A chock wherein a movable inner member is received for relative vertical movement in a housing with the inner member having a conventional diagonal slot therein for receiving a line. The housing has a central counter bore at the top thereof, and a smaller bore extending therefrom and said inner member is received in the housing for relative axial movement between a depressed inoperative position and an upper operative position. A set screw carried by the housing engages a slot in the inner member for limiting relative axial movement therebetween, while a spring loaded poppet carried by the housing is engageable with a detent near the bottom of the inner member to resiliently hold the inner member vertically stationary relative to the housing when in its upper position.

[ What is claimed is:] [1.]1. A chock having a raised operative position and a depressed inoperative position, comprisingA) a housing including an attaching flange and a base portion extending downwardly therefrom,B) a vertically movable member having an enlarged upper end and a lower end with said lower end formed integrally with said upper end and extending downwardly therefrom, and said lower end being smaller in cross sectional area than said upper end,C) said housing having an upper counterbore and a lower bore extending downwardly therefrom and having a shoulder between said upper counterbore and said lower bore,D) said movable member having a raised operative position and a depressed inoperative position and, when in its depressed position, having the enlarged upper end fittingly received in said counterbore of said housing and having the lower end fittingly received in said lower bore,E)a detent formed in said lower end of said movable member with said lower end having a side thereof adjacent said detent,F) a spring loaded poppet disposed in said shoulder and engageable with said detent when said movable member is in its upper position, and said poppet resiliently engaging said side of said lower end of said movable member that is in vertical alignment with said poppet when said movable member is in its lower position,G) a vertically elongated slot in said lower end of said movable member, andH ) a first adjustable set screw disposed in said shoulder and engageable in said slot to limit upward movement of said movable member relative to said housing, said housing has a second laterally extending threaded opening therein removably receiving said first adjustable set screw, with said first adjustable set screw being removable from the exterior of said housing so that said chock can be disassembled, and wherein said set screws are coaxially aligned.
