SYSTEM FOR HANDLING LIFE-BOATS.

Application filed March 10, 1913. Serial No. 753,281.

To all whom it may concern Be it known that I, Nns'ronn MARTINoLicrr, a subject of the Emperor of Austria-Hungary, and resident of Triest, Austria-Hungary, have invented certain new and useful Improvements in Systems for Handling Life-Boats, of which the followmg 1s a specification.

My inventlon relates more particularly to an arrangement of the lifeboats crosswise of the boat deck in convenient groups of three or four, the boats of each group preferably being arranged to be swung out and lowered simultaneously by means of a suitable winch. Two or more groups may be arranged to be operated by the same winch, either simultaneously with another group or separately, as desired.

The object of my invention being to produce a condensed arrangement of a large number of boats on the boat deck and yet have them so arranged that one or all can, with the least possible delay, be lowered to the water by a small number of men; a very important consideration on ships carrying a large equipment of life boats and comparatively few available men.

In carrying out my invention, I have arranged the life boats along the edge of the ship crosswise of the boat deck, each boat resting on rollers adapted to facilitate rolling the boat longitudinally over the edge of the deck. At the edge of the boat deck adjacent to each boat there is located a davit post carrying a fixed fall-block support and a movable support or derrick adapted to be swung out so that its outer end is substantially in a plane passing through the end of the fixed support and the middle of the associate life boat, which, as previously stated, rests on the boat deck crosswise thereof. When the ship is at sea the derrick arms are preferably swung out as indicated and secured in that position and are to be swung in to lie parallel with the side of the ship only when in harbor or at other times when necessary. One form of my invention is illustrated in the accompanying drawings of which Figure 1 represents two groups of lifeboats on the boat deck, arranged according to my system. Fig. 2 is a side view of one of the davits and associated parts with a boat swung out ready for lowering.

Referring to the drawings A is the boat deck crosswise of which the lifeboats B are arranged in as many convenient groups as Specification of Letters Patent.

is also provided with a painter Patented Aug. 19,1913.

required, two groups of three each being here shown. The boats are supported or rest on rollers C, the ends of which are adapted to roll on ways D in the usual or any preferred manner so that in hauling the boats out the rollers move to the forward dotted positions indicated. At the edge of the boat-deck there is secured a davit post E for each life boat extending above the deck as high as required and to which is secured the laterally extending fixed bracket F which is secured to the davit at a suitableelevat-ion to permit the boat to readily pass under it when hauled out. The bracket F is secured to the davit post E in any suitable manner as indicated in Fig. 2. I also secure to the davit post another longer arm or derrick Gr preferably adapted to swing horizontally and which may be swung alongside the deck, if desired, but is preferably arranged to be secured in working position extending outward from the deck as indicated in Fig. l of the drawings. The derrick arms G may be secured in operative position in any preferred manner but I have shown all the arms G of the two groups in Fig. 1 as connected by a wire rope H the ends of which are secured to the edge of the boat deck A. This arrangement permits readily swinging all the derricks into or out of operative position simultaneously and facilitates securing them in place. The fixed davit arms and the derrick arms are suitably braced by tie-wires or rods as indicated and each is provided with a fall block K, L through which fallropes pass. The fall-rope M passes through the block K of the fixed davit arm and is releasably secured to the stern of the boat at N while the fall rope 0 passes through the outer fall block L carried by the derrick arm G and thence to the bow of the boat at P as clearly indicated in the drawings. The usual releasing hooks are used at N and P so that when the boats are on the water, they may be freed from the fall ropes. Each boat Q secured to the stern in the usual manner as indicated in the drawings.

The innerends of the fall ropes M and O are preferably wrapped around and secured to which drums It both falls being wrapped in the same direction while the ends of the painters Q are preferably wound about the drums at R in the opposite direction so that winding up the lines M and O pays out the painters Q and the boats B will be and the winch is started.

drawn over the rollers C and swung to the position indicated by the dotted lines in Fig. 1 or the full lines in "Fig. 2. In this position the ends of the painters may be thrown off or released from the drum R automatically or otherwise and by reversing the clirection of rotation of the drums R the fall ropes M and O are paid out and the boats lowered to the water.

The drums R for each series are preferably connected. together as by mounting on a common shaft S and one or more such groups may be operated from a common winch T which may be steam, electric, hydraulic or hand operated as preferred. In hauling in the boats the reverse operation takes place, that is, the boats are fastened to the outer ends of the respective fall ropes thus winding up the fall ropes M and O on the drums It until the bottoms of the boats are clear of the boat deck, then the respective painters are carried in and hooked or secured to the drums at R. The winch is then reversed and the painters are wound on the drums at R in the opposite direction as the fall ropes pay off the drums and the boats are hauled over the rollers C to their proper positions crosswise of the deck where they may be secured in place by suitable means such as the chain hooks V shown in Fig. 1 of the drawings.

Various modifications of the details of construction may be made without departing from the spirit and scope of my invention as claimed.

I claim:

1. In a system for handling lifeboats, the combination of means for disposing and supporting the boats crosswise of the boat deck, a davit post for each boat, a pair of laterally extending fallblock supporting arms secured to said davit posts, fall-blocks on said arms, fall ropes therefor and means for simultaneously operating said fall-ropes to move the boats longitudinally, crosswise of the deck and to lower the same to thewater substantially as described.

2. In a system for handling life boat-s, the combination of means for disposing and supporting life boats crosswise of the boat deck, a davit post for each boat extending above the deck, fall-block supporting arms extending therefrom, the outer ends of said arms being located in a plane substantially at right angles to the edge of the boat deck, fallblocks carried by said arms, fall ropes passing through said fall-blocks and releasably connected to the respective life boats and means for simultaneously operating said fallropcs to move the lifeboats crosswise of the deck and to lower the same to the water substantially as described.

In a system for handling lifeboats, the combination of means for disposing and supporting lifeboats, crosswise of the boat deck, a davit post for each boat a fixed fallblock support and a movable fallblock support extending laterally from said post, means for securing the movable supports so that their outer ends are spaced from the outer ends of the respective fixed supports, said ends lying in a plane substantially at right angles to the edge of said boat deck and passing through the middle of the corresponding lifeboat placed crosswise of said deck, fall-blocks on said davit supports, fallropes passing through said blocks and releasably connected to the associated lifeboat, one at the bow and one at the stern, whereby by hauling on the opposite ends of said fall-ropes the lifeboats are moved longitudinally and swung over the side of the ship, substantially as described.

4:. In a system for handling lifeboats, the combination of means for disposing and supporting lifeboats crosswise of the boat deck, a davit post for each boat a fixed fallblock support and a movable fall-block support extending laterally from said post, means for securing the movable supports so that their outer ends are spaced from the outer ends of the respective fixed supports, said ends lying in a plane substantially at right angles to the edge of said boat deck and passing through the middle of the cor responding life boat placed crosswise of said deck, fall-blocks on said davit supports, fall-ropes passing through said blocks and releasably connected to the associated lifeboat, one at the bow and one at the stern, whereby by hauling on the opposite ends of said fall-ropes the lifeboats are moved lon- V gitudinally and swung over the side of the ship and means for simultaneously hauling the boats back into normal positioncrosswise of the boat deck, substantially as described.

5. In a system for handling life boats, the combination of means for disposing and supporting a boat crosswise of the boat deck, a davit post for said heat, a pair of laterally extending arms ;secured to said davit post, fall blocks on said arms, fall ropes therefor, and means for operating said fall ropes to move said heat longitudinally crosswise of the deck and to lower the same to the water substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
