PERPETUAL CALENDAR.

SPECIFICATION forming part of Letters Patent No. 508,454, dated November 14, 1893. Application filed April 3, 1893- Serial ITO-468,857. (No model.)

To aZZ whom, it may concern:

Be it known that I, HoWAnD L. WEED, a citizen of the United States, residing at Spokane, in the county of Spokane and State of Washington, have invented certain new and useful Improvements in Perpetual Calendars and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention-relates to improvements in perpetual calendars. I

Briefly described, my improved calendar is of the ordinary hanger variety and consists of a hanger-card adapted to be hung against a wall, or, in a similar position, said card having on its face a stationary line of lettering indicating the days of the week, a plurality of slots or openings through which the months and years are visible, and at each side edge a curved or rounded guide bearing for the movable date strip, ro'table disks pivoted on the rear of the card and having on their faces, respectively, letters indicative of the several months of ayear, a series of numerals indicating the first three figures of a numoer of years and a series of numerals from O to 9 indicative of the year terminals which latter disk is positioned and arranged to rotate so as tobring'the numerals thereon in line with the numerals on the other numeraldisk, an endlessdate strip loosely mounted upon and surrounding the lower part of said card and adapted to slide across the face and around the side edges thereof and having on its face a series of thirteen date-columns with dates so positioned thereon that as said strip is turned any seven columns will present on the face 'o'f'lthecard, and in proper position relatively to the'stationary line of week days :thereon, thirty-one day dates, and a supplerepresents a front elevation of a calendar constructed according to my invention. K Fig. 2

represents a rear elevation thereof. Fig. 3

represents a plan View of the date-strip in its entire length with the edges disconnected. Fig. 4 represents a similar plan view of the supplemental date-covering strip. Fig. 5 represents aplan view of the rotatable monthand-year-indicating disks. Fig.6 represents a top edge view of the complete calendar.

The object of my invention is to produce a calendar of the ordinary hanger or wall variety in customary use in which the days of the week are immovably indicated by a line of letters commencing with Sunday and terininating with Saturday and in which the dates of the respective days of the Week for the month appear in column form below said days but, in lieu of attaching to the hanger card a series of tabs with numerals for each month thereon, enveloping that portion of the card below the line of day names with an endless strip of suitable flexible material having on its face a series of thirteen columns containing date-numerals so positioned that, as said strip is turned upon the card to bring the numeral l under the day of the week'on whichthe first day of the month falls, every seven date columns so exposed at the face of the card will indicate thirty-one date numerals, and in loosely mounting upon the lower portion of said date-strip a supplemental endless strip which envelope and is adapt ed to slide over the lower portion of the face of said date-strip and around the side edges of the hanger-card,- said supplementary endless strip having a series of unnumbered columns or squares on its face registering with, but inequal in number to, the date-squares to the date-strip thereby forming shoulders by which, as said strips are turned, the unneces-'- sary date-terminals may be covered. a 1 represents the hanger-card which is provided with slots or openings 2, 3, through which the names of the months and the yeardates, respectively, may be viewed tt represents a disk rotatably journaled atitherear of said card 1 and having around its ,circum. ference the month names which register with the slot 2. 5 represents a smaller rotatable disk similarly pivoted to the card and hav- 2 ing thereon a series of-numerals representing the first three numbers of a series of years" 6 represents.

which register with the slot 3.

a smaller disk 'rotatably pivoted on the said I card and having around its circumferencea series of numerals from 0 to 9 which, as said disk 6 is rotated are, as shown in Fig. 1, brought into line with the numerals on the disk 5. By this arrangement my calendar is adapted for use for a great many years the number depending upon the size of the disk 5. 7 represents a permanent and stationary line of lettering on said card indicating the days of a week. 8, 9, represent curved or rounded guide-bearings for the date-stri p to bepresentlydescribed. Theseguide-bearings may be formed in a variety of ways, such, for instance, as by rearwardly-curving the side edges of the card and either, or not, placing therein a suitable core, 10, or by attaching to the edges of said card tubular or cylindrical strips of suitable material. By the use of these rounded bearings the date-strip will be smoothly guided around and have frictionless bearing upon the hanger card.

11 represents the date-strip which is formed with a series of thirteen date-columns 12 within which is arranged a series of datenumerals so disposed that as said date-strip is turned on the hanger-card to bring a line of seven of said date-columns under the names of the days of the week each series of said seven columns will present not less than thirty-one day-dates.

The object of my invention being to produce a calendar which shall be perpetual in its character and yet have the general appearance of and be used in lieu of the ordinary wall or hanging calendars whose life does not extend beyond one year, and as the first day of the several months falls upon variable days of the week it becomes necessary to duplicate a portion of the numerals on my endless and slidable date-strip. In order to provide for the proper disposition of daydates under all circumstances and with the least possible employment of dates the said dates are thus arranged on the (late-strip, viz :In the top horizontal line six blank squares are left at the left hand, the numerals on this line running from 1 to 7 inclusive; on the second line from the top the numerals run from 2 to 14; on the third line from 9 to 21; on the fourth line from 16 to 28; on the" fifth line from 23 to'3l with four blank spaces on the right hand and on the sixth horizontal linefrom 30 to 31 inclusive. Inasmuch as, in turning my date-strip around the side edges and across the face of the date card so as to bring the date numeral 1 under the name of the dayon which the particular month commences it will sometimes happen that more date-terminals are exposed to view than there are days in the month, or a duplication of the day-dates are visible, it is necessary to provide some means whereby such redundant dates may be covered. This I accomplish in a very simple yet an entirely effective manner by the employment of an endless strip of suitable pliable material 13 which surrounds nd slides across the face of the date-strip 11. This supplemental date-covering strip 13 has on its face a series of blank columns or squares which register with the adjacent columns and squares on the date-strip 11 but, in lieu of continuing the operative horizontal lines of squares, 14, 15, the full length of the strip the upper line 14, consisting of but four squares terminates in an inner shoulder 16, while the horizontal line of squares 15, next below the line 14 consists of but eleven squares and terminates in an inner shoulder17. Itwill thus be seen that these shoulders 16, 17 are separated from each other the distance of one square apart vertically and seven squares apart, horizontally. These two lines 14, 15 are in the same horizontal plane as, and, as said strip 13 is turned, travel along and across the two lower date-lines of the date-strip. It will be readily apparent that when the date-strip has been turned to bring the appropriate numerals under and in proper registry with'the day names by turning the supplemental strip 13 the stepped-lines 14, 15, t can be readily brought over the redundant date-numerals on either or both of the lower lines on the datestrip.

18 represents knobs, buttons or equivalent devices attached in any suitable-manner to the rear of said strips 11, 13, to facilitate the movement thereof.

What I claim, and desire'to secure by Letters Patent, is
