Abstract

485,481. Latches. OLDHAM, J. L. Nov. 28, 1936, No. 32610. [Class 44] In a latch mechanism of the kind having a detent member which can engage a notch or projection 8 on a member 7 fixed on the spindle 4 so as to prevent operation of the latch, the detent member consists of a pivoted detent 11 and a strip spring 12 which is mounted on the same pivot 13 and carries the operating stud 16 and bears on the side of the detent to cause a pip 17 on the detent to enter a retaining recess 18. The stem 14 of the operating stud 16 ex tends through the de tent. The pivotal aper ture 20 of the detent is elongated to allow the tilting movement of the detent as the pip 17 rises out of the recesses 18. Movement of the handle is limited by the projection 8 engaging stops 9, 10.
