A locking device is slidably mounted on the base for sliding movement to a locking position in a direction parallel to the plane of the door to engage the locking arm and hold the locking arm in the blocking position against the biasing when the door is closed, thereby locking the door. The door is unlocked by sliding movement of the locking device to an unlocking position in a direction opposite to the first mentioned direction to become disengaged from the locking arm, whereby the biasing returns the locking arm to the retracted position.

Abstract: The present invention is an improvement on an inner cylinder lock and more specifically, on the bolt thereof. The bolt engages an opening in the rear case of the inner cylinder lock. The improvement on the bolt prevents the bolt from moving in a lateral direction and restricts the travel of the bolt in a direction transverse to the lateral direction. This is accomplished by providing two generally rectangular projecting members, each of which extends from opposite sides of the bolt. The projecting members fit into accommodating channels which are disposed within the opening in the rear case. The bolt also has a cavity located in its rear. The purpose of the cavity is to receive a spring biased locking pin. The spring biased locking pin is located in the posterior wall of the rear case. During normal operation, the bolt is limited in its travel by a pin engages the bolt. The projecting members prevent lateral movement of the bolt.

Abstract: Apparatus for securing an emergency exit door includes a bolt for engaging a keeper, a dogging mechanism for dogging the bolt and a fluid throttling device disposed between the bolt and dogging mechanism. An electrical timer is connected to the dogging mechanism by a solenoid and starts to count upon an attempt to open the door. After a predetermined time interval has run, the electrical timer releases the dogging mechanism and allows the door to open. If the electrical timer fails to release the dogging mechanism, the door will still open if pushed due to operation of the fluid throttling device, which slowly shortens under pressure, allowing the bolt to clear the keeper.In order to readily align the keeper with the bolt, the keeper is loosely mounted and guided into alignment with the bolt by a bevelled guide. Upon being latched by the bolt, the keeper is held rigidly between the guide and the bolt.
