BOAT.

Specification of Letters Patent.

Patented Aug. 7, 1906.

To aZZ whom it may concern.-

Be it known that I, BERNT TENNESON, a citizen of the United States, and a resident of the city and county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Boats, of which the following is a specification.

My invention relates to improvements in folding boats, and more particularly to imrovements in that class of folding boats havmg an inner part or frame constructed of hinged sections adapted to fold lengthwise and an outer covering of canvas or other suit able waterproof flexible material; and the objects of my invention are to furnish an improved meansfor securing the upper sides of the canvas cover to the wooden mner part of the boat, to furnish an improved means for detachably securing the thwarts to the boat, and to furnish an improved means for securin in place a detachable square stern.

t e accompanying drawings, forming art of this specification, and in which simiar letters of reference indicate similar parts throughout the several views, Figure 1 is a top plan view of my improved folding boat; Fig. 2, a section of Fi 1 on line AA; Fig. 3, an enlarged section 0 part of one side of the boat, showing the means for attaching one end of a thwart thereto; Fig. 4, an enlarged section of part of the other side of the boat, showing the means for securing the other end of the thwart; Fig. 5, a perspective view of keeper for the end of the thwart shown in Fig. 3; Fig. 6, a perspective view of keeper for the end of thwart shown in Fig. 4; Figs. 7 and 8, enlarged views, partly in section, of opposite ends of a thwart; Fig. 9, a perspective view, looking toward the stern, of t e square stern and means for securing it to the sides of the boat; Fig. 10, a plan view of a modified thwart-securing means, the thwart being shown in full, while parts of opposite sides of the boat and the kee ers are shown in section; Fig. 11, alongitu inal section of part of the stern end of the boat, showing means for securing square stern; Fig. 12, a transverse section of the boat when folded; Fig. 13, a section of upper part of canvas cover, showing hole through which oar-lock plate may be assed.

a is the kee b b the bottom, and c c the sides, of the boat. These parts are preferably made of wood and are hin ed together, so that the sides 0 may be folde over on top of the bottoms b and the latter 'moved up at 'right angles with the keel, as shown in Fig. I 12, in order that the boat may be reduced to the smallest size for either stowing or ship- 1n p T he manner of constructing the keel, bottom, and sides of the boat, as well as the means for securing these several parts together, being old and well known, I make no claim thereto, nor do I deem it necessary at.

this time to more fully describe them.

dis a canvas cover, which not only insures the boat being water-tight, butwhich also serves to protect the wooden part of the boat from injury when in use or when being shipped. At one or both ends the cover asses over the top of the boat, and in order that it may be readily put in place or removed it is secured at this point by a lacing e, Fig. 1. The cover with the laced end or ends is in itself old but my method of securing it in lace along the gunwales is new. At several p aces near the upper end of the cover I cut holes f, Fig. 13, and pass through these holes a corresponding projection carried by the upper inner sides of the boat. Then through the projection I ass a suitable key to keep the cover from l aving the projection. The projections that I referably use for this purpose are the soc ets g, which carry the oar-locks h, the oar-lock serving as the pin to prevent the withdrawal of the canvas from the sockets.

Boats of the class described are held in their open position by the thwarts alone, and hence 1t is desirable that a thwart-fastening be used which will not be liable to come unfastened. To this end I secure upon 0 posite sides of the upper portions 0 c of the oat keepers t j. (Best shown the former in Fig. 5 and the latter in Fig. 6.) The keeper #5 is furnished with a slot la, and the end of the thwart l, which rests upon this keeper, is furnished with a hook m, Fig. 7, which is adapted to pass in the slot 7: and engage the metal to the rear of the slot. 7 The opposite end of the thwart Z carries upon its under side a spring-operated bolt n, which when this end of the thwart rests upon the keeper j is adapted to engage the under side t ereof. This end of the thwart also carries depending projections 0, which are adapted to enter corresponding holes p in the keeper 3'.

The hook m when in engagement with the keeper 4. prevents one end of the thwart from being lifted or drawn away from this keeper, while the projections p and the bolt n serve the same purpose for the other end of the thwart; but by retracting bolt 11. the end of the thwart carrying the bolt may be lifted clear of the keeper 7, and a further lifting of this end will place the hook 'm in position to be withdrawn from keeper '5.

A bow-thwart is shown in Fig. 10. In this case the keepers 1" s, secured to the sides of the boat, are furnished each with a horizontal slot t. The slot t in the keeper 1* is open at the forward end and closed at the after end. The slot tin the keeper 8. is open at the after end and closed at the forward end. The thwart is put in place by entering diagonal corners of opposite sides in the open ends of the slots and forcing it in place. At the forward end of the boat spreading of the sides is prevented by the laced top of the cover, (shown in Fig. 1,) and hence other fastenings are not necessary.

The square stern u of the boat is shown in Figs. 1, 9, and 11. At the central part of its inner lower end the stern 11, carries a hookshaped casting o, and at the rear end of the top of the keel a is carried a mating. casting w. By moving the stem to. either side the caste ing i) may be disengaged from casting w; but when these castings are in engagement they prevent any upward movement of the stern. 01: represents loose butt-hinges one side of which are secured to the upper sides 0 of the boat and the other side of which are secured to the stem 11.. When the pins y of these hinges are in place and the castings '0 w in engagement,

the stern u is securely locked to the sides and keel of the boat. If the pins y be withdrawn and the canvas cover be removed from the stern of the boat, the stern is in condition to be moved so as to unlock the castings 'v w, after which the thwarts may be removed and the boat collapsed, as shown in Fig. 12.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a boat, in combination, a colla sible frame, projecting rowlock-sockets carried by the upper inner part of said frame, and a can'- vas cover the upper edges of which are furnished with holes adapted to pass over the rowlock-sockets.

2. In a boat, in combination, a frame 001-. lapsible lengthwise, keepers laced opposite one another, one on each oft e inner sides of the boat, a thwart, a hook carried by one end of the thwart adapted to engage one of said keepers, a spring-bolt carried by the other end of the thwart adapted to engage the under side of the other keeper, and projections carried by the latter end of the thwart adapted to ass down through corresponding holes in said latter keeper.

3. In a boat, in combination, a frame collapsible lengthwise, a square stern, mating hooks, one carried by the keel of the boat and the other by said stern, adapted to secure said stern and keel together, and loose butthinges one of the sides of which are secured to said stern and the other to the sides of the boat, adapted to secure said stern and sides together.
