To 'all/whom it may concern.' i Be it known that I, KENNETH M. MonnisoN, of iMiniiea olis, county of Hennepin,

and, State of Minnesota, have invented ce1'- A tain new and useful Improvements in Time` Calculators,."of whichthe'following is a specification.

My invention relatesto machines for ascertaining the numberA of days between two given dates and the. primaryl object of thev invention is to provide adevice by means l o f whichA at a glance aperson can guickly! and easily ascertain the number -o Tdays from a certain date in one month to a datev in a subsequent month Avwithout any calculation or addition whatever'.

A- further 'object is to provide ainachine by means of which the date on which a note drawn for a certain vlength of time can be ascertained at. a glance, and whether the note matured on. Sundayor a legal holiday.

A further object is to provide a date computing machine which may be utilized as a perpetual calendar.v Gther `objects ofthe invention will ap- 'pear from the following detailed description.

yals

The invention consists generally in the constructions and combinations, -all'as hereinafte;` described and particularly pointed out in the claims. I the accompanying drawings forming part of this specification, Figure l is a plan view of a` date computing. machine embodying my invention, Fig. 2 is a longitudinal, sectional view of .the same, illustrating the -mechanism for shlfting thescomputing belt,

showing a portion of the transparent plate with the slotted paper stripmounted thereon, .Figjl isV a similar view, showing aplate having a portion of its surface transparent-, tlirogh which the vfigures on the may' be read and a portion opaque and 'aring thegures representing the days 'of the month. v.

In' the drawing, 2 presents a suitable casing, preferably of metal, having an open top to reeeive-a lass plate 3 whichrests upon stops`4: and 1s voverlapped on two sides and onelend preferably by stationary flanges 5 and 6, whileat the other Iend a removable flange 7 is rovided which will allow the insertion of t e plate into the casing and hold it securely therein. A plate 8 of suitable material, preferably Celluloid, has -ends adapted to slide between the flanges 5 -and 7 and the ends of the glassplate, and is` provided with a series of holes .9 to receivescrews l0 which, when removed, allow the transverse adjustment of the plate8 back a longitudinal opening 11 therein and at'the top and bottom of this opening I arrange letters forming abbreviations of the days of the week. The letters composing the.

abbreviations are preferably vertically arranged, there being, ofcourse, seven verti- "cal rows across the middle portion of the plate aj-t theends of` the opening 1l, as indicated in Fig. l. The upper row of abbrevia- 'tions isused for setting the machine and' in the computations for each year, while the lower row at the bottom of the opening in the plate 8 is used only in computing the days from a .certain date in one year to a date in the next year, .which will begin-on a day 'one day later than the preceding year. On each side of the opening l1 .theplate 8 is'iiivided intospaces designated for the names of themonthsof the year, therebeing twelve spacesl .on-each side of the ope`n,

`ing 11, with the names' of the months lindicated therein, beginning vat the top of the spaces and extending to the bottom thereof.

0n the undersideof the glass plate 3 I .providea sheet 1241iz suitable material, prefand forth across the casing.. This plate has i lmonth to be set beneath the letters representing that day at the top of the sheet. As indicated in the figures, there are siX adjustments of the plate 8 from side to side, to allow the plate to be adjusted for accurate computation, regardless of the day on which the first month of the year begins.

`Within the casing 2 is a frame l'having rolls 1G and 17 journaled therein, around which an endless computing belt 18 passes.

The roll 17 is adapted to slide in slots 19 in said frame and is pressed outwardly by springs 2O which operate to push the roll 17 outwardly and tension the belt 18 and insure sufficient friction between it and said rolls to cealed.

cause its endwise movement when the rolls are revolved. The spindle 21 of the roll 16 is provided with a finger grip 22 by means of which the roll -16 is revolved to move the computi-ng'A roll forward and back, lengthwise of the machine. Beneath the frame 15 is a shaft 23 having pinions 24 secured thereon in transverse guideways 25. Rack bars 26 are preferably mounted on the underside of theframe l5 and. mesh with the teeth ofthe pinions. 'The shaft 23 has la finger grip 27. When this shaft is revolved' the frame 15 will be moved bodily back and forth across the casing of the 'machine 4-to i shift the position of the computing beltwith respect to the stationarv glass .platefand the movable month and day :indicating plate 8.

