DUMPING SCOW.

SPECIFICATION forming part of Letters Patent No. 678,657, dated July 16, 1901.

Application filed January 21, 1901. Serial No. 44,092. (No model.)

To ctZZ whom it may concern.-

Be it known that I, J OHN Mnnsron Goon- WIN, a citizen of the United'States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Dumping Scow or Vehicle, of which the following is a full, clear, and exact description.

This invention relates to improvements in dumping scows, vessels, vehicles, bins, wagons, or the like; and the object is to provide a device of this character with a simple means for causing the discharge or unloading of the scow, vessel, or the like which will not careen, and which has cargo-carrying compartments substantially \l-shaped in cross-section.

I will describe a dumping-scow embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is an end elevation of a dumpingscow embodying my invention. Fig. 2 is a top plan view. Fig. 3 is a cross-section of a vessel embodying my invention. Fig. 4 is a partial side elevation thereof. Fig. 5 is a side view of a detent employed. Fig. 6 is a cross-section of a portion of the vessel, showing methods of supporting the discharging and replacing devices. Fig. 7 is a side view of a device for supporting one side of the side valves and swinging the same when discharging. Fig. 8 is a top plan view of detents, a detent-shaft, counterweights, and showing methods of attaching same to the bulkheads. Fig. 9 shows side elevations and top views of a replacing-hook employed, and Fig. 10 shows top and side views of a replacing-link employed.

The dumping-scow comprises a body portion 1, divided by vertical partitions 2 into a series of independent compartments, the

bottoms of all these compartments being inclined downward, and each bottom comprises one or more center valves 3 and downwardlyswinging side valves l. The upper edges of the side valves are connected to the vertical side pieces 5 of the body by means of barhinges 6, and, as shown in the drawings, Fig. 7, two bar-hinges 6 are arranged together,

or, in other words, the hinges are arranged in pairs, mounted to swing on a longitudinally-extended bar or hoisting-shaft 7. The two hinge-sections are connected at the lower end by a pivot-pin 8, which passes through a keeper 9, attached to the outer side of the valve l.

As here shown, the body is supported on two scows or vessels 10, there being a space between these vessels through which the cargo may be discharged, as will be hereinafter described. It is to be understood, however, that while I have shown the body as mounted on scows it may be mounted on stationary supports or on wheels.

The center valves 3 are connected to V- shaped struts 11, which at their lower ends or apexes are provided with rollers 12. These struts are mounted to swing on a rod 13, extended longitudinally through the body and at the lower portion thereof, and extend ed lengthwise of the body underneath the 'rod 13 and laterally thereof are center-valvereleasing shafts 14. Connected to these shafts 14 are detents 15. These detents have curved bearing-surfaces, the sides of which are provided with flanges to prevent lateral movement thereof in relation to the rollers 12, which are extended to bear upon the curved surfaces of these detents. The several detents on a shaft or rod. 14 are of varying widths-that is, the detents for the second compartment will have a bearing-surface twice that of the detents for the first compartment, and the detents carrying the cen-' ter valve of the third compartment will have a bearing-surface three times that of the first compartment, and so on throughout all the compartments there may be in the body. This is to provide for unloading the several compartments one after the other-that is, by rotating the shafts 14 all the detents will be moved; but all of them except the first will remain in engagement with their rollers 12, while the first ones become disengaged from their rollers, allowing the center valves and side valves to fall. It will be noted that the inner or free edges of the side valves when in closed position rest upon the outer edges of the center valves. After discharging the first compartment the shafts are to be still further turned to release the valves of the second compartment, and so on until all the compartments are discharged. I will state here that while the above description might indicate that the valves of both sides are operated together, it is to be understood that the valves of one side only may be opened, while the others remain closed, depending upon the side of the vessel from which the load is to be discharged, or, as will hereinafter appear, the load may be discharged between the two scows or vessels 10.

Arranged at opposite sides of the body portion are short chutes 16, and to these short chutes auxiliary chutes 17 are hinged so that they maybe swung upward against the body when not in use. WVhen in use, however, these swingiiig chutes 17 will be lowered, as indicated at the right-hand side of Fig. 3, so that the load will discharge over the same. In the upper portion of each fixed chute is mounted to swing a retarding valve or plate 17 This retarding-plate has its end walls pivoted to the sides of the chute 16, and its front plate may be lowered more or less into the discharging material.

Arranged to close the space between the lower edge of a valve 3 when said valve is in its open position and the upper end of the fixed chute 16 is an auxiliary valve 18. This auxiliary valve 18 is made in the form of a plate and is mounted on spring-yielding hinges 19, which swing on rods 20. These hinges not only permit the swinging of the said valves 18, but, being yielding, form buffer-abutments for engaging with the valves 4 when they are swung to their open position, as indicated at the left-hand side of Fig. 6.

When the said auxiliary valves 18 are open,

as shown at the left-hand side of Fig. 6, the material discharged will be directed between the vessels or scows 10, the said open valves 18 forming stops and directing-valves. The valves 18 are moved by hand-power to their open or closed position.

A hoisting arrangement for the purpose of replacing the center valves and side valves to carrying position consists of a hoisting-shaft 7, mounted on the side of the vessel, one movable pulley-block 22, a chain 23, connected at one end to the upper portion of a partition and extending around said pulley 22 and thence around a fixed pulley 24 and to the shaft 7, which may be turned by any suitable means. Connecting with the two divergent members of the chain 23 are hoisting-hooks 25, adapted to be by hand placed in engagement with links 26, connected to the valves. The novel formation of the hoisting-hooks 25 allows them to disengage themselves from the links 26 by gravity when the strain of hoisting is releasedthat is, each hoisting-hook has a weighted extension 27, which will rock the curved surfaces 28 of the hooks on the upper side of the valves when the hoisting strain is released, and when this strain is released the hooks will move downward until they come into engagement with the valves. Then the weighted ends will cause said hooks to swing outward out of engagement with the links 26, as it will be noted that the chain 23 is on an incline when the hooks are in their holdingposition. When the hooksare byhand placed in connection with the links and the chains drawn taut, the weighted ends of the hooks will be drawn upward, causing the forked members of the hooks to engage the inner and outer surfaces of the eyes, so as to hold tightly when lifting the valves. The links 26 are mounted to slide in openings in the valves,so that when said valves are swung to their open position the said links at their inner ends will be practically flush with the inner surfaces of the valves. By the use of the movable pulley 22 the hoisting-power be comes double that usually obtained by the use of the-fixed pulleys. Therefore it is feasible to raise both the center valves and the side valves at the same time. The branches of the chain 23 must be of such length and attached at such points to the main chain that the side valves precede the center valves just before reaching the carrying position, as indicated by the dotted lines in Fig. 6. In other words, this is to prevent the closing of the side valves before the passing of the ends thereof over the ends of the center valves while said center valves are moving to'closed position.

Attached to one end of the shafts 14 are arms 29,provided at their free ends with slots, through which a pin projecting from the vertically-operating bar 30 extends. This bar 30 is provided with a piston adapted to operate in a cylinder 31 and by means of which rocking motion may be imparted to the shafts 14. The chutes 17 may be raised and lowered by means of chains 32, and it will be noted that the outer sides of the struts 11 are provided with teeth 33, with which a crowbar or other device may be engaged to start the valves should they become frozenor otherwise tem porarily locked.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
