4 Claims.

This invention relates to a boat anchor.

An object of this invention is to provide an anchor which will efliciently operate on different types of lake bottoms, and have good holding ability on every bottom.

Another object of this invention is to provide an anchor of construction and weight that gives good holding power on tough clay, and which will dig into hard-packed sand, as well as having good holding power in soft mucky bottoms.

With the foregoing and other objects in view, this invention comprises certain novel constructions, combinations, and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings:

Fig. 1 is a view in side elevation of an anchor shank 2 is provided with two arms 3, which are turned inwardly at their inner ends 4, Fig. 5, and these ends 4 are secured by bolts 5 to the inner face of the end B of the frame I. A weight I is is within the frame I, in front of ends 4, and this weight is secured in position by means of a bolt ii that extends through the rear end of the frame I. This weight I is cut away at 9 on its top and bottom, these cut-away portions 9 registering with the arms 3 of the shank 2. As shown in Figs. 2, 4 and 5 these cut-away portions are wider and deeper on the side of the member I than at the opposite side. A ring II! is mounted on the shank 2 and slides freely on the arms 3. As is clearly shown in the drawings the diameter of the material of which the ring is made is less than the distance between the deeper end of the cutaway 9 and the adjacent portion of the shank arm 3. The cut-away portions thus permit the ring It to move into position between the weight I and an arm 3, the tapering of the cut-away effecting jamming or gripping of the ring in such position. When the anchor is in use, the usual chain or cable (not shown) is attached to ring I0, and when the anchor is holding the boat in a relatively stationary position, the strain will be on the outer end of shank 2. When the operator wishes to move the boat, he operates the ring I0 until it moves backward on one of the arms 3 until the ring is positioned in one of the cut-away portions 9, whereupon the anchor can be lifted to remove it from its anchoring position. In other words, the lifting position is when the ring I0 is at the rear of the anchor, with the ring having a portion between one of the arms 3 and the weight 1.

Bolts II extend outwardly from the sides of the frame I. with their inner ends extending through the sides. 0n the inner end of the bolts are nuts I2. A washer I3 is on each bolt against the fluke I4 and a nut I5 is on the bolt against the washer I3, Fig. 2. A bushing I6 is on each bolt, Fig. 5, on which is loosely mounted the fluke I4. The washer I3 is against the outer end of the bushing It. The fluke I4 has a relatively free swinging movement on the bushing.

Each fluke I4 comprises an elongated plate having inner and outer flanges I1 and a second flange extending longitudinally thereof at the center section of said fluke plate as a reinforcing rib. Each-fluke plate I1 is cut away at I8. The frame I is also cut away at I9. Whenthe fluke I4 is in its down position, Fig. 1, the cut-away portion I8 will be engaging the cut-away portion I9. When the fluke I4is in its raised position, the cut-away portions I8 will bear against the front edge of the side of frame I.

The bolts II not only provide the means for mounting the flukes on the frame I, butthey also hold the anchor in an operative position, including the preventing of the anchor from turning over, which would retard the function of the anchor by reason of preventing the fiukes from digging into the ground.

While I have described the preferred embodiment of the invention and illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled of plate metal having a central portion and a pair of frame arms extending at right angles from said central position, a shank formed from a strip of' flat metal bent at its center to provide an arcuate portion and having shank arm diverging from the arcuate portion and provided with inturned ends resting on the central portion of the frame, securing bolts extending the inturned ends and frame and holding the shank rigidly on the frame, a ring for cable attachment slidably engaged on said shank, stock arms projecting in alinement outwardly from the frame arms, and fluke members swingingly mounted on said stock. arms.

2. In an anchor of the class described, a frame of plate metal having a central portion and a pair of frame arms extending at right angles from said central position, a shank formed from a stripsof flat metal bent at its center to provide an arcuate portion and having shank arms diverging from the arcuate portion and pro-gidedwith intnrned ends resting on the central portion of the frame,

securing bolts extending the inturned .ends and frame and holding the. shank rigidly on the fra-me,.,a ring for. cable attachment slidably ,engaged .onsaid shank, stock arms projecting in alinement outwardly from the -frame arms, and fiukezmemberseach consisting ofan elongated platejhaving inner and outer flangesand asecond I:
