Whitney “Beals Patent” by Ed Buffaloe This seven-shot pocket revolver was manufactured under Fordyce Beals’ patent number 11,715 of 26 September 1854. Many such guns saw use during the American Civil War. The design is known as the “walking beam.” The cylinder is rotated by pushing the ring trigger forward and pulling it back, at which point it contacts the sear and releases the previously cocked hammer. The walking beam engages a cut on the front of the cylinder, then on the rear. The gun looks distinctly different from most other revolvers because of the cover over the left side of the cylinder, which supports the walking beam mechanism. The Beals Patent revolvers were successful by comparison with Whitney’s previous efforts at pistol making, selling a total of about 3200 through the end of the Civil War. The Whitney Navy revolver of 1857 (also strongly influenced by Beals, who would later design revolvers for Remington) was more successful by an order of magnitude, selling approximately 33,000. The Whitney Beals was offered in .28 and .31 caliber with six- or seven-shot cylinders. The revolver shown here has been modified to accept cartridges. It is not known whether this modification was performed by Eli Whitney, Jr. or someone else, but Whitney did not retire until 1888 so he could well have done the work. While researching information on the Whitney Beals revolvers I came across an article on the Eli Whitney Museum’s website regarding some archeological work done on the site of the original Whitney Armory. From it I learned that the frames for the Whitney Beals and Whitney Navy revolvers were cast from iron rather than forged from steel. This had been unknown prior to the archeological research at the Armory--they found crucible fragments all out of proportion to the known amount of brass used by the Whitney Armory, and eventually discovered they were used to cast iron rather than brass. All other parts (with the exception of butt plates) were made of forged steel. A person who is more knowledgeable than the author about metallurgy has suggested that what Whitney used was what is known as malleable iron. After being cast the iron is heat treated, which apparently changes the crystalline structure of the iron and allows it to be bent, stamped, or cold formed without breaking.
