Aceliner "Stapling Machine" Stapler, designed by William G. Pankonin for Ace Fastener Corporation. Panokin applied for a patent for his "Stapling Machine" on Mar. 26, 1941, which was granted on May, 20, 1941 (see Patent Description below). Also note photo showing a scan of the original diagram, which submitted to United States Patent Office, at the time of application.

This is a Version 1 (1st edition), Model 502, measures 7.75" in length and 1.7 inches in width. Constructed of steel parts, which were advertised as “triple-chromed.” and a stream-lined The "Emerald Green" handle and decorative plastic disc inside the push-rod head, was made of a plastic-like product called "catalin" (not bakelite). It weighs a hefty 1lb 4 oz and sits firmly on 2 rubber feet.

Although the 502 was advertised (and bottom of stapler marked), as needing specific Ace #2025 or 20253 staples, these "specific" staples are exactly the same as standard-size staples. The magazine will hold a full strip of 210 staples. There is also a sliding anvil that will allow you to change between permanent and pin clinches. And of course you can use the Aceliner as a tacker by rotating the base 180 degrees.

This beautiful, mid century "Ornamental Design" stapler has been tested and in excellent working order (may still have a staple or two in it). Very minimal wear to chrome, the top 3 catalin mounting rivets show some oxidation, but no chips or cracks to catalin. Overall, an exceptional piece for your desk or your collection.
