A Application filed February 19, 1903. Serial No. 144,071. (No model.)

To @ZZ whom it may concern:

Be it known that I, CHARLES H. ANDERSON, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Cargo-Conveyers; and I hereby declare the following to be a full, clear, and eXact description oi' the same. l Y

My invention relates to an apparatus which is especially designed for conveying cargo or other material from the holds of vessels or like receptacles to places'of deposit more orless distant therefrom.

The object of my invention is to unite in a single apparatus all the means necessary to unload any part of a cargo of most any description from any part of a ship, which apwith means for elevating the cargo either -in the form of packages, bales, sacks, or in bulk in the form of coal, coke, loose grain, or other material of similar description. Lateral and supplementary feeders are disposed fore and aft and in the wings oil the ship, by which the cargo is delivered to the Jfoot of the leg,which is designed to be lowered into the cargo as the latter is removed from the vessel and to raise the cargo and deliver it upon a horizontallytraveling carrier suitably suspended and adjustable with relation to its support, and with relation to` which carrier the leg is-also adjustable up and down and also adapted to swing to such angle as may be necessary in gathering the cargo within the vessels hold.

My invention also comprises details oi' construction which will be more fully explained by reference to the accompanying drawings, in which# Figure 1 is a general elevation oi' my ap- -paratus Fig. 2 is a general plan of same; '.Fi'g. 3 is a side elevation of elevator-leg. Fig.

Fig. 21 illustrates the connection ot' the conveyer-frame B' to the saddle and shows the Fig. 22 is an enlarged planview, broken away, of the lefthand end of Fig. t. Figs. 23, 24, and 25 are details of the cross-head and connections.

The elevator-leg A consists of a verticallydisposed steel lattice-work frame, which is suspended in a saddle 40, (to be described later,) carried at the outer end oi' a horizontal carrier frame or boom B, the inner end ot' which carrier B is in turn supported upon a tower, derrick, mast, or equivalent support, as C, which support is adapted to stand upon a wharf if the vessel is to be discharged upon the same side, or it may be mounted upon a barge, as here shown at I), which is located bythe side of the vessel opposite from the point of cargo delivery. The method of sup- Iporting the'elevator-leg is such that it may be moved up and down with relation to the boom Bto suit varying heights of tide, position of vessel, and depth to which the elevator may have been sunk into the cargo, so that whatfever position it may occupy it -1s adapted, iirst,

'to receive the cargo 'from its laterali'eeders in Y uA is well illustrated in Figs. 3, 4L, 5, 6, 7. It

Fig. 8 is a dia- IOO comprises the endless flight-carrying chains 3, passing over the sprockets 4 at the ends of the frame. Between the planes of said chains is a floor or cargo support of pipes 2 or the 'like adjustable with relation to the flights 3.

