COLLAPSIBLE BOAT.

Specification of Letters Patent.

Patented Dec. 31, 1918.

Application filed. March 28, 1918. Serial No. 225,241.

To all whom it may concern:

Be it known that we, JACK PRESAMENT and ABRAHAM PROVISOR, subjects of the King of Great Britain, and residents of the city of WVinnipeg, in the Province of Manitoba, Canada, have jointly invented certain new and useful Improvements in Collapsible Boats, of which the following is the specifi cation.

The invention relates to improvements in boats and the principal object of the invention is to provide a light collapsible boat particularly adapted for hunting and similar purposes and one which when collapsed can be readily transported and in a compact form from place to place.

A further object of the invention is to arrange the construction of the boat so that it can be easily and quickly extended or collapsed and which when extended presents a more or less rigid structure consistent with the purpose for which it is designed.

With the above objects in view the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described and later pointed out in the appended claims, reference being had to the accompanying drawings in which Figure 1 represents a side view of the complete boat in the extended form.

Fig. 2 represents a plan view of the same.

Fig. 3 represents a central view through the boat and looking forwardly partly in section.

Fig. 4 represents more or less diagrammatically a portion of the boat as it appears when being folded or collapsed/ Fig. 5 represents an enlarged detailed view of the bow of the boat with the covering removed.

Fig. 6 represents the boat as it appears folded and resting on the stern.

Fig. 7 represents a perspective viewof one of the gunwale hinges.

Fig. 8 represents a plan view of one of the beam hinges.

Fig. 9 represents a side view of the frame work showing the partially collapsed position of one of the beam sections.

Fig. 10 represents an enlarged detailed side view, part in section, of the joint formed between the inner ends of the locking bars.

In the drawings like characters of reference indicate corresponding parts in the several figures.

,- '1 and 2 represent the-bow and stern-ribs of the boat which are U-shaped in form and are preferably made from well seasoned wood.

3, 4:, 5 and 6 represent intermediate U- shaped ribs of varying size spaced a suitable distance apart and appearing between the bow and stern ribs. The lower portions of the ribs are connected together by a sec tional jointed beam 7 which runs from the front to the back of the boat. The several sections of the beam between the several ribs are identical in construction, each comprising two pieces indicated at 8 and 9 which are hinged together at 10 in a manner to break joint upwardly and have their extending ends hinged to the ribs as shown at 11 and 12. The hinge indicated at 10 is shown best in Fig. 8 where it will be observed it is formed from two wings 13 and 14 connected by a pivot bolt 15, the bolt being supplied at the ends with pairs of opposing lugs 16 and 17 which carry horizontally disposed pivot pins 18 which pass in the direction of the beam and are for a purpose later ex plained.

The hinges connecting the beam section to the ribs are two winged ones permanently fastened to both the ribs and the section and arranged so that when the sections are buckled upwardly their outer ends can turn in respect to the ribs (see Fig. 9).

The ends of the ribs are all connected together by what we might term sectional gunwales 19 and 20, one at each side and the gunwale sections 21, as they appear between adjacent ribs, are all similarly constructed and as now described.

Each section comprises two

pieces

23 and 24 hinged together at 25 in a manner to break joint inwardly and having their outer ends pivotally secured as indicated at 26 and 27 to the sides of the ribs such as by a strap hinge. The joint formed at 25 is made by employing a special hinge shown best in Fig. 7 where it will be seen that the pivot bolt 28 connecting the wings is provided at the lower end with a pair of opposing lugs 29 and 30 which carry a pivot pin 31 passing in the direction of the gunwale which is utilized for a purpose later described.

The upper ends of the stern ribs are connected by a permanent bowed strip 32 which with the rib and covering, later described, forms the stern of the boat.

The front rib 1; of the boat framework carries bow strip 33 which has the upper end thereofdirected backwardly and elevated considerably "above" the ends of "the rib and the lower end thereof fastened such 5 as by a strap hinge 34- to the front'rib so" that it actually forms afront extension, toffbe omparatively llght and can be read ly packedor collapsed for convenient-"carrythe beam; From the above arrangement it" will be obvious that the boat framework can be colfornied at 10 and "25111 the beam and" gun "-cl'osed in,that-isto sa y, brought toward each other: 'In 't'he extended'pos'ition of the boat frame "it is' necessary' to lock the several joints above referred to and this is accom- I plished ;by provi ding the locking bars collapsible ribs between the rigid ribs.
