Description: |
| "My invention relates to routing machines of the portable type having an open ring-shaped base, and it my object to provide such a machine which is of extremely light construction to facilitate handling by the operator. More particularly it is my object to provide a machine in which a very fine vertical adjustment of the motor is obtained by slidably mounting the motor on a pair of posts, which server also as handles for the two hands of the operator, and are of such construction as to interfere to the least possible degree with the view of the operator." |
