Application-December 9, 1949-, 'Serial No. 132,149

'This invention relates "to an improvement in combination boat fenders andlife raft or life p'reservers.

'Itis an object of thepresent invention toaprovide .a boat fender constructed of-heavy canvas orthe'like formed-into a tubular easingin which is inserted an air cell to be inflatedfor'imparting a fieiiible formto thefender calculated'to absorb thelpounding or chafing normally imparted-toithe sides :of a boat when docked .or' lying side'by side with-other craft.

Another object of't he invention resides in the novlmannerof forming and closing the ends of the casing af er the air cell has beeninserted, whereby the air cellis entirly protected against injury or displacement either wholly or .par-

tially,.yet-being so arrangedasto be conveniently infiated'from'time to time as may be required.

*Aifurther objectof the inventionresides in the application of looped end =ropes through the end closures of the casing whereby the fender may 'be conveniently supported in position froma dock or the side of a craft or may serve as carrying handles.

A further and veryimportant object of thein ventionresides-ina heavy tubular canvas casing adapted -to be positioned over-the fender casing as ameans-to absorb Wear andlfurther as ameans --for supporting in looped form, a'liie line that .passes entirelyaround the horizontal circumferenceof the fender, with itsterminal ends-spliced together andheld against displacementat the ends of'the-fender byunderlying theffolded end :of the fender casing.

/ Another-distinct advantage in a fender of the above named character is that the air cell may abeformed ofa-conventional inner tube of vehicle tires by the addition a of a second inflation valve arrangedupon the'outer periphery or tread portion of the tube whereby thetube maybe distorted to a generally rectangular I shape for :in-

sertion intothe fender casing with the-additional inflation valve proieetingat one end for convenience. w

Other obvious advantages of the invention will readily present themselves during thecourse of the following description, reference being had to theaccompanying drawings wherein'l'ike charactersof reference refer to likeiparts throughout'the several views.

Rferringto the drawings:

Figure '8is a vi'ew'illustrating the fender air "cen.

Referring specifically-to the drawings, the numeral 5 designates a tubular, ,preferablylheavy canvas .casin'g,-open at its'ends. The .casing will be formed of a-sheet of canvas suitably united by stitching,notishown, andits ends will obviously be reinforced 'by hems and stitching, also not'sho'w'n. Each .open end adjacent its marginal edge lisprovided with Zfour. pairs .of diametrically oppositely arranged relatively small grommets 6 and l and two pairs .of rlativelylarge grommets '8, spaced outwardlyaof the grommets '5. A tubular heav-y'canvas wear shield 9, see particularly Figurel'is formed ..of;a sheet-of canvas united-at Til, by stitching, withLits .ends -open and suitably reinforced 'by stitching. Grommets LH are Ilongi- Itu'dinally .positioned in the I tube 9, asshown and upon-opposite diametrically disposed sides, .for a duallpurpose, to be described.

.An air cell 12, see .particularly Figure .8, "is .Tformed from a conventional vehicle tire inner tube. 'fl hemell 12 :carries the conventional air inflatiomvalve i3, aslis customary. A secondair inflation valve I4 is installed -.upon the-tube !2, but in zthis instance, is wmounted upon the tread portion; of thetube at a point directly opposite the valve I3. The air cell thus provided utilizesan air container thatcan bepurchased in-the open =market without the necessity-of specially formed cells and their attendant costs and serves with equal success.

ln the assembly ofthe device, the-'casingHJ-and tube 9 having been previously formed and assembled, --as inFigure '1 by merely slipping the tube :9 over the casing 55, the-cell"! 2. i i "compressed to generally rectangular shape, as in dotted lines in Figure 8 and is then insert-ed into the casing 5 and equidistantly spaced from the open ends thereof, with the valve M-projecting at one endi The casings 5 and 9 assume a generally rectangular shape in cross-section aft-er the cell is inserted. The terminal sides of the casing 55 are then folded inwardly, as-in Figure 2 and laced together bylacingsi 5, passing through thegrommets l, with the valve l protruding therebe tween. A life line 56, of. rope or other material, is threaded throughthe grommets E5 of the tube 9, passing around the folded ends of the-casing 5 and preferably under thelacings '25, with its terminal ends spliced together. The lacing of the line It through the grommets I Lform identicalloops H upon" both sidesof the fender, serving as hand engaging loops Whenthe device is used as a lifepreserverorlife raft. After the line I6 has been installedjthe top and bottom of the casing -.ends .is .folded inwardly, .as .in Figure 3 .andilacing T I 8 passed through thegrommets -6, .vviththe .terminalend o'ffthe valve 1 f4 .projecting 'therebetween. The .air cell is then Linflated through 'the ,vprojecting "valve J [4, Lto the T desired pressure. A suspension or support rope I9 is threaded through the large grommets 8 at both ends of the casing and the terminal ends thereof spliced together. The rope 69 forms a pair of loops at each end of the fender that may be used to support the fender from a pier or the side of a boat or may be used as a handle to carry the fender from place to place. The fenders may be used as life preservers or when used in groups with the end rope lashed together, forms an ideal raft and as such, may be arranged in pairs or various Ways dependent upon the size of raft desired.

It will be apparent from the foregoing that a very novel and highly efficient fender has been provided. The device is simple in construction, readily and easily assembled, is strong, cheap to manufacture and the air cell and wear absorbing shield can be readily and easily replaced as becomes necessary. Since the tube 9 will absorb wear due to pounding and chafing when the device is used as a boat fender, it follows, that this tube, used as a protective shield for the casing 5, will require replacement from time to time and this can be accomplished with a minimum of effort and cost, since it is not permanently attached to the casing 5 and adds greatly to the overall life of the fender. The device, while primarily adapted as a boat fender, readily lends itself to various other activities, such as the life preserver, life raft, buoys and various water sports. The fender is extremely light in Weight as compared with fenders heretofore used, since it depends upon the cushioning effect of the inflated air cell instead of the well known cork or kapok stufiings now in use, will not become hard and soggy and will remain pliant and free from noise due to the pounding of a boat thereagainst. The air pressure of the cell [2 is readily ascertainable by engaging a suitable pressure gauge to the valve I4 that normally protrudes outwardly of the folds of the casing for convenient inflation.

It is to be understood, that while a preferred example of the boat fender has been shown and described, it will be apparent that various changes in the shape, size and arrangement of parts may be resorted to as determined by the prior art and the scope of the subjoined claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:
