  • Patent number: 4649718
    Abstract: In an ice maker having a mold defining at least one upwardly opening ice body forming cavity and a peripheral wall defining a top, structure for providing at least approximately 3 mm. clearance between components mounted to the mold and the mold wall top for preventing water which may be deposited on the mold wall top from being drawing by capillarity downwardly between the wall and mounted component. The structure further defines a drain for draining any liquid which may be deposited in the clearance space. The invention comprehends the provision of such a clearance spacing illustratively between the housing of a control mounted to the ice maker mold, the ice stripper mounted to the ice maker mold, and the water supply trough mounted to the ice maker mold.

  • Patent number: 4649712
    Abstract: A retention system for supporting a device on a first stationary member to have biased abutment with a cooperating second stationary member removably secured to the first stationary member. The system includes at least one resilient clip carried by the first stationary member and having a portion resiliently frictionally engaging the device so as to effectively retain the device in association with the first stationary member prior to the mounting of the second stationary member thereto. The spring clip further includes an end portion biasing the device outwardly from the first stationary member to be engaged by the second stationary member when the second stationary member is mounted to the first stationary member. The clip is removably retained in a slotted portion of the first stationary member for facilitated installation.

  • Patent number: 4160247
    Abstract: A housing enclosing a control for use in an electrical apparatus having structure defining a control space arranged to preclude access to the control in the housing when the housing is in the control space. The apparatus may include a connecting device for connecting the apparatus to an alternating current power supply for normal electrical operation of the apparatus. The control may comprise an alarm device which causes operation of the alarm upon a malfunctioning of the apparatus, and includes a battery for operating the alarm in the event of a failure of the power supply. The battery is removably connected to a circuit board portion of the control and a structural portion of the electrical apparatus prevents replacement of the battery and exposure of the control circuit when the housed control is in the control space and connected to the alternating current power source.
