The Miller-Chapman Security Auto-Theft Signal System, Patent 1,343,709








As a few of you know, I am in the process of finishing a book entitled Stealing Cars: Technology and Society form the Model T to Gran Torino. Recently I purchased what is described below on Ebay. The 1920s were one high point in stolen car activity, and there were numerous devices that were sold to deter thieves. The table below lists related patented equipment, and illustrates just how complex any history of technology can be.

The creation of Earle E. Chapman of Los Angeles, the "Vehicle Shackle" was one of numerous types of wheel and tire locks that  were patented during the 1910s and 1920s. Apparently there were 34 different sizes to accommodate a broad range of tire dimensions. The one I have is  marked B1.

  1. I came across your blog while trying to find info on the very same Miller-Chapman device you have pictured above. I was curious if you could tell me a ball park figure on it's worth/value or if you could point me in the direction where I could find out.
