l ITE S AT PAN SHIP-FENDER.

Specification of Letters Patent.

Patented Feb. 4, 1919.

Application filed July 2 1918. Serial No. 243,049.

To all whom it may concern:

Be it known that I, ANDREJ ZABAWA, a subject of the Emperor of Austria, residing at Shawenegan Falls, Province of Quebec, and Dominion of Canada, have invented certain new and useful Improvements in Ship-Fenders, of which the following is a specification.

This invention relates to improvements in ship fenders, and has as its special ob ect the provision of a plurality of fender-plates which may be extended or retracted with respect to the hull of a ship in an expeditious manner.

A further object is to provide a novel form of supporting means for the fender plates, whereby the plates can be extended at an angle, as well as raised and lowered, provision being made for rigidly clamping the parts after adjustment.

A still further object is to provide supports containing resilient elements, so that the shock or impact received by the plate is partially absorbed and cushioned before it reaches the hull of the ship. 7

These and other like objects are attained by the novel construction and combination of parts hereinafter described and shown in the accompanying drawings, forming a material part of this disclosure, and in which Figure 1 is a side elevational view showing a conventional type of ship, and indicating the application of fending elements.

Fig. 2 is an enlarged transverse sectional view of the ship and an end elevational view of the plates and their attaching means.

Fig. 3 is a rear plan view of one of the fending plates.

Fig. 4 is an end elevational View thereof, and

Fig. 5 is a fragmentary top plan view of the same.

Engaged with the hull of the ship 10, adjacent to the normal water line thereof, are a plurality of uniformly spaced brackets 14, similar brackets 15 being in register directly above, and hingedly engaged in the brackets 15, are arms 17, containing a plurality of perforated openings 18, the arms being bent at right angles as indicated at 19, the extending ends 20, continuing outward, in a plane parallel with the main portions 17 e extremities of the elements 20 are rounded and engaged by pins 21 with brackets- 22 rigidly secured to the inner upper Sides of defending armor plates 25, the same being formed with beveled edges 26 as indicated.

Secured in register upon the plates 25, with the brackets 22, are arcuate plates 27, fastened by the inturned flanges 28, and formed with a plurality of perforations 29, registerablewith an opening formed in the element 20, so as to receive a pin 30, which may be entered into any of the several perforations 29, thereby holding the plate 25 a; various angles with relation to the arms 1 20.

Pivoted in the brackets 14: are other arms 33, having outer forked ends 34, engageable by the pins 35, with any of the several perforations 18 formed in the arms or bars 17 thereby affording means whereby the arms may be raised or lowered and adjustably held at different angles relative to the hull of the ship, and it will be obvious that as the armor plates 25 are supported by the arms, they are correspondingly raised and lowered, and due to the perforated sector plates 27, the armor plates may be set at an angle in a manner which will be clearly understood.

Affixed in the upper edges of the plate 25 are eyes 38, engaging with cables 40, extend ing upward alongside the hull of the ship, and passing over drums or rollers 41, secured upon the shaft 42, arranged longitudinally of the ship in supporting brackets 43, the shaft having at one end a crank 44 by means of which it may be rotated, thus raising or lowering all of the several fending plates, simultaneously, and it will be obvious that power can be applied to the shaft 42 if it be desired.

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

1. In a ship fender, the combination with a plurality of rectangular armor plates, brackets up on the inner sides thereof, other brackets secured upon the hull of the ship, connecting levers pivotally engaged at their ends in their respective brackets, said connecting levers having a plurality of spaced perforations, support arms engaged with the hull of the ship at one end, said support arms being forked, means for engaging said forked arms with any of the mentioned perforations in said support levers, sectors engaged contiguous to the brackets on said varmor plates, said sectors having perforaa plurality of armor plates havingbrackets upon the inner side thereof, lever arms having a right-angularly bent portion therein pivotally engaged in said brackets said lever arms having a plurality of perforations, support brackets extending from the hull of the ship pivotally engaging the inner end of said support levers, forked arms engage able with any of the perforations in said levers, brackets in which said forked arms are pivotally engaged sectors secured to the inher side of said armor plates adjacent to said brackets, said sectors having a plurality of perforations, pins passing through said support levers engageable in any of the perforations of said sectors whereby said plates may be held rigidly extended at an injected angle with respect to said support levers, eyes secured at the upper edges of said plates, cables passing through said eyes shafts mounted longitudinally on the deck of the ship, drums fixed upon said shaft over which said cables run and means for actuating said shafts whereby said armor plates may be raised orlowered.

In testimony whereof I have affixed my signature.

ANDREJ ZARA-WA.
