SPECIFICATION forming part of Letters Patent N 0. 399,853, dated March 19, 1889. Application filed January 17, 1889. Serial No. 296,602. (No model.)

To all whom it may concern.-

Be it known that we, CHARLES A. DUREN and EDWIN P. BILLS, both of Boston, in the county of Suffolk, State of Massachusetts, have invented a certain new and useful Improvement in Anchors, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side elevation of our ii'nproved anchor, and Fig. 2 an edge elevation of the same, showing the arms extended.

Like letters and figures of reference indicate corresponding parts in the different figures of the drawings.

Our invention relates especially to that class of anchors which are known as sectional, and it consists in certain novel features, as hereinafter fully set forth and claimed, the object being to produce a simpler, cheaper, and more effective device of this character than is now in ordinary use.

The nature and operation of the improvement will. be readily understood by all conversant with such matters from the following explanation.

1n the drawings, A represents the shank of the anchor, and 1-3 I the arms or blades. The body portion Z) of the blades is dovetailed at (Z to enter a dovetail groove in the shank A, said body being secured thereto by a pin, The opposite end of the shank is provided with an eye, g, to receive the cable in the usual manner. A sleeve, h, is fitted to slide on the shank A, but is prevented from revolv ing thereon by a pin, 2', which passes through said shank and a slot in the lower edge of said sleeve. The sleeve 71. is provided at each side of the shank with lugs 7c, in which one end of a bar, on, is pivoted by means of bolts, which are provided at each end with a nut, 7, enabling them to be more readily removed when rusted by the action of the water.

To the outer end of each bar 111 is pivoted an inwardly-projecting rod, p, the lower ends of said rods being pivoted in ears 'I' on opposite sides of the shank A by means of similar nuts and bolts, Z.

The blades b are constructed without flukes to enable them to more readily enter the ground and prevent the cable from fouling or catching on them.

In the use of our improvement the sleeve h being keyed by the pin 2', the bars in and rods 1) are extended as shown in Fig. 9, and tend to direct the bills or points of the blades into the ground when the anchor is lowered. They also serve to prevent the anchor from turning and becoming disengaged from the ground.

By employing the rods 2) it is rendered impossible for the cable to foul or become entangled with the anchor and accidentally trip it, as frequently occurs when the ordinary stock is used in place of the bars in.

It will readily be seen that by removing the pin 1' and sliding the sleeve h on the shank, so that the par s occupy the position shown by dotted lines in Fig. 2, the anchor will occupy much less space on the deck than when of ordinary construction.

It will also be seen that should any of the parts become accidentally broken they can be quickly replaced by duplicate parts.

Having thus explained our invention, what we claim is 1. In an anchor, the shank A, provided with an eye in one end and a dovetail groove in its opposite end, .in combination with the blades l3, provided with the dovetail (Z, and the pin f, for securing said blades to said shank, substantially as described.

In an anchor, the combination of a shank having a cable-eye at one end and a dovetail groove in its opposite end, smooth blades hav ing their body portion dovetailed to enter said groove, and a pin for securing said shank thereto, substantially as described.

3. In an anchor, the combination of a shank provided with smooth blades, a sleeve fitted to slide on said shank, bars pivoted in lugs on said sleeve, rods pivoted to said bars and shank, and a pin for securing said sleeve in position on the shank, substantially as described.

a. In an anchor, the combination of a shank provided with a dovetail groove in its lower end, smooth blades having their body portion dovetailed to enter said groove, a pin for securing it therein, a sleeve fitted to slide on said shank and provided with slots, a pin passing through said shank and slots, at bar pivoted in ears on said sleeve at each side of the shank, and a rod pivoted to each bar and to said shank, substantially as described.

5. An anchor having" its stock pivoted to the shank, and a rod pivoted to each end of the stock and to said shank, whereby the cable is prevented from fouling said anchor, substantially as described.

' 6. In an anchor, the combination of the shank A, having the eye 9 and a dovetail groove in its opposite end, the blades B B, having the dovetail d, the pin f, for securing said dovetail in said groove, the sleeve h, provided with lugs 70, the bars m, pivoted in said lugs, the rods 1), pivoted to said bars and shank, and the pin 7;, for securing said sleeve in position, all being arranged to operate sub stantially as setforth.
