Abstract

164,154. Lake, S. March 9, 1920. Stands or supports for portable machines.-Heavy portable tools are readily positioned for working, by being mounted on an extensible lazy-tongs arm. Four sets of lazy-tongs 3 forming a rectangular prism are linked at one end to a frame 7 carrying the balance weight 10, and at the other end to a frame 7<1> in which is revolublv mounted a spindle 11 carrying the swivelmounted tool-driving motor 13. The lazy-tongs are supported at intervals by guide frames 8, and the whole arm so formed is pivoted in the fork 2 swivelling in the stand 1 which is adapted to be secured temporarily to the work. The weights of counterbalance and tool, and the proportions of the arms are adjusted so that the system is always in neutral equilibrium.
