Definitions

  • the present invention relates to a life-boat davit of the type wherein the life-boat is lowered by gravity.
  • An object of the invention resides in providing a davit adapted to swing outwardly during the launching of the life-boat and provided with means for arresting the lowering of the boat in such a position that the passengers entering the life-boat from the deck of the ship will not be adversely impressed with the great height of the life-boat above the level of the sea.
  • Another object of the invention resides in providing a hinged life-boat davit having means associated therewith for limiting the outward swinging movement of one portion of the davit.
  • Fig. 1 is a diagrammatic end view of one of the davits embodying the invention.
  • Fig. 2 is a similar diagrammatic end view showing the davit parts in a position for lowering the life-boats.
  • one of the davits is formed of two bracket parts.
  • the lower part of the davit includes a rigid lever or arm i extending upwardly from the deck 3 of a ship.
  • rigid bracket part I5 is hinged or pivotally secured to the deck of the ship at 2.
  • the upper part of the rigid lever or bracket i5 is provided with a horizontally extending arm is in that this arm is normally in a horizontal position.
  • the upperpartwf; the davit includes an auxiliary lever having a normally horizontal portion 18 and an upwardly extending portion I! which also curves outwardly near the top of the davit.
  • the two parts l6 and l! of the davit are piv0tally connected by means of a hinge l9.
  • the top member ll of the davit is provided with a tackle l for suspending a life-boat 6 therefrom.
  • Means is provided adjacent the hinge 19 for limiting the outward swinging movement of the auxiliary lever ll.
  • Such limiting means may take the form of an arcuate-shaped member secured for example to the horizontal portion l6 of the davit.
  • a davit for launching a boat from the deck of a ship comprising, a rigid lever extending upwardly from the deck of the ship, hinge means pivotally connecting said lever to "the deck of the ship at a point inwardly from the side of the ship, an arm carried by said lever extending substantially at a right angle to said lever, an
  • auxiliary lever having a normally horizontal portion and a portion extending upwardly and outwardly from said-horizontalportion, means pivotally connecting the horizontal portion of said auxiliary lever to said arm, means suspending the boat to the upper end of said auxiliary lever, and means limiting the outward pivoting, movement of said auxiliary lever with respect to said arm.