Referring now to Figs. 3 and 4't1ie puting belt 18 is shown provided Withfa series of longitudinal columns 28. There are thirteen'of these columns,an arbitrary number, and the plate 8 is capable of transverse adjustment over six of these columns on each side of the center col-umn andthe open- 4ing 11'in the plate 8 is of sufficient width to expose seven of these columns on the computing belt at one time,'while the remaining six columns 0f the computing belt are con- The computing belt is provided with figures representing the days of the year fromv 1 to 365, and 'these figures are duplicated upon opposite sides of the middle column of the, belt, and each horizontal row of figures on the belt running transversely thereof will read consecutively and the figures in each horizontaly row reading from the top to the bottom ofthe machine will be seven units greater than the figures in the same column respectively of the horizontal row above. The duplication of the figures in the horizontal rows is represented in F ig. 4, in which it is shown that the figures of the last six columns on the computing belt of each horizontal row are repeated in thejfirst six columns of the row beneath'. This duplication of the 'figures n the computing belt allows for its adjustnient back and forth across the machine to. adapt it for the variations or changes in the days ofthe week on .which the successive years begin and the adjustment of the plate 8 of the'maehine allows the operator to' easily and quickly-adjust the machine at the beginning of the year, setting the abbreviation of a'certain day opposite the figure' representing the first day of the-month on the stationary glass plate beneath.

As' indicated in Fig. a, there are two groups of numerals,`rea ding transversely of the computing belt, running from 1 to 365.

.The groups I will designate generally by reference letters A and B. lThe beginning of the first groupv is represented in the lower part 0f the figure and the ending of the first group is represented at the top of the figure, thisarrangement being brought about by the passing of the computing belt around the operating rollers. For convenience in the use of the machine, I prefer to inclose the numerals 365, representing the last 'day of the year,-of the first group A, in a circle, though any arbitrary mark might be placed in the column adjacent to these figures for the same purpose. Then, in setting the machine for computation, the numerals 365, inclosed in the circle, are adjusted opposite` the numeral representing the day of the-month fromwhich it isfdesired4 to make the4 computation.

l' II Fi 31 have illustratedl the device adfijpus'ted"forcomputing the days in the yearl l11913, in Iwhichthe vmoll-'tirf--January begins .on Wednesdayfiniis indicated by the adj usteet 8 opposite the stationary.A

ment of the As figure 1 onthe glass plate. JWhen this has been done the computing belt is moved until` the gures 9865, vinclosed in the circle, stand opposite the letters representing Wednesday, the first day of' January, 1913. The machine is then set for the proper computation of days between January 1st and any subsequent date in that year. For instance, referring to Fig. l, tbc number o'f days between Jalfarv 1st and the eleventh of May is desired. The figures 365 in thecircle being` opposite the numeral representing the first day of January, by 1min.'- ning down the vertical left hand 'column Itire operator will find the numerals represent-.nig the eleventh of ,May andabove these numerals the figures 130, the nuniber'of days from January 1st to May 11th. By shifting the notarse B belt 'and moving the gures 365 shown in' the circle opposite any other day' in any other month of the year, the number of days from that,d'ate to a subsequent date in the same'yearcan be easily and'quickly ascer-l tained.

