Other and further objects and advantages of the present invention will be apparent from the following detailed description, drawings and claims, the scope of the invention not being limited to the drawings themselves as the drawings are only for the purpose of illustrating a way` in which the principles of this invention can be applied.
Other embodiments of the invention utilizing the same or equivalent principles may be used and structural changes may be made as desired by those skilled in the and art without departing from the present invention and the purview of the appended claims.

Fig. 6 is a cross sectional fragmentary perspective view of the larger one of the pontoons showing the storage position of the several parts of the craft of my invention stored therein.
Referring to Fig. 1 the complete collapsible boat of my invention is shown in an assembled position.
' The boat comprises, first and second, an elongated an- 2,916,748 Patented Dec. 15, 1959 FCC an opening 16 in the rearward end of Vthefirstvtube 10 for the storage of a major portion of the second or smaller tube 12 inside the rst and largertube 10.` It is preferable that the entire smaller tube 12 b e receivable in the larger tube 10, as shown in Fig. 5, with the larger tube 10 somewhat longer so as to extend beyond the smaller inner tube 12 suciently that the first resilient plug 20 can be received in the open end 16 of the first tube 10.
The first plug 20 s preferably of sufficient rigidity to hold its shape under normal conditions landhas the periphery of a shape complementary'to the interior wall 22 of the open end 16 of the first tube`10.
The first plug 20 is disposed in the open end 16 and is of a lesser size than the interior wall of the firstopen end under normal conditions so that the plug '20 is removable from the open end 16.
Means are provided for exerting pressure on the plug 2t) and such means can be referred to as the first exerting pressure means, which, as best seen in Fig. 2, comprises a conical inner portion 40 attached to a threaded or outer portion 42. The conical portion 40 has an inwardly tapered rearward end yto which the` threaded` shank portion 42 is attached.
The rst resilient plug 20 has a conical cavity48 on its forward or inner side, the cavity 48 normally receiving a part or all of the conical portion 40.
A pressure plate 50 is provided on the rearward or outer side of the first resilient plug 20.' The plate 50 isldisposed in a vertical'plane parallel with the outer or rearward end of the plug 20 said rearward end being disposed in a plane at a right angle to the axis ofthe elongated tube 10. f
The plate 50 has an opening 54 therethrough through which-the shank 42 extends, the shank 42 normally protruding rearwardly of the plate 50 ,and havigfa ywing nut 5S Vthreadedly disposed thereon.
The resilient plug 20 has a passage 60 of a shape for snugly receiving the shank 42, the passage extending from the conical cavity 48 to the rearward end of the plug'20. Y
When the wing nut 58 is opened fordrawing the conical portion 40 into the plug 20 the outer perimeter Aof the plug 2@ expands exerting sufficient pressure against the inner wall 22 of the bottom 10 as to providea watertightseal. v
To further'insure a water-tight seal it is preferred that the tube 10 be bent outwardly around its perimeter in preferably two places indicated at 62.
The outwardly bent portions 62 are preferably spaced apart forwardly and rearwardlyv of each other. The plug 2Q can have outwardly protruding raised portions 64 extending around its perimeter at two placesdisposed forwardly and rearwardly of each other and at positions adapted to engage in theoutwardly bent portion 62. This has the effect of further retaining the plug 2() against moving forwardly or rearwardly out of position.
If desired the outwardly protruding portion 64 oflthe plug 20 can be omitted inasmuch as the plug will force itself into the circular recesses on the inner side of the protrusions 62 from the pressure exerted on the plug by the conical portion 40.
The cone 40 can be of a strictly conical shape but is preferably provided with a slight curvature, on its outer' side and extending from its forward to its rearward end, as best seen in Fig. 2.
Referring to Fig. 5 the second and smaller tube 12' is shown inside the larger tube 10. The smaller tube 12 has a similar resilient plug which shall be given the numeral 20 because of its similarity to the plug 20.
However the plug 20 differs fromthe plug 20 if peripheral indentations are provided` in the plug 20, then these are numbered 64 and take the place of the peripheralprotrusions 64. The peripheral indentations 64 are correlated'and disposed complementary to protrusions 62' which extend around the periphery of the inner wall 22' of the tube 12 to the rearward end of the latter. The purpose of the indentation 64 and protrusion 62' is the same' as the purpose of their counterparts, theprotrusion 64 and the outwardly bent portion 62 of the pontoon 10.
Parts ofthe pressure exerting means of the plug 20' are substantially identical to their counterparts used with the pontoon and are given equivalent numerals except that the numerals are primed.
