Description.

through socketsor eyelets-'25 on the'shipy --and'=at'the edgeof the 'bulwarks thereof In service; the rods'23 operate as braces for holding the fenders away from the side 7 hended by cables 2'6. The cabl'esflfi are supported by pulleys Q/i" at the outer-ends f 0f booms 28. The cables' 26' are carriedin- 29 aiid30.

The cabl'es 26 are wrappedon the winches 29 and 30; to entena'bove and below the sameyrespectively; The winc'hes 29 and 30 are disposed in pairs on the shafts 31. Th'fShaft'sSI are eachdrivenby an "elect'rimmotor 32 or other suitable prime mover. By means of the winches 29 and 30 and apparatus connected therewith, the depth at which the tenders 21 are disposed in active service may be regulated, or said fenders may be lifted clear of the water.

The booms 28 are slidably mounted in runways 33 and any suitable means for ex- As seen in the drawings, to embody the tending and retracting the booms 28 may be present invention, a ship 15 has rigidly attached thereto and just forward of the prow employed.

To hold the rear ends of the tenders 21 properly extended, there is provided a two- 2 member spreader rod 34. The spreader rod 34 is jointed at the center by a turnbuckle 35, which may be operated from the stern of the ship, employing therefor any'suitable and convenient means. A flexible shaft with a turning crank may be employed for the purpose of releasing the turnbuckle 35 to permit the rods 34: to part and allow the fenders 21 to assume their inactive position close to and in contact with the side of the ship.

In Figs. 8, 9 and 10, a modified form of the fenders 21 is disclosed. The modification consists in providing av series of separable plates 36. The plates 36 are provided with hinge knuckles 37, which are joined by means of pintle bolts 38. The pintle bolts 38 are permanently secured to the thrust rods 39. The rods 39 when lifted withdraw the pintle pins 38 from the.

knuckles 37, and allow the individual plates 36 to be lifted by the cables 22 to the deck of the ship if desired to be there stowed.

Claims.

1. An apparatus as characterized comprising a plurality of thin metal walls related to said booms for controlling cables guided over the ends'of said booms; means for rotating said winches at will; a plurality of fender bars flexibly connecting said walls and the hull of the ship, said bars being adapted for elevation above the deck of the ship for permitting the approach of said walls tothe sidesof said ship; and spreader rods attached to and extended between the rear ends ofsaid walls for main-.
