  • the exemplary embodiments of apparatus depicted in FIGS. I to 7 will be understood to each comprise and electromagnet 2 which is mounted at a schematically depicted holding or holder mechanism I.
  • the nonvisible coil of each such electromagnet 2 is selectively connected via two coil terminals 3 with a not particularly illustrated suitable voltage source. Excitation of each electromagnet 2 occurs in accordance with a control program.
  • the armature 4 ofthe electromagnet 2 is constructed as a retaining or holding hook member or element which is pivotably mounted about an axle or shaft 5 at the holding or holder device I.
  • a resilient element. such as the spring 6 engages with the armature 4. this spring 6 being secured at one end to the holding mechanism or device I. as shown.
  • Spring 6 moves the armature 4. when the electromagnets are not energized. out of a first position where it bears against the associated electromagnet 2, as best seen by referring to FIGS. I. 3 and 5, into a second position. as best seen by referring to FIGS. 2. 4 and 6. where it engages with a recess 7a of a control element 7 and fixedly holds the latter in a first terminal or end position.
  • This control element 7 is driven to-andtro in synchronism or cycle with a textile machine and between two terminal positions in any suitable manner.
  • the second terminal position of the control element 7 has been indicated in phantom lines.
  • This control element 7 can serve. for instance. to actuate a yarn guide device of a textile machine. as the same has been described in German patent application P 22 ()4 814 incorporated herein by reference.
  • the armature 4 is provided with a nose or dog mem ber 4a with which cooperates an actuation de ⁇ ice. which for the exemplary embodiments depicted in FIGS. 1 and 2. 3 and 4 as well as S to 7 respectively. is differently constructed.
  • this actuation device or mechanism incorporates a lever 8 which is rotatably mounted at one end about a shaft or axle l0 and at its other end is supported through the agency of a spring II at the holding mechanism or device 1.
  • a roller or roll 12 which cooperates with a rotatably driven control disk or cam I3.
  • the spring I1 there is achieved the result that the roller 12 will bear against the control cam surface of the control cam 13.
  • this lever 8 carries an actuation ledge member or rail 9 which acts upon the nose or dog 41:.
  • the control cam 13 rotates in accordance with the movement ofthe control element 7 in cycle or synchronism with the textile machine. If. as shown in FIG. 1. the roller 12 cooperates with the protruding portion 13a of the control cam I3, then the lever 8 is raised and rotated into a position in which the actuation ledge or rail 9 acting upon the nose or dog 4a presses the armature 4 against the electromagnct 2 FIG. I J. During further rotation of the control cam or disk I3 the lever 8 is downwardly pressed by the spring II and the actuation ledge 9 rotates in clockwise direction out of the position depicted in FIG. I into the position illustrated in FIG. 2. If at this point in time the electromagnet 2 is not energized.
  • the spring 6 pulls the armature 4 into its position where it has dropped or moved away from the electromagnet 2. and which has been shown in FIG. 2. In this position the armature 4 engages with the control element 7 which. at this point in time. is located in its lower end or terminal position and fixedly retains this control element in such terminal position IFIG. 2).
  • the actuation mechanism analogous to the embodiment depicted and described above with regard to FIGS. I and 2, possesses an actuation lever 8 which is rotatable about a shaft or axle 10, this lever 8 hearing at one end through the agency of a spring 11 at the holding or holder mechanism 1.
  • a roller 12 At the lever 8 there is again rotatably mounted a roller 12 which is pressed by spring 11 against the control cam surface or curve of the control disk or control cam 13 which is rotatably driven in synchronism or cycle with the textile machine.
  • actuation ledge or rail member i.e.. an actuation member 14.
  • This actuation ledge or rail member 14 analogous to the actuation ledge or rail member 9 of FIGS. 1 and 2, acts upon the nose or dog member 4a of the armature 4.
  • the armature 4 If the armature 4 is located in a position where it has dropped-off or moved away from the electromagnet 2 (FIG. 4]. then it blocks the control element 7 located in its lower terminal or end position. In this position the armature 4 is held by the spring 6. Ifthe electromagnet 2 is energized. then such attracts the armature 4. so that this arntaturc. as best shown by referring to FIG. 3. comes to bear against the electromagnet.
