Delco Remy Division

Delco-Remy Patents

This page added 12-19-2019.

This page lists all of the Remy Brothers, The Remy Electric Company and Delco-Remy patents from the 1899 to 1989. Also ncluded in the list are patents from the Dayton Electrical Laboratories (Delco) from 1899 through 1929. This is because in 1926 General Motors combined the two divisions into Delco-Remy with its headquarters in Anderson, IN. With this consolidation the two sets of patents were combined into one listing. In 1929 the Dayton portion was split off by General Motors into the Delco Products Division of General Motors whose initial product line was shock absorbers. The Delco-Remy Division of General Motors kept the electrical related patents as it continued with that product line. Therefore, in the lists below there is a mixture of two companies' patents. Of note are patents not only by the Remy Brothers, but C.F. "Boss" Kettering of Delco.

Remy Electric Company Patents: 1899-1919

Delco-Remy Patents: 1970-1979
In this group is one of the most significant patents in Delco-Remy history, and the one that brought me to Delco-Remy. This is patent 4,129,107, dated 12-12-78, for a Magnetic Pickup Type Ignition Distributor, otherwise known as the High Energy Ignition, or HEI. I was hired in with other engineers in the early 1970s to help bring this product to market. My first job was as a tool room supervisor responsible for the wiring of electrical test equipment going into Plant 20. Without this invention and the subsequent work it brought to Anderson, I probably would have never been hired into the division. I would not have researched and published this history of the Delco-Remy Division of General Motors. DDJ
