Winding device

Claim 2

Mechanical device for obtaining complex movements, characterized in that it consists of: a first means of causing the movement from one point whose projection on a given axis is a sinusoidal movement in respect to time at a determined frequency. a second means causing the movement of the first means in a way such that the projection of the point of movement considered along a given axis is the algebraic sum of a sinusoidal movement in respect to time at a determined frequency and of a sinusoidal movement in respect to time at a frequency three times that of the previous determined frequency, and the receptor means of the movement obtained.

Claim 3

Device following claim 1, characterized in that it includes the combination of: a first gear with fixed pins cooperating, on the one hand, with a second gear with a moving pin and, on the other hand, a third gear with moving pin, the aforesaid gears being aligned, a rigid mounted support oscillating around the pin of the first gear, integral with the pins of the aforesaid gears, a rod one of whose ends is integral with a point of a spoke of the third gear and the other end being integral with the device jig, a means of transmission between the first and third gears means of movement reception.

Claim 4

Device following claim 2, characterized in that the means of transmission is a fourth gear cooperating with the first and third gears.

Claim 5

Device following claim 2, characterized in that the means of transmission is a belt driving the first and third gears.

Claim 6

Device following claim 2, characterized in that the first gear is a motor gear.

Claim 7

Device following claim 2 or claim 5, characterized in that the diameter of the first gear is equal to that of the third gear and is three times smaller than the diameter of the second gear.

Claim 8

Device following claim 2, characterized in that the gears forming a meshing train, each of the two means of outer meshing of the aforesaid train being connected to the end of the rod, the other end of each of the aforesaid rods being respectively connected to the fixed jig of the device and to the receptor means of movement, giving thus to the aforesaid receptor means successive movements in one or the other directions.

Claim 9

Device following claims 2 or 7, characterized in that the receptor means of movement are such that the gear and cogged wheels to which the successive rotation movements are given in one direction or the other by means of a rod.

Claim 10

Device following claims 2 or 7, characterized in that the reception means of movement are such that a shaft in rectilinear movement successively in one direction and then the other under the affect of its connection to the corresponding rod to which it is connected.

Claim 11

Device following any one of the claims 2, 7, 8, and 9, characterized in that they include two gear trains arranged perpendicular to act together on a whip guide-wire integral with splined shaft on which are installed, on the one hand, a gear whose center hole is splined complementarily, on the other hand, by bushing which is integral with the aforesaid longitudinal shaft but free in rotation, one of the two aforesaid trains acts on the aforesaid splined gear, the other on the aforesaid longitudinal bushing, in a way such that the splined shaft and guide-wire which is integral with it successively carries out the required movements; a first translation movement, a first rotation movement of a half-circle in one direction, a second translation movement in the opposite direction from the direction of the aforesaid first movement, a second rotation movement of a half-circle in the opposite direction from the aforesaid first rotation movement, the motor-gears of each of the trains being simultaneously driven in a way such as to obtain the required successive movements.
