RE-Isstra No. 8,550— Impkovbmbnts m Timb Locks— Novbltt. �Re-issued letters patent No. 8,550, for improvements in "time lockg," by which the multiple bolt-work of a safe or vault door could be automatically botli dogged or locked and unlocked at predeter- mined times,— the dogging and releasLng being caused by the opera- tion of the time mechanism, and the time for locking or unlocking being capable of alteration at the will of the operator, without dis- tnrbance of the clock-work, — contained, inter, alia, the following claims : �"(1) The combination of independent multiple bolt-work -with the time mechanism and locking or dogging mechanism of a time lock, automatically both dogging and releasing the bolt-work at predeter- mined times, substantially as described." �"(7) In a time lock the combination, substantially as aboye set forth, of the time movements and two adjustable devices, one for determining the time of locking and the other of unlocking." �Hdd, that the language of the seventh claim was not to be extended 80 as to include time ihovements which were usedfor any obstruct- ing purposes whatever, but was to be considered as referring to the time lock of the specification only. �2. Same— Same— Samb. �Hdd, therefore, that such claim was not anticipated by a patent for a structure containing two similar adjusting devices, which were operated to opcn and close a gas-cock much af ter the plan of the pat- ented lock. �3. Same— Invention. �Hdd, furihcr, that the changes necessary to transform old time locks which unlocked at predetermined times into structures which should also lock at predetermined times, required the exercise of inventive power. �4. Same— Samb. �Hdd, fitrther, that the application to siife doors of cbronometric mechanism for automatic locking and unlocking at predetermined times involved invention. 6. Samb— Infiungement. �Hdd, furtlier, that where a lOck has two adjustable devices for lock- ing and unlocking automatically at predetermined times, which are the equivalents of the mechanism of the patented lock, infringement is not avoided by the mere fact that the infringing lock can alao be used as an instant locker. ��� �
