To all whom it may concern, 1 board Be it known that I, 501m H; SrosL'r; ai citizen of the United States, residing at Sebt'er-described and claimed.

I detail sectional of Michigan, have invented new and useful as to vessel to the davits for lowering by the lat-- "launched as soon as the cradle reaches the wide davits l which are 2 one deck 3, at onesideotfthe vessel, "and as within the vessel or extended out-board, in

ewaing, in the county of Huron and'State Improvements, in, Boat Lowering and Launch1ng. Means, of which the following is a specification. r

This invention relates ,to improvements in boat lowering and launching means for ves sels and consists in the 7 construction, combination and arrangement of deviceshereinaf- The object of my invention-is to provide improved boat lowering devices for vessels which devices are normally entirely away from ahd clear of the sides of the vessel so prevent any obstructions which interfere with the docking of the vessel;"a further object being to pro-videimproved means iorautomatically launching the boat as soon as the sanie is lowered; a further" object, be ing to provide improvedmeans for running a number of. boats from either side of the ter; a further object being to provide anim proved cradle in which th e'boat is normally kept, in which it is raised or lowered, and from which the boat is automatically required lowered position. In the accompanying drawings; Figure 1 is an elevation of a portion of a vessel provided with improved boat carrying, lower ing-and launching means constructed in accordanoe with myidnvention. Fig is a plan view. of the same. Fig. 3 isa detail side elevation of the same. Fig. 4 is a detail perspective view-of one of the boat carrying and launching cradles. Fig;s.,5, 6 and'.7 are views of parts ofsuch: cradles; I Y I In accordancewith my invention'I prohere shown as hav ing their lower ends pivotally mounted as at extendingthrough and being adapted to operate inslots of an upper deck 5, the said eslots being transverse with'reference to. the ,vessel. so thatthe davits are vangularlyrnovable transversely of the vessel andmay be disposed 'with'their upper ends entirely whichlatter position the .davits areshownin Fig. 3, the davitsgbeing also 'slmutn n out:

The ends oifit ecr is in place in the cradle extend over the boat and-securethe same firmly in place in the cradle, but the said links-enable the boat to a be readily'unfastened, it being only necessary to-unshi the locking rings 24 from the hooks 22, as ereinbeforestated, in order to thus release the boat, and this may be done almost in-an instant. v

p In connection with the davits andvthe boatcarrying cradles 7, which are slung therefrom, I provide guide rods 30, which extend transversely a slight distance above the upper deck -5 andextend vertically on the sides of the vessel to within 'a suitable distance of the water hue, and one of said guide rods extends downwardly farther than the other and has its lower portion bent in, arcuate form and disposed concentrically with reference to the lower end ofthe other guide rod, as at31. Said guide rods are disposed at a slight distance from the sides of the 'vessel and their lower ends are bent 'in'- wardlyand 'attachedthereto, as at 32. The

bars 11 of the cradle 7 are provided attheir inner ends with pivotally connected link rings 33, which en ageand are slidable on the guide rods 30. ormally when the davits are in-board and the cradles slung therefrom are also in-board the bars 11 of the cradles rise above the horizontal portionsofthe guide rods 30. When the davits are moved up-board', so as to dispose the cradles in such position, the link rings travel on the guide rods and they alsofdo so as the cradles are lowered by the tackle from the da-vits.

Assuming that the securing links 19, 20 have been released from the boats, as hereinbeforedescribed, when the cradlesfhave been disosed out'board and are -'1oweredfrom the avits by the tackle the cradles with the boats in them remain in a horizontal position imtil the-lower end of the shorter guide rodr30, has been reached and therefore only one end of the cradle descends'on the curved portion 31' of the other guide rod, so that the cradle isautomatically disposed in an inclined cradle-1s automatically launched therefrom" intothe water immediately alongside the osition and hence the boat.in the vessel. v

On the. upper deck ofthe vessel, in addi tion to the lowering and launching cradles herembeforedescribed, aregu-idmg and bedding cradles 39, which are fixed and lmmov 'ableon thefsaidupper deck, extend from'opposite sides thereof, converge rearwardly 'and have-their front ends disposed in line with the cradle 7 wh'n the latter are inboard, and their rear ends somewhat close together so that a pivotally mounted cradle.

At the stern of the vessel I show a pair of I tackle46. This cradle 45. is disposed para lel with the axis of the vessel so'that boats from the other cradlesmaybe readily-run thereon for .launc'hlng over the stern.
