BOAT consrnnc'r'ron' Application filed March 10, 1931. Serial no. 521,587.,
This invention relates to a boat construction, the general object of the invention is to provide a strong, seaworthy, light and durable boat of less than one-half of the '5 Weight of the lightest boats of the same proportions as now built, which enables the boat to have more speed per horsepower; Another object of the invention is to provide a boat which is portable-in the smaller sizes of boats '10 and the planking of which is easily renewed when necessary, and one which has great resistance to the absorptionof water, and which can be shipped or transported in knockdown form. V
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafterfully described, illustrated in theaccomp anying drawings and specifical- 20 ly pointed out in the appended claims.
In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and inwhich :x
Figure 1 is a transverse sectional view' through portions of the boat constructed in accordance with the present, invention.
Fig.2 is a horizontal sectional view through the bow. of the boat. 7
-,,Fig. 3 is a view of the. stem member. Fig. 4: is a side view of said member.
- Fig. 5 is a view-partly in section showing how the seam battens and planks are connected to a frame part. 7 i l 7 As shown in these views, the frame or rib assen blyA, of the boat, is built of aircraft, seamlesssteel tubing 1 or aluminum alloy tubing of any desired cross sectional shape, the joints2of which are welded or brazed or connectedby gusset plates and bolts where necessa1'y, as shown' at 23. V The bottom of the frame or rib assembly is braced b-ythe.
59 The ribs or frame parts are formed.
the recesses 5 for receiving the seam battens 6. Each recess is sealed from outside air by a light sheet steel strip 7 welded or brazed in place. Nuts 8"areweldedor bra-zed to the inside faces of these sheets to receive the this keel is also held in place by machine bolts engaging nuts welded to therframe'part in the same manner as the battens and planks are connected with the frame part.
A stem is also' built of light sheet steel of substantially triangular-shapein cross sec-' tionor an other suitable shape with the oint 16. welde or brazed andthenuts 17 for the machine screws 18 are welded to the inner faces ofthe stem as shown iniFig. 2. a This stem is formed with the lightening holes 19 and at itsupper end is formed with the eye 20 for receiving a'rope or cable for tying the boat to the dock or the like.
V The stem flares outwardly to the proper angle at its lower end to properly engage the front end of the keel 13. The machine screws 18 of course hold the front ends of the planks V to the stem'as shown in Fig. 2, andthe'nose of the boat is preferably formed of' wood as shownat 21 inFig..2.i V a I The planking is treatedon both sides with a layer of aircraft fabric 22 treatediwith the usual do'peso as to completelyseal thewood and therefore the boat against gaining weight by: water absorptionr This also results -inH great'resist ance of hull against splintering by impact "forces and makes theme .of lighter planking possible- It also protects the boat against dryrot and marine growth andprovides a finish that does not have to be renewed periodically, like scraping andrepainting' of 1 loo seam;batt'ens;,,each: recess: beinglsealedby a e galvanized or otherwise treated for preventing rust." As the frame parts are sealed and treated against rust and the planking is coated with fabric and dope, the boat has long life and will outlive boats as now constructed. By using; the machinebolts and nuts,the boat can easily bee-knocked down for.
' transportation and assembled at the point of use, and when the planking is damaged, through-collision orotlierWise, such planking can be easily-renewed-through theuse-of the machine bolts for connecting the planking to the'frame.
It is thought from the foregoing descrip: tion that the advantages and novel' features ofrthe inventionavillibereadily apparent.
