The brush manufacturing business which ultimately became Pilley Industries originated prior to 1889 in St. Louis, Missouri under the name of the American Manufacturing Company owned by Mr. L.B. Shultz. On the 22nd day of July 1889, the Shultz-Miller Manufacturing Company was incorporated under the laws of the State of Missouri and was authorized to purchase the business then being conducted by L.B. Shultz. Mr. E.M. Miller was elected President of the new company.

In early 1940, during the modernization of the St. Louis riverfront and the establishment of the Jefferson Memorial, the manufacturing facility of the Pilley Brush Company became a part of the program and it became necessary for them to relocate.

The Missouri corporation was dissolved and the company was incorporated in the State of Iowa on May 29, 1941.

On Monday May 9, 1966, the old brick building housing Pilley Brush Company was destroyed by a fire. Crandon Paper Mill, who owned the old Sinclair buildings allowed Pilley Brush to temporarily relocate within the Sinclair building until Pilley could construct the new building. The new building was constructed on the same location as the old building.
