Albert G. Bagley was awarded patents in 1846, 1847, and 1850, related design and manufacture of an emerging writing instrument technology evolution in the United States.
Albert G. Bagley's patent number US4991A, dated February 27, 1847, Forming Metallic Pen-Barrels by Drawing, was a significant innovation in the manufacturing of metallic pen-barrels. Bagley's invention involved forming the barrels by drawing them through a series of dies, which allowed for greater precision and consistency in the manufacturing process.
Bagley's invention had a significant impact on the Gold Pen business penholder manufacturing process, as it enabled the production of more uniform and reliable pen barrels. Prior to Bagley's invention, pen barrels were often made by hand, which resulted in significant variations in size and shape. Bagley's invention helped to standardize the manufacturing process and improve the quality of the final product.
Later patent citations for 20th and 21st century medical field and appliance manufacturing patents further highlight the significance of Mr. Bagley’s discovery.
In addition to its impact on the gold pen manufacturing process, Bagley's invention has also been cited in a number of 21st century Global Medical Field Patents. For example, global patent numbers EP4011303A2, EP3510945A1, and EP3782576A1, each titled "Occlusion Device" and awarded from 2019-2022 and described variously as an implantable device for vessel occlusion or an occlusion device for implantation into a body lumen or aneurysm, each cite Bagley's invention as a foundation reference in the development of a new manufacturing process for life-saving arterial stent components.
Similarly, US patent number US5727581A (now a Global Patent), titled "Dishwasher spray-arm assembly", originally filed by General Electric Company employees in 1996, cites Bagley's invention as a key reference in the development of a new manufacturing process for dishwasher spray-arms, again demonstrating the remarkable foundation of Bagley’s manufacturing process. This patent is mistakenly classified B43K1/04 Split nibs with broadened tips, and is clearly a pioneer status patent.

Overall, Bagley's patent number US4991A was a noteworthy innovation in the manufacturing of metallic pen-barrels that enabled Bagley to save time and money in the manufacturing process which resulted in his pen factory producing products for peers cheaper than they could themselves produce. Moreover, its impact can arguably be seen in the Medical and Appliance Manufacturing fields today.
The depicted Gold Pen Extension Holder is the earliest example of patent 4,991 discovered. Constructed of an undetermined metal alloy, the pen holder was equipped with an early experimental bimetallic Gold/Silver nib stamped "Diamond Pointed". The dimensions of this early Bagley Extension Pen Holder are quite small, Closed, 2.25 inches and Extended with nib, 4.313 inches. Note the magnified imagery superimposed on the patent. The rightmost magnified image exhibits the use of a concentric swage tool, a sophisticated technique in the 1840's.
