' IMPRovEMENT iN PERPETUAL couNTiNc-'Hous'E CALENDARS.
A f Specification formingpart of Letters Patent N0. 173,655, dated February 15, 1876; application iiled To all whom it 'may concern: y
Be it known that I, FREDERICK W. 'LUTT- GEN, of zthecity, county, and State of New York, haveinvented ka new and usei'ul Im-A provenient in Movable Gard-Calendars, of
which the followingisa speciication:
`The inventiony relates ,to that class of calendars in-Which the cards maybe shifted perpetually, or in which the material Vemployed provides'for a greater period of time than the time that is presentedto view on the face of the same.
The object of my invention is, first-to make the material employed answerfor a greater period ot' time; second, to render it unneces- 'sary to manipulate such calendars as much as heretofore; third, to make Vit possible to present vagreater period of time to view; fourth, to make a reduction in bulk possible, yet presenting a calendar-in the most simple form, retaining all the qualities of convenience, neatness, andintrinsic value.
Figure 1 is a .plan view of my improved calendar. Fig. 2 is a plan Vof a moditiedform'of vthe same. Fig. 3 is a plan of akey to the ,but they may be arranged in a pack, only showing the current month in front, -ii' so desired. These tablets are twenty-eight, or more, counting both sides, and the numbers 'of the days are arranged in the order of the changes thattake place during a period of twenty-eight years, which is the time in which the changes repeat.V F represents a key, to be printed on the back of the case as the most convenient place for it, or it may be in tablet form Within the case, by `which to ascertain how to adjust the tablets 4forl the diEerent years.
This key shows in the columns a the day of the month of some particular days, say
Sunday, for each month for twenty-eight years,
, -November 13, 1875.
the years being represented in columns b'b.
These dates show which tablet is to be' takenfor any month for any year, and the tablets are accordingly numbered at E vE to correspond withthese numbers.
Fig. 1 represents a calendar With twelve. tablets, and Fig; 2 represents one with eighteen.
The leading features of .novelty in my invention consist: First, in.'numbering the monthly tablets, A, as represented in drawing at E E', (the figures in the right are the numbers of the monthly tablets presented in the face, and the smaller figures inthe left are the number and index to the tablet provideduin the other side, each tablet being thus utilized for two months for economizin g in the number of tablets.) Second, in the key F, by means of which the cards are selected and put in place for a calendar of any year, (should it be desired to have'the calendar of any year not stated in this key, add or deduct 28, or the multipleyof 28, to or from such year until you nd one of the years stated in this key, and the calendar ofthe year required will correspond with the calendar of such year found,) and the day of the week of any date is easily found. The numbers of the monthly tablet, as the numbers in the key, correspond with the date of one ofthe Sundays of the month. Third, the
4improvement of presenting to view 6, 12, or
1S months, orany other period of time exceeding one month, in a movable card-calendar. Fourth, in a movable calendar printing monthly tablets Without the name of any month thereon. Fifth, the case Gr, Withits com'- partments for the different cards. Sixth, the frontplate H, for a monthly calendar, with twelve or more movable cards on the face, and an even surface, and for a calendar of a greater period. v
The leap-'years are indicated in the key F by the numbers 21 to 28 in February column.
'The numbers may also be made to represent any other day of the week than Sunday without changing the principle of my invention, and other numbers or characters may be -substituted. y l
For convenience, I take 21 cards, printed on both sides, (though 18 will suffice for an animal perpetual caleudar,) to present at once 1'8 months to View, or to present the important advantage of changing, toward the close of a year, one-half of the calendar to the first months ot' the succeeding year. f
The plate B I propose to keep in place by any simple method suitable to the nature and material used,`(such as clasps, slides, hinges, spring-catch, &c.,) and in applying the calendar to` articles of'furniture, brackets, ornaments, &c.f, the back plate may be dispensed with, and the partitions placed directly upon the articles, but the partitions may also be connected with thefront plate. The calendar may also be cylindrical in form for pedestal's of mantel ornaments, &c.
In a perpetual monthly calendar but 14 cards would be required iorthe months, printed on both sides.
ted time, say two years, some cards may bev cconolnized, as the key Will indicate.
The days of the week are not changed, but are permanently printed, Sac., on the case,
always commencing the Week with Sunday as the most convenient form.
. The usualeconomy in card by' printing the 29th of February in red may also be practised in my invention.
The numbers for the years I also prefer to.
Having thus described my invention, I claim as new, and desire kto secure by Letters Patent-' As a new article of manufacture, a perpetual counting-house calendar, l consisting of the transferable monthly tablets A, printed without the name of `any month, the case G, with its twelve or more compartments, and the per-r f forated plate H, with twelve or more openings for the monthly tablets,`and having the name z of a month formed'upon the face ot' the plate,
one adjoining each opening, as and for the purpose specified.
