To all whom t may concern:v

Be it known that I, Omron P. EVANS, a citizen of the United StatesLresiding at the city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Lapsed-Time-Calculating Machines, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to -the accompanying drawings, forming part of this specification, in which- Figure 1 is a plan view of the base member of my improved device. l

Fig. 2 is a vertical longitudinal sectional view through the same.'

Fig. 7 is a vertical sectional view through a modified form.

Fig. 8 is a detail view of another modified form.

This invention relates to a new and useful improvement in lapsed time calculating devicesemployed for the purpose of determining the cost of labor on a given job of work at a certain rate per hour depending upon the length of time spent on the job.

The object of my present invention is .to simplify the construction ofdevices of this character, cheapen the cost of production thereof, and to makethe same accurate and dependable in determining the cost of labor on any given job and at a predetermined rate per hour, the number of hours or time spent on the job being known,-in this way saving mental and aritmetical computations usually resorted to in the cost departments where pencil and paper are generally employed in making the computations.

In the drawings, l indicates a base or bed plate (see F ig. 1) at the righthand end of which is a table like extension 2 whose upper surface is countersunk for the reception of a removable card 3, said card being held in position by spring clips 4. In this card, in suitable lined spaces arranged in horizontal and vertical columns, are previously ascertained calculationsv of hours and fractions of hours of time multiplied by a given rate per h'our.

In the instance illustrated in Fig. l, the rate per hour is sixty cents (gb) and according to my present disclosure the hour is divided into fractions of five minutes or one-twelfth hour. It is obvious, however, that this scale could be changed according to the design of the maker by dividing the hour into ten multiples,- or such other multiple as occasion requires.

The card 3 illustrated in Fig. l also has a day rate printed thereon, preferably at the righthand corner, to indicate the cost per day of a given number of hours for a certain piece of work; for instance, if the work was started Monday and finished on Wednesday, three full days of nine hours each, multi lied by the day rate of five dollars and Forty cents ($5.40.) the sum total of the cost of the job would be s ixteen dollars and twenty cents ($16.20) this amount being determined atthe beginning of the morning of the neXt succeeding working day when time on the job is usually taken and ascertained. For Saturdays or half holidays, the same computation is carried out wherein five and one-half (5) hours is computed as constituting a half-days work. VThis day schedule is also employed to determine the amount applicable to a piece of work begun Vearly on one day and finished later on another. The day rate to be used in` conjunction with the shifting apparatusis as follows: Taking for instance a piece of work begunat 9:10-Monday morning and finished at 2:35 Wednesday afternoon, the computation would bevmadeby combining the value of the time in whole days which had elapsed together with the value of the time in hours or minutes. The hour and minute value for the first partial day is determined by the shifting apparatus hereinafter explained. The value of the whole days elapsed is determined by referring to the day schedule in the right hand corner of card 3.

In the example under consideration, Tuesy day is the only full day, and hence the cost of the work done on this day is to be added to the cost of the work done on the partial days, z'. e. Monday and llifednesday. The cost of the work done on Wednesday is ascertained in the same way as the cost of the partial days work on Monday is ascertained.

As the work in the example under consideration was commenced at 9:1 0 a. In. Monday, we will assume, for purposes'of illustration, that work on this particular job was stonned at 12 m. and thirty (30) minutes allowed for lunch, work again commencing at 12:30, and stopping at 5 p. m., the qu1tting time. y

From 9: 10 a. m. to 12 In. is two hours and fifty minutes, the cost of which, at sixty cents (609i) per hour, is $1.70. From 12 :30 p. m. until 5 p. m., four hours and thirty minutes, at 60g/5, would amount to $2.70, and the indicator 13d hereinafter described would the thirty (30) minutes for lunch, or lost time, the figure to the right of 13i on the scales 13b or 13c would point to $4.40, the cost of labor devoted to the job on Monday, on which seven minutes were spent at the rate of 60 per hour. l

In computing the work-done on the job on Wednesday, we will assume that work started at 7:30 a. m. and was stopped at 12 m. for lunch, this time being four and one-half hours; from 12:30 to 2:35, two hours andl live minutes will have been spent on the work and this added to the four and onehalf hours devoted to the job in the morning, would make six (6) hours and thirtyfive (35) minutes, devoted to the job-on Wednesday. At sixty cents (60) an hour, this would amount to $3.95, thus the total cost of the job for the partial days spent thereon on Monday and Wednesday, and the full day spent thereon 0n Tuesday, would be $13.75.

