im Il l Patented Apr. 5, 1932 Unire STA-TES PATENT MICHEL HILL, or; san4 riannorsco, oALrroitirLaV SHIPS FENDER .Application filed-December `20, 1930.` Serial No. 503,748.

This invention pertains to ships fenders and .more particularly -to improvements in fenders that servethe purpose of absorbingy terioration of any one section it maybe re-l moved and replaced at considerably less than the cost of an entire new fender.

The object of the invention is accomplished through the provision of a fender d a lining adapted to fit against the surface-to be protected, a cushion section formed of,

numerous bundles of resilient material, and a wearing section of rugged construction se- 4g cured with rela-tion to the lining and adapted to support the cushion section thereagainst.

Fenders manufactured in accordancewith my invention may be applied to any part of aship where a'fender is necessary, or o may be suitably used "on wharves and piers and, in fact, theyare notl limited to marine ywill be found capable of applicause, but

where it is desirable tion in many instances o ing together.

One form of my invention is shown by way of illustration inV the accompanyingdrawings and described.- i n greater detail in the following specication.

Fig. 5 is a perspective view showing a' which is composed of three sections, namely,l

to cushion the shock of large Aobjects strik-l collapsible link employed in thebinding of.v the cushion element.

Fig. 6 is a modiiication of the same. Referring more particularly tothe drawings, in Figs. land 2 I'sho-w a portion of a ships bow 1() having a fender attached thereto. The fender is composed of a lining' 11Y conforming to and contacting withl the bow l of the ship, a cushion section indicated at 12 positioned next thereto, and a wearing section 13. The lining section 11 and the wearing section 13 areV composed of fiat pieces of durablel resilient material, the shapes of-l which` may be best seenv inFig; `3. y

yThe material of which these sections are formed is preferably rubber, such as may be salvaged from old automobile tires, rubber hose, belting or other articles that have outworn their useful life. rIhe stripsV are cut to any desired size and may be graduatedjin size to form tapered ends on thefender, as shown in '.Fig. 1, if desired. The strips arer held together-by means of tie rods 14 which pass through .holes formed in the strips .at intervals, as shown. The tie rods maybe in the forni of steel rods or may,` if desired, be composed of Vchain or cable. The tie rods 14 of the liningsection are secured at 'their termini to .steelv plates 15 in any suitable' manner and thetie rods of the vwearing section are similarly secu-red to steel 'plates 16, as shown inFig. 1. The steel' `plates 16 may be provided `with a bracket 17 tol whichv aV turn buckle-18 is attached, and by means ofwhich the fender may be firmly secured to a ring bolt 19 providedv in the side of theA ship.

Suitable-links 20, as best shownv inv Fig. 3, are carried by the-uppermost and l-owermostrods 14 in each of .the sectioiis-ll'and-l?) and spaced thereon at suitable intervals. The links 20 are secured 'together at 'their ends by means of bolts .21, so that tightening Y of these boltsv will cause the links to Abe drawn toward each other, thus causing the outer or wearing section 13 to bedrawn inl. wardly toward thellining section,with the result that the cushion section 12 will'be slightly compressed and firmlyA held therebetween. Suitable links 22 may also be provided for! engagement with the uppermost tie rods 14 25 of waste rubber.

tion `of it be used to make the large strips to aHord means to attach a rope or cable 23 depending from the bow stem of the ship to support the forward end of the fender. A steel stem plate 24 may be interposed, when necessary, between the fender and the ship toreduce wear caused by friction.

. The cushion element referred to above is formed of a plurality of elon ated bundles The ru ber used in these cushions maybe in pieces of any size or shape, as the cushions are bound by means of rope, wire, metal bands or clips, not

shown. The cushions may be maintained in the form ofl a resilient unit by means of metal strips 26 placed at intervals on two sides of them and interconnected by means of collapsible links 27, as sho-wn in Fig. e. The links 27 are horizontally disposedand may also be employed at intervals throughout theV lengths of the strips 26. As the cushion is subjected to shock, it will be seen that the links :27 will be collapsed as shown inFig. 5.V I

A modification of this structure may be seen in Fig. 6, in which the ends of bands 28 are cut so as to interlock one with the other., and yet permit freedom ofmovement toward each other. been found desirable, it'will be understood that the-cushion members need not necessarily be bound together by such means, but may be wholly supported by the lining and wearing sections and the links 20V and the bolts 2l, as shown in Figs. l and 3. j

` In applying the fender to a ship, the lining sectionrwo'uld first be suspended in' position against the bow of the ship. The wearing section 13 would then be supported in front ofthe lining section and the bolts 2l connecting the lower ends of the sections together would be loosely inserted. The cushion elements 25' would then be placed in position between the lining and wearing sections, after whichv'the bolts 2l connecting the upper ends ofthe sections could be inserted. At this Vtime 'all ofthe bolts 21 would be tightened until'the fender was given suitable compactness 'and rigidity. It is also possible to completely assemble the fender and then suspend it from the ship in a single unit. Repairs and replacements may, of course, be made in either mannen It will be seen from the foregoing that I- have provided al fender which is composed of three individual sections, each serving a separate rpurpose and readily removable for repairs or renewal. The fender is chiefly composed of waste material, as has been described, and the use of the material is particularly economical, as not only will the major porforming the rwearing and lining sections, but

the scraps may be bound into the bundles 25 of the cushion sections. As rubber tires, belts, hose, and the like are interwoven with vVhile the above structure has fibrous material, it will be seen that the wearing and lining sections will have the ends of this material exposed, thus providing a surface that is exceptionally rugged and durable. It will also be noticed that the holes through which the tie rods 14 pass in the wearing section are formed as near as is practical to the inner edge of the strips forming this section, thus presenting asv large an area as possible for wear before it will be necessary to replace this section. y

vWhile I have shown the preferred form of my invention, itl should be understood that various changes may be resorted to in the arrangement and construction of its several parts within the spirit and scope ofthe appended claims. y

Having thus described my invention, what I claim and desire tosecure by Letters Patent is- Y A, Y
