Tillinghast Machine Shop
One of McDonald's first and longest enduring local industries. The shop was established in 1892 and operated through the late 1940s by Mr. B. D. Tillinghast, a highly acclaimed mechanical engineer and inventor. The shop focused on manufacturing quality mechanical equipment such as pumps, steam engines and compressors for use by the booming oil, gas and coal industries. As those industries grew across the nation and the world, so did the Tillinghast engineering shop's reputation and business.
Over the years the Tillinghast Machine Shop was located in two different locations in McDonald Borough The first shop was on the East side of North McDonald Street, near Washington Avenue A second and much larger, location was built in 1910 near the Southwestern corner of South McDonald Street and Johns Avenue, about two blocks from the train station.
Much information regarding Tillinghast engines, pumps and other equipment can still be found today on the internet.
McCarty Lumber Yard
For over 65 years the McCarty lumber yard, located at the corner of S. McDonald St. and Johns Ave., across the street from your current location, was the main source of quality building materials for the McDonald area.
In 1895, J. S. McCarty and J. W. Robb, both Washington County natives, formed a partnership and purchased two small lumber yards In McDonald owned by William George and M. O'Donnell respectively. The "McCarty and Robb Lumber and Builder Supplies Co." business soon flourished and expanded as McDonald entered into its growth boom during the late 1890s and early 1900s.
In 1905 Mr. Robb sold his interests to Mr. McCarty. Mr. McCarty continued in the business and eventually brought his two sons, J. Kerr and Robert McCarty into the business as partners in "McCarty Lumber Co."
Following the death of J. S. McCarty in 1918 his eldest son, J. Kerr McCarty, became the primary owner and President of McCarty Lumber Co. and remained so until his death in 1943...McCarty Lumber Co. changed ownership in the late 1940s but remained in operation under that name until the early 1960s when the yard was closed and the original buildings torn down.
Note the Pennsylvania Railroad side tracks that were used to deliver lumber and other building materials and the horses and wagons used to conduct local business.
