SPECIFICATION forming part of Letters Patent No. 7 '79,7 58, dated January 10, 190.5.

Application filed July 6, 1903. Serial No. 164,434.

To @ZZ who/n t may concern,.-

Be it known that I, ANGELO Bucci-II, a subject of the King of Italy, residing at Genoa, Italy, have invented certain new and useful Improvements in Oonveyers; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to unloading apparatus,A and particularly to means adapted for the extraction from ships and the like of cargoes in bulk, such as wheat, corn, coal, &c.

The object of the invention is, moreover. to provide unloading mechanism which shall be adapted to receive the cargo from the holds of vessels lying at a greater or less depth below or distance from the wharf and to deliver the same at the option of the operator in a vertical or a horizontal direction or to other vessels, lighters, or cars.

In order that my invention may be clearly understood, I have in the accompanying drawings illustrated a preferred embodiment of thel same.

In the drawings, Figures 1 and ln constitute together a vertical section of the apparatus on the line A B of Figs. 2 and 2a. Figs. 2and 2-a together constitute a plan view of Figs. l and la. Fig. 3 is a transverse section on the line O D of Figs. 1 and la. Fig. 4 is a partial view of the interior of the vertical casing. Fig. 5 is a side elevation of the operators cabin, shox ing a portion of the driving mechanism. Fig. 6 is a partial transverse section on the line E F of Fig. l, and Figs. 7 and 8 are details of the carriers.

Referring to the drawings more in detail. upon the wharf or embankment 1 a supporting bridge or scaolding 2 is constructed', having supports 3, provided at their lower ends with wheels t, so arranged that the bridge may be moved longitudinally of the wharf upon rails suitably placed for the purpose of bringing the same into operative position with regard to a vessel lying at the wharf. Beneath the bridge cars 5, likewise running upon rails, may be placed to receive the cargo unloaded from the vessel. Upon the upper side of the bridge a tubular casing 6 is movably arranged by means of rolling supports,7. rI`he end of this casing extends beyond the bridge, so that it may be brought over the vessel to be unloaded. rIhe outer end of the casing is not integral with nor fixed rigidly to the casing proper, but is formed in the shape of a hood and is connected therewith by means of two Vertical plates 9 and l0, secured to the casing and the hood, respectively, in parallel planes and connected with each other pivotally by means of a strong horizontal bolt or key ll.. These plates 9 and 10 are provided with openings 12, Fig. 6, through which the carriers may pass, as is more fully explained hereinafter. Against the side walls 13 of the hood and externally thereto are arranged side plates 14, connected by a bolt or key 15. A vertical casing 16 depends from the hood and is provided at the lower extremity with a collector end 17, at which point the cargo is received by the carriers. This casing is arranged to be raised and lowered relative to the hood and horizontal casing by the provision of grooves or channels 18, in engagement with corresponding ribs on the side plates 14. By the construction just described it will be understood that the apparatus can be moved longitudinally of the wharf to reach the position opposite a vessel lying thereat, and the vertical casing 16 can be raised and lowered vertically and also adjusted horizontally to accommodate itself to the exact position of a vessel, and that, moreover, the slight movements of a vessel lying at the wharf, due to differences in load and also to the waves and tide, are readily accommodated by the pivotal connection of the vertical and horizontal casing. Above the inner end of the horizontal casing 6 is arranged the cabin 20, which contains an electric motor, steam-engine, or other suitable source of power. The sides 2l of the cabin extend downward below the main body thereof and serve as bearings for a horizontal axle 22, upon which are keyed two toothed wheels 23. The horizontal casing 6 is provided with longitudinal openings or slots 24C, whichV receive the ends of the axle 22 and permit of the displacement of the cabin and the axle 22 longitudinally of the casing in the operation of raising and lowering the vertical casing 16. Around each toothed wheel 23 a lchain 25 passes and also around four bearing- IOO pulleys 26, arranged in the hood. At the bottom of the vertical casing a drum 27 is arranged, which forms the lower turning-point of the chain 25. Guide-plates 28 are arranged on the inside walls of the horizontal casing 6 and serve to support the chain 25` said guides being' connected at the point 29 with the axle 22. At the point 30 on the sides of the cabinwalls are connected two metallic cables 31, eX- tending lengthwise within the horizontal casing 6, passing around the pulleys 32, arranged in the hood 8, the bolt 15 serving as an axle, and thence to the bottom of the vertical casing 16, where they are lixed at the point 33 to the lower end 17 of the easing. It will thus be seen that as the cabin 2O advances along' the horizontal casing 6 toward the vessel the cables 31 permit the casing 16 to be lowered by means of the channels 18 engaging the ribs on the plates 14, and the reverse movement of the cabin serves by the same means to elevate the vertical casing 16.

The chains 25 are connected at intervals by tie-rods 34, which serve as axles, upon which are pivotally mounted iron buckets or carriers 35. Other tie-rods, 36, are located adjacent to the rods 34 and serve not only to hold the chains in the same relative position, but also have an important function in the operation of the carriers, which will be more fully dcscribed. These carriers are provided with a reinforced edg'e or lip 37, which serves asa scoop for collecting' a load. The opposite side of the carrier is extended and provided with wings 38, provided with a slot39, which serves as a bearing' for the axle 34, by which the carriers are suspended. The wings 38 are reduced at 4() to provide a nose 41, with which the tie-rods 36 engage during` the descent of the carriers and serve to hold them in an inverted position, this being rendered possible by the sliding of each carrier upon its axle to the extent of the slot. This feature will be readily understood from an examination of Figs. 1, 7, and 8.

