Vintage Machinery entry for A. B. Farquhar Co., Ltd.
Description:
The firm of W. W. Dingee & Company made A. B. Farquhar a partner in the late 1850s. At about the time this patent was issued the Dingee factory was lost to fire and Farquhar ended up taking over the business which he renamed to the Pennsylvania Agricultural Works. That business incorporated in 1899 as A. B. Farquhar Co., Ltd.
