Specification of Letters Patent.

Patented Jar g, 1918.

To all whom it may concern."

Be it known that I, Ennnu Coon, a citizen of the United States, and a resident of New York, borough of Brooklyn, in the county of Kings and State of New York. 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 an anchor in which the shank and head are formed as separate parts and subsequently joined together in a secure and permanent manner. By forming the shank and head as separate and distinct parts. each may be formed of material best suited to its particular requirements, and, further, a single type of shank may be employed with a large variety of different shapes and forms of anchor heads. The shape and form of anchor heads vary with the locality in which the anchor is to be used, and according to the ideas of the user.

In attaining the afore-mentioned objects, I have provided an anchor head and shank so formed that the two are ridgidly and permanently joined and secured together, and with the stresses and strains to which the anchor is normally subjected in no wise tending to disrupt or sever the uncture between the two. The employment of a standard type of shank, preferably formed of rolled or forged steel, allows the anchors to be economically manufactured, even though the same vary with regard to their shape and form.

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 invention is disclosed in the accompanying drawings. wherein:

Figure 1 is a view in side elevation of my improved anchor;

F ig. 2 is a bottom plan view thereof;

Fig. 3 is a view in elevation, and partially in section, of the upper extremity of the shank; and

Fig. 4 is a fragmental view in section of the juncture between the anchor shank and head.

Fig. 5 is a view similar to Fig. 4, prior to the welding or joining of the anchor shank to the anchor head by the electrically deposited insert.

Referring specifically to the several views, the shank 10, which, being of regular cross section, may be formed of rolled steel, is provided at its lower extremity with an enlarged wedge-shaped end 11. In accordance with the usual practice, the upper extremity of the shank is provided with an opening 12, for the reception of the removable stock 13, which is held in place by the key 14. An eye 15 is located above the crossbar, and serves as a fastening means for a shackle link, or for the direct securement of a chain or cable thereto.

The head 16 of the anchor which is provided with fiukes 17, which latter may be of any desired shape or configuration, is provided with the enlarged center 18. through which extends the upwardly tapering opening- 19, corresponding to, and receiving therein, the wedge-shaped end 11 of the anchor shank. The wedge-shaped end 11 of theshank. and the side walls of the opening 19 in the head. are provided with registering and inwardly enlarging recesses 20 and 21, the two defining an upwardly enlarging opening 22. Located within the upwardly enlarging opening 22, is an insert 23, preferably formed of metal welded in place by the electric, oxyacetylene or other suitable process, which, having been deposited and welded therein, effects a permanent juncture between the head and shank, and becomes a unitary part thereof.

The welded insert 23, locks the anchor shank and head together, so that they are in effect the same as an anchor composed or formed of a single steel casting or forging. My anchor, however. possesses an additional advantage over the ordinary cast steel anchor, in that while the head may be made of cast steel, the shank may be formed of rolled steel, which latter material is admirably adapted to withstand the strains and stresses to which anchor shanks are normally subjected; also allows the anchor shanks to be economically produced in quantities, and materially reduces the cost and difficulty in producing cast steel anchors.

In order to meet the ideas of fishermen, coast traders of different localities, and mariners in general, it is necessary to provide anchors of many different sizes and different patterns, and this 1 am able to do by standardizing the shank and the opening with which the anchor heads are provided, so that a large variety of anchor heads may be stocked and a relatively few shanks; the particular style or shape of anchor heads and shanks being welded together, in accordance with the demand. Arconsiderable-szwing is thereby efi ected in the amount of finished material necessary to be kept in stock.

What I claim is "1. The method of forming anchors consisting in forming the shank with an enlarged wedge-shaped end, providing a recess in said wedge-shaped end, forming the head of the anchor with an enlarged center with a tapering opening extending therethrough, providing a recess communicating with the tapering opening and registering with the recess of the wedge-shaped end of the shank, and welding an insert within the inwardly enlarging opening defined by the registering recesses of the end of the shank and the anchor head.

2. The method of manufacturing anchors consisting in forming the shank with. a standard size wedge-shape end, forming anchor heads with a standard size tapering opening extending therethrough adapted to receive the wedge-shape end of the anchor shank therein, providing the wedge-shape end of the shank and the walls of the tapering opening of the anchor head with regis tering recesses, fitting an anchor head upon the wedge-shape end of said shank, and welding an insert within the opening defined by the registering recesses of the end of the shank and anchor head.

3. An anchor consisting ofa rolled steel shankand a cast steel head mounted thereon, said head and shank provided with registering recesses, and an insert welded within the opening defined by said registering recesses uniting the anchor head to the shank.

4. An anchor consisting of a shank withan enlarged downwardly and outwardly tapering end, an anchor head provided with an upwardly and inwardly tapering opening extending therethrough, the Wedgeshape end of the shank and the adjacent portion of the anchor head provided with registering recesses therein, said recesses defining an opening tapering in an opposite direction to the-taper of the opening of-the anchor head, and an insert-located within the opening defined by said registering recesses.

5. An anchor comprising a shank with an enlarged wedge-shaped end, a head having a tapering opening extending therethrough receiving the wedge-shaped end of the shank therein, the wedge-shaped end of the shank and the side walls of the tapering opening of the head provided with registering recesses defining an opening at the juncture between the head and shank, and an insert lccated within the said opening, united to the side walls thereof and permanently securing the anchor head to the shank.

Signed at City Island, borough of Bronx, in the county of Bronx and State of New York, this 11th day of January. A. D. 1917.
