PERPETUAL CALENDAR.

Specification of Letters Patent.

Patented May .28, 1907.

Application nea May 4, 1906. serial No. 315,219.

The main object of this invention is to' provide an improved frame for perpetual calendars, suitable for being hung upon the wall and of suitable structure to provide for the convenient shifting of the cards bearingthe dierent dates and names of the days and months. This object is accomplished by the device shown in the accompanying drawings, in which:

Figure 1 is a front elevation of the calendar frame having date cards therein.' Fig. 2 is a vertical section taken on the line 2--2 of Fig. 1, but showing the ring 19. Fig. 3 is a horizontal section on the line 3-3 of Figs. 1 and 2.

The mainpart of the frame is formed of the members 1, 2, 3, and 4. The members 1 and 3 have secured thereto the rabbeted members 5 which, together withl the main frame, form a seat in which the card-retaining frame is slidable. The member 4 is cut away at 6 as shown in Fig. 3, to permit said card-retaining frame to slide outwardly from the main frame-along the rabbeted members 5. The lcard-retaining.frame consists of a back piece 7 having secured thereto the rabbeted members 8, 9, 10, 11, and 12 for slidablyretaining the- cards 13, 14, Aand 15. The back piece`7 is cut away at 16. to permit of readily` gripping thecards to pulll the same out of their seats in the inn'er sliding frame. The cards are apertured at 17 to aid the operator in readily gripping and removing t e upper or front cards from the others. The members 1, 2 and 3 are grooved to 'receive a pane of glass 18 which covers the cards and the front of the sliding frame; Said glass may be readily slid into the frame from the `open end at the member 4.

In operation, the inner frame will Abe drawn part way out of the1 mainframe when it is desired to change thecards. The operator can readily do this by grasping one of the'members 1,1 or`12 between two fingers and drawing the same outward to bring the apertures 17 free from the member 4 of the' mainframe. The front card of any or each set may then be readily withdrawn and transferred to the rear of the set, as required in order to show the proper date.

What I claim as my invention and desired to secure by Letters Patent is;

1. A main frame in the form of a picture frame, having one of its side members reduced at the rear, said frame being provided at the top and bottom with a rabbeted cross piece7 an auxiliary frame slidable between said cross pieces and adapted to be removed from the reduced side, said auxiliary frame being provided with rabbeted cross pieces adapted to slidingly retain a card therein and being open to ex ose said card toward the front, said main Irame having va groove forward of and around vsaid sliding frame and opening toward said reduced side, and a pane of glass slidable into said groove from said reduced side.

' 2. The combination of a main frame in the form of a rectangular picture frame having one of the upright members reduced in thickness by cutting the same away at its rear, a pair of rabbeted cross pieces extending across the rear of the upper .and lower members of the frame, an auxiliaryframe slidable between said rabbeted members, being open toward the front and adapted to slidably retain a card therein, said auxiliary frame being open toward said reduced side to permit the removal of said card.

r 3. The combinationof a main frame in the form of a picture frame having` one side rev .l

9 l rear, anV auxiliary frame slidably secured to L duced in thickness by being cutaway at `its the back of said main frame and adapted tov be removed therefrom at said reduced side,

said auxiliary iframe consistingk of a back'.

piece having rabbeted cross pieces `on its face or slidably retaining cards thereon,` Vsaid auxiliaryv frame being open -at the 'red'ucedV Vside of the mainframe to permit the removal 1 i of the cards, 'and having its back piece cut away at saidopen side, and cards overlapping the cut-away part ofsaid back piece.

Signed at Chicago this 2nd day of May 1906.
