This invention relates to anchor davit devices and has for its ob ect the provision of i eaus "for raising and lowering a ships anchor with a minimum of effort and with- 5 out injury to thevessel. I i

A further object of this invention is the provision of means whereby the anchor may be automatically lockedin position on board the vessel when raised.

in A further object of this invention is the provision of a support for said anchor and f means whereby said anchor automatically positions itself upon said support when the former is raised;

Other objects and advantages will herematter appear.

Li.) Fig. 7 is a view similar to Fig; 6 but'sho wing the anchor raised and properly/positioned relative to the support.

v Fig. 8 is a view similar to Figs. 6 and 7 but showing the support beginning to swing toward the carriage. w r Fig. 9 is a front elevation, gpartly sectioned. of the member whereby the support is connectedto the carriage.

Fig. 10 is adetail of one of the positioning members on the upper portion of the support. I

Fig. 11 is a front view otthe positioning members on the upper end of the support.

Referring to the drawings, there is shown as an anchor havingarm's'lil at one end of the shank and a ring 12 at .the other end of the shank, the plane o'fsaidring being substantially the plane of said arms; Ajcable 15 is'attach'ed at one end to the ring 12 and a cross-bar-or rod 16 is passed through said cable near the ring so that said rod is substantially in the plane of said ring. The other end of'the cable'is connected to'a winch or other winding mechanism. J

For supporting the anchor there is provided a support'2O having apulley '21 at its upper end over which the cable passes, and having a' plate 22 at itsl'ower end for supporting the arms 11 of the anchor. The "support 2 0 is pivotally connected by a bracket 2t fixed thereto to acarriage 25 which is mounted by

anti-friction rollers

26 and 27 between upper and lower rails 28 and .29 fixed to the vessel. When the anchor is ineffective it rests upon the support 20 which in turn rests upon the carriage, as shown in Fig. 2." A cable attachedto any suitable winding mechanism may be provided for drawing the carriage outwardly upon the' deck of the vessel tot-he Fig. 2positio1i, said outward jino'vement being limited by suitable stops 35. In this position the heavy arms ll of the anchor project over'the sides ofthe vessel so that when the cable 15 is released the anchor Willfbv its own weight, rot-ate the support 20 about bracket 2430 that the anchor .may fall freely. To limit the outward movement of support 20 there .is provided at each side of said support a linkage 30 pivoted at one end to the upper end of the support at 32 andat the other end at 33 to a bracket 34;"fixed to the carriage Means are provided whereby the anchor, when drawn up, positions itself properly upon the support .20. Said means comprises 9 a plate 37 fixed tothe upperend of the support in a plane parallel .to the plane of plate :22, so that as cross-bar 16 and ring 12 contact with plate37 the latter will turn them, and hence also the anchor arms, until their plane coincideswith that of plate 22, so that when theanchor is any drawn up, both arms 11 vvillcome to rest simultaneously upon plate 22, The upward movement of the anchor is limited by the engagementnf we cross-bar 16 in jaws 39 at the outer ends of link 30. Further winding of the cable after the engagement of the bar 16 in jaw s39 will rotate support 20 inwardly until the arms ll of the anchor rest upon plate 22 and a tongue 40 on plate 37 projects through ring l2 to preventlateral movement of the latter. At the same time a tongue 46 at the end of each linl: engages in openings 47 in plate 237 and projects therethrough to prevent downward slipping of the bar 16, and hence of the anchor, since said tongues a6 will engage said bar and prevent said downward movement. 7

After the anchor has positioned itself upon the support, further winding of the cable 15 will rotate the support about the, pivot of bracket 24- inwardly upon the carriage. Since the distance between pivot and the upper end of the support is shortened as the support rotates inwardly, each link 30 comprises two sections 41 and 4-2 pivot-ed together at 43 so that section ail. may'rotate about pivot 43 in a counterclockwise or inward direction and fold upon section 42. lVhen the anchor is lowered and support 20 rotates outwardly, section ll rotates outwardly about pivot 43, said out ward rotation of section ll being limited by the engagement of a pin 44; on an extension of section 4-1 in a groove 4:5 in section 42.

The anchor and support being rotated to rest upon the carriage, the latter may be drawn inwardly by further winding of cable 15. To prevent the anchor slipping oil the support due to rolling of the-vessel, guards 50 may be fixed to either side of the support, the lower ends 51 of said guards extending between the arms 11 to prevent lateral movement thereof.

The above description illustrates a pre-- terred embodiment of my invention, but

Various changes may be resorted to within the scope of the annexed claims.
