The drive train of an appliance timer includes a slip clutch formed of a triangular spring meshing with the outer flat surfaces of a hexagonal drive shaft. The slip clutch is incorporated into a drive pinion in the appliance timer drive train. Excessive torque causes the walls of the triangular spring to resiliently bend outward under rotational pressure from the drive shaft, permitting the drive shaft to rotate without rotating the drive pinion. When used in an icemaker, the slip provided by the clutch alleviates the need for an expensive, stallable motor.

Time switch with clutch mechanism and cam operated contacts

An improved icemaker having a number of features, including: a dual-activated feeler bar switch which combines the motion of two cams to operate a single switch; an adjustable-duration water fill switch which is closed by rotating a connector between two contacts; switches mounted to make wiping contact so as to clean the contact area; a combination deflector which not only deflects ice removed by the ejector from the ice mold, but also supports and lifts a feeler bar to determine whether the ice storage bin is full; a clutch mounted between the motor and ejector bar to permit slip therebetween so as to avoid stalling the motor as the ejector bar presses upon ice in the mold; a manual start button for starting the motor, simplifying installation; and an anti-back mechanism in the icemaker drive train to prevent an installer from damaging the icemaker by rotating it backwards.

An oven latch mechanism for heat-cleaning ovens is disclosed. The latch mechanism employs a unidirectional rotating d.c. motor to automatically latch the oven door upon initiation of a heat-cleaning operation and to automatically unlatch the door after a heat-clean operation and after the oven has reached a predetermined lower temperature. The latch mechanism includes a latch arm which moves arcuately through a variety of positions. The latch member senses whether the door is open and follows a different path of motion accordingly. If the latch member senses an open door, it returns to an unlatched position.

Motorized range lock

A switch arm connector block for mounting a plurality of spring switchblades in a predetermined array for sequential cooperation with a timer cam and for providing a quick-disconnect connector for electrically connecting the blades to a wiring harness is disclosed. The connector block is formed by a plurality of insulating wafers which encapsulate a plurality of flat, parallel switchblades. The faces of the wafers are spaced from each other by projecting curbs around the perimeters of the wafers and window openings are provided in the wafers so that internal bussing may be provided in the block. End bussing is provided and the end bussing strips are covered by a protective cap having insulating fences for protecting the bussing strips.

A system of rigid, generally planar dimensions adapted to by removably, hingeably coupled to a conventional ventilator louver assembly to environmentally seal same to prevent energy losses. The louver covering system includes a rigid, generally rectangular frame formed of specially extruded members, which frame surroundably supports a rigid, generally planar insulating sheet. The frame includes front, side, and rear extrusion members which include integral bosses to aid in assembly. A separate, rigid, elongated extruded hanging rail having a hinge portion is adapted to be permanently coupled to the louver assembly. The system frame rear includes a cooperating hinge portion, which, when coupled to the aforementioned hanging rail hinge coupling extrusion enables the system to be hingeably swung to a closed position relative to the louver assembly. Latching means, preferably coupled to the louver assembly, may be manually twisted to engage flange portions of the frame to seal the louver. Frame channels support a plurality of insulating strips which form a surrounding seal which minimize air currents otherwise associated with conventional louver assemblies.

Removable louver covering system

A safety switch for a vacuum cleaner which includes a vacuum cleaner housing, at least two attachments adapted to be affixed to the housing, and a switch casing fixed to the housing. First and second slides are mounted for reciprocation in the casing relative to the casing and relative to each other. A pair of socket openings are provided in the casing. Each of the slides are provided with a cam surface which is located in each socket opening. Each cam surface slopes inwardly toward a central axis of each socket. Each attachment has a probe adapted to enter one or the other of the sockets when the attachment is mounted on the cleaner. Each of the probes being adapted to move the first and second slides in opposite directions a predetermined total relative distance. The first slide is adapted to operate a first plurality of switch arms while the second slide is adapted to operate a second plurality of switch arms. The switch arms of one of the pluralities alternating with the switch arms of the other one of the pluralities so that contact will be made between at least two switch of each plurality when a probe is inserted in one of said sockets and so that contact will be made between at least four switch arms of each plurality when a probe is inserted in the other socket.
