for cargoes, having improved means adapted tosubstantially straddle the flange of a flanged beam or similar member of a ships structure, and place the stress of a lashed cargo nearer the web of said beam, whereby any tendency of distortion of said flange may be reduced.

Another object is to provide a new and improved device of the character set forth having improved means for easily and rigidly, yet detachably, securing an end of a cargo lashing to a ships beam or similar structure, whereby relative movement of a cargo during a turbulent passage or transportation may be eliminated.

A still further object is to provide a new and improved anchor of the type described having improved means adapted to permit easy and secure attachment to a structure, and also adapted to permit and facilitate removal therefrom without damage to said structure.

It also is an object to provide a new and improved lashing anchor having a greatly simplified and economically produced structure having a substantial durability to permit repeated usage and also having a maximum efficiency and ease of operation.

The invention comprises theimproved device disclosed in the drawings forming a part of the present application, and in which- Figure 1 is a partly broken plan view of a cargo lashed to a ships structure mainly by the improved lashing anchor;

Figure 2 is an enlarged elevation, partly broken, disclosing the manner in which the anchor substantially straddles the flange of a beam and locked in a position which places the stress of a load upon the web of said beam;

Figure 3 is a broken elevation of the right hand end of Figure 2; and

Figure 4 is a transverse sectional view taken on line 4-4 of Figure 2, in the direction indicated.

Referring to the drawings:

a claims; (01. 105 369) The numeral I is used to designate in general an anchor comprising a hook having a bay 2- adapted to straddle or enclose the flange 3 of an angle or other flanged structural beam having a Web 4. The end of the shank 6 of the hook or anchor I is provided with a lug 1 arranged directly opposite the bay 2 of said hook or anchor I and is adapted to engage the back of the beam or web 4 in a region coplanar with the flange 3 and thereby prevent removal of the bay 2 from said flange 3, when the point of said hook is elevated to bring the inner side of the shank 6 snugly into coplanar contact with the outer face of said flange 3 by the insertion of a suitable wedge 8 between said hook end and the upper surface of said flange 3, said wedge i8 being arranged virtually to engage the cove or inner corner 9 between the upper surface of the flange 3 and web 4, whereby the stress or strain of a load is placed closer to said web 4 whereby tendency of distortion of said flange 3 is reduced.

The outer sideof the shank 6 is provided with a preferably integrally formed loop I2, which may be positioned longitudinally or transversely of said shank 6, according to the requirements or position of a cargo to be lashed. The loop I2 is adapted to be engaged by one end of a lashing I4, generally of the flat steel strap type, passed around a cargo I6 with its other end secured to a second anchor and tightened to secure said cargo against movement by conventional lashing tighteners of any suitable type, as indicated at I8 in Figure 1 of the drawings.

In operation:

A lower anchor I is first placed with its bay 2 astride the flange 3, and a wedge 8 is driven be tween the point of the hook thereof and the upper surface of the flange 3 until the lug I is moved into engaging relation with the back of the web 4 and in a region coplanar with the said flange, with the lashing I 4 extended laterally from said flange. A cargo I6 to be lashed is then placed upon the extended lashing I4, and the latter then is formed around said cargo and its free end threaded through the loop I2 of a similar upper anchor I, on the flange 3, and, by means of a conventional tightener I8, said lashing I4 is tightened to securely hold said cargo I6 snugly against the outer surface of the flange 3, which will transmit the tension or load of said lashing and cargo directly onto the wedges 8 in closer proximity to the web 4 and thereby reduce any tendency of said load or tension to distort said flange 3.

' The lashings I4 and anchors I easily and quickly may be removed to release a cargo 16, to be used repeatedly for successive cargoes, by the simple expedient of reversing the tighteners l8 to relieve tension of the lashings l4, after which the wedges 8 are driven out which will permit the lugs I to be removed from the rear sides of the webs 4, after which the anchors l easily and quickly may be backed oil from the flanges 3 and removed.

Having described my invention, I claim:

1. A lashing anchor comprising a hook having a bay adapted to straddle a free edge of a flange on a structural beam and having a lug thereon opposite said hook adapted to engage the back of said beam in a region coplanar with said flange and hold said hook astride' said flange; a wedge adapted to engage said beam between said flange and the point of said hook and hold the same astride said flange; and a loop on the shank of said hook adapted to be engaged by a strap lashing.

2. A lashing anchor comprising a hook adapted to straddle a free edge of a flange of a struc tural beam, and having a lug adapted to engage the back of said beam in a region coplanar with said flange and hold said anchor astride said flange, and also having a loop formed on said anchor; and a wedge adapted to support the point of said hook on said beam between the flange and web thereof and said lug in engaging relation with the said back of said beam.

MANLY S. HARRIS.
