Abstract
A first member relatively movable with respect to a second member has a latching mechanism which comprises a pin in a first aperture in the first member in alignment with a second aperture in the second member. The latching mechanism includes spring biasing means for biasing the pin into engagement and lever cam means pivotally connected to an end of the locking pin, and link means against a bearing surface of the first member for retracting the pin against the force of the spring biasing means to disengage the pin from the second aperture. The spring biasing means is contained within a spring housing which is in one embodiment removably mounted on the first member by fasteners such as bolts, and the second embodiment by welding to a guide block mounted on the first member. A control mechanism including a control cable attached to a bell crank which is actuable by means of a shaft manually rotatable by means of a control lever serves to actuate the lever cam means to engage or release the locking pin. A plurality of such mechanisms are actuable by means of a single throw of the control lever.
