Abstract
532,554. Emergency exit fastenings. SAFELOCKS, Ltd., BENABO, J., and EDSON, A. D. Sept 7, 1939, No. 25296. [Class 44] In panic bolt fastenings the bolts are held in retracted position by a sliding catch mounted on the casing enclosing the operating mechanism and engaging a notch in a bolt. The invention is applicable to an angle bolt fastening but is shown as applied to a fastening comprising two bolts 16, 17 interconnected by a rocker 20 so as to be operated simultaneously and released by crush bar 16<1> carried by pivoted lever 14, 15. Bolt 16 has a notch 26 engaged automatically by a sliding catch 31 urged by spring 33 to retain the bolts in retracted position. The catch may be withdrawn from inside, to allow the bolts to shoot under action of spring 24, by knob 29 on a stem slidable in a slot in the casing 12, Preferably, also, the catch may be withdrawn by external means forming the subject-matter of Specification 532,579 and comprising a lever 41 pivoted at 67 and operated by moving fingerpiece 40 towards a fixed grip 66. Provision may be made for retracting the bolts from outside by a handle 45 having a lost-motion connection with rocker 20 and provided with locking means as in Specification 532,580.
