Abstract
1337784 Ratchet mechanism E L KNOWLES 6 Dec 1971 [20 Jan 1971] 2729/71 Heading F2Q A mechanism for advancing a drum 2 provided with internal teeth 3 comprises a member 1 pivotally mounted on a shaft 4 and having teeth 7, 8 adapted to engage the teeth 3. A spring 5 maintains the member 1 in the rest position shown in Fig. 2. On displacement of the member 1 by means of a push-rod 6, tooth 7 engages a tooth 3 to cause acceleration of the drum 2. Upon removal of the force applied to the pushrod 6, the spring 5 causes the member 1 to move back to its position of rest, the wheel 2 being slowed by impact of a tooth flank 10 with teeth 3. In a modification, the member 1 is provided with two teeth 12, Fig. 4a.
