Abstract
226,674. McIsack, H. J. Dec. 27, 1923. Hooks, automatic-release.- A hook D having a spherical head B is supported by two casing members A, A<1> having an internal channel-shaped slot A<2> and hemi-spherical hole A<3> respectively, by which the head B is engaged. A band is fixed by rivets b, b<1>, to the member H, to prevent unintentional separation of the parts A, A'. The member A' is slidable relative to the member A, but is prevented from moving before the hook is loaded by a pin F which pass through the two members. When the hook is loaded, the pressure of the slightly flattened undersurface of the head B on its corresponding seating prevents relative displacement, and the pin F can be withdrawn. A spring H attached to the shackle and to the member A<1> operates this member when the load is supported by the ground &c., so that when the head B reaches the dome of the channel-shaped groove the members A, A<1>, separate and the hood D is automatically released.
