Also known as: Brooklyn Arms Slocum, Slocum Side-Loading Revolver, Slocum's Patent Sliding Sleeve Pocket Revolver

Overview

The Slocum Pocket Revolver is a five-shot single-action revolver manufactured by the Brooklyn Arms Company of Brooklyn, New York, in 1863 and 1864. Chambered in .32 rimfire, it used an unusual side-loading mechanism patented by Frank P. Slocum in which individual sliding sleeves forming the sides of each chamber were drawn forward to load metallic cartridges, an arrangement devised to circumvent Rollin White's bored-through cylinder patent then held exclusively by Smith & Wesson. The standard pistol featured a scroll-engraved, silver-plated brass frame, blued barrel and cylinder, casehardened spur-trigger hammer, and two-piece bag-shaped rosewood grips.

Notes

To load, the revolver was placed at half-cock, the cylinder turned to align each chamber with a frame plunger, and a small lever at the rear slid the separate chamber covers forward over the cartridges. Sighting was rudimentary, with a bead front sight and a topstrap groove at the rear.

Background

Frank P. Slocum's side-loading cylinder was one of several ingenious Civil War-era attempts to skirt the Rollin White bored-through cylinder patent, which gave Smith & Wesson a near-monopoly on practical metallic-cartridge revolvers until it lapsed in 1869.
