\ COLLAPSIBLE BOAT.
Application filed June 11, 1925. Serial No. 36,377.
This invention relates to boats of the kind which are made of flexible air-tight material and which are adapted to be inflated for use, and which may be deflated to permit the boat to be folded and stored in a small space, and the invention relates'more particularly to boats of this kind comprising one or more tubes or cylinders which are inflatable-and which form the sides of the boat and which are connected at their lower portions by means of a sheet of waterproof material so that the water may be kept out of the interior of the boat.
The objects of this invention are to improve in general the construction of boats of this kindso that these boats will be of extremely light weight without sacrificing strength or durability; also to provide a boat of this kind with seats of improved con struction, which form a part of the boat itself also to provide means of improved construction for securing the seat to' the inflatable tubes or cylinders of the boat; also to provide a boat of this kind of improved and novel form whereby the bow of the boat when in use will be raised or elevated to prevent splashing of the interior of the boat and to render the. boat more 'seaworthy; also to provide a boat of this kind with valves of improved construction which facilitate the inflation and deflation of the boat; also to improve the construction of boats of this kind in other respects hereinafter specified.

-ll1/l)llll(ll0tl(lS 15. and the side cylinders or tllllts extend from the bulkheads to bulkheads 16. The front end of the boat, in the particular construction shown, consists of two converging tubes or cylinders 17 which are connecied by a rounded nose portion 18, but it will be understood that the boat may be substantially rectangular in form, if desired, in which case the front piece Would be similar in construction to the rear tube or cylinder 10, or if desired, the rear tube or cylinder of the boat may be replaced 'by a cylinder or section similar to the bow section 11 shown in the drawings, in which case a boat with two sharp or converging ends would be formed. A boat of any other shape may be used without departing from my invention.
Each of these cylinders or tubes is preferably made of a piece of material which has been suitably treated or coated to make the same impervious to air or gas,a balloon cloth consisting of several plies of material with the threads running in different directions and cemented or vulcanized together being preferably employed. It will be understood, of course, that each of the sections of the boat is provided with an air inflation-tube, so that the several sections are separately deflatable and inflatable, whereby apuncture or damage to one of the sections causing a leak of air would not interfere seriously ",with the manipulation or buoyancy of the boat. The corner portions and the nose of the boat may be made of a plurality of separate sections 19 suitably cemented together in any desired manner. The lower portions of the various cylinders or tubes of theboat are connected by means of a bottom 20, which is made ofwaterproof material, and the edge portions of which are cemented or otherwise suitably secured to thebottom portions of the cylinders or tubes, so as to form a watertight joint therewith. The outer edges of the bottom 20 of the boat extend upwardly slightly beyond the extreme lower portion of the tubular sides of a boat, so as to protect the tubular sides against abrasion when the bottom of the boat strikes the shore or when the boat is resting on the ground, and to aiford a secure joint between the bottom and the cylinders or tubes. By
means of this arrangement the bottom of the tubular sides of the boat are afforded protect on against the usual wear'and at the same tune the weight of the boat is not excessively increased.
The boat may be provided with one ormore seats or thwarts 22 extending transversely of the boat and which are made of flexible material and secured to the tubular sides of the boat, so that when the boat is folded, the seats, as well as the bottom of the boat, may be folded together with the tubular sides. The seats in the particular" construction shown are secured to the up-. per. edges of the tubular sides of the boat, preferably by cementing, vulcauizing, or in any other suitable manner, and the ends of avoid stretching of the same due to the vwelght of a person, one or both of the edge portions 24 of each seat 22 are reinforced by means of a canvas strip 25, which is preferably covered by the material of the seat by folding the edge portion of the piece 23- of the seat around the reinforcing canvas strips 25. This-canvas strip 25 should be made of sufficient strength so that it will not stretch during the ordinary use to which it is put. By reinforcing .the seats in this manner, the weight of the seat is not materially increased, and the canvas strips of the seat are protected against moisture by the waterproof material which encloses the same and prevents them from' becoming soaked with water and deteriorating or rotting when the boat is stored away.
In order to prevent the portions of the seats and the bottom of the boat which are secured to the tubular sides of the boat from pulling away from the sides, for example, when the boat is folded, the construction which is illustrated in Fig. 7 is preferably employed. According to this construction, a strip of material 26 is cemented or etherwise secured into the angle shaped recessformed by the securing 'of the bottom to the tubular sides of the boat, this strip conforming to the angle .between the tubular side and the bottom when the boat is in use, and
extending to a short distance along the inner side face of the tubular structure, so that one flange or side of. each strip is seof the boat and the other side or strip to the bottom ofthe boat. A similar strip 27 is secured in the acute angled recess formed by the seat and the inner-side of the tubular structure. Thesestrips 26 and 27 increase very greatly the resistance to separation of the seaiit or cemented connection between the seat or the bottom of the boat from the tubular sides thereof. By arranging the seats across the top faces of the tubular structure andthe boat bottom across the lower faces of the tubes, the tubular structure is braced so that it will retain its correct shape under different load conditions, and the strength of the boat is also increased.
