  A DEVICE INTENDED TO TRANSMIT ENERGY FOR THE

DIRECT CONTROL OF MACHINE TOOLS.

  
.... The present invention relates to the direct control of machine tools by electric motor, with reduction gear at two different speeds and tension by lever. Of the belt.

  
This device is itself controlled by an electric motor M on which is wedged at the end of the axis a gear pinion A with 21 teeth. This motor is fixed on a flange B; this B oscillates concentrically in the .carter C which is held in place by the circular clamp

is engaged with the M which is equivalent to the direct cocmnde of the gear A with the M, while, by engaging in L we pass through the gear G which acts as reducer. Gear M is focused on shaft N which rotates on bearings <EMI ID = 5.1>

thus the cantilever. The housing C and the cage P 'are supported by rack pistons Q and QI, which themselves are

the S axis which, by acting in one direction or the other, can give tension if necessary or relax the belt to change the step of the pulleys. Two coil springs X and XI are designed to balance their resistance corresponding to the weight of the device; so that by acting on the lever U one only has to transmit the tensioning or slackening movement of the belt. A button Vmunid'un

the provisions thereof. A support W allows the speed reducer to be mounted on any base or on a wall.

CLAIMS.

with the simple movement of a lever, it is possible to obtain the doubled number of speeds of machine tools.

moved by a single lever, allows you to adjust the tension of the belts at will and to facilitate the relaxation to change steps without the help of poles or others (without stopping the machines).
