IMPRCIIED ANCHOR.

TO ALL WHOM IT MAY CON CERN:

13e it known -that 1, D. C. PIERCE, of Clayton, in the county of Jefferson, and State of New York, have. invented a new and improved Anchor; and that the following description, taken in connection with the accom-i panying drawings hereinafter referred to, forms a full and exact specification of-the same, wherein'I have set forth the nature and vprinciples of my said improvements, by which my invention may be distinguished from all others of a similar class, together with such parts as I claim, and desire to have. secured to me by Letters Patent. I

This invention consists in constrhcting the anchorwith a singleyfluike, pivoted in one end of a frame, which serves as a shank for the anchor, a shackle being attached to the`opposite end of the frame, all being con` structed and arranged in such aomvanner that the cable cannot foul or wind around the iluke or any other part of the anchor, and the fluke made to catch with certainty as soon as-the anchor is let down and the vessel moves a trifle under the action of the tide or wind. In the accompanying sheet of drawings-- Figure 1 is a side view of my invention.

Figure 2, a plan or top view of the same.

Similar letters of reference'indicate like parts.

A represents the fluke of the anchor, which lis formed of a blade-portion, a, and what may be termed a head-portion, b, the outer sur'face of which is convex'. This fluke is secured by a pivot-bolt, B, between one end of two curved bars, C'O, the uke`being balanced, or nearly so, on .the pivot-bolt, and the ends of the bars C C extend between lugs or, projections c e, at each side'of the bead of the linke, as shown clearly in g. 1. The inner side of the head I, from which the blade a of the fluke `projects, is a plane or nearly plane surface. The bars C Care connected at their outer ends bya rod, D, on which a shackle, E, is fitted loosely, and to which shackle the' cable isattnched. The outer Aends 'of these bars are much Afurther apart than the opposite ends, between which the fluke is pivotecl. When the anchor is lowered, the curved bars (1C, which perform the function of a shank and a stock, cause the anchor, .if either bar 'strike Athe bottom first, to turn to a horizontal position, and when the anchor is vmoved\a trifle, under the motion of the vessel, the lower edge of the head b will, inconsequcnce of being in contact with the bottom, turn the point of the blade a down into the bottom, and cause it topenetrate the same, so as to hold the vessel securely The fluke may-he either of wrought or cast iron. Itis believed that east iron 'would answer the purpose. The'lugs 'or projections c c take all strain oil' from the pivot-bolt13 when the vessel is riding at anchor, as will be fully understood by referring to fig. 1.

Having thus described my. invention, I claim as new, and desire to sccureby Letters Patent-H The shackle E, in combination with the bars CIC, and the pivoted iluke A, all arranged substantially as and for the purpose specified.

lThe above speeiliention of my invention signed by me, this 24th day of April, 1867.

D. C. PIERCE.
