Abstract

This device is operable to couple a cam-like lever to a force-biased follower so as to prevent damage to a driven apparatus, in the event the force-biasing means fails to maintain the operative relationship between the lever and the follower.

Cam Follower Restraint Yoke

This device is operable to couple a cam-like lever to a force-biased follower so as to prevent damage to a driven apparatus, in the event the force-biasing means fails to maintain the operative relationship between the lever and the follower.

Drive lever or arm lO oscillates in an arc, back and forth as shown by arrow 11, as it is driven by an input force, not shown. Roller 12 and slide follower 13 are force biased in the direction identified by arrow 14, as by a cable and spring, not shown. Thus, follower 13 is positively displaced to the left, and energy is stored in the associated spring, when lever 10 moves to the left. When lever 10 returns to the right, the energy stored in the spring causes roller 12 to be maintained in contact with the lever 10.

If the spring or cable should fail, the apparatus which is carried by or driven by follower 13, not shown, could be damaged.

Yoke bracket 15, best shown in Fig. 2,'is pivotally attached to follower 13 and includes a slot 16 which cooperates with pin 17 carried by lever 10. The shape of slot 16 is designed to insure that the slot will ' not touch pin 17 during normal operation. However, the slot/pin arrangement will operate to limit the back and forth motion of follower 13 to a safe value, should the follower's force bias fail to operate properly.
