To all 107mm t may concern.'

Be it knoWn that I, DANIEL DARROW, a citizen of the United States of America, and residing in the city, county and State of Nev.' York, have invented a certain new and Improved Barge- Conveyer7 of which the following is a speciication.

My invention relates to barges, particularly brick barges. and the object of my invention is to provide a conveyer to facilitate and expedite the loading and unloading operations on brick barges.

Referring to the accompanying drawings,

Figure 1 is a broken transverse section through a brick barge and conveyer;

F ig. 2 is a broken plan of portion of the barge and conveyer; and

Fig. 3 is a side elevation of the barge partially broken away and showing the conveyer in end elevation.

The brick barges in general use comprise fiat bottom scoivs having a flat deck on which the load of bric rs is carried. In loading such a barge, the customary practice heretofore followed has been to form piles of brick starting at opposite ends of the barge and approaching the middle of the latter from each end simultaneously or alternately at opposite ends so as to maintain the barge in trim. When the barge is fully loaded a mid passageway between the two piles is left open to permit the unloading operation to proceed in the reverse direction, viz., by removing portions of the piles at each end simultaneously, or first one and then the other, so as to prevent the barge becoming overvveighted at either end.

To load a barge has necessitated heretofore a crew of men comprising a group on board the barge, another group on the loading pier, and frequent-ly a third group Which receives the bricks from one group and passes them on to the other. When the loading pier is considerably above the barge deck'` as occurs at low tide, it not infrequently happens that a fourth group of intermediate handlers is necessary to form a complete loading or unloading crew. The bricks are ordinarily passed several at a time in What is called a hand of brick comprising six or seven bricks arranged sideJ by side and handled as a unit. The loading and unloading operation by hand in this fashion is slow and expensive and is attended by since trucks Waiting to be loaded from the barge lose from twenty-five to thirty minutes during the loading operation. Since several loads are carried during the day, it is obvious that as much as a couple of hours may be lost by a single truck standing idle during the successive loading operations thereof.

To overcome these losses I have provided a traveling conveyer mounted transversely on the barge and movable from one end to the other of the latter for handling the bricks expeditiously on both loading and unloading operations.

In the accompanying drawings the barge 10 is of the usual fiat bottom construction having a deck 11, with marginal stringers 12, Within which the deck load of brick is carried. J ust inside the longitudinal stringers, on opposite sides of the barge, I have provided guide channels 13 and 14 in which run the supporting Wheels 15 and 16 at opposite ends of the trame 17 of a traveling conveyer. Intermediate legs 18 and 19 with rollers 2O and 21 bearing freely upon the deck of the barge may be provided to support the Weight of the frame. A mast 22 is provided at one end of the conveyer frame and is supported bv lateral struts 23 and 24 and longitudinal struts 25.

The conveyer proper comprises a pair of endless chains 26 and 27 between which eX- tend contiguous supporting slats 28 provided at intervals with cleats 29 spaced apart a slightly great-er distance than that oceupied by a hand of brick 30. These chains pass around sprocket Wheels 31 and 32 on a shaft 33, driven by an explosion engine 34 carried at one end of the conveyer frame 17. At the opposite end of the conveyer the chains pass around a drum 35 at the free end of a boom 36 pivoted at 37 to the longitudinal beams of the frame 17. lThe boom 36 may be raised or lowered by cables 38 passing from their point of attachment 39 over pulleys 40 at the head of .the mast 22 and thence to Winding drums 41 operated through gears 42 and 43 and hand crank 44. If desired, a counter mechanism 450 may mounted on the boom 36 in such position that it is actuated by successive hands. of brick thus adording a record of the number of brick piled on or discharged from the barge.

The motor 34 is mounted at one end of the frame and preferably aligned with the latter so as to take up as little room as possible lengthwise of the barge thus economzing
