UNITED STATES PATENT OFFICE.

MANNEVILLETTE E. D. BROWN, OF UTIGA, NEV YORK.

LIFE-BOAT.

Specification of Letters Patent No. 23,442, dated April 5, 1859.

To all whom it may concern.' l

Be it known that I, MANNEVILLETTE E. D. BRowN, of Utica, county of Oneida, State of New York, have invented certain Improvements in the Construction of Life-Boats to be Used at Sea.

My invention consists mainly in the union or combination of three boats in one, and I do hereby declarethat the following is a full, clear, and exact description of the plan of constructing and using the same, reference being had to the annexed drawings and the letters of reference marked thereon, making a part of this specification, in which Figure lst represents one end of the boat (t-he bow and stern being alike). Fig. 2d longitudinal elevation and outside view of boat. Fig. 3d obverse inside view of length and width of boat. Fig. 4th reverse inside view of length and Width of boat. Fig. 5th transverse section, midway the boat. Fig. 6th view of rudder bolt and perspective view of rudder iron.

To enable others to make and employ my invention I proceed to state that I use metal, wood, or any other suitable substance to construct my boat and all appurtenances thereof.

To construct my boat I make two boats of similar material, form, and proportions, each of which I make with a flat bottom (Fig. 3d, z', z',), and the gunwales, or one side (Fig. 2d, a, a,), which I name the outerside, corrugated or straight and at right angles (Fig. 5th, a, a,) with the bottom of the boat; and the other side, which I name the innerside (Fig. 5th, 7c, c,) of an irregular shape or a straight beveled angle with the bottom of the boat. I place these two boats innerside by innerside (Fig. 3d, la, if; Fig. 4th, 7J, 7c; and Fig. 5th, 7c, 70;) parallel longitudinally, and in a precisely similar position relatively to each other, and as far apart as may be desired. The distance of these boats apart once chosen I iX them in position (Fig. 5th) by partitions made of the same material and of the same form as the bottoms of the boats (Fig. 5th, a', L) and unite one side longitudinally or edgewise by bolts or other known ways firmly to the upper part and outward side of the innerside of one boat; and the other side or edge I unite in a similar manner and in a similar place to the innerside of the opposite boat. The space or recess between the inner-sides of the two boats (Fig. 3d, Z,) serves as a hold and, together with the bottoms of the two boats (Fig. 3d, Yz', 27,) as benches, answers the purpose of another boat, which I name the obverse side of the boat in contradistinction to the other side, which I call the reverse side of the boat. The ends of the boats (Fig. 4th, 7L, m, m; z, m', my) I unite in any shape desired so as to form but one end forward and one end aft, and thus united form three boats in one or a three recessed boat.

To ship the rudder I make a groove or grooves in the rudder iron (Fig. 6th, g,) and have a peg (Fig. 6th, s) of suitable size inserted in the rudder bolt (Fig. 6th, 5,) so that the rudder when shipped may not easily be unshipped by the action of the waves.

)Vhat I claim as my invention and desire to secure by Letters Patent is l. The construction of a life boat with three recesses, substantially in the manner and form and for the purposes as above specifically set forth.

2. Also in combination with the foregoing the making a groove in the rudder iron and a peg in the rudder bolt as above described for the purpose as above substantially set forth.
