Abstract
Abstract A meter beater timer is provided which alerts the user when a pre-determined time interval has expired so that he can return to the meter and deposit additional coins if necessary. Unlike previous timers, the user is reminded to set the timer when he withdraws the ignition key from the ignition. The key is attached to a key ring and to a key chain which retracts into the timer housing when the key is removed from the ignition depressing a plunger which sets off an alarm. An electronic version and a mechanical version are provided.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
160 words
A meter beater timer, comprising in combination: (a) a timer housing; (b) a interval timer, contained in said timer housing, wherein said interval timer is set to a preset time interval and counts backward from said preset timer toward zero; (c) an alarm, contained in said timer housing; (d) a stop button operatively coupled to said alarm, wherein said alarm sound when said interval timer has reached zero and wherein said alarm is turned off by depressing said stop button; (e) a retractable chain connected to a key ring, such that said retractable chain is extended by the weight of said housing when a key attached to said key chain is inserted into an automobile ignition, and retracts into said timer housing when said key is removed from said ignition thereby releasing tension on said key and said key chain; and, (f) means for activating said alarm when said key is removed from said ignition and said retractable chain retracts.
Claim 2
Dependent Claim
160 words
A meter beater timer, comprising in combination: (a) a timer housing; (b) a interval timer, contained in said timer housing, wherein said interval timer is set to a preset time interval and counts backward from said preset timer toward zero; (c) an alarm, contained in said timer housing; (d) a stop button operatively coupled to said alarm, wherein said alarm sound when said interval timer has reached zero and wherein said alarm is turned off by depressing said stop button; (e) a retractable chain connected to a key ring, such that said retractable chain is extended by the weight of said housing when a key attached to said key chain is inserted into an automobile ignition, and retracts into said timer housing when said key is removed from said ignition thereby releasing tension on said key and said key chain; and, (f) means for activating said alarm when said key is removed from said ignition and said retractable chain retracts.
Claim 3
Dependent Claim
18 words
A meter beater timer, as recited in claim 1, wherein said interval timer is a mechanical stop watch.
Claim 4
Dependent Claim
75 words
A meter beater timer, as recited in claim 1, wherein said interval timer further comprises an oscillator which produces pulses which are initiated by the actuation of a start button; a resetable counter with logic which can be set to begin counting backward at the desired number of minutes and sends an initiation signal to said alarm; and a display which indicates the number of minutes and seconds which have elapsed since said count began.
Claim 5
Dependent Claim
70 words
A meter beater timer, as recited in claim 1, wherein said means for activating said alarm when said key is removed from said ignition, comprises a plunger which activates said alarm, and a cradle comprising a circular notch in the side of said timer housing, such that when said retractable chain retracts said attached key chain is forcibly nested into said cradle, forcing said plunger inward thereby activating said alarm.
