This is a piece in the annals of engineering history. Developed by George Frick in the late 19th century, the Frick steam engine was renowned for its precision craftsmanship. The 10 HP Eclipse model shown here is capable of turning out 5000 feet of lumber a day, 2,400 chairs annually, or four bushels of wheat AN HOUR! 

 Every component was meticulously designed and manufactured to exacting standards, ensuring smooth and reliable operation. The frame or bed which comprises the cylinder head, the guides for the crosshead, and the two bearings for the crankshafts are also cast solid; so that it is impossible for the important working parts to get out of line.

Here is our steam mockingbird whistle. The technical term for this rare item is a variable pitch whistle. Steam is injected into the whistle at the small ball valve. The variable pitch is controlled by the vertical stem at the base of the whistle. The operator could change the pitch of the whistle by raising or lowering the rod. 

While our whistle is more modern than this type of whistle’s patent from September 1872, the inventor’s design intention is clear: 

“This invention consists in so constructing a steam-whistle that a movable piston within the cup or cylinder above the steam-orifice modulates the sound of the whistle to a scale of tones, or higher or lower notes. The piston is managed from any distance below by means of a rod at the pleasure of the operator, and where a scale of notes may be placed, by which, and by moving the rod, a tune may be played.” 

The Interstate Machine Co. was founded in New London, Connecticut and later transferred their headquarters to Rochester, New York.  The Interstate Machine Co. is most well-known for its early 20th century Sterling Siren Fire Horns. In researching the company’s background, we discovered Interstate also offered lubricators and oil pumps. 

This is our one horsepower steam engine from the Interstate Machine Co. The previous owner of this beauty took great care in maintaining the engine in fine working condition. The lubricating points still have packing in them, and the engine rotates smoothly. We are proud to have this Interstate Machine Co. engine on display.

This is our Lunkenheimer Banner #6 Oiler. The Lunkenheimer Company was founded in Cincinnati, Ohio in 1862 by Frederick Lunkenheimer; its original name was Cincinnati Brass Works. In 1893 it was renamed the Lunkenheimer Valve Company after the founder’s son, Edmund, became involved. The Lunken Airport in Cincinnati, Ohio is named for the family after they donated land to the city in 1927 which previously was their private flying field. 

The oiler is designed to be used with both gas and steam engines. Proper lubrication was essential for the efficient and long-lasting operation of these engines, preventing wear and tear. Our oiler can hold two pints of lubricating oil. It operated by allowing oil to drip into the engine at a controlled rate. The vent helped maintain a steady flow by preventing air from becoming trapped inside the oiler.

Amongst the many smaller items PMI proudly displays in our steam museum, we have several exciting small steam toys.  This week we’re highlighting an alcohol burning steam boiler from a well-known toy manufacturer, Gebrüder Bing, or Bing Brothers. Founded in 1865 in Nuremberg, Germany, the Bing Brothers focused on tableware until the 1880s when they shifted to toy manufacturing. They’re most famous for their trains and steam engines.  

The Bing Brothers’ toys were popular around the world with their sales in the United States outpacing that of U.S. based manufacturers.  However, with the onset of World War I, exports ceased. The company recovered slightly post war, but ultimately shuttered in 1933; and the Bings emigrated from Germany to escape rising antisemitism. 

Our steam toy’s logo suggests it was manufactured somewhere between 1906 and 1920 according to several toy historians.

The steam calliope was invented in the mid-19th century by Joshua C. Stoddard and quickly became one of the most recognizable musical instruments of the steam age. Commonly heard at circuses, carnivals, fairs, and riverboats, the calliope used steam power to produce its distinctive high-pitched sound that could carry for great distances.

The instrument consists of a series of whistles or pipes, each tuned to a different musical note. When the performer presses the piano-style keys, steam or compressed air is directed through the pipes, creating the bright and often whimsical tones associated with the instrument. Because of its expressive and melodic sound, the calliope was named after Calliope, the Greek muse of eloquence and epic poetry.

The calliope displayed in the Power Mechanical Steam Museum is powered by an attached boiler system that generates the steam required to operate the instrument. Restored in 2004, the boiler features a heating surface of 57 square feet and a maximum steam capacity of approximately 285 pounds per hour. Together, the instrument and boiler demonstrate the creative ways steam technology was used not only for industry and transportation, but also for entertainment during the height of the steam era.

