Definitions
- the present invention relates to double-lift armor mechanics with open pitch intended to be associated with a loom in order to lift certain warp threads and lower others to allow the insertion of weft threads or picks .
- Mechanics of the kind in question include two claw frames intended to cooperate with the hooks in order to raise a part of them and lower some others in order to open the pitch.
- the frames slide relative to a central vertical slide.
- the present invention relates more particularly to the control of opposite alternative movements of these frames.
- Mechanics known hitherto of the kind described in Japanese utility model No. 1,134,034, comprise on each of their lateral faces two pendulums each associated with two connecting rods hinged moreover to the two frames.
- the first balance is provided with an alternating movement communicated by one end of a control lever, the opposite end of which is associated with a crank whose rotation speed is twice as slow as that of the shaft of the loom.
- the reciprocating movement of the first balance is transmitted to the other balance by means of a connecting rod which gives it a tilt in the same direction as that of the first.
- the connecting rods associated with each frame are parallel to each other and are articulated on the arms of each pendulum.
- the inertia effects of the connecting rod and the control lever are added to the pivot axis of the first balance.
- the two pendulums exert important actions in the same direction on the mechanical chassis.
- the control rods of the frames communicate to the central slide, and for each of them, forces in the same direction.
- the position of the point of articulation of the control lever on the first balance has been determined so that there is a single orientation of the balance which corresponds to the point of intersection of the claws, this orientation being determined twice per cycle by two positions in large diametrically opposite of the crank. Once this orientation has been determined, it suffices to obtain the desired result by choosing the points of articulation of the connecting rods on the pendulums and the length of the latter so that at this orientation the two de.griffes frames are at half their stroke, that is to say that the mechanics are in the so-called claw crossing position.
- the link rod connecting the pendulums causes a reverse tilting of the second relative to the first in order to cancel the reactions on the frame to reversals of direction of rotation, while the control rods of the frames are oriented way symmetrical in order to balance the reactions on the vertical guidance of the frames.
- a usual armor mechanism is controlled by a rotating shaft 1 with which is associated a crank pin 2 carried by a radial arm 1a and on which is articulated one of the ends of a control rod 3 whose opposite end is pivotally mounted relative to an axis 4 provided at the end of a cross-shaped pendulum 5, which rotates around a fixed axis 6.
- a connecting rod 7 joins the balance 5 to another balance 8 pivoting about a fixed axis 9.
- the two ends of the horizontal branches of the two pendulums are coupled to connecting rods 10, 11 - 12, 13 respectively articulated two by two to the upper frame 14 and to the lower frame 15. It is observed that the two frames in question move vertically in opposition by being guided by a central vertical slide 16.
- crankpin 2 When the crankpin 2 rotates while being driven by the shaft 1, it causes the pendulum 5 to tilt which causes that of the pendulum 8 whose movement is identical to that of the first.
- this pendulum comprises a plate 19 in the form of a "bell return" which constitutes a hub for the rotation of the pendulum relative to the fixed axis 6.
- a plate 19 is articulated one of the ends of the connecting rod 7, the opposite end of which is hinged to a plate 20 forming part of the second balance 21, said plate constituting the hub of the latter with respect to the fixed axis 9.
- the bell return 19 and the plate 20 are associated with two suitably braced sheet flanges which include lights 18a, 18b, 21a, 21b intended for fixing the lower ends of the control rods of the claw frames 14, 15.
- the fixing of said lower ends is effected by an arrangement making the subject of a prior patent of the present plaintiff.
- each of the connecting rods 10 and 11 which are fixed in the slots 18b, 21a of the two rockers diverge in the upward direction to come to articulate on the upper frame 14, while the connecting rods 12, 13 start from the slots 18a, 21b and converge in order to be subjected to the lower frame 15.
- Each of the connecting rods comprises a usual device making it possible to lengthen or shorten them, each of these devices being referenced 22.
- the balance 18 switches for example clockwise, but the position of the connecting rod 7 causes a tilting in the opposite direction of the balance 21, so that by placing judiciously the lower ends of the connecting rods in the slots 18a, 18b and 21a, 21b it is possible to obtain a vertical movement in opposition to the frames 14 and 15 under the conditions described above, that is to say by eliminating the effect of inertia of the two pendulums and by eliminating the forces on the slide 16.
- This determination of the location of the ends of the connecting rods in the slots is calculated in such a way that at the point of intersection of the claws, correspond two diametrically opposite positions of the crankpin 2.
