OF LONDON,

ENGLAND.

Specification of Letters Patent.

Patented Mar. 30, 1915.

Application filed June 7, 1913. Serial No. 772,322.

To all/whom it may concern:

Be it known that we, ISAAC FRANCIS TAY- LOR and SAMUEL PICK, subjects of the King of Great Britain and Ireland, residing at 5 Upland road, East Dulwich, London, S. E., England, and 117 Queen Victoria street, London, E. (1, England, respectively, have invented certain new and useful Improvements in Ships-Boat Storing, Lowering, and Raising Apparatus, of which the following is a specification.

This invention has for its object to enable boats to be stored and to be launched quickly and safely from store from either side of a ship and to enable a number of boats to be loaded with passengers before being carried outboard and lowered.

According to this invention carriers such as chains or wire ropes are mounted to run on tracks or supports arranged athwart the boat deck, and above the carriers is a platform supporting the raising and lowering gear which comprises pivoted cantalivers or davits adapted to swing out to throw the boats clear of the ships sides and carrying pulleys over which the falls pass to a Winch barrel provided with a brake arranged to act.

on the drum of the winch to control the lowering of the boats.

Between the carriers which are spaced apart a suitable distance the boats are arranged to be suspended by attachment at the stern and stem, and when outboard are disengaged from the carriers and engaged with the falls. Whenstored the boats are supported on the boat deck below the carriers on chocks which are lowered when the boats are ready to be run outboard so as to be out of the way of the keels of the boats.

In the accompanying drawings, Figures 1 and 2 are elevations at right angles of boat storing, lowering and raising apparatus constructed according to this invention. Fig.

.3 is a sectional plan showing the chocks,

Figs. 4 and 5 are end and side elevations of the boats. Fig. 6 is an elevation partly in section of a modified construction of an apparatus, and Fig. 7 is an elevation at right angles to Fig. 6.

As shown in Figs. 1 to 5 a framing is erected on the boat deck a consisting of stanchions b supporting bearers or beams b b at their upper ends for the platform and chain tracks 0 fixed to the stanchions at a suitable height on which endless chains 03 are supported. Each chain track is formed of a pair of plates 0 0 having flanges 0 at their lower ends upon which rollers 03 upon the endless chains (Z are arranged to run, eyes d attached to the chains being arranged to hang between the flanges. The chains'run between the track plates 0 0 and over sprocket wheels 6 mounted at opposite ends of the track, one or both pairs of sprockets being connected by shafts such as 7 adapted to be operated through worm gearing g, spindle hand hand wheel a from the platform or by a crank handle applied to the end of the shaft at f. Near the ends of the boats suspending hooks j are pivotally mounted which are adapted to be engaged with the eyes (Z? on the chains. These suspending hooks y' are pivoted-at the stem and stern between cheek plates 7" provided with a pair of upwardly projecting fingers or prongs y' arranged to disengage the eye of the falls when the hook drops by its own weight on the load being taken off when the boat is waterborne. Two or three hooks may be carried on the same shank, one indicated by the reference 1, serving to connect with the carrier chains, another 2, with the falls for lowering the boat and another 3 in cases where the falls are attached to raise the boat on board. In the latter case the hook 3 has a spring closing tongue 3 to prevent accidental release of the rope.

Several boats can be stored below the chains d which extend from side to side of the ship, or as far as space will permit, and other boats are brought into position by means of 'a trolley 70 or the like moving on a track k which extends along the boat deck to the carrier. This trolley is prevented from leaving the rails by brackets k which project from the frame of the trolley under the rails as shown in Fig. 1. The falls Z on the same side of the ship run over pulleys m on the outer ends of pivoted cantalivers or davits n and over other pulleys m to the 1 same, winch barrel m mounted on the platto control the lowering of the boat. Suit able means are provided to disengage the falls when the boat is water-borne, after which the falls are raised by rotating the winch drums. Suitable motive power may be employed to operate the winch when it is desired to raise a boat.

Each cantaliver or davitncomprises pairs of spaced or bifurcated arms a n c0nnect ed together by brace bars a and pivoted at n to'a suitable base 72 fixed to the beams 12. A link or stay 27 also pivoted to the base a passes over the inner arms a and limits the outward movement of the cantaliver. In their, outboard positions the cantalivers are locked by catches Q which engage under the beams b of the framing. When the falls are wound up by rotating the .winch drums the catches q are released by weights or balls g on the falls Z just before said balls engage the undersides of the cantalivers. By the further upward movement of the weights the cantalivers are caused to swing inboard about their pivots 91/. During this movement the balls seat themselves in hook shaped projections 10 on the outer armm, of

- the cantaliver, so that on a boat being sub .sequently connected to the falls the weight first-acts through the balls and hooks n to pull the davits outboard. In some. cases the outer arms of the davits diverge below the projections n to the pivots at, to leave a 'free space between them so that should it be desired to raise'goods or mail packages by the davitssuch goods can be swung through the davits and delivered into a chute in the deck. i

As clearly illustrated in Figs. 1 and 3 the chocks are-formed of transverse beams s suitably recessed at s to receive the heels of the boats and spaced apart to engage the boats near the bow and stern. Pivoted de pending links t connect the chock beams s with a series of angle levers u mounted to oscillate. in a vertical plane on suitable brackets '12 fixed to the deck, the levers u of each beam being connected with a common rod u extending along the underside of the beam, the rods u being themselves connected by bell crank levers u and rodding u with screw gear a actuated'by a spindle u and hand wheel w. Vertical guides 03 ex tend upward between guide rolls w on the chock beams to prevent longitudinal movement of the beams which are maintained carry two or morerows of boats one above the other or at the same level. Aoonstruc- 'tion is illustrated in Figs; 6 and? for carrying two rows of boats. Inthis construction the endless carrier chains d -run alongside grooved tracks 0 over which run rollers d o nte o ly on spind esdtw p v in the links of the chains. "Bars 1' extend between the two carrier chains (Z and are provided with eyes 03 for the suspension of the boats. These? bars are fixed to or formed integral with the spindles (Z of the rollers so that the bars can turn-freelyv about their longitudinal axes to enableYthe'boat .suspending eyes d flto' hang vertically when passing around the ends. of the guide tracks. For actuating the endless carrier chain in spur wheels 0 on theshaft: 7 which is actuated through worm gearing g h andhand wheel z'yor by a crank handle applied to the:

end of the shaft in thesame manner as the shaft f hereinbeforedescribed; Chocks .s are provided for the upper row of boats and operated in like manner tothe chocks already described, the hand wheel w and-screw gear actuating thelowerchocks being'also connected with the upper chocks by a connecting rod-and. suitable levers. 1

In an apparatus "for storing, lowering and raising ships boats, the combination of endless carriers disposed transversely of the ships;tracks for said carriers and extend? ing from side to sideof the ship; boat lowering and raising gear cooperating with the carriers; a series of chocks for supporting the boats in position under the carriers; 1'

said boat lowering and raising gear comprising davits adapted to swing outboard in vertical planes to throw the boats clear of the ships sides; falls on said davits; and 1 means for locking the davits in outboard position and adapted to be releasedby the winding up'of-the falls.
