Abstract: FABRICATED CONE CRUSHER                 Abstract of the Disclosure A cone crusher characterized by a frame having a completely fabricated construction, an anti-spin mechanism and an improved crusher setting indicator is disclosed. The frame of the struct-ure, which is composed solely of pre-formed and/or forged members, includes a number of tubular members, a number of annular members and a number of ribs, all of which are welded together to provide a rigid, strong frame. The anti-spin mechanism is characterized by the use of a unidirectional valve and a spring loaded ball valve, thereby permitting the rotation of the mantle of the crusher in one direction while barring rotation of the mantle in the opposite direction unless a force exceeding a pre-selected magnitude is applied to the mantle. The crusher setting indicator, which is used to determine the distance between the movable mantle and the stationary concave of the crusher includes a rod supported by the crusher, the rod abutting the cone support bearing seat of the crusher, the position of which seat is directly related to the position of the mantle. A pinion gear is coupled to the rod and the orientation of the gear is used to provide an indication of the distance between the mantle and concave.      This abstract is not to be taken either as a complete exposi-tion or as a limitation of the present invention, the full nature and extent of the invention being discernable only by reference to an from the entire disclosure.

Abstract: ABSTRACT OF THE DISCLOSURE.            A releasable connector for connecting a shackle bolt on a liferaft to the depending end of a davit cable is set in a safe condition for boarding and lowering of the liferaft.  In the safe condition, a hook member supports the shackle bolt and is itself locked in its supporting position by a latch member.  A coupling spring connected between the hook member and the latch member operates to one side of its dead-center position to urge the latch member into the locking position.  A first downward pull on a lanyard  causes a pawl member to engage a tooth  on the latch member to move the latch member  from its locking position to a drive position in which the coupling spring operates to the other side of its dead-center position and urges the latch member into its drive position.  When the liferaft takes up a floating position on the water, the load on the shackle bolt is relieved and automatic release of the shackle bolt effected under the action of the coupling spring which turns the hook member out of its supporting position.  If the automatic release fails, the lanyard is given a second pull which brings the pawl member, which has returned under spring loading, to engage a second tooth on the latch member and cause the latch member to execute a driving movement in which it displaces the hook member out of its supporting position for release of the shackle bolt.  A first pull on the lanyard results only in the cocking of the connector for automatic release and cannot result in manual release.  A second pull on the lanyard is required to effect manual release.
