Abstract

178,424. Oudet, J., and Koeniger, A. April 13, 1921, [Convention date]. Supports for portable machines.-Portable drilling, boring, riveting, screw-cutting, and like machines operated pneumatically, electrically, or by mechanical power are adjustably suspended so that the operator is relieved of the weight of the machine and of its torsional reaction when in use. The machine is mounted in a yoke 3, Fig. 2, which is pivoted in a telescopic support 6, 8 suspended by a hook 9. The inner sleeve is balanced by a weight 10, which may be increased by adding weights 15, and is guided on the outer sleeve by rollers 11. In a modification, Fig. 7, several machines 1 are adapted to be supported by a series of counterweighted levers 17, Fig. 5. In this modification the members 6, 8 are adjustably locked by a pin inserted in one of a series of holes 21. In a further modification the machine mav be mounted in the forked end of a long rigid rod which is supported by a counterweight chain.