The latter extend transversely between the chains and serve as supports upon which boxes or packages of any description may be placed and raised, the boxes or burdens resting against the floor 2 and being supported in front by the adjustable guides 5. The attachment of the flights to the chains is shown in Fig. 19 and is such that they may be readily inserted or removed and the spaces between them changed at will. The floor is adjusted with relation to the ights to suit the size of the packages, so that the latter are supported against the floor in their upward movement. rlhe guides 5 are so located with relation to the flights that they prevent the packages or burdens from falling outwardly and retain them in place until they arrive at the point where they are to be discharged upon the horizontal shore carrier B'. These guides are preferably made in telescoping sections, as in Fig. 3, and may be connected at their upper ends with carrier B', as at 5b, whereby they are regulated relative to the depth of the elevator below said carrier. The means by which the cargo is delivered to the foot of the elevator and the means for operating the elevator, the shore carrier, and the lateral and supplemental feed-carriers within the ship continuously, simultaneously, and from the same source of power will be described hereinafter. The flights may be made in any suitable manner. I have here shown them as made of angle-iron of sufficient strength for any load they are liable to carry and having suitable connections, as at 3b in Fig. 19, with the ropes or chains upon each side. Angle-iron guides 6 also serve to support the ends of the flights and the ropes or chains 3, to which they are attached and by which they are moved. 1n order to adjust the floor with relation to the flights, l have shown longitudinal shafts 7, carrying pinions 8, which are adapted to engage with slidable rack-frames 9, Figs. 6 and 7, said rack-frames being at right angles to the line of flights or transverse to the length of the elevator and supporting the floor 2. These shafts are journaled at their ends in sleeves 23, carried by the shafts of sprockets 4, and are turnable by means of transverse shafts 10, Fig. 4, and worm-gears 11, so that if small packages are to be transferred the floor may be correspondingly brought toward the flights, and if large packages are to be raised then the floor can be correspondingly moved away from the flights, thus producing such a relation between the floor and the flights that the burden lying upon the latter will be supported against the floor and, passing under the guides 5, pivoted to links 5, will be prevented from falling outwardly until it reaches its point of delivery. The operation of shaft lo is eil'eeted by a hand-wheel 10, For the purpose of correspondingly adjusting' the sides of the elevator and conveyer with relation tothe packages or burdens, so that the latter are properly supported from each side, l have shown guide-bars 12 upon each side, and these guidebars are supported at the inner ends of crankarms 13, fixed upon the upper ends of shafts 14, journaled in frame A. Shafts 14 are turnable by means of worm-wheels l5, Figs. 9 and 10, engaging worms '16 upon horizontal shafts 17, having' hand-wheels or equivalent devices 18, by which they may be turned. 19 represents wheels around which pass the ropes 20, which connect the shafts on opposite sides of the carrier, so that they are turnable in pairs or series to adjust the guides l2 in unison. By means of turnlnufkles or equivalent devices, as at 2l, any slack in the ropes may be taken up. lt will be secu by this construction that the guide-bars or sides 12 carried by the crank-arms may be caused to approach or swing in over the carrier-belt to any desired degree to receive and guide small packages and may be correspomlingly separated for larger packages, thus preventing the packages from getting out of place during their transportation over the carriers. These guide-bars are adapted to both the elevator and the horizontal carrier. 'lhe lower ends of the pipes or strips of which the floor 2 is composed are bent around the shaft of the lower sprocket-wheel, as shown at 22, Fig. 7, and the two shafts 7, carrying the pinions which adjust the floor, are connected to the shaft of the sprocket-wheel as follows: These shafts 7 pass through and are slidable in sleeves 23, which in turn have other sleeves 23u transverse to them embracing the shaft 24 of the lower sprocket-wluel. rlhe sprocket-wheel shaft can thus be moved backward and forward by the take-ups without interfering with the arrangement of the pinion-carrying shafts 7. As it is impossible to place any bracing across the frame to support the end of the floor, it can practically only be supported by means of these attachments, which are plainly shown upon the detail view, Fig. 7. A slight bend or ollset is made in the floor, just above the lower end, as shown at 26, which prevents the load froln binding or pinching against the floor when, as in the case of sacks thrown upon the flights, they might otherwise become iannned between the flights and the floor. \\'hen the burden reaches the point where it is to be delivered upon the horizontal shore carrier llf, it contacts with a triangular block, 27, Fig. l2. which is so fixed that itacts to tilt the burden and discharge it from the vertical elevator-leg upon the transverse carrier-belt ol Bf, which belt is adjustable, as shown in Fig. lo and as will be described later, whereby the space be- IOO llO

tween the end of B and the flights may be varied according to the size of the packages being carried by the flights. This belt has adjustable side bars l2', operated in the same manner as those previouslyldescribed in connection with the elevator A, thus maintaining the packages in the proper position while being delivered by this shore conveyer'. The deflecting-'block 27 is moved up and down by a cable, as 28, which is wound upon a drum, as 29, near the top of frame A. This drum is actuated by a friction-clutch, as 30, Fig.V

22, operated by a bell-crank lever 3l and a rod 32, extending down along the frame to within reach of an operator who may be stationed upon a platform located alongside of the horizontal conveyer and adjacent to the vertical elevator. The deiiector 27, Figs. l1 and 12, may be held at any desired point by apin or bolt 33, entering holes in a longitudinal metal strip 33 upon the lloor 2. 1n order to adapt the block relatively to the floor, the flights, and the size of packages conveyed, its deiiectingsurface comprises a series of conjoined sections jointed, as at 34, and supported at their upper ends rigidly by brace-rods 35, which are jointed and foldable in the middle. Thus by folding one or both of these bracerods down upon the main portion the outer portion of the triangular block will be contracted to any desired degree, so as to clear and be out of the way of the flights when small packages are being carried and-the floor correspondingly brought nearer to the flights. The lower side of the block has the concaved grooves 36, made to lit the semicircular floorpipes 2 and to allow the block thus to form projections, which extend between the pipes composing the licor to prevent sacks or soft packages from being caught at thisv point. When the block is to be lowered relative to the movement of the elevator-leg to suit the position lof the cargo, the clutch is released and a brake-shoe 100, operated by a cord or connection 101, Fig. 22, is applied to the drinn until it has been let down to the desired point. Y

