BARGE CARGO SHIP 2 Sheets-Sheet 2 Filed Aug. 9, 1957 2,988,036 BARGE CARGO SHIP Roy Earl Mooneyhan, P.-0. Box 54, Reddmg, Conn, and Castle Barnard Mooneyhan, Rte. 2, Sumter, S.C. Filed Aug. 9, 1957, 'Ser. No. 677,268 4 Claims. (Cl. 114-72) The present invention relates to a barge cargo ship, particularly for the transportation of a large number of cargo containing units in the form of floatable barges, an object of the invention being to provide an integrated arrangement of ship structure, barge units, and transfer facilities for loading and unloading the barge unlts, whereby the maximum cargo carrying capacity of the ship may be realized, and it becomes possible to efficiently load and unload the ship under widely varying conditions. In particular the invention makes possible the loading and unloading of the ship either at dock side or in open water, the floatable barge units being capable of being towed, as by tugs, between the ship and any shoreline or up-river point of supply or delivery.

A further object is to provide a barge cargo ship suited to the needs of both commercial and military use, it being possible in either case to transfer cargo under normal conditions, as well as in areas where harbor or dock facilities are non-existent or have been destroyed.

Another object is to provide a cargo barge ship in which the barge units may be selectively and independently transferred from the ship Without regard to their location in the ship.

Other objects and advantages of the invention will become apparent from a consideration of the following detailed description taken in connection with the accompanying drawings wherein sitisfactory embodiments of the invention are shown. However, it is to be understood that the invention is not limited to the details disclosed but includes all such variations and modifications as fall within the spirit of the invention and the scope of the appended claims.

Referring to the drawings, the barge cargo ship '10', ac-. cording to the exemplary embodiment of the invention, has a substantially conventional hull structure of the type commonly embodied in a self-propelled ocean-going tanker. In the bow section there are provided suitably arranged compartments, these being for instance fuel bunkers 11 and 12, fresh water tank 13, chain locker i4, fore peak tank 15, bosuns stores 16. The stern section is also provided with suitably arranged compartments, for instance an engine room 17, machine room 18, and fresh water tank 19.

Between the bow and stem sections the major portion of the hull is in the form of a hold divided by bulkhead partitions 20 extending longitudinally and transversely into a plurality of watertight compartments 21 for receiving the cargo barges, these compartments being open at their upper sides with their upper edges in a plane flush with a stem or ship end deck 22 extending over the engine room.

A superstructure 23 having a top wall or roof deck and longitudinal side walls extends over the barge rereiving compartments and the stern deck 22 to the stern of the ship and constitutes an enclosed barge transfer tunnel 24 extending substantially the full length of the ship, and which is adapted, as will presently more fully appear, for the transport of the cargo barge units to. and from the compartments.

Upon the underside of the top wall of the transfer tunnel there are secured tracks 25 which extend longitudinally in parallel relation to the longitudinal side walls of the compartments and which are connected through suitable switches and convergent track sections 26 to a pair of centrally arranged tracks 27 provided above the stern deck 22. In the illustrated example of the invention the egg type crate arrangement of the barge receiving compartments provides three longitudinal rows of compartments and four tracks are provided above their side walls so that each row has a double overhead track extending along its sides for the transport of overhead barge carrying cranes moving through the tunnel, as will presently more fully appear.

In addition to providing an all-weather protection for the hold of theship and a support for the transfer tracks, the transfer tunnel supports upon its top wall-or roof deck quarters for the ships company, these being illustrated as oificers quarters 28, wheel house 29, radio and chart room 30, and crews quarters 31.

The stern end of the transfer tunnel has a door opening 32 which may normally be closed by a watertight door 33, as seen in FIG. 8, and within the stem end of the transfer tunnel there is provided a retractable barge handling rig 34, which normally is retracted within the ship, as seen in FIG. 8, and, when loading and unloading operations are in progress, is projected through the doorway, as seen. in FIG. 6, to provide for the raising or lowering of the cargo barges, which are adapted to be floated into position at the stern of the ship beneath the projected rig.

The rig 34 is of conventional steel beam bridge construction, and consists of a pair. of side members 35 and 36 connected at their upper sides by transverse beams 37, upon which there are supported a pair of tracks 38, adapted in the projected position of the rig to be aligned with the pair of tracks 27 so thatthey form a continuation theerof. Suitable rollers 39 are provided upon the sides 35 and 36 for convenient projecting and retracting movements of the rig upon the stern deck 23, and the height of the rig is such that it may be raised in the projected position as seen in FIG. 6 to align the tracks 38 with tracks 27, and may be lowered to engage the maybe propelled by any members 35 and 36, and in the projected position of the rig these serve to firmly engage the upper side of the rig against the under side of the top wall of the tunnel 24 to thus rigidly support the rig.

The transfer crane 41 is in the form of. a rectangular frame suitably formed of steel beams, and is provided at its four corners with U-shaped hangers 42 each of which is provided at its upper end with a pair of rollers 43 adapted to engage the track. The track is of I-beam form in cross section, so that the rollers rest upon its lower horizontal section at each side of its vertical sectron.

Also at each of the four corners there is provided a suspension cable 44 for connection to a corner of a cargo barge, as will presently more fully appear, each of these cables being carried over pulleys 45 and 46 to a common winding drum 47 supported upon a centrally disposed platform section 48 of the crane, and which may be either manually operated or driven through suitable gearing by an electric motor 49 or other suitable motive power.

The floatable barge 50' is of rectangular box like form open at its upper side, and is adapted to' have its open upper side normally closed by a watertight cover 50a. Suitable eye-bolts or the like 51 are provided at the four corners for attachment of the cables 44 of the transfer crane 14. Preferably the barge is provided with an inner bottom 52 provided with suitable elevating mechanism, this mechanism being illustrated as a plurality of vertical screws 53 respectively engaged with suitable nuts -4 of the inner bottom, and respectively provided at their upper ends with worm gears 55 engaged by a series of worms 56 provided upon a pair of longitudinally extending shafts 57 arranged along the longitudinal sides of the barge. The shafts 57 are respectively provided at one end with worm gears 58 engaged by worms 59 provided upon the ends of a drive shaft 60 extending transversely at one end of the barge, this shaft being driven either by a suitable motor 61. or by manual means.

In operation, the elevating screws are turned simultaneously and equally to raise or lower the inner bottom 52. When loading or unloading the inner bottom is raised so that it is substantially flush with the upper side of the barge and the cargo 62 may be loaded or unloaded by fork lift trucks or other suitable means. As shown in FIG. 11 at the upper right hand corner the barges are tied to a dock 63, and fork lift trucks 64 are shown in the process of transporting cargo to or from the barges. It will be understood that other methods of loading and unloading'the cargo may be resorted to and the cargo barges may under certain circumstances be transported from the water to suitable transportation vehicles for transport over land. Also the cargo barges may be adapted for amphibious use by providing them with retractable wheels so that they are capable of being either floated on water or rolled over land.

\ transferred to or from any one of the compartments In the illustration two barges are fitted into each compartment. However, it will be understood that under certain requirements a single barge may be designed to fit one compartment, while under certain other requirements more than two barges may be fitted into one compartment. The several track ways extending respectively over the several rows of barge receiving compartments enables the use of several cranes, so while one crane is operating at the rig, the other cranes may be moving to and fro along the several rows of compartments. A particular advantage of the overhead tunnel is that a barge may be I without interference with or the necessity for moving other loaded barges to make way for. the barge being transferred.