Space or spaces may be provided for ten hour days, eight hour days, or such other hours as may be required in different institutions as constituting a days work.

There are provided, of course, a set of cards for each calculator ligured on the' basis of different rates per hour, such as various A factories require, and these different cards are employed preferably by grouping vthe number of men working at the same rate per hour and calculating their time by the use of the same card and then changing the card to calculate the nextgroup working at a different rate per hour.

It will be seen in this connection that not only is the cost of labor on a given job readily obtainable, but the pay-roll can at the same time be made.

Preferably tothe left of the table 2, just above described, the surface of the base or bed plate 1 is formed with grooves or kerfs 6 which are arranged at right angles to each other, said other atthe lower right hand end of the bed plate. Opposite the transversely disposed point to $4.70 and, after deducting l (7) hours and twenty (20) grooves or kerfs intersecting each grooves or kerfs are numbers in the table 7 I indicating hours from 7 a. 1n. to spectively. These numbers read from right to left, asshown, while opposite the ends of the longitudinally disposed grooves or kerfs is a minute scale 8, reading upward from zero in multiples of live minutes to fifty-live minutes.

The numeral 9 indicates a starting indicator comprising a support also provided with transversely and longitudinally disposed grooves or kerfs 10. This sup ort at its lower or forward edge is providbd with a scale 11 containing numbers opposite the transversely disposed grooves or kerfs 10 reading from left to right to indicate the hours from 7 a. m. to 5 p. m.

For the sake of distinction, I prefer to distinguish the numbers in the scales '7 and 11 by making the p. m. numbers in heavy black type and the a. m. numbers in open face type, or shading that portion of the scale containing the p. m. numbers, as shown on the drawings.

It will be observed that the numbers on scale 11 are reversely arranged with respect to the numbers on scale 7.

12 indicates a scale at the righthand side or edge of the indicator support containing minute indicating numerals from zero opposite the uppermost longitudinally disposed groove or kerf 10 in multiples offive minutes downwardly, to fifty-five (55), which latter is opposite the foremost longitudinally disposed groove or kerf 10. These minute 1ndicating numerals on scale 12 are reversely arranged with respect to the minute indicating numerals on scale 8.

Two of the edges of the supporting member 9, preferably the foremost and righthand edge, are flanges 9a which the kerfs 6 of the base plate and thereby securely hold, against accidental displacement, the said support element 9 in its adjusted position.

Thenumeral 13 indicates a finish indicating element whose body portion in the form of a block is provided with depending angularly disposed projections 13a which are designed to fit in the kerfs or grooves 10 of the supporting element 9, thereby fixing the indicator in its dilierent adjusted positions and holding it in such adjusted ositions against accidental displacement. he iinish indicating element comprises the body portion, just above described, and extending from the right hand end thereof is a stem portion from the extremity of which extend angularly arranged scale portions 13b and 13c in opposite directions, while in line with the stem portion is a pointing projection 13d.

The scales on the oppositely extending portions 13b and 13`indicate minutes reading upwardly in multiples of five minutes,

5 p. m. -rethe purpose of these scales being to enable v the operator to deduct-any fraction of an hour from the amount indicated b lthe pointer 13. The object in providing t e indicator with two sets of scales 13b and 13c is to enable either scale to be employed in making deductions for lost time in the event that in the adjustment ofl the parts one of scale 13c Acannot be read in connection with any number on card 3. Allv of the deductions in scale 13b, however, are opposite numbers -on card 3, and thus are readable in connection therewith. v I

