Abstract

Improvements in sewing machines, characterized in that it comprises a smooth cylindrical bushing mounted coaxially and fixed to the receiving shaft by means of an intermediate disk, so that two annular cavities are formed between the inside of the corresponding part of said bushing and the shaft , in whose cavities a substantially cylindrical piece is mounted free with respect to the shaft and the bushing and provided with peripheral notches that determine with the cylindrical surface of said bushing triangular housings of curved walls in which are located rollers driven by a spring fixed in a cavity of a step that determines in the lower part the termination of the inclined surface, so that said piece is fixed to a disc provided with a projection to the end of which a connecting rod is hingedly coupled, articulated at its other end to a solid crank with the motor axis, the movement of this one transformed a in the inner part in reciprocating reciprocating motion and in the outer sleeve and therefore in the receiving shaft in an alternative movement by impulses of advance in a single direction, the conversion being carried out by means of said rolls that only transmit the movement when they are pressed by the two surfaces between which they are mounted, absorbing the inverse movement.
