Definitions
- the present invention relates to mechanics for the formation of the crowd on the weaving machines and it relates more particularly to the dobbies of the rotary type, that is to say in which the control of the alternating vertical displacement of each heald frame is provided by means of an oscillating rod, one end of which is coupled to said frame while the opposite end, cut out from an opening, is engaged on an actuating eccentric.
- the object of the present invention is to simplify the construction of the rotary dobbies according to the aforementioned French patent, without adversely affecting the reliability of the operation.
- each of the articulated hooks is profiled on its outer edge in order to cooperate, when actuated with uncoupling, with one or the other of two retaining latches mounted at two points diametrically opposite with respect to the dobby tree.
- reference 1 designates the frame of the dobby, which supports the main shaft 2 animated by the jerky rotation movement, which shaft is intended to control a series of oscillating connecting rods 3 each of which is coupled by a lever 4 to one of the heald frames 5 of the weaving machine associated with the dobby under consideration.
- each of the connecting rods 3 is cut, opposite its coupling point with its lever 4, an opening 3a which is engaged, with the interposition of a bearing 6, on the cylindrical periphery of an eccentric d 'actuation 7; the latter is mounted idly on the shaft 2 by means of a bearing 8.
- Each connecting rod 3 is associated with a drive disc 9 angularly secured to the shaft 2 and it will be observed that the periphery of this disc 9 is cut from two notches 9a, diametrically opposite one another. These two notches 9a are intended to cooperate with an articulated coupling hook 10 mounted on a small axis 11 carried by an overhanging plate 7a, laterally secured to the eccentric 7.
- Fig. 3 and 4 clearly show the profile of the hook 10 which has, on either side of its articulation axis 11, a selection arm 10 'and a coupling arm 10 ".
- the edge of this arm 10" which is turned towards the disc 9 has a projecting spout 10a, which is clean under the effect of elastic return means constituted by a spring 12 interposed between the plate 7a and the end of the arm 10 "of said hook, to be worn permanently against the free edge of the disc 9 and to engage, during each stop of the shaft 2, inside one or the other of the two notches 9a.
- the hook 10 is controlled, against the spring 12, by the end of two selector levers 13 (fig. 1) pivotally carried by two fixed axes 14 oriented parallel to the shaft 2.
- These pivoting levers 13 are coupled one to the other by a link 15 and one of them (the one on the right in fig. 1) has an extension on which two rods 16 are articulated which are moved transversely to their axis by two needles 17 controlled axially by a program 18 reading device with electronic or mechanical operation.
- the transverse displacement of the rods 16 under the effect of the needles 17 allows, according to the program incorporated in the device 18, to the said rods either to cooperate with two pushers 19 with reciprocating movement thereby ensuring the actuation of the two pivoting levers 13, or to escape the action of said pushers 19 while remaining stationary.
- a spring 20, interposed between one of the levers 13 and the frame 1, tends to spring back permanently in the direction of the shaft 2 the end of the lever 13 with which it is associated, and on the contrary to maintain the end of the opposite lever 13 spaced from said shaft, so that the action of this spring 20 is exerted in an antagonistic manner with respect to that of the pushers 19.
- a fixed stop 21 limits the tilting of the levers 13 under the effect of the spring 20.
- the selector lever 13 which is then placed at the level of the hook 10 receives no action from the reading device 18 (case of fig. 3)
- the spring 12 associated with said hook 10 elastically engages the spout 10a thereof in the notch 9a of the drive disc which is then placed opposite; there is therefore coupling of the shaft 2 and the eccentric 7 through the hook 10 and the disc 9, so that the connecting rod 3 is controlled.
- each of these latches 22 is pivotally mounted on its support 23 and receives the action of a spring 24 which tends to keep it applied against a fixed stop 25.
- the plate 7a of the eccentric 7 and the hook 10 itself can be constituted by flat parts having no camber or bending. It will be noted that the coupling and immobilization functions are grouped together in the same arm 10 "from the single hook 10, which makes it possible to obtain very high precision. In addition, and the point deserves to be underlined, there n 'There is action on the hook 10 that during the angular immobilization of the rod 3, which limits wear to a considerable extent.
