(SALEM SPEUIFIGATIOII forming part of Letters Patent No. $86,618, dated April t, 1905.

Application filed April 23. 1904. Serial No; 204.518.

To all whom it DMZ/y concern:

Be it known that we, JAooB BALL, a resident of \Vaterloo, and ROBERT E. RITZ, a resident of Berlin, in the county of lVaterloo, Province of Ontario, Canada, subjects of the King of Great Britain, have invented certain new and useful Improvements in Calendars; and we do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in what are commonly known as perpetual calendars; and it consists incortain features of novelty in the combination and arrangement of the parts and numerals comprising such calendar whereby a series of relatively fixed and relatively movable numerals maybe so combined in one general structure as to provide means whereby such structure is available for use as a calendar for a predetermined period of years as indicated by numerals in year-charts arranged thereupon and made a part of the calendar.

A further feature of our invention is the combination, with elements adapted to prod uce a calendar available for use during what are herein called common yearsthat is, the years other than leap-years-with movable connections whereby the same general device is adaptable for use in indicating the days of leap-year.

The object of the invention is to produce in a unitary device such a combination of parts provided with fixed and movable digits that the same device may be utilized as a calendar for a considerable period of years to be de termined in advance by the limits to which the numerical arrangement is carried out.

In the annexed drawings similar characters of reference indicate like parts in all the views where used, wherein Figure l is a general face or plan view of a calendar provided with the invention, the calendar disclosed in Fig. 1 representing the current year 1904, together with year-charts, hereinafter described, to render the same available, in conjunction with other features subsequently developed herein, for use for the period up to and including the year 1950 and also indicating calendars for the years 1850 to 1900, inclusive. 2 is a face or plan view of what is hereinafter designated as a base with a slidable member especially available for use in or during lcap-years connected therewith. Fig. 3 is a detached detail view of a movable face-plate adapted to be used in conjuntion with the base of Fig. 2, upon which face-plate are shown yearcharts. Fig. l is a sectional view taken on the line i a of Fig. 1. Fig. 5 is a section taken on line 5 5 of Fig. 1. Fig. 6 is a view taken on line 6 6 of Fig. 2, and Fig. 7 is a section taken on line '7 7 of Fig. 1.

in the subjoined description of our invention certain arbitrarily-sciected titles are given to different parts for the sake of clearness and brevity as follows: The base-sheet or major sheet, which is shown in detail in Fig. 2 with a slidable member at the upper lefthand corner thereof, (which member is connected therewith,) is hereinafter termed in the specification and claims the base, said base comprising the necessary digits for ten months, preferably arranged. to exhibit the necessary day-numbers for all the month-see tions from March to December, both inclusive, as hereinafter described. The twelve series of numerals shown in full in Fig. 2and partly exposed in Fig. 1, which numbers serve to indicate the month-days numerically and approximately chronologically as to series of sevens, are hereinafter called monthcharts. The slidable member connected with said base in the exemplification of the invention shown being located at the upper left hand portion of said base and carrying there on the necessary digits for the days of two month-sections, as January and February, is called the slide. The outer 'or perforated face-plate shown in plan view in 3, which face-plate has shown thereon the charted arrangement of numerals for the several. years for which the calendar is meant to be available and has the sight-openings to disclose the required digits for the several months, is called the face plate, The charted arrangement of numerals shown beneath the numerals 1850 to 1900 and bcneuth tho numerals 9290i to 'iSSiO uro hereinultor culled the your-M1 arts. \Yithout turthor doscription or pi! oi? dooro uorouiutter used roiercncv to tho "husof month cha s "sli1lo,

Referring now to Z 'l or detsilod description of the faceplate, it will he noted that ited to gr! o LIL plate 1 are also provided slots 12, two of such slots being shown, through which slots project studs or buttons 13, as shown in Fig. 1, which are available for the purpose of holding said face-plate 4 in position slidably upon the base 1, so that theopenings 11 in said face-plate may be shifted longitudinally of the projection of said slots 12 for the purpose of exposing different series, including portions of each month-chart, before referred to, such exposure exhibiting only the required numerals of each month-chart for any particular month of a given year and the size and configuration of such openings 11 being such as to expose only the proper numbers available to be utilized during any predetermined year. In addition to the buttons 13 other buttons 14, four in number, being disclosed in Fig. 1, are provided for the purpose of holding the faceplate slidably engaged with said base and with the slots 2, before referred to, in such base, whereby a more perfect connection of the base and face-plate is provided.

