Shuttle braking device on looms

The invention relates to a Schütζenbremsvorrichtung on looms with one rotatably mounted on the shooter box Brake tongue.

The brake tongues on the loom's contactor box are known to have the task of web shooters when entering

in the iächütaeakatitea to decelerate utW. ia: J- ·; Livhat i ^ ie-r to stop in the same place * PIe voa α er brake aua _c e braking forces acting on the shooter are now with the usual brake additions & ueh then available when the shooter is driven out of the shooting box again in the event of a blow. In order to set the archer in motion, therefore, considerable striking forces have to be used, especially in those who are sniffing

in which the shooter has to accelerate very quickly, which must lead to rapid and severe wear of the striking parts. The greater thickness of the sleeve also requires a greater amount of energy and, in connection with the brake tongues that have been used up to now, has other deficiencies known to those skilled in the art result, such as gops tee, jumping back of the shooter, etc.

One has now smoked away this hangover by one of the treasures completely from the bridge during the strike the brake tongue relieved, and in the way "that the whole Breao tongue is pulled away from the shooter. That way will probably a relief of the shooter achieved, but is missing by the complete release of the brake pressure during of the stroke the leadership for the öchützöö, but which for © inen perfect scoreboard flight is absolutely necessary.

In other known braking devices, the shooter is relieved of braking pressure when the blow is hit by the fact that the force of the steciierfe or a special spring acting on the free end of the brake is partially or completely canceled without changing the position of the porous urigo, apart from the fact that With this arrangement, especially when the effect of the fire is completely abolished, the protection of the rifle is not exercised, the discharge of the guard is only then

noticeable if the same is already a bit timaton way in the SchütJsenkaeten has covered. Ia the indication of the shooter on the other hand, a strong clamping effect exerted on the shooter " to overcome them a greater impact force with its disadvantageous consequences is necessary.

Finally, SchütBenbrömsvorric & tungen are known at which, in addition to the normal brake calliper, has a special one Blocking tongue is used, which is on the rear The shooter acts and during the strike from the shooter is lifted. This is now a certain amount of load of the sight already scored at the beginning of the stroke, but beiia the rifle enters the rifle box of? Protect a violent impact on the blockage tongue ", which, in addition to the deficiencies mentioned at the beginning, shows considerable neglect of protecting as well as blocking zongo and with it The consequence of constant change is · Except & em öinct such Braking devices very crinkled in their structure and extremely sensitive in their attitude, so that they are do not work well in practical operation.

The invention is based on the object of eliminating the deficiencies of the known designs and of creating a Schützengbremsvorrichtung simple and reliable in its construction.According to the invention, this happens because the fulcrum of the brake tongue is adjustable and a movement derived from the loom drive inevitably executes in such a way that the rear Ma & d of Breraszunge before and / or is carried away by the shooter during Schut2onscalages in mind © a reduction in the forces acting on the brake pressure · Schiitaen this is compared to the known

Measures with reliable management provide increased relief Protection during the stroke and when running into the hill a perfect blocking of the protection always on the same Position in the shooting box reached »As a result, the blow can be held relatively easily, which in turn less wear of the picker uad Scälsgteil © sur consequence. For the beat and so also for the whole drive of the loom less force is required; and thus the service life of the various parts of the chair, sometimes increased In addition, the now quieter passage of the loom makes the the actual weaving process is improved and both the amount applied Goods also have a favorable influence on their quality.

Zweekmäßigörwelße there is a bromine tongue file from aviei xcat each with its own JÖrehpunkt, wherein the fulcrum of the eiaen parts is calibrated in the other part "Uadurch is Oinoe steadily increasing braking to" Utah standstill dos shadow beia run into the shuttle box he twiddles and q® Oopscuts _t loosening of the weft thread and other defects avoided »The burnout of the scabbard is particularly favored by the fact that an adjustable stop is provided in the area of the free end of the brake tongue to limit the flow of air.

In a further development of the sealing, the brake arm is rotatably mounted on the contactor box by means of an eccentric bearing part * e.g. a bush, a bolt or the like, with the exaeatrical X * agertell executing an inevitable movement derived from the loom.In this way, a very stable movement is obtained «Ad easy to manufacture, adjustable I & gsrtmg 4er Ireaszung ©, with which ordinary brake tongues can be provided without great effort *

The inevitable® movement of the
is preferably over / irkt by moving the crank rod, whereby the movement is transmitted via rods and levers on the drawer or via a linkage with a driver attached to the crank connecting rod and the other arm via a linkage old with the exeentric bearing of the brake lever. This means that the movement of the brake tongue is generated in the shortest possible way and with a minimum of components.

ITacii another Mer & times of the invention let in the Seetiiogft stu? öbertrasuas der Scb. \ d.nsbewegunguns from the crank rod to support the brake tongue, a resilient member is switched on, which serves as a backup in the event of malfunctions and as an equalizer in the event of excessive blows in the transmission tube · W & VHQ3? this makes it possible to take the Scaütaen at blocking brake caliper by hand in ae & Öchutzenkaaten to push or · out of this *

In a further embodiment of the invention, a shaft running parallel to the crank arm is arranged on the Jade, one of which is angled and is connected to a driver on the crank connecting rod, on the shaft itself. another one? Arranged driver solder _t which one is to be verbeßserti actuated under the force of a spring on the eccentric bearing part of EroßB-tongue acting lever "This embodiment is of particular Torteil, ^ ean an existing but insufficient control device & lt of orfindunssgeaassen Bremevoraiichtisns under Belassuag the previous BlocKierungsaatriebs *

Beside that there is aaa © xaentriscften bearing part of the brake tongue, stops are arranged to limit the swing movement of the same. These can be designed in such a way that the brake calliper can be moved by hand at the same time, as mentioned above - is important if the shooter should remove his hand from the contactor box.
