CALENDAR.

SPECIFICATION forming part of Letters Patent No. 337.478, dated March 9, 1886.

Application filed November 2, 1885 Serial No. 181,552. (No model.)

described and claimed.

In the drawings forming a part of this specification, Figure 1 shows the calendar device complete as it appears ready for use. Figs.2

Aand 3 are plans of the charts used in the calendar and containing subdivisions of days and years, and Fig. 4 is an edge view of Fig. 1 with charts removed.

Referring to the letters vof reference marked on the drawings, B is a case designed for hanging on the wall in the ordinary manner of using calendars. The face of this case bears characters subdividing the year into the number of each day in each month. At the top is an opening in the form of an inverted letter T, (shown at P.) and at a in the month of February is another opening, the uses of which openings are below described.

In Fig. 2, D is a chart bearing characters representing years in an increasing ratio, commencing with 1885, and other characters representing thedays of the week. These characiers (shown on the upper half of the chart) may be continued toward the right end of the chart indefinitely, according to the length of the chart. That the chart may not be unduly long, Ihave shown such a continuation on the lower half. To use this continuation, of course the card would be inverted and operated in the manner of operating it prior to invertion, as follows:

The chart D is inserted in the upper recess, R, of the case B, and adjusted so that the desired year is presented at the vertical part of the opening P. In the horizontal part of this opening characters representing fourteen days are presented, which are so arranged in relation to the year, the dates of the months, and the construction of the case that the actual day the year came in on will be represented by a proper character over the vertical column, 1n which figure l appears in January, and

the other days will be over the proper columns of the dates of the several months. To illustrate, take the year 1885, which is presented in Fig. 1 at the year-opening. IVe iind that this year came in on Thursday, because we find THJ over the column containing l in Jan In like manner the other dates and days for the whole year may be traced. To illustrate, take the 22d of October, pointed out by the pointer c. I/Ve find this is Thursday of the week in the year 1885-thus: Thursday, October 22, 1885.77

The dates in a recedingratio for the year and their days are as readily found as those of time not yet transpired. By sliding the chart D toward the left, presenting 1886 at the year-opening, we find that the 1st day of January, 1886, would come on Friday, the

days in the days-opening having been moved one column. Thus the days as now adjusted and the dates of the months are in proper relation for the year 1886, as they would be for any and all years to come and for any and all past years which were presented at the year-opening of the case. The exception to this which is caused by leap-years is provided for by marking "29 on the chart D at the proper position to be presented at the openinga when a given leap-year is presented at the year-opening. Toillustrate, if the year 1888 be presented at the year-opening, the lower left-hand 29 on the chart will be presented at the opening a, when the calendar would indicate that the 29th day of February, 1888, comes on Vednesday, as IVE would thenbe over the column in which 29th of February appears. The calendar is right then for January and February. The year 1888 is repeated on the chart for the last ten months of the year, and to iind dates for said ten months the chart is moved, presenting 1888, last l0 month, at the year-opening. This brings TIL77 over the first column of month-dates,in which l in March appears. As February 29 comes on W'ednesday, of course March 1 would be on Thursday; hence it is necessary that TH. be over the column in which March 1 appears. A like arrangement for leap-years is repeated on the chart every four years.

The letters A B C, &c., in the months on the case B are for convenience in knowing which day of the week a certain date is on.

IOO

To illustrate, over the column in which October 22 appears we rind L. Looking for L at the top of the calendar, We find Thursday is indicated. Thus October 22 comes on Thursday. This plan will be found more useful for other years, for the reason that in the arrangement for 1885 Sunday is in the first column ofthe month, Mondayin the second, and so on,with Satnrdayin the last; bnttakelSSG, Friday would then be in the fifth column, and hence the letter L over October 22 would indicate Friday for 1886.

In Fig. 3 a chart, D', is shown, of like arrangement tothe chart D, except the years are placed in a decreasing ratio, for the purpose ot' finding days and dates of' past years. rl`his chart is used by taking the chart D out of its recess and inserting the former in lieu thereof.

For convenience in holding the chart not in use, it is inserted in theloxverreeess, It, of the case.

To nd prier dates, suppose 1858 be presented at the year-opening of the case, We Would find that January l eame on Friday of that year, because FRJ would be over the column in which l of January appears.

The pointer c is so fnlerumed tothe case at r that it may be swung laterally and adjusted vertically, so as to set the point at any date to readily catch the eye. Thusit can beset every night to point out the next day.

l have termed the part B a ease, because it has a front and rear inclosure,with recesses between 'l'orcontaining the Charts; but, so far as the invention is concerned. the front ealen dar-Card may have the chart otherwise movably connected with it, and this card may be a plate ot' suitable material.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A calendar consisting or" a card or plate bearing associations of columns of dates representi ng months of' the year. and having openings through the plate, one for the year, one for the days, and one in the month of February i'or the date 29, anda chart movable back of said openings and bearing Characters in duplieate (representing a leapyear) for the first two months and the last ten months, the iignres 29, and characters representing days, all

so arranged in relation to each other, to the openings, and to the date columns of the months that the proper dayswill be presented over the proper date-colnrnns for a given leap.- year presented at the year-opening, and that 29 will be presented at the date-openingin the month of February, substantially as set forth.

In testimony of the foregoing I have hereunto subscribed my name in presence of two witnesses.