In Fig. 5 the numeral 365,1 inclos'ed in the circle or brackets, is shown set 'opposite the numeral 7, representing the seventh of December 'oa certain yea-r, and it isdesired. to ascertain' the number of d'aysfbetween that .date and the fifteenthV of February of the next year. The computation will be carried through the'- second group B, and by referringtothe' lower row' of letters onthe plate. 8, We will find that the fifteenth of February falls on Sunday,I and thatit is days from' the .precedingsventh' of December. This lower row of abbreviations is only used when the computation is from 'a date in one year toa dlate in the 'following year. lVhen the clerk figures this computation for a note due the fifteenth of February,he will at once ascertain that this date 'falls on' Sunday and that the note matures the da'y before, or the day after, as the `statute may require. .In the same manner, if the note is dated the seventhof December and runs ninety days, he can at a glance ascertain that it will` fall due on Saturday, the seventh of March. l y Suppose it is 'desired to ascertain the number of days between April12th and Septems ber 21st of the me year. (See Fig. 6.) `The computing bel is moved until the figures 365 inc-losed in the bracket-s 'or circle are` oppositethe numeral 12, 'representing the twelfth of April. Then, running dovvn the column to the figure representing September 21st in the same yea-r, the operator will see at" a glance that there are 162 :lays between the two`dates. v

. As Aindicated in Fig. 7, I prefer to designate holidays by some distinguishingmark, such as a circle around the figure representing that date on the stationary plate, so that in making a computation, the clerk, if he :finds a note falls 4due on that date, can indicate the maturity as of the preceding, day,cr lthe day after, if the State law requiresl 'In Figs. 8 .and 9' different adjustments of the transversely movable plate 8 are s'h'oWn, which maybe utilized to adaptthe machine for lea-p year dates. For instance, referring` to Fig. 8, February is' indicated as having 28 days, the rst of March beginning' on Thursday, vbut if the year should happen to be a leap'year, then the operator would move the plate 8 one notch toward the left, as shownin 9, bringing the numeral representing the first dayof March Abeneath the heading for Friday, and then for all Leclroning from a data prior to the first ofM'arch to a date -following the-first `of March .for that year, the operator -would add Que day'to his total pins 10. and sliding the 'plate transversely on fthe glass plate until vthe abbreviation of the ,day ofthe'week at the top of the plate 8 is opposite the numeral representing the first day of January of` a certain year. This plate 8 is only adjusted once for each year. -'The computi-ng belt is then moved transversely until the' numeral inclos'ed in the brackets,

orsome arbitrary mark in thespace With the numerals 3,65,"7 is oppositethe day of the 4month from whiclrcomputation is desired,

and the longitudinal as Well as the transverse movement of the computing belt allows this numeral Withthe arbitrary mark asso-l ciated therewith to be moved not only trans versely of the opening 'through' the pla-te Y8, but'also lengthwise thereof to permit computation from any date inany month of the year'for .which the machine is set.

In Figs. 3,' 8, 9,-10 11 have shown a calendar sheet 3 provided with calendar numerals arranged in thirteen columns run- Yning lengthwise ofthe sheet, corresponding 'to the number and arrangement of columns on the computing table belt, and these cal! endar numerals are repeated upon each side of the middle column oft-he series .in the same manner' as the numerals representing the days of the-Week are repeated on the belt. For instance, the calendar z*numerals will run consecutively `from roW'to row-on each side of the middle column, each `nu- ,meralof a row being' seven units greater than the' corresponding numeral of therow above on each side of the middle column. The plate 8 will normally conceall all 'but seven of these columns, the calendar dates 'exposed through the opening in the plate i representing the days'of the month vof the current year, and when the plate is adjusted transversely additional'coluinns of calendarv dates will be exposed and a corresponding number of columns previously exposed'will be concealed to adapt the machine for com putation in another year,

In Fig. 12 the glass plate' S is shown provided with a paper sheet glued or otherwise rfastened to the underside of the plate, with.

'or' the month, between which bars trans-r parent areas are provided in the L glass ranged beneath said calendar sheet and hav- -ing numerals representing the days of the Sli days' from a date represented by a calendar vside of said central column being repeated through which the iigures on thecomputing belt may be seen.
