IMPROVEMENT IN CO'LLAPSIBL'E BOfATrS.

Specification forming part of Letters Patent No. 148,661,v dated March 17, 1874; application filed August 2l, 1873.

and others who desire some portable means of conveyance on water. It is made up of a series of flexible ribs or poles extending from end to end of the boat, and fastened to stanehions connected with a keelson, so that the whole maybe extended to form a well-shaped boat, or may be collapsed, so that the ribs are brought into proximity with the keelson near them, and may be thus secured by a strap or other means, so that they can be very conveniently carried. Oars, seats, bottom, and the lateral braces employed to preserve the' form ofthe boat, may be contained in the boat when thus collapsed, and thus render it a very compact article.

In the accompanying drawing, Figure l is a top view of the frame extended to form a boat. Fig. 2 is a transverse section of itin the same condition. Fig. 3 is a longitudinal section of the same, representing it collapsed. Fig. 4 is a transverse section of the same collapsed, and Fig. 5 is a detail view of the connection between the ribs and a stanchion.

Similar letters of reference indicate corresponding parts throughout the several figures.

A A are the longitudinal ribs before mentioned. They are made of light wood, and are represented as being rectangular in their transverse section, but may be round poles, so long as they are flexible enough to be bent out to assume the shape of the sides of a boat. They are furnished at both ends with eyeplates a a, which are secured together by pivots or rods e e passing through them, whereby they are afforded liberty to turn or swivel, to prevent them from straining during their lateral flexure. The pivots e e are fastened to the opposite sides of two stanchions, B B, in position parallel, or approximately parallel, with their sides. These stanehions constitute the ends of the boat-frame, and are connected by links ff with the ends of the keelson G. These stanchions are thus connected with the keelson for the purpose of permitting their deflection outward to accommodate themselves to the extension of the ribs longitudinally, when they are collapsed into proximity with one their junction, are mortised into each other, and

pivoted together "at the middle of the boat by a. pivot, p, so that they can be folded together when desirable. When extended they are locked by a pin, s, passing through them both. It crosses the inner sides of the ribs at or about the middle, and is furnished with a number of pins or studs, g g, which fit into eyes c c provided on the several ribs, and thereby hold them in position, so as to preserve the shape of the boat. Gross-pins are applied to the ends of the aforesaid studs, be-

yond the eyes, to prevent them from slipping out and freeing the ribs. By this brace the ribs are not only preserved in their outward iiexure, but are prevented from extending farther than the brace, and are held laterally also. The seat H is arranged across the brace and is mortised at the ends to iit it. It is secured in position by pins inserted in the brace above it, and forms a stay to the brace, and affords additional strength to the boat. rIhe bottom of the boat consists of parallel pieces resting on two lower parallel ribs of the frame, and having cross bars pivoted to them, so that they both may be folded together, and will occupy but little space in the boat when collapsed. The boat-frame, thus constructed, is covered with canvas, or other suitable material, and may readily be eollapsed on the removal of the bottom, seat, and brace and pressure of the opposite ribs together. The oars, bottom, seat, and the brace can be all accommodatedwithin the boat thus collapsed. It may easily be made ready for use by removing,` the things from Within it and forcing its ribs apart7 and then adjusting` its brace, seat7 and the bottom.

One advantage of this frame is that the canvas is stretched tightly by the flexibility of the ribs.

The ribs might be jointed at some portion of their lengtl1,b11t innst7 of course, be connected by sonie device that will preserve their fiere ure from end to end. By this the. frame Will be rendered even more compact than before.

What I claim as my invention is- 'lhe combination of the links f f with the keelson and the stanehions, whereby the latter can accommodate themselves to the extension of the series of longitudinal ribs A Awhen the boat-frame is collapsed7 essentially as herein specified.
