More particularly, the invention provides novel means for the selection andoperationof the-soecalled vertical bars which are used in multi-switches ofthe crossbar type.
  • An object of the invention resides in a selecting andI controlling mechanism for movable parts, each of said part or partsbeing under the control of clutch means which are themselves controlled by selectionA means, the actuation of these selection means havingy the ei'lect oi lcausing the displacement of'v said clutch means associated therewith' in order to place said clutch means under the control ofl common control means?, which; when actuated, drives by means of said clutch means, the selected movable part or partswhich are' associated therewith;
  • a :further object of the invention' resides in theffact that the selection means comprise a plu:- ralityiof code-bars'suchv as disclosed in the Belgian Patent No. 4243561* whichA canbey actuated in a plurality of different combinations, each particular combination resulting inthe operation of one particular selection lever correspondin'gto that particular combination, whichl will in4 turn actuate the clutchmeans.
  • a feature of the inventionL resides. in clutch means which arev constituted byl a small independent member guided in Xed parts and ⁇ which isnormally under the control of a selection lever, which; when actuated, will'place said independent'clutbh'member'under'the control of common control means. y
  • Another feature of theinvention resides in an intermediatelever mechanically related to a corresponding movable part and'which will bev actuated bysaid common control meansl by means of ⁇ saidindependent' clutch member.
  • Another feature of the invention resides in the provision of a rst channel in which said ball is guided when it' is displaced under the controlv of the selection lever and of a second channel, perpendicular to-the rst, in which said ball is guided when itis ⁇ further displaced under the controler the common control bar.
  • a'- iixed part comprising a central plate fixed perpendicularly to mainbase-plate; and' two' profiledparts having a U-shaped crosssection-fixed by one ofv their iaces cnboth sides of said cen'- tral plate, the three adjacent central sides belonging' to the centrali plate and to both profiled parts being provided.
  • Another ifeatureof the invention resides-inthe displacement of said common control bar along its main plane and perpendicularly to its longitudinal edges.
  • Another feature of the invention residesin the fact that said selection lever is directly actuated by saidicode bars.
  • each offsaid-selection levers is provided with two actuating arms located on both sides of the code bars and that two common control'bars are also providedon bothsides of the code bars, whereby by utilizing twolintermediate leversv symmetrically located on both sides of the codebarsforf each of saidselection levers,- an arrangement for the actuationoftwo movable parts Willbe provided which will occupyA aminimum amount' ofspace.
  • Fig. 1 represents a perspective view of the arrangement, parts having been cutaway in order ⁇ to show more clearly some of the mechanical details
  • Fig. 2 represents a cross-sectional side view of the mechanism in its normal position
  • Fig. 3 represents a cross-sectional side view of the mechanism in its clutch position
  • Fig. 4 represents a cross-sectional side view of the mechanism in its actuated position
  • Fig. 5 represents a perspective view of part of the code bar arrangement Yincluding a selection lever the code bars and selection lever turned upside down.
  • This selecting and controlling mechanism may be adapted to the selection and control of the vertical movable bars pertaining to the arrangement described in my U. S. Patent No. 2,589,267, granted on March 18, 1952.
  • the arrangement comprises a set of two vertical bars I and I which can be actuated by their respective intermediate levers 2 and 2' and which are operatively positioned in a iirst plane and only the lirst of which being completely shown.
  • a set of iive code bars 3, d, 3, 6 and 'I, operatively positioned for movement in a second plane, has been partially shown together with a single selection lever 3 corresponding to the two intermediate levers 2 and 2.
  • a periodically-operated common control bar 3 has also been partially shown with two of its teeth I and I located along one of its longitudinal edges.
  • the selection lever B is hinged in two ilxed pieces 'I and Il', only the rst of which I'I, being shown on Fig, 1. are provided with a small rectangular opening such as I3 in which lugs I9 and I9' provided at both ends of lthe arm of the selection lever 3 are inserted. Accordingly, the openings such as I8 will provide fulcrums for the selection lever 8.
  • the selection lever 8 will thus rotate about its fulcrums such as I8 and in so doing 'will lift the ball I I which is normally resting on the bent end 2'I of the arm i2 of the selection lever 8.
  • the complete mechanism is nxed to a main base plate 28 by means'of a U-shaped part 2S, the two vertical branches of which 33 and 3G are spaced suiciently apart in order to provide room for the code bar arrangement and the selection levers such as 8, as well as the intermediate levers such as 2.
  • On each face of the vertical branches such as 3U are xed two proved parts such as 3l and 32.
  • the proled parts SI, SI and 32, 32' have also a U-shaped cross section but the distance between both branches is much smaller so as to aord guidance for the ball I I.
  • the external branch of the profiled part 3I is provided with a small opening 33 in which the grooved end 32 of the tooth I3 can be inserted.
  • the external 'branch of the proled part 32 is provided with an elongated slot 35 in which the arm 36 of the intermediate lever 2 can be inserted.
  • the interna1 branch of the proved part 32 is also provided with an elongated slot 3l into which the bent end 33 of the arm 36 of the intermediate lever can project.
  • the slots 35 and 31 also permit the bent end 2'I to the arm I2 of the selection lever 8 to be inserted via both pronled parts 3l, 32 and the vertical part 33 in order to control the ball I I.
  • the lower end of the slot 3'! is so shaped as to prevent the withdrawal of the ball I I in the right-hand direction (Fig. 2).
  • intermediate levers 2 and 2 have been designed and interleaved in such a manner that the combined arrangement occupies a minimum amount of space necessary for an adequate operation oi the mechanism.
  • the present arrangement evidently aords means for the simultaneous operation of the vertical bars such as l and I. Further, although only one set of vertical bars such as I and I has been shown, it will be understood that several sets of vertical bars could have been selected simultaneously or in any order, one of the two control bars, or both at once, simultaneously actuating one or the other of the two vertical bars of the selected sets or both.
  • additional arms such as I2 could be provided on the selection levers such as 8 in order to place more than two vertical bars in the clutch position by the operation of a single selection lever, provided additional intermediate levers such as 2 are also used.
