- CALENDAR.

Application filed June 13, 1925. Serial No, 36,769.

The present invention relates to a perpetual calendar.

A calendar for use in an office or home is usually displayed upon a wall in a prominent position, and it is, therefore, desirable to have the calendar as attractive as possible. here a calendar of an ordinary type is employed wherein a pad of superimposed sheets, each of which contains the days of a month, the entire calendar becomes obsolete at the end of a year, since the dates of one year do not fall on the same week days as those of the next succeeding year.

An object of the presentinvention is to make a calendar having month, day, and

date indicia thereon, which may be adjusted to indicate any required combination of month, day, and date.

Another object is to make a perpetual calendar which may be used over an indefinite number of years during the life of said calendar. I

In order to attain these objects, there is provided in accordance with one feature of the invention, a base plate having a pair of apertures therein, and a pair of disks pivoted to the rear of said plate, one of said disks bearing the months of the year in succession positioned around the outer edge to displayone of said months tl'irough one of said apertures, and the other bearing the days of the week in a similar manner with respect to the other of said openings.

Aitixed to the base plate below the apertures therein, a bracket is atiixed carrying a supporting arm pivotally mounted thereon. A pair of loops removably connected to said arm support thirty-one cards, each of which is inscribed with a large numeral, the numerals running from one to thirty-one in numerical succession. A clasp is connected to the base plate to engage an aperture in the supporting arm to normally hold it in parallelism with the face of the base plate.

In the accompanying drawings: Figure 1, is a View in front elevation of a calendar made in accordance with the present invention.

Figure 2, is a thereof.

Figure 3, is a view in front elevation of a supporting arm having a plurality of dated cards mounted thereon, showing a modified form of card supporting loop.

view in side elevation Figure 4, is a view in side elevation of the structureshown in Figure 3.

Figure 5, 1s a detail of a loop employed in the structure illustrated in Figure 1; and

Figure 6, is a similar view of a loop employed in the structure shown in Figures 3 and at. s

Referring to the drawings in detail, a plate 1, which may be of heavy cardboard, has a pair of hooks 2 integrally connected to the upper portion thereof, upon which a secondary plate 3, also of cardboard, is af- .tixed by inserting the hooks 2 through slots i therein. A disk 5, which may be of celluloid, or a good grade of cardboard such as bristol board, is pivotally mounted to the rear of sheet 3 by means of an eyelet 20. Printed about the rim of disk 5 are the twelve months of the year in succession, the month Jan appearing in the illustration through an aperture 6 in sheet 3. Similarly pivotally mounted to the rear of sheet 3 is a second disk 7 upon which the days of the week are printed successively in a similar manner to that in which the months of the year are printed on disk 5 and are positioned to appear in rotation through an aperture 8 in plate 3.

Aiiixed to plate 1 by suitable means such as rivets, not shown, is a bracket 9 to which an arm 10 is pivotally connected. The opposite end of arm 10 is provided with an aperture 11 which is engaged by a spring clip 12 also affixed to the base plate 1 in a suitable manner to hold the arm 10 in parallel spaced relation from the base plate 1. A pair of loops 21, which may be'strips of metal such as brass, are aflixed to the arm 10 by means of rivets 13. Before affixing the loops to the arm a plurality of date bearing cards l i are placed in position on'the loops, the date bearing cards being provided with slots, not shown, similar to slots at in plate 3. The loops are of elongated elliptical shape, and are designed so that either half of the loop may contain the entire thirty-one cards in depending position therefrom, as shown in Figures 1 and 4.

A modified form of loop is shown in Figures 3, i, and 6, and is intended to be removable for the replacing of worn or damaged date cards. In this structure a loop 15 is provided with a pair of depending end portions 16 which are inserted beneath a ing disk is set to indicate the month desired.

The disk bearing the days of the week is similarly positioned, and the date bearing arm is released from clip 12 and swung to V a position at right angles with the base plate 1. The date bearing cards are then moved upwardly over the top or arm 10 to the front of said arm to display the required date. The arm 10 is then swung back to the posi- .tion illustrated in the drawings and secured in position by means of the spring clip 12. For each successive day, one date card is moved to the rear of arm 10, and the disk bearing the days of the week is rotated one position. At the beginning of a new month the month bearing disk is rotated one posi tion in addition to the other operations and the entire set of cards are moved to the front of the arm 10 to display the numeral 1.

' While a separate plate 3 is here illustrated as supporting the disks 5 and 7, the disks may be secured to plate 1 to accomplish the same result.

What we claim is:

l. A support for calendar date cards, comprising a bracket mountable upon a supporting plate, an arm pivoted to swing in a horizontal plane upon said bracket, a clasp positioned to engage an end of said arm to hold it in parallel spaced relation with respect to a supporting plate, a pair of loops mounted on said arm, and a plurality of date cards threadedly mounted on said loops and movable thereon about said arm to position any one of said cards in a display position.

2. A calendar of the character described, comprising a plate, a disk hearing dateindicating indicia thereon pivotally mounted on said plate to display one of said date in dicating indicia at a time, a bracket mounted on the plate, an arm pivotally mounted on said bracket, a clasp to normally hold the arm in parallel spaced relation with respect to said plate, and a plurality of numeral bearing cards mounted to depend from said arm and movable about the arm as an aXis to position any one of said cards in a display position.

3. A support for calendar date cards, comprising an arm hingedly mounted to swing in a horizontal plane, a pair of loops removably connected to said arm, and a plurality of date cards threadedly mounted on said loops and swingable about said arm to expose any one of said cards.

In testimony whereof we atlix our signatures.
