It is proposed to movably mount the The perpetual calendar, in accordance with year behind said support sheet so that eachjyear that form of the invention disclosed in Figs. 1 to ‘ it may be turned to a new position and display the number of the year through the opening in 10 3 inclusive, includes a support sheet In having an‘opening II for viewing a year plate I12 which said support sheet.

The year plate small day of the week disc, and a medium month 82 is imprinted with numbers, representing the disc, and a large numeral disc coaxially with each years, which are viewable through the opening other on the front of said support sheet. A star I2 when the year plate is turned to various po tionary indicator is mounted on said support sheet and extends across said discs, and is pro As illustrated on the drawings it is in a posi vided with window openings for displaying one tion in which the year 1945 is displayed. It may notation of each‘of said discs. 7 be‘turned to display subsequent years, as needed. The invention also proposes imprinting the The support plate I ii is provided‘ with alarge top support sheet at areas around the large numeral area I5 which may be imprinted with a picture, disc with sections indicating the months, and sitions. ‘ . ‘ or a puzzle, or other material to make the cal sections indicating the holidays contained in each endar attractive, and decorative. of the months.

They serve to hold the said , For further comprehension of the invention, and of the objects vand advantages thereof, ref erence will be had to the following description and accompanying drawings, and to the ap pended claims in which the various novel features of the invention are more particularly set forth. In the accompanying'drawings forming a ma terial part of this disclosure: 40 _ of the week; Monday, Tuesday, etc. The medium Fig. 1 is an elevational View of a perpetual cal monthv disc I8 is divided into 12 areas which are endar constructed in accordance-with this‘inven tion. ‘ . . l ‘ i ‘ ' Fig. 4 is a front elevational view of a perpetual calendar constructed in accordance with a modi ?ed form of this invention. imprinted ' month,‘ for example, January has ‘31 days, and February has 28 days, and leap years 29 days, etc. 50 The large numeral disc I?! is imprinted with 31 areas numbered from 1 to 31 and representing the ‘ days of the month. ‘ > ‘ year, namely, January, February, etc. These areasare also imprinted with nota tions to indicate ‘the numbers of days in each Fig. 5 is a fragmentary enlarged detailed View of a portion of Fig. 4. with notations representing. the " months of the . Fig. 2 is a perspective. View of the calendar shown in Fig. 1 but drawn on a reduced scale. Fig. 3 is a vertical sectional view taken on the line 3—-3 of Fig. 2.2 discs against free turning. However, each disc can‘be manually turned. The day of the week disc I‘! is divided into seven. peripheral areas imprinted with the days The stationary indicator-His supported on the I ii and extends across said discs I'l,_. l8 and 7 support sheet “ 55. l9, and is provided with window open 2,411,185 3 ings 28 for displaying one notation of each of said discs. At the top, the indicator 21 is sup ported on a block 29 which is attached to the support sheet H] with ‘fastening elements 39. At the bottom, the indicator 2'! is engaged over the I221 pintle pin I3 and is securely held by the head of ' the pintle pin. The support sheet l0 has a top opening 32 by which it may be hung up on a nail, or other support on a wall, or other object. The support sheet It is also imprinted with a circular area 34 about the large numeral disc 19 which is formed with sections 35 imprinted , with the names of the months. Adjacent these sections 35 there are radiating sections 36 which are imprinted with the holidays contained in each I 4 moved back and out from the serrations 2! in the disc, and it may be turned. If it is desired to free the discs l1, l8 and I9 simultaneously so that they may be turned, as desired, without interference, the ?anges 4| of a slide plate 40 are manually gripped and moved, upwards. Thus the slide plate 40 is raised, lift ing all of the tooth-like projections 51 out from the serrations 2!. This is of particular advan tage when the calendar was not used for some time and all of the discs are in wrong positions, and must be reset. ' ' . It is to be understood that this device may be used not only in connection with calendars but any other data may be inscribed on the various \discs such as" information about geographical lo month. For example, the month of March is cations, mathematical calculations, etc. imprinted as having St. Patrick’s day on March While I have illustrated and described the pre 17. ferred embodiments of my invention, it is to be The calendar is used by rotating the small understood that I do not limit myself to the pre day of the week disc l1 and the large numeral 20 cise constructions herein disclosed and the right disc 19 each day so as to display the correct day. is reserved to all changes and modi?cations com The medium disc I8 is turned each month so as ing within the scope of the invention as, defined to display the proper month. Theyear plate i2 in the appended claims. is turned each year. ' In Figs. 4 to 8 inclusive, a modi?ed form of the invention has been disclosed which is very similar to the prior form distinguishing merely in the fact that means havelbeen provided for hold ing the discs ll, l8 and 19 from turning, and this means is adjustable to free the discs so that they may be turned individually, or as a unit. This means includes a slide plate 4-9 engaged across the back of the indicator 21 and having edge portions 4! engaged around the edges of the indicator 2?, and engaging cutouts 62 formed in - the edge of the indicator 2'! by which the slide plate 40 is limited to move a short distance up wards and downwards. Leaf springs-.43 are mounted upon the bottom of the support block as and engage the top edge of the slide plate at normally urging it into its bottom position. The slide plate 40 has window openings 44 which are alignedv with the window openings‘ 28. of the indicator 2'! so as not to in terfere with viewing the several discs through the window openings. A plunger 46 is provided with each of the discs l1, l8 and I9 and each is slidably' mounted through a tubular’ socket ill ?xedly mounted on the ‘back of the slide plate til. The stationary indicator 2'! is formed‘ with small ventical slots 48 through which the plungers 46 pass.‘ These plungers 46 are square, in transverse cross sec ' tion, and the sockets 41 are similarly shaped, limiting the plungers to slide inwards and out~ wards, and restraining them from turning. Each plunger 45' is provided with a knob t9 by which the plunger may be pressed inwards. Each Having thus describedmy invention, what I claim as new, and desire to secure by United States Letters Patent is: l 1::A perpetual calendar, comprising a'support sheet having an opening for viewing a yearjplate, a serrated small day of the week disc superim posed on a serrated medium month disc superim- ' posedon a serrated large numeral disc coaxially turnably mounted on said support sheet, afsta tionary indicator supported onv'said support sheet and extending across'said discs and having‘win dow openings for displaying one notation of each of ‘said discs, a year plate turnably mounted in back of said support sheet, and means for holding said discs from turning and adjustably to free‘ the discs individually, or as a unit, including a slide plate slidably mountedon said indicator and having window openings alignedwith the win dow openings of said indicator, resilient means for urging said slide plate downwards, a plunger for each of said discs mounted on said/slide plate through non-circular sockets, saidplungers being non-circular and complementary to said sockets, and tooth-like projections on the ends of" said plungers engaging theserrations on‘ the discs. 7 '7 2.

These tooth-like projections ?xedly'hold the discsfrom being turned. The operation of this form of the invention is substantially identical to the prior form, dis tinguishing merely in the fact that, it is neces~ sary to free the discs ll, [8 and I9 before they may be turned. Each disc may be freed by press ing inwards the plunger d6 associated with the disc.
