ATTACHMENT FOR ANC HORS.

SPECIFICATION forming part of Letters Patent No. 427,347, dated May 6, 1890.

Application filed August 27, 1889. Serial No. 322,081. (No model.)

['0 aZZ whom it may concern.-

Be it known that I, HOWARD L. MOULE, of Rock Creek, in the county of Albany and Territory of Vyoming, have invented a new and Improved Attachment for Anchors, of whichthe following is a full, clear, and exact description.

My invention relates to an improved attachment for anchors, and has for its object to provide a means whereby anchors of ordinary form, which are too light for efficient service, may be readily and cheaply increased in weight at a point where it will be most available to render the anchor reliable in use.

TVith this object in view my invention consists in the provision of a clampinggravityblock, which is secured in place so as to embrace the crown and shank of the anchor, whereby the weight of the crown-piece will be so increased as to insure the embedding of the flukes and proper retention of the anchor.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side view of an anchor in position for use, showing my improvement secured thereon. Fig. 2 is an edge View of the same, partly in section, on the line so .90 in Fig. 1. Fig. 3 is a plan View of the anchor, partly in section, on the line y y 'in Fig. 2 and Fig. 4 is an enlarged view of a portion of the improvement detached from the anchor.

The ordinary form of anchor is preferred for general use on account of its simplicity and peculiarity of form, which latter adapts it to hold firmly when in use and be snugly as well as securely stowed when hoisted to place at the side of the vessels bow.

It is necessary for the proper operation of an anchor that its weight and spread of flukes able to hold a vessel of greater tonnage than it was originally designed for, I have provided the clamping-blocks B B. These blocks 5 5 are constructed of cast metal, and as the two pieces are duplicates a description of one will suffioe for both. As will be seen in Fig. 4, the half-section B is recessed at B B thus adapting the piece to conform to one-half the thickness of the anchor-shank A and crown portion 0. The standing portions B and their rounded front ends d, respectively, hug the opposite sides of the shank A, and fit against the juncture of the shank and crown when in position, as indicated in Fig. 3, where both sections are shown in secured adjustment upon the anchor.

The form of the gravity-block is notimportant, but that shown is preferred, as it 7 affords weight properly disposed and in compact shape, this being the main essential to be provided.

The duplicate sections B B, as shown in Fig. 2, embrace the shank A, as well as the crown, and are slightly separated to permit a clamping action of the pieces upon the parts mentioned. A suitable number of bolts F are inserted through transverse holes made in the pieces or sections B B, which bolts have conical heads b and squared nuts 0 seated in recesses provided in the sections, so that by a proper manipulation of the nuts the sections will be firmly secured in position, and no improper projections extend beyond the 5 general surface of the sections to catch the cable or foul the anchor with other ropes or chains when it is being hoisted or cast overboard.

By the provision of the gravity-block just 9 described any light anchor, if otherwise strong enough, may be given the weight necessary to embed its flukes and retain them so engaged, which will prevent dragging of the anchor in an obvious manner.

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

1. An attachment for anchors, consisting of two recessed sections which embrace and are I00 secured on the shank and crown of the anchor, substantially as set forth.

2. An attachment for anchors, consisting of two equal recessedhalf-sections clamped upon the shank and crown of the anchor, substanclamped on an anchor, substantially as set tially as set forth.
