CALENDAR.

SPECIFICATION forming part of Letters Patent No. 439,810, dated November 4, 1890.

Application filed .Tune 17, 1890. Serial No. 355,727. (No model.)

To all whom, t may concern:

Be it known that I, J AMESCASSEDAY, a citizen of the United States, and a resident of New York city, New York, have invented 'an I-mproved Calendar, of which the following is a specification.

The object of my invention is to provide a perpetual calendar which shall be strong and not liable to wear out or get out of order, and which may be conveniently constructed in fancy woods or other like durable material.

In the accompanying drawings, Figure 1 is a iront view of my improved calendar. Fig. 2 1s a vertical sectionon the line 1 2, Fig. 1. Fig. 3 1s a rear View of the calendar with the back plate removed and a part in section. Fig. 4 1s a perspective view o'f a device or devices .for operating the movable plates or slats Cl'rrylng the names of the months, and Fig. 5 1s a view of a modification.

The casing A of the calendar may be constr ucted in any suitable design and of any suitable material. In the drawings I have shown it as in the form of a rectangular boX constructed of wood or some similar material. On the front plate are formed or impressed or otherwise applied the series of iigures a for the days of the month. There are twenty f eight of these figures arranged in seven columns, and in addition to these stationary or. liXed figures there are three movable iigures 29, 30, and 31, held in place by l" Fig. 1, as the letter-block S, for instance, is

springs s to show through an opening or openings s in the front plate of the case. The movable plates ct', carrying these additional figures, are provided with suitable knobs or handles 0,2 projecting through the case at the back, so that they can be conveniently grasped for manipulation. By taking hold of one of these knobs or handles its plate a can be moved, as indicated by the arrow in Fig. 2, backward and downward, so as to withdraw the figure from the opening s until it disappears out of sight, a recess r being formed in the casing in the present instance for the reception of the projecting part of the plate which bears the figure on its face. In this i way any or all of the numbers 29, 30, and 31 may be caused to disappear or show, according to the number of days in the month for which the calendar is set.

Over the columns of figures representing the days of the month are provided seven movable blocks d, carrying the initials or other symbols for the days of the week. These movable blocks are adjustable in an endless guideway D to change their relation to the columns of gures Vin such a way that any one of the blocks for any one of the .days of the week may be brought. to a position over the first day of the month, and the blocks for the succeeding days of the week follow accordingly. Thus if the S, indicating Saturday, had for one month been arranged over the first day of the month, and it was desired to change the arrangement to bring the M for Monday over the first day of the month, the S in question would 'be moved around in the guideway, as indicated by the arrow in Fig. 1, until it should be brought to the opposite end of the line of blocks from which it started. The next S would then be carried around in the same way, and the line of blocks would then be arranged with the M for Monday over the first day of t-he month.

To facilitate the adjustment of the blocks I provide a device in the form of a lever F, pivoted to the casing to move the line of blocks along over the column of tigures for the months as each letter-block is brought around in the guideway. Thus, as shown in brought around in the upper part of the guideway, it strikes the upper part of the lever F, and the latter, swinging on its pivot, strikes with its lower end the line of blocks, so that this line of blocks is moved over to allow the block with the letter S for Sunday to come into position at the end of the line.

Instead of arranging the iigures for the days of the month in vertical columns, as illustrated in Fig. 1, it will be readily understood that they may be arranged horizontally, as shown in the modification, Fig. 5 but in that case the movable blocks with the letters indicating the days of the week will be arranged in a vertical instead of a horizontal line. The names of the months are carried by an endless series of slats or plates H, and there is at any suitable point in the front of the casing (within the space left by the endless guideway, for instance, Fig. l) a slot or opening O, of a size-to allow one month-name to show at a time. The slats H may be united in endless series by any suitable means. For convenience'l have shown them as carried by the endless tapes or bands h, and the series of slats pass around a supporting guide-bar L fixed by any'suitable means in the casing. In this instance the guide-bar is shown as carried by fixed side plates or bars I within the box in the casing.

In order to conveniently move the endless series of slats to bring the names of theY months in regular succession opposite the openingin the front ofthe box or casing, I provide, preferably, the device illustrated more clearly in Figs. 2, 3, and 4:. A movable frame M, consisting of side bars-m and connecting cross-bar m and a connecting handle-bar n outside the casing, is vertically movable to a limited extent inV the casing against the ac,- t-ion of springs p, coiled around the fixed guidebars p', which pass through guide-lugs o on the movable frame M. The cross-bar m of the movable frame M carries one or more spring-pawls L, consisting each of a springplate having its outer end split with one tongue Z bent downward and the other Z upward. The upper tongue l is longer than the downward tongue, so that while the latter engages With the under side of the slat the longer and upper tongue presses on the back of the Slat, Figs. 2 and 4. Thus as the movable frame M is raised by its handle n these spring-pawls will push the series of slats along to an extent determined by the length of the movement of the movable frame M, and this is made about equal to the width of a slat.

To prevent the series of slats from moving backward on the return movement of the frame M, suitable spring-pawls lc (conveniently made of wire) act on the under sides of the ends of one of the slats. These ends are suitably beveled, as shown in the drawings, with reference to the position and action of these retaining-pawls.

I claim as my invention- 1. A perpetual calendar having movable symbols for the days of the week, with a series of numbers for the days of the month, of which twenty-eight are xed and the additional gures needed are movable int-o and out of position.

2. Al perpetual calendar having movable symbols for the days of the week and vtwentyeight ixed numbers for the days of the month arranged in columns, with movable plates carrying additional month-numbers, the casing having an opening or openings for these movable numbers to show through, and springs to retain the plates in their exposed or unexposed position. y

3. A perpetual calendar having columns ot figures for the days of the month, with separate movable blocks carrying symbols for the days of the week,'and an endless guideway in which these several blocks are carried and may be moved to bring any block to the head of the line, substantially as described.

4. A perpetual calendar having columns of figures for the days of the month, with movable blocks carrying the symbols for the days of the week, and al1-endless guideway in which these'several blocks may be moved to change their relation to the figures for the days of the month, and a lever to be acted on by the block brought around in the gnideway to move the line of remaining blocks along, substantia'lly as and for the purpose described.

5. Acalendar having in the casing an opening through which successive month-names may be exhibited, with a series ot' iigures for the days of the month, movable blocks carrying symbols for the days ot' the week, and an y endless guideway'extending around the opening for the names of the months, and in which guideway the said blocks can be moved around to change their relation tothe figures of the month, all substantially as specied.

6. A calendar having a casing with an opening to exhibit the name of the month, an endless series of slats carrying the names of the months, and a reciprocating frame having a handle outside the casing and carrying a pawl or pawls to move the endless series of slats, substantially as specified.

7. A calendar having an opening to exhibit the names of the month, with an endless series of slats carrying the names of the months, and a reciprocating frame with pawls yconsisting of spring-plates with split ends to bear upon the slats, all substantially as and for 4the purpose described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JAMES CASSEDAY.
