' M. ABRIANI SHIP uNLbADr-Ne DEVICE Filed July 30, 1927 INVENTOR 7V MAR/0 A5214 BY W 1% ATTORNE Y Patented June 17, 1930 PATENiTi. OFFICE mm ABRIANI, or GENOA, ITALY.

SHIP-UNLOADING DEVICE Application filed July so, 1927, s wn No. 209,485, and in Italy August 16, 1926.

The present invention refers to a ship unloading device of the greatest structural simplicity with the advantage of conveying merchandise very quickly, much quicker than is usually done directly from the hold to the deck and by means of a chute directly from the deck to the quay or the lighters without using pulleys, cables and the like; moref over the'device according to the-invention may be arranged as wellwithin the air-hoses or ventilating-tubes or in the masts or supporting columns of booms without encumbering either hold or deck but occupying spaces hitherto not utilized. I

Only by way of exampleflthe device is schematically illustrated in the accompanying, drawings in which:

Fig. 1 shows a vertical section on the lin 1-1 of Figure 2;

Fig. 2 shows a front View;

Fig. 3 is a section on line 22 of Fig. 1.

The device comprises a standard theuprights of which are formed of coupled channel irons, so that between them the car steeringand tractionpivots may glide, the ends of the uprights being shaped so as to guide the movement of the car pivots and cause the cars to take the horizontal position for loading, the inclined position for unloading, and the vertical one for their descent into the hold.

As illustrated in Fig. 1 the uprights aand bhave their middle part vertical and parallel while their lower and upper ends show curves of a predetermined radius to oblige the end pivots c 'd to causethe cars to take in their rotation the diiferent necessary positions for working.

The uprights -,e. "are rectilinear and parallel and act as guides for the central traction pivots -gconnected to endless chains h passing around wheels i and -.Z-. The upper wheels -iare coaxial with driving wheels -mwhich may be acted upon 'by any motor and relative speed reducers. The lower wheels l are provided at the end of their axle with drums The cars -0 have fixed thereto pivots -cgd-, Z acting as guides and are slidable bebent and conveniently the pivots cand.

tween uprights 'a,- and b. The pivots g are connected to the endless chains and move on the uprights .-eand f, these uprights beingplaced at a distance from one another coinciding with the diameter of wheels -'Z and Z.

The terminal parts of all the uprights are dlv'erglng so that the various )pivots may. readily enter and move from the same.

The device is capable of being extended or 'shortenedaccording to the exigencies of the case by increasing or taking oil a part of the uprights. I

In theoperation of the invention the carriages successively assume a substantially horizontal position at the lower ends of the uprights a and 6. While in this position the objects to be removed from the ships hold are placed thereon and carried upwardly.

As the carriages reach the'upper ends of the uprights they are caused to assume a substantially vertical position to dump the objects therefrom. When it is desired to load a ship the mechanism will be driven in a direction reverse to the arrow disclosed at the upper end of Figure 1 to carry the objects downwardly. I

Having now particularly described and ascertained the nature of said invention and in what manner, the same is to be performed I declare that what I claim is:

1. In connection with an air pipe in ships, a plurality of conveying plates moving up and down within said pipe, said plates being provided with end lugs and central lugs at two opposite. sides, funicular members pivotally connected to said central lugs, upper" and lower wheels to guide and drive said funicular members, rectilineal guides tangent to said upper and lower wheels wherein slide said central lugs, upright guides for the said end lugs, extending between the center levels of said wheels, outward vcircular and discontinued guide sections forming a continuation of one set of said upright guides and cooperating with the other set to swing the conveying plates to an inclined unloading position, rectilineal descending guides parallel to said upright guides cooperating with one set of said tangent guides to keep the conveying plates in an inclined position while descending within said air plpes, curved guide sections joining one set of said upright guides from the center line of said upper wheels to the said rectilineal descending guides and co operating with the said circular guide sections to swing the conveying plates to their inclined descending position, curved guide sections at the lower ends of the said rectllineal descending guides, curved guide sections at the lower ends of the said upright guides to receive the end lugs as left free by the said circular guide sections and said rectilineal descending guides, when the conveying plates have reached the hold and have taken their horizontal position.

2. In connection with air pipes in ships,

an unloading elevator mounted in said pipe and comprising a'plurality of elevating'members, said elevating members being provided with end lugs and centrally disposed lugs on opposite side edges thereof, continuous funicular membersto drive said elevating members up and down within said pipe, means disposed vertically Within said pipe and coacting with the end lugs whereby said elevating members will be guided in a horizontal position while ascending, means carried Within said pipe substantially adja cent said first-named means parallel thereto and coacting with the centrally disposed lugs whereby said elevating members Will be guided in an -inclined position while descendmg, and means carried at the-lower end of said second-named means adapted to swing said elevating members into horizontal position before reascending.

3. In connection with air pipes in ships, an unloading elevator mounted in said pipe and comprising a plurality of conveying plates, continuous funicular members adapted to drive said conveyor plates up and down within said pipe, vertically disposed guide members carried within said pipe, said guide [members being provided at their opposite ends with arcuately-shaped portions, pairs of vertical guides carried Within said pipe and adapted to coact with said first-named guide members, said second-mentioned vertical guides being disposed substantially With in the arcuately-shaped portions of said firstnamed guide members, and means carried at the lower ends of said guide members for horizontally disposing said conveyor plate at the termination of their descent.

In testimony whereof I have hereunto signed my name. v

MARIO ABRIANI.
