SHIPS ANCHOR.

SPECIFICATION forming part of Letters Patent No. 653,861, dated July 17, 1900.

Application filed M y 5,1399. :serialllo. 715,751. (NomodelJ T0 ctZZ whom, it may concern.-

Be it known that I, JOHN CALLOW, a citizen of the United States, residing at New Kamilchi, in the county of Mason and State of Washington, (post-office address asabove,) have invented certain new and useful'lmprovements in Anchors; and I do hereby declare the following to be a full,'clear, and exact description of the invention, such as. will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in anchors, and has for its object to produce an anchor with means for spreading its flukes to enable it to take a better hold in sandy or muddy bottoms.

With this object in view my invention consists of an anchor-body of usual outline provided with supplementary flukes slidable within the ordinary fiukes so as to fold within or spread therefrom, and which are suitably connected to a spring-pressed operating-bar carrying the cable-ring and adapted to be locked in its several positions by a pawl operated from the ship.

With these and other objects in View my invention further consists in the novel details of construction and combination of parts to be more clearly described in the following specification and fully set forth in the claims.

In the drawings forming partof this application, in which like characters of reference indicate similar parts throughout, Figure 1 is a central vertical sectional view of my improved anchor. Fig. 2 is a similar section taken at right angles to the plane of Fig. 1. Fig. 3 is a broken front elevation of the anchor,"and Fig. 4: is a transverse sectional view on the'line a; a: of Fig. 2.

In the drawings I represent my'improved anchor as consisting of a casing formed of two sections 1 l, bolted together to form an anchor of usual outline, with the ordinary stock 2 rigidly attached thereto. An operating-bar 3 is slidably mounted in the stem of the casing and is given a downward pressure by means of the spiral compressionspring ec'oiledthereabout and attached thereto'at its lower end, with its upper end seated against the extremity of the hollow chamber 5, in which it is located. To the upper end of the operating-bar is swiveled a cable-ring and by which the operating-bar may be slid spring 4 when occasion requires. A springpressed crankfpawl 7 is pivoted to one section of the casing and is adapted to be nor:- mally engaged with the teeth of a rack-bar 8, carried by the operating-bar to lock said bar in any desired position, but which may be thrown out of such engagement by a pull on the line 9 of the stem 10, which is pivoted to the crank of pawl 7 and protected by the housing 1l Supplementary flukes 12, substantially triangular in shape, are pivoted at their outer corners to the outer corners of the ordinary flukes, so as to be capable of folding in said ordinary flukes or to be spread by swinging on their pivots to increase the engaging sur face of the anchor. Rods l3 connect the in ner ends of the supplementary fiukes to the lower end of the operating-bar, so that when said bar is in its lowermost or normal position the supplementary flukes willbe folded within the casing; but when the operatingbar is drawn'up against the action of the spring, while the pawl 7 is released, the supplementary flukes are distended by means of the rods 13 swinging them on their pivots.

From the foregoing it will be seen that when an anchor of my improved type is dropped in the ordinary way and is embedded in soft ground, but continues to drag, the operator draws on the line 9, releasing the pawl from the ratchet, when the further draft on the anchor will cause the operating-bar to slide within the casing 4-, distending the supplementary fiukes and increasing the engaging surface of the anchor to secure a better anchorage, and the pawl is released to lock the operating-bar and hold the parts in this position. When it is desired to weigh anchor, the anchor-cableis slacked and the pawl released by drawingon the line as before, when the spiral spring t returns the operating-bar to its normal position, thereby withdrawing the supplementary flukes and leaving the anchor to be weighed as usual. Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-'=- 1. In a device of the character described, a

' 6, adapted to be engaged by the anchor-cable ICC casing provided with flakes, supplementary flukes carried thereby, and means for spreading the supplementary flukes, substantially as described.

2. In a device of the character described, a casing having flukes, supplementary flukes carried thereby, and a spring-pressed bar slidable in the casing and connected with the supplementary flukes, substantially as described.

3. In a device of the character described, a casing provided with flukes, supplementary flukes carried thereby, a spring-pressed bar slidable in the casing and connected with the supplementary flukes, and means for locking the bar in its several positions, substantially as described. I

4:. In a device of the character described, a casing provided with flukes, supplementary flukes carried thereby, a spring-pressed bar slidable in the casing and connected to the ed in the casing, means connecting the lower end of the bar with the supplementary flukes, a cable-ring at the upper end of the bar, a. spiral spring surrounding the bar and housed in the casing so as to give the 'bar a normal downward pressure, a rack-bar carried by the sliding bar, a pawl pivoted in the casing to engage the rack-bar, and a stem pivoted to the pawl, substantial] y as described.
