ATTORNEY United States Patent 3,209,478 MULTIPLE CENTURY CALENDARS Arthur S. Burkert, 4436 17th St. N., Arlington, Va. Filed Feb. 4, 1963, Ser. No. 256,050 1 Claim. (Cl. 40109) The present invention relates to improvements in century calendars, and more particularly to a calendar which is operative through one or more century periods.

One object is to provide a calendar which can be quickly and easily set to a particular year number in a single step operation without requiring various intermediate steps or different key numbers.

Another object is to provide a century calendar which is operative for all years and does not require separate or different settings for leap years.

Another object is to provide a century calendar which when set for a predetermined year number will automatically show and indicate all of the years having identical week days of a month throughout a yearly period.

Another object is to provide a calendar of the abovementioned type in which the series of year numbers are arranged in chronological order throughout one or more century periods, and are disposed in four columns which are clearly visible, and in which certain year numbers are provided with indicating marks or dots to designate leap years so that a small change in the calendar reading can be indicated for all of the leap year numbers.

Another object is to provide a calendar of the abovementioned type which can be easily set from one year number to the next by simply shifting the week day card so that arrows or marks thereon register with the year numbers progressively.

Another object is to provide a calendar of the abovementioned type in which a slide is provided having a series of week days arranged in monthly groups, and to provide arrow markings or indicators for certain of said monthly groups of week days which when arranged opposite the correct year number will indicate and expose a twelve month calendar group of week days through a series of openings having proper indicia to represent the names of months arranged in chronological order.

Another object is to provide a calendar which is formed of a single sheet of material which can be separated into two portions by means of a weakened or serrated line to provide a slide bearing the week days in monthly groups which are adapted to be brought into registry with openings in the other portion of said sheet.

Another object is to provide a calendar of the abovementioned type in which the detached portion of said sheet bearing the monthly groups of week days is provided with additional serrated or weakened lines along opposed marginal edges to permit removal of material in these areas and form oppositely extending tongues or projections which are adapted to be slidably received in slotted openings in the major portion of the calendar sheet, the corner edges of said projections are arranged to form stops engageable with the ends of the slots in the major calendar sheet portion.

Another object is to provide a calendar which is comparatively economical and which can be printed in a single sheet bearing advertising matter or the like, and which can be quickly assembled to form a perpetual calendar by separating the sheet along the weakened zone to form major and minor calendar portions which are slidably connected so that the minor portion is movably mounted on the major portion in back of a series of openings of rectilinear form to expose predetermined week days of a particular preselected group of calendar months.

Other objects and advantages of the invention will 3,209,478 Patentedv Oct. 5, 1965 become apparent during the course of the following description of the accompanying drawings wherein:

FIGURE 1 is a top elevational view of a sheet blank used in forming the calendar showing the manner in which the year numbers and day numbers are printed thereon and illustrating the punch out areas for the various months of the year.

FIGURE 2 is an enlarged fragmentary top elevational vieW showing one end of the sheet blank and the manner in which the year numbers are printed thereon in four columns to run consecutively in a direction transverse of the sheet blank.

FIGURE 3 is an enlarged fragmentary top elevational view showing a section of the sheet blank of the calendar in the area of the upper right hand corner thereof.

FIGURE 4 is a fragmentary top elevational view of the calendar after the sheet blank has been separated along a transverse serrated weakened zone with the slide portion of the blank slidably mounted in the upper or major portion of the blank.

FIGURE 5 is a vertical cross-sectional view taken on line 55 of FIGURE 4 and looking in the direction of the arrows to illustrate the manner in which the oppositely extending projections are slidably received in a pair of parallel slots in the upper or major portion of the sheet blank, and

FIGURE 6 is a top elevational view showing the calendar slide formed from the sheet blank after the corner portions have been removed by tearing or the like on weakened serrated line areas.

In the drawings, and more in detail, attention is first directed to FIGURE 1 wherein there is shown a sheet blank generally designated 5 and having upper and lower portions providing a major portion 6 and a slide portion 7. The blank 5 is serrated transversely as at 8 to form a weakened line to facilitate easy removal of the slide portion 7 from the major portion 6.

