Attomey Patented Oct. 13, 1936 UNITED STATES PATENT OFFICE 2 Claims.

This invention appertains to new and useful improvements in calendars of the perpetual type.

The principal object of the present invention is to provide a calendar of simple and inexpensive construction to the end that it can be manufactured and distributed in the form of advertisements.

Another important object of the invention is to provide a perpetual calendar which while of simple and inexpensive construction, has its parts arranged in such a manner that it Will be both positive acting and durable and have all of the conveniences of a much more elaborate mechanism.

During the course of the following specification and claims other important objects and advantages of the invention will become apparent to the reader.

In the drawings:

Figure 1 represents a front elevational view of one form of the invention.

Figure 2 represents a vertical sectional view through the form of the invention shown in Figure l.

Figure 3 represents a rear elevation of the form shown in Figure l.

Figure 4 represents a rear elevational view of the modified form of the invention.

Figure 5 represents a vertical sectional view through the form of the invention shown in Figure 4.

Figure 6 represents a front elevational View of the pendulum member used in both forms.

Figure 7 vrepresents a front elevational view of the disk employed in both forms.

Referring to the drawings wherein like numerals designate like parts, it can be seen that the calendar consists of a plate 5 of cardboard or some similar cheap material having a substantially rectangular shaped opening 6 on the lower portion thereof, above which is an arcuate shaped slot 1.

On the back side of the board 5 is a longitudinally tapering pendulum 8 having its upper end secured to the stud S which passes through the plate 5 and is equipped with a small knob IIJ at its front end.

Between the board 5 and the pendulum 8 is located the disk II which has the stub shaft I2 extending therefrom and through the board 5 to terminate in a knob I3 at the front side of the board.

A guide for the free end of the pendulum 8 is located on the back side of the plate 5 and consists of two strips I 4-I5, the latter being secured upon the former, and both secured to the back side of the plate 5 by adhesive, with the strip I5 overhanging the upper edge portion of the strip I4 so as to provide a guideway for the lower portion of the said pendulum 8.

Stop strips lli-I6 are also glued or otherwise secured to the back side of the plate 5 beyond opposite longitudinal edges of the pendulum 8.

On the pendulum 8 is the chart I'I of days of the month, while on the disk II is the annular arrangementof months I 8 of the year.

Figures 4 and 5 show a slightly modied form of the invention wherein the stops I6-IE are eliminated and substituted by short ear extensions I6' I6 at the lower corners of the pendulum 8 and these are capable of abutting the ends of the guide strip I4 to limit the motion of the pendulum.

Figure 3 shows a supplemental guide for the pendulum 8 consisting of a strip I9 of cardboard disposed across the pendulum and a strip 20 of adhesive secured along the cardboard strip I9 and having its end portions 2I adhering to the back side of the plate 5.

Obviously the pendulum 8 serves as a backing for the disk II, amply supporting the disk against the plate 5.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit or scope of the invention as claimed hereinafter.

Having thus described my invention, what I claim as new is:

1. An indicator comprising a wall having a pair of openings therein, a rotary disk mounted on the back of the wall, and a pendulum pivotally connected at one end to the back of the wall and adapted for disposition across the back of said disk to retain the disk against the back of the said wall, said disk and pendulum having indicia thereon visible through the openings in the wall, and guide means engaged with the pendulum for holding the latter against the: disk.

2. An indicator comprising a wall having a pair of openings therein, a rotary disk mounted on the back of the Wall, and a pendulum pivotally connected at one end to the back of the wall and adapted for disposition across the back of said disk to retain the disk against the back of the said wall, said disk and pendulum having indicia thereon visible through the openings in the wall, and guide means on the back of the Wall at a point diametrically across the disk from the point at which the pendulum is secured to the wall, said guide being adapted to receive the free end of the pendulum.
