FOLDING ANCHOR.

MMMMMMMMMMMMMMMMMMMMM NGTON. D C- SAMUEL FRASER LANG-FORD, OF SACRAMENTO, CALIFORNIA.
FOLDING ANCHOR.
Specification of Letters Patent.
Patented Aug. 20, 1912.
Application filed February 1, 1912. Serial No. 674,769.
To all whom it may concern:
, Be it known that I, SAMUEL FRASER LANG- i FORD, a citizen of the United'States, and: resident of Sacramento, in the county of Sacramento and State of California, have invented certain new and useful Improve, ments in Folding Anchors, of which the-following is a specification.
This invention relates to anchors of the type in which the stock is longitudinally movable through a perforation in the shank, so that the stock may be folded against the shank when the anchor is not in use.
The object of the invention is to provide an anchor, of the type in question, with a simple and secure device for maintaining the stock in operative position and preventing it effectually from moving to inoperative position when the anchor is in. use.
To this end the invention consists in the construction hereinafter described, asit is defined in the succeeding claims.
In the accompanying drawings :-Figure 1 is a perspective view of a folding-anchor embodying the present invention, with the stock in position for operation; Fig. 2 is a vertical section, on a larger scale, of the upper portion of the anchor, showing the means for locking the stock in operative position; and Fig. 3 is a side-elevation with the same parts.
The invention is illustrated as embodying in a folding anchor of which the general form and construction is familiar, the anchor comprising the usual shank 5 having a transverse perforation 6 near its upper end to receive the stock 7. This stock is both longitudinally and rotatably movable in the perforation 6, and has the usual curved end 13 to permit it to swing to folded position parallel with the shank.
A lug 8 projects laterally from the stock, and the perforation 6 is made in keyhole form, comprising, at the bottom, a rectangular portion or slot 9. A flange or shoulder 10 upon the stock limits its movement in one direct-ion, through the shank, and in folding the anchor the stock is slid in the opposite direction, the lug 8 passing, at this time, through the slot-portion 9 of the perforation. To look the stock in operative position, however, a resilient tongue 11, in the form of a strip of spring-metal, is fixed, at its lower end, to the shank, and the upper end of this tongue lies normally over the end of the slot-portion 9 of the perforation,
1 thus closing the slot and preventing the passage of the lug 8 theret-hrough.
The shank 5 is provided with a shallow recess in which the tongue 11 lies, so that the outer surface of the tongue is flush with the surface of the shank adjacent the perforation 6. The stock may thus turn freely, but in no position can the lug 8 pass through the perforation. When it is necessary to fold the anchor, however, the resilient tongue is swung away from the shank at its upper end. To facilitate this operation, a notch or recess 12 is provided in the shank, into which any convenient tool may be inserted to pry the tongue away from the shank. When the tongue has been thus swung away, as shown in dotted lines in Fig. 2, the stock may be turned to bring the lug into line with the slot, and the lug may then pass through the perforation, permitting the stock to be moved to folded position in the usual manner. In moving the stock to operative position the operation is reversed, the stock being moved to the position of Fig. 2, thus pressing the tongue away from the shank, and being then turned to remove the lug from engagement with the tongue and permit the latter to snap into place against the shank.
It will be apparent that any pressure of the lug against the tongue, which may result from accidental causes in the use of the anchor, will tend only the more firmly to maintain the tongue in operative position, so that it is impossible for the lug to pass through the perforation except when the tongue is expressly operated to permit this, and thus accidental folding of the anchor when in use is effectually prevented.
My invention is not limited to the embodiment thereof hereinbefore described and illustrated in the accompanying drawings, but may be embodied in various other forms within the nature of the invention as it is defined in the following claims.
I claim I 1. A folding-anchor having, in combination, a shank provided with a transverse perforation of keyhole form, a stock movable both longitudinally and rotatively in said perforation and provided with a lug, and a tongue connected, at one end, with the shank and with its other end normally covering a portion of the perforation so as to prevent the passage of said lug therethrough, the tongue being adapted to be swung away from the perforation to permit the lug to enter the perforation when turned to a position between the tongue and the shank.
2. A folding-anchor having, in combination, a shank provided with a transverse perforation of keyhole form, a stock movable longitudinally and rotatively through said perforation and provided with a lug, and a resilient tongue fixed to the shank and normally covering a portion of the perforation so as to prevent the passage of said lug therethrough, the tongue being adapted to be swung away fro1n the perforation to permit the lug to enter the perforation when turned to a position between the tongue and the shank, and the shank being recessed to receive the tongue, so that the outer surface of the tongue is flush with the surface of the shank adjacent the perforation.
