LIGHTER 0R BARGE FOR HANDLING COAL OR OTHER MATERIAL.

SPECIFICATION forming part 0`l Letters Patent No. 683,246, dated September 24, 1902i.. Application i'lled November 16, 1900. Serial No. 36,692. (No model.)

useful Improvement in Lighters or Barges for Handling Coal or other Material, of which the following is a full, clear, and exact description, reference being had to the accompanyingdrawings,forrninga part of this speciiication, in explaining its nature.

The invention relates to a lighter, barge, or similar vessel for transporting material, pro- 'vided with means Jfor accomplishing its own loading from a stationary pile of material, whether located on a stationary support, like a wharf or land, or upon a movable support, like a barge or lighter, and whether said pile of material is upon one side or the other of said lighter or barge-such, for instance, as would be the condition it' another lighter or barge were interposed between it and the pile of material from which the lighter or barge was being loaded.

The invention is adapted also to be used in delivering the load of the lighter or barge in a similar way-that is, to deliver it to other lighters, barges, or any type of vessel and at either side ofthe barge desired, or altern ately to vessels on both sides of the barge, or to vessels separated from the barge by other vessels, or to stations on land or wharf at either side of the barge.

The invention is further adapted to transfer material from one point more or less removed from one side ot' the barge or lighter to a point more or less removed on the other side and without handling or unloading on the lighter or barge.

The invention further relates to means for weighing the material while it is beingloaded or unloaded and while in the transferring grab, shovel, or bucket.

I will now describe the invention in connection with the drawings, wherein- Figure l is a view in vertical cross-section of a barge or lighter and in elevation of the material-handlingapparatus mounted thereon. Fig. 2 is a view in sido elevation of a portion of the barge or lighter and of the apparatus. Fig. 3 is a view in plan of a portion of the barge or lighter and of the apparatus. Figs. 4c and 5 are views in detail,

enlarged, representing devices for weighing `it and of means for adjusting the trolley-ac# tuating rope and rope-blocks, to which referf ence will be hereinafter made. Fig. 9 is a View -in elevation of the complete barge and handling apparatus. Fig. l0 is a View in plan of the parts represented in Fig. 9.

The invention comprises a vessel for transporting material, such as a lighter o1` barge, having a hatch of very nearly the length of the vessel or ot' that portion which carries the cargo and having mounted upon its deck or other support, upon each side of the hatch, tracks or rails upon which the material-handling devices may be moved lengthwise the vessel.

The invention further comprises a peculiar material-handling apparatus mounted upon the rails or tracks of the vessel, to be movable lengthwise the hatch and which comprises a tower or support so constructed as to carry upon each of its sides a trolley-supporting boom and also so constructed as to permit the inaterial-handling grab, shovel, or bucket (which for brevity hereinafter will be referred to as the grab) to be lowered to the hold of the vessel and raised from it through or in line with the vertical center of the tower and to be moved in either direction from said center outwardly as soon as said grab has cleared the deck of the vessel and also to be moved through it from one boom to the other. The apparatus thus contains what I have termed a we1l-that is to say, an unobstructed passage from the boom-section down through the base of the tower, so that the grab may be lowered vertically through the center s of the apparatus into the hold of the lighter for the purpose of loading or unloading. It has wheels or rolls, which are mounted upon said rails or tracks, and it is adapted to be locked in any desired position lengthwise the vessel, and it carries the means for moving the trolley, for operating the grab, for weighing the material, and for adjusting the booms, as will behereinafterdescribed. Ihaverepresented it as used in conjunction with a stationary engine carried by the vessel, preferably at the IOO stern; but I do not wish to be understood that this limits the invention in any way, as the engine may be mounted on the rails or tracks with the tower or support to be movable with it.

