Definitions

  • This invention relates to electromagnetic re-' lays and more particularly to relays of high speed and sensitivity that may be adjusted to operate within very close limits of the desired sensitivity.
  • Inelectrical control circuits generally and in business machines, particularly, it is often essential'to have a relay that operates reliably and quickly at a certain minimum current.
  • An object of the invention is to provide a relay that may be adjusted in sensitivity without affecting the contact adjustment.
  • Another object is to produce an inexpensive relay of small size and simple construction havin an armature and winding which may be manual- 1y assembled thereto or dismounted without the aid of tools.
  • the relay comprises a V-shaped yoke or bracket which may be permanently attached to a, suitable supporting framework.
  • the polepiece extends outwardly from the base of the yoke between the arms thereof.
  • a spool carrying the relay windings is adapted to be slipped over the polepiece, either before or after the yoke is attached to its support.
  • the spool. is removably secured to the structure by a spring clip fastened to one arm of the yoke. prises a flat piece of magnetic material, one edge being a knife-edge which rests in a complementary V-shaped groove in one arm of the yoke where it is held in position by a, bowed, approximately J-shaped spring formed from flat stock.
  • the spring is self retaining when in operating position, one end being held by spring pressure in a notch or recess in a flat conducting member attached to the armature but insulated therefrom while the opposite end of the spring is held by spring pressure in an opening in an adjustably tensioned flat spring attached to the opposite arm of the yoke but insulated therefrom.
  • the spring arrangement exerts pressure on the armature efi'ective to retain it in the V-shaped groove as well as tending to bias the armature away The armature cornfrom the polepiece.
  • the spring arrangement provides a circuit connection for a contact tongue attached to the armature, but insulated therefrom, to eliminate carrying current through the armature pivot which would ultimately result in erosion of the knife edge and groove.
  • the J-shaped spring is easily removed by flexing the same between the thumb and fingers to disengage the ends thereof from their supports.
  • the armature then may be lifted out of the V-shaped groove and the spool carrying the winding may be slipped off the polepiece after withdrawing the spring retaining clip from engagement therewith.
  • Fig. l is an isometric view of the relay
  • Fig. 2 is a side elevation of the relay with the tensioning spring partially broken away to show the contacts more clearly;
  • Fig. 3 is a top view of Fig. 2;
  • Fig. 4 ' is a front end view from the right hand side of Fig. 2;
  • Fig. 5 isa vertical section taken along the lines 55 of Fig. 4;
  • Fig. 6 is an exploded isometric view of the relay.
  • Fig. 7 is an enlarged detail view of the pivot for the armature.
  • the-relay comprises a generally U-shaped yoke or frame I I, the upper arm 24 thereof being slightly shorter than the lower arm 4.
  • the yoke is adapted to be permanently secured at its rear to a suitable supmantled from the front end of the yoke making it unnecessary to disturb the yoke when once mounted.
  • a polepiece III may be permanently secured to the yoke and extends outwardly between the arms thereof.
  • a slot 5 is formed in the lower arm I of the yoke to recieve a lug B Fig. 6, formed on one end of a spool l on which .the relay coil 12 is wound.
  • the spool is adapted to be slipped over the core or polepiece ID, the lug 6 being proportioned to fit into and be guided by the slot 5 which restrains the spool from turning on the polepiece.
  • a flat spring 8 is fastened at one end by a screw to the under surface of arm v4 of the yoke and a catch I3 on the spring extends normally into slot 5 where the catch engages the outer surface of the lug 8 when the spool is pushed back snugly against the yoke.
  • the catch holds the spool firmly on the polepiece.
  • the outer end of spring 8 beyond the catch I3, is slightly bent away from the arm of the yoke so that the spring may be depressed away from the yoke arm, for example, by a thumb nail, to withdraw the catch I3 from the slot 5 to free the spool for removal.
  • a V -shaped groove I6 is formed in the upper surface of the yoke arm 4 near the outer end thereof and extends across the slot 5.
  • An armature I4 comprising a fiat piece of magnetic metal has a knife edge I5 formed on the lower end thereof which rests in the V-shaped' groove I6.
  • Pins H are disposed in the groove at opposite sides of the armature and slightly spaced therefrom to prevent lateral movement of the armature in the groove.
  • Contacts I8 fixed to the upper end of the contact tongue cooperate with spaced stationary contact points and 2I set on depending portions of contact springs 22 and 23, mounted on arm 24 of yoke II b screws 25 and insulated from the yoke by insulators 26.
  • An adjustably tensioned leaf spring 21 is mounted on arm 24 by screws 28 but insulated therefrom.
  • spring 21 serves as a lug to which external connections for the armature may be soldered.
  • the opposite end of the spring 21 extends beyond the yoke arm 24 and has a hole 3
  • Connection is made between spring 21 and the armature by a bowed approximately J-shaped spring 30 formed from flat spring metal. Near its upper end, the spring 30 is cut away on opposite sides forming a narrowed portion which fits in the hole 3
  • the opposite end of spring 30 is formed into a small reverse hook 32, Fig.
  • the armature I4, the spring 30, and the tensionarmature I4 is then easily removed by lifting the same out of its bearing groove.
  • the catch 13 is pulled out of engagement with lug or extension 6 and the coil I2 then slips off the core I0 readily.
  • the coil I2 is replaced on the core Ill.
  • the catch I3 is allowed to snap back into position.
  • the knife edge I5 of the armature I4 is inserted into the V-shaped groove i6 between the pins H with the contact I8 between the contacts 20 and 2 I.
  • the lower hooked end 32 of the spring 30 is then nested in the notch 33 in the upper end of the armature I4 and the Making the springs 21 and 30 of con *4 upper end of the spring 30 is then inserted in the hole SI in the tension leaf spring 21.
  • a supporting structure having a polepiece mounted thereon and a groove near one end of the supporting structure; a coil slidably mountable on said polepiece; a clip on said supporting structure for locking the coil on said pole-piece; a contact supported on said structure; an armature attractable to said polepiece and having a contact thereon cooperable with said contact supported on said structure, the said armature having a pivot edge for pivoting in the groove on said supporting ,structure; and a curved spring detachably'engaging the armature and coupled with the supporting structure for biasing said armature, the s/aid spring being also utilized for conducting current into the armature contact and for holding said armature in the groove.
  • a relay adapted to be assembled and dismantled easily comprising an approximately U-shaped yoke, a polepiece permanently secured to the rear of the yoke extending outwardly between the arms thereof, the yoke having a V- shaped groove formed across the inner surface of one of its arms beyond the end of the polepiece, a readily removable or replaceable armature formed of a fiat piece of magnetic material having a knife edge resting in the V-shaped groove, a metal member including a contact tongue formed with a notch therein secured to the armature, the notch being disposed opposite the knife edge, a sprin member mounted on the opposite arm of the yoke formed with a recess approximately overlying the notch of the metal member, and a bowed spring member detachably engaging the notch with one end and the recess with the other, the spring being so tensioned and dimensioned as to bias the armature as well as holding it in place in the V-shaped groove, while being held in place solely by
