9 BY an FM? Patented Aug. 18, 1953 UNITED STATES PATENT OFFICE This invention comprises novel and useful improvements in a calculating calendar and more specifically pertains to a rotatable dial comp-uting device specifically adapted for estimating and computing wages, compensation and the like, accruing over various periods of time.

The primary object of this invention is to provide an improved calculating device for quickly and easily determining the amounts accruing over various periods of time at various base rates of compensation.

A further object of the invention is to provide an improved calculating device in conformity with the foregoing object wherein the accrued compensation at different base rates may be easily and accurately calculated for considerable periods of time and wherein adjustments for leap years are readily made.

These, together with various ancillary objects and features of the invention which will later become apparent as the following description proceeds, are attained by the present invention, a preferred embodiment of which has been illustrated by way of example only in the accompanying drawings, wllel'fiinj Figure 1 is a top plan view of one embodiment of the invention in conformity with the principles thereof;

Figure 2 is -a vertical transverse sectional view taken substantially upon the plane of section line 2-2 of Figure l and illustrating the manner of attaching the rotatable dials to .each other; and

Figure 3 is a fragmentary enlarged portion of a part of the indicia dials of Figure 1.

Referring now more specifically to the accompanying drawings, wherein like numerals designate similar parts throughout the several views, attention is directed first to Figures 1 and 2 wherein it will be seen that the device may conveniently comprise a plurality of concentric substantially annular dials which are axially and pivotally secured to each other for relative rotation, these dials conveniently comprising disks l0, 12, M and I6 which are progressively decreasing in diameter and which are axially apertured to receive a tubular bushing or sleeve l3 through which extends a fastening bolt or the like, having a headed portion 20 disposed on the outer side of the largest disk l0, and having a resilient washer 22 secured as by a nut 24 to the outer side of the smallest disk.

The marginal portion of the outermost disk I0 is divided into a circumferential zone having a plurality of equi-distantly spaced graduations 2 26, 365 being provided although where the disk is intended solely for use in periods involving leap years, 366 divisions would be employed. It should be here noted that if desired, one side of the disk l0 and of the other disks may be provided with indicia for a regular year, and the other side for a leap year, so that the disks may be reversed to adapt the device to computing time intervals within a year of either length.

"In the divisions of the disk 40 defined by the graduations '26, it is preferred to place indicia designating the successive days of the week throughout the year, as shown at 28. However, since the last day of the year does not end upon the adjacent day of the week to the first day of the year, the sequence of weeks has been started with Monday, at l0, the last Sunday for a regular year being shown at 32 and 365th day blank at 3.4. 'In a leap year of 366 days there will of course be two blank spaces or divisions between the first day of the first week and the last day of the last week.

The edge of the second disk 12 is preferably either provided with serrations 36, as shown in Figures 1 and 3 or is printed to simulate such serrations, and these serrations are evenly spaced, either 365 or 366 in accordance with the use to which the device is to be put, so that each serration will register with the corresponding one of the daily spaces'ZG of the outer disk 10. The ,face of the second disk, that is, the annular rim of the same, is provided with radial divisions registrable with the divisions '26, and the points of each .of the serrations are disposed at the .outer end of the segment of the disk and are positioned between each pair of consecutive div si ns 2,6 of the d 0 h the iv n i the disks l0 and 12 are aligned.

The margin of the disks l4 and I6 are similarly serrated at 44 and 46 and provided with radial division lines registrable with the lines 26.

However, the marginal area of disk M has the concentric spaces between divisions indexed as at 48 with the number of each day in a week, the number of each week in a year being denoted by a numeral 50 in the space for the seventh day of that week. However, the last few weeks of a year are numbered backwards with negative concentric numerals, 52, in order to facilitate ante-dating a period of computations.

The margin of the disk 16 is provided with two circumferentially extending zones 54 and 56 in which the spaces between the division lines have indicia 58 and 60, respectively, representing the accrued compensation at $20.00 per week 3 and $1.00 per week respectively for each week of the period. Of course, other base rates could be employed as deemed expedient.

As will be readily apparent, the various radially spaced rings of wedge-shaped portions could be provided with indicia corresponding in different rates of base pay.

The manner of utilizing the device is as follows. It is assumed that the calculator is employed to compute workmans compensation for unemployement insurance, for which the apparatus illustrated is specifically designed.

Let it be supposed that it is desired to determine the compensation for a workman who was idle from January 1 to February 3 and that the workman is entitled to a base rate of $22.00 per week. The procedure is as follows. The disks l2, l4, 18 are caused to register with each other,

so that the first day of the first week, indicia 48 s of disk [4 is registered with the first day of the period, January 1 indicia 42 of disk I2. It will now be apparent that the end of the period, Feb. 3, coincides with 4 weeks and 6 days and disk [4 giving the extent of the period for which compensation has accrued.

Having placed the first division of zones 54 and 50 of disk It in registry with the first day of disk M it will be seen that at the end of the accrual period there has accrued a compensation of $97.14 on a base rate of $20.00 per week, and $4.86 on a base rate of $1.00 per week. Therefore, for a rate of $22.00 per week the compensation due is $97.14 plus 2 times $4.86 or $106.86.

The above example is calculated upon the premise that the unemployment insurance compention would not begin for 10 days, the disk M would be shifted so that the negative indicia 52 of 1 week and 3 days would register with Jan. 1. The reading and calculation above described would then be made as before.

The indicia 30 of the disk l0 would be employed when it was desired to determine the day of the week upon which a period began and ended.

From the foregoing the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary.

However, since numerous modifications and changes will readily occur to those skilled in the art after a consideration of the foregoing specification and accompanying drawings, it is not desired to limit the invention to the exact construction shown and described, but all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. A time calculator comprising a plurality of superposed disks of progressively varying diameter, a common fastener pivotally securing said disks in assembled and relatively rotatable relation, the margin of said disks being divided into equal angular intervals the periphery of the largest disc being smooth and the peripheries of the other discs being serrated to provide teeth, the intervals of one disk being registrable with selected portions of the intervals of every other disk, the intervals upon the margin of the largest disk designating the days of the week throughout the year and the intervals upon the margin of the adjacent disk designating the months and days of a year, the indicia upon the margin of a disk interposed between the smallest disk and the disk adjacent to the largest disk designating the days and weeks of an elapsed time interval.

2. A time calculator comprising a plurality of superposed disks of progressively varying diameter, a common fastener pivotally securing said disks in assembled and relatively rotatable relation, the margin of said disks being divided into equal angular intervals the periphery of the largest disc being smooth and the peripheries of the other discs being serrated to provide teeth, the intervals of one disk being registrable with selected portions of the intervals of every other disk, the intervals upon the margin of the largest disk designating the days of the week throughout the year and the intervals upon the margin of the adjacent disk designating the months and days of a year, the indicia upon the margin of a disk interposed between the smallest disk and the disk adjacent to the largest disk designating the days and weeks of an elapsed time interval, said last mentioned indicia including designations for ante-dating a period of time, the teeth of said discs being positioned at such angular intervals as to provide a tooth for each day interval.
