SPECIFICATION formingpari; of Letters Patent No. 742,101, dated October 20, 1903. Applicatieuiled February 19. 1902. Serial No. 94,749. (No model.)

To all whom it may concern:

Beit known that I, GEORGE E. TrTcoMB, a citizen of the United States, residingin Philadelphia, Pennsylvania,V have invented certain Improvements in Barges, of which the follovv-` ing is a specification. i r

The object o f my invention is to provide barge for carrying coal'or other material with suitable discharge mechanism, "so that the barge can discharge its ownload, the mechanism being so designed andarranged that the crew of the barge can readily attend to the discharge mechanism when the barge is at a Wharf or alongside another vessel.

The Wharves of large cities or ports are usually supplied with cranes 'or other discharge mechanism for handling coal or other material to readily discharge a bargeat the wharf;

but at other points Where coal is delivered atintervals-say at small Seaportsthere is no mechanism upon the Wharf for the proper handling of the coal, and in these ports coalbarges only arrive at long intervals, so that the expense of equipping a Wharf with proper coal-handling mechanism would be too great to Warrant the outlay. I-Ieretofore at these Wharves the coal orl othervmaterial has been discharged from the barges by manual labor, the stevedores shoveling thecoal into buckets or bags and carrying them out of the hold to the wharf. In many instances barges have been delayed owing to the fact that manual labor at these ports is very scarce, as it would not be feasible to employ the stevedores on the wharves all the time, and when the vessel arrives a delay of several days is often necessary before the proper number of men can be obtained to discharge the vessel.

I overcome all the above objections by equipping the barge with its own coal`handling mechanism, and so arrange this coalhandling mechanism that the crew of the barge can attend to the discharge of the coal from the lvessel to the Wharf Without the aid of additional help at the Wharf.

In the accompanying drawings, Figure lis a plan View of a barge, illustrating my invention. Fig. 2 is a longitudinal sectional View.

Fig. 3 is a transverse sectional view showing the boom e'xtended. Fig. 4 is a view similar to Fig., 3, showing the boom, lashed to the mast and out of action; and Fig. 5 is a view of adetail of my invention.`

A is a barge of any ordinary type, in the present instance having the engine or other propelling means at the stern, the balance of the vessel being taken up in storage-bins for coal or other material. The bins in the present instance are numbered l, 2, 3,- 4, 5, and 6 and are so proportioned as to properly balance the load.

B, B', B2, B3, and B4 are the masts, Which are suitably guyed and'connected together by ropes b.

a, a2, a3, a4, a5, a6, @Zand a8 are the hatchways for the severalbins.

D, D', D2, D3, D4, and D5 are the booms upon whichthe discharge mechanism travels. Each of these booms is pivoted to a block d, swiveled in a slide d', arranged to travel on suitable rails d2, secured to the deck a of the vessel, as shown clearly in Fig. 3. The booms alternate with the masts, and the slides d can move on the rails d2 toward either mast and can be raised or lowered or turned laterally on the pivots, as desired. The booms are made,preferab1y,ofchanuel-bars,so as to form rails on which the trolleys E can travel.

e indicates the hoisting-ropes, which pass around pulleys c at thel outer end of the boom and pulleys e2 near the pivot to the hoistingengine F. In the hoisting mechanism illustrated two hoisting-ropes are used, each secured by one of its ends to the trolley, so that when the'bucket has been closed and elevated in'contact With the trolley-by hauling on both cables a continuation of their movement will cause the trolley and bucket to travel in combination up along the inclined boom, clearing the hatch-coamings and moving to the out-portV end, so as to b e beyond the side of the vessel. The advantage of this arrangement is that the operations of closing andfelevating the bucket'and traversing it alongthe boom can be effected by the uninterruptedV continuous rotation of a single shaft w'ith suitable rope drums and clutches or the like,

the inclination of the jib or boom insuring that the vertical lift of the bucket shall be completed prior to the commencement of the lateral travel. When the bucket has completed its lateral travels, it can be opened by simply slacking one of the two cables which were previously operated together to elevate it. If it should beldesired that the bucket be lowered before being opened, this can be eiected by slacking away both cables, the trolley being prevented from traveling along the boom by a suitable stop. The buckets may be discharged into a movable hopper G, (shown by dotted lines in Fig. 3,) and this hopper can discharge the coal into cars on tracksg on one side ofthe hopper, (also shown by dotted lines in Fig. 3,) or the material can be discharged directly onto the wharf or into cars when desired or other vessels or lighters when necessary.

The boom is supported in its extended position by guy-ropes c, which are operated in the present instance by means of a hoistingengine F", (shown in diagram,) and this rope extends from one mast to another. After the unloading of the vessel is accomplished the boom can be elevated to the position shown in Fig. 4L and moved toward the mast, where it is lashed, so that while the vessel is on a voyage it will be securely held in position, the bucket being first removed and the trolley being lowered to the position shown in Fig. a.

Thus it will be seen that I provide a numbei' of independentlybperated hoisting mechanisms (six in the present instance) each provided with a hoisting-engine, boom, and bucket, so that the crew can readily handle the said mechanism. It' there is a crew of six men, for instance, each man can operate a single hoisting mechanism. Bythis means the load of the vessel is gradually reduced without trimming one part ot' the load more than another, and by providing a number of hoisting mechanisms,as shown, the vessel can be very quickly unloaded, and thus save considerable time in the transportation of material from one port to another.

I claim as my inventionl. The combination of a vessel, a mast, a rail on the deck of the vessel, a slide adjustable on the rail, a block swiveled in the slide, and a boom pivoted to the blpck and guyed to the mast, with hoisting mechanism carried by the boom, substantially as described.

2. The combination of a vessel, a series of masts on the vessel, hatchways between the masts, one or more rails on the vessel, a series of slides mounted on the rails, a series of booms alternating with the masts and pivoted to the slides, said booms being guyed to the masts and each boom having a trolley and a bucket and hoisting mechanism, substantially as described.

3. The combination of a vessel having a hatchway, a mast, a rail on the deck at one side of the hatchway, a slide adapted to travel on the rail, a boom pivoted to the slide and extending over the hatchway to the opposite side of the vessel, said boom being guyed to the mast, and hoisting mechanism carried by the boom, substantially as described.

4. The combination of a vessel, a hatchway,'two masts, one on each side of the hatchway, a rail on one' side of the vessel, a slide arranged to travel on the rail, a block swiveled to the slide, a boom pivoted to the block and guyed from the two masts so as to eX- tend over the hatchway and over the opposite side of the vessel, a trolley on the boom, a bucket, and means for raising and lowering the bucket and traversing the trolley, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE E. TITCOMB.
