l IMPROVEMENT IN ANCHORS.

Specification forming part of Letters Patent No. 112,247, dated February 28, 1871.

p To all whom it may concern:

i y ters of reference marked thereon.

My invention relates to that class of anchors which is employed without stocks, and is so constructed as to hold with both ilukes, the object of which is to provide an anchor that will Vhave great holding power in proportion to its.

weight, non-liability to fouling, will be easy to cat and iish, and certain to bite when a strain is applied; will have no flukes standin g y up out of the ground ready to go through the bottom of a ship, or always likely to catch the bight of the chain as itis dragged around when a gale arises and a ship swings to her anchor, and will at the same time have superior strength and simplicity.

This invention consists in making the shank of two similar curved pieces or rods, hinged to a shackle or ring-plate and to heart-shapedflanges or disks at the throat or crown of the anchor in such a manner that the curved pieces or rods,langes, and shackle-plate may move 1n relation to `each other exactly like correspondin g parts of our ordinary parallel ruler,

the heart-shaped ian ges being formed in one piece with or rigidly and securely attached to the arms in such a position that the flukes or palms will bethrown or directed from one side to `the other of the line of the shank bythe movements ot' `the parts of the shank actuated bythe cable in the ring or shackle plate, as

y hereinafter more fully described and shown.

In the annexed drawing, Figure 1 is a side elevation of an anchorhaving my improvement. Fig. 2 shows the heart-shaped flange; Fig. 3, one of the rods forming the shank.

Like letters refer to like parts in all of the figures. i

A A' are the parts ofthe shank. BB are parallel heart-shaped angeplates, formed of one piece with the arms C C. D is the ring or shackle plate, provided with small flukes or platesE E. F are the lioint pins or rivets by which the parts AA of the shank are hinged to the shackle-plate D and (iianges B B.

It is obvious that if my anchor should drop to the bottom in the position shown in Fig. 1, the weight of the chain would carry the upper part over, `and the ilukes or palm E would penetrate the ground vand act as a fulcrum, over which, when a strain was brought upon the cable, the shackle-plate would be drawn, bringingA the rod A', and, consequently, the arms C' and lukes of the anchor, over with it, and the ring G ofthe cable, slipping up the grooveor slot H of the shackle-plate, would Cause the dukes of the anchor to penetrate the ground. By this construction, also, of forining the shank in two parts, it will be seen that the curved .ends Y of the shank will elevate the head and secure a better angle for penetration of the dukes, as well as providev a recess against which the throat rests when in position, and when the power is applied the ring of the cable will ascend the inclined link until it comes in line with the leverage or strain, and not have the tendency to lift the ilukes of the anchor from the ground.

Having thus described my invention, `what I claim, and desire to secure by Letters Patent, is

1. An anchor having the double shank A A',

anges B B, the shackle or ring plate D, with the ilukes E E and grooves or .slot H, and the rivets or jointpins F, when combined and arranged to operate substantially as herein described.

2. The combination of the shackle-plates with the lukes E E and the double shank A A of the anchor, as described.

In witness whereof' I have hereunto set my hand and seal.

WM. M. HUGHES. [L. 5.]
