Abstract
A timer device has the ability to be programmed to skip specified time intervals where it is desired that the operative sequence initiated at predetermined times be avoided. The device has moveable timing elements which can be inserted at selected locations on a rotating timing dial to determine the start, termination and duration of an operative sequence. Additional moveable elements on an associated slip wheel can be inserted at selected locations to determine a time interval during which the operative sequence can be avoided.
Claims20
A programmable timer device for the selective change of electrical state of a remote apparatus during a time cycle comprising:
- (a) moving programmable cycle means for determining a cycle of operation of said timer device;
- (b) selectively movable operative sequence means positioned at preselected positions on said cycle means for establishing an operative sequence within said cycle of operation;
- (c) activator means, including a rotatable member moveable substantially along the axis of rotation between first and second axial positions, for changing the electrical state of said remote device in response to the movement of said cycle means when said rotatable member is in said first axial position;
- said activator means being in operative contact with said sequence means when said rotatable member is in said first axial position;
- and
- (d) skip cycle means, being sequentially contacted by said sequence means when said skip cycle means and said sequence means are in a predetermined alignment, for moving said rotatable member to said second axial position, said activator means being out of operative contact with said sequence means when said rotatable member is in said second axial position whereby said remote apparatus remains in the same electrical state during a next operating cycle.

A programmable timing device comprising:
- (a) a support member
- (b) a circular timing dial mounted for rotational motion on said support member having a plurality of spaced openings about the outer periphery of said dial;
- (c) means for rotating said dial;
- (d) first timing element removably positioned in a preselected one of said openings;
- (e) a second timing element removably positioned in a preselected another of said openings;
- (f) an actuating wheel member rotatably mounted on said support member adjacent said dial, said wheel member having a plurality of projections located in positions such that said first and second elements sequentially contact said projections and cause said wheel member to be indexed a portion of one revolution thereof;
- (g) electrical means operatively connected to said wheel member for changing the electrical state of a remote-controlled device in response to the indexing of said wheel member, and
- (h) skip cycle means, responsive to movement of said dial when in a predetermined orientation, for moving said actuating wheel member from a first position to a second position and displacing said projections out of contact with said elements.

Timer apparatus comprising:
- a dial;
- means for rotating said dial about an axis, each revolution of aid dial corresponding to a predetermined time period;
- an actuator wheel, disposed in proximity to said dial for rotation about, and translating along, an axis generally parallel to the axis of said dial;
- said actuator wheel including at least a plurality of projections disposed at a predetermined position around said wheel;
- means for biasing said actuator wheel into a first predetermined position;
- a plurality of indexing elements, cooperating with said dial, including a first extension disposed to interact with said actuator wheel's first set of projections when said actuator wheel is in said first predetermined position, to rotationally index said actuator wheel when said indexing elements are brought into conjunction with said actuator wheel by rotation of said dial;
- means, responsive to the rotational position of said actuator wheel, for controllably changing the electrical state thereof;
- means for selectively translating said actuator wheel to a second position such that said projections are removed from interaction with said elements.
