To all whom it may concern: removed when it is desired to separate the Be it known that I, PATRICK J. RYAN, a parts of which the anchor is composed. The citizen of the United States, residing in Philasocket 7 of the block 6 constitutes a bearing delphia, Pennsylvania, have invented certain for the inner end of a head 10, formed upon Improvements in Stockless Anchors, of which the shank 11 of the anchor, said head being 5 5 the following is a specification. somewhat wider than the shank, so as to My invention consists of certain improveform ribs 12 for bearing against the shoulments in that class of anchors known as ders 5 of the bridge-piece. While, therefore, stockless anchors, in which the flukes are free swinging movement of the fluke and I0 hung upon a central shank, so as to be free shanks in respect to each other is permitted to swing to a certain extent to either side within the limits of the slotd, the fluke strucof the same, the object of my improvements ture and the shank are firmly retained in pobeing to so construct an anchor of this sition in respect to each other longitudinally character that it will comprise but few and by reason of the bearing of the head of the I5 simple parts, which, While securely retained shank against the block 6 and shoulders 5. in position when the anchor is in use, can be The block 6 is recessed at top and bottom, readily put together or taken apart when 00- so that when it is inserted in the opening 3 casion requires, the free swing of the flukes of the bridge-piece 2 openings 13 are formed in respect to the shank to their limit in either above and below the block, through which 20 direction being provided for and a firm hold openings the water can freely pass, thereby of the flukes of the anchor upon the bottom preventing any such accumula ions of sand being also insured. or mud in the chamber 3 as would tend to In the accompanying drawings, Figure 1 is interfere with the swinging of the shank and a perspective view of an anchor constructed flukes in respect to each other to the full 5 in accordance with my invention.

I-Iaving thus described my invention, I claim and desire to secure by Letters Patent 1. The combination in an anchor, of the fiukes having a connecting bridge-piece with opening therein from the rear, said opening terminating at the forward end in a slot Which is flanked by shoulders at the inner side, a shank having a head with opposite ribs for bearing against said shoulders, a block inserted into the opening of the bridgepiece from the rear and constituting a pivotal bearing for theinner end of the head of the shank, and means for securing said block in and the bridge-piece of the shank, substan tially as specified.

3. The combination in an anchor, of the flnkes having a connecting bridge-piece with opening therein terminating at the forward end in a slot, a shank passing through said slot, and having an enlarged head contained in the opening of the bridge-piece, a block inserted in said opening from the rear and providing a pivotal bearing for the head of the shank, said block having at each side projecting lugs adapted to recesses in the bridgepiece at the opposite sides of the opening therein, and a retaining-bolt passing through the block and its lugs and through projecting rear portions of the bridge-piece, substantially as specified.

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

PATRICK J. RYAN.
