Abstract

472,042. Fastenings. TIBBLES, H. J., and RELY-A-BELL BURGLAR & FIRE ALARM CO., Ltd. March 1, 1937, No. 6009 /36. [Class 44] In a pivoted casement fastening the locking arm 1 is retained in the looking position by a detent 10 carried by a spring arm 9 and provided with a cam face 11 to enable the arm 1 to displace it when moving into the locking position. The arm 1 rests in a recess 10<1> on the upper surface of the detent. A finger-piece 13 moves the detent away from blocking position when the arm 1 is to be released. The detent may engage a recess 16 in the catch plate 7. The finger-piece may act on the spring through a lever with a cam surface, or through a sliding block with a cam surface. In another form, the detent is a plunger acted on by a helical spring.
