Abstract
Abstract In a timer or counter for timing to a selected time or counting to a selected count, there is included digital counting means and means for creating an output signal when the counting means counts to a selected number. In this type of device, there is further provided a plurality of two state indicator elements and means responsive to the counting means for changing the state of one of the elements after the timer or counter has progressed through each of several, preselected portions of the selected number being counted.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
150 words
A timer for timing to an adjustable selected time, said timer including means for creating timing pulses at a counting rate N times the rate necessary to obtain a given number of said pulses in said selected time, said given number being a digital representation of said selected time; changeable counter means for counting to said digital representation of said selected time in repeating succession, said counter means including means for creating a signal upon each successive counting to said digital representation; means for counting said successive counting signals; means responsive to said signal counting means for creating an output signal when N successive signals are counted; manual display means for directly changing said digital representation to change the lapsed time before said output signal; a plurality of two state indicator elements and means for changing the state of one of said elements upon creation of each of said signals.
Claim 2
Dependent Claim
150 words
A timer for timing to an adjustable selected time, said timer including means for creating timing pulses at a counting rate N times the rate necessary to obtain a given number of said pulses in said selected time, said given number being a digital representation of said selected time; changeable counter means for counting to said digital representation of said selected time in repeating succession, said counter means including means for creating a signal upon each successive counting to said digital representation; means for counting said successive counting signals; means responsive to said signal counting means for creating an output signal when N successive signals are counted; manual display means for directly changing said digital representation to change the lapsed time before said output signal; a plurality of two state indicator elements and means for changing the state of one of said elements upon creation of each of said signals.
Claim 3
Dependent Claim
20 words
A timer as defined in claim 1 wherein said elements are lights and said two states are ON and OFF.
Claim 4
Dependent Claim
22 words
A timer as defined in claim 2 including means for changing said counting rate whereby the scale of said timer is changed.
Claim 5
Dependent Claim
22 words
A timer as defined in claim 1 including means for changing said counting rate whereby the scale of said timer is changed.
Claim 6
Dependent Claim
30 words
A timer as defined in claim 1 wherein said counter means is a multi-state cascade digital counter and said changing means includes means for changing the setting of said stages.
