Alan H. Leamy – Patent Drawings

After the previous post covering Alan H. Leamy and his L-29 Cord patent drawing and the design renderings, we were curious to see if we could find any more of patents that he had applied for. Four more drawings were found, three of which are also of the L-29 and one of an Auburn sedan, that is dated as being granted on Nov. 10, 1931. This drawing appears to be of a 1931-32 Auburn.

Leamy who lived in Auburn, Indiana, at the time, stated in his patent application for the L-29 design the following: I have invented a new, original, and ornamental Design for an Automobile, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof. The figure is a perspective view of an automobile showing my new design. I claim:— The ornamental design for an automobile substantially as shown. Alan H. Leamy.


The Cord drawings are quite interesting especially the overhead view at the top, which shows not only his styling design work, but also the front suspension design very much like a FWD Miller racing car. The L-29 mechanical design was done by C. W. Ranst a former Miller engineer and racer, who was at the forefront of many new racing designs in the period of the late teens through the early thirties. Just below can be seen Leon Duray in his FWD Miller at Indianapolis and if you study the front end construction you can see just how similar they are. Check back to a post here on The Old Motor with more photos and information about about the famous racing driver Duray, including him setting a speed of 147 mph at the Packard Proving grounds with this fwd Miller in 1928.

Read Part I a very interesting related article by Pat Tobin about the the expermental V-12 Cord which was built and survives at the ACD Museum.

  1. David,

    Goossen and Miller designed the front drive for the race car and patented it in 1925. It was hard to shift while moving because the power went through the ring and pinion before the sliding gears. Not much of a problem for a race car driving 500 miles in top gear. Van Ranst knew this was no good for a road car and swapped the position of the gears and patented it in 1929. Duesenberg called Van Ranst a genius and hired him in 1916, and if you look closely at the 1920 Frontenac engine (a 38 degree VIA 47 years before Cosworth), he may have been.


    • All of these guys were unbelievable genius’s, thanks for clarifying that point, I was referring to C. W. Ranst’s work for Cord.

      Bugatti learned the same lesson about the hard shifting of the Miller design after buying a fwd Miller or two from Duray in
      France after a race there. The transmission was truly designed only for American style oval track racing.