The major calendar portion 6 is provided with a series of rectangular areas 9 which are defined by serrated and weakened tear lines 10 to facilitate removal of the areas 9 by punching the same out with the finger or a suitable blunt instrument. The rectangular areas 9 provide Windows or openings 12 and as shown in FIGURE 4 the windows 12 are arranged in horizontal rows which are offset from one another vertically and are also offset in a lateral direction. For instance, the top horizontal row of openings 12 are oifset progressively in a vertical direction in a similar manner to the second, third and fourth horizontal rows, while the openings 12 in the vertical rows are oflset from one another.

The window openings 12 are provided with marginal legends 14 arranged either above or along the side of the opening to designate year months through a twelve month yearly period.

Printed or otherwise marked in the area of the sheet 6 above the window openings 12 is a series of year dates 16 which range from 1900 through the year 2000, and the year dates 16 are arranged in four columns extending chronologically and transversely of the sheet 6 from the left to the right side thereof. The year dates 16 are arranged in groups of four or more depending upon the spacing of the window openings 12.

Marked or otherwise printed above the window openings 12 is a series of legends 18 denoting days of the week from Sunday to Saturday. The legends 18 may be letters designating the week day.

Also marked or printed in the upper right hand corner of the sheet 6 as shown in FIGURE 3 is a series of legends 20 indicating year dates which may be substituted or used in lieu of the year dates 16 for the previous century dating from 1800 to 1900. For instance, should it be desired to set up a calendar for a particular year in the 1800 to 1899 period certain of the year dates 16 can be used for the particular preselected year as indicated by the numerals 20 in the chart shown in FIGURE 3 and printed or otherwise marked on the upper right hand corner of the sheet.

The sheet 6 is provided with a pair of weakened or

serrated lines

22 and 24 which are arranged in spaced relation and extend transversely of the sheet as shown in FIGURE 1. After the lower section 7 of the sheet has been separated from the upper section along the weakened or serrated line 8, the slide section 7 is adapted to be used as a slide for the calendar. As shown in FIGURE 1, the section 7 is provided with a series of upper and lower

horizontal serrations

26 and 28 having vertical weakened lines or

serrated portions

30 and 32 to facilitate removal of

marginal corner portions

34 and 36 respectively on the left hand side of the slide section. Similarly, the right hand side of the slide section is provided with horizontal parallel weakened

line areas

38 and 40 having vertical weakened

lines

42 and 44 at the terminal ends thereof. Another weakened vertical serrated line 46 is provided and extends vertically between the

serrated lines

38 and 40 to permit removal of the marginal portions of the slide section 7 adjacent the right hand end. After the marginal sections have been removed the slide section 7 is formed with oppositely directed longitudinally extending

tabs

50 and 52 which terminate at

points

54 and 56 respectively to provide limit stops to limit the sliding movement of the slide section 7 when the same is assembled with the major sheet section 6. The slide section 7 has its upper marginal edge 50 or projection marked or printed to provide a series of spaced indicating marks 58 in the form of an arrow or similar indicator, and the indicating marks 58 are arranged to register with the year numbers 16 in the upper portion of the major sheet section 6 when the slide is assembled.

The slide section 7 is provided with a series of week day numbers 60 which are arranged as shown in FIGURE 1 and are stepped progressively upwardly and to the right in three horizontal rows, or rows which extend slightly diagonal with respect to the rectilinear edges of the sheet section 7. To assemble the slide section 7 after the marginal portions have been removed, the serrated or weakened

lines

22 and 24 are opened by a knife or the like to form slots 62 and 64. The upper slot 62 is of a length slightly greater than the length of the upper projection 50, and said projection 50 is received in said slot so that the slide section 7 bearing the day numerals 60 is arranged behind the window openings 12. The lower projection 52 is similarly received in the slot 64 and the projection 52 is of a length slightly less than the length of the slot 64. Thus, the

end edges

54 and 56 of the

opposed projections

50 and 52 respectively form stops which engage the

ends

66 and 68 of the slots 62 and 64 respectively. As shown in FIGURES 4 and the slide section 7 bearing the day numerals is mounted for transverse sliding movement so that the day numerals will appear in the openings 12 and form a calendar with the day numerals in registry with the day of the week legends 18. By moving the slide section 7 toward the right or left until one of the arrows 58 registers with a selected year number in one of the four columns of year numbers 16 the correct day numbers will appear in the openings 12 beneath the correct week day legends 18.

