cnnnnnan,

Application filed July 10,

To all to 710m it may cmwer'n:

Be it known that l, LEWIS J. BRABANT, a citizen of the United States, of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Improvement in Calendars, which invention is fully set forth and illustrated in the following specifications and accoinpai'iying drawings.

The object of this invention is the making of a simple mechanical device comprising three to five simple fiat parts of cheap material adapted to slide upon one another into indicated positions in which there will be produced to the vision a calendar in the usual and accepted form, with proper number of days and coincidence of dates with days of the week, of any month in any year, as desired; and to make such device useful besides for reference purposes to an extended span of years, also as a current calendar for ten or twelve years.

A further object of the invention is to provide an easily operated and easily understood device, so arranged that when any selected month designation is brought into ohserving position in connection with a table of lunar month day designations, the correct table of excess month day designations for the selected month will he properly positioned with respect to the table on": lunar month day designations.

In the drawings,

Figure 1 is a plan view of the improved calendar with parts broken away,

Figure f2 is a similar view with the front or mount removed,

Figure 3 is a plan view of the plate carrying the year and week day designations,

Figure l is a side view of the same,

Figure 5 is a plan view of the part carrying the table oi lunar month day designations,

Figure 6 is an end view of the same,

Figure 7 is a plan view of the part carry-' ing the month designations and the excess day tables, v

Figure 8 is a partial plan elevation showing an alternate arrangement, Figure 9 is a plan view of the covering slide.

The improved calendar consists of three principal parts, which are preferably of celluloid, but may beott any other suitable material, and the three parts are mounted to slide upon each other. These parts are in 1919. Serial No. 309,880.

the form of plates, indicated at A, and C respectively. The plate A is mounted to slide verticallyon the plate B, and the plate B is mounted to slide laterally on the plate C, the plates A and B being mounted in any suitable form of guide, as for instance the character of guide shown at 14L and 15 in.

Figures l and 6, the saidguides being formed by overlined fianges'on the edges of the plates and C, and any suitable means may be provided tor facilitating the moving. The plate A is provided on its forward face with a'plurality of vertical lines,

dividing the said face into columns, and in these columnsat'tlie upper partot the plate there is arranged a number of month indications, as shown at 1. At the lower part of the plate a plurality of tables 2 of excess days over a lunar month are arranged, in such manner'that when any month in the upper table is in'obsei'ving position, the

proper table of excess days will be in corre'ct position with respect to the tables of the lunar month day designations. The plate 13, Figure5, has tables 3 of the month day designations. and has apertures through which the tables of excess days on the plate A may be observed. The plate B also carries an aperture 5 through which month designations on the plate A may be observed.

The plate 0, which is the mount or front of the calendar has an aperture 6, of sulfici'ent size to expose a table of month day's.

Above this aperture there is a table 7 of week day desi nations, and an aperture 8 above said table, through which the month designations 1 may be observed. Above such apertureS, the plate Chas a plurality of vertical columns, designations 9.

A slide 10 is mounted to move transversely of the plateC, on thebackthereof which contain year between guides 11, and this'slide has a notch the year designations are arranged; It will be evident that by moving the slide later ally, as indicated by thearrows' in Figure 2, any desired designation thetable 9 may be exposed." Instead of notch, the slide 10 may have a transparent portion ot' a size eorrespondingto the notch." The slide 10 is so arranged that the upper edge thereof is at the upper edge of the table 7 of week day designations. In order to extend the operation of the calendar, that is to make it a perpetual calendar, additional year designations may be arranged upon a plate 13 which may be secured to the face of the plate, C over those year designations of the table 9 which are above the upper edge of the, slide 10. When the plate 13 is'so arranged, with the year designations on the rear face, as indicated in Figure 1, only one year designation will be exposed. This plate 18 may be secured to the plate C in any usual or desired manner, as for instance by l'iingiug it to the plate 0 to be folded down over the year designations on the said plate. Referring to Figure 3 it will be seen that there are year designations 9 below the aperture 8. These year designations are shown by reversing the slide 10, so that the notch 12 is at the lower edge of the slide.

Referring to Figure 8, it will be seen that instead of the plate 13 I may use a plate 16, whose ends overlie the ends of the slide 10, and are secured to the guides 11. This plate is notched deeply on its under face at the aperture 6 of the plate C, so that the notch 12 of the slide 10 is fully exposed when the said notch is in the notch of the plate 16. The plate also has a central extension overlying and concealing the year designations of the table 9 above the upper edge of the slide 10.

The table of day designations on plate B is arranged in 13 columns and 6 rows. Numerals are worked in the columns as follows, beginning in the top row, seventh square, the figure 1, followed consecutively by 2, 3, 4, 5, 6 and 7 in the square below 1, the figure 8, the squares to its left being numbered consecutively downward to 2 and the squares to its right consecutively upward to 14:; each additional row being provided with numerals reading consecutively upward from left to right, and bearing relation to the figures in that above it in that each figure is seven more than that in the square immediately above it, the figures in any row ending with 28 and the remaining squares left blank. Apertures 1 are provided by cutting out the squares immediately. below those containing figures 22, 23 and 24 wherever they occur, through which numerals following consecutively from 28 upward are revealed.

