HARRY BENTON YOUNG, OF MOUNT HOLLY, NEW JERSEY.

CALENDAR.

T 0 all whom it may concern:

Be it known that I, HARRY BENTON YOUNG, citizen of the United States, residing at 212 Clifton avenue, Mount Holly, in the county of Burlington and State of New Jersey, have invented certain new and useful Improvements in Calend ars, of which the following is a specification.

My invention relates to calendars, more particularly to that type of calendar which is known as perpetual, and it consists in the combinations, constructions and arrangements herein described and claimed.

The object of my invention is to provide a device which is compact and convenient and by which any day of any year (the number of years available being limited only by the size of the card) can be determined with ease and accuracy, and without the necessity of mental calculations, or the liability of making error through the incorrect tracing of intersecting columns. I accomplish this object by arranging two charts or diagrams so that in certain relative positions sections on one chart are adapted to register with sections on the other chart, whereupon the desired information can be immediately and directly read off from the proper chart which contains it.

My invention is illustrated in the accompanying drawings in which Figure 1. shows a )lan of the larger chart,

and Fig. 2 shows a p an of the smaller chart.

Referring now to Fig. 1, I have shown therein a disk of septagonal shape and de noted in general by A. From the seven corners of the disk radial lines, a, extend inwardly toward the center, 6, terminating about half way between the center, 7), and the corners, c, of the disk. The seven divisions thus provided contain. certain numerals, the latter being arranged according to the following plan: The two outer rows of each of the seven divisions contain numerals representing years of the nineteenth century i. 6. years from 1800 to 1899. The next three rows contain numerals representing years of the twentieth century t. 0. years from. 1900 to 2000. Between the fifth row of numerals and the center, I), is the name of a day in the week, the names in adjacent sections following each other in regular order, reading from left to right or clockwise.

Fig. 2 shows another disk B which is also 'referably of septagonal shape. The radial lines a from the corners also divide this disk Specification of Letters Patent.

into seven sections each containing numerals and abbreviations of .the names of the months. The outer row of each section contains numerals representing days of the month, while between. these rows and the center I) are abbreviations and names of the various months together with a numeral desi nating the number of days in the articu ar month with which it is associate I construct my improved calendar by placing the disk B upon the disk A and passmg a pivot pin through their centers. The smaller disk B may then be rotated about its center until its radial lines a register with the lines a of the larger disk or until its sectliorlis register with the sections of the larger C1S In order to show the use to which the cal endar may be put I will take a concrete case. Sup ose it be desired to find out what day of tie week the 24th of October 1857 fell upon. The year 1857 is first located and then the smaller disk B is turned until the section marked Oct. registers with that containing the year 1857. Now if the 24th day of the month be found, the day of the week on the large disk, immediately above the numeral 24. on the small disk will be the day wanted. In this case. it is Saturday. It will be observed that certain years are inclosed in circles. These are the leap years. The months of January and February have two sections each on the small disk. When a leap year is taken and in connection therewith either one of the months of January or February then only that month which is starred should be used: Thus for finding the day of the week upon which Feb. 1 1, 1888 fell. that section. of the smaller disk containing Feb. should be used. Obviously when a certain day is given the date corresponding to it can be found by my calendar, this being merely a reversal of the process al ready explained. Other years may be add ed to the calendar by enlarging the larger disk The two disks may be of circular or other shape without departing from the spirit and scope of the invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is:

In a calendar, a large and a small disk pivotally connected together and each being divided into exactly seven exposed sections by radial lines, the sections on one disk being adapted to register with those on the other, numerals re resenting years, and the ary and February each having distinctive name of a day of t eweek'm each sectionofy marks in the sections required to be used the larger disk, of said numerals those repre- With the leap year numerals.
