IMPROVEMENT IN BOAT-DETAGHING TAOKLE.

TO ALL WHOM I'l MAY CQNCERN: Y

VBe it known that we, E. C. HURLBUT, of Middle Haddam, in the county of Middlesex, andState of Connecticut, and E. H. SNOW, of Hartford,.in the county of Hartford, and State of Connecticut, have invented a. new and useful Improvement in Detaching Boats from their Davits; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art t'o make and use the same, reference being had to the accompanying drawings forming part-ot. this specification.

The drawings represent a vertical longitudinal sectional elevation of our improvement as applied to a boat.

This invention relates to a new mode of detacliing boats from theirdavits, whereby witha single movement b oats maybe speedily and safely dropped into the water. g

A, in the drawings,rrepresents the boat, which is suspended from the usual davits A,.,by ropes B B and pulley-blocks b b, of the usual construction. The blocks are provided with hooks c e, to receive loo'p ends of supporting ropes or chains c c', whiclrare employed at cach end of the boat and passed through rings d d, located in the front and rear of thcboat respectively. In the central bottom part of the boat is firmly secured a standard, C, to which is pivo'ted at cl the lever D', thc upper end of lwhich' terminates' in a handle, and is passed through a slot, e, in a plank running crosswise and forming a seat of thc boat. To the lever D, above and below thepivotthcreof, are secured rods E, which run horizontally to the front and rear of the boat, and

connect Withthc pivotcd plates F F, which are pivoted at f to standard C C which are attached to the floor of the boat. The lower ends of *the hooks F F pass through holes in vthe projectinglips' G G .of the standards C. The projecting lips G G receive the loops or rings of the extremities of the suspendingropes or chains c' c,-.cnd the endsbf the'hooks F -F pass through the said loops or rings and firmly holdthe said ex tremitics of thc ropes c" c with the lipsl GHG. To prevent the boat frombeing accidentally disconnected, a safety-wedge, ih, is passed into the slot e, wh ich-rmly.-hold s the lever D in its place. i

In disconnecting the boat from its davits, it is necessary to-lower the boatrto a suitable height above the surface of the water, remove the wedge 11, and strike or pull the lever D in the direction of the arrow; thus the ends of the hooks F F become-disconnected, and the boat is safely lowered into the water.. l

Having thus described our invention, we claim as new, and desire to secure by Letters Patent?- The 'combination and arrangement upon the bottom of the boat ofthe standards C C', to which the hooks F F are piv'oted, the Vpoints of thelatter passing through the perforations in the projecting lips G G', thereby securing the looped ends of the chains c c', and operated by means of the pivoted rods E, and lever D, pivoted to thestndard C, in the centre ofthe boat, substantially as described, for the purpose specified.

The above specification of our invention signed by us this 11th day of February, 1867.