Referring to the drawings, A represents the vessel; B, the hatch; C, the engine; D, the movable tower or support; a ct, the rails or tracks upon the vessel, one upon each side of the hatch.

d represents the base of the tower or support; d, its wheels or rolls, which bear on the rails or tracks d2, the locking device for locking the tower or support in a stationary position to the vessel.

From the base d rise the two sides of the tower or support d3 d4. These sides are strongly braced and are connected with each other at the base d and at the top d5. They support midway their height a stationary intermediate or central section E of a trolleyboom, the said section consisting of the parts e e', which are separated from each other throughout their length and form rails or tracks upon which the trolley F is movable. Below the section E of the boom, between the sides d3 d4 of the tower or support, is the high wide opening F', extending from one side of the tower to the other, and in which the grab is vertically movable and from which it is horizontally movable at any point between the base d and the intermediate boom E. The base d has an opening of substantially its full width,through which the grab is moved vertically to and from the hold of the vessel. This opening forms an essential part of the well, through which the grab may be moved vertically from a position near the boom to a position under its central portion and belowT the base of the apparatus. The parts e e of the boom-section E cannot be connected with each other, as the grab ropes must play through the space e2, which separates them. Consequently there can be no tie uniting the two sides d3 d4 between the top of the tower or support, where they are joined together,and the base.

To each end of the central boom-section E there is attached a boom extension, and these boom extensions are lettered E E2, respectively. I prefer that one of them be considerablylonger than the other, although this is not necessary, and in the drawings it will be seen that the boom extension E2 is considerably longer than the boom extension E. This is for the purpose of providing a sufficient length and arrangement of boom to permit the grab to take material from or deliver material to a point or position considerably removed from the side of the lighter or vessel and beyond an intermediate vessel or other object, if desired. In other words, it extends the range of usefulness of the device. Each of these boom extensions is attached to the central boom-section E to be movable out of operative position and preferably to such a position as willrprevent it from interfering with rigging or any obstruction at the side of the vessel, and I have represented them as hinged to the ends of the central section in a manner to permit their being turned upward to a vertical position. I do not intend, however, to coniine myself to this disposition of the boom extensions when not in use, as they may be swung downward to a vertical position or horizontally backward or forward to a horizontal position lengthwise the vessel, if desired. Each of the boom extensions has trolley-tracks in continuation of the trolleytracks of the central section, which are separated by a longitudinal opening in which the trolley and grab ropes move. The boom extension E is connected by the hinge e3 with the central section E, and it is supported in horizontal operative position by a stay e4, extending from the top of the tower orsupport D to the outer end of the boom extension. It is also supported when in a horizontal position by the topping-lift e5, by means of which it is also turned upward by a person on the deck to an inoperative position and held by itV in a vertical position against the bar e", which prevents the boom from being swung inward past its center of gravity. In other words, it so holds the boom that upon release of the topping-lift the boom will swing outward and may be lowered by the topping-lift to its horizontal position without requiring that it be first moved away from its rest or bar e6 by hand. The boom extension E2 is connected with the central section E by the hinge e7. It is supported in a horizontal position by thestay e8 and topping-lift e9, which also serve to lift and hold it against its rest or stop ew. Vhen both booms are in a horizontal position, the trolley F may be moved fromv the outer end of the extension E2 across the central section E to the outer end of the section Ethat is, the length of these three sections determines the extent of movement of the trolley. The three sections will be used at the same time for the purpose of transporting material from a positionv below the boom E2 to a position below the boom E', or vice versa, or for the purpose of transferring material to the lighter or barge irst over one of the boom extensions and then over the other boom extension, transferring the material from the lighter in alternate directions and to two piles, positions, or vessels. l/Vhen both boom extensions are in use, the trolleydrawing ropef will run over a sheave at the outer end of each boom. (See Fig. 3, wheref represents the sheave at the outer end of the extension E, and f2 the sheave at the outer end of the extension The trolley-drawing rope passes from sheave to sheave on the upper side of the boom, the trolley itself forming a connection between the ends of the rope and upon the under side of. the boom from the sheaves f f2 to the two sheaves f3 f3 at the center of thecentral boom-section, from whence they pass to the two sheaves f4 f4, thence to the sheaves f5 f6 on the base d, and

