John H and August Hammes of Detroit

Classification: Query
I am trying to find information on John H. Hammes and August Hammes. They were officers in my Grandfather's company, Sewell Cushion Wheel of Detroit, MI.
There are a couple patents assigned to the company with John H. Hammes as inventor.
The Sewell company made wheels for fire rigs and service vehicles from about 1910 to 1929 in Detroit.
If anyone is interested I can give the patent numbers.
