Definitions
- the present invention relates to improvements made to back and forth movement control mechanisms for claw frames armor mechanics.
- the present Applicant developed and used around 1975 a mechanism control of the back and forth movement of the claw frames armor mechanism with rotating hooks called CR 520, consisting of essentially by a set of two complementary cams mounted on the mechanical control shaft and which each cooperate with a follower roller mounted on a rocking lever freely pivoting around an axis, said rocker being connected to each frame of claws by two complementary rods, respectively long and short.

- the improvements which are the subject of the present invention aim to allow the realization of a control mechanism of the kind in question, which is applicable to large claw frames and whose guidance is reduced to the strict minimum.
- control mechanism is characterized in that the camshaft is provided on each side of the frame a second set of two complementary cams angularly offset by 180 ° with respect to the first cooperating each with a follower roller mounted on a second double rocker placed side by side with the first and which is connected to each claw frame by means of two connecting rods respectively long and short, so that a frame of claws either driven by the two short rockers of the rockers, both of which long connecting rods drive the other frame of claws.
- the entire mechanism which is located at made at the bottom of the frame of the armor mechanics can be arranged in a casing ensuring its lubrication by bubbling.
- FIG. 1 There is shown schematically in FIG. 1 the frame 1 of a mechanical of armor comprising two claw frames 2, 3 moving back and forth vertically thanks to a mechanism according to the invention.
- This mechanism includes two identical sets located on each side of the frame 1, as illustrated in fig. 2.
- a transverse control axis 4 rotated in the usual way from the weaving loom with which the mechanics shown is associated.
- the axis 4 has at each of its ends projecting out of the frame a quadrangular endpiece 4 a on which are wedged two groups 5, 6 of two complementary cams.
- the first group 5 located furthest to the outside has two complementary cams placed side by side 50 and 51.
- the second group 6, placed further inside on the nozzle 4 a is composed of two complementary cams 60, 61 .
- the periphery, of suitable profile, of the cam 50 cooperates with a roller follower 7 secured to a two-arm rocker 8, while the periphery of cam 51 is in contact with a follower roller 9, also integral with the rocker 8.
- the latter is pivotally mounted around a transverse shaft 10.
- cam group 6 The periphery of the cam 61 is in permanent abutment against a follower roller 11, mounted on a second rocker 12 rocking around the shaft 10 in the immediate vicinity of the first rocker 8.
- the second cam 61 cooperates with a second follower roller 13 also mounted on the rocker 12.
- the second rocker 12 is articulated by its first arm to a connecting rod 16 disposed next to the connecting rod 14 and also articulated at upper claw frame 2.
- the second arm of the rocker 12 is associated to the lower frame 3 by means of a connecting rod 17.
- the two arms of the two rockers have lights curves 80, 81 respectively 120, 121 in which the ends lower of the four aforementioned connecting rods are pivotally mounted. he is obvious that by changing the position of the lower ends of the four connecting rods relative to the lights of the rockers, we cause either the variation in travel of the two frames 2 and 3, that is to say their obliquity.
- the geometric axes of axes 4 and 10 can be offset laterally by a value d , but it goes without saying that without departing from the scope of the invention, the two geometric axes considered could be located in the same vertical plane.
