T0 all whom it may concern: 4

Be it known that I, JOHN WATSON, a citizen of the United States,residing in Chester, Pennsylvania, have invented certain Improvements in Anchors, of which the following is a specification.

The object of my invention is to construct what is known as a stockless anchor that the fluke structure can readily swing upon the shank and which will at the same time be within the chamber of the fluke-section in which the end of the stock works. This object I attain in the following manner, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view illustrating myimproved stockless anchor. Fig. 2 a sectional plan View. Fig. 3 is a rear view. Fig. 4 is a side view, partly in section; and Fig. 5 is a sectional perspective view showing parts detached.

A is the head of the anchor, preferably rounded at each corner, and extending from this head are the flukes a a. Theseflukes are spread outward, so that they will more readily retain the anchor in its fixed position when on the bottom.

B is the shank of the anchor, of any suitable The shank B is curved at its inner end I) and has two overhanging flanges I), also curved to conform to the arc of bearing-blocks (l d on each side of the opening 0 in the head Afor the passage of the shank, so that a snug fit is insured between these flanges and the bearing-blocks. In fact the flanges travel in grooves f, formed by the bearing-blocks and the outer casing cc .of the enlarged portion A of the head, as shown in Fig. 4:, so that the shank is held in proper position always in respect to the head.

At the rear of the enlarged portion of the head is a cap-plate a resting on shoulders at of the casing, Fig. 5, and held in place by pins a On removing the cap-plate a the shank can be detached from the head.

The channel fcommnnicates at each end with a passage f, so that any mud or other foreign matter gaining access tothe chamber in which the head of the shank travels will he forced out through these openings f, and thus the chamber will not become clogged, as is the case in some anchors of this type. Furthermore, the shank when the anchor is in engagem-entwith the bottom closes the opening in the head through which it passes, so that mud or other foreign matter cannot gain access through the shank-opening in the head of the anchor. The anchor will readily free itself of mud, and by the form of the head mud cannotaccumulate at the junction of the flukes with the head. ening-ribs c c on the head A. These maybe used, if desired, althoughthey can be readily dispensed with on small anchors.

By my improvement I provide the shank with a curved T-head adapted to work on the curved bearing in the head of the fluke-section, forming What may be termed a swiveljoint. At the same time the fluke-section and shank are held rigidly against lateral motion not only by the neat fit of the T-head of the shank in the groove f, but the fit of the shank itself between the side walls of the bearing-blocks d. t

I claim as my invention 1. The combination in an anchor, of the fluke-section having an opening for the passage of a shank, grooved bearing-blocks on each side of the opening, with a T-headed shank adapted to the opening in the flukesection, thecurved head of the shank resting on the bearing-blocks, substantially as described.

2. The combination in an anchor, of the fluke-section, an opening therein for the passage of the shank, said section having curved bearing-blocks at each side forming, with the back of the fluke-section, grooves, with a shank having a curved T-head adapted to the grooves,and resting upon the bearingblocks, with a removable plate secured to the back of the fluke-section, so that when this plate is detached the shank can be removed, substantially as described.
