PROGRAMME-crock.

SFECIFICATION forming part of Letters Patent No. 292,456, dated January 22, 1884;,

Application filed Xovembcr 30, 1883. X0 model.)

I0 (6 whom, it may concern.-

Be it known that I, THEODORE XVILMER, a citizen of the United States, residing at Millhousen, in the county of Decatur and State of Indiana, have invented new and useful 11nprovements in Programme-Clocks, of which the following is a specification.

My invention has forits object to produce a programme-clock which will not only strike the hour or time for the ending of one and conr meneent of another exercise or recitation, but will also show at a glance the different recitations for one or more days, the time to be devoted to each recitation, and the order in which they follow each other, so that more than a limited time will not be unintentionally devoted to one recitation, and so that the recitation to follow next in order being known, preparation therefor may be made; and to the accomplishment of those ends the invention consists in a dial-plate or map made into divisions or sections corresponding in number to the days or school-days of a week, marked on a movable hand or pointer, which may be the hour or minute hand of a clock or alarm mechanism, the said sections or divisions being adapted to be marked with the recitations for a given day, and eachin extent being such that when the allotted time for a particular recitation has elapsed the hand or pointer will have traveled the distance representing the time assigned to that recitation.

A detailed description of means for carrying out my invention'willbe hereinafter given.

The accompanying drawing represents a front elevation of a clock, such as the Estell programme-clock, with my dial-plate or map applied thereto.

The alarm or clock mechanism may be of any approved construction for striking an alarm at stated intervals in accordance with a predetermined programmesuch, forinstance, as what is known as the Estell programme clock or regulator, for which patents were granted to S. F. Estell, January 11, 1870, No. 98,678,

and October 10, 1871, No. 119,833. To the face A of such a clock I affix a dial or map plate, A, made of sheet metal or other suitable material, having a central circular opening, B, to expose the dial-plate of the clock, and having its face preferably colored black,

made with a surface from which marks may be erased, and divided into a series of divisions, 0, by a series of circular lines, D, and into a series of colnmnsbya series of lines, E, radiating from the center of the dial-plate or map toward its periphery. In the drawing there are represented a suiticient number of circular lines to form five con centric divisions, one for each schoolday of the week, but any number of such divisions desired may be formed. These divisions are marked,respectively, with the days of the week,beginning with the outer division, which is marked Monday, 7 and continuing on down to the inner one, ending with Friday. The radiating col umns, orso many of them as are necessary, are marked with the lessons for the day. For in stance, take the outer concentric division, which is Monday. It is marked so that in one column there will appear the first recitatation for the day, Reading, inthe next section the following recitation, Arithme tie, in the next the recitation to follow the last, Penmanship, thenin the nevt, Grainmar; and, finally, Spelling. The above recitations are supposed to constitute all that there will be before the noon recess, and above each recitation is marked in figures the time allotted to eachfor illustration, thirty min utes for composition, and twenty minutes for penmanship. Then follows a blank space, in which will be marked the time allotted for recessfor illustration, one hour. and beneath that Free. Then follow the sections marked with the recitations for the afternoon, with the hour allotted to each, marked in the manner already described,- and next there may follow blank spaces, in which can be marked the hour for opening or closing, orsuch announcements as may be desired to be made. The concentric division next below the outer one will be marked in the respective columns with the recitations for the day which that division represents, and so on down the several divisions.

The recitations for the several days may be marked in different colors, so as to readily distinguish one from the other, and the marking may. be done with chalk or other substance that can be easily rubbed off, so that the programme of studies and their order may be changed as desired. At the lower or inner end of each section marked with a recitation there may be marked the initial letter of the recitation at the head of the section or column, or with whatever other exercises that may be desired, so as to indicate on the last schoolday of the week the lesson or recitation for the first day of the next week.

The hand or pointer of the clock will be extended to the outer division of the dial or chart plate, and will be divided into divisions marked and numbered correspondingly with those of the days of the week on the dial or chart plate. This movable hand or pointer is moved by the clock mechanism, and the alarm is set in the way usual in the programmec-locks hereinbefore referred to, so that thelength of timerequired forthe hand or pointer to pass from one section or column to the next will be the time alloted to the recitation marked in that column, and the alarm sounded when that period of time has elapsed.

The concentriclines and radiating lines will, by preference, be indelibly marked on the face of the dial or chart.

, It will be seen from the foregoing description that I provide a clock which will indicate the hours of the day, the recitations for one or more days, the order in which they occur, the time allotted to each, and which will sound an alarm at the ending of the time allotted to one recitation and for the beginning of the next recitation.

The device is simple and cheap of producti on, and can be attached to programme-clocks already in use at a comparatively small expense.

Having thus described my invention, what I claim is- 1. The combination of a dial plate or chart divided into a series of columns, and a series of concentric divisions adapted to be marked with one or more days of the week, with the recitations for one or more days in their sequence, and with the time alloted for each, a pointer marked with the days of the week corresponding to those that may be marked on the dial-chart, and any suitable mechanism for moving the pointer over the dial-plate,

so as to pass it from one column to the other,

to indicate when the time for one recitation has ended and that for the next arrived, substantially as described.

2. The combination, with a clock to indicate the hours of the day, of a dial chart or plate divided into a series of columns and a series of concentric divisions, adapted to be marked with one or more days in their sequence, and with the time allotted for each, a pointer marked withthe days of the week corresponding to those that may be marked on the dialchart. and mechanism for moving the hour-indicating hands of" the clock to indicate the hour of the day, and in unison therewith the pointer over the dial-plate. so as to pass it from one column to the other, to indicate when the time for one recitation is ended and that for the next arrived, substantially as described.

In testimony whereof I h ave hereunto set my hand in the presence of two subscribing witnesses.

THEODORE VILMER.
