  • Patent number: 5443541
    Abstract: This invention relates to a clothes dryer which can successfully cope with operation when the air circulation path is partially blocked. The dryer is of a type having dual heating elements and during conditions where blocking exists, the heat generation is reduced by disconnecting one of the heating elements while air is circulated thru the dryer.

  • Patent number: 5416400
    Abstract: This invention relates to a circuit for energizing a device in a domestic clothes dryer from a source of potential which if directly connected across the device would lead to premature failure of the device. In order to drop the potential applied to the device, the start winding of the drive motor is serially connected in the circuit containing the device to drop the potential applied to the device.

  • Patent number: 4994654
    Abstract: A support bracket and a method for mounting a heating coil in a dryer or the like by means of such bracket is disclosed. The support bracket is a plate of unitary construction having one or more openings for receiving and supporting an insulating bushing and a pair of support legs adapted for engagement with slots in a support wall. At least one portion of the plate is folded upon itself to form a retaining rim for the bushing and reinforcing the support legs.

  • Patent number: 4687262
    Abstract: The cabinet of an appliance with a downwardly opening door is stabilized by a pair of legs each pivotally mounted to the cabinet on an axis fixed to the cabinet and oriental relative to the cabinet so that pivotal movement of each leg above its respective pivotal axis moves the foot of the leg forwardly and downwardly into a supporting position or movement of the door to closed position retracts the legs to their initial position.

  • Patent number: 4677760
    Abstract: A conventional clothes drier is provided with a rack structure mounted on the bulkhead that extends into and plugs the access opening to the drum of the drier. The rack is selectively mountable in either an operative extended position projecting cantilever fashion into the drier drum or alternatively in a retracted or storing position wherein the rack is contained within the bulkhead.

  • Patent number: 4656340
    Abstract: A heater coil mounting is provided by means of a bracket having seats formed at or adjacent each axial end and into which an insulator through which the heater element passes, is adapted to be received. The bracket is mounted in position on a wall using tabs which cooperate with portions of the bracket to hold the bracket close to the wall and form a further portion of the seat to lock the insulator in position.

  • Patent number: 4628661
    Abstract: An appliance frame having a score line formed by pressing metal to form a plurality of dimples each having a substantially straight severed edge extending out of the plain of the metal and arranged in a substantially straight line to form the score line, thereby to weaken the metal sufficiently that it may be manually bent to form a substantially right-angle bend at the score line.

  • Patent number: 4628617
    Abstract: A drum for a clothes drier formed from a cylindrical sleeve into which is inserted a pair of opposed head structures, each provided with a seat snugly received in the adjacent end of the sleeve and terminated by an abutment to limit the penetration of the head into the sleeve. Axially extending projections are provided at each end of the sleeve and these projections are bent around their adjacent seats thereby to hold the heads and sleeve together.

  • Patent number: 4593441
    Abstract: A one piece substantially W-shaped plastic clip has a pair of outer legs that are flexible and can move in a first direction toward an intermediate member that in turn is movable in a direction substantially perpendicular to the first direction of movement above described. Each leg has a notch on its side remote from the intermediate member and the intermediate member has a catch projecting from a side facing perpendicular to the first direction. The notches mount the clip to a first panel and the catch is adapted to cooperate with a second panel member to retain same in position.

  • Patent number: 4586269
    Abstract: A drier drum bearing structure formed from a single piece of molded plastic to provide a right cylindrical outer bearing wall. The bearing structure is mounted on a non-circular access opening through the drier cabinet wall on a peripheral flange extending around the opening on the wall which is received within a mounting cavity formed in part between the outer cylindrical bearing surface and an inner wall and is held in position by means of bosses on the bearing structure cooperating with mating bosses on the peripheral flange to permit movement circumferentially about the access opening while substantially preventing axial movement.

  • Patent number: 4555827
    Abstract: The present invention relates to a retractable undercarriage formed preferably by three supporting members, two of which are leg members and the third a wheel member. The support members are moved to either move the leg members into supporting position and retract the wheel member, or to move the leg members into the retracted position and the wheel member to the supporting position. When the leg members are in the retracted position and the wheel member in supporting position the end of the cabinet that would otherwise be supported by the foot members rest on further wheels so that the cabinet is completely supported on wheels and may be moved relatively freely about the floor.
