Wooden and steel patent model from 1852 showing a prototype spark arrestor system to be mounted on top of a steam locomotive and passenger train. This system would have acted as an exhaust pipe directing the sparks generated by the train out the stack and exiting directly behind the train. There is a plaque attached to the model which reads, " Railroad Smoke & Spark Conductor Invented by Peter C. Guiou August 11, 1852 Cincinnati, Ohio" The model measures 26 1/2" long, 3" wide, and 6 1/4" tall. The model is in generally good condition with the exception of a number of the wooden wheel flanges have broken over the years. There is a second paper tag tacked to the side of the model which has faded but appears to read, "Spark Conductor August 11, 1852" This model showcases a unique idea and presents it in a way that is engaging and enjoyable to look at. Per our consignor, this item was once a part of the company archives of the New Haven Railroad.
