Abstract: Device for automatically loading a machine tool, particularly a shaving machine, comprising on the one hand a chute conveying the workpieces, particularly gears, to a loading station, on the other hand an equipment whose support is mobile in translation along a rectilinear slide by means of a double-acting hydraulic or pneumatic ram, said slide extending at least between the loading station and the work station of the machine tool. The mobile equipment comprises two units each comprising two arms, the two arms of the front, unloading unit as well as the front arm of the rear, loading unit, being mounted to pivot on the sliding support. A linkage connects the three pivotal arms and is coupled to a double-acting hydraulic or pneumatic ram, mounted on said support and ensuring the passage of the pivotal arms from a high position to a low position, and vice versa.

Abstract: Shaving machine in which a motor controlling the cutting feed is coupled to a work-table which can move relative to the frame. The cutting feed motor is a direct current motor and the control device of this motor comprises several circuits for energizing the motor corresponding to at least two and preferably three different speeds of the motor in one rotation direction, and at least one speed in the other rotation direction.A special application of the invention is to the shaving of gears.
