members

12, 13 for body portion 1. '1

The body'portion 1 is formed of impeiwiousm-aterial, such as canvas, is "of oval-shaped contour andpprovided at each end with a pair of oppositely disposed triangular shaped flaps 14,715. The pairs of flaps are oppositely of the flaps of each pair is formed inprox'-' imityto 'a' longer edge thereof with a series of spacedopenings :16. The/body portion l w pairs of intermediate sections which are interposed between the centralsection -20 and the outer sections 18, 1'9. The sections of each pair of intermediate sections are indicated at 21, 22 and the latter is of greater lengththan theformer. The sectiOnQEZ h-as itstop edge provided in proximity to the section 21w'it-h- I a groove 28. The sections-22 of the pairsof intermediate sections .arehinged to the-central section 20, as at 24,, 25.

sections

40, 41. The sections 3 posite directions with respect to the bevels 30. Each side of each of the outer sections is rabbetted as at 31, 32 and 33. Each outer section isformed with spaced, transversely extending openings 34. Each outer section is further formed with a horizontally disposed opening 35 having a threaded wall. The outer ends of the

sections

18 and 19 are beveled as at 36. The side members are of like construction, with this exception that the

members

3, 8 are of greater length than the members 4, 7 and the members 5, 6 are of less length than members 4, 7. The

members

3, 4 and 5 correspond in length to the length of the members 8, 7 and 6 respectively. The construction ofeach of its side members is best shown in Figures 7 and 8 and each of which includes a central section 37, a pair of

intermediate sections

38,39 and a pair of

end sections

40, 41. The inner ends of

sections

38, 39 are hinged as at 42, 43 to the ends or" section 37, and the outer ends of

sections

38, 39 are hinged as at 44, 45 to the inner ends of 7, 38, 39, 4G and 41, when extended have lap joints therebetween, as the inner ends of

sections

40, 41, both ends of

sections

38, 39 and both ends of section 37 are provided with reduced apertured extensions as indicated at 46, Figure 10. The apertures in said extensions register when the side member is extended, and ex tending through each pair of registering apertures is a removable latching device 47,

see Figures 1 and 2. The outer end of section 40 andsection 41 is enlarged as at 48, beveled as at 49 and apertured as at 50. The sections 38, 39are apertured as at 51 and the section 37 as at 52.

The

rib members

9, 10 and 11 are of like.

construction, with this exception that the member 10 is of greater length than the members 9 and 11 and these latter correspond in length. The construction of the rib members I is best shown in Figures 17, 18, and 19 and by reference thereto each rib member includes a central section 53, a pair of

end sections

54, 55 and two pairs of intermediate sections.

The sections of one pair are indicated at 56, 57 and the sections of the other pair at 58, 59. The ends of each of the

sections

53, 56, 57, 58 and 59 are oppositely beveled- The inner ends

ofsections

54, 55 are beveled. The sec- .tion 53 is hinged to

sections

57, 58 as at 60,

61. The

sections

56, 57 are hinged together as at 6.2. The

sections

58, 59 are hinged together as at 63. The mner ends of

sections

54, 55 are hinged to the outer ends of

sections

57, 59 as at 64, 65. Each of the

sections

53, 54, 56, 57, 58 and 59 is formed with a central open The

sections

57, 58 and 59 have enlarged ends to provioe grooves 66 and the

sections

54, 55 are mortised as at 66".

Each tensioning member or element, best shown in Figures 2 and 16, comprises a bar 67 of triangular cross section having a rounded lower end 68. The inner side of the bar 67 7 is formed with a socket 69 for the reception of an adjusting means 69 therefor in the "form of a threaded bolt which threadedly en- The

side members

3 and 8 have attacned to their inner laces spaced pins, eyes orhooks 71 which coact with lacin g members 72, 7 3 for securing the body portion 1 to the frame. Laoing

members

74, 75 are employed for connecting the

flaps

14 and 15 together over the top at the bow and stern of the boat. The

openings

16 and 17 in the body portion 1 are provided for the passage of the lacing members.

When the framing is set up the keel memher 2 isfirst laid. The rib members are then mounted in the grooves of the keel member and secured to the latter by the removable holdfast devices 76. The side members are positioned in the grooves and mortises of the rib members and detachably connected to the latter by removable holdfast devices 77. The

sections

40, 41 of the side members are also mounted'in the mortises of the

sections

18, 19 of the keel member and detachably connected therewith by the removable holdfast devices 78. The bars 67 are arranged to 0ppose the

sections

18, 19 ofthe keel member 2 and adjustably connected to said sections by the bolts 69. .T he body portion 1 is then laced to the framing and tensioned.

What I claim is:

1. A collapsible boat comprising a framing formed of a keel member formed of a series 01 hinged sections, a series of rib members seated in the keel member and formed of a series of hinged sections, a series of side members seating in the keel and rib members hinged sections, a series of rib members seatmg 66. The hinge connections between the sections are countersunk.

ed in the keel member and formed of a series of hinged sections, a series of side members seating in the keel and rib members and formed of a series of hinged sections, means for detachably connecting said sections together, a flexible body portion formed of impervious material, means for detachably securing said body portion against the sides, ends and at the ends of the top of said frame,

and tensioning means for said body portion positioned at the ends of and exteriorly of the keel member and adjustably connected to the latter.

3. A collapsible boat comprising a framing formed of a keel member formed of a'series of hinged sections, a series of rib members seated in the keel memberand formed of a series of hinged sections, aeseries of side members seating in the keel and rib members and formed of a series of hinged sections, means for detachably connecting said sections to gether, a flexible body portion formed of impervious material, means for detachably securing said body portion against the sides, ends and at the ends of the top of said frame,

and means for latching the sections of each of said side members from movement when connected to the keel and rib members.

4. A collapsible boat comprising a framing formed of a series of hinged sections, means for detachably connecting said sections together, a flexible body portion formed ofimpervious material, means for detachably securing said body portion against the sides,

endsand at the ends of the top of said frame,

tensioning means for said body portion positioned at the ends of and exteriorly of the keel member and adjustably connected to the latter, and means for latching the sections of each of said side members from movement when connected to the keel and rib members.

In testimony whereof, I afiix my signature hereto.
