Description:

"This invention relates to dynamo electric machines and more particularly to provisions for dissipating the heat in such machines by the introduction of cooling air."

This patent was subsequently improved in a patent, 1,679,457, that was assigned to H. C. Dodge, Inc. of Boston. Mr. H. C. Dodge was the president of woodworking machinery maker S. A. Woods Machine Co., and H. C. Dodge, Inc., was bought out by S. A. Woods Machine Co., and therefore this patent was used on motors for woodworking machinery. Patent 1,805,437 was co-invented by John B. Wiard and assigned to S. A. Woods Machine Co.
