  • Figures 1, 2 and 3 show a side view, a front view and a bottom view respectively of the relay selector, and Figures 4 and 5 enlarged details of the se lecting arrangement of the selector.
  • Figures 6 and 7 show, as already mentioned, a selecting arrangement of another kind in vertical and in horizontal projection respectively entirely and Figure 8' an enlarged detail of said selecting ar rangement.

  • the armature 3 In front of the electromagnet is P sitioned the armature 3 on which is arranged a bifurcated holder I for two bars 5 and 6 secured at opposite sides of the holder.
  • the bar 5 is provided with a plurality oi obliquely cut teeth '1', the shape of which is best seen from the enlargement in Figure t.
  • the bar 6 is provided with a plurality of teeth I" which are shaped in similar manner but are cut obliquely in an opposite direction to that oi the teeth 1.
  • a helical spring it tends to hold the armature I away from the electromagnet 2, the armature then taking up the position shown in Figures 1 to 3.
  • the selector can, however, instead be made direct driven, i. e. so constructed that the armature is held by the spring in the position in which the contact springs are not actuated and is brought to the position shown on the drawings when the electromagnet is energized.
  • current impulses are sent through the winding of I the electromagnet shown in the drawings the armature I is attracted and turns about its pivots Ill, the bars I5 and I then performing a substantially vertical reciprocating movement. Said movement causes a ball 2i resting on one of the teeth II or III" to move along the row of contact groups.
  • the ball Ii is guided laterally by one of the side walls of the aperture in the relay bridge and by a strip 22 of thin metal plate which serves as a partition wall between the anterior and the rear feeding paths in which the ball 2
  • Figure also shows how the ball is transferred from the rear feeding path to the anterior one.
  • the last tooth 23 is cut obliquely in such a manner that the ball during its movement downwards will move in a path which is perpendicular to the preceding path the ball then getting into engaging position for the anterior feeding bar 6.
  • the ball is stepped forward in the same manner as described above for the rear path.
  • tact groups are actuated the othr ball will be restored in the feeding path in which no contact groups are actuated, the two balls simultaneously changing feeding paths.
  • Two or more balls can also operate in such a manner that both simul- 'taneously actuate contact groups which are displaced certain steps from each other, for example the first, the sixth, the eleventh group, cto, whereby a greater number of contact springs can be actuated simultaneously.
  • Another manner of restoring the ball from the last contact to the first contact in the same feeding path is to use only one feeding path according to the above sadness description and a particular restoring path extending between the end points or the feeding path, said restoring path consisting either oi an empty somewhat sloping groove or channel or of a tube filled with balls lying side by side.
  • the ball is simply permitted to roll along the sloping channel back to its start ing point.

  • the contact actuating member i. e. the ball 2i can itself constitute a contact closing member, the relay selector in its entirety with the exception of the insulated contact springs being then supplied with, for instance, earth potential.
  • the ball is permitted to actuate the contact springs directly and Will, during the operation of the selector, itself connect earth potential to the springs in due order then forming itself a part or the electric circuit.
  • the contact actuating member it is not necessary to shape the contact actuating member as a ball; it can be given other desired shapes, for instance cylinder shape, provided that the feeding path is shaped accordin'gly.
  • the contact actuating member can also be rotatably journalled about a certain point.
  • An example is represented by the selecting arrangement shown in Figures 8 to 8 where the contact actuating member consists of an arm arranged on a rotatable shaft.
  • said selecting arrangement are included two stationary cylindrical rings 25, the upper and lower sides of which are toothed in the manner illustrated in Figure 8, in two diametrically extending small bars ill and is rotatabiy journalled a vertical shaft iii. in said shaft is arranged a contact arm to which normally rests on the lower ring 25 and which is pressed thereagainst with a light spring pressure by a small spring iii.
  • the driving member liits against a slight coun ter pressure from the'spring it the shaft 2t and the contact arm so mounted thereon.
  • the contact arm After the contact arm has been lifted a predetermined distance it strikes against a tooth on the upper ring iii-the position ii". iniigure B-and is turned during its continued upward movement together with the shaft 28 about the geometrical axes of the latter until it reaches position L.
  • the contact arm makes contact with a pair of the fixed contacts 33, and, if the arm is made of electrically conducting material, a circuit can then be closed through the contact arm and the tvvo fixed con tacts.
  • the contact arm 30 When the driving member 32 again moves downwards the contact arm 30 is displaced downwards on account of its own weight and the pressure from the spring ii to position M and then slides along a tooth on the ring 25 to position lid. The contact has thus been moved from one tooth on the ring to the next one. Upon receipt of the next current impulse the cycle is repeated, the contact turning from one contact 32 to the other during the up and down movement of the driving member.
  • the contact arm can of course be constructed in several difierent Ways, for example be one-armed, multiermed, insulated, etc., ways on which it is not necessary to enter more closely in this connec tlon. l
  • this operation can be obtained for in stance by selecting such a distance between the contact 3t) and the contact 33 that no contact closing takes place during selection but first after selection been completed, another member, for instance an electromagnet armature in the shape of a ring positioned under the con-- tact arm inside tl'ie rings 25 and then lifting the contact arm till a further distance thereby pressing it against the contact 33.
