Definitions

  • her of relays may be employed in accordance with the accounting requirements of the machine user, and it is necessary that the relays, where they are added -to the accounting machine, be quickly installed and easily maintained. Accordingly, it is proposed to install in an accounting machine a panel or panels on which the maximum number of relays, which it is beieved the user can ultimately employ, may be mounted and to attach to the panel only such relays as are required to fulfill the user's present needs.
  • the panel is provided with jacks constituting the terminals of the internal wiring of the machine and the relays are provided with plugs, so that in order to add a further relay it is only necessary to plug in the relay in the proper position of the panel.
  • the relay s arranged to be held in place by spring clips, and to replace a damaged or worn relay it is simply a matter of pulling out the old and inserting a new one.
  • Fig. 1 is a side elevation of a relay in position against a jack panel of the machine.
  • Fig. 2 is a detail of one of the panel jacks.
  • Fig. 4 is a sectional view of therelay showing the parts in operated position.
  • Fig. 5 is a detail of one of the contact wires.
  • Fig. 6 is a view of a modified form of the relay.
  • Fig. 1 It represents the part of the framework of an electrical accounting machine for use in connection with which the re- ?ays are especially adapted.
  • an L-shaped plate l3 Near the upper end of each panel is an L-shaped plate l3 provided with side arms I embracing an extension Ila of the panel, the plate I 3 being secured to the panel by the bolt I2.
  • jacks l5 Embedded in the panel are a number of jacks l5, one of which is shown in isometric in Fig. 2. From the left side, these jacks are connected to the various mechanisms of the accounting machine by means of plug' wires such as indicated at I6, and each jack is provided with a double plugging position for possible multiple connection.
  • the relay itself is contained in a U-shaped frame ll of insulating material which is provided with a pair of grooves l8 located so as to be engaged by resilient arms I! of the plate l3 (see Fig. 3).
  • a U-shaped frame ll of insulating material which is provided with a pair of grooves l8 located so as to be engaged by resilient arms I! of the plate l3 (see Fig. 3).
  • the yoke to which is welded the core 2
  • a bracket 24 Between the upper surface of the yoke and the frame is a bracket 24 provided with side arms 25 which serve to support the armature pivot pin 26 loosely mounted in the side arms.
  • Armature 21 is hooked at its upper end to partially encircle pin 26 and has riveted thereto a leaf spring 28 which engages a flat section of the-pin.
  • a leaf spring 28 which engages a flat section of the-pin.
  • a thin residual element 29 which extends around the left edge of the yoke and also has a resilient extension 30 bowed to engage the loweredge of the armature 21.
  • the extension 30 is biased upwardly so that, when the armature is attracted, the extension will spring upwardly as in Fig. 4 and serve to prevent any possible bounce" or chatter.
  • the face of the core is arranged in precise alignment with the ends of the yoke, so that the thickness of the residual element provides the necessary air gap and in assembling the parts the" residual element is clamped in place by the lower screw 23, while the bracket 24 is similarly clamped in position by the upper screw 23.
  • the upper end of this wire is hooked as shown in Figs. 1 and 3 with the hook extending through a hole 26 in a plate 31.
  • Plate 31 is positioned on the top of the frame I! and held thereto by the upper screw 23.
  • the plate is provided with an elongated hole 39, so that before the screw 23 is tightened the plate 31 may be moved to the left or right to decrease or increase the pressure against the upper end of the wire 35.
  • the lower or free end thereof With the plate 31 bearing against the left side of the wire and the side of opening 33 in contactor 3
  • the wire 35 also serves to conduct current between the contactors 3
  • Riveted to armature 21 is an angle 401 of insulating material which is provided with a suitable opening through which the wire 35 extends and through which the wire, by virtue of its adjusted tension, serves to normally hold the armature 21 in position as in Fig. 1.
  • the relay may include a number of wires 35 spaced as shown and for each such wire there is provided a set of contactors in line therewith. The left ends of the several contactors extend from the frame l1, so that when the relay frame I1 is snapped into position as shown, the contactors engage the companion jacks H as shown.
  • the wire 35 is, in effect, suspended within the relay with no special mechanism to holdit in place other than the pressure exerted against it on one side by contactor 3
  • the armature itself may be separated from its bracket 24 by simply flexing the blade spring 28 and sliding the pin 26 axially through the side arms 25. When it is desired to replace the entire relay, it is simply necessary to grasp the frame l1 and draw it away from panel I I.
  • Fig. 6 a modified form of the invention wherein the wire spring 50 is U-shaped and extended through holes in a plate 52 with one leg passing through an opening in insulating element 53 and the other leg anchored by passing the same through a hole in the contactor 54.
  • the upper leg of the wire is normally biased to bear downwardly on the armature 55. In this case replacement of the wire is simplya matter of grasping the same at the right end as viewed in Fig. 6 and drawing it out of engagement with the element 53 and contactor 34.
  • an armature, a core, a yoke for said core having a face thereof in alignment with the face of the core, said armature being pivoted to align with the face of the core and yoke, a residual element covering said yoke face to space the armature from the core face, said element having a resilient extension forming a 'detent, in engagement with the free end of the armature constructed to yieldably oppose its restoration to prevent vibration core, said spring member being freely insertible' through all three openings whereby one side of the central opening will bear against the spring member and cause the member to bear against the opposite sides of the other two openings to urge the armature away from its core, the movement of said armature being limited to obviate full alignment of all three openings.
  • the spring member comprises a strand of spring wire having a bend therein at one of the openings, said bend engaging the edges of the openfl' ing to prevent inadvertent displacement of the wire.
  • a multicontact relay a coil, an armature and a support therefor, a plurality of freely removable wire springs arranged in parallel alignment, an adjustable member carried by said support, one end of each of said wires being pivoted on said member and the opposite ends of all being engaged with said armature, and means bearing against each of the wires at a point intermediate the ends of each to tension the same and thereby swing the armature away from the coil, said member being adjustable to vary the pivot points of all of the springs concurrently.
