Specification of Letters Patent.

Patented Aug. 15, 1916.

Application filed March 25,1916. Serial No. 86,552.

T 0 all whom it may concern:

Be it known that I, WVILLIAM D. SARGENT, a citizen of the United States, and a resident of WVest Orange, in the county of Essex and State of New Jersey, have made and invented certain new and useful Improvements in Anchors, of which the following is a specification.

My invention relates to anchors, and particularly to that type wherein the shank is loosely connected to the head.

The object of the present invention is to provide an anchor having large bearing and supporting areas between the shank and head, so that the anchor is capable of rendering satisfactory service for a considerable period of time; and, further, to provide improved means for locking the shank against disengagement from the head, the improved means partaking of the nature of a broad flat key, and downwardly enlarging recesses which is provided for its reception.

Other objects and advantages will appear as the description proceeds, wherein it is to be understood that changes in the precise embodiment of the invention can be'made within the scope of what is claimed without departing from the spirit thereof.

The preferred embodiment of my inven tion is disclosed in the accompanying drawings, wherein Figure 1 is a view in front elevation of an anchor embodying the characteristic features of my invention; Fig. 2 is a view in vertical section taken on the line 2-2 of Fig. 1; Fig. 3 is a view in vertical section taken on the line 38 of Fig. 2; and Fig. 4 is a fragmental view in section diagrammatically illustrating the manner in which the key is moved into its seated position.

Referring specifically to the several views, the head 5 is provided with the usual type of flukes 6, and with the shank-receiving slot 7. The shank 8 is provided at its upper extremity with the lugs or supporting ledges 9, which are of elliptical form, and are adapted to bear and rest upon the bottom walls 10 of the-lug-receiving orifice 11 with which the head of the anchor is provided, and which orifice communicates with the shank-receiving slot 7. The side walls 12 of the slot 7 are inclined, allowing the shank to swing to either side, as indicated by the dotted lines in Fig. 3. The bottom walls 10 of the lug orifice are also of an elliptical form, and provide for a large area of contact between the supporting ledges of the shank and the anchor head.

The shank 8 is assembled upon the head by passing the lower extremity thereof down through the orifice 11 and slot 7, and in order to prevent the shank from becoming disengaged from the anchor head, the locking key 13 is provided, and is substantially rectangular in cross-section, the broad flat side being positioned so as to face the elliptical lugs 9 upon the upper extremity of the shank. The side walls 14 of the orifice 11 are provided with the recesses 15, these recesses widening at their lower extremities to form the pockets 16. As disclosed in Fig. 2, the depth A of the recesses 15 is uniform throughout, so that the key 13 may be lowered into the pockets 16 in an unbent condition. In securing the key in place, it is turned upon its edge as illustrated in Fig. 4, and so lowered. As the key enters the pockets 16, it is tilted as indicated by the dotted lines 17, in Fig. l, and then overturned to occupy the position with the fiat side resting upon the bottom wall 18 of the said recesses. The key is then welded in position, and as so located, exposes a broad fiat face against which the sup porting lugs of the shank may contact or hammer without injury.

That I claim is 1. An anchor comprising a head with communicating shank-receiving slot and lug-receiving orifice, a shank with supporting lugs, said lugs positioned within said lug-receiving orifice, the side walls of said orifice provided with downwardly enlarging recesses of substantially uniform depth throughout, and a substantially rectangular key located within said recesses, with the broad fiat side thereof adjacent the lugs of said shank.

2. An anchor comprising a head with communicating shank-receiving slot and lugreceiving orifice, a shank with supporting lugs, said lugs positioned within said lugreceiving orifice, the side walls of said orifice provided with downwardly enlarging recesses of substantially uniform depth throughout, and a substantially rectangular key located within said recesses, with the broad flat side thereof adjacent the lugs of said shank, said lugs and the bottom walls of said lug-receiving orifice of substantially elliptical contour.

anchor comprising a head with communicating shank-receiving slot and lugreceiving orifices, a shank with supporting lugs, said lugs positioned within said lug-receiving orifice, the side walls of said orifice provided with downwardly enlarging recesses of substantially uniform depth throughout, and a substantially rectangular key located within said recesses, with the broad flat side thereof adjacent the lugs of said shank, said key rigidly secured to the 10 walls of said recesses.

Signed at Bayonne, in the county of Hudson and State of New Jersey, this 23rd day of March, A. D. 1916.

WILLIAM D. SARGENT.
