TO ALL WHOM IT MAY CONCERN:

I, CARL HENRIK RAMSTEN, of Garlskrona, in the Kingdom of Sweden, and now temporarily residing in the city, county, and State of New York, have invented a certain new and useful improvement on Boat-Detaching Tackle, of which the following is a fullyclear, and exact description, reference being had to the accompanying drawing, forming part of this specifica-tion, and in whichi Figure 1 represents a longitudinal section of a boat with my improved detaching apparatus applied thereto.

Figure 2, a sectional view of the same, `taken at right angles' to tig. 1; and

Figures 3 and 4, views on a larger scale (under two modifications of the hook) of a boat-tackle block, in illustration of my invention,

Like letters indicate like parts throughout the several figures. y

This my invention relates to that description of boat-detaching apparatus in which the disconnecting apparatus is in immediate connection with the davit-block, and so as to form an appendage to the same, in contra- `distinction to a fixed connection thereof to the boat, involving a special construction of the latter, with a rod or its equivulentrunuing lengthwise of the boat for detaching the hooks at oppositeends; and the nature Aof my invention consists in a novel combination, with either davitbloclt at opposite ends of the boat, of a lever and jointed hook, forming attachments or appendages to the block, the lever acting as a lock to the hook, which, on

being released, swings or opens independently of the former that is operated, to secure and unlock the hook by a rope or chain, or ropes and chains connecting the two levers of the opposite blocks on the same level, the detaching hooks fitting into oye-bolts, or their equivalents, attached to the boat, and the ropes or chains, which operate the unlocking levers to the separately swinging hooks, being led through fair-leaders, so arranged on the sides or edges of the blocks as to restrain canting or tipping of the latter;' also, it may be, the block being provided with a spring or weighted mousing, that in the riding of the boat admits of the gear of the eyebolts, attached to tlre"boat,1vith the jointed or hinged hooks ol'- the blocks, without allowing of their retraction accidentally.

Referring to the accompanying drawing, A represents a sliips or other vesselsboat, B the davits, and C D the upper and lower blocks of thc falls. E is a lever, running up along one edge'or end of each lower davitblock, and pivoted as at a. Connected with the arms b, to which said levers are pivoted, are separately pivoted,

-as at cl1ooks S, that may either he constructed, as shown at the right hand of g. 1, and in iig.v 4, to lock or be locked by an extension of the levers beyond the fulcrum a, as described in 'Letters Patent of the United States issued to me, bearing date the 23d day of October, 1866, or may be locked by a similar short extension of said lever, locking in connection with an inner extension of the hook, as illustrated at the left hand of tig. l, and in fig. 3, instead of locking on the outer end, arm, or nose of the hook, as referred to. In this latter case, however, it may bo desirable to prevent the unhitchng of the ring or eye-bolt F in the boat from the hook, to furnish the block with a spring or weighted mousing, G, Which, while admitting of the veasy introduction by the closing of thc hook of the eye-bolts, prevents its return or unlocking in the riding of the boat in a rough sea.

` Whatever the form of detachinglhook, however, that may be adopted, it is important that the hooks S, proper,

should he hung so to Swing separately and distinct from their locking levers, and that these separatelyswinging hooks should be distinct from or have no rigid or ixedconnection with the ordinary davit-blocks, that may here be dispensed with, as it is by such construction that a secure hold and easy or certain release of the boat is established. Attached to the upper or opposite ends ot' the locking-levers E are ropes or chains, H, arranged to run through fair-leaders l, formed of small eyelets, pulleys, or blocks, situated one above and the other below, on the inner edges of the blocks D, and connectcthsay the one rope or chain H permanently with a block .or pulley, e, and the other of such ropes or chains running loosely through the same, 3nd,'when required to hold thc boat, lashed round a cleat, or in any suitable manner. By means `of the fair-leaders I, disposed as described, the canting or tipping of the blocks, in attaching-or detaching the boat in a rough sca, is avoided, said fair-leaders having a ccunteracting inward effect on the blocksto the pull Aor strain of the ropes or chains on theupper ends ot' the locking-levers, and serving to keep' the blocks plumb or straight.

Among the various general advantages incidental to lthis improvement, as compared with detaching devices forming appendages to the boat instead of the blocks, are that the invention may be applied to any ordinary boat, and that within a -few minutes, or a spare block be easily substituted for a. damagedaone, and that the boat is not divided or eut up by detaehing devices,nor the letter so liable to be frozen up as if lying Within or at the bottom of the been:7 nor yet so liable to be deranged when situatedelong tlie gunwales of a. boat, 0n the side or ksides of the latter being stove in. In some cases, o1` foi' some pur'posesya.- single block iitted with a lockinglever, separately-pivotal letacliing hook, and fair-leaders, for operation by a single rope orelmin, may be used.

What I claim :is my invention, and (lesite to secure by Letters Patent, is-

A tackle-block, D, provided with{n.leekiilglevex, E, to a. hinged or pivoted detaching hook, S, and fairleziders I, allarranged substantially as described, und for operation, in connection with or by a. rope or chain, H, essentially as specified. l
