3 Claims. 1

This invention comprises apparatus and method for cargo handling to facilitate the removal of cargo from a boat or ships hold and to transfer it to a dock or pier as well as to lift cargo from a dock and deposit it in a hold of a ship with a minimum expenditure of time and labor.

Other objects of this invention are to provide apparatus, a part of which is superposed over a ships hold and suitably anchored to positively, prevent displacement during the unloading or loading cycles, the apparatus being adjustable to conform to the size and contour of the hold; to include in the apparatus a monorail for carrying a powdered or manually operated hoist dolly, the monorail being equipped with safety devices to prevent movement of the dolly beyond predetermined rail limits; to provide means for permitting independent adjustment of the monorail; and to provide apparatus constructed in accordance with the teaching of this invention, which may be placed in position over and removed by the ships crane without the use of extraneous mechanism.

A further object of the invention is to provide a method for loading and unloading ships wherein a monorail rig is superposed over the ships hold, the monorail extending transversely of the ship in order to transport the ships cargo over the side of the ship for transference to a pier-carried monorail which preferably extends at right angles to the ship-carried monorail, the monorail on the pier being equipped with cargo transporting apparatus.

Other objects of the invention will be apparent from the following description of the present proferred form of the invention taken in connection with the accompanying drawings, wherein:

Figure l is a perspective view of an apparatus for cargo handling constructed in accordance with the present invention illustrating its application to a boat and adjacent pier;

Figure 2 is a detail enlarged fragmentary top plan view of a frame joint as employed in the present invention;

Figure 3 is a transverse sectional view of the same taken on the line 3;--3 of Figure 2;

Figure 4 is a detail fragmentary perspective view of the connection clamp for the rig frame and a rig carried monorail; and

Figure 5 is a detail fragmentary perspective view of one of the rig carried anchoring straps illustrating its application to the boat.

In order to illustrate the application of this invention, a boat 6 is shown in Figure 1 of the drawings which includes a hold I, the passageway or alley to which is indicated at 8. Figure 1 also, for purposes of illustrating the application of the invention, shows a pier 9 which runs in parallel relation to the boat 6 and is equipped with a monorail [0 supported by stanchions H. The monorail carries apparatus generally designated l2 for transporting cargo on the pier in an obvious manner.

The apparatus of the present invention includes a rig generally designated l3, the rig in the present instance consisting of a rectangular skeleton extensible frame l4 supported on deck caried standards IE. The frame, composed of interengageable beams, is provided at each side and at each end with a joint 16 which permits telescopic connection of adjacent parts of the frame. The joint includes bolts I1 and jam nuts it to secure the adjacent slidable terminals of the frame parts together as illustrated advantageously in Figures 2 and 3.

The rig I3 is adapted to be anchored on the deck of the boat 6 immediately over the hold I and for this purpose clamping straps l9 are employed. Two straps L) are employed, one being engaged with each of the two parallel standards P5. The upper end of each strap is secured to its standard, as indicated at 29. At a point just below the locus of securement, the strap is bent outwardly, as indicated at 2|, and the strap continues downwardly to a point appreciably below the bottom of the standard 15 and correspondingly below the alley 8 on the inside of the latter. The lower end of each strap is bifurcated, as indicated at 22, the branches of the bifurcation straddling a bolt 23 which extends from and is carried by a permanent part 24 of the deck. of the boat. By this arrangement, as advantageously illustrated in Figure 5, the rig is positively secured from casual displacement at the side of the rig opposite to that over which or beyond which the cargo is transported. In order to support transporting means for the boats cargo, a boat monorail 25 is employed, the monorail being pendently carried by the frame of the rig l3. In order to clamp the monorail to the frame, a suitable clamping assembly, generally designated 26, is used. Each of the clamps includes twin base plates 21, the inner ends of which are offset to provide flanges 28 which are slidable beneath the top run of the monorail 25. One terminal of each of the base plates is reduced and bent upwardly at right angles to provide a lug 29 which is adapted to embrace the inner face of the frame portion of the rig [3 as shown in Figure l. The clamping assembly 26 also includes a spanner plate 30 which extends across the plates 21 above the depressed flanges 23. The plate 30 has superposed thereon a key plate 3| the latter, in conjunction with the spanner plate 311, being secured to the base plates 21 by bolts 32. The clamping assembly 25 is detachably secured, through the medium of the bolts 32 to the monorail 25 and parallel sides of the frame M.

The monorail 25 is equipped with cargo handling apparatus generally designated 33 which may support cargo 34 as shown in Figure 1. The monorail .25 is of a length to permit the free end thereof to span the distance between the boat 6 and pier 9, the free terminal preferably overlapping an intermediate portion of the pier carried monorail [0. By this arrangement cargo removed from the ships hold is transported over the side of the boat to the pier and manually transferred from the boat carried cargo handling apparatus 33 to the pier carried cargo handling apparatus [2. The reverse procedure is followed when loading the boat.

In accordance with the teaching of the present invention, a rig of very simple construction may be positioned in close proximity to the alley or ships hold by the ships crane. The frame may be expanded or contracted to adjust the rig to the dimensions of the alley. Correspondingly, the frame may be anchored to the deck of the boat at one side of the alley in a manner already herein described. In view of the complete adjustability of the rig it adapts itself for any dimensional variation. The rig is positively anchored to the deck and if desired, its standards 15 may have pressure plates 35 inserted therebetween and the deck. When not in use, the rig may be dismanteled and stored in a relatively small place.

Although a preferred apparatus and method is shown and described herein, weare aware that various changes may be made within. the scope of the claims hereto appended.

What we claim is:

1. In combination with a ship including a deck with an alley leading to the ships hold, apparatus to facilitate lifting of cargo from the hold and lowering cargo into the latter comprising a rig mounted on th deck, the rig embodying supporting standards positioned around said alley, a pair of straps, one engaged with each of the standards at one side of the rig, the lower ends of the straps being laterally offset for sliding engagement over the ships alley and bifurcated at a point ap- 4 preciably below the top of the latter and means secured to a permanent part of the deck for engagement with each bifurcation to prevent casual displacement at the side of the rig opposite to that over which or beyond which the cargo is transported.

2. A device for handling ships cargo comprising a rig adapted to be anchored on the deck of the ship above the ships hold, the rig comprising a rectangular extensible frame, each side of the frame including a joint, means for securing the joint to prevent relative movement of the frame parts, the rig also including vertical standards which pend from the corners of the frame and are engaged with the ships deck adjacent the hold, a strap engaged with each of two parallel standards, the lower ends of the straps extending into the ships hold and secured to a permanent part of the deck of the ship to prevent casual displacement of the rig, and a monorail one end of which is secured to the undersurface of the rectangular frame, the opposite end projecting beyond the side of the ship, said monorail being adapted for the transportation of cargo to and standards positioned around said alley, ex-

tensible beams mounted on the standards and spanning the latter, means for transporting cargo to and from the rig including a monorail carrier, and a clamp assembly for securing the monorail to a, parallel pair of said beams, said assembly permitting a sliding movement of the monorail therein when the beams are extended in the direction of the monorail.
