reference being had tothe; accompanyingd-rasrings, forminga part oiithis specificar tion, and to-the reference nu-u'ierals marke'd thereon.

' present invention relates to boat building being more particul anly applicable to the construction oft canoes and it' has. for it-Skdbjbtt to improve and strengthen the docking atthe bow and stern 1n such: manner as to give greatei rigidity and durability to the seams and j'ointsinthis region particularly where the gunwales and pl anking are connected to-the stem. or stem posts. Tothese and other ends the inventionwresides incertain improvements andcomb inations of parts all as-will be hereinafter. more fully described, the novel features being pointed out in the claims at the end'Io-fv the specification.

In the drawings:

Figure 1 is a fragmentary side elevation of the bow of a canoe constructed in accordance with and illustrating one embodiment of my invention;

Figure 2 is a top plan view thereof;

Figure 3 is an enlarged detail section through the stem taken on the line 3-3 of Figure 1;

Figure 1 is a bottom plan view of the deck piece detached;

Figure 5 is an enlarged transverse sec tion taken on the line 5-5 of Figure 2;

Figure 6 is an enlarged transverse section on the line 66 of Figure 2.

Similar reference numerals throughout the several views indicate the same parts.

The weakest part of the canoe structure is in the region of the bow or stern where the post or dead wood, the gunwales and the side planking are brought together. This is also the region that receives the roughest treatment in the way of jars and sudden strains as in towing and in making landings where the stem collides with the Wharf or pier. In the practice of my present invention I make the deck piece by means of which these joints are strengthened so that it embraces and holds together the planking at the sides being preferably composed of" an integral met-al casting. having provisions for receiving: and tightly holding the vari ous elements t hat areto be joined together. My invention, as'before stated}: is applicable to variousboat structures but is particularly adaptable-to canoes because of their light construction and I will describe it as applied toithe bowof ja canoe.

Referring moreparticularl'y to the drawings 1 indicates the stem or dead wood. the outer gunwa le and 3 the inner gu-nwaleof: a familiar. type. of canvas cover-edcanoe. The ends of the greater portion of the trans verse ribs 4 to which the planking 5 is secured (which plankinginturn is covered witha canvasfi') are received -and fastened between theouten and inner-gunwalesQ and 3. I terminate thesegunwales at 'T and 8. respectively,the several. ribs 4 beyond the ends thereof being; attached only to the planking and? the latterbeing; secured as usual to thestem ordead wood 1. I then applyia deck piece 9".which. ispret-eiiabl'y a one piece aluminum casting with side I flan-gesilt)terminating atthe bow-1n a downward: extension 1:1 that: forms vai socket en.- compassing and extending a substantial distance downward over the stem 1. In connection therewith may be formed a perforated lug 12' furnishing an eye for the attachment of the painter. This outer flange 1O fits over and embraces the planking 5 from the terminal point of the outer gunwale 2 to the stem and prevents the bow and the otherwise unsupported ribs 4 thereof from spreading. At its rear end on each side the said outer flange is joined by an inner flange 13 forming an undercut abutment 14 for the end of the outer gunwale 2 that is shaped to tit it. The terminal 8 of the inner gimwale preferably extends somewhat beyond this on the opposite or inner side of the flange 13. At this point bolts 15 are passed through the outer gunwale 2, the planking 5, the flange l3 and the inner gunwale 8 securing them all rigidly together, the heads of the bolts being preferably passed through a common washer plate 16 on the outside. It will thus be seen that the spreading of the boat body in the region of the bow is absolutely prevented by the rigid flanges 10 of the deck piece While at the same time the gunwales are strongly attached to the bow structure without the complication of runnig them into the stem 1 ill!) llt) and weakening the latter by further cutting away the always slim mass of this member. As it is, the planking 5 alone is secured to the stem and is tightly held againt the same by the bow socket 11 on the deck piece be fore referred to. Preferably, a bolt 17 ispassed through the socket piece 11 and the stem 1 to increase the rigidity and constitute a forward securing element for the deck piece. The careful shaping and fitting of the gunwales at the joint or seam made with the stem and which ordinarily requires a high class of skilled boat building labor is eliminated while at the some time practically straight pieces may be used for the gunwales without preliminary steaming and shaping.

The appearance of the deck piece 9 is improved and it is also strengthened by a top rib 1S coincident with the projection of the rib 13 and by an under rib 19 in the form of a downwardly turned flange at the rear edge.

I claim as my invention:

1. The combination with a boat having a stem and side planking, of a metallic deck piece on the bow thereof having a socket portion fitting over and secured to the stem and having side flanges embracing the planking and gunwales overlapping the deck piece and disposed at opposite sides of the flanges and secured thereto.

2. The combination with a boat having a stem and side planking, of a deck piece on the bow thereof secured to the stem and having side flanges embracing the planking,

and a gunwale terminating in the deck piece and fastened thereto.

The combination with a boat having a stem and side planking, of a metallic deck piece on the bow thereof having side flanges embracing the planking and outer and inner gunwales terminating in and secured to the deck piece.

4. The combination with a boat having a stem and side planking, of a metallic deck piece on the bow thereof having side flanges embracing the planking and flanges on its under side and outer and inner gunwales terminating in the deck piece and fastened together on opposite sides of the last mentioned flanges.

5. The combination with a boat having a metallic deck piece embracing the bow thereof, of inner and outer gunwales terminating therein and secured together on opposite sides 01 a portion thereof.

6. The combination with a boat having a metallic deck piece on the bow thereof provided with side flanges engaging the sides of the boat to prevent them from spreading, the ends of said flanges being undercut and the deck piece being further provided with inwardly ofl'set flanges adjacent to such undercut portions, of outer gunwales having their ends fitting the said undercut portions of the deck piece and lying against the offset flanges, inner giniw'ales lying against the inner sides of the latter and fastening devices securing the gunwales and the flanges together.
