Abstract

648,555. Locking rotary elements. PHILIPS ELECTRICAL, Ltd. Sept. 10, 1948, No. 23822. Convention date, Sept. 13, 1947. '[Class 80(iv)] A ratchet wheel 1 with teeth 2 is adapted to be positively held against rotation in one, direction by a detent pawl 7 which is pivoted about a pin 8 and carries a roller- 4 engaging between it and the teeth 2. The roller 4 on movement of the pawl 7 to engage or disengage has a rolling action on both the tooth surface and a surface 6 of the pawl 7 and is retained in position on the pawl by a spring 9. In a modification both sides of the teeth 2 are square so that a positive locking in both directions is obtained.