In the event that the selected year is a leap year, the operator may observe the

lines

70 and 72 which indicate that the months of July and August are to be substituted for the months of January and February. Suitable markings and indicia can be printed or otherwise marked on the section 6 to properly indicate alternative use in leap year periods. The series of year numbers 16 may be pro vided with marks or indications 74 opposite a leap year number to indicate to the user the different leap years so that the substitution of the July and August month readings can be used in place of the January and February readings.

In FIGURE 1 the year numbers 16 have been indicated by dash lines, but are shown in chronological order in FIGURE 2 for the purpose of clarification. Similarly, the day numbers 60 have been shown for the most part as dot and dash lines with the upper lines of each row marked to include actual week day numbers, and the lower row of each column marked to indicate the last week day of a month. In the interval between the first and last week days dash marks have been used to indicate the location of the various numerals so arranged as to appear in the openings 12 as week day numbers in proper vertical alignment with the names of the week days marked as at 18 above each of the window openings 12.

In operation, it is assumed that the section 7 has been slidably mounted in the major portion of the sheet 6 as previously described. To set up the calendar for a particular year the slide 7 is moved transversely until one of the arrows 58 registers with the preselected year number 16. After the slide has thus been moved the correct week day number groups will appear in the window openings 12 in proper registry with the day of the week legend 18. The sheet blank 5 may be formed of relatively heavy paper board such as card or bristle board of sufiicient stiffness to sustain its shape when the slide is assembled and to prevent portions of the sheet having slots from becoming mutilated. Obviously, relatively thin plastic material can be used in sheet form when constructing the blank 5, but it is preferred that the blank be formed of paper board as above described in view of the fact that the same can be easily printed and marked with the proper day of the week and year numbers.

In view of the simplicity in construction of the calendar, the same can be economically printed, and the weakened lines described therein can be easily formed simultaneously with the printing and marking operation.

What I claim is:

In a multiple century calendar, a cardboard sheet having a series of transversely arranged rows of year dates printed on the upper end of said sheet, said sheet being rectangular with the rows of year dates extending parallel with one another and with one end of said sheet, a series of rows of day numerals printed on the lower end of said sheet arranged in parallel relation with one another and the lower narrow edge of said rectangular sheet, said sheet being provided with a series of openings each of which has printed thereabove month legends designating the successive months of a year and also having printed thereon along the upper edges of said openings abbreviations designating days of the week, a weakened zone line arranged between said openings and the day of the month numerals printed on the lower end of said sheet extending transversely of said sheet and parallel to the lower short side of said rectangular sheet, said weakened zone line forming a tear zone to permit the lower portion of said sheet to be separated from the upper portion, additional weakened zone lines at the corner portions of the lower section of said sheet adapted to be removed when the lower section has been detached from the upper section, longitudinally extending tongues formed on said lower section after the corner portions thereof have been torn away to provide upper and lower parallel guide projections on said lower removed section, said upper section being provided with parallel longitudinal slots extending above and below said series of openings to permit said guide projections to be inserted therein and slidably support the lower section of said sheet formerly the lower end thereof when the same has been removed and placed in back of said upper end of said sheet, whereby slidable movement of said lower section will expose a series of day numerals for a complete month printed thereon in each of said openings, the end edges of said tongues forming limit stops engageable at the ends of said slots, and marker indicators printed on the uppermost 5 6 guide projection in spaced apart relation to permit one 2,575,555 11/51 La Plante 40l09 of said marker indicators to be moved into registry with 2,684,545 7/54 Talbot 40-109 a selected year date and expose a series of day of the 2,777,231 1/57 Bollin 40-126 Week numerals in each of said openings with the proper 2,814,139 11/57 Clare 40109 days of the Week for an entire month aligned under the 5 3,103,080 9/63 Desmond 4070 correct day of the month legends printed above each FOREIGN PATENTS opening and corresponding to the days of the Week for al months for said selected year. 106,681 6/17 Great Bmam References Cited by the Examiner 1O EUGENE R.