A steam car is a steam automobile propelled by an external combustion steam engine. The first steam cars were built in the 18th and 19th centuries, although this is from the 1900s. A car like this can take 30 minutes to startup and it has been fired up by our employees for the first time in what may have been many years. Come visit our facility and take a tour around the campus in our steam car.

A replica 1899 Locomobile Runabout was recently rebuilt and fired up by Power Mechanical’s machinists and steam experts. This Locomobile will be featured in Power Mechanical’s Steam Museum.  Steam-powered automobiles’ origins date back to the 18^thcentury. Richard Trevithick is credited with engineering the ability to harness high pressure steam in 1800, facilitating the commercial development of steam-powered engines. Leading the way in steam technology starts with honoring its foundations.

Orr & Sembower was founded in 1885 in Reading, PA and later opened offices in NYC, Chicago, and Boston. This vertical steam boiler likely was coupled with a vertical steam engine which turned that steam energy into mechanical horsepower. An excerpt from Orr & Sembower’s 1900 trade magazine publication depicts a visual example.  The two vertically aligned holes to the right of the handhold are for the sight glass.  This boiler’s fuel source was wood or coal.

In the Steam Museum, we showcase the engine block from a 1906 White, Model O steam car. By many accounts, White steam cars were some of the finest engineered steam vehicles of that generation. The company got its start manufacturing sewing machines when Thomas H. White formed the White Sewing Machine Company with a few business partners. The business was a great success and Thomas was able to send his son, Rollin, to Europe to receive training in steam automobile manufacturing. 

Rollin H. White patented a highly efficient steam generator in 1900, and the White Sewing Machine Company began manufacturing steam cars the same year. In 1906, the automobile manufacturing division was established as its own company, the White Motor Company. Our two-chamber steam engine was connected to Rollin White’s invention, converting steam energy into mechanical power, achieving around 20 HP. 

The portable forge was an essential tool of the blacksmith’s trade during the late nineteenth and early twentieth centuries. Designed for mobility and practicality, these compact forges allowed craftsmen to bring their work directly to farms, construction sites, railroads, and remote workshops where metal repairs or fabrication were required.

Each portable forge was equipped with a coal-fired firepot and a hand-cranked blower that supplied controlled airflow to the fire. By increasing or decreasing the airflow, the blacksmith could regulate the temperature of the coals and achieve the intense heat necessary to shape and forge iron and steel.

Though small in size, the portable forge provided the same fundamental capability as a full blacksmith shop. Its rugged construction and simple mechanical design made it reliable in the field and indispensable for tradesmen who needed to repair equipment or fabricate parts wherever the work demanded.

Today, the portable forge stands as a reminder of the ingenuity and craftsmanship that powered the industrial and agricultural growth of its era.

Ever wonder where the phrase “balls-out” comes from? Believe it or not, it has steam-powered roots.

At the Power Mechanical Steam Museum, we proudly showcase several original steam governors—ingenious devices once used to regulate the speed of steam engines and locomotives. As the engine accelerated, the weighted balls on the governor spun faster and moved farther from the center due to centrifugal force. When those balls reached their maximum distance, the engine was running at full throttle—what engineers referred to as “balls-out.”

It’s a clever piece of engineering that not only helped control powerful steam machinery, but also left its mark on everyday language. Discovering connections like this reminds us how much steam technology shaped both industry and the words we still use today.

The Arla Kay began its life in 1957 as a Navy lifeboat assigned to the USS Providence. Built for reliability and durability, vessels like this were designed to safely transport sailors during emergencies and operations at sea. Though originally powered differently during its naval service, the boat has since been carefully restored and converted into a fully functioning steam-powered launch.

Today, the Arla Kay operates using traditional steam technology, demonstrating the same principles that powered countless vessels during the height of the steam era. The boiler is typically fired using hardwood, though it can also run on coal, preserving the manual operation and hands-on engineering that defined steam propulsion. Steam generated in the boiler powers the engine, which converts that energy into mechanical motion to drive the boat’s propeller.

The vessel’s journey to the Power Mechanical Steam Museum is part of its unique story. After years away from the water, the Arla Kay was transported from Arkansas to Virginia, where it was restored and returned to operation. Today it serves as both a working example of steam-powered marine technology and a living demonstration of the engineering practices that once powered transportation across rivers, lakes, and oceans.

Now part of the Power Mechanical Steam Museum collection, the Arla Kay continues to operate and make appearances on local waterways. It stands as a reminder of the versatility of steam power and the craftsmanship required to keep these historic machines running well into the modern era.

