Cornwall Brass and Iron Foundry.


scan0038Cornwall Brass and Iron Foundry, Boundary Road at Tenth Street East (formerly Track Road).


Denis E. Mahoney opened a foundry in Cornwall sometime around 1884, probably on the north side of 6th St. E. adjacent to his home.

Mahoney billed himself as a founder and a machinist and in 1889 produced threshing machines, circular and drag saws, horse hoses, cultivators, railroad horse powers, field rollers and plow point.

Mahoney claimed that the could repair “all kinds of machinery” and carried “all parts of Massey-Harris Company’s” parts “at the manufacturers prices.”



426 Pitt_Cwl Brass & Iron_1923The Cornwall Brass and Iron Foundry was in operation no later than 1923 at 426 Pitt Street, as seen in the above 1923 Fire Insurance Plan.

The 1916 version of the Fire Insurance Plan shows a stove foundry on that site (prior to the renumbering, 423 Pitt was 60 Pitt). The business name is not legible,

It’s unclear whether Cornwall Brass and Iron Foundry operated two locations simultaneously, or simply relocated from Pitt Street to 422 Sixth Street East in 1923.

The Sixth Street East site might have been the site of the old Mahoney Foundry under the managerment of John Thompson and P. Begin.  A decade later the business, now run by E.P. and J. Leroux listed their address as 422 6th St. E.

Throughout World War II they employed 4 to 5 people and paid out as much as $10,190 in wages and salaries.  Over the course of the War the value of their finished products rose from $8,720 to $15,800.  By 1944 Peter Leroux appears to have been the sole proprietor.

The Dec. 30, 1944 Progress Edition of the “Standard-Freeholder,” related that:

Working on the present time on war sub-contracts the firm makes brass and iron castings of all types.  Restrictions of raw materials have varied the types of unfinished brass and iron and expert workmanship is required to ensure that the level of quality maintained in former years continued throughout the war-time era.



Ad 1952. Is this a typo? The ad indicates that the business began in 1932, yet we know of its existence in 1923.


The foundry went out of business in 1976.  A year later the equipment was purchased by the newly opened Corbon Industries.

The archives at the Cornwall Community Museum contain hundreds of files relating to local businesses.
