The Stanley plane is an iconic tool in the world of woodworking, with a history that spans over a century. One of the most fascinating aspects of Stanley planes is the ability to date them, which can provide valuable insights into their history, value, and authenticity. In this article, we will explore 5 ways to date a Stanley plane, including the use of patent dates, type studies, blade markings, adjustment mechanisms, and manufacturing codes.
Key Points
- Patient dates can be used to narrow down the manufacturing period of a Stanley plane
- Type studies involve analyzing the physical characteristics of a plane to determine its age
- Blade markings, such as the presence of a "Stanley" logo, can indicate the plane's manufacturing period
- Adjustment mechanisms, like the type of frog adjustment, can be used to date a plane
- Manufacturing codes, such as the "SW" code, can provide specific information about a plane's production date
Understanding Patent Dates
One of the most straightforward ways to date a Stanley plane is by looking at the patent dates stamped on the plane. Stanley was a prolific innovator, and many of their planes feature patent dates that correspond to specific improvements or designs. For example, the patented “Bailey” plane, which features a unique adjustment mechanism, was patented in 1858. By checking the patent dates on a plane, collectors and enthusiasts can narrow down the manufacturing period to a specific range of years.
Early Patent Dates (1850s-1880s)
Dating a Stanley plane from the early patent period requires careful examination of the plane’s features and markings. During this period, Stanley planes often featured simple, minimalist designs, with few adjustable parts. The presence of a patent date from this period, such as the 1858 Bailey patent, can indicate that the plane is an early model. However, it’s essential to note that Stanley often used earlier patent dates on later planes, so this method is not always foolproof.
Type Studies: Analyzing Physical Characteristics
Type studies involve analyzing the physical characteristics of a Stanley plane to determine its age. This method requires a deep understanding of Stanley’s design evolution and manufacturing practices. By examining the plane’s shape, size, and features, such as the type of handle or adjustment mechanism, collectors can narrow down the plane’s age to a specific range of years. For example, the introduction of the “Bedrock” plane in the early 20th century featured a distinctive design with a raised bed and adjustable frog, which can be used to date planes from this period.
Evolution of the Stanley Plane Design
Stanley’s plane design evolved significantly over the years, with various models featuring distinct characteristics. The “Bailey” plane, for example, featured a unique adjustment mechanism, while the “Bedrock” plane had a raised bed and adjustable frog. By studying these design changes, collectors can gain a deeper understanding of the plane’s age and manufacturing period.
| Plane Type | Manufacturing Period |
|---|---|
| Bailey Plane | 1858-1880s |
| Bedrock Plane | Early 20th century |
| Stanley No. 5 Plane | Late 19th century-early 20th century |
Blade Markings and Adjustment Mechanisms
Blade markings and adjustment mechanisms can also be used to date a Stanley plane. The presence of a “Stanley” logo or other markings on the blade can indicate the plane’s manufacturing period. Additionally, the type of adjustment mechanism, such as the frog adjustment, can provide clues about the plane’s age. For example, early Stanley planes often featured a simple, non-adjustable frog, while later models had more complex adjustment mechanisms.
Manufacturing Codes and Date Stamps
Some Stanley planes feature manufacturing codes or date stamps that can provide specific information about the plane’s production date. The “SW” code, for example, indicates that the plane was manufactured during the Stanley Works era, which spanned from 1843 to 1920. By decoding these manufacturing codes, collectors can gain a more precise understanding of the plane’s age and manufacturing history.
How can I determine the age of my Stanley plane?
+To determine the age of your Stanley plane, examine the patent dates, type study the physical characteristics, check the blade markings, and look for manufacturing codes or date stamps. You can also consult with a collector or expert to gain a more precise understanding of your plane's age and value.
What is the significance of the "Bailey" plane patent date?
+The "Bailey" plane patent date of 1858 corresponds to a significant improvement in plane design, featuring a unique adjustment mechanism. This patent date can be used to narrow down the manufacturing period of a Stanley plane to the late 19th century.
Can I use the manufacturing code to determine the exact production date of my Stanley plane?
+While manufacturing codes can provide valuable information about a plane's production date, they are not always precise. The "SW" code, for example, indicates that the plane was manufactured during the Stanley Works era, but does not provide a specific date. To determine the exact production date, it's essential to consult with a collector or expert and examine the plane's physical characteristics and markings.
In conclusion, dating a Stanley plane requires a combination of knowledge, research, and careful examination. By analyzing patent dates, type studying physical characteristics, examining blade markings, and decoding manufacturing codes, collectors and enthusiasts can gain a deeper understanding of their plane’s age, value, and history. Whether you’re a seasoned collector or a newcomer to the world of woodworking, understanding the history and evolution of the Stanley plane can provide a fascinating glimpse into the world of traditional craftsmanship.