ne means for suspending the elevator-leg and adjusting it vertically in relation to the cargo-level is as follows: A-saddle 40 is secured to the outer end of boom B, and the saddle and boom are suitably supported, as by the whip 4l, from the top of the tower, derrick, or mast C, on which the boom is swiveled and slidable. The elevator-frame passes mast C. Chains or cables 44, attached to the saddle, pass down on each side of the elevatorleg and attach to drums or chain-wheels 45, located near the lower end of the leg. By revolving the drums in one direction or the other' the chains are wound or unwound to raise or lower the leg. Any suitable means may be employed to operate chain-wheel 45 either by hand or by the same power used to drive the burden-carrier on the elevator. I have shown for the latter purpose a rod 39, running nearly the length of the leg, slidable in suitable guides and adapted to be grasped by the operator at any level of the ship. This rod 39 extends nearly the length of the leg, and it connects with the lever shown by dotted lines in Fig. 3, said lever connecting with a friction-gear 38 on the shaft of the lower sheave 51, as shown in Fig. 4, said gear 33l meshing with a friction-pulley on the shaft of thehand-wheel 46, which shaft has the gears 45, which by al chain of gears of any well-known and appropriate character (not shown) drives the chain-wheels 45. In case it is not desired to use the main driving power of the machine the drum may be actuated through suitable hand operating mechanism, as at 46.

The burden-carrying chains 3 and the shore conveyers are operated from a source of power located exterior Ato the ship. Where flights areused---as shown, for instance, in Figs. 1, 3, 4, 5-the driving connections for the elevator and shore carriers are represented in diagrammatic View in Fig. 8, in which the endless driving-belt passes around the sheaves 5l at top and bottom of the elevator-frame. Thence the two parts of the belt approach each other andV pass around idler-sheaves 52 52', thence around the respective inner sheaves 53 53, which direct the two parts one up to and over a counterweighted tension-pulley 54 and the other downward around sh cave 55, uniting with the other part and receiving motion through belt 56, which passes over a pulley on the shaft of sheave 55 and is driven from any suitable source of power. Motion may be transmitted from belt 50 to drive both the shore and elevator conveyers in unison, the` former through connections 50 with sheave 52, the latter through suitable connections interposed between the shaft of the upper sheave 5l and the shaft of the adjacent sprocket-shaft 4. The belt or connection 50"L connects with a pulley on the shaft of pulley 50b on the shore conveyer B, as in Figs. 16 and 2l. The starting and stopping of the burden-carrier on the elevator may be controlled by a rod 37 and suitable clutch mechanism, as at 35lin Fig. 22, and which may represent any well-known and appropriate form of clutch mechanism. By these connections it allows the elevator-leg to be raised or lowered and thrown into any position without interfering with the operation of the driving mechanism or the arrangements IOO ITO

by which it is connected with the shore end of the apparatus. 1n order to allow for movements of the vessel and barge forward or back with relation to each other, the sheaves 52 52' and 53 53 are journaled in swiveled carriers 57, Fig.' 8, which are turnable from one side to the other, so that whatever change of position may take place in the elevator and parts connected therewith this construction will allow the pulleys and their shafts to turn, so that they are always truly in plane with each other, while boom B has universal joints at both ends to allow for independentmovements of the vessel and barge.

1n order to compensate or adjust the length olf the horizontal belt of carrier B in relation to the flights, so that it may be brought near to the elevator when the packages are small and prevent their falling between the two or moved farther away to clear the elevator when the packages are larger, in Fig. 16 I have shown a carriage 76, movable in suitable and well-known guides on the frame of B and having pulleys 58, around which passes the carrier-belt 59. The carriage is adjustable by means of a rack-and-pinion mechanism 77, as shown, to compensate for the lengthening and shortening of the belt, according as the carriage is projected more or less beyond the elevator end of B.

