To all whom it may concern:

Be it known that I, AL'rHEa Minter,

citizen of Newfoundland, and a resident of the city of New York, borough of Manhattan, in the county of New York and State of New York, have invented certaiiriieimand useful Improvements inCalendars, of which the following is a specification.

The object of this inventionis to provide a convenient reminder of the current month day and week-day by means of a device which may be associated with a watch-cover or other convenient support. A furtherobject is to provide this device in a structure having few parts and in which the monthday and week-day may be displayed in relatively large characers.

In the accompanying sheet of drawings which forms a part of this application,

Figure 1 is a view of the back of a watch, the cover of which carries a device embodying my invention;

Fig. 2 is an edge View of the watch, the back cover and calendar disks being in section- Fig. 3 is a view of the month-day disk;

Fig. 1 isa view of the week-clay disk;

Fig. 5 is a View of a modified form of month-day disk; and

Fig. 6 is a view of a modified form of week-day disk.

The device embodying my invention is shown associated with the back cover a; of a watch. Anionth-day disk I) carries on its.

month. This disk may be of celluloid, aluminum, or any other suitable material, and as shown it may be reinforced at the center by a disk 0 of fine light colored silk, linen or-muslin, and may be properly backed to prevent scratching. The disk is carried by a spindle cl upon which it is suitably and removably mounted, and this spindle is journaled in the cover and has a milled head 6.

Concentric with the month-day disk and superimposed thereon is a week-day disk 7 loosely mounted on the spindle, but having sufficient friction therewith to prevent undesired rotation in respect thereto. This disk bears'the names of the days of the week as ordinarily abbreviated, and is provided with teeth 9 g on its periphery.

In the cover is an opening h through which the name of "week-dayjmay be seen, and an reflies Wliih ieiu aide e s 5 t assoclated dig ts and .no more forming the designationof an onth-day o be seen. This opening also, afl ordsaccess to the teeth of the weekday to permit thelatter to be tby inse tin t e P n of a r m Two arrangements of digits for representing'the days of the monthare shown, In Fig. 3 is shown an arrangement forsetting to successive days by right-hand or clockwise rotation of the spindle knob except for three: transpositions, where itis necessary to turn back for 12 after 11, for 14 after 13, and for 23 after 22. If all the 31 days of the month were separately provided for on the disk, then with the necessary spacing each digit could be given an angular space on the disk amounting to one-sixty-second part of the periphery. But it will be seen that by the rearranging shown each digit can occupy o1'1e-forty-eighth partof the periphery, and can therefore be proportionately larger. This gain in the main results from the elimination of separate digits for representing the month-days from 1 to 9 inclusive, and suitably inserting spaces after the numerals 21 to 29 inclusive so that digits 1 to 9 inclusive which are associated with these numerals may be displayed singly through the opening in the cover. Further gain results from having a digit 1 associated with the numeral 12 to provide for the numeral 11, in having a digit 2 associated with the numeral 23 to provide for the numeral 22 and in having the digit 3 of the numeral 13 associated with th digit 1 of the numeral 14: to provide the numeral 31.

In Fig. 5, is shown an arrangement of the digits and numerals for settin to successive days by left hand or counter c ockwise rotation. With this arrangement the transpositions required in the case of clockwise rotation are eliminated. 1

For convenient setting of the week-day disk, the week-days should read the opposite way around from the month-days, the week day disk of Fig. 4 being used with the month-day disk of Fig. 3, and the weekday disk of Fig. 6 being used with the month-day disk of Fig. 5. However, owing to th fact that the designations on one of the two associated disks is read above the center and the other below the center, the direction of rotation of both disks in consecutive setting is the same.

Sp ecifica'ti on of Letters Patent. Patgntgd 25, 191$,

The foregoing detailed description has been given for clearness of understandm U and no undue limitation should be'deduced therefrom, but the appended claims should be by Letters Patent of theUn'i'ted States, is '1. The combination ofa month-day disk bearing digits for representing the days'o'f the month, the digits'being in such Sequence and with such spacing that one set of digits for representing'the' month days from 1 to 9 inclusive also Will-form parts of two digit mo'nth-da designations, a cover having-an opening t' rough which two consecutive digits may be seen, and means for setting the disk, substantially as described.

4 2. The combination of amonth-day-disk new, and desire to secure bearing digits for representing the days of the month, the digits being in such sequence and nude such spacing that one set of digits for, representing the month-days from 1 to 79 inclusive also will iorm parts of two digit numeral 31, a over having an opening through which two consecutive digits may be seen, and means for setting the disk, substantially as described.

I Signed at-New York, New York, this th day of July, 1916 ALTHEA MILLER.

C opiesof this patent may be obtained for five cents each, by addressing the Commissioner of Patents,
