Timer with visual indicator for period of operation

Claim 2

A timer comprising a switch; a manually adjustable control for actuating said switch; said control having a set position and an unset position; motor driven means for releasing said control from its set position to provide a timed period of actuation of said switch; first visual indicator means movable with said motor driven means to show the propeR termination time for a desired period of switch actuation; said control being movable relative to said motor driven means when said control is in its set position to determine the time at which said control will be released from its set position; and second visual indicator means movable with said control; said first and second indicator means together showing when the desired period of switch actuation has been set.

Claim 3

The invention as set forth in claim 1 wherein said timer includes a motor driven clock for showing the time of day; said motor driven means being connected to said clock for movement thereby so that said first indicator means will be moved by said clock through said motor driven means to show the time subsequent to that shown by the clock when a desired period of switch actuation should end.

Claim 4

The invention as set forth in claim 1 wherein said first visual indicator means includes a member rotatable with said motor driven means and having indicia means exposed to view for showing the proper termination time of a desired period of switch actuation; and said second indicator means is rotatable with said control so that the setting of the desired period of switch actuation will be shown by moving said control to bring said second indicator means into angular alignment with said indicia means of said first visual indicator means.

Claim 5

In a timer including a switch; a manually adjustable control for actuating the switch, the control being longitudinally movable between a set position and an unset position; motor driven means cooperating with the control to release the control from its set position when the control and motor driven means are in a predetermined angular relationship, the control and the motor-driven means being interconnected for concurrent motor-driven rotation when the control is in its unset position and being freed for independent manual rotation of the control and motor-driven rotation of the motor-driven means when the control is in its set position, so that the degree of manual rotation of the control in its set position will determine the period of rotation of the motor-driven means necessary to reach the predetermined angular relationship and thus determine the period of switch actuation; first visual indicator means movable with the motor-driven means to show the proper termination time for a desired period of switch actuation; and second visual indicator means movable with the control, said first and second visual indicator means together showing when the desired period of switch actuation has been set.

Claim 6

In a timer including a switch; a manually adjustable control for actuating the switch, the control being longitudinally movable between a set position and an unset position; motor driven means cooperating with the control to release the control from its set position when the control and motor driven means are in a predetermined angular relationship, the control and the motor-driven means being interconnected for concurrent motor-driven rotation when the control is in its unset position and being freed for independent manual rotation of the control and motor-driven rotation of the motor-driven means when the control is in its set position, so that the degree of manual rotation of the control in its set position will determine the period of rotation of the motor-driven means necessary to reach the predetermined angular relationship and thus determine the period of switch actuation; first visual indicator means movable with the motor-driven means to show the proper termination time for a desired period of switch actuation; and second visual indicator means movable with the control, said first and second visual indicator means together showing when the desired period of switch actuation has been set.

Claim 7

The invention as set forth in claim 4 wherein the timer includes a motor-driven clock for showing the time of day; the motor-driven means being connected to the clock for movement thereby so that said first indicator means will be moved by the clock through the motor-driven means to show the time subsequent to that shown by the clock when a desired period of switch actuation should end.

Claim 8

The invention as set forth in claim 4 wherein said first visual indicator means includes a member rotatable with the motor-driven means and having indicia means exposed to view for showing the proper termination time of a desired period of switch actuation; and said second indicator means is rotatable with the control so that the setting of the desired period of switch actuation will be shown by moving the control to bring said second indicator means into angular alignment with said indicia means of said first indicator means.

Claim 9

A timer comprising a switch; a control for actuating said switch, including a manually adjustable shaft longitudinally movable between a set position and an unset position; motor-driven means mounted for free rotational movement about said shaft and cooperating with said control to release said control from its set position when said shaft and said motor-driven means are in a predetermined angular relationship; said control and said motor-driven means being interconnected for concurrent motor-driven rOtation when said control is in its unset position and being freed for independent manual rotation of said shaft and motor-driven rotation of said means when said control is in its set position, so that the degree of manual rotation of said shaft in its set position will determine the period of rotation of said motor-driven means necessary to reach the predetermined angular relationship and thus determine the period of switch actuation; first visual indicator means rotatable with said motor driven means to show the proper termination time for a desired period of switch actuation; and second visual indicator manes rotatable with said shaft, said first and second visual indicator means together showing when the desired period of switch actuation has been set.

Claim 10

A timer comprising a switch; a control for actuating said switch, including a manually adjustable shaft longitudinally movable between a set position and an unset position; motor-driven means mounted for free rotational movement about said shaft and cooperating with said control to release said control from its set position when said shaft and said motor-driven means are in a predetermined angular relationship; said control and said motor-driven means being interconnected for concurrent motor-driven rOtation when said control is in its unset position and being freed for independent manual rotation of said shaft and motor-driven rotation of said means when said control is in its set position, so that the degree of manual rotation of said shaft in its set position will determine the period of rotation of said motor-driven means necessary to reach the predetermined angular relationship and thus determine the period of switch actuation; first visual indicator means rotatable with said motor driven means to show the proper termination time for a desired period of switch actuation; and second visual indicator manes rotatable with said shaft, said first and second visual indicator means together showing when the desired period of switch actuation has been set.

Claim 11

The invention as set forth in claim 7 wherein a sleeve is mounted for free rotation about said shaft, said motor-driven means being mounted on said sleeve for rotation therewith and said first visual indicator being mounted on said sleeve for rotation therewith; whereby said first visual indicator rotates with said motor-driven means.

Claim 12

The invention as set forth in claim 8 wherein said motor-driven means includes a motor-driven member loosely mounted on said sleeve and a finger projecting from said member longitudinally of said shaft; a second member is connected to said sleeve for movement therewith, said second member defining an opening therein, said finger projecting through said opening so that said motor-driven member and said sleeve rotate together.

Claim 13

The invention as set forth in claim 9 wherein a third member is connected to said shaft for rotation herewith; said third member defining a surface for engagement with the distal end of said finger to restrain and control in its set position and an aperture in said surface to receive said finger when said motor-driven member and said shaft are in the predetermined angular relationship thereby to release said control from its set position.
