APPARATUS FOR UNLOADING -BARGES Application .led October 16,1919. Serial No. 331,085.

`To all whom it may cof/wem.'

Be `it known `that I, .LELAND S.V Rosanna, a citizen `of the UnitedStates, .and a resident of the city and county of San Francisco, State of California., `have invented new and useful Improvements in Apparatus for Unloading Barges, of which the following is a specification.

My invention relates-more particularly to the unloading of barges carrying coal, or

. the like; and .its primary object is tofacilitate the transfer yofthe barge load Vto ships, or bunkers, with greater rapidity and more efficiently `than heretofore.

This I accomplish by a combination of handling -and .transferring mechanism. .My invention is kparticularly `adapted, .to the coaling of ships.

By 'referring to 'the accompanying drawings my invention `willbe `made clear.

Fig. 1`is apart side viewof a barge partly in section, equipped with vmy unloading apparatus.

Fig. 2 is a cross .section of Fig. 1 on the section line II-II, with certain .of the parts shown in full for better illustration.

ig. Bis a diagrammatic cross section on the line III--III of Fig. ,1, indicating the relative kposition vof the .bucket and load and barge walls. l

Fig. 4 is a diagrammatic showing of the way my apparatus willfautomatically unload -to correct rany listing .of the barge. 4 Figs. i5 and 6 are details of the discharge hopper to facilitate :distribution of material from the barge to .several points without moving .the barge. 1 l f Fig. 7 is a detail .ofthe skip'and weighing platform. l

Fig. Sisa view of .F ig. 7 andat right angles thereto.

Throughout .the drawings like numerals refer to similar parts. f u

The hull of the barge is indicated by the numeral l, upon-which is erected a gallows frame .2, within which is constructed-the elevator mechanism .adapted to operate and di# rectlthe skip .3. Above rthe barge 1, andsupported by the frame structure 30, and .parallel with the barge length. .is mounted the track .structure 29 .and .trolley 5,0, Aadapted to vsupport the traveling grab bucket 5 from tracks 4; bucket .is fadaptedto pass through .the gallows ,iframe .from .end to end lof the barge 1, as shown in VvF ig. Q and .clears the maximum vvload 6, Iso that @the ,grab bucket may be caused to pick up its unit load from any portion of the barge load 6, and be lifted into a position `clear of the remaining barge load, and caused to travel freely upon thetracks 4 through the gallows frame 2.

Mounted ladjacent to the frame 2,-is the hopper 7 positioned to receive the load released from the grab bucket 5, and convey the load dumped therefrom into the skip 3, when the latter is properly positioned as shown in Fig. 2. The `skip 3 is adapted to travel upward in the gallows frame 2, -and clear the hopper 7 in so doing, and to travel to any required position and dump into the discharge hopper 18, from which the load is distributed as bygravity into the bunkers to an adjacent Aship or wharf. l

The mechanism for .ope-rating the 4grab bucket is controlled from suitable power actuated drums through the 'trolley' line 9, adapted to move the bucket upon the tracks 4, and the bucket operating line 10 is adapted to operate the closing mechanism of the grab bucket. Theseropes pass over suitable sheaves in well known ways.

rihe several `drums for the bucket operation are shown at l1, l2, 13. The skip is intended tobe operated in fa well known way by the wire rope la from the power lactuated drum 15 over suitable sheaves and pulleys, so that its raising and lowering is under accurate control.

To adapt the positionof dumping to any location of bunkerto be.loaded, I arrange `a discharge hopper 8 adapted to travel in ways 1G, supported with rollers 21, and toany suitable vertical position under the control of the wire rope 14 from the power actuated drum 18, so that it may beset at required vertical positionsfat yany time, and the load from the skip dumped therein. lThis dumping is `effected automatically by the skip 3 having located on its side. track-ways as 19, 20, which are adapted t'o slide over the roller or pins 2l of the discharge hopper, so that when thesaid pinzQl is `in engagement between the tracks 19, 2O, of the skip 3, any further vertical .advance of the :said skip will cause the skip to tilt so that'itsiconteuts will be .discharged `into the .hopper 8. This dumping position is indicated in the dotted position 22; discharging the load by gravity into 'the discharge hopper f8.

At 23 I provide a weighing platform suspended from the .scales '24, and on which platform the .skip 3 may normally rest,.be

lll)

ing in such position free from the hoistingv cable and frame, so that the accurate weight of the load placed in the skip 3 may be weighed upon the scales 24.

The means which l prefer to use for freei ing the skip 3 from the hoisting mechanism is best shown in Figures 7, 8, wherein the U frame is provided with long slots 26 on each side, within which slots the supporting andturning axis of the skip 3, as

indicated by pivots as' at 27, may freely 25 at such times resting upon the liooras at 28, free of the scale platform.

