Definitions
- the present invention relates to cam mechanics used for the formation of shed on weaving machines.
- the reference 1 designates one of the oscillating levers coupled to one of the heald frames CL of the weaving machine, while the reference 2 corresponds to the two rollers which are offset laterally with respect to each other to cooperate with the two tracks of a complementary cam 3, wedged on a drive shaft 4.
- the various oscillating levers 1 of the mechanical under consideration are mounted idly on a common axis 5 oriented parallel to the shaft 4 and one observe that each of the ends 5 a with a small diameter of this axis 5 is supported by an eccentric 6 with a circular profile, housed in the cylindrical bore of a bearing 7 secured to the frame of the mechanics.
- the present invention is based on the observation that fitting of the ends 5a of the shaft 5 within the eccentric 6 and the maintenance thereof in the bearings 7 impair the rigidity of attachment of said axis so that during normal operation (weaving) of the mechanics, this axis is subjected to very high forces and to significant vibratory effects. These forces and vibrations cause rapid wear of the parts which support the pivot axis, causing the formation of rust in the bearings 7, as well as the appearance of a residual play detrimental to the proper functioning of all of the mechanics. .
- the invention essentially consists in making act on the ends of the pivot axis of the elastically prestressed means capable of exerting on said ends a force which immobilizes them against fixed bearing surfaces integral with the frame.
- these eccentrics are in the form of two lateral arms 10 whose upper end supports, for example by means of screws 11, the corresponding end 5 a of the axis 5, while the lower end is mounted on a pivot 12 secured to the frame 9 of the mechanics.
- each arm 10 is coupled by a connecting rod 13 to a cylindrical eccentric 14 engaged in a bore of the frame 9 and provided with a rotary operating means, shown diagrammatically in the form of a handle 15, suitable for move between two fixed angular limit stops indicated in 15 '.
- the eccentrics 14 are oriented in such a way that the links 13, established at an arcuate profile so as to be susceptible to a slight elastic deformability along their axis, tend to elastically push the arms 10 in the direction of the shaft 4.
- the system applies to the pivot axis 5 an elastic preload which tends to maintain its ends applied against two supports 9 has provided for this purpose in the frame 9.
- the shaft 5 is thus perfectly immobilized and in this way the wear and tear generated by the vibrations imparted to this axis 5 is avoided during weaving.
- the elastic prestress thus created extends its beneficial effects to the entire control system, avoiding any appearance of rust at the joints. It will also be observed that the two positions according to FIG. 2 and 3 are perfectly stable, the two lateral assemblies 13-14 being comparable to toggle joint systems with exceeding dead center due to the limitation of angular displacement introduced by the two stops 15 '.
- the ends 5 a of the axis 5 are carried by eccentrics or arms 10 established at a short length, in the manner of crank pins oriented radially with respect to said axis.
- the free end of each arm 10 is coupled to an arcuate link 13 which is linked to articulation to the frame 9 by means of a lateral pivot pin 16, located between the axis 5 and the shaft 4.
- the ends 5 a of the axis 5 are engaged in slots 9 b formed in the frame 9, the axis of each slot 9 b being oriented substantially orthogonal to the guide direction exerted by the links 13 on the arms 10 when these pivot to pass from the weaving position according to fig. 5 at the leveling position according to fig. 6.
- At least one lateral jack whose cylinder 17 is articulated in 9 c on the frame 9, while the movable rod 18 is coupled to an ear 10 a of the arm 10 considered .
- the average position of the ear 10 a is perpendicular to the axis of the jack 17-18, so that actuation of the latter results in a rotation of the arms 10 and the shaft 5 resulting in the transition from a to the other of the arrangements shown in fig. 5 and 6.
- a stop 13 ' is provided to limit the amplitude of the angular displacement of the rods 13.
