  • the lower perimeter of the skirt portion 13 may rest on a floorboard (not shown) or the like, when the control 10 is in operative position.
  • a single control lever I6 extends upwardly from the frame 11. Specifically, the control lever 16 is secured to, and extends outwardly of, a mounting ball 18 universally pivoted in a socket 19 formed between the mating halves 12A and 12B of the housing assembly l2.
  • the axis 22 of the first throw arm 20 (FIG. 2) preferably comprises a linear extension of the axis of the control lever 16, and the axis 23 of the second throw arm 21 (FIG. 3 and 4) preferably lies at right angles to the axis 22 of the first throw arm 20.
  • This transverse orientation of the throw arms with respect to each other permits an absolute independence to the movement of the throw arms, as is generally preferable in the environment with which the operation of the subject control 10 will hereinafter be explained.
  • a series of guide slots pierce the socket 19 to delineate the ranges, and the directions, through which the control lever 16 and the two throw arms 20 and 21 can be displaced.
  • the control lever 16 extends through a guide slot 24 in the upper half '1 2A of the housing assembly 12, and the first throw arm 20 extends through a guide slot 25 in the lower half 12B of the housing assembly.
  • the throw arm 21 extends through a slot 26 provided at the juncture of the housing halves 12A and 128.

  • the centering arm 28 extends through a guide slot 29 also provided at the juncture of the housing halves 12A and 128.
  • the guide slots 26 and 29, though opposed, lie in a plane oriented transversely to the axis 22 of the first throw arm when the first throw arm is in its neutral position (FIG. 2) in order to permit the second throw arm 21, and the centering arm 28, to rotate about axis 22 in response to rotation of the control lever 16 about its own axis 22.
  • a'T-shaped handle 30 may be nonrotatably secured thereto.
  • the first motion transmitting means such as push-pull cable 35, is operatively attached to the first throw arm 20.
  • the pushpull cable 35 may be of any conventional construction having a core 36 that slidably reciprocates within a casing 38 to transmit mechanical motion by the application of either tensile or compressive forces to the core 36.
  • the casing 38 is formed of a plurality of casing wires 39 laid contiguously, in the. form of a long pitched helical coil, about the radially outer surface of an inner, flexible plastic tube 40 which extends the full length of the casing 38.
  • An outer cover 41 encases the coil of wires 39 up to within a short distance from the ends thereof.
  • a fitting 42 is positioned over the end of the cable casing 38 and is cold swaged, or otherwise suitably connected, onto and exposed end portion (not shown) of the cylindrical grouping of wires 39.
  • a plurality of annular ribs may be provided within the fitting 42 which, when crimped onto the cover 41, effect a seal between the end fitting 42 and the cover 41.
  • a retaining groove 43 is provided on the exterior of the fitting 42 for engagement with the skirt portion 13 of the frame 1 1.
  • the skirt portion 13 may be folded from a single sheet of metal, the opposed edges 44 and45 of which, as best seen in FIG. 7, are thereby brought into juxtaposition.
  • Opposed, semiannular notches 46 and 48 are recessed into the respective edges 44 and 45 and are received within and embrace the retaining groove 43.
  • Spaced ears 49 and 50 on one end of the multipurpose bridge 51 that stands between the front and back walls 52 and 53, respectively, of the skirt portion 13 are also received within the retaining groove 43 and bent to embrace the fitting 42.
  • the thickness of the opposed edges 44 and 45i.e., the front wall 52--combined with the thickness of the individual ears 49 and 50 substantially equals the axial dimension of the retaining groove 43. In this way the interaction of the notches 46 and 48, the ears 49 and 50 and the retaining groove 43 fully secures the cable casing 38 to the control 10.
  • the core 36 which is preferably of the solid wire variety, extendsoutwardly through the end fitting 42 to the throw arm 20.
  • a terminal fitting 54 as best seen in FIG. 6, is secured, as by staking, onto tle core 36.
  • the stem portion 55 of the fitting 54 projects outwardly in substantial alignment with core 36 and presents a ball 56 that is received within a cavity 57 in the throw arm 20.
  • a generally C-shaped spring clip 58 embraces the throw arm 20, and the opposed ends of the clip 58 are notched, as at 59, to conform concentrically with stem 55 and thereby retain the ball 56 within the cavity 57 and yet permit it to swivel freely therein 'to accommodate the rotative motion of the throw arm 20-about either its own axis 22 or axis 23- with the least possible flexure being imposed upon core 36.
  • the core 61 which is also preferably of the solid wire variety, extends outwardly through the end fitting'63 to the second throw arm 21.
  • a terminal fitting 71 secured to the core 61 also presents a ball 72 received within a cavity (not shown, but which may be similar to cavity 57 in arm 20) in the throw arm 21 and retained therein by a spring clip 73.that permits the ball 72 to swivel freely and thereby reduce the flexure imposed upon core 61.
  • detent means 75 may comprise a pair of detent springs 78 and 79 captured within cylindrical cavities 80 and 81 recessed into the housing assembly 12.
  • the two cavities are generally opposed, and the two halves 12A and 123 in the housing 12 are relieved, as at 82A and 828, to accommodate the swinging movement of the centering arm 28 into and between the generally opposed. cavities 80 and 81.
  • actuation of the remote mechanism controlled by the second motion transmitting means requires approximately a 38 swing of the second throw arm 21 about axis 22i.e., approximately 19 on each side of the neutral position.
  • the relieved portions 82A and 828 in the housing assembly 12 must be of a dimension sufficient to accommodate a concomitant swing of the centering arm 28-the extreme ranges being represented by the chain line positions 28a and 28b in FIG. 3.
  • each detent spring engages the centering arm only on one side of the neutral position represented in FIG. 3. Accordingly, each spring is inclined such that its axis will lie normal to the centering arm 28 at only one point during its wing, and it has been found that if that point is located at approximately two-thirds of the angular range between neutral and full swing, the spring operates far more effectively.
  • the axes 83 and 84 of springs 78 and 79 are, respectively, perpendicular to reference lines 85 and 86 located approximately 12 on either side of the neutral position.
  • the detent means 76 comprises a coil spring 88 captured within the multipurpose bridge 51 by a tab portion 89 that extends axially interiorly thereof.
  • the axial extend to which the tab portion 89 can penetrate the spring 88 is limited by the axial dimension of the spring itself and the range through which the spring must compress to allow the rotation of the throw arm 20 necessary to displace the core 36 of cable 35 the required amount.
  • the throw arm 20 swings through an arc while the axis of the detent spring 88 remains fixed and the considerations with respect to the determination of the inclination for the springs 78 and 79 in detent means 75 can be applied equally to determine the inclination of spring 88.
  • the axis 90 of spring 88 lie perpendicular to a reference line 91 displaced at approximately 12 from the neutral position of throwarm 20.
  • a retaining means 95 by which the throw arm 20 may be held in at least one of its fully displaced positions.
  • a retaining means 95 may comprise a base, portion 96 (FIG. 4) secured, as by rivet 97, to a mounting flange 98 that extends outwardly of the bridge 51.
  • the pair of resilient arms 99 and 100 that extend outwardly from the spaced ends of the base portion 96 are corrugated to embrace the throw arm 20 and terminate in tingers 101 and 102 that diverge with respect to each other in order to permit a guided entry of the arm 20 into the retaining means 95.
  • the resilient arms 99 and 100 should be of sufficient strength to retain the throw arm and yet permit it to be engaged upon the application of a modest force to the control lever 16.
  • the wire 104 of an insulated electrical 105 is secured, as by a soldered joint 106, to a spiderlike switching means 108 having three, resilient, conductive blades 109, 110 and 111.
  • the conduit 105 may enter through a passageway 112 between the halves 12A and 12B of the housing assembly 12 and be locked in position by the interengagement of the annular ribs 113 along the interior of the passageway with the outer cover, or insulation, 114 on the wire 104 when the two halves 12A and 12B of the housing assembly are secured together.
  • Blades 109 and 110 extend outwardly in opposite directions and presents contacts 115 and 116 that lie within the plane through which the throw arm 21 and the centering arm 28, respectively, swing as a result of rotating the control lever 16 about its own axis 22.
  • a contact button 119 should be secured on each to assure completion of the circuit required between the switch means 108 and the arms 20, 21, or 28.
  • a utility device 125 is provided with a blade 126.
  • a typical mount attaches the blade to the vehicle through a compound frame 128.
  • a first frame member 129 is generally triangular with a pair of laterally spaced,
  • a second frame member 132 is pivotally mounted to the apex of the first frame member 129, as at 133, for horizontal swinging movement.
  • Blade 126 is carried directly on the second frame member 132.
  • a first cylinder 134 is secured between the vehicle 125 and the first frame member 129 to raise and lower the compound frame 128, and blade 126, about the pivotal connections and 131.
  • the second and third cylinders 135 and 136 are attached between opposite sides of the first frame member 129 and the second frame member 132 to swing the second frame member 132, and blade 126, horizontally about the pivot 133.
  • a pump and valve unit 138 contains a fluid reservoir, a fluid pump and a valving arrangement whereby fluid may be selectively pumped, under pressure, to the three cylinders 134, 135 and 136 through conduits 139,140 and 141, respectively.
  • the aforedescribed axial movement of the core 36 positions a valve, not shown, within unit 138 and at the opposite end of cable 35 so that fluid is pumped through conduit 139 to cylinder 134.
  • the admission of pressurized fluid into cylinder 134 raises the frame 128 about the pivotal connections 130 and 131 to raise the blade.
  • the blade 126 is raised to the desired height, and the control lever 16 is permitted to return from the chain line position 16a to the solid line position 16, as under the biasing action of detent 76.
  • This movement retracts the throw arm 20 from the blade 111 to break the circuit from wire-104 to ground and thereby stop the pump in unit 138.
  • the same movement of throw arm 20 also returns the core 36 to the neutral position. in the neutral position the valve in unit 138 causes the pressurized fluid to be retained within cylinder 134, thus maintaining the blade 126 in the elevated position selected.
  • the aforedescribed axial translation of the core 61 operates a valve (not shown) in unit 138 that opens the conduit 141 to admit pressurized fluid into cylinder 136 and at the same time opens conduit 140 to permit a corresponding amount of fluid to emit from the cylinder 135 so that the blade will swing to the chain line position 126a.
  • the operator need only release handle 30.
  • the spring 78 of detent 75 then acts to return the centering arm 28 and the throw arm 21 from positions 28a and 21a, respectively, to their neutral position.

  • the blade 126 is hereby maintained in position 126a.
  • throw arm 21 also translates the core 61 of push-pull cable 60 axially inwardly with respect to casing 62. 'his translation of core 61 operates a valve (not shown) in unit 138 that opens conduit 140 to admit pressurized fluid into cylinder 135 and at the same time opens conduit 141 to permit a corresponding amount of fluid to emit from cylinder 136.
  • the spring 79 of detent 75 then acts to return the'centering arm 28 and the throw arm 21 from positions 28b and 21b, respectively, to their neutral position.
