Patented Mar. 18, 1941 CARGO LOADING AND UNLOADING APPARATUS Lawrence Matarese, Brooklyn, N. Y. Application January 28, 1939, Serial No. 253,423

2 Claims. This invention relates to cargo loading and unloading apparatus, and has for one of its objects the production of a simple and efficient apparatus for facilitating the handling of the cargo in a manner to reduce the hazard of accidents, reduce loss occasioned by damage to the cargo, and save time in handling the cargo;

Another object of this invention is the production of a simple and eflicient means forholding the cargo while it is being hoisted.

Other objects and advantages of the present invention will appear throughout the following specification and claims.

In the drawing:

Figure 1 is a side elevational view of the hoist ing apparatus;

Figure 2 is a top plan view of the lifting platform;

Figure 3 is an edge elevational view of the lifting platform;

Figure 4 is a top plan view of the lifting bridle and bridle frame;

Figure 5 is an end elevational view of the cargo engaging mechanism of the lifting apparatus;

Figure 6 is an enlarged longitudinal sectional view of a portion of the lifting platform;

Figure 7 is a fragmentary perspective view of one of the bridle ropes and a portion of the retaining net.

By referring to the drawing, it will be noted that there is illustrated a cargo handling device or apparatus wherein the steel cargo hook 32 which is used in hoisting is shown connected to a lifting or suspending bridle 33 formed of manila or wire rope, or other flexible means, the top ends of the bridle 33 being spliced to. the ring 34 in the conventional manner. The bridle 33 is provided with depending leg portions 35, and these leg portions 35 pass through the corners of the bridle frame 36 which is preferably rectangular in shape as is shown in Figure 4. The lower ends of these leg portions 35 engage the links 37 which are carried by the transversely extending lifting bars 38.

The lifting bars 3% are adapted to fit under the respective ends of the load-carrying planks 33 which constitute a floor portion of the lifting platform Ml. Transversely extending braces ll constituting spacers are interposed between the upper series of planks 39 and the lower series of planks 42 for holding the

planks

39 and 42 in spaced relation. The lifting platform 40, the floor portion and spacers comprise a load-handling pallet which may be made of any suitable material without departing from the spirit of the invention. Retaining strips or bars 43 are secured to the under face of the u per planks 3| adjacent their outer ends and these strips 43 constitute retaining means tending to hold the lifting bars 38 against accidental displacement. 5 The retaining strips 43 are spaced from the outer edges of the lower planks 42 sufficiently to permit the lifting bars to be disengaged from the platform 40 when so desired. Under ordinary conditions, however, these lifting bars will not become accidentally displaced. A suitable mesh net 44 is carried by the depending legs 35 of the bridle 33 in the manner shown in Figures 1 and 5. The lifting or suspending bridle 33, which may be in the nature of any flexible means, such as rope or a chain, and the lifting bars 38 which may also be of any suitable material, in conjunction with the load-handling pallet, provide a load-handling device which may be placed on irregular surfaces as well as on fiat surfaces.

It will be noted by considering Figure 1 that a conventional span is employed embodying a structure beam 45 supported in a proper manner to suspend the lifting apparatus and this beam 45 carries a bolt 46 which connects a shackle 4'! thereto. This shackle ll connects a plurality of links 8 to a suitable pulley 49 over which a lifting cable 5|] passes, the cable also passing through the hook 32 and one end of the cable passing over a pulley 5! carried by a ship derrick 53 which may be raised and lowered through the medium of a cable 53 passing over a pulley 54 carried by the ship derrick 52. The opposite end of the cable or wire rope till may be anchored in any suitable or desired manner.

Certain detail changes in the mechanical construction may be employed without departing from the spirit of the invention, so long as such changes fall within the scope of the appended 40 claims.

Having described the invention, what is claimed is:

l. A lifting device of the class described comprising a flexible bridle, a guiding frame, said r flexible bridle passing through the guiding frame for holding the flexible bridle in formed relation,

a mesh net carried by the bridle, lifting bars carried by the lower ends of said bridle, a platform having a floor portion and a spaced base portion, cleats spacing the floor portion from the base portion, retaining bars carried by the under face of said floor portion adjacent the ends thereof and spaced from the base portion, said retaining bars being spaced from the base portion for facilitating the removal of the lifting bars and the placing of the lifting bars in position, said retaining bars adapted to hold the lifting bars against accidental displacement.

2, A lifting device of the class described comprising a suspending bridle, lifting bars suspended by the lower ends of said bridle, a platform having a floor portion and spacers supporting the floor portion in spaced relation above a support upon which the platform is adapted to rest, retaining bars carried by the under face of said floor portion adjacent the ends thereof, said retaining bars having their lower faces arranged at an elevation above the lower edges of the means for supporting the floor portion to facilitate the removal of the lifting bars and the placing of the lifting bars in position, said retaining bars adapted to hold the lifting bars against accidental displacement, said platform, floor portion and spacers comprising an integral loadhandling pallet, and said retaining bars, suspending bridle and lifting bars in conjunction with the load-handling pallet providing a loadhandling device which may be placed on irregular surfaces as well as on flat surfaces.
