The Pullman sash balance is a type of window balance system used to counterbalance the weight of a sash window. This system has been in use for over a century and is still commonly used today due to its effectiveness and reliability. In this article, we will explore the history and mechanics of the Pullman sash balance and its continued use in modern construction.
The Pullman sash balance was invented in the late 1800s by a man named George L. Pullman. Pullman was a well-known inventor and businessman who is best known for his creation of the Pullman Palace Car Company, which revolutionized train travel in the United States by introducing luxurious sleeping cars. However, Pullman was also an inventor and held several patents related to window and door hardware.
The Pullman sash balance was designed to provide a smooth and effortless operation for sash windows, which are windows that can be opened by sliding the bottom sash up or the top sash down. These windows are commonly found in older homes and buildings, but are still used in modern construction as well.
The Pullman sash balance works by using a coiled spring that is enclosed in a metal case. The spring is attached to the window frame and the sash, and when the sash is raised or lowered, the spring expands or contracts to counterbalance the weight of the sash. This allows the window to be opened and closed with ease, and prevents the sash from slamming shut or falling open.
One of the key benefits of the Pullman sash balance is its durability. The system is designed to last for many years without needing to be replaced or repaired. This is in part due to the fact that the spring is enclosed in a metal case, which protects it from dust, dirt, and other debris that can cause wear and tear. Additionally, the system is designed to withstand the weight of heavy sashes, making it ideal for use in larger windows.
Another benefit of the Pullman sash balance is its versatility. The system can be used in a variety of different types of sash windows, including single hung, double hung, and triple hung windows. This makes it a popular choice among architects and builders who need a reliable and effective window balance system for a wide range of projects.
Despite its many benefits, the Pullman sash balance is not without its drawbacks. One potential issue with this system is that it can be difficult to install and adjust. Because the spring is enclosed in a metal case, it can be tricky to get the tension just right, and adjustments may need to be made over time as the window and the balance system settle in. Additionally, because the system is designed to last for many years, it can be difficult to replace if it does fail or break down.
Regardless of these potential drawbacks, the Pullman sash balance remains a popular choice for window balance systems due to its many benefits. Its durability and versatility make it an ideal choice for a wide range of projects, and its smooth and effortless operation ensures that windows can be opened and closed with ease. While there are other window balance systems available, the Pullman sash balance has stood the test of time and remains a reliable and effective choice for modern construction.
In conclusion, the Pullman sash balance is a window balance system that has been in use for over a century. It was invented by George L. Pullman and is designed to provide a smooth and effortless operation for sash windows. While it can be difficult to install and adjust, its durability and versatility make it a popular choice for architects and builders who need a reliable and effective window balance system. If you are considering installing sash windows in your home or building, the Pullman sash balance is definitely worth considering as an option. Still have questions about Pullman sash balances?
