Description

April 14, 1942.: E.IC. CRAIG ANCHOR Filed June 17, 1940 EDWARD C. CRA/q.

INVENTOR ATTORNEY Patented Apr. 14, 1942 UNITED STATES 'EHQ 'E'ET 1 Claim.

(Granted under the act of March 3, 1883, as

amended April 30, 1928; 370 0. G. 757) This invention relates to anchors and has for its object, among other things, to provide a light weight anchor of high-holding power and being so constructed as to be stowable in a very small space.

It is a further object of this invention to provide an anchor which, while possessing the foregoing characteristics, may be made by casting and thus be kept sufliciently strong to prevent bending of its members during normal use.

It is a further object of this invention to provide an anchor which may retain the benefits of a stock and, at the same time, be capable of being housed in a hawse pipe.

With the foregoing objects in mind, a clear understanding of the invention may be had by a careful consideration of the following specification taken together with the accompanying drawing, in which:

Fig. 1 is a plan view of the anchor, and

vFig. 2 is a side elevational view of the anchor, showing in construction lines the position of the shank when the anchor is in the holding position.

The anchor consists of a shank 3, a fluke assembly and a stock I. The fluke assembly is formed with a slotted crown from the sides of which and integral therewith extend two arms 12 running parallel to the shank and terminating in a pair of flukes 4. One end of the shank 3 is secured for pivotal movement in the slotted portion of the crown by means of a pin H] which may be secured in one of the cheeks of the crown 5 by means of a screw-threaded connection.

Extending from the crown 5 is an ear 6 having a hole running through it parallel to the hole carrying the pin I0. Through this hole is thrust a stock I having its ends bent at right angles to its main part. The stock is secured against movement through the hole, when in use, by means of a collar 8 secured to the stock and normally held close to the ear 6 by a removable pin 9 which passes through a hole in the stock on the other side of the ear. The collar 8 is formed with a flat face I3 which cooperates with a fiat face l4 formed on the top of the When in use the anchor is assembled as shown in full lines in Fig. 1. In dotted lines in this figure is shown the stock I folded alongside the shank for stowage. In Fig. 2, the shank 3 is shown in dotted lines in the position it assumes when the anchor is in holding position on the bottom. The lateral movement of the shank with respect to the flukes is limited by the limits of the slot I5 in the crown 5.

While the provision of only one bent end of the stock is necessary for folding the stock alongside the shank for stowage, both ends are bent in the same manner in order to provide added stability when the anchor is on the bottom.

The invention described herein may be manufactured and/or used by or for the Government of the United States of America for governmental purposes without the payment of any royalties thereon or therefor.

What is claimed is:

An anchor comprising a shank, a fluke assembly and a stock, said fluke assembly comprising a slotted crown, a pair of arms rigidly secured to said crown and extending substantially parallel to each other, each of said arms terminating in a fluke, means securing one end of said shank for pivotal movement within said slotted crown about an axis normal to the longitudinal axis of said shank, means securing said stock to said crown for sliding movement therethrough along a line parallel to the axis of said pivotal movement of saidv shank with respect to said crown, said stock being formed With both its ends bent to lie in the same plane and extend in a direction substantially normal to its length, and means operable at will to hold said stock against sliding movement with its mid-point located within said crown and to hold said stock against rotation with respect to said crown with its bent ends extending in a direction opposite to said arms, said stock when said holding means are rendered inoperative, being slidable through said crown to a folded position in which its central portion lies alongside said shank for purposes of stowage.
