Abstract
"IMPROVEMENTS IN THE CONSTRUCTION OF PEDAL CONTROLS FOR THE DRIVING OF ELECTRIC MOTORS OF SEWING MACHINES", characterized by the fact that to achieve the immobilization of the motor when it is not powered by the electric circuit, a brake shoe is provided. which presses against the brake ring provided for it in the electric motor, while at the same time this brake ring is the housing of the engine cooling turbine, thus achieving a better compactness, providing an actuating lever which is moved by the pedal of the sewing machine with the displacement of which lever occurs the lifting of the brake shoe and therefore the release of the motor and then by means of a roller emerging from the free end of the lever is governed the position of the ends of the group of metallic contacts of opening and closing of different electric circuits, closes the electric circuit of accionam the motor and the time itself closes the circuit of augmentation of the electrical resistors in series to obtain the slow running of the motor, with which with the rise and fall of the free end of the lever the electrical resistors are left or put into work precise and thus achieve the most convenient speed, there being a spring to recover the resting and braking position of the lever, this spring being linked to the lever and the housing housing thereof.
