F. T. PELKEY ANCHOR File June May 1931.

Patented May 5, 1%31 e r; -65 age. ,a we ,3 t s. a a i A a e FRANK '1. PELKEY, F MARINE CITY, MICHIGAN ANCHOR Application filed June 26,

This invention aims to provide an anchor in which he stock is so connected with the head of the anchor that the fiukes of the anchor will be pitched downwardly and forwardly so as to secure a good hold. An-

other object of the invention is to provide a twopiece anchor the constituent parts of which may be assembled and taken apart readily, without the use of tools.

It is within the province of the disclosure to improve generally and to enhance the utility of devices. of that type to which the invention appertains.

-With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement oi? parts and in the details or" construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope or" what is claimed, without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in plan, a device constructed in accordance with the invention;

Figure 2 is a side elevation;

Figure 3 is a longitudinal section with the stock of the anchor removed;

Figure l is a rear end elevation;

Figure 5 is a front elevation, the stock having been removed and parts being in section. V i

The anchor forming the subject matter 01": this application includes a head 1 from which forwardly extended and approximately parallel flukes 2 project. The head 1 is provided in its rear end with an elliptical opening 3. There is a collar 4 on the head 1 around the rear end of the opening 3. The opening 3 increases in height, as shown at 5, as it extends forwardly, and the opening decreases in width, as shown at 6, as it extends iorwardly, the forward end of the opening being in the form of an elongated rectangle, as shown at 7, there being forwardly tapered recesses 8 within the head 3, at the sides of the opening, the recesses extending but part way through the head from front to back, so that part of the constituent 1929.

material of the head remains in place in the forward and rear ends of each recess, as appears at 9.

This construction greatly enhances the hold of the stock 10 on the body portion of the anchor. The stock 10 is provided at its outer end with an eye 11 and at the rear end of ti stool; there is a ball or sphere 12 which is receiver in the recesses S. The head 1 has outstanding fulcrum flanges 14. The ball 12 on the rear end of the stock 10 en ages in the recesses 8 at a point ahead of the flanges 1%, as indicated in Figure 2, and the result is that the weight of the stock 10 tends to force the forward ends of the fiukes 12 downwardly, as indicated by the arrow in Figure 2. The anchor, as a consequence, naturally tends to acquire a firm hold on the bottom.

Figures 1 and 2 will show that the stock 10 7 0 is of unequal transverse dimensions, the greater transverse dimension of the stock being the vertical dimension. The stock 10 can swing up and down, in a vertical plane, in the elongated mouth 7 of the opening in the head, and although the stock can turn a very little on its axis, there is practically no axial rotation of the stock in the head 1. Because the stool; 10 cannot turn on its axis, the chance of kinking or fouling the anchor line is reduced, provided that the line is paid out fairly and without kinks as it runs through the hawse or through the chock.

It is to be noted that the device forming the subject matter of this application is a simple twopiece anchor, and that the stock 10 can be disengaged from the head 1 by sliding the stock rearwardly in the opening 3, there being nothing in the opening which interferes with the free rearward sliding movement of the stock, thereby to dispose the rear-end of the stock behind, and in spaced relation to, the head, and to change the direction of the leverage of the stock on the head, and to give the rear end of the stock a direct iulcriim bearing on the sea floor. This aids in freeing the anchor when it is fouled, but does not impair the holding qualities of the anchor, because when a vessel rides to the anchor, the pull is in the direction of the stock 10 in Figure 2. lVhen it is desired to free the anchor, if fouled, the vessel simply is set aback, the stock 10 is slid rearwardly from the position of Figure 2, and the changed leverage on the sea floor, hereinbefore referred to, is attained. The construction is such that the anchor can be taken down in a very short time, without the use of tools, and be stowed in a locker in which there would not be room for the anchor if it had to be stowed in theassembling condition shown in Figures 1 and 2.

\Vhat is claimed is 1. 1111 anchor including a head having an opening, the head being provided with forwar lly extended flulr and a stock extended between the ill a and having an enlargement ll'lOllllto "to rock in the openings, (the cross sectional area of the stool: being less than the crosssectional area of the opening) the opening being unencumbered, to the rear of the enlargen ant, and being large enough at its rear end to permit the passage of the enlargement, whereby the stool; can be slid freely in a backward direction, when the anchor is in use, thereby disposing the rear end of the stock behind, and in spaced relation to, the head, thereby to change the direction of the leverage of the stock on the head, and to give the rear end of the stock a direct fulcrum bearing on the sea floor.

2. An anchor including a head provided with forwardly extended flulies, the head having an opening located between the flukes, the opening increasing in height as it extends forwardly, and the forward end of the opening being contracted in width, there being recesses within the head, at the sides of the opening, the recesses being of less area than the sides of the opening and extending but part way through the head from back to front, and a stock of unequal transverse dimensions inscrtable through the opening and held against axial rotation in the contracted forward end of the opening, the stock being provided at its rear end with a ball received removably in the recesses: the opening being unencumbered to the rear of the ball, the re cesses constituting means for holding the ball and the stock spaced with respect to one wall of the unencumbered opening, and the unencumbered rear end of the opening being larger than the ball to permit material, which would otherwise foul the stock and prevent movement of the stock with respect to the head, to pass through the opening.

In testimony that I claim the foregoing as my own, I have hereto atfixed my signature.
