Application filed December MB, rear. serial life. GQQALW.

' My invention relates to supplying ships with oiland it has particular reference to the fueling of ships while travelling at considerable speed at sea, I Other and further objects of the invention will be apparent hereinafter and the novelty of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the acco mpan'ying'drawings in which Figures 1 and 2 are respectively a plan and elevation of the stern of a fueling ship connected to the bow of a ship to be fueled with the necessary lines in place; Fig. 3 is a'view of the stern portion of the fueling ship on a larger scale than that of Figs. 1 and 2; Fig. 4 is an elevational view of the stern portion of the fueling ship showing modified means for handling the various lines; Fig. 5 is an elevation of a hose jack 2a or a support for the fuel hose; Fig. 6 IS a vertical section taken on line 6-6 of Fig. 5; Fig. 7 is a vertical section on the line 77 of Figure 5; Fig. 8 is a side elevation of the hook portion of a hanger designed to support 2 the hose; F ig, 9 is a rear View of the device shown in Fig. 8; Fig. 10 is a perspective view of the hanger shown in Figs. 8 and 9 with an oil hose in place; Fig. 11 is a plan view of a modified form of hose support; Fig. 12 is a he view in elevation of the hose support shown in Fig. 11; Fig. 13 is a view, partly in section, looking from the left of 12 showing a portion of the saddle or support proper cut away; Fig. It is a view in perspective showing the means for securing together at the hose couplings of the jackstay sections. of

. securing the latter to the fuelhose, and Fig. 15 is a plan view of the arrangement shown in Fig. 14.

Referring to Figs. 1, 2 and 3, it will be seen that l have provided two elevated hawsers 2 and 3'co1inecting the rear portion of the fuel ship A with the bow of the ship lfi to be fueled. From each of the hawsers 2 and 3 l suspend a hose for conducting the liquid fuel. A fixed line 1 known as a distance hawser usually very slack limits the distance between the ships although is not intended to act at a tow line. The

hawsers

2 and 3 are attached to the fuel ship in a manier to permit the towing of the ship to be fueled as will be fully explained hereinafter. Tn Figs: 1 and .2 T have illustrated two hose and twosupporting hawsers and in Fig. 4 an arrangement wherein but one hose is used but it will be understood that the number of all hit

hose and hawsers used may be varied as desired, similar apparatus being used in connection with each hose and its supporting hawser.

The method of fueling by the apparatus illustrated in Figs. 1, 2 and 3 is carried out in the followingmanner:

(l) lBoth ships maneuveruntil the one to be fueled follows astern and in line with the fuel ship at the same speed at a suitable distance, for example about 450 feet or less. 7

(2) The fuel ship lowers a float to which are attached three manila lines, which are picked up by the ship to be fueled. By means of these three lines, three hawsers are pulled over to the ship to be fueled. .These lines comprise a hawser 1, to be referred to as a distance hawser, the function of which will be hereinafter described, and two towing and supporting

hawsers

2 and 3 from each of which a fuel hose is to be suspended. At the time the supporting hawsers2and3are pulled over, two messenger lines may conveniently be brought over. The function of these is to pull over the fuel hose suspended from the hawsers in the manner to he described. The manner of conveying the lines above mentioned to the ship B forms no part of the present invention and the above procedure is given as one of a variety of ways in which this may be accomplished.

The function of the distance hawser is to prevent the ships from exceeding a predetermineddistance between-them of, say 300 or 400 feet. The distance hawser is maintained slack, sagging considerably into the sea, and is not used for towing. The distance hawser has an additional function in that it tends automatically to maintain a uniform distance between the ships for the reason that whenever there is a tendency for the towed ship to lose speed, the distance hawser will tighten, the sag will decrease and its tension will increase. This increased hawser tension effects a partial slowing-down of the fuel ship and a gradual speeding-up of the towed ship and whenever the ships approach one another the distance hawser slackens, reduces its pull and the towed ship automatically settles hack to normal distance.

(3) The tension of the supporting hawsers is regulated by means of automatic tensioning engines 10 on the fueling ship and to which the hawsers are attached. ft is desirable that an approximately uniform tension be maintained in the supporting hawsers by tartan fit) till

hit

lltlti lllO means of which the ship to be fueled is also towed. E prefer to use for this purpose automatie tension engines of the type invented by me and disclosed in my Patent No. 1,405,612 and the patents and applications therein referred to. The supporting

hawsers

2 and 3 having each been put under tension. by the automatic tension.

engines

10, 10, the fuel ship may increase her speed up to, say, nine or ten knots. During this period the ship to be fueled must regulate her revolutions so that the distance hawser will remain very slack.

I provide

blocks

20, 20, through which the hawsers 2 and 8 pass respectively and to each of which is connected aline 25, operated by Winch 890. Thus, by means of

Winches

390, 390,1 may haul hawsers 2 and 8 down close to the deck, whereby each hose 30 may be ata cached, in a manner to be described.

(4) The speed oi? both ships having been regulated as indicated in the -fioregoing, the supporting havvsers 2 and 3v are hauled down close to the deck by operating"

winches

390, 390, in the manner described, so that they Wili be easily accessibie to the men for hooking on the hose. This hauling down does not materially increase the. tension in the

hawscrs

2 and 3, the tension engines 10 pay out the requisite amounts of the hawsers.