ICO

IIO

from thence over the deck of the lighter to the rope-winding devices of the engine. When either of the boom extensions E F.2 or both of them is or are not used, it or they will be turned upward, and, if preferred, the sheaves ff2 will then be moved inward to the outer end or ends of the central extension and the trolley-rope` be correspondingly taken up or shortened at the engine in any desirable way. I would here remark that not only may either extension be used at will, but also that the central section may be used alone.

In order that the trolley-sheaves f" f2 may be moved from their outboard to their inboard position and may be looked in such pov sitions, each one is mounted in a sheave block or holder, and a description of one and manner of using it and of locking it in its two positions will suflice for both. f7 (see Figs. 6, 7, and 8) represents one of these sheaveholding blocks. It has side guiding and holding extensions f8 fg, which enter longitudinal guiding-recesses flof11 on the inner faces of the two sides of the boom, the block f7 being,

in effect, a carriage movable lengthwise the boom extension from the outer end of the extension to the outer end of the central section. Ihe block is locked in either position to which it may be moved by a long locking pin or bolt fu, which passes through holes in the boom sides and through a hole in the block and is locked to the boom by a nut. (See Figs. 6, 7, and 8.) The sheave-block f7 upon the removal of the bolt and the lifting of the extension will slide by gravity from the outer end of the boom to the outer end of the central section, where it is looked to the central section by the locking-bolt in the same manner in which it was locked to the boom end. (See Fig. 6, where the sheave is shown in dotted outline at the end of the centrai section and as locked in place.) To move it outward from the end of the central section to the outer end of the boom extension, there is used a draw-line f13, which is fastened to the outer end of the block and'passes over a sheave]C14 at the end of the extension and thence back to the support. Said .line flis shown in Figs. l and 6. It is evident that when either boom is upturned its sheaveblock may be kept at its outer end, the rope running therefrom being guided to the trolley by pulleys suitably placed, or instead of moving in the sheave-block in the manner described a temporary sheave-block lnay be placed at the end of the central section next the upturned boom around the sheaves, in which temporary trolley the necessary ropes may be run.

In order that the lower horizontal portion of the trolley-drawing rope f which passes under the trolley may not interfere with the grab-ropes, each trolley-rope boom-sheave f f2 is set obliquely in its block, so that the trolley-rope passing around it will be offset in position on its under side from a central position lengthwise the boom, and thus be at one side of the longitudinal opening of the boom. (See Fig. 8.) G represents the grab, shovel, bucket, or other material-transporting device. A grab is represented, and it has a lowering and hoisting rope Q and a closing and opening rope Q. Both of these ropes pass between the rolls of the trolley F in the usual way. The ropes lead past the guidingpulleys g2, Q3, and Q4 at the top of the tower or support to the pulleys Q5 Q6 above them and over which they run to the pulleys Q7 QS at the base of the support, from which they run over the deck of the lighter or vessel to the engine. is guided by the pulleys Q2 Q3 'and the other by the pulleys Q3 Q4. It will be understood that in operation the grab-ropes may be either operated when inclined from the pulleys in the direction shown by full lines in Fig. l.tor when in the position shown in dotted lines in said ligure or when they may be substantially vertical. In the first event` the pulleys Q2 Q3 are principally operative with the ropes, while the pulley Q4 is substantially at rest. In the second case the pulleys Q3 Q4 become operative with the ropes, while the pulley Q2 is substantially at rest, while in the third case all pulleys assist in guiding the ropes. It will further be noticed that the pulleys Q2 Q4 are in horizontal line with each other and the pulley Q3 is below said line, but in the saine vertical plane, and that their peripheries are deeply grooved and that the pulleys are so placed that their edges are very nearly in contact and arc not separated from each other by a space suliicient to permit the escape of the ropes from the grooves. It will also be seen that the grooves of the wheels are deep and the ropes are always contained in them and that the rope Q will automatically pass upon the transfer of the trolley from one side of a vertical central line to the other side on its support from the pulley Q2 to the pulley Q3 and that the rope Q will pass upon said transfer from the pulley g3 to the pulley Q4. The pulleys Q5 Q6 are represented as mounted upon a shaft or pin Q9, supported at its ends in the arms Q10 of a yoke Q11, and this yoke is hung or snspended by means of the links Q12 upon the scale-beam Q13, which is itself hung by the links Q14 from the cross-beam Q15 of the tower or support. The links Q12 Q14 have knife-edge connections with thebeam,andthelinksg14are the trunnions or centers upon which the scale beam or lever moves. The outer end Q16 of Athis beam or lever Q13 is connected by the jointed rod Q1'T with the scale-lever Q1S of the weighing scales G', which are preferably, though not necessarily, mounted upon a platform carried by the support or tower at the level of the booms or other lever. This sealebearn Q18 is pivoted at Q19 and connected by rod Q20 with the Weighing-beam Q21, which is of the common type of weighing-beams and need not further be described. It Will be seen that by this construction the entire One of the two grab-operating ropes IOO IIO