-The arrangement of the seats in the boatis of importance. The front or.bow seat is preferably located a considerable distance aft of the bow of the boat asv clearly indicated in Fig. I, and the result of this arrangement of the seat with reference to the nose of the boat is that whena person is seated on the front or bow seat, the bow of the rboat willv be bent upwardly forward of the seat, due to the upward pressure exerted by the-Water acting on the bottom of the front portion of the boat, and due to the elasticity of the tubular sections of the boat.
This curving up 'of the bow of the boat is important in that it renders the boat more seaworthy, and also prevents splashing of the water against the back of the person rowing in the front seat. The rear seat is preferably arranged to extend toward oppositesides of the two rear bulkheads 15 and by this arrangement of the rear seat,a puncture of the two side tubular sections or of the use of the seat, since each end of the rear the rear section of the boat will not impair seat is supported by two different tubular sections of the boat.
Inview of the fact that comparatively low air pressure ais sufficient to inflate the boat and-to keep the same in an operative condition. means are preferably provided whereby the air may be rapidly. pumped into the various tubular sections of the boat or discharged therefrom and preferably the air is pumped intothe tubular sections by means of an ordinary hand operated bellows, which is capable of delivering a large quantity of air at low pressure. In'order to make possible the use of a hand operated bellows for this purpose, each of the tubular sections of the boat is provided with a valve capable of operating under the low pressure delivered by the hand operated bellows. In the par- I ticular construction shown, see Figs. 3 and 4,;
this valve is 'made of a disk- 30 of relatively soft rubber or rubberized fabric which -is held in place against the inner. face of the fabric 31 of which the tubular sections are made by means of a tape or strip 32, the
inner face of the fabric 31 so that this strip 7 serves to loosely hold the valve in its operative position over the hole or opening 33 in the tubular section,and the sides of the valve which are not covered by the tape can readily be lifted by air pressure from a pump or bellows, and are held in seated or closed position by the air in a tubular section when the section is inflated. A valve of other construction may be used if desired. On the outer portion of the f..bric 31 an inflation sleeve 34 is secured towhich the hand operated bellows or other inflation device may be connected. This sleeve may be made in any suitable or desired manner, and is provided at its inner end with a plurality of outwardly flaring strips or portions 35, which are secured between two annular fabric or rubber pieces 36 and 37, which are in turn secured to the outer face of the fabric 31 of the tubular section, and surrounding the inflation opening 33.
. The outer end of the sleeve may be provided with a suitable stopper 38 for closing the end of the sleeve to prevent escape of air through the valve, the stopper shown being adapted to be secured into a threaded bushing 39 secured in the outer end of the inflation tube 34. When it is desired to inflate the boat, it is only necessary to insert the nozzle of the hand operated bellows into the end of the inflation tube 34 and then to operate thebellows. When it is desired :to discharge the air frond the interior of the boat,
it is only necessary to insert a pencil or small stick against an edge portion of the valve to move the valve from its seat and thus permit the air'to discharge. The valve isprade of very flexible material so that very little. air pressure is necessary to raise the same from 1ts seat.
The seams between adjacent pieces of material which are in the nature of lap seams are preferably made as shown in Fig. 8, in which 40 represents one piece of material and 41 another strip, the edges of which are overlapped and secured together as shown at. 42. A strip of tape 43 is then secured over the edge of the outer piece of the lap joint, for example, the outer edge of the piece 40 in the construction shown in Fig. 8, and this strip 43 is-cemented or otherwise secured over the outer edge oft-he piece 40 so that separating of the seam or leaks in the seam are prevented. Seams of this kind are employed wherever two edges of material overlap and are not illustrated in Figs. 1, 2 and 6 because of the. smallness of the scale on which these figures are drawn. r
The bulkheads are preferably. formed at the joints between adjacent tubular sections of the boat, and a construction is illustrated in detail in Fig. 5 in which the overlapping portions are secured by means of a joint closed by a tape 43, as indicated in Fig 8.
Another strip of material 45 is then secured over the inner face ofv the lap joint. A pair 'of annular bulkhead holding members 46 and 47 of angle shape are secured to the strip 45 in such a mannerthat inwardly extending flanges of the annular members extend into contact with each other. these flanges forming the securing means for the bulkheads themselves. These bulkheads are made of a pair of disk shaped pieces of material 48 and 49 arranged face to face and having their outer edges extending in opposite directions to form flanges as indicated at 50, 51, the portions of the disks 48 and 49 adjacent to the edges thereof being secured on the outer faces of the inwardly extending flanges of the bulkhead holding members 46, 47. The bulkhead described is of light construction and readily foldable and at the same time posseses ample strength and is easily constructed. Bulkheads of any other construction may, however, be employed if desired. a
.represent car locks made of loops of rope or other flexible material, the ends of which are suitably secured to the side tubular sections, preferably by means of cover pieces 56. Oar locks of other suitable con- 'stru'etion may be employed if desired.
Boats of this kind can be folded in compact form so that they can be readily carried in a comparatively small hand bag. By
means of the structure described a boat capable of carrying two.0r three men, including paddles, bellows and carrying case, weighs approximately ten pounds, and can be inflated and made ready for use in two or three minutes. It will'be obvious that the boat may also be used as a' mattress or cushion when inflated and inverted.
