Application December 18, 1944, Serial No."568,69l) (o1. 24-265.)

3 Claims.

Our present invention relates to cargo lashing equipment or the like and particularly to the straps of such'equipment.

For safety in transit, it is necessary to lash the cargo in place on the supporting surface of which the decks of cargo ships are good examples. Attempts have been made 'to provide lashing equipment that may be easily used to anchor cargo to the deck. Such equipment consists of rigid straps connected to one another in series, or to anchoring means on the deck, by turnbuckles or other tensioning means by which the lashing equipment may be rendered sufficiently taut.

In accordance with our invention, we provide a strap of simple and rugged construction consisting of a metal blank of desired strength and having, at its ends, sets of loop members. The loop members each consist of an eye establishing portion and arms spaced to receive between them the end portion of the blank and welded to its faces. The loop members are arranged to establish sets of alined eyes spaced to receive between them the eye or eyes of other equipment so that duplicate straps, or straps and other equipment, may be pivotally interconnected in the relation necessary for the lashing of a particular load.

In order that the straps may be readily interchangeable and interconnected, we prefer to arrange the set of loop members at one end of the blank in alinement with the spaces between the loop members of the other set and one side edge of the blank so that one set of loop members of one strap complements one set of loop members of another strap to establish an aperture of substantial length to receive the connecting means.

In accordance with our invention, duplicate and interchangeable straps of great strength well adapted for convenience in use may be economically manufactured. Their great strength results from the fact that, as the loop members are separately formed, they may be of heavier stock than that from which the blank was made and from the fact that their arms permit relatively long lines of weld extending in the direction of strains.

In the accompanying drawing we have shown an illustrative embodiment of our invention from which its novel features and advantages will be readily apparent.

In the drawing:

Fig. 1 shows, in perspective, a strap in accordance with our invention.

Fig. 2 is a plan view showing an interconnected series of our straps.

Fig. 3 is a partly4 sectionedv viewjshowing the locking meinberlin its locked position on the bolt, and u ,i ,i l l Fig. 4 shows, a 'similar view,- thelocking member in its unlocked position. -1 K y v I uasfhingA straps, in accordance with our` invention, consist' of a' metal blankl`v havingv at each end a' setofl loop members generallyindicated at E.

The loop members 6 consist of eye establishing portions 'I and pairs of arms 8 spaced to receive between them the end portions of the blank 5, to the faces of which they are welded as at 9. The eyes 1 of each set of loop members are in alinement and are spaced to receive between them the eye or eyes of such other lashing equipment as turnbuckles, not shown, or other straps as shown in Fig. 2, so that they may be pivotally interconnected as required to complete the lashing.

As it is necessary at times to use a series of straps, we space the loop members 6 of each set relative to each other and to one side edge of the blank 5 so that they aline with spaces between the loop members of the other set and the other side edge of the blank. This construction enables us to use identical straps that may be interchangeably assembled by either reversing their ends or th'eir faces in the assembly. Thus one set of loop members of one strap may always be positioned to complement one set of loop members of another strap to establish an aperture of substantial length to receive the interconnecting device, here shown as a bolt I0.

The bolt I 0 may be locked in any desired way. This may be conveniently effected by forming the bolt I0 with' an annulal` groove II adjacent its unheaded end. As shown in Figs. 3 and 4, the locking member I2 has a keyhole shaped aperture generally indicated at I3. The larger part I4 of the aperture I3 is of suflicient size to receive freely the grooved end of the bolt I0, as sh'own in Fig. 4. The other end I5 of the aperture I3 is shaped to receive tightly the bolt IU in the zone of the groove I I as shown in Fig. 3. For this purpose, the aperture I3 is narrowed as at The resilience of the stock and the narrowing of the aperture at I6 provides a resilient detent which resiliently anchors the member I2 to the bolt I0 when the member I2 is driven into its locked position with a hammer or other con-v venient object thereby to permit our lashing equipment to be quickly and easily assembled and disassembled without the use of special tools.

Lashing straps, in accordance with our invention, are well adapted to meet all requirements. They are inexpensive to manufacture and are easy to assemble, separately or in series, with suitable tensioning means to establish an eilicient cargo lashing. i

What We therefore claim and desire to secure by Letters Patent is:

1. A strap for a cargo lashing device or the like to b e -pivotallyconnected to another. lashing device having van eye,A said strapY comprising a blank, a 'set of loop members on opposite end portions of said blank, each of said loop members including an eye establishing portion and' a pair of arms spaced to receive. an end portion.

of said blank between them and welded. to oppo site surfaces of said blank, the loop members of each set being disposed with their eyes in alinement and spaced to receive between them the eye oi said other lashing device, a, pivot insertable through the eyes of said devices when alined, and a. detachable locking member resiliently anchored to one end of said pivot to lieA at right angles to the plane of the strap and to be moved into and-out of a locked position.

2. The device of claim 1, in which th'e pivot has an annular groove adjacent one of its` ends and the locking; member has a key-hole shape aperture, one portionof which is shaped to receive freely the end of the pivot and another portion of which frictionally receives the pivot in the zone of the groove, and the aperture is narrowed intermediate the portions to establish a resilient detent to permit the locking member to be driven into or out of a locked position,

3. In combination, a pair of members to be pivotally connected to each other, a pin pivotally connecting said members. and.. provided at one end with an annular groove, Vanda detachably locking member resiliently anchored to the .grooved end of said pin and movable through a plane at right angles to the axis of said pin into and. out of 'locked position with respect thereto, said lockingv member comprising a plate having a key-hole shaped aperture, one portion of which is of a size and shape to freely receive said end of the pin and another portion of which is of a size and shape to frictionally receive the pin in the zone of said groove, the aperture being narrowed vintermediate of vsaid portions to establish a resilient detent whereby said locking member may be driven into and out of locked position without completely ldetaching the -same `from th'e pm. v
