593,776. Hatches. LAMOTHE, O., and LAMOTHE, J. A. June 12, 1945, No. 14909. [Class 113 (i)] An adjustable clamp for retaining in place the tarpaulin securing battens of ships' hatches, consists of an extendable bolt 8 operated by a corrugated cam 17, one or other of the corrugations engaging a notch 15 on the bolt to lock it. A smaller auxiliary cam is carried and operated by the same means as the main one, for retracting the bolt and a larger corrugation 20 prevents excessive rotation of the cam.
