PERPETUAL CALENDAR- Specification of Letters Patent.
Patented Feb. 6, 1906.
Application filed March 1,1905. Serial No. 247,931.
To a, whom it may concern.-
Be it known that I, OIIARLEs P. HIDDEN, oi the city of Baltimore and State of Maryland, have invented certain Improvements in Perpetual Calendars, of which the following is a specification.
This invention relates to certain improvements in Calendars which admit of the days of the week being changed with respect to the days of the month, as will hereinafter fully appear.
In the further description of the said improved calendar, which follows, reference is made to the accompanying drawings, forming a part hereof,'and in which Figure 1 is a front view of the improved calendar, and Fig. 2 a vertical section of the same.
Referring now to the drawings, 1 is the foundation or back of the calendar, which may be formed of stifl cardboard. carrying certain strips, hereinafter described, upon which are printed. the days of the month, beginning with the numeral 1 and ending with the numerals 31. The numbers representing the days of the month are arranged in horizontal lines, each line except the last and lower one having seven numbers which represent the days of a week. The said numbers are not printed directly on the cardboard back, but instead on strips of cardboard 2, which are pasted to the back, and in order that the spaces between the horizontal rows of figures may be adapted for the reception and retention of cards or slips of paper 3, bearing memoranda of various kinds, the strips 2 except the top one are pasted only at their lower edges to the back, as shown at 4 in Fig. 2, the upper edges being loose, thus providing narrow spaces or pockets 5 in which the said cards or slips oi paper are or may be inserted.
Over the upper and the lower ends of the back 1 are placed the endless flexible bands 7 and 8, upon which are printed the names of the days of the week or contractions thereof, each band having two sets, one set following the other. These bands are adapted to be slid. around the back 1, the upper band to bring the name of the proper day of the week to the first day of the ensuing month and the latter so as to make the present month terminate on the correct day oi the week. The obj ect .in providing the calendar with two bands 7 and 8 is to admit of the noting of engagements for parts of two months, and it is to this end that the lower band is made to represent the present month and the upper band the ensuing month, as before stated. To prevent complication, however, the phrases Ensuing month and Present month are printed over the upper and the lower band, respectively. The upper endless flexible band 7 is secured. against displacement by confinement between the top cardboard strip 2 and a similar strip 9, and the lower flexible band is similarly secured. by. being placed between the cardboard strips 10 and 11, and. it is upon the strips 9 and 10 that the abovcmentioned phrases are respectively printed. To identify the present month, the strip 10 is adapted to hold twelve separate cards, each one of which has printed thereon the name of a month. The stack of the cards is denoted in Fig. 2 by 12.
If desired, the memorandum cards or slips for the present month and the ending month may be of different colors; but as engage ments are usually made several days in advance little complication will be met with in arranging the cards should they be white or all of a uniform color.
I claim as my invention 1. In a perpetual calendar, the combination of a back carrying a series of strips which are inscribed with the days of the month and secured at the lower edge only to the back, and extending entirely across the back from side to side thereby producing continuous pockets for memorandum-eards, and an endcss band on which is inscribed the days of the week, and the said band being placed loosely over and around the back and. adapted to be moved laterally in either direction independently of the back to adjust the days of the week to the days of the month, substanti ally as specified.
2. In a perpetual calendar, the back there: of having the days of the month fixed thereon .in horizontal rows, and arranged to be read from left to right, combined with two inthe other similar band, being situated below dependent horizontally-placed and movable l the said rows of figures, substantially as and endless bands inscribed with the days of the for the purpose specified.
