Figs. 10 and 11 are de segmental gear member, which may then be tail views of two keys to be used in conjunc rotated, that is, when further unlocking. tion with the lock for unlocking the same. Loosely journaled on the pin 23 behind Referring to the drawings, 1 designates a the dog is a gear 34, which meshes with the

4 ge teeth 9 of the segmental gear member. Loosely journaled on a pin 35 is a gear 36 meshing with the gear 34, so that as the gear 36 is rotated in one direction or the other the segmental gear member. will be actuated, so as to open or close the bolt 10. Secured at 37 in the recess 12 (the bottom of which is not quite as deep as the bottom of the pocket 5 from where the pins 23 and 35 pro 10 ject) is a bar 38 having a slot 39, through which the pin 35 extends. This bar 38 ex tends behind the gear 36 and the segmental gear member 8, and the free end of the bar 38 is provided with laterally extending lug 5 40, which engages a recess 41 on the inner face of the segmental gear member, thereby additionally locking the segmental gear member against being actuated. A spring 43, which is secured at 44 in the recess 13, 20 acts to press the bar:38 and the gear 36 out Wardly toward the cover plate, so as to hold the lugs 40 in the recess 41 of the segmental... gear member. The free end of the leaf - spring 43 has an elongated slot 45, through 25. which the pin 35 extends. The outer face of the gear 36 is provided with a slight re cess 46, which partially surrounds the pin 35, to receive the barrel 47 of the key 48, whereas the projecting wings 49 of the key 30 barrel enter the lateral recesses 50 of the gear 36, and when the key 48 is so arranged to engage the gear, and subsequently to pressing against the gear to disengage the lug 40 from the recess41 against the action 35 of the spring 43, the gear 36 may be rotated, which in turn will rotate the gear 34 and the segmental gear 8, that is, after the shoul der 18 has been moved from the path of the edge 25 of the segmental gear member. 40 When the segmental gear member is rotated in the direction of the arrow a, the bolt 10 is thrown open, and while being thrown open, the face (which is adjacent the cover plate) of the segmental gear member will 45 ride upon the enlarged portion of the dog, and the lug 40 will ride upon the opposite face of the gear member 8. When the seg mental gear member is thrown in a reverse direction the bolt 10 is moved to a closed 50. position, in which case the shoulder 18 and the lug 40 respectively of the dog and the bar 38 will spring into locked engagement with the segmental gear member automati cally The invention having been set forth, what is claimed as new and useful is: A padlock comprising a casing, a seg mental gear member having a semi-circular 60 bolt mounted in the casing for partial revo luble movement, a Spring retained dog hav ing an abutment shoulderlying in the path of the segmental gear member to lock the same against movement, and gear connec 65 tions adapted to be actuated by a member for partially rotating the segmental gear 1,153,405 member when the shoulder is thrown from its path to unlock the bolt. 2.
