TIME AND WAGE COMPUTER.

Specification of Ifetters Patent.

Patented Mal'. 3, 1914.

To all whom it may concern Be it knownz that we, TH'oMAs'J. FALVEY and RoBsoN D. CALDWELL, respectively of Needham, in the county of Norfolk and State of Massachusetts, and of Salem, in

ythe county of Essex and said State of Massaof work or operation, and the cost of wages for the same. l

The device is arranged with provision for indicating at once, the time elapsed between the beginning and ending of any job and the amount of wages expended for the same at anyA particular rate per hour, and these results are obtained without any mental calculation, thus saving the mental work andV time necessary to subtract the time of beginning from the time of ending a job to determine the lapse of time and then vmultiplying that time, which may be and usually is, an odd number of hours and minutes by the wage per hour which the workman is paid.

It is a common practice in manufacturing establishments for each workman to be provided with a card for any piece of work or operation which he'performs, andeonwhch the hour and minute of beginning and ending of the work is stamped. These cards are turned in to the c ost ldepartment and the labor element of the cost of the work there computed. This computation ordinarily in-` tions instead of the commonly used sexagesimal subdivisions.

Ourinvention enables both results,.-that is, of the elapsed time and monetary value of the time to be read at a glance, without the necessity of any computation and without requiring the time to be indicated in any unusual manner such as by the decimal system.

.Our invention also provides for readily indicating the value of any particular length of `time in money at any required rate of pay per hour.

In the drawings, Figure 1 represents a plan view of the computing device constructed to 'embod the essential features of our invention. ig. 2 represents a cross-section of the apparatus shown in Fi 1. Fig. 8 1s a fragment-ar plan view o one end of the apparatus with the cover removed.

The essentials of the invention and of the apparatus in which the same is embodied,

'comprise three or more scales designated respectively, a, b and c, of which thescale a is marked with characters or graduations indicating the hours and divisions of the hours of the working day, the second bears marks showing successive intervals of time beginning at zero and increasing cumulatively to the end of the day, and the third shows the money value of each of the time intervals of the two preceding scales at a certain rate per hour. v)We make the scale c shiftable and provide a series of scales of similar character of which any one can take the place of the others, and the Figures on which are calculated to show the values of the time intervals for a large number of differing wage rates per hour.

Preferably the apparatus consists of a box or casing d having a cover e on which are the scales a and b. The scale c shows through an orifice f in the cover, and is printed upon a tape or band g, which in the present specific embodiment of the invention, is attached at its ends to two rolls h and z', on which it is wound, and assing over a fiat guide y' under the orifice It will be noted that the scale a is provided upon a bar k which slides longitudinally in the cover e, and bears characters lieginnin with the commencement hour forv work an continuing with ures representing ten-minute intervals up tothe closing hour. Here the hours between 7 a. m. and 6 .-m. are denoted on thepscale, but it is levident that any other time limits may be employed and other intervals than those of ten-minutes may be made to appear on the scale. The scale b, which is beside the scale a, has figures in parallel with those of the scale a, showing consecutively the same intervals of time from zero up to ten hours, that being the. time from 7 a. m. to 6 p. m. with the noon hour from twelve to one deducted. There is a stop Z which extends' across the end of the box and bridges the slide Ic. This slide preferably has a series of small holes or recesses m, one opposite each of the time indications in which a pencil or other pointed instrument may be inserted to serve as a means of moving the slide. When the slide is moved until the instrument brings up against the stop Z, the figures on the scale opposite the particular hole engaged by the instrument is parallel with the zero on the scale Z), and fall of the other figures of the two scales are in parallel.v

In using the device the stop iS employed to locate the starting time at Which a workman begins a particular job. The cost clerk inserts his pencil or pointed instrument in the hole opposite the figure showing the beginning time, and moves it until it engages the stop Z. This brings the commencement time opposite the zero markvof the scale E. Then' following down the scale a to the hour of ending the job, and reading across tothe corresponding ligure in the scale Z), the clerk learns at a glance the total elapsed time spent on the job. For example, the instrument is shown in the drawings as set to compute the cost of the job which is. begun at eight oclock in the morning. Now suppose that the workman completed the job at eleven-twenty a. m., the number below the large figure 11 on the scale, has been found. Upon reading across to the adjacent ligure inthe scale b, it is seen thatl the total time spent was three-hours and twenty-minutes. Supposing, however, that the work was not finished until after the noon hour, and completed, say at one-forty p. m., reading from the gure 40 below the large figure l, it appears that the total working time spent was four-hours and forty-minutes, the noon hour having been deducted. At the same time the figures in the third column, which are parallel with those of scale Z9, can be read, showing the amount of wages paid for the work. rlfhe wage rate for which the column c, shown in Fig. 1, is calculated as eleven cents per hour, the figure 1l appearing at the bottom of this scale. The cost ci' the job which was in the previous example considered to have terminated at eleven-twenty, shows that the cost in wages was thirtyseven cents, while the work whichI terminated at one-forty, cost iiity-one cents. The other scales on the band or sheet g are similarly cal "e et 'the ten-minute int hour between the and the highest paid workmen. Of course where'the scales a and b are expressed in other time intervals than ten-minutes the, figures of the scale 0 are also calculated for other intervals, those of each of the scales being of course lin correspondence.

It will be evident that by the use of this device no mental calculation on the part of the cost clerk is required, and that the results can be determined in a very short time, it being necessary only to nd the time of commencement 'of the Work on the scale, move the scale until this time is opposite the stop,`@an'd then find the time of ending the work. By placing the edge of 'a card or rule across the columns at this latter point the elapsed time and wage value 4may be instantly read and noted down. By reason of the fact that the stop Z is provided to automatically arrest the movement of the slide when the lcommencement hour Ais brought opposite the zero of the scale Z), no time need be expended in adjusting the scale to bring these marks opposite one another. Moreover, no great amount of time is required to lind the product between the lapse of time and the Wage per hour paid to the Workman, for the scale c, which shows the time valuesv for the required rate per hour, may be quickly brought into view under the slot f by simply turning one of the rolls ZL or z' to carry the tape g past the slot. The result is then determined by reading across to'the figure which appears on the same line withY the time designated on the scale a, showing when the work was ended. Thus all the time required for reading this apparatus is that necessary to ind the numbers on the scale a, make a return movement of the hand until it is arrested by the stop Z, and make a single adjustment of the tape g to bring the desired scale or column c into view. The time Jfor making a number of readings may' be still further shortened by having the cards of the workmen so sorted that all those for each wage rate are together. This reduces the number of adjustments `necessary and that of the number of diilerent cards tor workmen.

As a convenient means for adjusting the tape g and scale c, the rolls 71, and z' are provided with knobs n and 0, whereby they may (be turned by the user of the instrument. rlhese rolls are conveniently held in any position by a light friction exerted by the springs p and g which are illustrated in Fig. 3 as being` arranged to bear against the ends nosemso a small proportion of the total number of scales of said series,.said series of scales being mounted with capability for displacement laterally to cause-any one of the series to appearbeside the first scale, and the firstmentioned scale being movable endwise,
