SPECIFICATION forming part of Letters Patent No. 690,670, dated January 7, 190.2.

Application filed May 13 1901. Serial o. 60,038. (No model.)

To @ZZ whom it may concern: Be it known that I, FRANCIS C. W. STEL `TER, a citizen of the United States, residing at Astoria, Long Island City, in the county of Queens and State of New -York,have in vented certain new and useful Improvements in Calendars, of which speciiication.

My invention relates to calendars, and particularly to perpetual calendars.

The objects and nature of my invention will be fully disclosed in the following speciication, reference being had ,to the accompanying drawings, in whichl Figure 1 is a front elevation of a-oalendar embodying my invention. Fig. 2 is a horizontal section on the line c x of Fig. 1. Fig. 3 is a plan view of a portion of the movable strip employed to indicate the days of the month, showing the arrangement of figures for three months having unequal numbers of days. Fig. 4 is an elevation of the rear side of the casing with the back plate removed.

Preferably I employ a rectangular casing A of any desired dimensions in which the operating devices for moving the strip B are inclosed. The two ends f the strip B are respectively secured to spools 1 and 2, journaled to 14 appear consecutively.- In the third row the numbers 9 to 2l appear con- .secutivelv In the fourth row the numbers in bearings within the case and each having a gear-wheel 3 at one end, preferably at its upper end, as shown. Intermediate the spools 1 and 2 a shaft 4 is supported to turn and carries a gear 5, which meshes with the gears 3 on the spools 1 and 2. 'For the purpose of turning the shaft 4 a knob 6, exterior of the casing, is connected to one end of the shaft, preferably its lower end, as shown. The strip B, which -will wind onto andy olf the spools 1 and 2 when the shaft 4 is rotated, passes from the spools around guide-rollers 7 7, near the ends of the casing, and through slots 8 in the front wall of the casing, so that any desired part of the strip B may be exposed on the outer face of the casing. The space between the slots 8 will be just sufficient to expose any seven of the vertical columns of the strip B. Preferably a glass cover C will be hinged to the casing at one side and detachably secured by a suitable catch, as c, at its other side in order to protect the strip B, but at the same time afford access thereto, if necessary. To the top of the casing A may be secured anthe following is a other casing a of any desired ornamental de-k sign, .or the casinga maybe integral with the casing A, if preferred. In the Afront of the casing aan opening 10-`may be formed, and

within the casing an endless strip l1 may be supported upon two rol-1ers 12, one Aof which will preferably be extended outside the cas. ing and provided with a knob 13 for turning it. The strip 11 will have the names'bf the months printed or otherwise marked upon it, and by turning the knob 13V thename ofany monthmay be exposed through the opening 10.

The strip B is an important feature of my 16 to 28 appear consecutively.v In the fifth row the numbers 23 to 3l appear consecutively in those sections where the month has thirty-one days, there being four vacant squares at the right-hand end of the row, and in the sixth row the numbers 30 and 3l appear in the first two squares to the left, all the otherlsquares in this row be@ ing left-vacant.

In the case of. sections for months having only thirty days the numbers 23 to .30 appear consecutively in the iifth row, with five squares left vacant at the right of the row, and only the number 30.appears in the sixth row, the remaining twelve squares being left vacant. In the section for the month of February, which sometimes has twenty-eight days and sometimes twenty-nine days, I show the numbers 23 to 29 in the fifth row, leaving six squares vacant, and no number at all appears in the sixth row.

invention,and I will now particularly describe IOO It will be observed that the numbers 1, S, 15, 22, and 29, Which appear in the central vertical row of each section, are not duplicated and that all the other numbers in each section are duplicated.

