BOAT.

SPECIFICATION forming part of Letters Patent No. 757,832, dated April 19, 1904.

Application filed May 21, 1902. Serial No. 108,400. (No model.)

To all whom it may concern:

Be it known that 1, JOHN CHRISTOPHER NIoIIoL, of the city of Montreal, district of Montreal, Province of Quebec, Dominion of Canada, have invented certain new and useful Improvements in Boats; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates particularly to molded boats of the type disclosed in Letters Patent of the United States granted on the 1st of May, 1900, under No. 648,467; and it has for its object to provide a molded boat the shell whereof is without seam or joining and consists of saturated felted fabric. The invention may be said, briefly, to consist in laying upon a mold a blank consisting of saturated felted fabric, drawing the end portions of said blank down over the ends of the mold, and fastening them to a part of said mold which is in a position relatively to the gunwale-line to cause the blank to lie taut upon the said ends of the mold. The blank is then smoothed tightly upon the mold from the ends to the midships and fastened to said part for this purpose'as the smoothing progresses, thus causing all the slack to be taken up and a complete intact felted-fabric shell without seam or joint to be formed. The molded shell while still upon the mold is then kiln-dried, after which it is removed from its mold and is ready for lining and furnishing, as usual.

For full comprehension, however, of my invention reference must be had to the accompanying drawings, forming a part of this specification, in which like symbols indicate the same parts, and wherein- Figure 1 is a plan view of the blank from which my improved boat is molded with the mold dotted beneath it. Fig. 2 is a perspective View of the blank and mold with the boat partially molded. Fig. 3 is a perspective view of the complete molded boat. Fig. i is a transverse sectional view of the molded boat upon the mold, and Fig. 5 is a transverse sectional view of the boat removed.

In order that my invention may be clearly understood, it is necessary that besides disclosing my improved boat itself the method of making same should be set forth.

The boat consists of a single piece of saturated felted fabric molded into boat form without seam or joint and is illustrated particularly in Figs. 3 and 5.

To construct my improved boat, the blank 6, of felted fabric, is first saturated with a solution of shellac or other suitable substance and then preferably allowed to stand for sufficient time to allow the superfluous solution to be absorbed, the time required varying with different thicknesses of felted fabric. The blank is then stretched over the mold, the ends being first attached by tacks or otherwise to the bow and stern portions of a rail 0 upon the mold (Z and which runs completely around the mold slightly apart from but upon or within the gunwale-line. After the endsare attached the fabric is smoothed back therefrom toward midships, as indicated by arrows in Fig. 2, the edge of the blank being attached to the rail as the smoothing progresses. Before the manipulation or smoothing process has reached Inidships the slack will have been completely taken up and the felt will be tight upon the mold. The boat and mold are then run into a kiln, where the former is thoroughly dried and when removed from the mold is ready for the usual fitting and furnishings. I prefer to set the keel f in a recess in the mold and attach the ends of the blank thereto first and independently of the attachment to the rail. When the completed shell is stripped from the mold, it is not detached from the keel, which remains an integral part thereof. The complete shell being without seam or joint is less liable'to leak and more durable than the usual boat-shell and can be more quickly manufactured.

What I claim is as follows:

1. In the manufacture of a boat first saturating a single sheet of heavy felted fabric with a resinous substance, then applying said sheet to a mold or pattern which contains a separable keel then attaching the ends of said blank to the ends of said mold, thensmoothing said blank upon the mold from the ends toward midships and attaching the edge of the blank to the mold as the smoothing progresses, then drying said fabric and finally removing it from the mold, substantially as described.

with a resinous substance, then applying said sheet to a mold or pattern which contains a separable keel, then drawing the ends of said blank over the ends of the mold and attaching same to the ends of the keel, then smoothing said blank upon the mold from the ends to- Ward midships and attaching the edge of the blank to the mold as the smoothing progresses, i

then drying said fabric and finally removing it from the mold, substantially as described.

In testimony whereof I have afiixed my signature in presence of two witnesses.
