4 Claims.

This invention relates generally to ships, and more particularly to a combination anchor bar and bowsprit.

The primary object of this invention is to provide a combination device which functions alternatively as a davit for use in weighing and lowering anchors and as a bowsprit to which a head sail may be made fastv Another object of this invention is to provide a device of this character which will allow the raising and lowering of anchors over the bow of a vessel without danger of damaging the sides of the vessel or the deck, the anchor bar being pivoted on the deck and combined with a windlass and an anchor hatch in such a manner that when the anchors have been raised into engagement with the outer end of the anchor bar, iurther actuation of the Windlass causes the anchor bar to pivot and raise the anchors over the deck, whereafter the anchor bar is fastened in substantially vertical position and the anchors lowered into an anchor hatch, thus generally facilitating the handling of the anchors.

Still another object of this invention is to provide a combination bowsprit and anchor bar which may be utilized as a :bowsprit while the anchors are still secured to the anchor cables, it being understood that ordinarily the anchors will, in this instance, be stored in the anchor hatch.

Still another object of this invention is to provide a device of this character whicn facilitates the provision of a substantially clear forward deck, this device operating perfectly with a windlass housed beneath the deck.

Yet another object of this invention is to provide a device of the character mentioned above which, while primarily designed as a combination bowsprit and anchor bar, may well function as the latter member when combined with vessels other than sailing vessels.

And a last object to be mentioned specifically is to provide a device of this general character which is relatively inexpensive and practicable to manufacture, which is extremely simple and convenient yet safe to use, and which will give generally efficient and durable service.

With these objects definitely in View, this invention resides in certain novel features of construction, combination and arrangement of elements and portions as will be hereinafter described in the specification, particularly pointed out in the appended claims, and illustrated in the accompanying drawings which form a material part of this application, and in which:

Figure 1 is a side elevational View of fragmentary character of a bow of a vessel, with portions broken away and the underlying portions illustrated in vertical section and in side elevation in Order to show the positional relationship of the Windlass, anchor hatch and the other elements of this invention;

Figure 2 is a top plan view of the structure illustrated in Figure 1;

Figure 3 is another side elevational View, similar to Figure 1 except that in this figure the anchor bar and certain other elements are shown in another position, as immediately before the anchors are lowered into the hatch during the storing operation, or immediately before the anchor bar is swung forwardly to carry the anchors over the bow of the vessel, as in dropping anchor;

Figure 4 is a three-dimensional view of What is referred herein as the crossbar comprising means to guide the cables onto the Windlass, together with the block used to mount this crossbar and to mount the anchor bar;

Figure 5 is a central transverse vertical sectional view of the structure illustrated in Figure 4; and

Figure 6 is a fragmentary top plan view of the front end of the anchor bar and the cable guide means on the front end, the figure also including portions of anchor cables operatively associated with the pulleys in the cable guide.

Similar characters of reference designate similar or identical elements and, portions throughout the specification and throughout the several views in the drawings.

Referring now to the drawings in detail, the environment wherewith this invention is adapted to be used includes the bow I!) of a vessel which will ordinarily be equipped with masts and sails, not represented in these drawings, and which will have a deck i2, an anchor hatch [4, a compartment It for a Windlass generally indicated by the numeral It, and the anchor hatch will ordinarily be closed by a hatch door 2!), hinged as at 22 to the deck l2.

An attachement block 24 is apertured, as at 25, to receive attaching bolts whereby this block is secured to the wall 28, separating the anchor hatch [4 from the Windlass compartment, and the upper end of this block extends above the level of the deck 23. The forward upper side of the block 24 is recessed as at 3!] to receive the end 32 of the anchor bar generally indicated by the numeral 34 which is pivoted therein by a transversely disposed pivot pin 36.

The forward end of the anchor bar is provided with a member which is W-shaped in cross-section and referred to herein as a cap 38 which may :be integral with the anchor bar. The cap is open at the top and bottom when the anchor bar is in horizontal position, as indicated in Figures 1 and 2, and a central longitudinal member divides the cap vertically as indicated at 40. A pair of pulleys 42 are freely rotatably mounted between the central member 40 and the sides of the cap, and it will be understood that the cap is rigidly secured on the end of the anchor bar. When two

anchors

44 and 66 of different character are employed, a pair of cables 13 and 50 are entrained through the pulleys i2 and led to the

drums

52 and 54 of the Windlass l8, an idler pulley 56 being used to'guide the cabie concerned to the lower drum 54. Any suitable method of actuating the Windlass may be employed, the drawings illustrating a very simplified structure in which a hand crank 58, a pinion gear 69 and coacting gears on the

drums

52 and 54 are used. Ordinarily, means must be provided for locking the drums against rotation, and this means is represented in the drawings by the dog 52.

