NORRIS D. POWELL, OF CHESTER, PENNSYLVANIA, ASSIGNOR, BY lvIESNE ASSI GN MENTS, T BALDI ANCHOR & CHAIN COMPANY, A CORPORATION OF PENNSYL- ANIA.

ANCHOR.

Application filed October 9, 1919, Serial No. 329,516. Renewed December 1, 1922. i

To all whom it may concern.

Be it known that I, Norms D. POWELL,

a citizen of the United States, residing in the city of Chester, county of Delaware, and State of Pennsylvania, have invented a new and useful Anchor, of which the following is a specification.

My invention relates to anchor structure,

particularly of the type in which the shank is rigid with respect to the head or fluke member.

My invention resides in an anchor structure wherein there is cored or otherwise formed a tapering opening in the head or fluke member, which may be of wrought iron or steel, or of cast steel, and a shank, preferably of wrought or forged iron or steel or of cast steel, is so formed or dimensioned that it may be passed lengthwise through said opening in the head or fluke member, the shank being provided at its lower end with a tapering formation conforming substantially with the aforesaid opening in the fluke or head member, but of such size as not to pass therethrough, the lower exposed end of the shank being then secured in place by peening or otherwise;

or the fluke or head member may be compressed upon the tapered end of the shank, which latter may be more or less recessed, whereby an interlock is formed when the head or fluke member is forced into the re cess.

My invention resides in an anchor substantially as hereinafter described.

For an illustration of my structure, reference is to be had to the accompanying drawing, in which:

Fig. l is aside elevational View of the completed shank and head.

Fig. 2 is a fragmentary side elevational view of structure shown in. Fig. 1, partly in section, through the union between shank and head.

Fig. 3 is a fragmentary top plan view of the head or fluke member.

Referring to the drawing, H is the head or fluke member, preferably of cast steel or of wrought or forged iron or steel, integral with which are the fiukes F.

In casting or forging the head member H there is cored or formed therein the preferably elongated opening or hole 71..

The shank S is preferably of wrought or forged iron or steel; or it may be madeof cast steel. It is provided at its upper end with the usual hole 6 through which may extend a stock, not shown. 'A hole f is provided to receive a shackle to which the anchor chain or rope is attached.

The shank is of such dimensions that it may be passed upwardly, Fig. 1, through the hole It in the head member H, until its tapered end 9 contacts with the similarly tapered walls 2' of the hole it in the head member H.

The head member H may be countersunk at j around the edge of the hole It and then the end is of the shank S may be hammered or peened over into the countersunk portion, as indicated in Figs. 1 and 2.

Or the head H may be heated and then shrunk upon the tapered lower end of the shank S.

Additional formation may be given to the lower end of the shank S as indicated in Fig. 2, where the tapered lower end of the shank is shown as slightly recessed or depressed at m and the head member H pressed, hammered, forged or shrunk into the depressions m, m, whereby an interlock is formed between the shank end and the head member H.

By the structure described the tapered end. of the shank fitting in the head member H forms a rigid union withstanding great strains without separation of the. members from each other, since the greater the pull upon the shank S the more firmly are the shank and head held together due to their tapering engagement with each other. p

In addition to the tapering formation described the interlock formed by one ormore of the lateral depressions m in the shank end affords further security.

My preferred combination is cast steelfor the head member H with a forged shank S.

What I claim is:

1. Anchor structure comprising a head having a tapered opening therein, a separate shank having at its lower end a tapered portion fitting in said tapered opening in the head, said shank at its tapered end having a depression into which said head isv fitted to interlock the head and shank. V

2. Anchor structure comprising a head having an opening therein, a separate shank having at its lower end a tapered portion fitting insaid tapered opening in the head,

said shank at its ta ered end havin 0 )0- having an opening therein tapered toward the upper side of the head, a separate shank capable of passing through said opening and having at its lower end a tapered portion fitting in said tapered opening, said shank at its tapered end having a depression into Which said head is fitted, the head at the edge of the lower end of the opening having a countersink, and the lower end or the shank being peened into said countersink.

In testimony whereof I have hereunto aflixed my signature this 8th day of October, 1919.

NORRIS D. POWELL.
