American Machine & Tool Co., Inc. (abbreviated AM&T or AMT) was established in 1928, although they seem to have kept a low profile until after World War II. In 1947 they began advertising inexpensive home-shop machines in Popular Science and Popular Mechanics. Within a few months they were using the name Marcus-Pollak on some of their machines. Many of the ads mentioned Marcus-Pollak and not American Machine & Tool Co., Inc., which caused us to believe for some time that Marcus-Pollak was a separate makers. Not so; trademark filings make clear that AMT was the originator of that name. "Pollak" was likely Abraham Pollak, their machine designer and the vice president of the company. In the early 1990s Samuel Marcus was Vice President so an old relative, perhaps his father, was presumably the "Marcus" in "Marcus-Pollak".
In early 1952 AMT started using the trademark Plana Centric to refer to their patented blade tilting mechanism in their tablesaws. At the same time they started using the name Yolands Precision Tool Co. of Boston as the name at the bottom of their magazine ads. We don't know the nature of the relationship between Yolands and AMT but we have not found a single mention of Yolands except as a name in ads for AMT machines.
Within of few months of introducing the Plana Centric and Yolands names, the Marcus-Pollak name was dropped. One minor exception was a 1953 ad from Yolands that featured a small circular logo with "American Machine & Tool Co" around the perimeter and "MP / Quality" in the middle.
Another trademark we have seen on a few AMT machines is Amco. Besides the machines sold under their own names, AMT also sold machines under Craftsman name through Sears, Roebuck & Co.; these AMT-made Craftsman machines have the model-number prefix of 149.
AMT continued to manufacture home-shop into the 1980s but they also began importing machines from Taiwan and China. Please note that these Asian-made machines are outside the scope of this website and pictures and manuals of those machines should not be uploaded here.
For some time, AMT has specialized in the design and manufacture of pumps. In February 2002, AMT was acquired by Gorman-Rupp Co. of Mansfield, OH. AMT no longer has any information on their old woodworking machinery products, and does not provide support for them.
