UNITED STATES PATENT- Orricis.

ARISTA H. ISBELL, or ASHEVILLE, NORTH-CAROLINA, ASSIGNOR TO JOHN HART AND R. E. BOWLES, OF SAME PLACE.

PERPETUAL CALENDAR.

SPECIFICATION forming part of Letters Patent No. 373.235, dated November 1 5, 1887.

Application filed June 1, 1887. I

' To all whom it may concern.-

Be it known that I, A Is'rA H. ISBELL, a citizen of the United States, residingat Asheville, in the county of Buncombe and State of North Carolina, have invented certain new and useful Improvements in a Perpetual Calendar and Business'Notifier; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable IO others skilled in the art to which it appertains to make and use the same.

This invention relates to that class of calendars which show at a glance the day both of the week and the month and which have pro- I5 vision for changing the relation of the weekly and monthly indices, so that the days of the week may be set to register properly with the days of any month in any year, thus making the same a perpetual calendar.

The object of the invention is to aid the memory of business men, or to preserve memoranda of future events in such a manner as to relieve the memory and be sure to call attention to any necessary duty or occurrence at the proper date therefor.

To this end theinvention consists in the construction and arrangement of parts forming the perpetual calendar and business-notifier hereinafter described and claimed, reference being had to the accompanying drawing, which is a perspective view of my invention.

to represents a tablet of wood, sheet metal, stiff pasteboard, or any other suitable material, of any size or proportions adapted to the service required of it. I prefer to make it of very heavy paper-board, and twenty by thirty-four inches would be a convenient size. a represents a series of vertical lines, and b a series of horizontal lines, dividing the central portion of the tablet into rectangular checks e. The first horizontal line of these checks is numbered from 1 to 7, the second line from 8 to 14:, and so on up to 31, the largest number of days in a month.

0 represents a cylinder journaled in an incasement, d, which is fixed upon the tablet above the checked portion e. The names of the days of a week are arranged in order in zones around the cylinder above and registering with the columns of checks e, and the in- Serial No. 239,965. (No model.)

casement d is provided with a horizontal line of'apertures registering, respectively, with the said zones, each aperture exposing'a single name of a day. The successive zones are arranged so as to bring the names of the days of a week in their proper order of rotation opposite to the aperture in the inoasement, so that the cylinder may be turned to bring any day of the week above the first day of themonth, when the other days will register with the proper monthly numerals, and the succeeding weeks of the month will also be headed by their corresponding days,

f representsa pocket in or secured to the incasement d to receive twelve cards, each having the name of a month marked on it. The front of the pocket has a window, 9, to. expose to View the name on the front card in the pocket.

h represents a series of hooks secured to the tablet to project from its face, one hook in each of the checks numbered and appropriated to a day of the month. This is a principal feature of my invention. These hooks are intended to receive cards or slips of paper on which any memorandum is made. Whenever the owner of this device thinks of any occurrence to. take place of which he wishes to be notified on a given date, he makes the nedessary memorandum on a slip of paper and places it on the hook of that date. Thus appointments made, moneys due, and every important event expected is recorded. Then each day the person examines the memoranda for that day accumulated on the hook and is prepared to fulfill his engagements. These hooks will always serve for one full month, for if we are in the middle of a month we may use the past hooks for next months engagements.

It represents a pocket in which such notifiers as have been used, but may still be needed for future reference, may be stored, or in which blank notifier-cards may bekept ready for use.

Z, m, and n represent pockets for mail purposes to hold letters in different stages of passage.

I am aware that hooks have before been arranged in connection with numbers for various purposessuch as for hotel room-keys, clothing-checks, 8m; and I am further aware that 100 knobs have been shown as placed upon a calendar in an irregular manner not adapted for perpetual service, and I do not claim such hooks or knobs, broadly, as my invention; but

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, in a calendar, of a tablet marked by a series of horizontal and vertical lines into columns of checks, the said cheeks being numbered according to the days of a month, a cylinderjournaled in an incasement which is secured across the tablet above the columns of checks, the said cylinder being divided into zones corresponding in width to the width of the columns of checks to register therewith, each zone being marked with the names of the days of the week in their order, and the successive zones from left to right being arranged with the names of the days of the week, reading in order in horizontal lines, the said casement being provided with a pocket having an opening in its front and located above the said roller, wherein cards marked each with the name of a month may be placed, substantially as shown and described, whereby the calendar is made perpetual.

2. The combination, in a perpetual calendar. of a tablet marked into columns of checks numbered to correspond with the days of a month, a cylinder marked with the names of week-days above the said columns and adapted to show the said names of week-days in every order of rotation, and hookssecured to project from the tablet in each check thereof, substantially as shown and described.

3. The combination, witha tablet numbered as a monthly calendar and a cylinder having the names of week-days marked on it and adapted to register any day of the week with any day of the month, of a hook secured to the tablet at each monthly number, substantially as shown and described.

4. The perpetual calendar comprising the checked and numbered tablet, the week-day cylinder, and the hooks secured at the monthly numbers and having a notifier-pocket, k, secured upon the tablet, substantially as shown and described.

5. The perpetual calendar comprising the checked and numbered tablet, the week-day cylinder, and hooks secured upon the tablet at the monthly numbers and having the mailpockets Z, m, and a secured to the tablet, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

ARISTA H. ISBELL.
