I Specification of.Letters Patent.

Patented April 16, 1907.

Application filed October 29, 1906. Serial No. 341,162.

To all whom it may concern:

Be it known that I, WILLIAM E. HUroH- INGs, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Hoists; and I do hereby declare the following to be a full, clear, and exact descri tion of the invention, such as will enable ot ers skillediinfthe art to which it appertains to make and use the same.

My invention relates to mechanism for loadin and unloading ships, andis more particular y directed toward that class of mechanism used in loading and unloading ships containing matter in bulk, such as coal, ore, and similar material.

The object in view is the provision of mechanism that is adjustably positioned upon a ship for loading land unloading the 4 Same.

With these and other objects in view the invention comprises certain novel constructions, combinations, and' arrangements of parts, as will be hereinafter more fully described and claimed.

Fig. 3 is an enlarged detail top plan View of a series of sheaves forming a partof the present invention. Fig. '3a is an enlarged detail plan view of a plurality of cylinders and sheaves positioned adjacent thereto forming a part of 'the present invention. Fig. 4 1s a section taken through the outer end of the boom ssl forming a part of the present invention, together witha movable carriage that is ada ted to move on said boom. Figz is a sectlonal view of part of theboom forming a part of the present invention and showing 1n connection therewith'a plurality of sheaves. Fig. 6 is a sec? tional view of part of the boom and movable sheaves mounted thereon forming. a part of the present invention. Fig. 7 is a sectional view through a pair of 'cylinders'forming aA part of the `present invention-'and-means for hereinafter.

formed of an I-beam and channel-beams positioned on the top and bottom of the'same, as clearly shown in Fig. 4 of the drawings.

Referring more particularly to Fig. 4 of the Y 6 5 I drawings, it Will be seen that the boom A is .of an I-beam, built-up, or channel design. The channel-beams are shown with their anges facing each other, and consequently forming an inclosure; but this is not necessary, as they may be faced outward, if desirable, the channel-beams being used as a lateral stifl'ening means or flange-reinforcement for the I-beam. The trolley-wheels V V are arranged to operate upon the flanges-of the I-beams and preferably astride of the same, as clearly seen in Fig. 4, for supporting a carriage U, which will be described more fully The boom is pivotally secured at C to a turn-table or pivotally-mounted deck-shoe D. Projections C are secured to the boom A vand have mounted therein a shaft C for supporting the boom A in the turn-table D. lhe turn-table D is mounted in ahousing D', as clearly seen in Figs. 2a and as may be desired. The rails E E preferably extend the full length of the ship upon which the resent invention is used, so as to ermit the oom A to be operated from any p ace 'on' the ship. The boom A in operation is raised by a guy-rope G, which is passed through a suitable pul ey upon the mast H for raising and holding the same in an inclined position, as clearly seen in Fig. 1 of the drawings. The mast H 1s lgenerally only supported by thev usual standing rigging or shrouds J but in ease extremely heavy articles are desired to be loaded or unloaded the mast H may be suitably supported by other guy-ropes, as may be desired.

As seen in Fig. 1 of the drawings, the boom A is osltioned at an inclination of approxi- ICO mate y forty-ve degrees; but it will be evi" dent that by operation of the guy-rope G the outer end of the boom A will be raised or low' ered, as may be desired, for accommodating y Salsa top l` various circumstances as the same mayjtro arise. The lower end'of the boom A is mounted in the sliding turn-'table D, so that the lower endmay be reciprocated for positioning the same at any place along the ship, so as to permit the boom A to be positioned at any point for readily and conveniently permitting the operation of the bucketV X, to

be described more, fully hereinafter. Secured tothe lower or pivoted'end of the boom A is a plurality of cylinders, as K and K', which are ada ted to beoperated by any convenient fluid, as steam orcompressed air. The` cylinders K and K are firmly held in position by suitable supports and securing means K K", as clearly seen in Figs. 1, 2, and 7. The operating fluid is adapted to be admitted to either end of the cylinders K and K through the pipes N and the valve-chests O. The operatingfiuid is exhausted from either end of the cylinders through the valvechest O and exhaust-pipe 1a Suitable valves P P are positioned 1n the valve-chests O O and are adapted to be controlled through the connecting-rod Q and the hand-lever R.

As will be clearly seen from Fig. 1 of the drawings, an operator sitting upon the seat S may operate the levers R as may be desired for admitting or exhausting operating fluid into or from either end of the cylinders as occasion may require. Positioned within the cylinders K and K. are a plurality of pistonrods L and L for operating movable sheaves M and M. Secured to the frame that holds the sheaves M and M are bearing wheels or casters m and m', which are adapted to contact with a bearing-plate m, that is rigidly secured to the boom A and extends from the cylinders K and K to any convenient distance toward the outer -end of the boom A, preferably to the fixed sheaves T T. At the outer end of the bearing-plate m is secured a framework T', upon which are mounted a plurality of pulleys or sheaves T T. Positioned on the extreme outer end are a pair of pulleys or sheaves d and d', which are adapted to be postioned in line with the inner pul- M to also pass over the ,pulleys d and d.

