- A 1925 concept drawing of the Ingemar K. Rystedt Car by C.C. Bratten.
Ingemar K. Rystedt of Dayton, Ohio was an automotive and aircraft inventor who held numerous patents, but like many, ninety-five years later, little is known of the man. He was born in Sweden and moved to Ohio by the late teens. The earliest reference found about him is in the April 19, 1919 Automobile Topics were it was announced that he and four others had incorporated the Wizard Spark Plug Co. in Dayton.
Rystedt’s first patent application to be found was filed on October 30, 1920 for a very imaginatively designed muffler for an airplane engine. The patent drawings show that the exhaust gases from the engine were ducted to a ring right behind the hub of the propellor. The gases next were to be drawn out by passages in the rotating propellor blade.
His next design to be found was for the Rystedt Super-Charger seen above-left in the December 1921 Automotive Trade Journal. This device as described in the article combined kerosene mist with the air-gasoline mix after it had gone through the carburetor. The device was of dubious merit and the ad claimed as countless others have to produce more power with less gas consumption.

The next endeavor that we found him connected with is the design of the Ingemar K. Rystedt Motor Car. The top photo in the post shows a colored artist rendering by C.C. Bratten, which like most drawings of this type lengthens and lowers the concept considerably from that seen in the April 22, 1925 patent drawing above. Nothing more is known about this car other than one-half interest in the design was assigned to Chester R. Synder, also of Dayton, Ohio.

The design post-dates some of the earliest streamlined cars known, those of Paul Jaray the Tropfenwagen of Edmond Rumpler and the North Lucas Car. The Rystedt Car stayed with the tried-and-true dirigible shape, but what it may have lacked in aerodynamic sophistication was more than made up in other ways by using a full pneumatic suspension labeled no. 8 in the drawings above and below.
The design also incorporated other interesting features for the time seen above that include: Wheels and tires set into the body work; Rystedt also designed fold-out steps that were mechanically actuated by a linkage attached to the door, and an interesting glass windshield even featured an opening panel for ventilation.
