To all whom it may concern.-

' Be it known that I,'MICHAEL S. IVERSON,

a citizen of the United States, residing at New York, in the county of Kings and State of New York, have invented certain new and accompanying and forming part of the same.

This invention relates generally to conveyers and elevators, and particularly to floating elevators or lighters; and its object is-to provide simple and efiicient means for dischargin a cargo of grain or other loose material.

lily invention consists in certain combinations of -devices, features of construction, and arrangements of parts, all as will be hereinafter set forth, and particularly pointed out in the claims.

a side elevation of a lig ter built according to my improvements, the hull being shown in longitudinal section. tion of the. hull. Fig. 3 1s a detail showing one form ofweighing means which may be placed at the bottom of a bucket-shaft. Fig. 4'is a plan of the bins and elevator-shafts in the hold of the lighter. Fig. 5 is a side elevation of a band conveyer. Fig. 6 is a plan of a strip of flooring running along the middle ortion of the li hter and beneath which the ower reach of llifiahim conveyer runs, said view showing independently-operable gates in the floor over the buckets of the conveyor.

Fig. 7 is a sectionof Y the lower reach of, the band conveyer, showing the relative arrangement of the buckets. Fig. 8 is a-section on line VIII VIII, Fig. 5. Fig. 9 is a section online IX IX, Fig. 5. Fig.,1 0is a plan view of a sectionof thelower reach of the band, showing one form of sprocket-chain which may be used therein. Fig. 11 is a front elevation of the superstructure of one of the elevators seen at Fig. 1. Fig. 12 is a side elevation of a gate for closing a chute that receives discharge irom the upper reach of the band conveyer. Fig.13 1s a diagrammatic detail of" means-for tilting a floor-leaf rovided in a bin; whereby the grain may e shifted toward the conveyor.

In the several views like parts are identiiied by like signs.

At Fig. .5 is illustrated the preferred formof a band conveyer, which comprises an endless chain 1, a pair of wheels 2- 3', over which Fi 2 is a cross-sec-' and the latter having sprockets 4- to drive the chain and buckets 5, connected to the chain. The band comprises an upper reach 6 and a lower reach 7. In the latter the buckets are in normal condition, or open at'the top, to receive the grain or material to be conveyed,- while in travelingup over the wheel 2 the buckets become inverted, and hence. capable of discharging their contents. The lower reach of the conveyor runs upon rolls 8, suitably mounted upon the bottom of floor-90f the lighter, and overlying said lower reach is an upper strip of flooring 10, extending longitudinally of the lighter and at about its middle portion, said strip 10 cooperating with the rollers 8 to guide the lower reach 7, thereby preventing the buckets from shaking ,out their contents. The grain carried in the lighter discharges through apertures 11, formed in said strip, into the buckets 5 in the lower reach. To prevent spilling the mate.- rial'from the buckets after they are filled and before the point of discharge is reached, an en dless belt 12 runs over the Wheel 2 and directly in contact with the wheel-rim, thus occupying a position between the buckets and the wheel, so as to close the mouths of the former. The belt is sufficiently narrow to lie between the inner links 13, Fig. 5, of the chain 1, completely covering the buckets, so that the contents thereof cannot escape. From the top of the wheel 2 the belt 12 runs partly along the upper reach 6 of the band conve er and in contact with the buckets, still eeping them closed, as at 14, Fig. 5, and at a point about midway between the

wheels

2 and 3 the belt runs down around an idle pulle 15,

and thence directly back and finally own'.

over an idle pulley 16 to the wheel 2. Beneath the return portion of the belt is a guard or partition 17, which closes in the belt and sprocket-wheel 3 and thence down' to the- IIO lower reach 7 to become refilled. U on both the chain runs, the former being an idle wheel I sides of said chute the upper reac. is sup ported by suitable rolls 21, located above the partitions 17 and 19, and a guard or partition 4 22 overlies the upper reach and extends either into a chute upon the other side of the lighter.

down aroundthe wheels 2 3, as at '23, to the floor 9 of the lighter. The overlying strip 22 may be flush with or form part of the deck of The-chute'or well 20 is provided at 'each side with a spout or discharge v23, having a ate 24, which may be lifted by a Buckets 27 receive the discharges from said s outs and preferablyrest upon platforms 28 of scales 29,

Fig. 3,.whereby the weight of the contents of each bucket may be ascertained. Said Tplatforms are at the lower portions of shafts 30,- one at each side of the band conveyer alreadydescribed, and may be hoisted up said shafts by means of ropes 31, connected to any suitable winding means.

. One of the hoisting-buckets may dump into a chute 32, shown near'the top of a superstructure 33, rising-from the deck 34 .of the lighter, while theother bucket may dump the superstructure or else may be hoisted farther and dumped into a chute 36, which is supported above the-chute 32 and on the Y same side of the lighten Hence the lighter ma discharge from both sides simultaneous y or ma discharge all at one side, as may be require Each dumping-chute is rovided with a movable spout 37, adjustab e to '44, carried by the lower end of'a vertical shaft 45, whose upper end isprovided with a hand-wheel 46 above the deck 34 of the lighter, whereby any gate may be 0" ened or closed conveniently and independent y of the other gates. As seen at Fig. 4, the hold may be divided on each side by a series of parti tion's 47, which are a convenience in connection with the gates 42 in keeping the-lighter in proper trim as well as being otherwise desirable.

Upon the floor of each bin or compartment lies a leaf 48, Figs. 2 and 13, hinged at its lower edge at 49, so that it may be tilted up tourge or shift the material toward the band conveyer. The upper ed e of the leaf lies normally under a hinged dap 50, which revents material from dropping into the b1 ge, said flap bein caught by a latch 51 when it is lifted by the eaf. The latter is operable by means of a series of arms 52 depending from its under side and connected b a chain or chains .-53 to a shaft-like win ass 54, the
