cALnNDAaL f Thisinvention relates to calendars and.

more particularly to computing calendars.

y The object of theinvention isto provide a yearlyecomputing calendar so constructedy and v 5- arranged that the days may be correctly numbered andj properly placed so that each week will be complete and in which thereshall be no' distinct .lines or characters of yany kind -to show divisions ofmonths.

Another object is to provide a calendar of thisi'character inwhich the weeks are consecutively numbered and so arranged as to enable one to determine the time in weeks or days between two given dates.

With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment et the in* vention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying` drawings Figure 1 represents a front elevation of a calendar constructed in accordance withthis invention shown mounted on rollers operable to expose one or more months as may be desired;

Figure 2 is a similar view showing a diferent mounting of the calendar with astrip having the months thereof slidable through a plate having an opening to expose the desired period; f 1

Figure 3 is a perspective view showing still another arrangementr of the calendar;

Figure Lt is an enlarged front elevation o one of the sheets used in theform shown in Figure 3; and

Figure 5 is a frontelevation of a portion of the strip employed in the form shown in Figure 2. i f

In'Figure 1 the calendar which constitutes this invention is shown in the form of a strip 1 constructed of paper, celluloid or other suitable material and which has arranged on oneV tace thereof months of the year arranged consecutively, the days being so numbered and placed that each week will be complete except the irst and the last as the case may be. There are no distinct lines or characters of any kind to show the division of the month but the months are preferably distinguished by using a variety of colors for the respective months or to print the first day of each month with afspecialfcharacter or color to designate the beginning oi a new month, as is shown at 11 in Figure 1 in which the Roman numeral I `is used i'orthis purpose.k A

The.strip 1 issecured atI its opposite ends to rollers o and V6k which are mounted yon ypintles 7 and Sjournaled in suitable lframes indicated at 9. These pintles 7 and Bare each provided fat one end with a knurleddisl; l0

`to. facilitate turning thereof iwhenit iside- ;sired to change the calendar.

' lnthis arrangement the strip 1 which carries the consecutively arranged months and the days of the month, the latter is placed in blocks 2` tormedby intersecting lines 3 and L respectively.

The months may be arranged in either ver tical or horizontal position, the horizontal arrangement being shown in Figures 2 and 5 Vwhile the vertical arrangement is shown in the other figures.

In Figures 3 and 4 the calendar is formed as a pady 12 showing three months arranged on each page or sheet 13 with the prevailing month preferably arranged inthe center of the sheet as shown at 14.

In`Figure2 a trame or plate 15 has an opening 16 formed by transversely arranged slits 17 and 18 spaced longitudinally apart a sufficient distance to eXpose between them one month carried by the strip 19 which is thread ed through the frame and which contains on itA the consecutively arranged months with the days of the month as is shown in Figure 5.

Disposed along one side of the opening 16 transversely of the frame or vertically thereof are the names of the days of the week as shown at 20. In this form of the invention and in that shown in Figures t and 5 the names of the days need only appear once for the entire year. c

Arranged along one edge of the strip 19 employed in Figures 2 and 5 or along one edge of the sheet 13 used in Figures 3 and 4 are the numbers of the weeks arranged consecutively rom 1 to 52 by the arrangement and numbering of the weeks from 1 to 52, the

plans for computing time in weeks or days between two given dates may be worked out.

It is to be understood of course that the calendar may be used so that the entire year or either 13 and 14 months may be exposed or only two'or three months may be exposed or any desired number of months;

In the use of this calendar thenumber of Weeks between two given dates may be read-y joining ot the several months without any line .or characters oi any kind showing a division with the numerals indicating the days of the month arranged continuously tor the consecutive months and yet so placed that the num-` ber ot weeks between the given dates may be readily ascertained at a glance and the number of days between two given dates may be readily ascertained with a very little calculation.

A .calendar embodying a plate, Vsaid plate having spaced parallel slits defining a supporting surface between the slits, said plate having the names of the days of the weeks printed adjacent to one of the slits, a strip having a plurality of lines formed thereon and delining spaces to receive numbers representing the days ofthe month, said strip having the names of the months printed above certain groups of spaces, and said strip adapted to move through the slits to provide a calendar.

In testimony that I clai-mthe foregoing as my own, I have hereto affixed my signature.
