SPECIFICATION forming part of Letters Patent No. 301,490, dated July 8, 1884.
1 Application filed October' B, 1853. (No model.)
To all whom it may concern:
Be it known that I, GHARLEs W. Fnos'r, a citizen of the United States, residing atPhiladelphia, iu the county of Philadelphiav and State of Pennsylvania, have invented certain new and useful Improvements in Calendars; and I de hereby declare thel following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, which form part of this specification, in which- Figure 1 is a plan or diagram of one side of one sheet of' calendar, and Fig. 2 a similar view of corresponding side of other sheet of calendar. Fig. 3 is front view of calendar set for common year, and Fig. 4 is reverscside oi' calendar set for leap-year.
My invention Whas forits object to provide a perpetual annular calendar which shall exhibit leap-years as well as common years, and which shall show in one view the number of the year for which it is set, and every day in said year. y
My invention consists of a calendar composed 4ot' two cards or sheets, each of which has tables of figures printed on both sides, and is formed with slots, which permit the gures on one side of each card to be viewedathrough the other card, as hereinafter more fully set forth.
Referring to the accompanying drawings, A and B represent, respectively, two similar cards or sheets, which have vertical slots ory openings o a and b b', and which are connected together by means of suitable fastenings, which will permit of their sliding upon one another, for the purpose hereinafter described, said fastening device being shown at T in the drawings. Each card or sheet has also one or more vertical slots, ci' b2. On one side of each card the days of the week (or the initial letters thereof) are printed in series above the slots a e b D', and on thesame side of cach card or sheet the names of the months are printed alongside of said slots, as shown. Adjacent to the small slots a? b?, and on. the same side of the cards or sheets as the name of the days and months, the numerals ofthe centuries embraced by the calendar are printed, the card B having the numerals for the common years, and the card A the numerals for leap-years, as shown ycard B are for the leap-years.
at D and E, respectively. On the opposite sides of the cards are printed tables of figures, C C' representing the days of the months. Thesertables are in vertical columns to the number of thirteen, of such width that only .seven columns of each table will be exhibited at one time through the slots a a b b when the cards are laid one over another. movement ofthe cards all of the thirteen columns, seven atatime, will be exhibited. On the same side of the cards as have the figures -for the days of the month are printed numerals indicating the units and tens of centuries. (Shown at F and G.) The columns F on card A are for common years, and the columns G on Instead of this arrangement, the entire number of years may be printed on one card, and appear through the slot on the other-thatis, instead of 18 7 showing on one card and 83 on the other through the slot, the entire numeral 188377 may show through the slot. These columns are in such position on their respective cards that they will show through the slots a2 b`2 at the same time that the tables C C show through the slots a ab b', so that the face of the calendar will show the numerals for the year 18837 forv example, for the presentyearand the numeral and name for every day in each month of the year at the same time. The columns C C' and F G are so arranged that when one of the cards is slid on the other to change the calendar from one year to another,the numerals for the days of the month will be changed at the same time. Y
The operation is as follows: Movethe cards laterally or one upon the other until the year for which the calendar is to be set is shown by conjunction of the columns D and F or E and G, for example, until 83 appears through slot a2, adjacent to 18. The same movement that produces this exhibition also brings the columns C C into such position with respect to the openings a a that the proper figures for the days of all the months are brought into lines with the names or initials of the days of the week.
Instead of having two slots a. af, a singleslot of. double the length might be employed, and in this case the columns C on each card might By alateral single elongated slot. The proportions ofthe cards would not7 however, be as desirable as where two columns and two slots are made. When the cards have been adj usted,(or the calendar set forv any particular year,) they may be held by any suitable clamp, frame, or fastening` device.
Vhat I olaim as my invention is as follows:
A changeable annual calendai- Composed of two cards or sheets, each of which is provided with the names or initials of the days of the Weelgand the names of the months on one side and with tables of the days of the months of the whole year and of the year-nu1nerals on the other side, said cards having also slots or openings through which thetables on one Cardl be in a single column of the same length as the l will show in connection with the vnames and columns on the corresponding side of the other card, said cards being secured togetherby fastening devices, and adapted to slide upon each other, whereby the entire calendar for the year may be shown at one time with the centurynumerals for that year, one side of said calendar showing common years and the other side leap-years, substantially as set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 2d day of October, 1883.
