Improved clutch for an automatic berth in machine tools.

摘要

improved clutch for an automatic lashing machine tools, including two aligned hollow shafts or rods of which the upper is attached to a geared motor with torque limiter in one direction and the bottom, through a fluted, a asparagus onto the spindle of the machine tool and threadable to the tool characterized carte that the lower rod is mounted central axial on a cylindrical jacket piece stepped cup-diameter fitting slidingly on dei casing joint forming a movable package axially, by the air inlet pressure in a chamber formed in the step of diameters, against an upper spring so that said movement allows nesting of diametrically opposite radial expansion of the upper end of the lower shaft, between the opposing projections of a formed at the lower end of the rod and upper plate trans direct mission movement when acting air pressure and producing the automatic disengagement by the action of the spring when said pressure ceases.
