Definitions
- the present invention relates to Jacquard machines for training of the crowd on the weaving machines and it concerns more particularly the mechanism for the vertical actuation of the two series blades that control the hooks of the same mechanism.
- a single shaft is provided which is linked to the main shaft of the weaving machine and which spans the entire length of the mechanical frame.
- this tree which is rotated continuous, is equipped with two adjacent cam or eccentric systems suitable for transforming this continuous rotation into an alternative rotation in order to give the levers which carry the claw frames the desired lowering and lifting movement.
- the invention consists in providing on the input shaft linked to the weaving machine a unique cam mechanism capable of imparting movement alternating rotation with two longitudinal shafts arranged coaxially one inside the other to control the levers associated with the blades.
- the two coaxial shafts are arranged above the hooks, along the axis longitudinal median of the mechanics, so as to free access to said hooks.
- the outer tree is cut out with lights arranged to allow the passage and the angular movement of the integral levers of the inner shaft, these levers being oriented radially in pairs to define four control beams.
- These plagues are linked by links to horizontal bars which are guided vertically on the one hand by means of fixed slides, on the other hand by means of connecting rods which pivot on the frame. It is on these bars that the blades for controlling the mechanical hooks, these blades can be independent of each other or be attached to two frames of claws.
- Fig. 1 is a schematic axial section of the actuation mechanism a Jacquard mechanism established according to the invention.
- Fig. 2 illustrates in perspective the arrangement and positioning of the mechanism according to fig. 1.
- Fig. 3 shows the mechanical frame, prior to assembly of the actuation mechanism according to fig. 1 and 2, as well as hooks.
- references 1 and 2 designate two vertical plates which belong, as will be seen below with reference to FIG. 3, to the fixed frame of the illustrated mechanics.
- the face of the plate 1 which is turned towards the outside has a lateral extension 1 a shaped so as to define a sort of lateral casing closed by a cover 3.
- an input shaft 4 which extends externally opposite the plate 2 to be connected, by a coupling such as that referenced 5 in fig. 2, at the end of a shaft 4 has been driven in continuous rotation by the shaft of the weaving machine with which the Jacquard mechanism is associated.
- the periphery of the discs of the two cams 5 and 6 forms a raceway for rollers 8 (shown in the form of arrows in fig. 1) which are carried by the radial arms, facing away from each other and axially offset from one another, by two rockers 9 and 10.
- the rocker 9 is fixed at the end of a shaft 11 mounted inside a outer shaft 12, of length slightly less than that of the shaft 11.
- the two coaxial shafts 11 and 12 are suitably supported at rotation in bearings reported in plates 1 and 2 and they are oriented along the median longitudinal axis of the mechanical frame, at the top of it.
- the cam mechanism housed in the housing 1 a -3 ensures the transformation of the continuous rotational movement of the input shaft 4 into an oscillating movement, so that the two coaxial shafts 11 and 12 are driven by an alternative movement, in synchronism with each other.
- the outer shaft 12 is cut out from two slots 12 a , axially offset from one another and oriented opposite one of the other.
- Each of these slots 12 a is crossed by a lever 13 fixed radially to the inner shaft 11.
- each lever 13 is provided a lever 14 radially integral with the outer shaft 12 along the axis of the corresponding lever 13 and it is understood that each of the pairs of opposite levers 13 and 14 constitutes a sort of plague which the two concentric shafts 11 and 12 animate with an oscillating movement.
- Each lever 13 and 14 is pierced with an arcuate light 13 a , respectively 14 a , for the adjustable fixing of a vertical link 15 (fig. 2) whose lower end is coupled to an actuating bar 16.
- Au level of each plate 1 and 2, two bars 16 are therefore provided arranged side by side.
- each bar 16 is associated with a horizontal rod 18 provided in double form to embrace the bar considered.
- One end of each connecting rod 18 is coupled to the corresponding bar 16, while the opposite end pivots at 19 on the fixed frame.
- the two pairs of bars 17 provided to the right of the plates 1 and 2 are intended to control two series of blades or horizontal knives 20, with a view to actuating the usual hooks for actuating the arcades of the mechanics.
- the connection between the bars 16 and the blades 20 was operated using lines or rods 20 a , said blades being thus made independent of each other; it goes without saying, however, that two claw frames can be used, in the usual manner.
- the general operation of the mechanics is identical to that of conventional constructions, in the sense that the oscillating movement of the two coaxial shafts 11 and 12 ensures the lifting and lowering of the two series of blades 20.
- the arched lights 13 a and 14 a flails 13-14 allow obtaining an oblique crowd, when desired.
- the raised central arrangement of the coaxial shafts 11 and 12 completely releases the lateral access to the mechanical hooks.
- the latter comprises only a single pair of conjugate cams, disposed in the casing 1 a -3, that is to say outside the frame, which further improves accessibility to the mechanical components.
- this frame can be constituted by two lower beams 21 with a C section open towards the outside, on which the two plates 1 and 2 are directly fixed which support the coaxial shafts 11 and 12.
- a transverse flange 22 arranged for the mounting of the shaft 4 is linked to the weaving machine.
- a series of spacers 23 which are fixed to two longitudinal blanks 24 forming supports for the slides 17 of the bars 16 and for the pivots 19 of the connecting rods 18.
- At least some of the spacers 23 are cut out from vertical openings 23 a (cf. fig. 2) for the passage of the blades 21. The latter are thus able to operate the hooks vertically (shown in C in fig. 3) arranged in rows in the housings defined between the plates 1 and 2 and the spacers 23.
