Specification of Letters Patent.

Patented Dec. 9, 1919.

Application filed April 22, 1919. Serial No. 292,004.

To all whom it may concern:

Be it known that I, THOMAS P. Fos'rnn, a subject of the King; of Great Britain, residing at Seal Cove, Province of New Brunswick, Canada, have invented certain new and useful Improvements in Anchors; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to anchors, and an object of the present invention is to provide a device of this character with an auxiliary coupling connection whereby V a substantially direct pull may be gainer whereby should the flukes of the anchor be fouled by rocks or other obstructions it can be easily and readily released, thereby preventing the anchor from becoming lost when being used.

With the above and other objects in view which will hereinafter appear as the de scription continues, the invention consists of the novel features of construction, combination and formation of parts as will be here inafter more fully described and particularly pointed out in the appended claim.

In the accompanying drawings has been shown a simple and preferred form. of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details herein exhibited, but the right is hereby reserved to any changes, alterations or modifications to which recourse may be had that come within the scope of the claim without departing from the spirit of the invention or sacrificing the efficiency of the same.

In the accompanying drawings:

Figure 1 is a side elevation of the anchor embodying the present invention;

Fig. 2 is an end elevation of the same; F 1g. 3 is a detail horizontal section taken on the line 33 of Fig. 1; and,

Fig. 4 is an enlarged detail section taken on the line 4% of Fig. 3.

Referring now more particularly to the accompanying drawings wherein ike' and corresponding parts are designated by simiin its upper end the usual stock 4. The

shank 3 may be made somewhat lighter than the shanks used 011 ordinary anchors, due to the fact that the cable is not connected directly to the shank, and this shank may be made so as to only have sufficient strength for righting the anchor. The anchor as so far described is substantially the same as ordinary anchors and may be of any desired size. Formed with the upper face of the crown 1 are the ears 5, extending through each pair of ears 5 is a bolt 6 and these bolts 6 are retained in position by the cotter pins or like fastening members 7. In the present anchor a second shank 8 is employed which is formed of a U-shaped bar having enlarged square lower ends 9 which are socured within the ears 5 by means of the bolts 6. This auxiliary shank 8 extends over and down along the opposite sides of the shank 3. Connected to this shank 8 is a ring 10 and the usual cable is secured to this ring.

hen the anchor is dropped from a ship upon the river bottom the flukes are likely to become fouled by roots, rocks or other obstructions in the river bottom, and if the cable was connected directly to the shank 8 it would be almost impossible to withdraw the anchor and in most cases the anchors are lost. By providing the auxiliary shank S and having the ring 10 loosely mounted thereupon it is apparent that should any one of the flukes be fouled by obstructions in the river bottom that the ring 10 would travel upon the auxiliary shank 8 until it has assumed a position whereby a substantially direct pull might be gained upon the anchor so as to withdraw the same from its fouled obstruction. When the anchor flakes are released from the obstructions the anchor may again fall to one side and it will again take hold upon the crown when the strain is exerted. upon the cable. due to the fact that the ring 10 is permitted to readily slide upon this auxiliary shank 8.

Having thus fully described my invention, What I claim as new and desire to se- 5 cure by Letters Patent is:

In an anchor of the character described, comprising a crown portion having flukes, ears and a shank formed integral therewith, an auxiliary shank formed of an inverted 10 U-shap'ed rod surrounding said shank and In Witness whereof I have hereunto set 15 my hand.
