GEORGE A. LLOYD AND CHARLES A. STEWART, OF SAN FRANCISCO,

CALIFORNIA.

Letters Patent No. 66,665, dated July 9, 1867.

IMPROVED ANCHOR.

TO ALL WHOM IT MAY CONCERN:

Be it known that we, GEORGE A. LLOYIS and CHARLES A. STEWART, of San Francisco, State of California, have invented certain new and useful improvements in Anchors; and we do hereby declare the following descrip-` tion and accompanying drawings are snicient to enable any person skilled in the art or science to which. it

most nearly appertains to make and use our said invention or improvements without further invention or experiment.

The nature of our invention and improvements in anchors with swinging ilukes consists in making lugs on the arms or ukes to strike'or come against projections or stops on the 'shank of the anchor, when the ilukes have swung a proper distance either way to catch and hold to advantage in the anchoring ground, and in making the ilukes t-o stand at different angles, so that one will catch rst when the anchor is one side np, and the opposite one when the anchor is the other side up. In the accompanying drawings- Y Figure 1 is an elevation of one side of an anchor with our improvements. i

Figures 2 and 3 are elevations of the anchor, as seen at a right angle to fig. l in iig. 3. One of the dukes is cut oi on the line e e of fig.. 1. p I

In these drawings, A is the shank of the anchor, provided with a olevis, B, for attaching the cable in the usual manner. The lowerpart of the shank is enlarged and perforated to permit the insertion of one of' the linkes, and a groove is cut in the upper side of the hole wide enough to let the fluke pass through when it is pnt in. This groove is lled bythe key e after the fluke is pnt in and the key fastened by the pin f, liig. 1. The ilnkes have wide lattened ends at D D to holdin the mud or bottom, and are made round at C C, with lugs or projections@ a,whicl1 strike or come against the stops d d on the shank, when the iiukes have vibrated far enough in either direction to catch and hold to advantage when the anchor is dropped. The stops d d are forged with the shank, which may he extended below the iinkes and perforated at y for a becket, or to apply a clevis, if desired Fig. 2 shows that` the lukes are not both in the same plane, but stand'at different angles, so that when the anchor is dropped one side'np, one of the iinkes will catch Erst, and when dropped theoth'er side up the other iiukc will catch first.

Having described our improvements, we clam The lugs a a on the linkes, in combination with the stops or projections d d on the shank for the purposes set forth. i l

We also claimrm'aking the dukes to stand at di'erent angles, so that one will catch first when the anchor is one side np, and the opposite one when the anchor is the other side up, substantially as described.

In witness whereof we have hereunto set onr'hands and aiiixed our seals.
