US Patent:

49451960, Jul 31, 1990

Filed:

Jul 28, 1989

Appl. No.:

7/386163

Inventors:

Joseph J. Mahon - Libertyville IL
Robert K. Aigner - Chicago IL

Assignee:

Eaton Corporation

International Classification:

H01H 708

US Classification:

200 38C

Abstract:

A programmer/timer for an appliance of the type having a rotatable cam drum advanced for sequential actuation and deactuation of a plurality of electrical switches. The drum is advanced or indexed intermittently by an oscillating advance pawl engaging a ratchet wheel and also continuously by a gear driven by a common motor for oscillating the advance pawl. The ratchet wheel has a hub which is frictionally engaged to drive the cam drum. The driven gear in turn is frictionally engaged with the hub to also drive the ratchet wheel. When the advance pawl engages the ratchet wheel for intermittent drive, the driven gear slips on the ratchet hub. Upon user selection, a separate cam track lifts the advance pawl to permit the driven gear to continuously drive the ratchet wheel.

Appl. No.:

6/495895

Inventors:

Joseph J. Mahon - Libertyville IL

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

G08B 100

US Classification:

34030915

Abstract:

A single timing motor (26) drives a gear box (54) having an output shaft (56) for indexing a ratchet wheel (62) for turning a cam drum (68). One cam track (72) operates a line switch (22) for controlling the program interval "ON" time of the appliance. A second cam track (70) operates a second line switch (40) for controlling the timing motor. A toothless space (66) in the ratchet wheel stalls cam drum advance upon program interval time-out to maintain the timer switch (40) closed to keep the motor running. Output shaft 56 drives a sub-interval cam (80) which cycles a switch (48) for effecting intermittent appliance "ON" time for a minor portion of the sub-interval period to provide a "KEEP-WARM" mode of operation. An alarm bell (100) is sounded by a striker (98) actuated by the sub-interval cam. The operator manually advances the cam drum (68) for de-actuating the timer motor switch (40).

Inventors:

Joseph J. Mahon - Libertyville IL

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

H01H 4300

US Classification:

307141

Abstract:

A programmer timer for an appliance, such as microwave cooking oven, having a magnetron power switch positioned by a control selectively moved to one of three power level settings by user rotation of the single rotary knob to a selected position on one of three separate cooking program interval range scales on the dial. Selection of a knob position on the first scale provides a 100% magnetron duty cycle, or full "ON", cooking mode for the desired cooking interval, selection of a knob position on the second scale provides a first predetermined fractional duty cycle for "MEDIUM" power level magnetron operation for the desired cooking interval; and, selection of a knob position on the third scale provides a second predetermined fractional duty cycle for "LOW" or "DEFROST" power level magnetron operation for the desired cooking program interval. A single timing motor drives a cam advance mechanism for effecting time-out of the selected program interval for the three power levels of operation.

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

G04F 800
H01H 4300

US Classification:

368113

Abstract:

A programmer/timer for an appliance of the type having a rotatable program cam advanced by an oscillating pawl engaging a ratchet wheel for actuating at least one appliance function switch. A shaft is provided for enabling user positioning of the cam after limited rotational lost-motion for selecting the program interval. An annular member having a conical cam surface is received over the shaft and is helically cammed to the shaft. During the limited lost-motion rotation of the shaft, the collar moves axially and the conical cam surface lifts the pawl from the ratchet thereafter enabling user rotation of the program cam for positioning same for program interval selection.

Appl. No.:

6/696766

Inventors:

Joseph J. Mahon - Libertyville IL

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

H01H 4300

US Classification:

200 38A

Abstract:

A push button member (10) is mounted to be moved longitudinally between a first position (FIG. 1A) and a second position (FIG. 1B). The push button member includes a cam surface (16) for selectively camming an electrical contact engaging surface (18) and a hold surface (48) past a follower member (32) as the push button member is moved from the first position to the second position. In the second position, the electrical contact engaging surface urges electrical leaf spring contacts (20) into a closed conducting relationship. The spring contacts remain in the conducting relationship until a radially greater extending cam surface (52) of a timing cam (50) engages the follower member moving it to the release position. In the release position, a spring (12) biases the push button member from the second position back to the first position allowing the electrical contacts to open.

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

H01H 4300

US Classification:

200 35R

Abstract:

A timing control system and timer sub-assembly for microwave cooking source parallel connected with a timer and series connected with an interval time switch and a defrost cycle switch and a power level selector. The timer is operable to cycle the defrost switch at a fast rate for selected operating timer intervals of a given value or greater and a slow rate for selected interval less than the given value. The timer provides progressively decreasing "on" time of the defrost cycle switch for each cycle. The timer sub-assembly has a pawl-driven ratchet wheel having a toothed sector of lesser pitch diameter and a masking ratchet wheel having periodic deep notches spaced thereabout for permitting the drive pawl to periodically engage the teeth lesser pitch diameter for slower advance of the driven ratchet wheel for indexing a plurality of rotary cam tracks for microwave sources switch actuation.

Assignee:

International Classification:

H01H 708
H01H 4310

US Classification:

200 39R

Abstract:

The follower tip of the switch operating bell-crank lever can ride on the large diameter of the axially movable, rotatably driven cam or on axial movement of the cam can drop onto the smaller diameter of the cam to close one switch and, upon further axial movement, the follower can move further in to a pseudo inner diameter to close a second switch. The lever acts to prevent return axial movement of the cam until the cam notch is aligned with the follower and the follower no longer interferes with axial movement.