Year-charts.-The year-charts (designated by the letters A and B and best shown in Figs. 1 and 3) comprise series of numbers in blocks of four, followed by a blank space where permissible, though, as disclosed, the year-chart intended tobe available for calendar purposes from 1850 to 1900 commences with and 51, followed by a blank space, after Which appear the numerals 52, 58, 54, and on the top line of such chart, followed by a blank space on the next lower line with numerals 56 to 59, inclusive, with blank space, and the numeral 60. In the line including the numbers 50 to 55, inclusive, but one blank space appears. In the line including the numbers 56 to 60, inclusive, two blank spaces appear. In the next line six numbers and one blank space appear.

in the following line five numbers and two blank spaces appear, &c. It will be noted that the numerals commencing with 52, including each fourth year thereafter, are shaded for the purpose of indicating that such years are leap-years, and on the occurrence of such years the leap-year shift should be applied to the slide 5 to render the calendar available for use to correctly indicate the proper arrangement of days and numbers for the months of January and February, though for other months the shift need not be made. Correspondingly the year-chart B, which includes 1901 to 1950, both inclusive, is divided into parallel lines comprising the numbers serially arranged in blocks of four followed by a blank space, with each fourth number shaded, commencing with 4 and ending with 48 in the disclosure of Fig. 1. It will be noted that in the period from 1850 to 1900 the numbers commence with 50 and end with the two ciphers, the 19 being understood, while in the year-chart B the numbers 19 are omitted, such chart beginning with the number 1 and ending with the number 50. As shown in Fig. 1, as before suggested, the calendar is arranged for the present or current year, which is a leap-year. Hence the slide 5 is shifted, as shown in the full lines in Fig. 2, so as to disclose the numerals Q9 through the orifices 7 in said slide and also the letter L through the orifice 6 therein. It will also be noted thatin the slot 15 appear the letters "A. D. above both charts A and B, which letters are intended as an index or gage to determine the degree of shift which shall be imparted to the face-plate in moving it over the base 1. If it is intended to render the calendar available for use in the year 1905, the face-plate shall be shifted, as indicated by the arrow in Fig. 1, to bring the numeral 5 under the letters A. D., whereupon, as will be evident, the first numeral disclosed on the January month-chart would be 1, which would indicate that the year 1905 commenced on Saturday, said numeral l being the first numeral on the upper line of the month series for the month of January. However, the year 1905 does" not commence on Saturday, and it will be evident that the slide 5 should be shifted to the right one notch, so as to disclose the letter C through the orifice 6, whereupon the numeral 1 on the upper line will disappear beneath the face 16 of the face-plate, and the first number exposed in the opening for January Will be 1 on the second line of that month series, thus exposing for the month of January, 1905, four complete rows of sevens, commencing with 1 and ending with 28, and also the numerals 29, 30, and 31 on the bottom row of that series, and the other month-days will be arranged in regular order, so as to render the calendar available for use during the year 1905, which is a common year, the shifting of the slide 5 having covered the numerals 29, and following thenumeral 28, exposed through the face-plate, will appear the opening 7 on the lowest line, beneath which will be a blank space on the base. If the calendaris to be used for some other yearas, for example, 1910, which is not a leap-year-the slide 5 remains in the same position as when in use for 1905, the faceplate is shifted to bring the numeral 10" below the indicating-letters "A. D., and the first day of 1910 will be Saturday, January 1, followed by the usual numbers in series of seven for that and the succeeding months, reading vertically of the numbers exposed through the said openings 11.
