  • Cam arms 30 and 34 are locked to cams 26 and rotation of arms 30 and 34 will operate to drive cam members 26 in an identical rotary movement.
  • Arms 30 and 34 are shown in FIGURE l in the fully opened position; the fully closed position being parallel to frame side pieces 16 and 18 with the upper face of each arm resting against the olfset on each side piece indicated by numeral 17 with respect to side piece 16.
  • Handles 32 and ⁇ 36 are useful in rotating arms 30 and 34 downwardly from the closed position.
  • a front bay 38 having a rigid frame 40 mounting four insulating panel members 42 apertured as at 43 to receive pin assemblies interconnected in pairs by patchcords such as 45.
  • Frame 40 may be comprised of stainless steel or aluminum stock suitably milled to accommodate panels 42; or as in the preferred construction shown in FIGURE 1 may be comprised of an interior frame of ock filled phenolic resin member 46 surrounded by stainless steel bar members 47.
  • At opposite corners secured to the vertical members of frame 40 are projecting pin members; the upper pin members (not shown) being similar to lower pin members 52 and 54.
  • handle members 48 employed to lift and manipulate front bay 38.
  • latch mechanisms 66 and 68 Located at the bottom interior of rear bay 12 are latch mechanisms 66 and 68 positioned in slots 62 and 64 of side pieces 16 and 18. As shown in FIGURE 1, the latch mechanisms are set back into side pieces 16 and 18 so as to provide free travel of frame 40 of 38 into the face of 12. Each mechanism 66 and 68 is positioned so as to be engaged by one of the pin members 52 and 54 as 38 is closed into 12.
  • Operation of assembly calls for an initial placement of front bay 38 as shown in FIGURE 1 with the upper pin members resting in pivotal relationship within slots in plate members 19 and 21 set into the side pieces 16 and 18 of 12. Following this initial placement, front bay 38 may be swung downwardly and into the face of rear bay 12 pivoted on the upper pin members. As 38 enters the face of 12, pin members 52 and 54 engage the lower forward surfaces of each latch mechanism 66 and 68, respectively, driving such upwardly to be returned under spring pressure in a manner to be described more fully hereinafter. With 38 fully seated within 12, latch mechanisms 66 and 68 serve to hold 38 within the face of 12 by holding pin members 52 and 54 against withdrawal.
  • front bay 38 is latched against outward movement regardless of the attitude of assembly 12 and even in the presence of jars, shocks or substantial gravitational forces applied to assembly 10 through the dis-A v placement of the vehicle, craft or other housing in which assembly 10 is situated. Furthermore, with front bay 38 latched by assemblies 66 and 68, a proper alignment of 38 is assured with respect to cams 26. With 38 in the closed position, arms 30 and 34- may be rotated upwardly Y to drive cams 26 into engagement with the lower surface 39 of frame 40 and thereby drive the pin members of the front bay into a particular wiping contact withthe spring members of the rear bay to perform a given programming function in the same manner as taught in the Weg patent.
  • front bay 38 is locked within 12 and cannot be withdrawn therefrom until arms 30 and 34 and cams 26 have been rotated to place further operate to lock front bay 38 within rear bay 12.
  • 38 When 38 is latched within 12 it may be withdrawn by pulling on handles 48 in a sharp outward movement.
  • assembly 38 is locked within 12, no amount of pulling or other force will operate to move 38 with respect to 12.
  • FIGURE 2 shows the assembly 66 exploded relative to slot 62 of side piece 16.
  • Latching mechanism 68 fitted within side piece 18 is identical in function and substantially the same in structure having certain portions reversed for obvious reasons.
  • each aperture is such as to receive in a close fit stepped pin members 74 each having a lower portion 76 and an enlarged upper portion 78 adapted to nest within complementary bores of the respective apertures as shown more clearly in FIGURE 3.
  • Each of the pin members 74 is internally threaded in portion 76 to receive externally threaded screw portions 73 of members 72 which operate to secure pin members 74 against relative movement with respect to side piece 16.
  • the enlarged diameter portion 78 of pin members 74 is of a length to define a space when the pin members are fully seated slightly greater than the thickness of a latch plate 80.
  • Each pin member 74 includes a head portion 79 adapted to hold plate 80 and is of a length when fully seated so as not to project within the face area of rear bay 12 and interfere with the movement of closure of front bay 38.
  • latch plate 80 Adapted to fit within slot 62 is latch plate 80 having longitudinal slots 94 by which 80 is held against all but sliding movement by the portions 78 of pin members 74.
  • Plate member 80 in the preferred embodiment is made of stainless steel suitably drilled and formed to include at one end beveled edge 82 and at the other end beveled edge 84 serving to eliminate manufacturing tolerance problems with respect to what otherwise might be sharp edges hindering sliding movements of plate 80 in slot 62.
  • a pointed portion 86 At the end adjoining edge 84 and integral with plate 80 is a pointed portion 86 defining a forward cam surface 88 and a rearward cam surface 90 abutting a cam surface 92 approximately transverse to the longitudinal axis of 80.
  • a bent out tab portion 98 having a spring stop portion 100 adapted to hold one end of a relatively stii compression spring 102 against one end of channel 65.
  • the assembly lforming the latching mechanism of the invention is assembled as shown in FIGURE 3 with the plate member 80 held against all but longitudinal movement within slot 62 by the cooperation of slots 94 with portions 78 of pins 74.
  • Spring 102 is Vheld within channel by plate 80 and engagement with 100 and by further engagement with channel 65. It is preferred that spring 102 have a length and characteristics such as to drive plate 80 under considerable force against pins 74 in the position shown in FIGURE 3; the position existing when rear bay 12 does not contain a front bay.
  • FIGURE 4 depicts 80 in the position the assembly in the open position. This feature precludes A accidental damage to either pin or contact spring members through premature attempts to withdraw the front bay from the rear bay.
  • Mechanisms 66 and 68 thus operate to both latch front I bay 38 within rear bay 12 before interconnection of circuit pathsis called for and, following interconnection,
  • FIGURE 3 the rest position.
  • latch pin members thereof including pin 52 will be driven in the arcuate path indicated by the arrow in FIGURES 1 and 4.
  • member 52 will strike the forward surface 88 of 86 as indicated in FIGURE 5, the slope of which will produce a resultant force driving plate in travel along 62 limited by the diameter of 52 and the line of travel thereof.
  • 52 moves further inwardly Ythe apex of 86 will be passed and 52 will contact face and face 92, plate 80 being driven downwardly by spring 102 to the position indicated in FIGURE 6.
  • front bay 38 is latched within rear bay 12 Y and removal or withdrawal of 3:8 may be accomplished by pulling outwardly on handles t8 with a force sufiicient to result in forces exceeding the spring force of springs 102 in both mechanisms 66 and 68. 1
  • FIGURE 7 depicts the movementl of latch mechanism 66 caused by the coincident displacement of pin member 52.
  • plate titl is stopped against further movement in slot 62 by pins 74 engaging the surfaces 95 of apertures 94.
  • FIGURE 7 the configuration of plate' surfaces 86 and 90 taken in conjunction withthe disposition of plate bfi positively'precludes withdrawal of front bay 38 by blocking forward movement of pin member 52. Front bay 38 is then locked within.
  • the mechanisms 66 and 6d operate to both latch and lock a plugboard front bay within a plugboard rearv bay.-
  • the movement of the plate member mechanisms 66 and 63 is limited to approximately the vertical movement of the front bay in the final movement of closure. This distance is also defined by the differences in cam radius and further defined by the spacing-between pin and contact spring members with the iront .bay positioned within the rear bay before closure.