In some cases, as in coaling ships, itv is advisable to distribute the coal through several different ports into the different bunkers of the ship, and the placing of the coal in any one of the said bunkers by the trimmer gangs does not proceed with the rapidity with which the barge may be unloaded by my apparatus, and in such cases the discharge hopper 8 may be preferably arranged with a plurality of discharge outlets under the control of a movable gate, or gates, or diaphragm device, which may be actuated as by cable from below, such that any skip load may be distributed through the discharge hopper into any one of a plurality of chutes, so that more than one gang of bunker trimmers may be kept employed by the rate of unloading accomplished with my apparatus. Such a `distributing hopper is `shown liii-Figures 5 and 6, wherein the rolls, or pins 21, engage the uprising skip to tip it into the position 22 so that it dumps upon thebottom'of the hopper 36. From here it will slide by gravity over the movable door `37 and through the outlet spout 38 into a suitable chute, or if the door 37 be raised against the jamb 39 as by the lever 40, the load will fall into the laterally distributing chutes 41, 42. These chutes 41, 42` are under the control of doors, or in the preferred construction shown, a wing gate 43 externally controlled by the lever 44, which in the position shown closes the chute 41l and yrests against stop 47, and in which position it diverts material descending on the bottom 36 through the opening occasioned by raising 37 against the j amb 39, which falling against the door 43,"is diverted into the chute 42. The door 43 is actuated through the external lever 44, by which it may be swung from the position shown into the dotted position 45 against the support 46, at which time descending material will be diverted away from the chute 42` and through the chute 41.

In forming the bunker space in the barge I employ sloping sides as 31, 32, and the flat bottom 33, such that the grab bucket in descending vertically will in its open position fully cover the floor with 33,' as indicated in Fig. 3.l f j f `With my apparatus itwill be seen that in the event of any unequal lateral distribution'of the load 6, causing listingl of the barge, as indicated at 34 (Figs4) the grab bucket will, under the actionof gravity, au tomatically `swing into a position to take the load at the heaviest part, and thus act, at alltimes, to correct any listing; resulting in the maintenance of' perfect trim or equilibrium. of the unloading barge. The operation is as follows: My bargebeing loaded, as for example, with coal is brought alongside a ship thatis tobe coaled, and a suitable chute, or chutes. isplaced-between the discharge hopper 8, as indicated at 48 (Fig. `2), and the ships bunkers, or bunker ports, the elevationl of the discharge hopper 8 is set through the action ofthe drum18-and cable 14, so that the `coal will distribute by gravity from the hopper 8 into theships bunkers through the chute 48; the grab bucket 5 is now caused to descendby the 'cable lineor lines 35, anda `load picked up,the bucket being closed by the action 'of the cable 10. The loaded bucket is now raised and then' transferred alongthe tracks 4I by the trolley line 9. The several cable lines 35, 10 `and 9, being respectively operated by power drums, as required, as 11, 12, 13, until the bucket 5 occupies a position over thehopp'er7, at whichtime, the line 10 is released' by the operator `at the drum 12, and the load dumped, when, under the action ofV gravity a iow will occur into the skip 3, which has been previously set into the"po`sition shown in Fig. 2. The skip and its load are now weighed on the scale platform 23 by the scale beams 24, and the skip 3 is thereafter raised by the cable 14, through ways 17 and'U frame 25 engaging axle pins 27; through the action offthe power drum 15, until the tracks 19, 2 0, `ofthe skip 3, in its upward passage engage between them the pins, or rollers, 21, located on the ydischarge hopper 'mechanismv 8, causing the skip to tilt over, pivoting at such time on the axle pivots'27 within the yframe 25. The skip in tilting to the dotted position as v22 will transfer its load by gravity into the dischargev hopper, and thence into the ship through anyone of the several chutes and to any of the several positions desired, depending upon the position of the vcontrol gates 37 and 43 which determine itspassage through any one ofthe several outletsof thedistributing hopper 8.

a I prefer tomake the-capacity ofthe skip 3 slightly largerlthan `the capacity of :the

i bucket 5, so as toavo'idthe necessity .for any and inconvenience of controlgates andthei operation for the said hopper.

In the longitudinal operation of vthe bucket 5, it is preferable to direct the :successive trips ofthe 'bucket 5so as to .equalize the rate of .longitudinal lunloading. This rate will `be entirely automatic, `the grab bucket at all times will yswing laterally to that portion of the cross section carrying the greatest load and 'thus .at Aafl-l times correcting any list Attention is directed to my Patent #1,370,226, issued March 1, 1.921, wherein is set forth `further disclosure and .claims for improvements in barges. v 1
