2 Claims. Y 01. 114-206),

The'present' invention relates to new and use-- ful improvements in anchors and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character which will embed itself firmly in the bottom for securely holding a boat connected thereto.

Another very important object of the invention is to provide an anchor comprising means'for absorbing shock and relieving strain when the boat pitches or surges.

Still another very important object of the invention is to provide an anchor of the characdrawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a top plan view of an anchor constructed in accordance with the present invention.

Figure 2 is an elevational view of the device with portions broken away in vertical section.

Figure 3 is a View in horizontal section, taken substantially on the line 33 of Figure 2.

Figure 4 is an elevational view of the lower portion of the anchor, taken at right angles to Figure 2.

Figure 5 is an elevational view of'the rod.

Figure 6 is a top plan view of another form of head which may be used.

Fig. 7 is a view in side elevation of the modified head with portions thereof broken away in section.

Referring now to the drawings in detail, it will be seen that the reference numeral I designates a rod of suitable metal, said rod also being of any suitable length and diameter. Pivotally mounted on the upper end portion of the rod I is a bail 2 for connecting an anchor line (not shown) to said rod. Fixed, as by welding, on an intermediate portion of the rod I is a stop collar 3. Mounted on the lower portion of the rod I is a collar 4 which is secured by a pin 5. I

Slidably mounted on the rod I, between the colis designated' -g enerally by the reference numeral 6. The head 6 includes a tubular shank 1 which is .slidable on the rod I and engageable with the collar 3, said tubular shank comprising an enlarged lower end portion 8 which is substantially conical. Projecting from the portion 8 of the shank I are integral, upwardly inclined arms 9 which terminate, at their outer or free ends, in flukes I0.

Also mounted on the rod I, between the collars 3 and 4, is a coil spring I I. The lower end of the coil spring II rests on the collar 4. The coil spring II is engaged with the head 6 for yieldingly urging said head toward the stop 3. The tubular shank I is counterbored, as at I2, for the reception of the coil spring H. v

Threaded on the lower end portion of the rod I is a pair of locked nuts I3. Rotata-bly mounted on the lower portion of the rod I, between the collar 4 and the locked nuts I3, is a foot I4 in the'form of a horizontally elongated, vertical plate of suitable metal. The foot I4 includes an eye I5 at an intermediate point which is journaled on the rod I.

It is thought that the manner in which the device functions will be readily apparent from a consideration of the foregoing. Briefly, when lars 3 and 4, is ahead of suitable metal which 55 the anchor is dropped the head 6 and the foot I4 rest on the bottom. When pull occurs on the anchor line, the rod I moves forwardly through the tubular shank I, the coil spring II is compressed and the arms 9 with the flukes III thereon are embedded in the bottom. Of course, only the arms 9 which are lowermost will, as a general rule, be embedded in this manner. Should the boat surge or pitch the shock and strain transmitted to the anchor will be absorbed by the coil spring II. When it is desired to hoist anchor theboat is preferably maneuvered to a position substantially over the anchor and the line is slacked to permit the coil spring II to move the foot I4 away from the head 6. Then, when the line is pulled upwardly the rod I functions as a lever swinging from the foot I4 and in this manner the head 6 is freed with comparatively little efiort. By removing the nuts I3 and the collar 4 the foot I4, the coil spring II and the head 6 may be expeditiously removed from the rod I.

In Figures 6 and '7 of the drawings there is illustrated a mushroom head It of suitablemetal which may be slidably-mounted on the rod I in lieu of the head 6. The head I6 has formed therein a plurality of drain openings II forthe passage of water and mud, Of course, in the use of this form of the invention the portion of the mushroom head I6 which is lowermost is embedded in the bottom.

It is believed that the many advantages of a boat anchor constructed in accordance with the present invention will be readily understood and although preferred embodiments of the device are as illustrated and described, it is to be understood that further modifications and changes in the details of construction may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

1. An anchor of the class described comprising an anchor head, a rod having an intermediate part slidingly passing through the head and including lower and upper ends the latter for attachment of an anchor cable thereto, an upper stop on the rod, spring means tending to hold the head against the stop and opposing sliding movement of the rod through the head when the cable pulls on the upper end of the rod to ease the strain on said cable and a bar-like member rotatably connected at an intermediate point on the lower end of the rod, said bar-like memher acting as a fulcrum on the lower end of the rod during initial raising of the anchor oflf the bottom.

2. A boat anchor of the class described comprising a rod having a cable receiving member at its upperend, upper and lower'stops on the rod, an anchor head having a tubular part through which the rod passes with the tubular part having a shoulder therein, a spring encircling the rod and having its upper end engaging saidshoulder with its lower end engaging the lower stop, and a bar-like member having an intermediate portion pivoted to the lower end of the rod below the lowest stop and forming a fulcrum for the anchor during the first part of the lifting motion in pulling the anchor from the bottom.
