This patent is interesting because it is for a moving-arm radial arm saw. DeWalt originated the design where the motor is attached to a moving carriage that travels on a fixed arm. Others, presumably to evade Ray De Walt's patents, created a different design, where the motor is affixed to the end of the arm, and that entire assembly reciprocates. The latter design has the advantage that the arm moves out of the way when the saw is pushed back, but it has two disadvantages: it is more difficult to make the saw move easily yet precisely, and the arm projects quite a distance from the rear of the table. This last disadvantage is nearly fatal, and makes these saws very difficult to accommodate. They cannot go against a wall unless a hole is cut for the arm, and if they are placed away from the wall where people can walk behind the saw, then the moving arm is a safety hazard. DeWalt did produce this saw, but it was not very successful.
Besides several DeWalt-badged examples of this design, we have also seen one labeled, "Victory Motors, Incorporated". Inventor Ewald Schutz had worked for DeWalt since at least 1939 so it seems very unlikely that Victory Motors was a firm acquired by DeWalt. Our best guess is that Victory Motors was a small and short-lived company that produced this saw as part of the war effort, probably for military use. |
