COLLAPSIBLE BOAT.

Specification of Letters Patent.

Patented Nov. 23, 1920.

Application filed Ri'ovember 20, 1919. Serial No. 839,494.

'10 all whom it may concern Be it known that I, Vroron HOLMSTROM, a citizen of Finland, residin at Detroit, in the county of Wayne and i tate of Michigan, have invented certain new and useful Improvements in Collapsible Boats, of which the following is a specification.

This inventionrelates to small boats, such as canoes and the like and one that may be collapsed and folded.

The object of the invention is to provide a boat that may readily be folded when not in use and which can be easily carried about by hand from place to place and be storedaway in a comparatively small space. 1

A further object of the invention is to provide a boat, the bow and stern of which may be folded inward andthe sides collapsed and locked together so as to completely conceal the bow and stern between the sides.

A further object of the invention is to provide a collapsible boat which when in folded position will have the general appearance of a satchel, suitcase or the like.

A still further object is in the provision of means for holding the vessel rigid when in extended or open position.

Other objects and aims of the invention, more or less specific than those referred to above. will be in part obvious and in part pointed out in the course of the following description of the elements, combinations,

arrangements of parts and applications of principles constituting the invention; and the scope of protection contemplated will be indicated in the appended claims.

In the accompanying drawing which is to be taken as a part of this specification, and in which I have shown a merely pre ferred form of embodiment of the invention:-

Figure 1 is a plan view of my improved boat, a portion of which appears in section, Fig. 2 is a longitudinal sectional elevation of the same, Fig. 3 is a cross sectional elevation of the same showing itexpanded and Fig. 4 is a perspective View of the same folded.

Referring to the drawing for a detailed description of the structure illustrated, to the ends of the bottom keel bars 2 and 3 two end bars, 4 and 5, which form the bow and stern, are hinged by hinge 11. Between these bars a canyas or waterproof covering A is secured by rivets or suitable means. Rigidly secured to the upper edges of the center portion of the boat are longitudinal bars 1, while pivotally secured to the forward and rear portion of the bow and stern respectively at 16 are arcuate bars 15. The covering A is secured about the bars 1 while at the bow and stern portions it is simply stretched across as suggested in Figs. 1 and Hingedly secured to the opposite longitudinal sides of the keel portion 2 by hinges 12 are a series of ribs 6, the free ends of which are adapted to snugly fit beneath the longitudinal side bars 1. To the upper end of these ribs is secured a keeper 17 and to the free end of the bars 15 is secured a spring pressed sliding latch 17 that engages with the keeper. Adjacent the upper end of the ribs and pivotally secured thereto by means of screw eyes 13 or any other suitable connection is a transversely arranged brace bar 9. The other end of these transverse braces is fastened to the ribs on the opposite side of the boat by a latch member 14. Timbers or uprights 10 are hinged at their lower ends to the inner side of the keel by hinges 8; These uprights are pivoted so as to fold inward and are prevented from backward movement by contacting with the surface of the keel. The upper end of these uprights is notched to engage with the transverse braces and thus forms a support for said braces. Snugly fitted against the inner side of the covering and'arranged between and end of these bars will lockingly engage the v upper end of the ribs 6. The transverse bars will brace thesides of the vessel and be supported by the upright members 10.

To fold the boat all that is necessary is to release the lock 17. Thereupon the top bars 15 will drop within the vessel. Then by releasing the latch 14 which permits thetransverse members 9 to be swung longitudinally beneath the side bars 1 and folding the upright timbers 1O inwardly against the keel 2 and 3 the said bow and stern portions may be folded inwardly, beneath the sides of the vessel. These sides may then be folded inwardly thereby embracing. the infolded ends as clearly suggested in Fig. 4 of the drawing, in which it will be seen that the compacted vessel has the eneral appearance of a satchel or suitcase. in order that the parts may be held in this collapsed position there is provided a cooperating'lock 18, secured to theupper edge of the sides. Suitable handles as indicated at 19 are also provided for carrying the collapsed vessel from place to lace;

I s many changes could be made in this construction without departing from the scope of the following claims it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative only and not in a limiting sense.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. A boat of the class described, having a keel portion, bow and stern portions hinged to said keel, collapsible side members hinged to the keel, transverse bars hinged at one end to the side of the vessel and adapted to embrace the opposite side thereof, hinged uprights secured to the keel for supporting the transverse bars, and pivotally secured bracing bars within the bow and stern portions adapted to cooperate with the upper portion of the collapsible sides for sustain-' ing said bow'and stern 1n extended position. 2. A boat of the class described, having a keel portion, bow and stern portions hinged to said keel, collapsible sides hinged to said keel, a longitudinal bar secured to the upper edge of said collapsible sides, bracing bars having one end pivotally secured to the upper end of the bow and stern the free end of said bars having locking en agement with the longitudinal bars, the ow and stem arranged for folding inwardly above the keel, the sides of the boat adapted to be collapsed upon the bow and stern, means 1 for holding the boat locked when in collapsed position and handles secured to the longitudinal bars for carrying the boat.

1 A boat of the class described, having a tee to said keel, collapsible sides hinged to said ortion, bow and stern portions hinged keel, a longitudinal bar secured to the upper edge of said collapsible sides, bracing bars having one end pivotally secured to the upper end of the bow and stern, the free end of said bars having locking engagement with the longitudinal bars, the bow and stern arranged for folding inwardly above the keel, the sides of the boat adapted to be collapsed upon the bow and stern and means for holding the boat in collapsed position with the longitudinal bars abutting each other. v

4. A boat of the class described, having a keel portion, bow and stern portions hinged to said keel, collapsible sides hinged to said keel, bracing bars having one end pivotally secured to the upper end of the bow and stern, the free end of said bars having looking engagement with the upper portion or the collapsible sides for sustaining said how and stern in extended position.

In testimony whereof I aflix my signa-' ture.
