INVENTOR. ROBERT MERLIN BRYANT A T TORNE Y Patented Apr. :17 l951 I I f UNITED, STATES PATENT OFFICE Robert Merlin Bryant, Baltimore, Md. Application March 29, 1948, Serial No. 17,729

4 Claims. (01. 4o 115) This invention relates to calendars and more chanicallyoperated. In a particular form of mechanical. calendar, the numerals indicating the days of the month are arranged consecutively on membersthat are rotatable separately to showany number from 1 to 31 inclusive for designating the date. These numbers appear'inside a frame located suitably for observation Adjacent these numerals, is another member with the names of the months positioned thereon, subject on rotation to appear in another frame. Another member and frame is similarly used to designate the names of the days of the week. These members are manually operated, to show the month, day of the week and date in a single line. While this arrangement is convenient and avoids the need for the pad of 12 leaves of months commonly employed, which are relatively wasteful, it requires a relatively cumbersome mechanism, is heavy, and is limited to the conventional dating. For instance particularly to those havingdatingrthat is methere is no way of determining from such a cal- I endar the identity of holidays, by any convenient manner. r

In this invention, the calendar is preferably in the form of a flat main sheet of stiff material suitable for hanging on a wall or placing on a desk or other fiat surface. It has various discs in back that may be rotated to present themselves for observation in openings or windowsprovided r in the main sheet, in such positions as to disclose,

a number for the date, a name for the day of the week, and another marking for the month, and the number of daystherein. In addition there is a space that enables the dates on which holidays exist, to present a code sign that canbe readily. recognized as a holiday. Further than that, an arrangement is provided forretaining the'calendar in its monthly period, in a most effective manner, but readily changeable to suit a change to a new month display.

There is in addition to the above advantages, a color code which is set out for each individual month and is usually applied to a handle which is used to'turn the calendar to the next month. This same set of colors is-set out above the -slot on whichthe days of the week appears. In use the color of the month is noted and the day of the week will be found below the same color set out above its proper day. 1

In all, however the operation of the deviceis very simple and the cost of construction relatively economical. It also is very readable and attractive. I

For a better understanding of the invention reference is made to the I appended drawings which disclose a particular form of the invention byway of example; The description of this form if he inventions are. 1 illei a 'sp '2 fi cation, while the scope of the invention is emphasized in the claims. 7

Referring to the drawings:

Similar reference characters relate to the same parts throughout the drawings. I

In the structure shownin the drawings, a cas ing In of two sheets I2 and 92 of cardboard, plasline tic or other material suitable for the purpose,

near the top and about its vertical axis. This slot, I3 serves as a window for observing the names of the months, I4 (one at a time) as well as the number of days in .the specific month as the disc I5 on which they are printed is rotated. Another slot I6 is arcuately cut out of the front sheet I2, and situated below the slot I3 and is preferably longer, to allow the indication of the seven days, I l, of the week in the window formed by .it. These days, ll, of the week are printed on the periphery of a disc I8, located between the front and back sheets of the casing I0. Another smaller window 20 is cut out of the front sheet l2 and located under the previously mentioned window I6. This window 20 discloses the date numerals, 50, which are also printed on the disc I8 below days, IT. A vertical window I9 is cut out of the front sheet I2 and is made relatively long in order to disclose the marks 2| of a special code used to identify holidays,'or other spe-' ci al occasions during the year. These marks 2| arepreferably colored and printed on the disc I5,

as part of the months specifically needing them.-

in the sheets I2 and 92 ofthecasing I0 serve as a:

I Sunday, July 4th is a holiday.

- pears in its tab 35.

bearing for a stud 23 to project through. This v stud 23 has a knob 24 which presses against the front sheet I2 and is used for manipulating the stud 23 and disc [8. The stud 23 is provided with a square shoulder 45 and washers- 2.5 that. engage with the square hole 58 of the disc or member I8, so that the rotation of the stud 23 will also rotate; the disc [8. A printed circular row 26 is marked with small colored circles, black 27, brown 28, white 29, red 36, yellow 3|, green 32, and. blue. 33. in the areas partitioned off by the lines 34 as indicated. These areas are stationaryand are directly above and register with the spaces in which the days, [7, of the week appear when set in their various predetermined arrangements,

behind thewindows. The disc I has a superimposed colored circle tab 35 for each month. The colors of these tabs 35 have certain relations to the circles in the circular row 26, which will be explained later on. Holes 36 in the sheets of the casing l0 serve to facilitatethe hanging of the calendar on a nail on a wall and at the same time align with a hole in the month disc 15. The nail in passing through the holes holds the month disc locked in one position. The month therefore selected at the time, will be kept locked in position during the month of its use. A slot 40 in the channel 4| of the stand 42 may be used for same purpose, when the calendar is supported in the channel 4! of a stand 42. vided on the front sheet [2 to enable announcements 43 to be shown.

The operation of the calendar is as follows: The user first sets the selected month I4 by moving the disc 15 to the window 13-. This brings the colored tab 35 into the users view. This color tab 35 is compared with the colors of the circles 2'!v et seq., over the days ll, after the date numeral 56 is shown in its window 29. As an example, assuming that July is the month selected, and the color it has is black. Then the knob 24 is turned until the date 4 is disclosed at the-window 29. This turns the days I! and reregisters them under the colored circles in the circular row 26, which happens to align the day Sunday under the black circle. The mark'2l will show through hole 22, showing that If we turn the month February into place, the color red ap- Then if the knob 24 is turned until 22 comes into view, the days I'l- Will rotate until Sunday is under the red circle of the circular row 26. When this is done, it will be noticed that another mark 21 has appeared on the calendar, in the hole 22 and window [9. This mark 21 indicates that this date is also a holiday. Similarly the calendar is changed for other months, and numeral dates. The setting of these two items also enables the reader to determine the day of the week automatically.

The colors of the tabs 35 are arbitrarily made as follows: January, black; February, red; March, yellow; April, black; May, white; June, green; July, black; August, red; September, blue; October, brown; November, yellow and December, blue. 7

While but one general form of the invention is shown in the drawings and described in the specifications, it is not desired to limit this application for patent to this particular form or in any other way otherwise than limited by the scope of the claims, as it is appreciated that other forms of construction could be made that would use the'same principles and come within the scope of the appended claims.-
