Edward Krantz was a man with a vision. His idea was to create a mechanism wherein the amount of force used to insert a staple would always be constant regardless of how hard or soft you depressed the plunger. This would reduce or eliminate wasted staples. When coupled with the inexpensive pressed steel parts, low quality enamel and the removal of any and all parts that did not serve a necessary purpose or that complicated manufacturing and you have yourself an inexpensive to purchase and inexpensive to operate paper fastening device.
The Krantz stapler was produced by the Krantz Manufacturing Company of Chicago, Illinois. This stapler would be considered the grandfather of the Trigger Action Stapler which was also invented by Edward Krantz. On the bottom of the base is engraved “Krantz Mfg Co” and “Chicago Ill Pat Apld For”. The patent for this item was applied for on February 28, 1931 and granted on July 25, 1933. However, at the time the patent was granted it was also assigned to the A.L. Hansen Manufacturing Co. That means that the Krantz Stapler would have been produced between February 1931 and July 1933.
This stapler was produced after 1933 but it was manufactured by A.L Hansen and called the Kling-Tite. It should also be noted that every stapler of every type that I’ve found made by A.L. Hansen used this special stapling mechanism.
The Krantz weighs 1 lb and 10 ounces empty and measures 7.375″ L x 2″ W x 4.688″ H. It is made of pressed steel and mostly painted black except for a few parts. The cylinder screw and anvil are polished steel while the plunger handle and cylinder cap are chromed.
While Krantz’s special plunger design was a winner, the stapler itself was not particularly successful. It suffered from cheap parts and some questionable design decisions such as not fully-encasing the spring for the staple push rod but instead allowing it to be in the open where dirt and grime could gum it up. This also allowed for easy contamination of the internal mechanisms. While I’m sure it made manufacturing easier, it also ensured that Krantz wouldn’t have to worry about producing a lot of these staplers.
