Abstract
Abstract A timer including a minutes indicator controlled to move along a stroke in two opposite directions. The dial of the timer has five apertures; the indicator has two colored zones adapted to appear beneath the dial apertures. The indicator may be positioned at a start position and thereafter moved so that the zones will pass behind the apertures to indicate time remaining for an event to occur.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
163 words
A timer including a geared movement, a resilient driving device and a minutes indicator arranged to permit counting of a limited number of minutes, the timer comprising, a control mechanism to control movement of the minutes indicator along a stroke between two extreme start and stop positions, said control mechanism being alternately operable manually in one direction or by said driving device in a direction opposite to that effected by manual operation thereof, a connecting device positioned between the movement gearing and the minutes indicator, the connecting device including means to interrupt connection between the movement gearing and the minutes indicator at the end of the stroke of the minutes indicator, whereby upon manual operation of the control mechanism the minutes indicator is moved to its start position at which the minutes indicator is disconnected from the movement gearing and upon release of the control mechanism the driving device moves the minutes indicator to thereby connect the minutes indicator with the movement gearing.
Claim 2
Dependent Claim
163 words
A timer including a geared movement, a resilient driving device and a minutes indicator arranged to permit counting of a limited number of minutes, the timer comprising, a control mechanism to control movement of the minutes indicator along a stroke between two extreme start and stop positions, said control mechanism being alternately operable manually in one direction or by said driving device in a direction opposite to that effected by manual operation thereof, a connecting device positioned between the movement gearing and the minutes indicator, the connecting device including means to interrupt connection between the movement gearing and the minutes indicator at the end of the stroke of the minutes indicator, whereby upon manual operation of the control mechanism the minutes indicator is moved to its start position at which the minutes indicator is disconnected from the movement gearing and upon release of the control mechanism the driving device moves the minutes indicator to thereby connect the minutes indicator with the movement gearing.
Claim 3
Dependent Claim
145 words
A timer as claimed in claim 1 in which the control mechanism includes a toothed sector for operating the minutes indicator, the toothed sector being connected to the control mechanism with play therebetween to permit a degree of free movement between the sector and mechanism, the toothed sector also being moveable by said driving device such that upon manual operation of the control mechanism the toothed sector is moved to a first extreme position thereby moving the minutes indicator to its start position and upon release of the control mechanism the toothed sector becomes disengaged from the driving device to effect movement of the minutes indicator by its connection with the movement gearing, said toothed sector being displaced by the movement gearing until the minutes indicator reaches the end of its stroke whereupon the toothing of the toothed sector is disconnected from the movement gearing.
Claim 4
Dependent Claim
81 words
A timer as claimed in claim 1 including a seconds indicator connected to the movement gearing by a coupling device, the seconds indicator including a reset to zerO device, the coupling device being controlled by a portion of the control mechanism, whereby upon manual operation of the control mechanism the seconds indicator is disconnected from the movement gearing and returned to zero and upon release of the control mechanism the seconds indicator is coupled to the movement gearing to rotate permanently.
Claim 5
Dependent Claim
52 words
A timer as claimed in claim 1 in which the connecting device includes a coupling device such that upon manual operation of the control mechanism and movement of the minutes indicator to its start position the coupling device is uncoupled to thereby interrupt connection between the minutes indicator and the movement gearing.
Claim 6
Dependent Claim
47 words
A timer as claimed in claim 4 in which the minutes indicator is rotatable around its stroke, the coupling device including a spring-biased movable pinion urged normally into its coupled position, whereby rotation of the minutes indicator to its start position effects uncoupling of the movable pinion.
Claim 7
Dependent Claim
88 words
A timer as claimed in claim 5 in which the connecting device includes a toothed sector adapted for meshed cooperation with the movable pinion and the connection between the minutes indicator and the movement gearing is interrupted at the ends of the stroke of the indicator when the sector toothing becomes unmeshed from the movable pinion, the driving device acting at the end of the stroke of the minutes indicator upon said toothed sector to bring the indicator into its stop position at the end of its stroke.
