A motorized operator is used for control of a closure, e.g., a garage door operator. Where the garage door is an upward opening door, there are four conditions for operation of the control system, namely stop-down, run-up, stop-up, and run-down. The present operator is one wherein safety conditions prevail, in that the run-down condition may not be established by a simple single closing of a switch because this might be effected carelessly or accidentally. The run-down condition is only established by plural closings of a switch. Gate means are provided within the control system so that the plural actuations of the switch will establish the run-down condition and this may be established only when the door is in the stop-up condition. The plural actuations of the switch must take place within a predetermined time period in order to establish the run-down condition.

Closure operator control

A multiple pole switch assembly is disclosed which is a simple structure of a housing having contact means and a metallic conductor comb with a plurality of teeth overlying the contact means. The housing is formed of base means and a cover therefor, which cover slides onto the base means in a first direction substantially parallel to the conductor teeth on the comb. The teeth of the comb extend through apertures in the base means and are clamped in position by the cover, with the cover latched in place on the base. The teeth extending through the base means may then be soldered to the base means, and the back of the comb may be broken off along a weakened area of the comb teeth. Switch actuator means is provided in the form of a thin insulator card having a preselected spacing of apertures in a row. The presence or absence of an aperture in the row establishes switch-open or switch-closed conditions. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

Multi-pole switch

An encoding transmitter is disclosed which includes a modulator providing a means to modulate a carrier wave selectively with a first or a second modulation frequency or pattern to provide first and second modulation patterns respectively. Also a third modulation pattern may be established by providing successive portions of the first modulation frequency and the second modulation frequency during a given time period. A data selector is controlled by data select control signals which are obtained from a counter counting from the first modulation frequency signal. Programmable means include a multi-position switch to program the input channels of the data selector so as to control whether the first or the third modulation pattern is that which modulates the carrier wave during any given unit of time.

Transmitter modulated with three modulation patterns

A door operator is disclosed which has a motor connected to open and close a door; for example, a garage door and a lamp is provided to illuminate the interior of the garage. Motor and lamp energization circuits are provided as controlled by switches; for example, a push button switch or a radio controlled switch. An alarm circuit is provided which may be a security alarm; for example, a burglar alarm or fire alarm. The alarm circuit is enabled when the door operator is not being used and the alarm circuit is disabled automatically whenever the door operator is being used. A time delay means is provided to maintain the lamp energized for a time delay period after the door has closed, and while the lamp is energized the alarm circuit is disabled, but as soon as the lamp is extinguished then the alarm circuit is enabled or armed.

Door operator with automatic control of auxiliary circuit

A switch mechanism is disclosed which is readily adaptable to a multiple pole switch mechanism wherein a removable card is supported in a housing. First and second contacts make up a switch pair and are mounted in the housing for mutual cooperation with the first contact having a mounting portion, a movable contact portion and a movable actuable portion. The removable card provides a selective actuation means to actuate the first and second contacts between open and closed circuit conditions. The card has abutment means to engage the movable actuable portion of the contact blade or blades. Also, the card has alternative areas which do not actuate respective ones of the contacts and this may be provided by apertures in the card so that no material of the card is present to engage the contact blade actuable portion. Accordingly, either open or closed circuit conditions may be achieved. Where the switch mechanism is a multiple pole switch, the card may have apertures and abutments as desired to achieve a desired combination of open and closed circuit conditions. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or application, and is not to be construed as a limitation on the scope of the claimed subject matter.

Switch mechanism

A two-pole off-set construction of an electric motor has winding portion laminations and rotor portion laminations which are separate so that the winding may be formed or placed on the winding portion and then the two portions of the stator interconnected to complete the flux path for the rotor circumscribed by a rotor aperture in the rotor portion. There must be a window space between these two portions to accommodate the winding on the winding portion and formerly the metal removed from this window space was scrap metal, necessitating an excessive amount of steel lamination material. In this invention, the layer of lamination is made in two complementary pieces and this layer has a rotor portion and a winding portion. The two separate lamination pieces for a layer of complete lamination are to permit the winding to be placed on this complete stator. The material removed from the window space instead of being scrap is utilized as an active flux carrying member by being unitary with one of these first and second lamination pieces.

Electric motor, stator and lamination therefor

An electrical switching device is disclosed comprising a first and a second support member engageable with one another forming a housing. A plurality of first and second contacts are mounted to the support housing and urged to be in contact with one another. A switching member such as an insulator having a plurality of contact apertures and a plurality of indexing apertures is movably mounted to the support housing and interposed between the first and second contacts. The insulator switching member separates some of the first and second contacts and allows electrical engagement of the others of the contacts through the contact apertures. The invention includes indexing means comprising a solenoid and an indexing member having an indexing arm to engage with an indexing aperture to move the switching member and the contact apertures to cause engagement or disengagement between the plurality of first and second contacts.