The inner end of the boom rests upon a cross-head upon the support C, and this is suspended by a suitable hoisting-tackle, so that it may be raised or lowered. 1n Figs. 23 and 24 I show the swivel connection of boom and cross-head 102, whereby the boom has a universal movement and the cross-head may be raised and lowered. The cross-head is connected by ropes 823/, attached to eyes 83 on the cross-head and leading over pulleys on the mast C to one of the drums 43. The elevator-leg is also steadied by stays extending .from the top, as shown at 66, to an appropriate cleat or eyebolt or other well-known fastening at 66 to maintain its proper position when being adjusted with relation tothe cargo during the operation of transferring it.

l now come to the means by which material is delivered to the foot of the leg A. Endless conveyers extend laterally fore and aft from the hatchway in which the legis suspended, and each of these lateral conveyors may have one or more supplemental conveyers, as 61, extending into the wings of the ship. These conveyers, of which there may be as many as required, are driven in unison from and with the elevator, which latter, we have previously seen, operates in unison with the shore conveyer. The drivinggear of these conveyors 60 61 and their connections with chain conveyer 3 are as followszThe lower sprockets 4 are connected, through suitable gearing 62, as indicated in Fig. 15, with the drums on the adjacent ends of carriers GO. A line-shaft 60 extends parallel with each carrier 60 and is journaled on the frame thereof and is operated, through suitableconnections, with the drum at the elevator end of said carrier. At suitable intervals these shafts carry gears G01. The discharge ends of carriers (Sl each have a carriage 61, Fig. 111-, provided with rollers G1, which are movable on a track 61, of channel-iron, disposed parallel with shaft GO". The roller end of the lateral carrier 61 runs on the track, and the shaft (10 has the gears 60" at intervals, which protrude through slots in the side ol the channel-iron GO, whereby the belts of the carrier (il are driven. A chain of intermeshing gears are journaled in carriage 61, and by moving a carrier 61 to a point to engage these gears with a gear GO" on shaft 6(7) motion is transmitted to the carrier. '.lhus a package put upon a carrier (51 in a remote part ofthe vessels hold will be taken and delivered upon carrier 60, thence to the foot ol elevator, thence lifted by an attendant, il necessary, and discharged upon shore carrier B, and linally deposited upon the wharf or in the warehouse without further handling than the lirst deposition of it upon carrier (ll.

lu order to lift coal, wheat, or other loose material, it is necessary to employ buckets, as at 3", which are secured to the endless chains 3, so as to be carried upward in the same manner as the flights 3", previously de.- scribed. lheu the buckets reach the level ol the shore carrier, they are discharged thereon as follows: 'lhe chains 3 are caused to change from a vertical to an essentially horizontal travel by direction drums or pulleys (32, journaled in saddle 40, Fig. 13. 'lhe buckets are thereupon tilted to discharge into a chute 133, which delivers the material upon theI shore conveyer, as shown. 'lhe chain ol empty buckets then passes around the direction pulleys or drums Gel and 65, journaled in the saddle, whence they are brought again into a vertical line above the horizontal conveyor, and the empty buckets are tlms carried over the top and returned down to be again loaded. As pulleys 62, G4, and (i5 arejournalml in the saddle, they in nowise interfere with the vertical adjustment of the leg. By suitably-disposed gearing power may be transmitted to revolve the direction drum or pulleys at (Sel to provide a direct pull upon the chains at this point and insure an easy moveanent around thedirection-pulleys. ln the presentinstance power is transmitted to drivel the buclmt-carrying chains through belt 5l), which passes from the pulleys as 53 ol Fig. 1 around the direction-pulleys 7S 79 Si), Fig. 13. Pulley 79 through suitable gearing (indicated at 81) transmits motion to a master-gear S2 on sprocket G4. Thus the leg may be raised and lowered here, as be fore, withoutdisturbing they drivingmechanism. lhere the distance l'rom the elevator-leg to the point ol deposit is very great, the land or shore conveyer B may be.

lOO

made in sections and jointed., as shown in Figs. 17 and 18. In order that the sections may be connected as closely together as possible and to provide at the same time means for tightening the conveyer-belt of B', Iemploy plates* 67 and 68, the former fastened to the end of one carrier-section and the latter slidable on the adjacent end or' the other section and controlled by a screw 69 or equivalent device. Each plate is provided with a half-box 7 O 71 to embrace the'carrier-roller shaft and embraced and held together by a ring 7 2.

Under some circumstances should it be found impracticable to operate the shore conveyers from thebarge, as where the haul is a very long one and the load unusually heavy, the shore conveyers may be run by an independent motor 7 3, Fig. 18, connecting, through belts 74 and gears 75, with the carrier of B'. Having thus described my invention, what I claim, and desire to secure by Letters vPatent, is-
