HOISTING AND LO'i/VERING COLLAPSIBLE LIFEBOATS.

Application filed May 28,

T 0 all w 710m it may concern Be it known that I, GlOYANNI Rmnsr, a subject of the King of Italy, and residing at Genoa. Italy. have invented certain new and useful Improvements in Hoisting and Lowering Collapsible liifeboats, of which the following is a specification.

The invention comprehends generally improvements in that class of inventions known as ships and more particularly has reference to improvements in means for extending collapsible life-boats and for releasing the life boats.

It is the primary aim and object of the present invention to provide an apparatus of the above mentioned character wherein improved coacting means are arranged on the solid lower portion and the gunwale of the life-boat for association with the lifeboat raising and lowering tackles whereby when the ship davits are swung outwardly the means will be automatically extended and by reason of the association of this means with the life-boat the collapsible portion of the life-boat will be aiiitomatically extended.

The invention as an equally important object contemplates the provision of manually operable means for releasing the means which effects an extension of the life-boat from the tackles, subsequent to the lowering of the life-boat into the water.

Among the other aims and objects of this invention may be recited the provision of an apparatus of the above mentioned character with a view to compactness and wherein thenumber of parts are comparatively few, the construction simple, the cost of production low and the GillC-lQIlCY high.

Further objects as well as the nature, characteristic features and scope of the invention will be more readily apparent from the following description taken in connection with the accompanying drawing and pointed out in the claims forming a part of this specification.

The invention is clearly illustrated in the accompanying drawings, in which Fig. 1 is a transverse sectional view through alife-boat showing the means for. extending the lifeboat partly in elevation and partly in section,

lines indicating the positions assumed by the parts when collapsed,

Fig. l is a fragmentary side elevational view of the arrangement shown in Fig. 2 collapsed,

Fig. 5 is a longitudinal sectional view. throughout the entire length of the life-boat showing the same extended and the means for extending" the collapsible sides in side elevation,

Fig. 6 is a top plan view of the arrangement shown in Fig. 5, and i Fig. 7 is a plan detail of the means for releasing the means which extends the collapsible sides of the boat.

Similar characters of reference are employed in all of the above described views to indicate corresponding parts.

Referringnow, more particularly. to the accompanying drawings there is provided a life-boat of the collapsible type including generally a stationary or solid lower portion 1. a gunwale 2 supported through the instrumentality of foldable struts 3 which are-formed in sections pivotally-connected to each other and pivotally connected at their free ends to the portion 1 and gunwale 2 respectively. Collapsible side portions of flexible material are connected between the gunwalc 2 and the portion 1 while suitable seats 5 are mounted within the boat. In this connection it may be mentioned that the details of construction of the life boat per se as well. as means for holding the same extended form a part of my copending application bearing Ser. No. 473,301, filed May 28. 192]. \Vith a view toward providing improved means for effecting. extension of the boat. the latter is fitted fore and aft with spaced parallel tracks 6-which are connected at their outer ends to the gunwal'e and at their inner ends to the cross bars 7. Situated beneath each pair of tracks and pivotally mounted as at 8 to the upper surface of the stationary portion 1 of the boat are the lower or inner ends of elongated supporting wings 9 the upper ends of which are pivotally associated with the inner ends of a pair of offset upper links 10 through the instrumentality of an elongated shaft 11 the projecting portions of which serve as a means for rotatably supporting rollers 12, the latter being arranged beneath and adapted to coact with the track bars 6 by contact so that when the supporting link structures are raised the rollers by operating on the tracks will effect a raising of the tracks and an ultimate extension of the collapsible boat 1 as apparent.

Pivotally supported between the spaced upper ends of each of the upper pair of links by a pintle 13 'is'a hook 14, the shank of which carries a weight 15 for a purpose which will presently appear. As

apparent each hook 14 is designed to ngage the adjacent ship tackle (not shown) so that upon outwardly swinging oi? the davitsyof the ship (not shown) the weight of the stationary lower portion acting against the point of suspension of the hooks will automatically move the link supporting structure into a vertical position while as inti-' mated the roller acting on the track 6 will effect automatic extension of the boat simultaneouslytherewith. Each pair of upper links 10 are formed with xtensions 16 which form combined guards "for the hooks and'supports for rollers 17 for a purpose that will presently appear.

As intimated improved means has been provided for releasing the hooks from the boat tackles (not shown) subsequent to the lowering of the life-boats in the water and in reducing this feature of the invention to j practice flexible elements such as chains 18 have their outer ends connected to the weights 15 and are trained about the rollers 17 fon the upper links and thence about rollers 19, 20 and 21 on the upper surface of the stationary lower structure .1 and have their inner ends rigidly connected at opposite points on the periphery of the drum 22 inountedin a suitable housing- 23 secured to the structure 1 in proximity to the rollers 21 th arrangement being shown in Figs. 6

and T. A lever 24 is rigidly connected with one trunnion 25 of the drum and it is apparent that upon rocking this lever in either direction corresponding pulls will be exerted on the chains and by reason of the n anner,inwhich the chains are guided up ward pulls will be exerted on the hooks so as to effect a release thereof as believed apparent. I y

' It is believed in view of the foregoing "that a further detailed description of the operation of the invention is entirelyunnecessary. Likewise it is believed that the advantages will be readily apparent.

Having thus fully described the invention what is claimed as new and desired to be secured by Letters Patent is zv 1. The combination of a collapsible liteboat including asolid lower structure, a gunwale, flexible extensible side portions between the lower structure and the gunwale.

of spaced parallel tracks mounted fore and aft of the boat, foldable link supporting structures mounted on the lower solid struc--- ture, weighted hooks pivotally supported in v the outer ends of the link structures and adapted for engagement with tackles of a ship rollers mounted on the link structures for association with the track where 3y when the life-boat is movedoutwardly for lowering into the water the weight of the lower structure will effect extension of thefoldable link structure while the engagement of the rollers with the track will effect an extension of the collapsible sides of the boat simultaneously therewith.

2. An apparatus as claimed in claim 1 wherein manually operable means is 1nount-' tensions serving as'guards for the hooks and as a roller supporting means. r
