ANCHOR.

SPECIFICATION forming" part Of Letters Patent NO. 451,582, dated May 5, 1891.

Application filed April 17, 1890. Serial No. 348,290. (No model.) Patented in England March 18, 1885, No. 3,476.

To all whom it may concern.-

Be it known that 1, WILLIAM WASTENEYS SMITH, of Newcastle-on-Tyne, England, have invented a new and useful Improvement in Anchors, of which the following is a full, true, and exact description, reference being had to the accompanying drawings.

This invention relates to an improvement in that class of anchors known as stockless anchors.

I have obtained Letters Patent in Great Britain for part of this invention on the 18th of March, 1885, No. 3,476.

My invention will be readily understood from the accompanying drawings, in which Figure 1 is an elevation, partly in section, of my anchor; Fig. 2, an elevation of the same complete; Fig. 3, a view at right angles to Fig. 2, showing a slightly-modified form; Fig. 4, a View at right angles to Fig. 3; Fig. 5, a section through Fig. 4 on the line a: it, and Fig. 6 a view of the anchor shown in Fig. 5 in its working position. v

My anchor consists, essentially, of two parts-the shank and combined cross-head and flukes. I have heretofore, on the 4th day of February, 1873, obtained Letters Patent of the United States No. 135,450 with reference to this class of anchors, a portion of this improvement being likewise shown in English Letters Patent to me No. 3,476 of 1885. The part of my anchor known as the combined flukes and cross-head consists of the flukes F F, which may be of various shapes, as convex or fluted, as shown in Fig. 3. In the body of the crosshead is a slotted box or chamber G, (shown clearly in Fig. 2,) provided with lateral walls H II, within which the shank C operates. The back of the fluke is hollowed out, as at K, and also extended into horns E E behind each fluke. These horns may, if desired, be extended beyond the outside parallel sides of the fiukes. I prefer the form shown, however. The operation of these horns is plainly shown in Fig.7. By them the anchor when in position is provided with four points of support-the horns and the points of the two flukes. The shank O is pivoted in the flukes by bolt L, which can be inserted through the chambers K and lies within the body of the anchor. The fiukes, as will be observed are substantially parallel. The anchor may be provided with a catting-shackle M, attached to the flukes, or with catting-shackle N, attached to the shank. Usually the fiukes are arrested in their motion in the box G at an angle of about fortythree degrees to the shank.

Though I have shown the iiukes substantially parallel, it is obvious they may be spread, if desired.

hat I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, in a stockless anchor, with the shank, of a cross-head pivoted to the shank, and flukes provided with horns E behind the pivotal axis of the cross-head, said fiukes, horns, and cross-head being formed integral, substantially as described.

2. The combination, in a stockless anchor, with the shank, of the flukes and cross-head formed in a single piece, and a pivot or bolt shorter than the cross-head and having its bearings therein between the inner sides of the flukes and extending through the shank, substantially as described.

3. The combination, with the shank, of the cross-head and Iiukes formed in one piece and having the socket G and the recesses K K, and a pin extending between said recesses through the shank, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
