6 Claims.
1 This invention relates to a perpetual calendar. More particularly, the invention relates to a photograph mount perpetual calendar which can `be ornamented by a photograph which has some especial meaning to the person utilizing the perpetual calendar.
The present invention is directed toward providing a, new type of perpetual calendar which will not only be of perpetual value as a calendar but which will also be of perpetual value as a photograph mount to the end that the calendar can" be redecorated when desired and kept or" ornamental interest as well as of useful interest.
An object of the present invention is to provide a perpetual calendar which is so constructed that it can stand up on a desk or the like and which has a place for a photograph such as a picture of a mans wife or daughter, the photograph being part of the calendar and ornament- -ing the same.
A further object is to provide a calendar as aforesaid having movable buttons for indicating the day, month and day name, each of the buttons being provided with means for holding it in any position to which it is moved.
For further comprehension of the invention,
and of the objects and advantages thereof, referencel will be had to the following description and accompanying` drawing, and to the appended claims in which the various novel features of the invention are more particularliy set forth.
In the accompanying drawing forming a material part of this disclosure:
Fig. 1 is a front elevational view of a perpetual calendar constructed in accordance with this invention. Y
Fig. 2 is an enlarged partial sectional view of Vthe front member only taken on the line 2-2 of Fig. 1.
Fig, -3 is a rearview of one of the parts of the calendar. I
Fig. 4 is a diametral section through one of the buttons, taken on the line 4-4 of Fig. 5.
f Fig. 5 is a View of one ofthe pins forming part of the button.
Fig. 6' is a perspective view of the calendar partly open, taken from the hinge side thereof.
Fig. 7 is a section on the line 'I--l of Fig, 6.
The calendar I0, according to the present in-` vention, comprises a front member I I and a rear member I2, hinged at I3. The rear member I2 consists of a sheet of board I4, such as cardboard, about the inner face edges of which is a frame I5 vfor retaining a, photograph or picture I6. The rame Vl5 is made of strips of cardboard. Each strip is taped at its outer edge by a tape I1. Similarly the outer edges of the board I4 are taped by a tape I8. When the frame I5 is put on the board I4 the two strips I1 and I 8 space the frame from the board I4 so that the photograph II can be slid into place. A tape I9, covering tapes Il and I8, binds the frame to the board I4, see Fig. '7. The tape I9 has a slit 2l) at the top of the member I2 through which the photograph can be slid. Thus any photograph can be placed in the calendar, making the calendar of interest to the particular person using it. For example, a man can have the calendar on his desk at his place of business and have his childs photograph in it. As the child grows, the photograph can be changed to more recent ones, keeping the calendar up to date as to ornamentation by the photograph.
When the calendar is in use, the members II and I2 are superposed and closely engage each other, the hinge I3, which is made of tape, permitting this. .The calendar is kept in upright position by a leg 2| which is riveted at its top by rivets 22 to the board I4 and is kept from swinging too far out at its bottom by a tape 23 fastened to the leg and to the board I4.
The member II consists, in the main, of an inner plate 24 of transparent plastic, such as Celluloid, and an outer plate of opaque material, such as plastic or cardboard 25, the plates 24 and 25 being united by a, peripheral tape 26. Plate 25 has a large central opening 2l in which is disposed an annular ring 28 of smaller outside diameter than the opening 21, leaving an annular track 29. Similarly a ring 30 is disposed in the ring 28, providing a track 3|. At its inner edge, at the bottom, ring 3D has a radially inwardly extending portion 32 provided with an arcuate track 33. While plates 24 and 25 are connected by tape 26, ring 28 is held-outwardly from plate 24 by a circular rib 34, fastened, as by cementing, to the inner face of ring 28, Rib 34 is a ring of smaller diameter than the large diameter, and of larger diameter than the small diameter of ring 28. Rib 34 is in turn secured to the transparent plate 24.
Since plate 25 is fastened to plate 24 only at its periphery, it can be moved outwardly relative to plate 24 about the edge of the hole or opening 2l. Since rib 34 spaces ring 23 outwardly from plate 24, the track 29 forms part of a dove-tail groove, see Fig. 2, formed by the track 29 and the spaces at either side thereof bounded by the plate 24 the plate 25 and the ring 28.
Ring 3i! is shown in Fig. 3, looking at its rear face. A ring-shaped rib 35 is cemented about its inner periphery, an arcuate rib 3&5 is cemented about the inner margin of the portion t2 and ller ribs 3l are cemented between the ribs 35 and 36 at the ends oi portion 32. These ribs 35-36-3l are also cemented to plate Zfi, so that track 3| is similar to track 2d, except it is of smaller diameter. Thus ring 23 is mounted between the margin of the opening 2l and the outer edge of the ring 3G.
When the rear member i2 is located behind the front member H, the picture i5 of the rear member can be seen through the ring 35i and the center of the transparent plate 2, as shown in Fig. 1.
`Two buttons 33 and 39 are disposed, one in each of the tracks 29 and Si respectively. A similar button it is disposed in track 33. The buttons are best shown in Figs. 4 and 5. This button will be presumed to be button 38, but it will be understood that the three buttons are similar. The button has a laminated head ii formed of a plurality of layers of cardboard, plastic, or the like, cemented together, seven layers being shown by way of example. The head is raised to provide a knob d2 in its center to provide additional thickness at its center. A tack 43 is associated with the head to form the button, the tack having a base lili, a pin it and two opposite cams at thejuncture of thebase andpin. The cams @6 engage the adjacent lamination of the head. The cams extend the diameter of the pin when it is turned, but the minimum diameter is the diameter of the base of the pin, as is ciearly shown in Fig. 5. laminations of the head partly by being driven therein, and partly by the cement holding the laminations together.
Each button is dispo-sed in its track so that the base dit is in the dovetail groove and running along the outer face ci the plastic sheet' 24, see the button in Fig. 2. The cams and the hase of thepin in the track and the head verrides the adjacent portions on either side of the track. Thus the head of button overlaps plate andrring the head o button overlaps rings 29 and Se; and the head or button overlaps the two portions of portion on opposite sides ci track The operation of the calendar is as ioliows:
The man using the nrst opensit up and inserts the photograph or picture o his choice into the frame E5, via the slit l-e then closes it and stands it up with the frame braced by the leg 2i. then sets the calendar ior the current date. Then he moves button to the correct day name. He turns the button slightly so lthat the cams c5 iam in the track Sii lightly to prevent unauthorized movement of the button llt. He then moves button $59 to the correct month and the button 3S to the correct day and turns each button to actuate the cams le there- Each day, button 33 is moved one number and button il is moved one space. Each month, button 39 is moved one space. The photograph is visible through the plate 2t rand is framed by the inner edges of the ring Si) and portion 32.
While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modiiications lcom-l The pin is has in the ing within the scope of the invention as dei-ined in the appended claims.
