Application filed November 10,1921. Serial No. 514,366.

To all whom it may concern:

Be it known that I, PAUL O. Laurie, a citizen ot 'the United States, residing at Easton, in the county ot Northampton and State ot Pennsylvania, have invented a new and useful Calendar, of which the following is a specification.

This invention relates to calendars, the primary object of the invention being to provide a calendar having comparatively few parts, wherein one section may be moved with respect to the remaining. sections to indicate predetermined days and months oi a year.

Another object of the invention is to provide a calendar which may be referred to, to ascertain dates of preceding years and months. Y

With the Jforegoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing trom the spirit of the invention.

Referring to the drawings:

Figure 1 is a plan view of a calendar constructed in accordance with the present invention.

Figure 2 is a. plan view of the movable member disposed to the rear of the main member of the calendar.

Figure 3 is a plan view of the movable section associated with the movable member.

Figure et is a rear `elevational view of the calendar and Figure 5 is a sectional view taken on line 5-5 of Figure 4.

Dreferring to the drawings in detail, the calendar embodies a main member indicated at 5 and which is constructed of card-board, or similar sheet material, the same being provided with a cut out portion 6 disposed substantially centrally thereof, and through which out out portion, the movable member indicated at 7, and which is disposed behind the member 5, may be viewed.

Elongated openings 8 are formed in the member 7, which openings accommodate the rivets indicated at 9, and permit of sliding movement et the movable member 7 with respect to the member 5, so that the number which are formed on the movable member 7, may be moved into alignment with various indicating characters on the member 5, for purposes to be hereinafter more fully described.

Disposed between the members 5 and 7, is a movable member indicated at 10, which is also provided with openings registering with the elongated openings 11 or' the member 7, which openings accommodate the rivets 12 to permit of movement of the member longitudinally of the members 5 and 7 to cover up certain indicating characters on the member 7. A column indicated at 13 is formed at the left of the cut out portion 6, in which column are arranged indicating characters indicating the days of the week, while at the right of the cnt out portion 6, are a plurality of columns 111 in which are arranged the months of the years, the years being indicated above the column 14 as clearly shown by Figure 1 of the drawings.

ln the use of the calendar, the calendar is shown in Figure 1 ot the drawings indicating the days ot the month 'for J une 1921, February, March and November of v1922, and August of 1928, that is to say the member 7 has been moved to bring the numeral 1, indicating the first day of the month opposite June in the right-hand column, which is disposed under 1921 of the column above.

It it should be desirable to lind the day on which the 22 of February 1922, falls, the member 7 is moved to bring the numeral 1 opposite February in the 1922 column. lVith the member 7 in this position, the eye follows the line of numerals to the lefthand column of the member 5, and it will be seen that February 22, 1922, falls on lVednesday.

It might be further stated that the slidable member 10 is moved to cover the last numbers of the movable member 7, so that only the exact numbers of days of a month will be visible through the cut out portion 6.

Having thus described the invention, what is claimed as new is A calendar including a body portion having a central'cut out portion, the portion of the body adjacent to the side edges of the cut out portion being ruled to provide columns for the reception ot indicating characters indicating the days of the week and the months et' the year, a movable inem` Cil ber having numbers and having elongated openings formed therein, rivets Carried by the body portion and disposed in the elongated openings to slidably connect the body portion and movable member, and a movable member having elongated openings movable between the body portion and first mentioned movable member, rivets carried by the first mentioned movable member and disposed lin the elongated openings of the last mentioned movable member, and the last mentioned movable member having a shoulder formed on one of the side edges thereof, and said shoulder adapted to be moved to align with the numbers on the first mentioned movable member.

ln testimony that I Claim the foregoing as my own. :I 'have hereto affixed my signature.
