IMPROVEMENT IN ANCHORS.

The Schedule referred to in these Letters Patent and making part of the samfe.

To all whom Ait 'ma/y concern: n I

Be it known that LFRE'DERIC Howes, of Boston, in the county of Suffolk, and State of Massachusetts, have invented certain new and useful Improvements in Anchors; and I do hereby declare that the followreference beinghad to the annexed drawings, making a part of this specication, inwhich dierent views of my improved anchor are given.

The objects of my invention are to provide an anchor that will always take hold of the bottom, whatever its nature may be, to dispense with the cumbwus stock commonly used, and to so arrange the anchor that it shall be simple in its construction, not liable to get out of order, and,wl1en catted or taken on board the vessel, Will occupy the smallest amount of space.

To accomplish these results, I make the shank A, to which the arms B Bare rigidly alixed.

Above these arms, and upon a sleeve, a, around' the shank, are two other arms, G O.

The shank is round in its upper part, and square at thelower part, and the inside of the sleeve is fitted to the square portion of the shank, in order to hold the arms C C in the desired position; but I do not conne myself to this method of holding the arms, as it is obvious that vother methods may be adopted. v

Notch'es, b b, are made in the angles of the square portion of the shank, to receive the catches cl (l, which are attached to the arms O G near the throat.

In some anchors I prefer a spring-catch, as shown, but it is ohviousthat the catch may be pivot-ed or go in ways, Without a spring. I

From the outer ends of the catches a'rope or chain, e e, passes tln'ough eye-bolts, as shown, and serves not only to withdraw the bolts when a spring-catch is used, but also to raise up the adjustable arms in order to cat the anchor.

. On the crown and on the arms B B are shown eyebolts, through which a rope or chain is passed, to be used in iishing the anchor, or to attach a buoy-rope.

The shackle I), I make to swivel upon the end of the shank, and hold it by a washer and pin, as shown by the drawings.

The operation of my anchor is as follows:

myself to this form.

In iig. lit is shown with the arms C C directly above and in the same line'with the arms B B, and in this position it occupies the least possible space when it is to be catted or stowed away. lo prepare it for use, the catches c c ane drawn out of the notches b b, and

the arms C C slipped up as far as the round portion` sure which, in all cases, I prefer to make my palm dat,

shown inthe drawings with two bills, h h, so that when two arms-are brought to the ground, the bills will catch and enter. jBut I douot wish to confine The chief feature of my invention is the adjustable arms, so constructed that the anchor requires no stock,

as each pair of arms performs for the other all the 'uuctions required of a stock when the adjustable arms are at rigl'lt angles to the stationary arms, thus securing all the advantages and escapinl all the disadvantages of a four-armed anchor.

rIhe advantage of having the shackle made to swivel on the shank, so as 'to accommodate ,the various positions in which the 'anchor mayfall, and also its positions in catting and stmving, will be apparent without explanation.

What I claim as new, and desire to seciu'e by Letters Patent, is-

l. The adjustable arms, when constructed substantially as shown, and for the pin-pose speciiied.

-2. The combination of the shankfadjustable arms, and catch, substantially as and for the purpose specilied FR-EDO HOVVES.
