'tain new and useful Improvements in Tlme- Cards; and I do hereby declare the following to be a full,l clear, and exact descriptlon of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to an -1mproved time card for ascertainmg at a glance elapsed times between actual clock times punched thereon. This card may be used as a workmans time card, or to take records of times expended on jobs.

My im roved card is arranged with indications oi) successive clock' times on one side, and upon the other side a series of numbers are printed directly behind the signs indicating clock times respectively, which numbers are so arranged that when two different signs indicating clock times are punched, the corresponding numbers punched on the reverse side indicate by their dierence the elapsed time between the clock times. in question. By resorting to this expedient two important advantages are attained. First-the elapsed time between the beginning and end of a working period, for instance, may be ascertained instantly by a simple subtraction. Secondthe sums of any number-or" periods indicated upon separate cards may be rapidly ascertained by subtracting the sum of all the smaller numers on the reverse sides of said cards from the sum of all the higher numbers thereon. This is very useful in adding up total times spent on different days and by different men on a common job.

A card arranged in a preferred manner with the above ends in view is shown in the accompanying drawings, wherein Figure l shows the obverse side of the card, and Fig. 2 shows the reverse side thereof.

For greater convenience and to Secure the quickest results and most convenient ar. rangement, I divide the day into hours and hoursthat is to say, into periods of six minutes each. In the particular form shown ,each hour and its fractions occupy al horizontal row to themselves on the obverse of the card and the noon hour is omitted. This arrangement is of course not a necessary one. The total number of time units (in this case six minutes each) is indicated on the reverse by a succession of numerals from` one to the total (in this case 110).' Each numeral is placed behind a correspending clock-time sign, so that, on punching any sign on the obverse side, a corresponding number in the series one to a hundred and ten is punched on the reverse side.

It is to be understood that, in stating that a number is punched, I do not restrict myself to the placing of a perforation so as v actually to remove a number, either on the front (obverse) or back (reverse) ot the card. The placing of the punch mark so close to. either number punched (or to both) as to serve clearly to indicate what numbers are to be used in 'computation is within my invention.

` I prefer to place the higher numbers near the top of the reverse face, as it is natural to subtract the lower from the higher number. This is not essential.

The card shown is supposed to have been punched by a workman or by a time clock at. six minutes past seven when the workman came in, and at forty-eight/ minutes past live oclock, when he went out. The corresponding numbers on the reverse face are twelve and a hundred and nine, the difference being ninety-seven. Cates tenths of an hour, and therefore it is only necessary to point off one decimal place in this difference to get the elapsed time in hours and tenths-namely nine and seventenths hours.

It will be observed `that, although the rows of -numbers read from left to right on both sides of the card, the absolute or actual direction oi increasing succession in the corresponding series is opposite on the two sides.

It is to be understood'that it is not essential to ymy broad invention that any particul'ar clock times be selected for printing, or that those selected should be printed in any particular order or arrangement. The successive time units may be equal or unequal without departing from the scope of my broadest claim; and, of course, it is not essential to select tenths of an hour as the time unit. The total time interval may be more or less than a working day.

In my claims I refer to vertical and horizontal lines or rows of numerals, but it is to be understood that these words are employed for conveniently distinguishing This indibetween the diferent seriesreferred to, and without intending to limit myself to the placing of the numerals representing hours, or instance, in a column perpendicular to the normal bottom of the card.I In otherv words, changingA the actual direction of lines of numerals with respect to the edges of the -card would not depart from the intended scope of my claims.

What I claim is` v 1. A card having printed on its obverse -face in a vertical line a 'series of numerals indicating successive hours and, opposite each numeral of the vertical row a horizontal row of numerals diferingsuccessively by a constant difference and in regular se- Vquental order as read across the card beginning at the vertical row, all the hori-l zontal rows consisting of the same numerals in the same order and havin on its lreverse -"face numerals printed behin the numerals on the obverse face, said reverse numerals,

'forming a continuous series as read in horir zontal rows in the direction opposite to the direction of progress of the corresponding? obverse rows, and the numerals of said re-=v verse series differing successively by unity,

'fthe lowest numeral of the reverse series' being in horizontal alinement with the numeral indicating the latest hour in the obverse -vertical line, substantially j as de-v scribed. l

2. A card having printed on'its obverse 'face in a vertical line a series of numerals indicating successive hours and opposite each numeral of the vertical row a horizontal row of nine numerals in regular se.- v

quent-ial order as readacross the card beginning at the Vertical row, 'said' numerals indicating by their difference equal frac-1 tions of an hour; and having on its reversey face numerals printed behind the numerals on the obverse face, said reverse numerals forming a series continuously increasing by ,unity as read in horizontal rows in the diface in a vertical line a series of numerals indicating successive times, and oppositel each numerallof the vertical row a horizontal row of numerals diiering successively.y

by a. constant difference and in regular sequential order as read across the card beginning at the 'vertical row, all the horizontal Irows consisting of the same numerals in the Y sameorde'r and having on its reverse facefr numerals printed behind Ithose on the obverse face and constituting a group formed of horizontal rows so placed that there is a constant difference between successive nu- "merals as readin successive horizontale al-q Ways read in the same direction, said reversel numerals havin such valueswith respect to their correspon ing obverse Anumerals that 'the difference between any two of them will indicate the elapsed period between the times indicated by the correspondin obverse numerals, substantially as described.

In testimony whereof, I affix my signa` ture, `in presence of two witnesses.