It is apparent that any seven adjacent columns in the combined date group may be read consecutively and from row to row downward from 1 to 28, 29, 30, or 31 respectively, according to the adjustments of the rear slide A, and by concealing all parts of the group except seven vertical adjacent columns and disclosing only seven, as for instance through a rectangular aperture as provided in part 0 (Fig. 3), such consecutive group of figures is disclosed to the vision.

Part B is adapted to fasten in rear of part C (Fig. 3) by grooves, rivets, or in any other practicable manner so tl at it may be slid or otherwise moved horizontally into any of the seven possible positions by which its columns will correspond and register with the seven colun'ms of C and the date numeral 1 will register with any of the,

days of the week marked in such seven columns, when also one of the designations of months on A sl'iowing through apertures 5 (Fig. and S (Fig. 3) may be brought to register in column with the designation of any year numeral marked in such seven columns.

The

apertures

6 and 8 of the plate C are rectangular, and equal in width to 7 columns and laterally bounded by the same vertical lines. The upper aperture, 8, is of such height and positioned that when the calendar is assembled it coincides with the aperture 5 in part B, (Fig. and in seven possible positions of B reveals to the vision seven adjacent columns of the month r group 01 part A 1g. 1). l he lower aperture, (5, is of height equal to the six rows .1

of the main d te group of part B, and is so positioned that when the calendar is assembled its horizontal lines coincide with the horizontal lines of such date grtnip and there is revealed to the vision through it seven complete columns, of the date group, with figures reading consecutively in the usual form of monthly calendar.

Having described my invention, 1 claim:

1. In a calendar, a slide having apertures, a second slide movable vertically thereon.

and having thereon a month group with the months classified in rows according to the number of days in them, each row of months having corresponding thereto a specially arranged and positioned row of figures, the distance between and relative position of corresponding rows being similar in each case so that they may show coincidentally through the apertures in the first named slide, said first named slide having thereon a date group of sufficient numerals to form a twenty-eight day month so that when a row of months show through one aperture, there will appear at further apertures following the figures 28 appropriate numerals extending the date group to 29, or 31, as appropriate to the months shown, substantially as described.

2. In a calendar, a laterally moving slide having apertures and marl-red with a date group and hearing at its rear a vertically movable slide marked with rows of the: names of months classified in rows according to the number of days in them, one row of such months appearing at av time through an aperture with corresponding rows of figures appropriate to the months shown appearing through other apertures, and a mount having an aperture coinciding in position and height to the aperture showing rows of months with rows of numerals along its horizontal edges representing current years, so that the names of the months may be brought to register in column With and immeditely adjacent to said year numerals so that the name of one month and the numeral of one year registeringin the same column may be disclosed to the vision through the apertures of the mount, and means for concealing the months and years, said means having an opening through which one month and one year will be visible.

In a calendar, a mount having a horizontal aperture through which may be seen one row of months at a time of a month group classified in rows, and rows of year numerals along the horizontal edges of said aperture, a slide mounted to move laterally on the calendar front, said front having guides in which the ends of the slide are held, the slide being of a height suflicient to cover the apertures and rows of numerals, and having at the middle of one of its long edges a recess of such depth and width as to reveal the name of one month and the numeral of one year, and reversible to bring the recess .at the upper or lower edge so that the slide may be adjusted to show numerals in either row, substantially as described.

4:. In a calendar, a plate having a table of week day designations, and a table of year designations above the week day designa tions and with the year designations and the week day designations in vertical columns, a second plate having tables of lunar month day designations arranged in vertical columns, said plate having guided movement laterally on the first named plate to permit any selected column of said tables to be brought into vertical alignment with any selected column of the year and week day designations, and a third plate having a table of month designations and tables of designations of days in excess of a lunar month, said plate being movable vertically with respect to the second named plate and the tables of the saidlast named plate being so arranged that when a selected month is brought into a position in alignment with a selected column of year and week day designations and between such designations, the correct table of excess days for the month will be in proper position in the table of month day designations.

5. In a calendar of the class described, a plurality of plates having guided sliding movement on each other, sundry of the plates having openings through which data on other of the plates is visible, said plates carrying tables of designations of years. months, week days, lunar month days and excess days so arranged on the plates that when by sliding the plates upon each other a selected month designation is brought into a prescribed position with respect to a selected year designation, and a selected table of lunar day month desigi ations is brought into proper position with respect to the week day designations, the designations of the days for the month in excess of the days of the lunar month will also be in proper position with respect to the table of lunar month day designations. I

6. In a calendar of the class described, a plate having tables of lunar month day designations, a second plate having guided movement of the first plate, and provided with tables of month and of month day designations in excess of a lunar month, and so arranged upon the plate that when a selected month designation is brought into observing position above the tables of the first plate, the correct table of excess month day designations will be properly positioned with respect to the table of lunar month day designations.
