Specification of Letters Patent.

Application filed May 6, 1912. Serial No. 695.360.

"lo o il whom if may concern:

lle it known that we, Cuannns JnNuiNs and i MANDA A. JENKINS, citizens ot' the United States, residing at Philadelphia7 iu the county of I hiladelphia and State ot.' Pennsylvania, have invented certain new and uset'ul l'mprovements in Lite-Boats, et' which the following is a Specification.

Our invention relates to improvements in life boats. and has for an object to provide a plurality otl nested boats spaced apart for the acconnuodation of seats7 oars and the like.

A 't'urther object is to provide a plurality ot' lit'e boats which will not take up any more room on the deck ot a ship than one lite boat,yet will provide room tor many times the number of people.

A further object to provide a life boat preferably constructed ot sheet metal and having produce a light, yet durable and steady boat.

Vith these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more tul'ly hereinafter described and pointed out in the claims.

ln the accompanying drawings: Figure l. is a view in side elevation illustrating our improved nested boats in position on the deck ot' a ship. Fig. a top plan view of the boats. Fig. 3, isa view in cross seo tion ou the line 3-3 oit' Fig. 2. Fig. lt, is a view in cross section ot' one otE the boats removed. Fig. 5,' is a similar view illustratingr a modiitaitfion.

l, reprenents a Ship and Q the davits pivoted inthe bearings 3. (ln the deek ot the ship l are blocks 4, and these blocks support. our improved nested lite boats 5, one inside the other. We have illustrated in this instance t'our of these boats but we would have it understood that we do not limit odrselves in this respect as we might use more. or less.

Each of our improved lite boats 5 comprises a, shell preferably constructed of sheet. metal. shaped as shown. and the boats o't a Set are ot' Slightly ditlcrent sizes so that one will tity into another as clearly shown in Figs. and l. Around the edge utl the boat. brace bars (l are laeeured aud at intervals against the inner tace o't the sides and hottout. angle iron bars 7 are secured aut-l strengthen the shell.

stays to brace the same. which willA The keel 8 ot each boat is 'formed by bentliug downwardly the sheet metal ot the shell, whereby the upper portion 9 of the keel is hollow'and of general V-shape, so that the keel of the boat above will littherein and be guided therein in nesting the boats, as shown most clearly in Fig. 3.

Each boat i is supported ou its keel 8 and held by bars (3 and T ot the boat below so that a space is provided between the boats to accommodate seats l and .oars 1l. Ot' course, it is not necessary to remove the seats ot the upper boat7 and in this boat kegs of water l2 and boxes ot lood 13 are placed in sutlicient quantities to provide tor all the occupants of the boats.

ln Fig. we have illustrated a slight moditieatiou iu which the lite boat llis made of corrugated metal7 but otherwise the construction is the sante and we have applied the same reference clmraeters throughout.

For purposes ot' strength. the keel 8 is preferably made with au internal Strengthening bar 1S. v The boats are lowered vfrom thtl davits i? by the ordinary ropes l5 having hooked ends lti to engage iu rings 1T on the ends ot' the boats.`the top boat being lowered irst with its quota, ot water. lood, and passengers. and while one boat is heilig lowered. the seats., oars. water and tood are being arranged in the next boat' so that no time is lost. lu this manner any number of lit'e boats may be lowered requiring no more men to operate them than to lower one boat. liurtheriuore they require no more room ou the deck ot' a boat than one lil'e boat', lvetwill aecuuuuodate a proportionately greater number ot people. lt will be further noted that with our arrangement ol' nested boats, scarcely anyT more resistance is otl'ered to the wind than with one li'l'e boat. and therefore the speed ot' tht` ship will not be diminished be cause ot a larger number otl lite boats on board.

`While we have described a metal boat, we do not limit. ourselves to such material nor to the precise details set Forth. but cormider ourselves at liberty to make such changes aud alterations as fairly ,tall within the `spirit and scope ot' the appended claims.

ll'aving thus described our invention.what we claim as new aud desir'- to secure by letters latent is: A

l. 'lhc eomhiimtiou oty a ptnraiity' ui' nested boats. each boat (,-omprising a snell formed from e single sheet of metal, a keel i integral with the boat, a portion of said ke'el t Vshatped to receive the keel of another'bo'et,

ed boatif each boat comprising a shell formedii'from a single sheet of metal, a keel integral'with the boat, a portion of said keel V-shaped to receive the keel of another boat,

Y the remaining portion ofthe keel formed of two thicknesses ofmetal bent back upon each other, longitudinal brace bars at the inner edge of each boat, and angle iron bars secured to the inner 'face of the Sides and bottom ofeach boat7 each boat fit-ting into the next larger boat below, and supported on the bars therein., for the accommodation of seats and oars, substantially as described.

In testimony whereof we have Signed our names to this specification in the presence of two subscribing wltnesses.
