907,686. Hooks. STALLINEFABRIKEN D. AHLQUIST A.B. May 18, 1961 [May 20, 1960], No. 18173/61. Class 89 (2). In a crane or like load-carrying hook including a closing member 3 and releasable holding means, the closing member 3 being pivotally mounted at 4 on the free end 2 of the hook and having the holding means connected to it, the closing member 3 can occupy a position to close the hook or a position in which the hook is open, and is releasable held in either position by the holding means engaging with a part of the hook. In the form shown the holding means is a latch 8, pivotally mounted on the member 3, and can engage a projection 14 on the free end of the hook, so that the member 3 is held either in the closed or in the open position. The member 3 is made of two parallel strips 5 (with flanged portions 6) rigidly connected, and the latch 8 is between them and turnably mounted on the pin 9. The latch is actuated by a spring 12 and has a shoulder 13 for engaging a projection 14 on the free end 2 of the hook, the member 3 being then held in the closed position. The latch 8 has an accessible finger-grip whereby it can be moved to release the member 3 when closed by pressure in the direction of an arrow P. An alternative form of the latch 8 may be used. |
