CALENDAR.
SPECIFICATION forming part of Letters Patent No. 482,929, dated September 20, 1892.
Application filed J' uly l2, 1892. Serial No. 439,826. (No model.)
To all whom it may concern:
Be it known that we, CHARLES H. RENDELL and EDWIN S. PINNEY, citizens of the United States, residing at Tulare City, in the county of Tulare and State of California, have invented new and useful Improvements in Calendars, of which the following is a specification.
This invention relates generally to calen- (lars, and particularly to that class thereof known as perpetual calendars.
The object of our invention is to providea simple and efficient calendar of this description which, in conjunction with an exceedingly-simple'table, can be operated to produce a complete calendar for any year either before or after Christ, and according to either the old or the new style of computation.
Our invention consists in the peculiar construction and arrangement of the various parts, all of which will be fully described hereinafter, and pointed out in the claims.
In the drawings formingapartof this specitcation, Figure 1 is a face view of our improved calendar set for the year. 1892. Fig. 2 is a vertical section of the same, and Fig. 3 is a detail view of the sliding card detached.
In carrying out our invention we employa sheet of card-board A of suitable size and thickness, and in the center of the same produce one or a series of vertical slots a. In
the drawings we have shown three such slots,
that being the number usually employed. Upon each side of the slots a are designated the days of the year arranged horizontally, according to the month, and vertically, according to the days of the week, as most clearly shown. The designations are upon each side of the slots, and it will be observed that while the months run from'left to right upon the right of the slots they run from right to left upon the left of the slots. The days upon the right are arranged for an ordinary year, while upon the leftthey are arranged for leap-years. Parallel guide-strips B B are secured to the rear face of the card above and below the slots, and sliding between these strips is a card C, having the days of the week printed upon its front face in vertical order and in seven distinct columns, each succeeding column to the sible combination of days in proper order is attained. The days are arranged in as many groups as there are slots, and only one week at a time shows through each slot. The card is adapted to be slid horizontally back and forth, and for this purpose the strips are rabbeted, as shown at h, thus permitting the card to slide, but preventing its displacement.
D and D indicate tables attached to the card to illustrate the manner of using the same, and E indicates a seriesof scheduleleaves attached to the card and used in connection therewith, said leaves having tables marked thereon for computing dates before and after Christ, and according to the old and new styles, respectively, each leaf having a separate table.
As before stated, the calendar is set for 1892; but we will suppose, for the sake of illustration, that itis desired to find what day July 4, 1892, will come on. By referring to table D we are instructed to divide all centuriesafter fopr hundred by four, and by dividing eighteen by four we have two for a remainder. This indicates that we must look in column two of the centuries upon schedule-leaf E, and then by tracing the horizontal column across until we find 92 we see that 1892 came in on Friday. The card C is then adjusted so as to bring Friday opposite January 1. From schedule E it will be seen that 92 has a dot in front of it, thus .92, which indicatesthatit is a leap-year, and for leap-years we are referred to the calendar at the left. Now coming down to the month of July we lind that the fourth day will come on Monday.
Further details of the tables are not necessary, as it can be seen that any year can be quickly and easily found and any day thereof determined.
We do not wish to limit ourselves to the precise construction shown, but may vary the same somewhat without departing from the broad principles of our invention.
Having thus described our invention, what we claim is- 1. In a calendar of the class described, the combination of a card having a central slot or slots and the days of the year marked upon opposite sides of said slot or slots and a card adapted to slide upon the back of the main card, said sliding card having the days of the Week marked thereon in diferent co1- umns, al1 substantially as shown and described.
2. In a. calendar of the class described, the combination of a main card having a. central slot or slots, the days of the ordinary year arranged upon one side of the slot or slots and the days of the leap-year arranged upon the 1o opposite side of the slot or slots and in reverse order, the strips upon the rear face of the main card, and the sliding card havin g the days of the Week arranged "thereon in diiering columns, all substantially as shown and described.
