Which part of the sidelock are you referring to? Most parts will have no patent as they originate at the dawn of time.
The 'spear' interceptor sear was never patented as Boss used it in most of his actions although a similar hook system does appear in his early patent 2833 of 1882.
The usual cocking lever is not covered by any of his patent and is basically a Roger's patent.
The ejectors are usually a variant on any of his 3 patents with Holland 5834 & 11623 of 1887 or 16691 of 1888.
Later he used his own ejector patent 2988 of 1897.
