  Device for converting a rotary movement of a certain size into a rotary movement of variable size in automatic embroidery machines for moving the gate.



   For the automatic movement of the gate of embroidery machines, movements of a certain size have to be converted into such variable size. So far they had
 EMI1.1
 by which the precision of the movements, which determined the quality of the embroidery, was negatively affected.



   According to the invention, more than two groups, each forming an arithmetic row, have exclusively rotating motion elements, e.g. B. gears, together whose movements are united by differential gears.
 EMI1.2
 the movement component to be transferred to the embroidery frame, the waves placed in one plane, FIG. 3 a section along line AB of FIG. 2 and FIG. 4 a section along line ('D of FIG. 2, the waves not in these last two figures are placed in a plane, but have retained their real position.



   1 and: 2 are two coaxial, one behind the other, forming a wave train
 EMI1.3
 connected to the shaft 2 by a reversing gear 5 in and of itself known construction so that it)) always jerks the width by the same angle, but in the opposite direction to the shaft 2. The reverse gear 5 has two to the
 EMI1.4
 is the same size as the gear 6, the gear 7 is the same size as the gear 10 and the gear 11 is the same size as the gear S.



   To the wave train 1, 2 six waves (Fig. 1 and 3) are arranged, of which the
Shafts 12, 13. 14 to the gear mechanism of a movement component and those in FIG
 EMI1.5
 component belong. Since both are the same, only that of shafts 12, 13, 14 is dealt with in the following. As is well known, the two movement components are used to: mf the embroidery frame to be transferred, so as to the resulting embroidery frame displacement

   The shaft 34 protrudes from a box 44 enclosing this gear (Fig. 1) and carries a sprocket 45 which is connected by a chain 46 with a above the
