To all whom it may concern:

- Be it known that I, Sornus Nrnon, a citizen of the Danish Monarchy, and a resident of Brooklyn, Kings county,

certain new and useful Im- This invention re ates to improvements in collapsible lifeboats, and the object of the invention is to provide a life boat of novel, practical and improved construction adapted 'to be easily and quickly unfolded in an emergency. a One object of the inventionis to provide a boat adapted to be folded into a compact 7 form so as to'occupy' but little space.

- Another object 'is to provide a construction whereby a continuous air. chamber is formed along the keel of the boat when it is unfolded. 7 i g I Other objects will appear as'thisspecification proceeds.

In the drawings illustrating the invention Figure 1 is aplan view of a collapsible life boat embody g the invention. Fig. 2 is a view online 2-2 of Fig. 1. Fig. 3 IS a view on line3'-3 of Fig.1. Fig. 4 is a view similar to Fig; 3 but showing the boat collapsed.

lafpsed. Fig; 6 is a detailview on line 6-6 v 0 Fig. 3, and Fig. 7 is a detail view on line 7-7 of Fig. 3.

I construct my lifeboat of any suitable material. Either wood or canvas made wa- 85 terproof, or of metal made rustproof, or I ma use a combination of these or other materials.

The sides are hinged some earner alongrthe keel line b a plurality-of-hinges 11 suitably secure to the and 7 and seen'in section in Fig. 2. This packing is preferabl{)m the form of a conrub er or similar packing material which is laid between the hinges and the sides 10 as shown. A portion. of

thepacki'ng 13 is turned 'up over the ends a of the sides and QaIIiQd dOWD-IDSIdQ-thQ boat New York,-

Fig. 5 is a plan view showing the boat'col- The boat consists of two symmetri-- below the fore and aft decks as a matter 'of' precaution. a i 14 is the gunwaleoi'railing for strengthening'and stifi'ening the sides.

The boat is provided'with' one or more seats each of which consists of two parts 15,

15 hin ed together in the center by hin es It} an hinged to the sides of the,boat y hinges 17. A false bottomis provided a distance above the keel and comprises the two parts 18, '18 hinged together in thecenter by hinges 19 an hinged to the sides 10 by hinges20.

A short deck is provided at each end of the boat. Each deck comprises the two symmetrical parts or

halves

21, 21 hinged together in the center by hinges 22 and ngpd to the sides of the boat by hinges 23.

hi As est seen in Fig. 6 the deck portions 21, 5

.21 are each provided with a depending flan e, 24. v

ertical walls or partitions are provided to separate the space under the decks. from the interior of the boat. Each wall comprises two

parts

26, 26 hinged like doors to the sides of the boat by hinges 27 and hinged together in the center by hinges 28. The

hinges

27 and 28 arespring hinges having springs 29 inserted in known manner. The tendency of the springs is to keep the partitions vertical and closed as shown in Fig. 7 which illustrates one of the walls in plan view and section.

For the purposes of air-ti h tness and water-tightness all edges] and a utting surfaces of the various members described are provided with packing stri s -30-such as seen in Figs. 6 and 7. Prefera ly the strips are set in suitable grooves. Suitable packing will alsobe emp oyed around the hinges. x V

The boat 15 'rovided' with oarlocks 31- and eyes 32. T e latter for the use of the .ropes with whi h the boat is lowered, and

when the boat is collapsed, chains or other 1 means may be passed through the eyes to prevent the boat from unfolding.-

p 33 is a ring secured to once the bottom parts 18.

From the foregoing it will be a parent that when unfoldedthere is provide an air chamber 35 in the bottom of the boat and large air chambers 36 at either end under the decks and that these air chambers are'all in-communication. They assist in keeping 11 the boat afloat. l f

Where the boat is unfolded as in Figs. 1

to 3, the decks, partitions, seats and the bottom aforesaid are folded out straight and as they are nicely fitted in the boat they exert a pressure on the sides thereof,'preventing accidental collapse. The springs 29 assist in keeping the

partitions

26, 26 in line and also press them a ainst the packings 30 in the depending flanges 24 of the decks and the packings 30 in the ends of the bottom as shown in Fig. 6. The walls break in the direction of the. arrows in Fig. 7 that is, thcy fold outward toward the ends of the boat. To prevent any accidental break of the walls 26 I may rovide each one with a latch 40 as shown in ig. 3. 7

Normally the boat is collapsed as seen in Figs. 4 and 5 from which it will be clear that the bottom, the seats and the decks fold upwardly and the walls 26'fold endwardly of the boat as already explained. This folding of the aforesaid. parts permits the sides of the boats to be closely folded together along the keel line so that the folded boat occupies but very little space.

When unfolding the boat, the sides are pulled apart and the seats, decks and botforming a keel, a

tom pressed down and straightened out. The walls 26 straighten automatically by the springs 29. The natural pressure of the occupants tends to keep the parts straightened and the boat unfolded. The ring 33 is for the purpose of folding up the bottom.

It will be seen that the boat comprises practically'two symmetrical halves adapted to fold along the centerline of the boat so as to occupy but little s ace and which are also adapted to bequic y unfolded for use. Further, that the decks, walls 26 and the bottom provide a protection against injury to the sides and at the same time keep the sides apart and form the air chamber referred to. -Various changes in the detailed construction may be made without departing from the spirit of the invention and within the scope of the appended claims.
