SPECIFICATION forming am of Letters Patent No. 648,467, dated May' i, 1906'.

d Applicationled` April 17,1899. Serial No. 713,409. (No model.)

' declare that the followingis a full, clear, and

exact description of same. l

My invention relates particularly to the art or manufacture of boats, canoes, and the like,

l and has for its .object .to provide a -molded boat and one that will be more durable than if constructed by building up and joining together separate sections of material, besides being constructed in'less time than has been possible heretofore. To this end I saturate a fabric, either in one piece or in a number The preferred manner of carrying out my invention is to saturate a sheet of felted fabric in a solution of shellac. vThis sheet while wet is applied to anpattern or mold either by laying it upon or stretching it over the mold,`

and the ends of the sheet are joined together over the bow and stern portions or such ends folded and joined, the shell thus molded then being allowed to dry and trimmed and furnished, as usual, after which it is ready to take the Water. For full comprehensiomhowever, of my invention-reference must be had to the accompanying drawings, in which like symbols indicate the same parts, and where- Figure l is a perspective view of a boat in course of construct-ion upon its mold. Fig. 2 is a rear end view of the lcompleted boat. Fig. 3 is a transverse sectional View taken about midway of the length of the boat; and Fig. 4t is a similar view to Fig. 3, but showing the shell upon the mold. l

The pattern b may beof any desired contour and preferably has a keel-strip c, rectangular in cross-section, anda series of strips d of small semicircularcross-section laid upon the portion thereof from which the bottom of the boat is molded. The felted fabric e is saturated, preferably, by immersion in shellac, which renders it While wet perfectly pliable lifdesired, be pressed into the interstices be'- tween the keel-strip c and the strips d, which are located equidistant apart and on each side of said keel-strip, and betweensaid strips d in order to impart asuperior finish, yet I have found this quite unnecessary, as the natural weight of the saturated fabric will cause it to sinkinto all recesses. The edges of the folded portions of the end f of the sheet that envelops the bow portion of lthe mold are joined molded is thenallowed to thoroughly dry, the

stretcher-strips 7L are then removed, and the shell, which when dry although slightlyl elastic is comparatively rigid, can 'then be re- A moved from its mold and after `receiving the flooring, seats, andjusual trimmings is ready to take the Water. I I

I prefer in `heavy boats to allow the keelstrip c and strips d to remain in their places embedded in the felted fabric in order to provide means whereby the flooring, foot-rests, and the like may be secured in place, although in light boats or canoes the corrugations formed by the strips 7L and keel molded by the keel-strip will impart suliicient rigidity to the bottom of the craft.

It is obvious that the time expended in stretching the sheet over the mold or pattern and forming the joint at eachfend (as the saturation of the sheet and drying of the shell require no attention) is all that need be expended inthe construction of the shell of a boat, canoe, or the like according to my inventiou. Consequentlyany one of average intelligence can manufacture avcraft of this nature in about one-tenth the time it has heretofore taken a skilled boat-builder to build ICO having-a resinous substance appliedv thereto,`

Substantiallyas described; 'l v onefof the usual type. l It is further` ob'vicus-V .-that if apunt form is desired both ends can be constructed according to my descrption'of 7 the constrnction'lof the stern or both endsn- .iron

Without departing from the spirit vof .my invention. l e

lWhile `I lhave described indetail the fullyconstructed boat, I do net herein claim saine,- as such forms the subject-matter of la separate application.