weight of the grab, its ropes, and its contents, when it has any, are supported or are supportable by the scale, and this provides means whereby the weight of the contents of the grab may be correctly ascertained at any time during the transfer of the loaded grab from a receiving to a delivery position whether the grab is in motion or not.

The supporter tower may be moved upon the lighter or vessel from one position to another by hand or by power, and in the drawings I have represented it as moved by the engine by means of a draw-rope H, which extends from a fixed post h about a sheave h on the base of the tower or support, thence about a block h2, fast to the deck, and thence to a winding-drum on the engine, and a drawrope I-I, the end of which is fastened to a stationarypost h3 and from thence extends about a sheave h4 on the base of the support or tower and to a winding-drum on the engine. It is desirable that the booms be supported at such an elevation as will permit them to overhang the decks of the highest vessels when in their highest positions sufficiently to allow the unimpeded horizontal movement of the trolley and grab. It will be noticed that the tower has a wide base of very nearly the width of the lighter or vessel and that one of the boom extensions assists when both are horizontal in counterbalancing the other and adds to maintaining the equilibrium of the tower and of the structure, the structure having what might be termed with some degree of exactness a cantaliver organization. It will be seen that the apparatus provides means for substantially a universal use of the grab. In the first place the lighter or boat, coal or material, and the coalhandling devices, whether usable for loading a Vessel or discharging coal or material from it, are movable or transportable together from one position to another, and this enables the lighter to be loaded at any place by its own loading devices, which are also discharging devices to carry its cargo or load and loading and discharging devices to one or more ves- -sels or points of discharge and to there immediately discharge its contents by its own discharging devices, which were before used in loading it. It will further be seen that in its own loading and its own discharging it has universal range of operation, because in the irst place its position may be varied at will, as it is simply necessary to move the lighter in the water to any desired point, and in the second place that the loading or discharging devices themselves permit coal or materialto be taken on or discharged at will at either side of the lighter or at both sides alternately and to or from any reasonable distance from the lighter and over an intervening vessel or obstruction, if neces'ssary, and at any desirable height, andnot only this, but the contents of one vessel or pile of material may be transported by the grab across its own lighter or vessel to another vessel or pile without discharging into the lighter and just as readily as though the material were being loaded into or taken from its own hold. It will further be seen that by reason of the lateral openings in the tower the hoisting and traveling operation can go on at the same time. For example, when unloading from the lighter which carries the tower, as soon as the grab has been hoisted to a point where it clears the base of the tower the trolley can be moved laterally while a further hoisting operation is taking place, so that the grab from that point on will move in a curved line to its highest point without the interference of any cross-timbers. Thus the work of loading and unloading can be accomplished in much less time than where a grab has to be first hoisted to its highest point and then caused to travel laterally to a position over the point where the load is to be delivered. It will be desirable to always weigh the grab and its contents when thev grab has reached a given height, because the weight of the grab and its ropes will then be known, and the weight can be definitely tixed, and this will insure an accuracy which would not otherwise be easily obtainable. I would further remark that I do not confine the use of the portion of the apparatus comprising the central or fixed boom and the movable extension or extensions and the means for making-themoperative in part or in whole to lighters or vessels, as they may be used on shore and in connection with fixed or movable supports.