leys or sheaves M and M, so as to permit a rope passing over the inner sheaves M arri; will be evident, cables Y and Y are secured to either the framework, upon which the sheaves M and M are mounted, or upon the framework -T and then assed around the pulleys or sheaves T and t e outer sheaves M and M', and finally around the inner sheaves M and M and from thence over the sheaves d and d to the carriage U. Mounted upon the boom A is a carriage U, that is adapted to freely travel back and forth upon the boom. The carriage U is formed with side plates and reinforcing-irons, forming a stiff strong carriage for sustaining the weight of heavy articles without bending or effecting the same as it operates. Mounted within the upper part pairs of ofthe carriage U are a plurality o the channel-irons may be faced the other' way, if desirable. Positioned below the wheels V V is a pair of pulleys or sheaves c and k, over which the cables Y and Y are.

adapted to pass. The cables Y and Y pass over the pulleys or sheaves c and k and thence around suitable sheaves in a bucket X and back to the carriage U and are there secured in place. By this means the bucket X is operated and held in place as may be desired. The line or cable Y, known as the holding-line, is attached to the trolley wagon or carriage U at a, passes thence around a sheave b at the head of the bucket X,

thence upward and over the sheave c in thel carriage U, thence .over the sheave d at the' outer end of the boom A, thence successively a requisite number of times over the sheaves M and T, and be finally fastened to the basefrarne T or the movable frame of the sheave M. The other line or cable Y known as the closing-line, is attached to the carriage U at g, passes from thence over the various sheaves of the closing mechanism hzof the bucket X up over a sheave 7c, through the carriage U, thence over the slieave d at the outer end of the boom A, from thence successivelyl over one of the pairs of sheaves T T and the sheaves M, and finally fastened to the frame T or the frame of the sheaves M.

In operation the carriage U and bucket X being vpositioned at the outer end of the boom A, as shown in full lines in Fig. 1, the bucket isheld closed ybythe closing-line Y and is held in proximity to the carriage U by the holding-line Y. The carriage U is held at the outer end of theboom A against afstop W of any desired construction. This prevents the accidental displacement of the carriage U by pulling the same off at the outer end.

Positioned at any convenient point, prefer-y ably over the center of the vessel, is another stop W', which is adjustable in respect to th boom A and mayfhepqsLiQned at any podin al thelbi Aksusig limit theiwn WatQ/move of themgarrigaqe U. As shown in the drawisjtlie stop VV; is so positioned as to stop the carriage U in such position as to permit the bucket X to be lowered in the center of the vessel; but it will be evident that in case the bucket X is desired to be lowered to one side the stop W may be moved in either direction to stop the movement of the carriage U before it reaches the IOO IIO

-the valves P P for permitting fluid to exhaust from one end of the cylindersK and permit lthe fluid to enter into the other end, thus forcing the sheaves M and M outward; and consequently giving slack to the lines Y Y', which will in turn permit the carriage U to travel downwardly uponmthe boom by gravity. By thus' exhausting pressurefrom one end and permitting pressure to enter the other the speed of the sheaves M and M may be easily regulated and controlled for slowly or rapidly moving thefcarriage U. After the carriage U has descended until it has come in contact with the stop W', as seen at U in dotted lines in Fig. l, the cables Y Y will be permitted to` pay out orbe given slack by the continued outward movement of the sheaves M and M, and consequently the bucket X will descend by gravity to the position shown in dotted line's at X and will be automatically filled by the opening and closing of the bucket in the usual manner of self-loading buckets. As the sheaves M and Ml are moved outward for lowering the carriage U and bucket X they are moved at thesame rate until the bucket X has reached the position shown in dotted lines at X in Fig. 1. As'the sheaves M and M moves outward the carriage U is permitted to descend until it engages the stop W. The carriage will remain in'this position. As the sheaves M and M continue to move outward the bucket X will be lowered, as above described, to the osition shown in dotted lines,'as X. (See 4ig. 1.) After the bucket has been lowered to the position X the closing-line Yl is permitted to pay out slightly by further movement of the sheave M, which will cause the bucket X to open in the usual manner of automatic-acting buckets. After the bucket has been lowered into the hold of the vessel and opened, as just described, it will upon the retraction of the sheave M a short distance close and in closing fill itself with the material in the vessel to be removed. After the bucket has thus been filled and closed both sheaves M and M are moved at the same rate 'toward the` cylinders K and K', respectively, until the bucket has reached its position'at the outer end of the'boom A, as clearly seen in Fig. 1 of the drawings. As the bucket'X is elevated from the hold of the vessel it will iirst engage the carriage U and, impinging against the same, cause the carriage U to travel upward by the continued retraction of the cables Y and Y until the lcarriage U, with the bucket X, is in its outermost position on the boom A. After the carriage-U has been brou ht to its outermost position against the stop Y the bucket X is in position for When it is desired to move the car-- dumping or for being lowered, as may be desirable. The sheaves M may then be forced outwardly a short distance, which will permit the bucket X to open and material contained therein to drop by gravity, or, if desired, a catch may be placed at the stop W and the bucket X lowered to any distance that may be desired and then dumped in the usual manner. 4 y

From the particular arrangement and location of the carriage, bucket, boom, and oi 1er ating means a reasonably compact and readlly-operated mechanism is provided for unloading vessels and the like with as little labor and inconvenience as possible and with the greatest possibles eed obtainable. The arrangement of the trac the full length of the vessel and av sliding turn-table or pivot-plate, in combination with the suporting-boom and mechanism carried therey, discloses a structure that is readily adapted to any-size vessel and for any condition of the same, as the oom and hoisting mechanism may be moved from place to place over the vessel in order to reach all points.
