Abstract
885,599. Catch gear for garage lifts. ETABLISSEMENTS FOG. Jan. 7, 1960 [Jan. 7, 1959], No. 676/60. Class 78 (3). The corner pillars 3 of a cable operated garage lift are each provided with a row of holes 7 which, in the event of any of the cables 2 breaking, are engaged by simultaneously operating sprags 12, 12a, 12b, 12c carried by the platform. Each sprag is urged towards its associated cable by a spring 11 and is held out of operation by a roller 10 which engages the cable and is mounted in a member 8 pivoted to the platform at 9. The sprags are interconnected for simultaneous operation by a linkage 20-26 and 20a-25a, and each sprag has a lost motion connection with its associated member 8 so that all the sprags operate in the event of a single cable breaking.
