Abstract
Abstract The device is for accumulating the time expended by a predetermined number of workers over any selected time interval, and continuously displaying a cumulative reading. The device may comprise a plurality of separate accumulator banks each having a multiple switch array, each said switch corresponding to the predetermined number of workers, a power on-off switch, a switch for enabling counting at either regular time or time and onehalf, and a resetable display for registering accumulated time preferably in increments of a tenth of an hour. The time accumulation is continuous as long as the device is operating and whether the predetermined number of workers increases or decreases.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
90 words
An accumulator for registering time expended by one or more operating units, which accumulator comprises; means for establishing a plurality of different frequency signals, each of which signals is representative of a particular number of operating units, counting means including means for visually displaying a cumulative count corresponding to expended time, and selection means including a plurality of mutually exclusive switch means that individually correspond to a different one of said frequency signals and are individually employed for coupling a corresponding one of said frequency signals to the counting means.
Claim 2
Dependent Claim
90 words
An accumulator for registering time expended by one or more operating units, which accumulator comprises; means for establishing a plurality of different frequency signals, each of which signals is representative of a particular number of operating units, counting means including means for visually displaying a cumulative count corresponding to expended time, and selection means including a plurality of mutually exclusive switch means that individually correspond to a different one of said frequency signals and are individually employed for coupling a corresponding one of said frequency signals to the counting means.
Claim 3
Dependent Claim
28 words
The accumulator of claim 1 for registering time in man-hours expended wherein said display means indicates time expended in time intervals as small as fractions of an hour.
Claim 4
Dependent Claim
22 words
The accummulator of claim 1 including means for permitting said counting means to count at a time and one-half rate or higher.
Claim 5
Dependent Claim
31 words
The accummulator of claim 3 wherein said permitting means includes a switch for inhibiting or enabling said permitting means, said permitting means being coupled between said selection means and counting means.
Claim 6
Dependent Claim
35 words
The accummulator of claim 4 wherein said permitting means includes first and second timing circuits and a bistable device, said frequency signal being represented by a repetitive pulse which is coupled to said bistable device.
Claim 7
Dependent Claim
31 words
The accummulator of claim 5 wherein said first and second timing circuits each include mono-stable multivibrators, said first timing circuit having a longer output pulse width than said second timing circuit.
Claim 8
Dependent Claim
34 words
The accummulator of claim 6 including a first gate responsive to the outputs of both said multivibrators for passing a signal to said counting means during the period that both output pulses are present.
Claim 9
Dependent Claim
44 words
The accummulator of claim 7 including means coupled from the first timing circuit to the input of the second timing circuit for generating a second output pulse from the second timing circuit at the termination of the output pulse of the first timing circuit.
Claim 10
Dependent Claim
49 words
The accummulator of claim 8 including a second gate responsive to the output of the second timing circuit and the bistable device for passing a singal to said counting means during the period of said second output, but only when said bistable device is in one of its states.
Claim 11
Dependent Claim
23 words
The accummulator of claim 1 including means for providing a basic clock signal from which said plurality of different frequency signals are derived.
Claim 12
Dependent Claim
34 words
The accummulator of claim 1 wherein said means for establishing said plurality of different frequency signals includes means for providing a plurality of diffErent binary pulse trains each successive train of a higher frequency.
Claim 13
Dependent Claim
22 words
The accummulator of claim 11 including means for combining at least two of said pulse trains to provide said different frequency signals.
Claim 14
Dependent Claim
39 words
The accummulator of claim 12 wherein said pulse trains are synchronized on the leading edge of the pulses and said combining means includes means responsive to the trailing edge to provide a different frequency signal that is not synchronous.
Claim 15
Dependent Claim
13 words
The accummulator of claim 13 wherein said combining means includes a diode matrix.
Claim 16
Dependent Claim
59 words
The accumulator of claim 11 wherein said means for providing a plurality of different binary pulse trains includes a plate having concentric apertures, a light source disposed on one side of said plate, and a plurality of photo-detector means, disposed on the other side of said plate and periodically responsive to light passing through the apertures in the plate.
Claim 17
Dependent Claim
22 words
The accumulator of claim 1 wherein said counting means continues to count cumulatively even when another of said switch means is selected.
