. Sept. 28, 1943. H. A. CALAHAN HEAVING LINE DEVICE Filed Jan. 8, 1941 INVENTOR HAROLD AUGUSTI/V CALAHAN ATTORNEYS failure.

Patented Sept. 28, 1943 a YHQEAVINGLINE'DEVICE I I fnitrdldnugasfinG lahad-many. Application January s, isirs nmNaataeiv I (oi.*s 1) i I awe This invention relates to a heaving line; 'i'. e.

a line to be cast or thrown from onepo-intto another as for instance in the case of two vessels separated by an inter'vening stretch of water,

or between a vessel and'adock; It also relates to a device for holding the line in orderly arrangement so"that-'it will not 'foul-orbecome snarledor deranged, and said device also permits'the line to bethrown clear and without friction; regardless of the motion from which it -is thrown. 4

In the callings in which *heavihglines are ordinarily employed, itihas I heretofore been comof the vessel anon practice to use rope or other-cordage which is round or nearly round'in cross-section.- 'Such oorclage is coiled, and the coilis I hove or thrown. A weight, frequently in the form of a Turks ead, is on the end of the line to make the line carry-and to aid in unlayin'g the coils'in the air. v In heaving the coiledline'when it 'is of -sub'-" stantial lengthand weight, it is usually appor tioned into two parts, one part thrown by the right hand and the other'partbythe left "hand.

This method presents twol common' sources of First, the line must always be freshly coiled :just before using .to insure the orderly arrangement of the coils, becauseif a single coil should be out of its proper arrangement, the line will bepulled down in the heave. Second, if in the course of .propulsion,one coil should cross another, the line will be fouled and will fail to reach its objective. Both causesoffailure are inherent-in the fact, that a line that'is round in section must be coiled.

These defects are overcome by in which a narrow flat tape is substituted for. the round-section line. It is not coiled in the usual manner, but is flaked or folded one layer my invention,

upon another, so that a lower layer'cannot be hurled or pulled until the layer above it has been sent on its way. This tape is, flaked into a device which prevents improper flaking, holds the flakes in perfect arrangement so that reflaking immediately prior to use is unnecessary, and permits the tape to be hurled with minimumfriction and without the possibility of fouling. I

Other objects and advantages of my invention will be readily un erstoo from the following description of it taken in connection with the accompanying drawing, in -which Fig. 1 is a top pianview or iny invention with the tape removed.

Fig. 2 is an end elevation thereof, and

Fig. 3 is an enlarged perspective drawing of the trough portion with tape flaked therein and with the center portion isectionedout to re= ducethesize 0f the clrawing.

In all threefigures, similarrparts are indicated by thers'ame reference numerals. r Referring to the drawing! is 'the base in .the form of a slab or plank to be placed on the deck or ground. 2 is a bent'rodpermanently at: 'tachedat both ends to "the base I; and extending upwards therefrom at-an angle with its central portion disposed parallel to the, base. i|; t0

'iorma longitudinalsuport' for the receptacle in :the form of a trough 3, which is pivotally suspended thereon by the flat hooks 4 ate-sufficient distance above the :base I to permit it' to swingfreely. Said trough which may be made of any suitable material such as wood, isqop'en ,atboth ends and is provided. with a hinged cover=5 and asuitablelatch (not-shown) whereby said cover may be locked in a closed position.

Its weight with the tape flaked therein as here- I inafter described and its line of attachment to l the rod 2-are so disposed that the trough 3 will 'be maintained by gravity in a-slanting position relative to the horizontal regardless of the motion of the vesselupon which the base! is placed. 6 is a flat tape of pliable material, which is flaked unfolded back and forth upon itself in orderly arrangement, layer upon layer, in the trough 3., At, theend of 'the tape which lies at the top of the trough is {separably attached a ball "l of suitable weight, brother desired object' adapted to be, thrown or propelled. The

'other end of the tape 6 maybe anchored t ofthe trough or a heavier, stronger line may be at 1 tached to it so that thelight tape may be used as a messenger' t o new a heavier, stronger 1 line between thelpoin'ts bridged'b'y the tape.

A spacing block 'Bisprovided "to fill the space "between the flaked tapeand one side of the trough from. which-it: may readily be removed,

When'said spacing block is in thepos ition shown in Fig. 3, it compels and maintains the orderly I arrangement of the flaked tape. 'When itis removed, preparatory to heavingall friction between the tape and the s'ides'of the trough is reduced to a minimum. The degree of slant of the suspended 'trough 3 is' such'that the s ides of the trough "from bottom'totop will be sub stantially in line with the empower-1 'ofjthe 7 trajectory of the tape when the same/is 'hov'e. e are steps to prevent the trough fro'msliding lengthwise along the rod.

The device is used as follows: First, the trough 3 is removed from the rod 2 and placed upon its bottom with the lid 5 open and the spacing block 8 in place as shown in Fig. 3. The operator next flakes down or arranges in orderly manner, layer upon layer, the tape 6 within the trough 3, the tape being of such a length that unless pressed down, the height of the layers will be somewhat in excess of the inside height of the trough. To maintain the tape in orderly arrangement, the lid is closed and latched over the top of the trough, utilizing the elasticity of the tape to exert pressure thereon. The tape and trough may now be stored with the assurance that the orderly arrangement will be maintained.

When the occasion arises to heave a line, the base I is placed upon the deck or ground as the case may be. The trough is attached to the rod 2 by means of the hooks 4 so that the open top of the trough assumes the position facing the trajectory of the line and maintains that pos'i-' tion despite the movement of the vessel. The lid 5 is now opened to the position shown in Fig. 3, and the spacing block 8 is removed to reduce friction between the tape and the sides of the trough.

For manual heaving, the operator stands behind the device, places his foot on the base I to hold it steady, attaches the ball or weight I to the end of the tape, grasps the tape about four feet from the end, whirls the ball about in a vertical circle, and releases his rasp when the desired line of trajectory is tangential to the circle. Since the tape is arranged layer upon layer, it must leave the trough in proper order and therefore cannot foul either in the trough or in the air.
