@Ligt Sdgemlt .tefetteh it im inst ttters tteut mit mating putt tf tige stmt.


Be it known .that I, GEORGE II. KEMP'LON, ci' the eity of Hudson, county of Hudson, State of New Jersey, have invented a new and useful Life-Saving Apparatus forhoisting and lowering boats from vessels in distress. I do hereby declare the following is a. full and exact description, reference being had lto the annexed draw'-` ings, making a part of this specification, in which- Figure 1 is a. perspective view as attached to end of boat hanging at the davits.

Figure 2 is a side view, and

Figure 3 a full vieiv of hook. v

The hook (as seen at iig. is made with the upper ends or balls A A so heavy alsto open the hook at B I when the boat 1) shall 'strike the water, the chain andi-ing C'C C supporting and drawing the hook more tightly together as the weight of the boat or in the boat is increased. The chain I), as drawn from one side of hook to the other, is used for safety in rough weather and in va heavy sea.. case of fire, leak, or abandonment during good weather, the chain D may be attached before lowering the boat, or while lowering the boat, butduring the operation of lowering in a heavy sea, the chain D operates as a check to the sudden opening of the hook until the boat is ready to be detached from the vessel, when, by lifting the chain from the pin E, or by drawing a pin at E, the hook frees itself, by the fall of the balls in opposite directions.

Fig, 1 represents the hook as attached to a boatreudy-or launching, ,with the hook fastened in the Vringbolt, when, by relieving it from the weight of the boat, and lifting the chain D from the pin E, orv drawing a pin atl E, the Weight of theuballs A A immediately frees the hook from the boat. I

What I claim, and desire to secure by Letters Patent, is

The application of the double-weighted hook to the ring and chains C C D, all combined and operating for the purposes specified.