As stated, the cabin 20 is equipped with suitable power, such as an electric motor. The motor is connected in the usual manner with a pulley 42, mounted on the shaft 22, to which are keyed the gear-wheels 23 for driving the chain, as heretofore described. The motor is also connected by a drive-chain 43 with a gear 44, which drives a pinion along' a rack 45, secured to the bridge 2, by which means the cabin is n'ioved back and forth longitudinally of the horizontal casing 6, and thus is enabled to raise and lower the carrier mechanism by means of the cable 31, as previously described. In order to adjust the horizontal casing itself longitudinally with reference to the bridge, the cabin is anchored to the bridge in any suitable manner. (Not shown.) The shaft 46 is A then driven by the motor and by means of the pinion 47 engages with the rack 48, which is fixed to the sides of the casing 6, and, the cabin being fixed, the casing 6 is moved thereby longitudinally upon the rolls 7.

The upper portion of the horizontal case is provided with a cover 48, having hinged doors 50, by which access may be had to the interior mechanism.

From the foregoing description the manner of operation will be readily understood. Then it is desired to unload or transfer the cargo of a vessel at the wharf 1, the bridge 2 is moved upon the rails until it reaches a point opposite the vessel. This movement occurs comparatively seldom, as ordinarily a vessel will be brought to a point opposite the bridge. The unloading mechanism and the vessel having been brought to a position opposite to each other, the horizontal casing 6 is advanced longitudinally toward the water until the hood 8 lies over the entrance to the hold. The cabin 2() is then advanced toward the water, by which means the cable 31 permits the descent of the vertical casing 16 until the lower mouth 17 thereof occupies a position within the hold of the vessel in contact with the goods to be removed therefrom. The apparatus having thus been placed in operative position, the chainwheels 23 are rotated by means of the pulleys 42, and the chains 25, with their carriers 35, are caused to travel in cycle in the direction of the arrows 51. Starting at a position in the upper portion of the casing 6 it will be observed that the carriers hang loosely upon their axles 34, as shown in Figs. l and 7. As they pass around the pulleys 26 in the'upper and outer extremity of the hood 8 the carriers are inverted and by their own Weight slide along their slotted bearings until the nose 41 abuts against the tie-rods 36, by which the carriers are held in the inverted position. After passing' around the pulleys 26 the chains run upon curved guides 52, which may be )rovided with antifriction-rolls and which serve to hold the carriers in an inverted position, having a channel 53, the object of which will be more fully described. As the carriers arrive in their inverted position at the mouth 17 of the vertical casing the chains pass around the drum 27 and cause' the carriers to scoop up the cargo until they are full. In this operation each carrier slides in the opposite directionupon its bearing and takes an upward direction, swinging' freely upon its axle 34. Reaching' the hood the chains pass around the pulleys 26, the carriers swinging loosely, and take a horizontal direction away from the water with their load. Curved arms 54, arranged adjacent to the edge of a hopper 55, engage the lip of the carrier and cause it to discharge its contents into the hopper, from whence they fall into the chute 56. This chute may be provided with a removable bottom and the cargo weig'hed therein by any suitable well-known means. (Not shown.) Thence the cargo is discharged into the car 5 and is transported to any desired position. [n order that the process IOO IIO

of weighing may not interfere with the continuous unloading of the cargo and in order that the same may be transferred to cars upon different tracks, other tripping-arms 57 are arranged adjacent to hoppers 58 and chutes 59, the different sets of discharging mechanism operating alternately, for which purpose the tripping-arms 54 and 57 are mounted upon shafts 60, provided with arms 61, which are adjustable by means of set-screws 62 upon the standards 63. By loosening and tightening the screws 62 the arms 54 may be raised and lowered into and out of an operative position. If instead of unloading the cargo into cars it is desired to transfer the same from one vessel to another, the tripping-arms 54 and 57 are both made inoperative and the carriers, with their load, pass from the hold of the vessel upward, then horizontallyT around the wheels 23 and outward toward the water along the upper portion of the casing until the carriers reach the pulleys 26, by which they are inverted and their load discharged .into the channel 53, whence it is conducted by any desired means, such as a chute, into the hold of the other vessel,

`IVhile the operation of the apparatus has been described with particular reference to the unloading of ships, it will be obvious that the same. is also adapted to the loading and unloading of bins or cars and other vehicles. Moreover, with slight modiiications which would suggest themselves to one skilled in the art the apparatus could be used as a dredge.

or for excavating purposes.

The casings 6 and 16 are preferably tubular, but may be of any other convenient shape and need not necessarily be inclosed, but merely a skeleton framework, serving as ways for the transportation of the chain and carriers. The hood may also be of skeleton construction, having for its essential function the formation of a universal joint between the horizontal and longitudinal casings or ways by means of the pivots 11 and 15, arranged at right angles to each other.