  • I4 is constructed in such a way that the actuation ledge member I4 then pushes against the nose when the armature 4 bears against the electromagnet 5 2. Since this electromagnet 2. at this point in time, is not energized. the armature 4 is pushed away from the electromagnet by means ofthe actuation ledge member 14 and is rotated by the spring 6 into the position depicted in FIG. 4.
  • the armature 4 is located in the one or other position and blocks the associated control ele ment 7 or does not influence such control element respcctively.
  • the pushing away fo the armature 4 from the nonenergized electromagnet 2 by means of the actuation ledge or rail member 14 is particularly of significance in the case of direct-current magnets, since the armature, after de-energizing the excitation coil of the elec tromagnet, remains adhering at the electromagnet owing to remanence. Now in order to avoid erroneous actuation brought about by the undesired adherence of the armature 4, this armature is raised or moved from the electromagnet when the latter is not energized by means of the actuation ledge or rail member 14.
  • the actuation mechanism is constructed as a combination of the actuation mechanisms of FIGS. 1 and 2 and that of FIGS. 3 and 4.
  • the actuation lever 8 which bears at one end via a spring II at the holding mechanism or device 1 is rotatably mounted at its other end about the shaft or axle 10 and at this end possesses two actuation ledge or rail members i.e.. actuation members 9 and 14. These members accommodate therebetween the nose or dog 41:. upon which they act depending upon the position of the lever 8.
  • the position of the actuation lever 8 is determined by the control cam or disk 13 which is rotatably driven in synchronism with the textile machine, this control cam 13 cooperating with a roller 12 which is rotatably secured at the lever 8.
  • FIG. 5 illustrates the armature 4 in its position where it bears against the electromagnet 2, and in which position the armature 4 is moved by the actuation ledge member or rail member 9 which acts upon the nose 4a.
  • the lever 8 is located in its raised position in which it is rotated by means ofthe protruding portion 13a of the control cam 13.
  • FIG. 8 illustrates a different exemplary embodiment of the invention apparatus.
  • An clectromagnet I6 is attached to a holding device or mechanism IS.
  • the armature 17 of the electromagnct is constructed to possess a substantially plate-shaped configuration and carries a plunger 18 which is displaceably guided in the holder or holding mechanism I5.
  • a spring [9 which is attached to the holding mechanism 15. This spring I9 strives to pull the plunger I8 together with the armature plate 17 away from the electromagnet.
  • a nose or dog member I811 which engages in a groove 20a of an actuation lever 20 which is guided in the holding or holder mechanism IS.
  • the groove 20 is bounded or delimited by two stops 20b and 200 which act upon the nose or dog I811.
  • the actuation lever or lever member 20 is supported at one end at a spring 21. At the other or opposite end this lever 20 carries a roller 22 which is urged by the spring 21 against the control cam surface of a control cam or disk 23 which is rotatably driven in cycle or synchronism with the textile machine.
  • FIG. 8 operates in the same manner as the apparatus depicted in FIGS. 5 to 7.
  • the actuation lever 20 and also the plunger I8 are shifted until assuming the phantom line depicted position. in which the plunger blocks the previously mentioned. although not here particularly illustrated. control element in its one terminal position. as such has been described in conjunction with the embodiments of FIGS. I to 7.
  • the plunger 20 at its end in such a way that it blocks the control element in its one terminal position when the armature I7 bears against the electromagnet I6 and in the dropped-off or shifted away position of the armature I7. which has been shown in phantom lines. the movement of the control element is not influenced.
  • the one or the other of the stops or im' pact members 20/] and 20( can be omitted at the actuation lever 20 in order to only bring about a lifting-off or a contact i.e.. pressing-on of the armature 17.
  • the holding element which is constructed as the armature of the clectromagnet selectively blocks the control element. for instance a notched bar. in one terminal position.
  • the armature is moved against the elcctormag net and/or raised-off the dc-energized electromagnet.
