12 Claims.

The present invention relates to marine fenders and it has particular relation to fenders adapted to be positioned along the sides and bow of a ship to cushion or absorb shocks frequently encountered in docking or in passing through restricted channels.

The principal object of the present invention is the provision of a simple and efiicient resilient fender which may quickly and easily be secured to the side or bow of a ship in such man ner as to obtain maximum cushioning efiect and which may readily be replaced when broken or worn.

Other objects will become apparent as the description of the invention proceeds.

In the accompanying drawings:

Fig. l is a view of a ship equipped with fenders constructed in accordance with the present invention;

Fig. 2 is an elevational view of the improved fender;

Fig. 3 is a plan view of the fender shown in Fi 2;

Fig. i is a vertical sectional view taken on line t-- i of Fig. 2;

Fig. 5 is a vertical section showing another manner oi mounting the fender on the side of a ship;

Fig. 6 is a horizontal section taken on line 6-6 of Fig. 5;

Fig. 7 is a vertical section of still another form of securing means;

Fig. 8 is a horizontal section taken on'line 3--8 of Fig. 7

Fig. 9 is a Vertical section showing still another manner of mounting the fender;

Fig. 101s a plan view of the fender mounted on the bow of a ship; and

Fig. 11 is a vertical sectional view taken on line H-H of Fig. 10.

Referring to the drawings and particularly to Figs. 1 to 4 thereof, a ship fender constructed in accordance with the invention, is shown as comprising a plurality of tubular bodies [2 of rubber or rubber reinforced with fabric and having an axial opening I3 and which is mounted upon the sides and bow of a ship. This mounting is obtained by means of a relatively stilt metal rod l4 extending through the opening l3 and secured at its ends in brackets in the form of angle irons i5 bolted to the side or plate 16 of the ship.

The diameter of the rod I4 is considerably less than the internal diameter of the member [2 so that when in position to clamp the member against the side of the ship, it is disposed eccentrically of the member thus providing a space of substantial size outwardly of the rod. This insures a maximum degree of yieldability under the forces of compression. Moreover, the several fenders are, in this manner, maintained against sagging and in alined position so as to provide maximum buffing effect. In addition, the individual members may quickly and easily be replaced when worn or frayed.

If desired, the brackets l5 may be supplemented by additional fastening means such as one or more eye boltsl'l (Figs. 5 to 8) or one or more V-bolts 18 (Fig. 9) which extend through openings 19 in the tubular members 12 and embrace the supporting member. In Figs. 7 and 8 the supporting member is shown as comprising a flexible cable 20 which is threaded through the eye of the bolt H. The advantage of this particular construction is that when the bolt I1 is tightened the eye portion is drawn into the opening I9, thus permitting the member id to flex uniformly throughout its length without being hampered in this respect by the presence of the eye within the space l3.

In Figs. 10 and 11 the improved fender is shown as being mounted upon the bow of the ship. In this case a resilient backing block 2| of rubber or the like is preferably arranged between the fender or fenders and the bow and is formed with recesses 22 within which the members 12 are seat-ed and thus prevented from sagging.

Other modifications and changes in proportions and arrangement of the several necessary elements constituting the invention may be made by those skilled in the art without departing from the nature and scope of the invention as defined in the appended claims.

What we claim is:

1. A marine fender for ships and the like comprising an elongated tubular element of resilient material, a supporting member extending axially through said element, the diameter of said member being substantially less than the internal diameter of said tubular element, and means for securing said supporting member to 4,5 the side of a ship or the like with said supporting member eccentrically disposed with respect to said tubular element and means for clamping the opposite ends of said supporting member firmly against the side of the ship with a substantial air space disposed outwardly from said clamping means, thus insuring adequate yieldability when subjected to compressive forces.

2. A marine fender for ships and the like com prising an elongated tubular element of resilient material, a substantially rigid supporting member extending axially through said element, the diameter of said member being substantially less than the internal diameter of said tubular element, and bracket means for securing said supporting member to the side of a ship or the like with said supporting member eccentrically disposed toward the ship with respect to said tubular element and clamping the supporting member firmly against the side of the ship with a substantial air space disposed outwardly therefrom, thus insuring adequate yieldability when subjected to compressive forces.

3. A marine fender for ships and the like comprising an elongated tubular element of resilient material, a supporting member extending axially through said element, the diameter of said member being substantially less than the internal diameter of said tubular element, means for securing said supporting member to the side of a ship or the like with said supporting member eccentrically disposed with respect to said tubular element and means for clamping the opposite ends of said supporting member firmly against the side of the ship with a substantial air space disposed outwardly therefrom, thus insuring adequate yieldability when subjected to compressive forces, and means extending laterally through said tubular element and engaging said supporting member for additionally clamping said tubular element to the side of the ship.

4. A marine fender for ships and the like comprising an elongated tubular element of resilient material, a rod extending axially through said element and being sufiiciently still to withstand material bending under localized bending stresses, the diameter of said rod being substantially less than the internal diameter of said tubular element, bracket means for securing said rod to the side of a ship or the like with said rod eccentrically disposed with respect to said tubular element and clamping the same firmly against the side of the ship with a substantial air space disposed outwardly therefrom, thus insuring adequate yieldability when subjected to compressive forces, and screw eye means extending laterally through said tubular element and embracing said rod for additionally clamping said tubular element to the side of the ship.

5. A marine fender for ships and the like comprising an elongated tubular element of resilient material, a flexible cable extending axially through said element, the diameter of said cable being substantially less than the internal diameter of said tubular element, means for securing said cable to the side of a ship or the like with said cable eccentrically disposed with respect to said tubular element and clamping the same firmly against the side of the ship with a substantial air space disposed outwardly therefrom, thus insuring adequate yieldability when subjected to compressive forces, and screw eye means extending laterally through an opening in said tubular member and embracing said cable for additionally clamping said tubular member to the side of the ship, the eye portion of said screw eye meansbeing located within the opening in said tubular member when in clamping position.

6.