One important use of a calendar is the making of notes or memoranda adjacent to the days of the month for the purpose of reminding the"owner or user of the calendar of some important matter in connection with a particular date. New there are many matters or events of which a person may desire to be reminded on the same date each yearas, for instance, birthdays, the dates on which insurance premiums are due, &c.-and one of the most important advantages of my improved calendar is that such memoranda may be made on the strip B and once made Will be a permanent reminder as long as the strip B is used. For instance, the anniversary of Vashingtons birthday occurs on February 22, and as a reminder the Word W'ashington may be Written under the number 22 in the section for February, and each year as the section for February is exposed on the face of the casing A such memoranda will appear. Again, a life -insurance premium may be due on March 3 each year, and if the words life-insurance or any abbreviation thereof be written under both numbers 3 in the section for March one or the other will always appear in view every year when the section for March is exposed on the face of the casing A. In order that such memoranda may be made, the squares of each section will be made large enough to receive both the number indicating the day of the month and such memoranda.

On the face of the case A above the strip vB there will be seven divisions or spaces d substantially equal in width to the width of the squares on the strip B, and in the respective spaces d will appear the usual abbreviations Sun.,, Moin, die., indicating the seven days of the week, and these will be permanent.

Obviously the vacant spaces on the lett of the top row of each section of the strip B and also all the vacantspaces in the fifth and sixth rows could be without the vertical dividinglines and form a continuous space in each case. Preferably, also, I shall print or otherwise mark on each section the name or the usual abbreviation of the name ofthe month each section represents, and preferably such name or abbreviation will appear twice on each section, once in the space in the top row immediately to the left of the central vertical row and again in sixth row immediately to the right of the central vertical column, as indicated in Fig. 3, and if such names or abbreviations occupy only a space equal to the width of three squares one or the other will be fully in View, no mattei' what part of the section is exposed on the face of the casing A. In such case the strip for the months in the casing a may be omitted, if desired, and I Wish it to be understood that my invention is not limited to the use of the month-strip in the casinganor to the printing or otherwise marking the names of the month on the sections of the strip B, as either one or both maybe used, as preferred.

Obviously other devices may be employed for moving the strip B to expose the proper section or part thereof on the face of the casing A, and my invention contemplates the use of any suitable means for such purpose, that shown in the drawings being illustrative only.

I am aware that a strip with figures or numbers arranged thereon just as I arrange them on the sections of my strip B for months having thirty-one days have heretofore been employed in perpetual calendars; but heretofore, so far as I am aware, one such strip has been used for every month in the year, and it is therefore obvious such strip could not be used for making permanent memoranda or reminders of events occurring annually on fixed dates in different months. Furthermore, unless some means is employed to cover or hide the-number 31 for months having only thirty days or the numbers 30 and 3l and sometimes 29, when the strip is used for February, some confusion is liable,

to occur. In my strip the exact number ot' days is indicated for each month, except for February, and to avoid confusion in this case I shall preferably have the number 29 in a contrasting color to the other numbers on the section, which will serve as a reminder that such number is necessary only in leapyears.

Having described my invention, I claiml. In a perpetual calendar, a strip having twelve divisions or sections one for each month of the year arranged consecutively, each section havinga plurality of parallel rows of divided spaces in which the numbers indicating the days of the particular month are printed or otherwise marked, the numbers indicating the days of the month in the central vertical row of each section appearing once only and all the other numbers in each section being duplicated, combined with a support for such strip having on its face marks indicating the days of the week, and means for moving said strip across the face of the support adjacent to said marks, substantially as set forth.

2. In a perpetual calendar, a strip having twelve divisions er sections one for each month of the year arranged consecutively, each section having a plurality of parallel rows of divided spaces in which the numbers indicating the days of the particular month are printed or otherwise marked, the num-A bers indicating the days ot' the month in the central ver tical row of each section appearing once only and all the other numbers in each section being duplicated, and each section having letters indicating the name of the month it is designed for on each side of the IIO vertical row of numbers and adjacent there*- to,combined with a support for such strip hav-l ing on its face marks indicating the days of the Week, and means for moving said strip 5 vacross the face of the support adjacent to said marks, substantially as set forth.

In testimony'whereof I have signed myy name to this specification in the presence of two subscribing witnesses.
