Cast Iron Furnace Draft Damper Face Plate | Original Chain Intact | Cincinnati, Ohio
c. 1895–1911 • The Peck-Williamson Co. • Cincinnati, Hamilton County, Ohio • Ohio Foundry Corridor
The Peck-Williamson Co. furnace damper control face plate, front face. Cast iron, semicircular arched form with flat base. The raised lettering reads THE PECK-WILLIAMSON / CO. / FURNACES / CINCINNATI. in bold block capitals arranged across the face. The circular draft control disc is cast in the arch at center — the rotating damper mechanism that regulated the coal fire’s air supply and therefore the heat output of the furnace. Original chain hangs from two mounting holes at the base corners — the chain that connected the damper disc to the control rod inside the furnace firebox. SSC-PW-FRN-DMP-001. Cincinnati, Hamilton County, Ohio.
In the basement of nearly every American home of any consequence between 1890 and 1920, there was a furnace. Not the sleek forced-air units of the mid-20th century, not the gas-fired boxes of the modern era, but an enormous cast iron apparatus — a gravity hot-air furnace that consumed coal, radiated heat through ductwork by convection alone, and required daily tending by whoever lived in the house. The furnace was the center of domestic thermal life. Managing it meant managing the damper — the disc that regulated airflow to the fire, and therefore the fire’s intensity, and therefore the warmth of every room above.
The Peck-Williamson Co. of Cincinnati, Ohio made furnaces — and they put their name, their city, and their product on a cast iron plate that mounted on the face of the damper assembly. This is that plate. THE PECK-WILLIAMSON / CO. / FURNACES / CINCINNATI. Four lines cast in raised block capitals on a semicircular iron panel, with the draft control disc at the top of the arch and the original chain still hanging from the two mounting holes at the base corners. Every homeowner who had a Peck-Williamson furnace in their basement saw this plate every time they went to tend the fire. It was the company’s permanent identification — cast in iron and meant to last as long as the furnace itself.
The SSC Museum Collection documents Ohio’s industrial cast iron heritage across its full range — from hollow ware and cookware to architectural and industrial castings. The Peck-Williamson furnace plate is one of the most distinctly domestic industrial pieces in the collection. It is not cookware. It is not a tool. It is the face of the machine that heated American homes during the coal furnace era, and it carries the name of one of Cincinnati’s most significant heating equipment manufacturers, cast in the same iron tradition that produced Ohio’s stoves, kettles, and hollowware.
The Plate: Form, Function, and the Original Chain
Reverse face of the Peck-Williamson damper control plate, showing the plain cast iron back, the center through-bolt hole, and the two corner chain mounting holes through which the original chain passes. The chain connected the rotating damper disc on the front face to the control linkage inside the furnace — pulling the chain adjusted the disc position, opening or closing the draft to regulate the fire. The back is undecorated functional iron — the reverse of a face plate meant to be seen from the front only.
The plate is a semicircular arched casting with a flat base — approximately 6 to 7 inches across the base, consistent with other documented Peck-Williamson damper plates from the same era. The arch contains the circular draft control disc: a cast iron ring mounted in the arch that could be rotated to open or close the air passage behind it. Draft control was the fundamental act of furnace management — more air meant more combustion, more heat, more coal consumed; less air meant a slower burn, lower temperatures, coal conservation. The homeowner or the furnace tender adjusted the damper by hand, reading the conditions of the fire and the temperature of the house, turning the disc accordingly.
The chain is original and intact — a fine link chain attached through the two corner holes at the base of the plate, hanging in a shallow arc beneath the casting. This chain connected the face plate’s damper mechanism to the control rod or lever inside the furnace firebox. In practice, the chain was the interface between the homeowner and the fire: you pulled the chain to adjust the draft, you felt the resistance that told you the damper was moving, you released it when the position was right. The chain is not decorative. It is the functional connection between a person and their heat source, and the fact that it survives intact after more than a century adds a dimension to this piece that a bare plate would not have.
The reverse face is plain cast iron — no markings, no decoration, no manufacturer identification. The back was the mounting surface, hidden against the furnace body. The single center through-bolt hole anchored the plate to the furnace. The two corner holes are the chain passes. Everything on the back is functional and nothing else. The contrast between the elaborately marked front face and the completely plain back tells you exactly what this object was: a public-facing identification piece on an otherwise anonymous industrial appliance.
The Peck-Williamson Co.: Cincinnati’s Furnace Makers
The Peck-Williamson Co. of Cincinnati, Ohio was one of the most significant furnace manufacturers in the American Midwest during the late 19th and early 20th centuries. Their corporate history traces a clear line through Cincinnati’s heating equipment industry from the post-Civil War era through the consolidation period of 1911.
The company began in 1882 as the Bennett Furnace Company, founded in Cincinnati by individuals whose names would evolve through successive partnerships into the Peck-Williamson identity. Around 1890, the firm reorganized as the Bennett & Peck Company, absorbing a new partnership structure that brought the Peck name into the corporate identity. By approximately 1890 to 1895, the company had reorganized again under the name Peck-Williamson Heating and Ventilating Company — the name that appears in trade publications including The Metal Worker as early as October 5, 1895, and in national advertising in The Saturday Evening Post by January 14, 1905, Popular Mechanics in 1908, and The Century Illustrated Monthly Magazine as late as July 1911.
