2 Claims.

This invention relates to an anchor for small boats.

One important object is to provide a separable anchor capable of being collapsed to occupy little space when not in use.

Another object is to provide means for rigidly locking the collapsible portions of the anchor in extended position when the anchor is in use.

Another important object is to provide an anchor that can be manufactured at low cost.

Still another important object is to provide an anchor which will be durable and will embody few parts.

Yet another object is to provide an anchor which will dig into the bottom efiiciently in any position.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawings Fig. 1 is a side elevation.

Fig. 2 is a bottom plan view.

Fig. 3 is an enlarged vertical section.

Fig. 4 is a side elevation of the folded anchor bars.

Fig. 5 is a top plan view of the bottom anchor bar.

Fig. 6 is a top plan view of the center bar.

Fig. '7 is a fragmentary vertical section showing a rib and groove connection between the bars of Figs. 5 and 6.

Referring to the drawings in detail,- a solid upstanding body I has a transverse opening 2 near its upper end. Communicating between said upper end and said opening is an axial bore 3 in which is swivelled a stem 4 integral or otherwise rigid at its lower end with a collar 5 engaging the upper wall of opening 2, the other end of stem 4 being rigid or otherwise integral with a ring 6 for attachment of a cable or the like, not shown.

Integral with the body I at its lower end is the frusto-conical base 1 having the center recess 8 formed in its underside, said recess being threaded.

A bottom bar 9 has a flat center portion integral at opposite ends with upwardly and widely diverging fiukes I0. In the middle of the center portion a top recess H is formed and this is threaded.

Extending radially from diametrically opposite points of the recess II are the ribs [2 formed upon the bottom bar and aligned longitudinally with the longitudinal center line of the bar.

of the bottom bar so that when the bars are aligned longitudinally in their folded position seen in Fig. 4, the center bar will be nested be tween the arms E0 of the bottom bar.

Formed in the underside of the center bar and.

disposed obliquely to the longitudinal center line thereof are the grooves l6 extending radially from a center opening 15 of the center bar, the grooves [6 being complementary to the ribs 12 and receiving said ribs when the bars are spread in angular relation to each other for use.

A top bar I! has a flat center portion and upwardly diverging arms I8, the center portion being shorter than that of the center bar so that all the bars may be nested one within the other as in Fig. 4. The top bar has a center opening registering with the opening l5 and with the recess II. Extending through these registering openings is the stem I 9 of a center connecting bolt, the top and center bars being rotatable relative to said stem, and the lower end of the stem being threaded for engagement in the threaded recess H.

The stem projects upwardly above the bars into the recess 8 and is formed at its upper end with an enlarged threaded head 20 engaging in said recess 8. The stem l9is of a sufficient length that when the head 20 is removed from the recess 8, the bars may be spaced from one another longitudinally on said stem I9 so as to permit their being rotated relative to each other for movement to folded position. This clearance is necessary to permit the rib [2 to drop out of the groove l6.

By means of a weld 2| or the like, the stem I9 is permanently anchored in the recess H.

At a distance from the center opening thereof, the top bar I! has a locking opening 22 formed with an apertured partition 23 midway between its ends so as to define communicating recesses at opposite ends of said opening 22.

A look bolt is mounted in said opening and at one end has an enlarged threaded head 24 threading in looking reces 25 formed in the underside of base 1 adjacent the margin or periphery thereof. The locking head 25 is rigid with the lock bolt 26 extending through said recesses and through the apertured partition. At the other end of said locking bolt is a wing 21 capable of being grasped between the thumb and forefinger for rotating the lock bolt.

When the anchor is not being used, the bars are separated from the body and base by removal of the center bolt from engagement in the recess 8.

The bars are still all permanently connected after such removal. However, since they are now loose upon stem l9 they can be pivoted relative to each other until they are all aligned longitudinally and nested as in Fig. 4. They are now capable of being stored away in a small space. Assuming that the anchor is to be used, the head 20 is first threaded part way into the recess 8 but not to such an extent as will prevent the center and bottom bars from being swung away from their folded positions to positions as seen in Fig. 2.

After the center bolt has been threaded part way in this manner, the locking bolt 26 is threaded into the recess 25. In this connection, it may be noted that when the bars are, folded as in Fig. 4, the locking bolt 26 can be shifted in the direction of its length so as to cause the wing 21 to be recessed in the locking opening, thus to permit the top bar to slide over into position above and in longitudinal alignment with the center bar.

In any event, when the head 24 is threaded into the recess 25 it will lock the top bar fixedly in position against the underside of the base I.

The center and bottom bars, with the rib and groove thereof engaged, are now rotated as a unit and this serves to thread the head 20 fully into the recess 8. The threads are so formed as to cause the center and bottom bars to be related angularly to the top bar in a manner to make the flukes of all the bars spaced equal distances circumferentially of the base I.

What is claimed is:

. 1. An anchor comprising an elongated solid body, a ring carried by said body adjacent one end thereof, a frusto-conical base integral with the body at the end thereof remote from the ring, said frusto-conical base diminishing in crosssection as it recedes from the body, the base having an axial internally threaded recess entering the end thereof remote from the body, an elongated anchor bar, divergent fiukes carried by said anchor bar at opposite ends thereof, a stem carried by said anchor bar immediate the ends thereof, said stem projecting perpendicularly from the anchor bar midway between the fiukes, a threaded head on the stem remote from the anchor bar and threadedly engaging the threads of the threaded recess in the base to hold the anchor bar on the base and the flukes in upwardly and outwardly disposed relation to the base having an axial internally threaded recess entering the end thereof remote from the body, an elongated anchor bar, divergent flukes carried by said anchor bar at opposite ends thereof, a stem carried by the anchor bar intermediate the ends thereof, said stem projecting perpendicularly from the anchor bar midway between the fiukes, a threaded head on the stem remote from the anchor bar and threadedly engaging the threads of the threaded recess in the base to hold the anchor bar on the base and the flukes in upwardly and outwardly disposed relation to the body, outwardly extending ribs carried by the anchor bar on opposite sides of the stem between the flukes, a second elongated anchor bar mounted intedmediate its ends on the stem between the first mentioned anchor bar and the base, divergent flukes carried by the second mentioned anchor bar at opposite ends thereof, said second mentioned anchor bar having elongated grooves therein opening thereinto from the side thereof remote from the fiukes for receiving the ribs and holding the anchor bars against relative rotation, a third elongated anchor bar mounted intermediate its ends on the stem between the second mentioned anchor bar and the base, divergent flukes carried by the third anchor bar at opposite ends thereof, intermeshing means carried by the second and third anchor bars between the flukes for holding said anchor bars against relative rotation, and means carried by the third mentioned anchor bar between a fluke thereof and the stem for engaging the base and holding said anchor bar against rotation relative to the base.
