What specific features were present in the primitive wooden box camera patented in 1861?

Answer

A simple wooden construction, a lens, and a focusing screen made of ground glass

This early 1861 device functioned essentially as a portable camera obscura adapted for chemical photography. It lacked the modern conveniences of later mass-market cameras and required significant technical skill and specialized knowledge to operate and process images effectively.