The Peck-Williamson name was in active commercial use from approximately 1890 through 1911. During that period the company produced and marketed gravity hot-air furnaces for residential and commercial heating — specifically including the “Underfeed Furnace” that appears prominently in their 1905, 1906, and 1908 advertising. The Underfeed design was a specific Peck-Williamson innovation in which coal was fed from below the fire rather than from above, allowing more efficient and even combustion. National advertising campaigns for this product ran in major publications, making Peck-Williamson one of the most visible Cincinnati manufacturers of its era.
In 1911, Peck-Williamson acquired several other heating equipment businesses and reorganized as the Williamson Heater Company — the Peck name dropping from the corporate identity as the company scaled into a larger operation. The Williamson Heater Company continued as a Cincinnati institution, manufacturing furnaces and boilers for decades, eventually becoming The Williamson Company and operating at its Cincinnati plant on Ridge Road at Madison until the company’s assets were acquired by Metzger Machine Corporation of Milwaukee in 1992. In 1999, the Williamson brand was acquired again and became part of Williamson-Thermoflo, which continues to manufacture cast iron boilers today under the parent company WM Technologies, LLC.
The damper plate in the SSC collection was produced during the Peck-Williamson Co. period — after the Bennett & Peck reorganization brought the Williamson name into the firm, and before the 1911 reorganization dropped the Peck name. The marking THE PECK-WILLIAMSON / CO. / FURNACES / CINCINNATI. is precisely consistent with the corporate identity used from c. 1890–1895 through 1911. The plate is therefore a documented artifact of the Peck-Williamson era — the most significant period in the company’s history, when their Underfeed Furnace was being marketed nationally and the company was at its peak commercial presence.
The Coal Furnace Era: What This Plate Meant in an American Home
To understand what the Peck-Williamson damper plate is, you have to understand the world it was made for. In 1900, central heating in an American house meant a coal furnace in the basement. Not gas, not oil, not electricity — coal. The furnace was a large cast iron apparatus that burned bituminous or anthracite coal to heat air, which rose by convection through ductwork to registers in the floors and walls of the rooms above. The homeowner or a servant maintained the fire: loading coal, managing ash, and critically, controlling the draft through the damper.
The damper was the primary control mechanism of the coal furnace. Gravity hot-air furnaces of the Peck-Williamson era had no thermostat, no automatic controls, no electronic regulation. Heat output was managed entirely by the human operator adjusting the air supply to the fire. Open the damper fully and the fire burned hot and fast, consuming coal rapidly and generating maximum heat. Close it down and the fire slowed, the heat output dropped, the coal lasted longer. Bank it nearly shut overnight and the fire smoldered through the night, ready to be opened again in the morning. The damper control plate was the interface between the homeowner and all of this — the visible, touchable, chained mechanism through which a family regulated their comfort through a Cincinnati winter.
The Federal Furnace League, formed in 1905 specifically to address quality and rating standards in the warm-air heating industry, was operating in exactly the Peck-Williamson era. The industry was competitive to the point of destructive price wars, and national advertising campaigns — like the ones Peck-Williamson ran in The Saturday Evening Post and Popular Mechanics — were how companies differentiated their products. The Underfeed Furnace was Peck-Williamson’s technical selling point. The cast iron damper plate with the company’s name in raised block letters was their permanent identification on every unit they sold.

Why This Piece Matters
The Peck-Williamson furnace damper plate is not a piece of cookware. It is not a skillet, a kettle, or a hollow ware form. It is a furnace component — a functional cast iron object from the domestic infrastructure of the American coal heating era, produced by one of Cincinnati’s most significant heating equipment manufacturers during the most active period of that company’s national commercial presence.
The SSC collection documents Ohio’s cast iron heritage across its full range, and the Peck-Williamson plate extends that mandate into the domain of domestic industrial castings. Ohio was not just a producer of cookware and hollow ware — it was a center of the American heating equipment industry, and Cincinnati specifically was home to manufacturers whose products heated homes across the country. Peck-Williamson ran national campaigns in The Saturday Evening Post and Popular Mechanics. Their Underfeed Furnace was a documented innovation. Their corporate lineage runs unbroken from 1882 to the Williamson-Thermoflo brand that still manufactures cast iron boilers today.
The original chain makes this piece exceptional. Most surviving Peck-Williamson damper plates have lost their chain hardware over the century-plus since the furnaces they were mounted on were torn out and scrapped. The chain on this piece is intact, original, and functional — the same chain that once connected a Cincinnati homeowner’s hand to their furnace fire. That continuity is the kind of detail that transforms a marked cast iron component into a document of how American families actually lived in the coal furnace era.

About Steve's Seasoned Classics
Steve’s Seasoned Classics is an online museum dedicated to preserving and documenting the heritage of American cast iron, with a singular focus on the obscure, defunct foundries of Ohio from the 19th and early 20th centuries. The SSC collection spans 130+ pieces from 50+ confirmed Ohio makers — the majority absent from standard collector references. Makers were identified through physical artifacts exhibiting gate marks, patent dates, foundry traits, and documented regional provenance, cross-checked against surviving trade directories, census records, and existing collector guides. Makers lacking representation in published guides but supported by physical evidence were flagged for first-time documentation — a core function of the SSC research mission.