A crossbar 54, supported on standards 66 which are rigidly mounted on the block 24, comprises means for guiding the

cables

48 and 56 toward the 'windlass drums, this crossbar 6 extending upwardly from the block 24 and disposed transversely of the vessel, as clearly illustrated in the drawings. The anchor bar carries a hook 63 which is engageable with the crossbar 64 when the anchor bar is in substantially vertical posi tion. Means indicated at 70 for securing the anchor barin horizontal position, that is, with the forward end extending beyond the bow or the vessel, may comprise a sinilple bracket-like member 12, upstanding bolts on the deck 52, and wing nuts 15, whereby the bracl-zet member l2 may be clamlped on top of the anchor bar to hold the same against shifting when this anchor bar is being utilized as a bowsprit, or as a general precaution against damage thereto.

The anchor hatch door 20 may be recessed as at E6 to allow the cables 48 and to extend from the stored anchors tothe anchor bar.

The operation or" this invention will be clearly understood from the foregoing description of the mechanical details thereof, taken in connection with the above recitation of the objects sought to be achieved by this invention. In recapitulaticn, it maybe well to add that dissimilar anchors "E4 and 46 with similar or dissimilar lengths of cables may be used with this invention, provided the Windlass I3 is of proper character so as to allow independent rotation of the

drums

52 and 54, this feature being mentioned merely to-show the versatility of the invention and is not claimed in this application as part of the instant invention. When the anchor bar is used as a bowsprit, the head sail will be indirectly secured to the cap or anchor cable guide 38 at the forward end of the anchor-bar, the construction of this cap being such as to facilitate the securement of a line thereto. In hoisting an a chor or anchors, operation of the Windlass will first raise the anchors into engagement with the forward end of the anchor bar, as indicated in Figure 1. Thereafter, further actuation of the Windlass will cause the anchorbar to pivotabout the pivotal connection 36 into its substantially vertical position indicated in Figure 3, and the hook 68 will be used to secure the anchor bar in this position while the cables 68 and 58 are slacked off to allow the anchors to fall into the anchor hatch i4, whereafter the anchor bar may be unhocked and lowered again into the position indicated in Figure 1, while the anchors are stored. Of course, it is conceivable that the operator of a vessel may wish to detach the anchors [from the anchor cables and G, and in this case the cables are not required to extend to the forward end of the anchor bar and to 4 be returned to the anchor hatch as is necessary when the cables are retained in securement on the anchors and the device is disposed as or actually operated as a bowsprit.

Many minor variations may be made in this invention without departure from the spirit and scope thereof and the said scope of this invention should be determined only as limited by a proper interpretation of the terminology used in the subjoined claims.

Having described the claimed as new is:

1. A combination anchor bar and bowsprit for use with a vessel having a deck, anchor hatch, Windlass, anchor cables and anchors, comprising an elongated bar pivoted at one'end on a deck adjacent an anchor hatch, the other end of the bar extending over the bow of the vessel when in one position, an anchor cable guide on said other end, means adjacent said one end to guide said cables onto said Windlass, means for releasably fastening said bar in said one position, means for releasably locking the bar in substantially vertical position, whereby anchors may be manipulated into and from said anchor hatch and over the side of the vessel, said cable guide comprising a W-shaped member having a central web and side portions of substantially equal lengths on said other end of said bar, said member being open at the top and bottom when the bar is in forwardly extending position, and a pulley mounted on each side of the central web of the W-shaped member so that said W-shaped member is adapted for securement thereto of sail securing means.

2. An anchor bar assembly for use with a vessel having a deck, anchor hatch, Windlass, anchor cables and anchors, comprising an elongated bar pivoted at one end on a deck adjacent an anchor hatch, the other end of the bar extending over the bow of the Vessel when in one position, an anchor cable guide on said other end, means adjacent said one end to guide said cables onto said Windlass, means for releasably fastening said bar in said one position, means for releasably locking the bar in substantially vertical position, whereby anchors may be manipulated into and from said anchor hatch and over the side of the vessel.
