  • Patent number: 4082825
    Abstract: A disclosed refrigeration cabinet has an integrated construction of sheet material and insulating foam which substantially eliminates the need for mechanical fasteners and welding, minimizes assembly operations, and permits the use of prefinished sheet panels. An outer cabinet shell preferably includes a prefinished sheet wrapped into a rectangular tube. The shell tube is reinforced at one end by a perimeter frame and at the other end by a thermal breaker collar. After the shell tube and frame are assembled, a liner is positioned in the tube and the breaker collar is installed. Rigid insulating foam is then foamed in place between the shell and liner to produce a sandwich construction in which the form secures and reinforces both the shell and the liner.

  • Patent number: 4074545
    Abstract: A safety interlock for a door of an automatic washing machine is disclosed. The interlock securely latches the door during a spin cycle to prevent the operator of the machine from opening the door and catching his hand in the rotating motor driven drum. The interlock operates during operation of the motor and during a time delay period following de-energization of the motor to permit the drum to coast to a safe speed or to a stop. Included in the interlock is a switch member operable upon closure of the door to at least partially complete a circuit between the motor and a bimetallic element. The remainder of the circuit is completed by a timer driven switch, and when the circuit is completed the bimetallic element is heated to move a latch on the frame of the appliance into locking engagement with a latch on the door.

  • Patent number: 4018096
    Abstract: A belt drive system in a washing machine for bidirectional operation in selection of agitation and spin cycles and having a belt and pulley arrangement adapted to transmit full motor torque in the agitation direction and substantially limited torque through belt slippage in the spin direction whereby final spin speed is reduced in proportion to out-of-balance conditions existing in the spin tub. A motor drive pulley having heat barrier means is provided to isolate friction heat generated by belt slippage on the pulley rim from the motor shaft and to prevent damage to elements in engagement with the shaft. A method of calibrating a belt tensioning spring is also disclosed.

  • Patent number: 3966283
    Abstract: A refrigeration cabinet construction wherein refrigeration tubing is permanently secured to cabinet walls by a tube securing and insulating foam which is compatible with the use of prefinished cabinet panels and which avoids the use of mechanical tube fasteners or other means which would otherwise disturb the appearance of the prefinished panels.
