TO ALL WHOM IT MAY CONCERN: -1 5 Beit known that I, THMAS HUNTINGTN, of New Rochelle, in the county of Westchester, 'and State of New York, have invented a new and improved Means for Detaching Boats from their Davits; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable others skilledin' the art to make and use the same, reference being had to the accompanying drawings, forming part of this speciveatiou, in whichj Figure 1 is a vertical section of my in Figure 2, a side view of the same.

Figure 3, a plan or top view-of a boat, with my improvement applied to it.

Similar letters of reference indicate like parts. V i

Thisinvention relates to a new' and improved` means for detaching shipsboats from theirdavits, and has for its object the simultaneous detachment of the hooks of-both the front and rear tackle-blocks from the boat, so that the latter may be set free upon the water without the liability of being'swamped or capsizcd in a swell ord sea. The device is attached tothe front and rear thwarts ofthe boat, and is constructed of a metal plate, A, let in thethwarts, and having two upright lugs or ears a a, between which a right-angular bar or hook, B, is secured by a pin, the former being allowed to work or turn freely onthe latter. AThe hook B extends down through a hole or opening, c,in the plate A7 and has a shoulder, d,-upon it for anarm, e, on a shaft, C, to abut against and keep the upper end of the .hook in about a horizontal position, and near the upper end of a projec' tion,f, on plate` A, as shown in black in figs. 1 and 2. When-the hook B is thus secured in position, the hook D'oi` the davit tackle may be fitted under hook B, and without the possibility of becoming detached unless the arm e is moved down by turning the shaft C, as shown in "red outlinev in iig. 1. The shaft C has its bearings g attached tothe undersides of the thwarts, one or more bearings to each thwart. These bearings hold the shaft firmly in position, and the arms e of both devices are attached to the same shaft so that both arms-will be moved at the same time or by the same movement ofthe shaft C, and the hooks D of both tackle blocks liberated at' the same time, a handle, E, being attached to shaft C for' the purpose of turninpr it. In order to attach the hooks D of the tackle blocks to the front and rear thwarts, the arms e e are turned down so as to release the vention,'taken in the line 'qc il', fig. 2.

hools B, and the hooks D are then inserted under the hooks B. the tops or upper ends of the latter pressed i down, andthe arms e e raised or turned up against the shoulders d, to hold the hooks B in position. TWhen the boat is lowered so that it touches o1' nearly touches the water, the shaft O is" turned by the cockswain or other proper person in the boat, and both hooks D D are instantlyliberated from the hooks B B, and the boat set free.

By this improvement, a. simultaneous'liberation of both ends of the boat is effected; nor by any contingency can one hook D be released before the other, and this is a very important feature, for in case one end of the boat should be liberated before the other end, it would, if there were a swell orsea, be very liable to be capsizcd orswalnped. The hooks D also cannot become casually detached from the hoolis B in lowering the boat. Having thus described my inventioml claim as new, and desire to secure by Letters Patent-- I 1. y'llhe employment or.use of a single shaft, C, arranged with hooks B in ,the manner shown, or in an equivalentway, so that by the turning of said shaft the hooks B may be simultaneously liberated, to detach the boat from the darits.

2. -Tho hooks B, suspended or iitted in the plates A, in combination with the arms e attached to the shaft C, all being applied to the boat, and arranged to operate substantially inl the manner as and 'for the purpose set forth. l

THOS. HUNTING-TON.
