STOCKLESS ANCHOR.

Specification of Letters Patent.

Application filed August 12, 1920. Serial No. 402,940.

and useful Improvements on Stockless Anchors, of which the following is the specification.

My invention relates to anchors commonly emp o yed on large vessels and steamships, having a ball on the anchor end of the shank which engages in a ball-socket in the anchor proper, to allow the fiukes to swing parallel on the other side of the shank. a

The object of my invention is to strengthen the anchor about the ball-socket, by increasing the amount of metalat that portion of the anchor, and insert a pin in such manner that the metal removed to admit said in will in no way weaken the anchor at t e base.

I attain this object by the mechanism illustrated in the accompanying drawing, in which Figure 1, is a plan view of the anchor from the side. i

Fig. 2, is a plan view of the ball and shank and a sectional view of the anchor base, along line A.-A in Fig. 1.

Fig. 3, isa lan view of the anchor as sembled fromtie end. j

7 Similar numbers refer to similar parts throughout the several views.

About the central part 1 of the base 2,, which is built in one piece carrying the large fiukes 8-'3, and the small flukes 4-4, all of which are built onto the base and are part thereof, is greatly strengthened by the increase of metal to prevent the large fiukes 3-3 from bending under heavy pull.

In the base and centrally located along the vertical center line, a circular opening 5 is-built, large enough to admit the ball 6 on the lower end of the shank 7, and at the upper end of said opening the inside walls take a form to adapt the ball 6 and form a ball-and socket joint, as shown in Fig. 2, and by the dotted line in Fig. 1.

Since it is necessary to have the angular space 8, opening into, and centrally located at the upperend of the ball-and-socket joint 6, in order that the shank 7 may swing about ball 6, and parallel to the flukes 33, it will be seen that no great amount of metal can be built up atthe points 9-9 as shown in Fig. 2 by the sectional view.

It will be seen in Fig. 1 that the shoulders 10-40, on each side of the shank? are built heavy enough to make up for the loss at the points 9-9, and that a web 11, is built onto and along the lower part of the base, said web 11 is built so as to fall equally on each side of the center line of said base.

At a point on the anchor base 2, low enough to allow a pin 12 to pass at right angles to the base center line, and in the same vertical plane in which the shank 7 has the liberty to swing, about the ball 6, a

hole is drilled to admit the pin 12,- which is for the purpose ofholding the ball 6 in the socket, as shown in Fig. 2 of the accompanying drawing. a

The anchor is assembled in the manner described as following Remove the pin 13, and the ring 14:, which will allow the upper end of the shank 7 to pass through the opening 5 .in the anchor. The shank 7 is drawn through said opening 5 until the ball (S has become engaged in the socket, when the pin 12 is pressed into place and the anchor assembled.

Having fully described my invention, I claim and desire to protect by Letters Patent In combination, in a st ockless anchor, a ball-andsocket joint with means of holding said ball-and=socket joint together by a pin passingunder the ball and at right angles to the base'of the anchor, the center line of said pin being in the same vertical plane in whichthe shank is subject to swing, as hereby described and shown by the accompanying drawing.