While I have shown the grab as operated by two ropes-one for hoisting and lowering it and the other for closing and opening itand while the rope-guides and weighing devices are represented as adapted for two ropes, I would say that it is not always necessary to use the two ropes and that when one rope only is employed to compel the operating of the grab or for hoisting and lowering it only one of the guide-ropes and one of the pulleys may be dispensed with, and where in the claims I have used the larger number I would be understood as also meaning to include the smaller number.

In order that the material-handling devices may move lengthwise the boom extensions or either of them without foulingv with the stay and topping-lift of the extension upon which it may be movable, I have caused the stay, which I have lettered es, to be split or made in two parts extending from a common eye at the top of lthe tower to each side of the boom extension at its outer end. The topping-lift e9 is also split into the sections m m. The section m passes upward over the sheave m2, then downward under the sheave m3, and then outward to the tackle m4. The section m passes upward to the sheave m5, then downward under the sheave m6, and then over the sheave m7 to the tackle m4. (See Fig. 11.)

It will be seen that by this construction the parts of the topping-lift are separated or held away from the path of the grab, trolley, and

TOO

IIO

IIS

operating-ropes which are movable with the trolley between them.

It will be noted that owing to the comparative height of the boom-section above the base of the tower it is possible in this apparatus, as in no other of which I have knowledge, to start and continuously operate the hoisting of the grab and simultaneously operate the trolley, say, from one eudof the boom to the other, the only restriction being that the grab shall be sufficiently high to clear the base of the tower when it reaches the base. The importance of this feature of my invention cannot be disregarded, for itis evident that this possibility will in nearly all cases save a very large amount of timein the loading or unloading of a vessel with coal or other portable material of like character, and should the structure be used upon land it will afford a similar saving of time. While this feature is due, as is stated above, primarily to the height of the boom-section of the tower above its base, it is also somewhat dependent upon the length of the projecting sections in relation to said tower-section and also upon the fact that there is a clear passage atforded below the boom of considerable height to allow the grab to move freely in either direction.

An essential part of my invention is that which relates to the height at which the boom is carried or supported by the tower and that which relates to the construction of the tower, whereby at the point Where the boom crosses the tower there is provided an unobstructed space of such height that the grab may `be moved vertically therein while the trolley is crossing it horizontally and without modifying the rate of movement of either and whereby the grab takes the same inclined or diagonal course across the tower that it has heretofore taken upon a boom located at one side only of a tower or support.

I am aware that structures have been patented in which a space slightly exceeding the height of a grab and trolley has been arranged beneath the boom Where it passes a support in which the trolley and grab may both be moved horizontally for the purpose of transferring the grab from a boom-section on one side of the support to a boom-section on the other. Such a structure is described and claimed in my Patent No. 602,726, and I do not herein claim it, one object of my present invention being to permit the load to be lifted by the grab to a variable height of delivery at any point within the ends of a boom extending across a tower and by thejoint aetion of a horizontally-movable trolley and vertically-movable grab simultaneously actuated to cause the grab to take an inclined or diagonal path from loading position at one side of the tower to a delivery-point on the other side and without being impeded by the 3 towel.

Having thus fully described my invention,