Steam traction engines were some of the earliest self-propelled machines used in agriculture and industry. Developed in the late nineteenth century, these powerful engines combined a steam boiler and mechanical drivetrain on a wheeled chassis, allowing them to move from location to location while providing reliable mechanical power.

Fuel such as coal or wood was burned in the firebox to heat water inside the boiler, creating pressurized steam. This steam powered a piston-driven engine that turned large gears connected to the drive wheels. In addition to moving the machine itself, traction engines were often used to operate belt-driven equipment such as sawmills, threshing machines, grain elevators, and water pumps.

Before the widespread adoption of gasoline and diesel tractors, traction engines were essential tools for large farms and industrial operations. Their ability to provide both mobility and mechanical power made them one of the most important working machines of the steam era.

Today, preserved traction engines serve as impressive reminders of the ingenuity and engineering that powered agriculture and industry during the height of steam technology.

The Steam Museum displays several historic steam whistles—devices that once served as the voice of the steam-powered world. Throughout the late nineteenth and early twentieth centuries, steam whistles were widely used on railroads, factories, mills, and steam-powered vessels. A steam whistle operates by directing pressurized steam through a specially shaped chamber, producing a loud tone that could be heard over great distances.

Steam whistles played a vital role in industrial communication. They signaled train departures, marked factory shift changes, warned workers of emergencies, and alerted towns of approaching locomotives. Long before modern communication systems existed, these powerful sound signals helped coordinate operations and improve safety across large industrial sites.

This wood planer was manufactured in the early 1900s by the Crescent Machine Company of Leetonia, Ohio. Crescent was well known for producing high-quality woodworking and metalworking machinery that supported industries such as furniture manufacturing, cabinetry, and flooring. Machines like this planer played a critical role in shaping and finishing lumber used in homes, furniture, and construction projects.

Wood planers were designed to produce boards with consistent thickness and smooth surfaces by shaving thin layers from the wood as it passed through the machine. While this particular model was likely powered by an early electric motor, it operates on the same mechanical principles as earlier planers that were driven by belts connected to steam-powered engines in large workshops and mills. This planer represents the evolution of industrial woodworking technology during the transition from steam power to electricity.

Founded in 1904, the Armstrong-Blum Manufacturing Company quickly became known for developing innovative and reliable cutting equipment for industrial workshops. One of the company’s notable designs was the No. 1 Rapid Cut Saw, patented in 1912 by George J. Blum. Built during a time when steam power was still widely used in factories, this saw represents the transition period between steam-driven machinery and the rise of electric-powered tools.

The Rapid Cut Saw used steam-powered mechanical motion transmitted through a pulley and flywheel system to drive the cutting blade. This design allowed workshops to achieve efficient, consistent cutting performance long before electric motors became standard in industrial environments. The example displayed in the Power Mechanical Steam Museum has been fitted with a modern blade, allowing visitors to see how this early twentieth-century engineering design can still function today—demonstrating the durability and ingenuity of steam-era machinery.

This steam injector represents an important advancement in boiler technology during the late 19th century. The design is based on improvements patented in 1890 by Parker R. Hogue of Pennsylvania, building upon the original injector concept developed by French engineer Henri Giffard in 1858.

Steam injectors provided an innovative way to feed water into boilers without the need for mechanical pumps. By using steam from the boiler itself, the injector accelerated water through specially designed nozzles, creating enough pressure to force the water back into the boiler system.

As steam engines and industrial boilers increased in size and operating pressure, improved injector designs like Hogue’s allowed systems to operate more reliably and efficiently. These devices became essential components in locomotives, factories, and other steam-powered operations throughout the late 19th and early 20th centuries.

Today, this injector stands as an example of the ingenuity that helped drive the expansion of steam technology during the Industrial Revolution.

This hot air engine was manufactured around 1890 by Heinrici of Zwickau, Germany, a company well known for producing precision scientific and measuring instruments. In addition to these instruments, Heinrici developed compact hot air engines designed to power specialized equipment, including dental drills.

Hot air engines operate using the expansion and contraction of heated air. As air inside the engine is heated, it expands and creates pressure that drives pistons within the machine. This motion converts thermal energy into mechanical movement, allowing the engine to power small tools.

In dental practices of the late 19th century, these engines provided a dependable source of power for drills before electricity became widely available in medical offices. Their smooth and consistent operation helped dentists perform more precise procedures compared to earlier manually powered tools.

Today, this Heinrici dental engine illustrates how inventive mechanical engineering influenced not only industry, but also the development of modern medical and dental practices.
