the loading of a certain category of cars or landvehicles such,for instance, as may be used for ltransporting sugar-cane from the field to the mill or for other special or general purposes, and While thus far I have referred to the loading only it is obvious that the invention is just as much applicable to the unloading, which simply involves the reversal of the operations hereinabove set forth.
