MAXIMILIAN SCHMITT, OF PATERSON, NEW JERSEY.

BAT STRUCTURE.

Specification of Letters Patent.

Patented Jan. 18, 1916.

Application filed May 28, 1915. Serial No. 30,882,

To all/whom t may concern:

Be it known that l, MAXIMILiA'N SCHMITT, a subject of the Emperor of Germany, re

siding at Paterson, in the county of Passaic and State of N ew Jersey, have invented certain new and useful improvement-s 1n Boat .Structures of which the following is a specification.

The object of this invention is to provide a canoe or similar boat-like structure of the class built end for end substantially alike that shall be capable of being produced by a method considerably simpler than those heretofore employed and possess in full measure the usually desired qualities of grace, symmetry, durability and lightness, together with increased flexibility, so that it will be especially adapted to withstand shocks and blows incident to the handling thereof'and particularly to contact With obstacles, such as rocks and the like, When afloat.

ln the accompanying drawings, Figure-1 is an underneathplan view of the frame and a mold, assembled, showing a canoe in process of manufacture; Fig. la is a sectional detail of the frame; Fig. 2 is a side elevation of what appears in Fig. l;`.Fig. 3 is a transverse sectional perspective view of a fragment of the canoe; Fig 'al shows one of the shell sections in inside perspective; and, Fig. 5 is a sectional view on line of Fig.

l provide a skeleton frame which preferably consists of a longitudinal central member, a traverse central member and gunwale members. To form the longitudinalI` member, l employ a liet strip a and the upt-urned or stem pieces a suitably affixed to the ends of the strip a; the parts and a may be formed, desired, all in one piece, but they are preferably separate pieces suitably joined, as shown.

To form the transverse member l bend a flat strip l) 'so as to leave its end portions li standing upright, as shown. To form the gunwales, l provide'the two strips c c suit-ably shaped to the contour, in plan, of the canoe. flhe members c and F) may, if desired, be connected by a check-joint where they cross (Fig. la). The members c c are suitably secured to the stems a a and to the upturned ends of the member bearing against the inner sides of the latter. Having formed this frame, I preferably lit into the same a mold or matrix Z which conforms to the shape of the canoe to be produced, vand which is made sectional so that it may be removed after the canoe is completed; how the sections of the mold are related and removably secured in the frame is not material, though in accordance with the. purpose in utilizing the mold itmay be remarked that it is formed with suitable grooves at e for the reception of the members a, b and c of the frame, so that they shall be inset therein and havea their outer surfaces iush with the workingr surface of the mold. Pieces of veneer, each preferably made upl of layers of-Wood f glued together face to face, the grain of adjoining layers crossing, are then formed and cut and pressed into pairs of concavo-convex shell sections, the members in each pair of which as to size and shape are substantially exact counterparts of each other and at the inside substantially exactly fit diagonally opposed portions of the mold. These sections g are then secured one after another to the frame in edge-joined relation to each other so that a complete composite shell remains built up on the frame when all have been secured in place; they may be secured to the frame merlbibers by screws or the like, as indicated at While the mold is not indispensable in the operation of securing the shell sections g to the frame, still it very materially assists as a support for said sections while they are being fitted into place and secured to the frame.

In the preferred Vconstruction the edgejoining of the sections is accomplished by beveled lap-joints z' (see Figs. 3 and 4)..

Vhen the shell sections have all been secured in place and, if necessary, the joints and edgesthereof finished off smooth and to Y a'shapely form, a coating of duck or the like flexible material j is applied to the outsidev I of the shell and thenvpainted or otherwise made waterproof.

Much time and labor are saved by manufacturing canoes and boat like structures of the kind indicated in accordance with the improved method herein set forth; besides, the finished product is strong, light and durable and may be made to possess all the grace and symmetry usually required in such structures.V My invention makes it possible. further. to reduce the frame structure to the simplest form, as will be obvious on reference to Fig. 1, and l obtain in conblows due to Contact with submerged rocks or the like without dalnage'to the shellor other injury l Having thusfully described my' invention, what I' claim as new and desire -to sentire by Letters Patent is The hereindescribed boat-like structure of the class having its fore and aft halves substantial counterparts of each other including a frame and a composite shell attached to the frame, sald shell Including two pairs of stiff' sheet concave-convex sections and the sections of each pair being diagonally opposite to L,each othervand being also sub stantial counterparts of each otherin size and shape.

In testimony whereof I affix my Signature.

MAXIMILIAN SCHMITT.