The tubes 10 and 12 are maintained in spaced apart parallelism, as seen in Figure 1, by a collapsible frame comprising a plurality of frame members 80 which are disposed transverse to the tubes 10 and 12 and which are secured to the tubes by straps 82 of U-shape and wing nuts 84.
The threaded bolts 86 are attached to and extend upwardly from the ends of attaching straps 82 and receive the wing nuts 84. The threaded bolts 86 are disposed through suitable apertures 88 in the respective frame members 80. AS best seen in Fig. 6, it is preferable that the straps 82 be formed of a resilient material, the normal shape of the straps 82 being straight for compact storage.
As best seen in Figure 1, the transverse frame members 80 are preferably of a channel shape in cross section, having an upper horizontally disposed center portion and downwardly extending vertical portions which latter have concave recesses 96 therein entering from the undersides thereof. The recesses 96 are disposed one in each downwardly extending side portion of each end of a channel and are of shapes complemental to the outer contour of the tubes 10 and 12 for snugly receiving the tubes therein.
The channel members 80 are preferably of various cross sectional sizes so that certain of the channels 80 will nest in others of channels 80 to make possible compact storage as shown in Fig. 6.
Referring to Fig. 6, one or more nested groups of channel frame members 80 are shown disposed inside the smaller or second tube 12.
The forwardmost one of the channels 80 is preferably provided with a large opening 90 at the center thereof. This opening can be used for many purposes. For example a mooring line could be attached to this opening or the opening could be used as part of an anchor point for a mast in the event it should be desired to sail the pontoon boat.
Referring to Fig. l, a cargo carrying portion 100 is provided and has a concave upper side 102 in which cargo can be placed.
The cargo carrying member is elongated and is adapted to be disposed. between two of the frame members 80 and the cargo carrying member 100 has horizontally protruding forward and rearward lips 108 and 110 which are adapted to extend above to adjacent ones of the frame members 80 for supporting the cargo carrying member 100.
The cargo carrying member 100 can be provided with apertures 110 along the edges of the horizontal lip portions thereof and bolts with wing nuts can be used as seen at 112 for attaching the cargo carrying member 100 to the frame members 80.
Referring to Fig. l, it will be seen that the downwardly extending portion of a cargo carrying member 100 can be provided with a rearwardly and downwardly inclined outward surface 120 on itsv outward side for placing a better surface to water splashing and for less rwater resistance.
The cloth upper portion 132 of the chair 130 has looped ends which are disposed about transverse frame .4 member portions 146 of the chair which latter are straight in their center portions with downwardly extending terminal ends, which latter are adapted to be received in sleeves 149 which are in turn fixed to the upper ends of the legs 134.
As thus described it will be seen that the transverse members 146 support the cover 132 of the chair when their ends are in the sleeve 149 and as best seen in Fig. 1.
Referring to Fig. 6 it will be seen that the cover can be rolled up around the chair frame members 146 for compact storage when desired.
Referring again to Fig. 1, a chair is there shown at 130. The latter is preferably of a folding type having a folding canvas top 132 and having legs 134 which latter terminate in vertically disposed end portions 138, best seen in Figure 6. Above the vertical end portions 138,
Referring to Fig. 1, a second cargo carrying portion 150 can be provided identical in all respects, if desired, to the cargo carrying portion, the portion 150 being disposed between the chair 130 and the rearwardmost frame member 30 to provide a platform on which the operator can stand when working with the outboard motor shown in dotted lines in Fig. 1.
The motor 160 can be mounted upon a motor bracket 168 fastened on the upper side of the rearwardmost frame member 80.
Pontoon boats will oat through the Water best if their pontoon boats 10 and 12 are bevelled on the undersides of their forward ends.
The way I prefer to do this is to provide underside surfaces of the bevelled portions 200 with a concave shape whereby one might say that they are uted. This has the effect of providing an uppermost forward end portion which is somewhat more blunt than pointed, but which has a wide area clear up to the forwardmost portion thereof on the top of which a person can stand at times. This construction also provides a greater strength at the forwardmost tips of the pontoon than would be the case if they were completely pointed.
l Referring now to Fig. 6, it will be seen that other equipment such as an oar 210 can also be stored in the innermost pontoon 12.
From the foregoing description, it is thought to be obvious that a collapsible pontoon boat constructed in accordance with my invention is particularly well adapted for use, by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof, and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice, except as claimed.
I claim:
