Definitions

  • the disc has various radially and circumferentially positioned holes into one of which a selected pin may drop to thereby correctly position the timer at the start of the selected cycle.
  • Three holes are provided in the disc on the radius of the soak" pin and a masking arrangement covers or uncovers, as the case may be, the soak" holes so only that hole which properly combines with the selected cycle is operative.
  • the masking arrangement is actuated by one of the possible cycle pins. Therefore, a soak period may be selected to precede any of a number of cycles while employing only one soak button and one soak" pin.
  • This invention provides a masking arrangement coupled with multiple soak positions and actuated by wash cycle selections to limit the effective soak position to the one properly preceding the selected cycle.
  • FIG. 1 is a plan view of an assembly ofa timer, selection buttons and the selection mechanism. Only the selection buttons and timer knob are visible to the user.
  • FIG. 2 is a split, enlarged view of the extreme left and right portions of FIG. 1.
  • FIG. 3 is a fragmentary side elevation from line 3-3 in FIG. 2.
  • FIG. 4 is a view of the pin and disc arrangement from line 44 in FIG. 2.
  • FIG. 5 is an exploded perspective of the disc and mask assembly.
  • FIG. 6 is a view showing the manner in which the mask is actuated. This is a meandering section on line 66 of FIG. 10.
  • FIGS. 7-10 are similar views showing the relative positions of the mask, disc and selected pins for various possible soak positions.
  • buttons at the left in FIG. 1 are used to select the desired function or cycle of the machine.
  • the four right-hand buttons do not select a rotary position of the timer but electrically modify a selection in the case ofthree buttons and the cancel button cancels all previous selections.
  • the pre-wash and soak buttons can be selected in combination with certain other buttons.
  • the remaining buttons are mutually exclusive in that depressing and latching one will cancel a prior selection from among that group.
  • Each of the ten buttons on the left will actuate or set a pin which functions to select the rotary position of the timer at the right of FIG. I.
  • the details ofthc timer are not shown in the drawings.
  • the timer may be any desired type.
  • the pins are denoted by letter designations on the drawings to simplify orientation to the holes in the disc, the holes being designated by similar letters which correspond to the selection buttons.
  • the soak button selects pin S which will find" hole S.
  • Each pin has an enlarged central portion between the plates 20,22 which is engaged by the associated wire end. The ends of the pin guide the pin and the lower end engages the disc.
  • a bearing plate 30 is fixed to the underside of disc 24 by screws 32,32 with the radial keys 34 engaging slots 36 in the disc and the central bushing 38 serving to mount the disc and plate on the timer shaft.
  • the plate mounts on the disc with rim 40 against the underside of the disc so annular lip 42 is spaced from the disc with the hub 44 of stamped and formed member 46 captured between the disc and lip 42 for rotational movement relative to the disc.
  • the member has a depending finger 48 engaged by the end 50 of spring 52 coiled around the bushing 38 and engaging pin 54 fixed in the bottom of the hub. This biases the member clockwise to the limit position determined by engagement of the vertical front faces of actuators projecting up through slots in the disc.
  • the member 46 has arms supporting actuators. Actuator 56 projects up through slot 58 and another actuator 60 projects through slot 62. These two acutators 56,60 lie on the radius of Knitted Fabric pin KF and will be engaged by pin KF if it has been set. When so engaged, member 46 is restrained from moving with the disc and various masks (80,82,84) are moved relative to certain holes (S, PP+S, KF+S) in the disc. As movement continues, the sloping face of the actuator will be engaged by the end of the slot to cam the actuator down and disengage the mask for return to its normal position, its function having been served.
  • FIG. 7 the pin 5 is designated as actuated by being shaded and is shown in the hole 8.
  • the pins KF, PPW, and PPC are on the same radius as actuators 60, 68 and 74, respectively. Had any of these pins been set, it would have engaged its associated actuator to move mask 80 across hole S to prevent entry at that position to bypass that potential position. Subsequently the engaged actuator would be cammed down to release the pin. ln FIG. 8 both CLW and S have been set. The soak" position is the same. Thus soak only (FIG. 7) or soak plus Cotton, Linens, White (FIG. 8) result in pin 5 finding the same starting point.
  • pin S, PP+S find" the proper hole from the three potential holes, 8. PP+S and KF+S.
  • the associated actuator (68, 74,60) will move mask 80 to block hole 5 and bypass the position.
  • lf on the other hand, only S or S+CLW have been set, pin S will drop in the hole to position the timer. If S has not been set, normal positioning is effective.
  • Pin S should drop into hole PP+S only if one of the two Permanent Press cycles has been selected. Therefore, mask 82 should be moved to expose PP+S only by pin PPW or PPC engaging actuator 68 or 74. No other pins will move mask 82 to its inoperative position.
  • hole KF+S can be exposed only by pin KF engaging actuator 56 to move mask 84 to its inoperative position.
  • a plurality of selectable means mounted adjacent the member for movement between active and inactive positions.
  • each of said selectable means having an associated stop means whereby a selectable means in active position will engage its associated stop means at a predetermined desired and selected position in the path of movement of the member,
  • one of the selectable means having a plurality of associated stop means whereby a plurality of selected positions exist in conjunction with said one select able means
  • Apparatus for selecting a desired position of a device including a rotary disc,
  • each of the pins being at different radial distance from the axis of rotation of the disc whereby there is a separate rotational path on the disc for each pin,
  • one rotational path being provided with plural stops means whereby the specific pin associated therewith potentially has plural positions in which it engages a stop means
  • actuating means engageable by certain pins to actuate said masking means between said active and in active positions.
  • said plural stop means comprising multiple holes at equal radial distance from said axis and circumfer entially spaced
  • said masking means being operative to prevent entry of a pin when in active position.
  • Apparatus according to claim 4 in which the masking means associated with one of said multiple holes is normally in inactive position and is moved to active position by engagement of any of certain selected pins with the actuating means.
  • Apparatus according to claim 5 in which the masking means associated with another of said multiple holes is normally in active position and is moved to inactive position by engagement of a certain selected pin with the actuating means.
  • said means responsive to actuation of both selecting means being engageable by the pin associated with the actuated program selection means and operative to render only one of said plurality of positions effective 9.
  • the disc has stop means at each of said plurality of positions and said responsive means comprises a masking device movable between an active position masking a stop means and an inactive position in which the stop means may be engaged by the pin associated with the selected program.