Referring now to Fig. 4, we will assume, in describing the operation of the device, that the workmen started on a particular job at 9 :10 a. m.; the supporting element 9 is adjusted so that its indicating arrow A points to the intersection of the grooves or kerfs 6 in the bed plate 1 opposite or inline with the numeral 9-in the a. m. portion of the hour scale 7 and the numeral 10 oposite the longitudinally disposed groove or erf in the minute scale 8. This adjustment of the indicator supporting element 9 represents the time at which the workmen commenced. Assuming that the particular job, the cost of which is being ascertained, was finished at 2:35 p. In., the indicator 13 will be adjusted so that its arrow B is located at the point of intersection of the kerfs or grooves 10, leading from the p. m. numeral 2 in scale 11, and the kerf vleading from the minute indicating numeral 35 in scale 12. This will locate the pointer 13d so as to indicate three dollars and twenty-five cents ($3.25)., being the labor cost of the particularjob being computed for the time lapsing from the indicated time of starting said job to the indicated time when said job was completed. This computation is based on thcrate of sixty cents (6045) per hour. If the workman on the'particular job under consideration had lost forty minutes from the job for lunch, or for any other reason, the operator would refer to scale 13b or 13,

. and accept the numbers to the right of the numeral 40 as the actual cost of the job, in this instance, two dollars and eighty-five cents (932.85).v

If the particular workman on the job underconsideration receives a different rate per hour for his labor, of course a different card 3 would be employed for use inconnection with the indicator to compute the cst, z'. e., the length of time spent on a particular job multiplied by the rate per hour.. If the workman devoted so many days time 62o i B 'and so many hours and minutes toa given j ob., the' days time could be ascertained from the table at the upper righthand corner of the cardv 3, to'. which wouldbe added the I hours and minutes.

Instead of having the indicator supporting block 9 and theindicator 13 arranged thereon,pdetachably and separately connected, I may form the grooves or kerfs 6 and l10` in the shape of a T, as shown in Fig. 7 and providerollers 15 and 16 on the lower faces of the indicator 13 and the movable block 9 so that the parts 9 and 13 may be ad- \justed relative to each other andto the bed plate l'by sliding the sameinposition. This will avoid the necessity of-bodily lifting the parts 9 and 13 for purposes of adjustment and prevent loss of said parts by rendering l it unnecessary to detach them during the operations of adjustment thereof.

While I have shown the bed or base plate 1 and the indicator supporting element 9 as being provided with grooves or kerfs leading from hour to. minute scales whereby it is possible to adjust the supporting element ment 13 on the supporting element 9 and hold them against accidental displacement, it is obvious that a bed plate 17 shown in Fig. 8, having a fiat unkerfed surface provided with lines 18 would answer the same purpose as the grooves, and if desired, holes or openings 19 could be provided in the bed-plate 17 into which could be fitted projections 20 extending from the coperating time of starting element 21 and in this way avoid accidental displacement of the parts.

-The time of starting element may similarly be provided with openings 22 and lines 23 with which openings coperate pins 24 on the time of finishing element 25 and which, as in the construction above referred to, carries the cost -indicating scales and pointer on the end of its connected bar 26.

What I claim is 1. In an apparatus of the character described, the combination of a base having hour and minutevscales arranged at angles to each other, a movable starting time indicator angularly adjustable on said base and also having hour and minute scales arranged at angle to each other, a finishing time indi- '9 on the bed plate and the indicating elecator arranged on said starting time indicator and capable of angular adjustment thereon, and a computing table containing numbers representing the cost of labor at a given rate per hour with which said inish- A ing time indicator coperates.

I arranged at angles toeach other, a finishing time indicator arranged on said starting time indicator and capable of angular adjustment thereon to indicate the time of finishing.,r the Work, and a computlng table containing numbers representing the cost of labor at a given rate per hour wlth which said finishing time indicator coperaties,

said finishing time indicator being provided with a minute deduction scale vfor indicating the tota-l cost of labor less a given number of minutes to be deducted from the time lapsing between beginning and nishing the work.

3. In an apparatus of the character described, the combination of a base having hour and minute scales arranged at angles to each other, a starting time indicator angularly adjustable on said base to indicate the time of beginning Work, said indicator also havin hour and minutescales, a nishing time indicator arranged on said starting time indicator and capable of angular adj ustment to indicate the time of finishing the Work, and a computing table containing numbers representing thel cost of labor at a given rate per hour with Which said finishing time indicator coperates7 said indicator being provided With oppositely disposed deduction minute scales for the purposes described.

Intestimony whereof I hereunto afiiX my signature, this 22nd da of June, 1918.
