Definitions

  • One of the objects of the'present invention is to provide a relay wherein any one of the stationary or movable springs may be removed and replaced without disturbing any other spring.
  • Another object of the invention is to provide a relay wherein the springs are kept in alignment at the mounting, plate end and also at'the operating end.
  • Another object is to provide a relay in which the spacing between the movable and stationary springs is determined by notches in insulating combs, one comb for this purpose serves as the spool head at the mounting end and another notched comb being mounted at the opposite or operating end of the core and a third comb, parallel to the first two, being fixed between the armature and the armature restoring spring,
  • Another object of this invention is to provide a relay in which adjustments of contact springs have been eliminatedentirely or at least reduced to a minimum, there being only two principal adjustments, tensioning of the main or armature restoring spring and the armature back stop.
  • Still another object of this invention is to so arrange the notched insulating comb at the mounting end, that any notch may be occupied by a make, a break or amovable spring.
  • Figure 2 is a bottom view of a relay showing the armature, the armature mounting spring and the off-set section of the movable springs, to provide clearance for the up and down movement of these springs without interference with the stationary springs.
  • Figure 3 is an end view taken from the right of Figure 2 looking toward the operating or contact end of the relay showing, in particular, the notched comb which is-movable'with-the armature and which carries with 'it, the movable springs.
  • Figure 4 shows the outline of a movable spring, indicating the off-set feature.
  • Figure 5 shows an outline of a stationary spring indicating the off-set feature.
  • Figure 8 is a view of a part of a spring pile-up to show the ease with which any spring may be replaced without disturbing any other spring.
  • Figure 3 is an end view of the relay showing the relative positions of the combs 6
  • the notches for the springs are of uniform spacing and therefore maintain all springs in correct relation with each other without pro-tensioning in the ordinary meaning of the term.
  • the notches in the combs are so arranged that either a movable or a stationary spring may occupy any spring position. This feature allows a great variety of contact combinations to be assembled while using a single type of comb arrangement and also it provides for alterations to be made at any time, with ease and dispatch.
  • Figures 4 and 5 show the outline of the movable and stationary springs respectively. Particular attention is directed to the cut-away portions 42 and 52, forming shoulders which fit over one edge of insulator 82 and the inside edge of the notches, such as notches 83 to prevent any end to end movement of the springs after being assembled in the spring pile-up.
  • the movable springs are usually equipped ,with two precious metal contacts, not shown.
  • are split for a short distance from the free end and one metal contact is provided on each leg thus formed.
  • Figure 8 is an exploded view of a part of a spring assembly to illustrate the ease with which a spring or springs may be removed or replaced Without disturbing an other spring.
  • Item represents the magnetic pole piece which fits snugly on the coil core, not shown, and adjacent to the insulating comb member 84, which is also fitted to the core and slightly larger than element 80.
  • the non-magnetic member 24 is first assembled on top of element 89 followed by the insulating member 82 with its unnotched edge resting againstinsulator 84 and with its screw holes 85 lined up with the threaded holes 81 in the magnetic pole piece-80.
  • a first fixed insulator parallel slots in said first insulator, a plurality of fiat stationary and movable contact springs, the base ends of said stationar and movable contact springs inserted in said slots and their fiat surfaces arranged in superimposed relation in a single alined and superimposed pile-up
  • a second fixed insulator spaced a predetermined distance from said first insulator, corresponding parallel slots in said second insulator in which only the stationary contact springs at a point near their free ends are inserted for positioning the free ends of said stationary contact springs
  • a coil core and coil positioned between said first and second insulators, said coil core being substantially in axial alinement with said contact springs
  • a movable third insulator spaced near said second insulator, corresponding parallel slots in said third insulator in which Only the movable contact springs at a point near their free ends are inserted for normally positioning the free ends of said movable contact springs and for operating said movable contact springs to
  • circuit controlling device as claimed in claim 1 including a curved portion on each of said movable contact springs for by-passing said second insulator to prevent said fixed second insulator from interfering with the movement of said movable contact springs.
  • a core In a relay, a core, a coil winding on said core, a first and a second insulating spool head attached to the ends of said core for confining said winding, a plurality of stationary and movable contact springs, a plurality of slots in the first of said spool heads in which the base ends of said stationary and movable contact springs are assembled for arranging said contact springs in superimposed relation with each other in a superimposed contact spring pile-up, a plurality of slots in the second of said spool heads in which the free ends of said stationary contact springs are assembled for maintaining said stationary contact springs in their assembled positions, an insulator, a plurality of slots in said insulator in which the free ends of said movable contact springs are assembled for maintaining said movable contact springs in their assembled positions, an insulating plate mounted over said slots and contact springs in said first spool head to retain said contact springs assembled in said slots, said plate being removable to permit removal and replacement of any of said contact springs without
