An instrument developed by the Ashkir-Jobson Trianion Guild to help record supposed messages from the dead. The guild was founded by two British researchers, A. J. Ashdown and B. K. Kirby after the death of their colleague, George Jobson. Prior to Jobson’s death, the three had made a compact that the first to die would attempt to communicate with the other two. Ashdown and Kirby believed that such a contract had been established through a medium previously unknown to them, Mrs. L. E. Singleton. She not only gave them the agreed-on message, but through her, Jobson offered instructions for several communication devices, including the reflectograph.
The reflectograph consisted of a large typewriter that was modified in such a way that its keys were very sensitive to the slightest pressure. Even a slight depression would close a circuit and light up a corresponding letter on a letter board. It was situated just outside of the medium’s cabinet. Once she went into trance, one of her hands would reach outside the cabinet and type out any messages.
