Definitions

  • the present invention relates to switche con-j trolled by bars actuated in various combinations
  • code bar switches which can- ⁇ be used, for instance, in telephone systems. Its object is to realize a switch of this type occup ing the minimum amount of space which is allowed for a satisfactory performance and utilizing economical, reliable and easily manufactured components.
  • a featured the invention resides in a code bar switch comprising a set of parallel code bars and a set of selection levers, the latter arranged perpendicularlyto the former and such that they can pivot about a line perpendicular to the code bars.
  • each selection lever comprises two main parts, both perpendicular to the code bars, the first being pivoted at both ends in a fixed part,
  • second being made integral with the first by means of a bridged part, and being provided at both ends with two actuating arms which may actuate any desired mechanism such, for instance, as a two-position device.
  • each of said selection levers'lincluding said'bridged part can be cut from i fiat plate and that they have all the same shape and dimensionsgfsaid arms pertaining to said bridged part being bent perpendicularly to said flat plate either in one sense or in the other, in order to obtain two kinds of selection'levers which can be intermeshed so as to. limit the space occupied by the complete arrangement.
  • each code-bar can occupy is denoted by p, the
  • Fig. 1 a plan view of the code bar arrangement
  • FIG. 2 a side view of Fig. 1;
  • FIG. 3 a cross-sectional side view of Fig. 1 along the line :ca:;
  • Fig. 4 a cross-sectional side view of Fig. 1 along the line :c-x, a particular combination of code bars having been actuated resulting in the operation of a particular lever;
  • Fig. 5 a cross-sectional end view of Fig. 1, along the line y-y';
  • Fig. 6 a cross-sectional end view of the line z--z.
  • the code bar arrangement which is shown in the variou figures utilizes'five code bars which can each occupy two different positions in accordance with the electrical condition of the magnet (not shown) controlling each code bar. Accordingly, thirty-two combinations are possible and a number of selection levers equal to or less than thirty-two can be used.
  • a frame I having a U- shaped cross section is shown.
  • the bottom part of the frame I is out along a line perpendicular to its length and also along two lines parallel to its length along both vertical sides, in order to obtain a small rectangular part such as 2 which can be bent upwards along a plane perpendiculartothe bottom part of the frame.
  • This rectangular part is provided with a series of five slots such as 3, l.
  • H and i2 is provided with a series of slots 14 38 such as l3, the-shap f which can be seen more clearly on Figs. 3 and 4..
  • These slots such as it have substantially the shape of aright angle trapezium.
  • a series of selection levers such as 39 are. pie-. 1 ,1 vided, each comprising two parts such asst and" M which are both perpendicular to the: code bar.
  • the ends of the part or the selection lever 39 have been provided with.
  • two lugs-55, and 57 .ivhich are 'inserted'in small rectangular openings provided in the vertical .sides. ofthe.-'L-shaped pieces 53 and 5%.
  • 'Slots such as 58 andlillhave also been cut in the vertical-sides oi. the frames! to permit the insertion ofzthe lugsv 56. and 5T. It. will beiappl-eciatedthat the leyers'suchias '35; are '50 shaped and so designed-that. they can be intermeshed between one another in a: horizon- .tal'plane so toiuse a minimumamount of space.
  • this shows the manner inpwhichthe various Scode. bars are further guided along their le th;- Due. to the interleaving of the arms such as it and 43 between the various code bars and the vertical sides of the frame i, it is not possible to provide a guiding bent piece such as 2 at intermediate points along the length of the code bars.
  • a guiding bent piece such as 2 at intermediate points along the length of the code bars.
  • prongs such as 59 and ill have been cut in the bottom part of the frame i and bent upwards in a vertical plane.
  • a second set of prongs such as 7!, i2, 73 and '54 have also been cut and bent in a similar manner but are aligned at a certain distance from the first two prongs 89 and Iii. This staggering permits the insertion of the arms such as 42 and 43 pertaining to the selection levers (not shown) which immediately follow selection lever 63.
  • code bar 8 is guided between prong 69 and prong 1!
  • code bar 9 is guided between prong H and prong it etc.
  • Pins i5 and 16 located perpendicularly to the various code bars are used to support them.
  • Code bar mechanism comprising a fixed frame member, a plurality of spaced parallel code bars arranged for displacement in a certain plane, a plurality of selection levers cooperatively associated with said code bars, each of said levers comprising two separated main portions, each portion being perpendicular to said code bars, one of said portions being pivotally mounted on said frame member, the other of said portions having a first part adapted to cooperate with said code bars, bridging means for connecting both of portions to ether, each of said means extending substantially parallel with and interleaved among said code bars, each of said means in staggered relationship with the other, whereby to permit close disposition of said selection levers, each of said other portions having an actuation part.
  • Code bar mechanism comprising a fixed frame member, a plurality of parallel code bars arranged for relative parallel displacement. a plurality of selection levers each of said selection levers comprising a portion arran ed for pivotal movement about an axis substantially perpendicular to said code bars and parallel to the plane of movement thereof and a second portion spaced from said first portion by a distance suflicient to accommodate a first portion of a second lever and a second portion of a third lever therebetween, means bridging said portions to permit said secend portion to pivot about said axis each of said bridging means extending substantially parallel with and between clifierent of said code bars, said second portion including means cooperating with said code bars to permit movement of said second portion about said axis in accordance with a predetermined positional relationship among said code bars, and biasing means for biasing said last named means into cooperational relationship with said code bars.
  • a plurality of levers arranged for selective operation in accordance with predetermined positional relationship between said code bars, eac.