(5) The oil hose 30 are new hooked on to their supporting hawsers by attaching the supporting hangers 31, spaced. say, every five feet, The problem of supporting" a long tie);- ible conduit, such as an oil hose, is rather comlex. The tensile strength of the hose is not suihcient to bear the -force necessary to sup port the hose when ioeded. Furthermore, it is advisable to place considerable tension on the hose otherwise it will sag between transverse supports to such an extent that oil will not readily flow therethrough. Furthermore, if all the tension is applied at the ends, the Weight of the hose when loaded would be sui iicient to break it,

ha e devised me"- for supporting the hose which consists in attaching a cahle to the hose regular intervals and making the length of cable between points of attachment slightly shorter thgn corresponding sections of the se, so that a predetermined tension appl to the hose, The tension on the hose is ii 'ted by the cabie so that there is no danger oi severing the hose due abnormai. pull, when the ships pitch. By this means the tension in 1 out its ieagt nose can be distributed throughc h and limited to apredetermined amount.

A 32 of a cahle oi ackstay 'is at tar-hell s l" in of mm t each ho,

A shackle 133 is p asscd through one thiinble 132 and. is secured to the end of the adjacent jac stay section by means of a pin 134; passing through shackle 133 and thimbie 132 of that iaclrstay section, as is. clearly shown in Fig. 15. The jaclrstay sections 32 may then be securely lashed to the hose'30 by means of lashing 135 which passed over and under shackle 133 and around the hose coupling 136, as shrmn. 'l. he hose 30 may be supported at coupling; by a strap 38, in which case, additional lashing of jackstay sections to the hose will be socured. It will be noted that when the hanger 31 is attached. to the hose by 1110.11" 5 oi the manila strap 33, as shown in detail in Figone 10, the strap 33 passes around both the oil hose and the jaciistay section u'hei by e the latter lily bound to the hose.

so that by rotation of the latter, any desired tension may be placed in the jackstay... By appropriate clutch mechanism, a winch 390 be used to operate both the jackpennant 36, and the block 20, by means of the lines 25. When the winch 390, provides the requisite tension in the ja clrstays 35, a clamp 47, engages the supporting hawser 2 for example, operated by toggle linlrs a9 and 72 attached to the plates 70 by means of pin 71. The clamp l7 may conveniently have an arcuate bearing surface l8. By this means it am able to keep the jiaclrs'tay 35 under the desired tension and yet allow for slipping in case jackstay 35 should be set up. to the upright lit) by means of a swivel connection ll to avoid twistingstresses in the iaclrpennant 33. Th case the clamp slips a winchman may talre a manila line attached to the jaclrstay 35 and aid of the winchBllti or capstan i not shown) until the jacltstay is again under the desired tension.

The haul-down bloclrs E20, are paid out to permit the hose to be clear of the water when all connections are made, and the pump ing operations maythen begin. litter the i'ueling operations are finished, the oil is blown from the hose, the latter is detached from the ship receiving the iiuel; the main cable is hauled down by means oil winch 390 to a position conveniently close to the declr and the hose manually hauled baclr to the ihuel ship. During the fueling operation, the ships may proceed underway at a speed oi even twelve lrnots. lWhen fueling is completed the shi s may be slowed down. When the hose has lieen hauled in, the supporting

hawsers

2 and 3 are wound in by means of the automatic machines 10.

its an alternative to the arrangement above described for maintaining tension in the iaclrstay 35, ll may provide the arrangement shown in Fig. 4i, in which the jackstay pennant 36 is connected to an automatic ten sion engine 10 similar to automatic tension engine 10 operating the hawser By this arrangement ll rely upon the automatic tension engine 10" to maintain a desired tension in the jaclrstay instead of the winch 390 and the clamp ll. This arrangement has the advantage that the constant tension is at all times maintained in jackstay 35 and it may, therefore, dispense with clamp d7 Figs. 11, it and 13 showing the support d2 without the clamp. Tn this modification it provide a haul-down block 20 connected. by tackle 21' to the deck through block Q2 attached thereto. The block-20" and tackle 2i are operated by winch 23. The dotted lines indi eats the position oil the lines preparatory to attaching and detaching the hose.

Thejaclrpennant 36 is attached,

pull upon it with the li will now describe in detail certain parts oi the apparatus which are necessary or ad'- vantageous tor the carrying out of my invention.

The hangers 31 are exemplified in Figure 10 in which 33 denotes an endless manila strap adapted to grip the hose 30, and jackstay 35. The strap 33 is secured to the end portion oi the hoolr 52 by being looped around the shanlr portion 51, both ends pass ing through the eye 53. in order to securely loch the hook to the hawser 2, the hook is pro,- vided with a tongue lil pivotally secured to the head 55 by means of pin 56 and cotter 57. The end of the tongue 60 passes through a slot 61 and is held firmly against the edge 62 oil the opposite face of the book by means of spring 63, the latter being secured to the head of the hook by means of bolt (it. it will be seen that owing to the position of the pivot 56 with reierence to the end portion 60 ot the tongue, the resultant of any force Jill exerted on the portion til by a movement of no tendency tor the end portion (30 ot the tongue to move out of engagement with the contacting surface 62 against which it is firmly pressed by spring 33.

' litwill be noted that by means of mast 38 on the fuel ship, it am able to support the fuel hose 30 clear oi" the water, while providing an arrangement whereby the hose may be lowcred when it is desirable to do so. By suspending the hose clear of the water, it achieve a notable advantage, in that the oil. passing through the hose is not chilled by the cooler sea water, its viscosity increased and tlow diminished. Furthermore, ll thereby eliminate the drag caused by the sagging of the hose in the sea, which may amount to several thousand pounds additional stress in the towing hawsers.

it will be seeh that l have provided a simple and efiective means tor supplying fuel to i a ship while in motion, and while it have shown apparatus embodying my invention, it will be understood that the same is illustrative only and that the details thereot as well as the procedure may be variedv considerably without departing from the spirit of my invention.
