The Clipless Stand Machine is not a stapler, but what is often referred to as a stapleless stapler. The difference being that this fastener does not use staples, brads, pins, etc. but simply fastens the paper by only using the paper itself. In this case it works by making two cuts in the papers to be fastened. One is an elongated U-shaped tab and at the base of the tab a small straight slit. The tab is then folded into the slit to fasten everything together.
Introduced in 1911 it was available until at least 1921. This weighs in at 2 pounds of nickel-plated steel. It is 5.25"L x 2.25"W x 5.5"H.
