` T0 ALL WHOM IT MAY CONCERN:

Be it known that ISIME 0N L. BARINDS, of St. Joseph, in the county of Buchanan, inthe State of Missouri,

' have invented. an Improved Perpetual Calendar; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a. part of this specification, in which- Figure 1 is a plan view of my calendar.

Figures 2 and 3, a view oi' the device which operates'the dials. I

This invention relates to a newmethod ofascertaining the day of the week when the month and year are given, and in the use oi novel `means for turning the dials.

In ordor to givenl correct understanding of my invention, I have marked corresponding parts with similar letters, and will now give a detailed description. I

A., drawing represents the front of aeommon picture-frame, which supports the calendar and the oper ating arrangements. 'An out'er card-board, E, is made fast to said frame independently of the dials B D, and has a. series of figures and letters marked on it, as will be hereinafter described.

A dial, B; rawinglA, is placed inside of the card-board E, and made fast te'a screw-wheel F, gs. 2 and 3, drawing B, "in order that said dial may be turned around by means of a screw, H, having a knob, K, projeciing outside ofthvframdill, shown vby a broken" section. The small dial D is made to project through the card-board E, :andlvis fastened to a post, L, that-it may turn independently of the dial B, when operated upon by a, grevv wh' eel, G, and yscrew- I, made similar to H.' This arrangement 'is quite simple, yet provides very convoriientmeans' operating tho dials.

'The letters andiigures marked on the face of the card-board consist, first, of two tables, Y' X, having seven columns of fig-urea' each, the columns maud' 7i, drawing A,being numbered 'from l to 28, inclusive. The v:remainder-ei' thecolumns in table X are all together numbered from 1709 to 1876, inclusive, and the balance of table Y from '11.877 to 2044, this la'tterbingthe future scope of the calendar.- It also has the months marked on it., The circle R vhas sevencolumns,of figures marked on it, as follows: Column P has the figures 1, 8, 15, 22, 29; column. O, 2,- 9, 16,l 23,30; column U, 3,710, 1.7, 24, 31; column 1,'4, 11, 18, 25; column S, 5, 12, 19, 26; column r, 6, 13, 20, 27;A coluinnfQ, .7, 14, 21, 28.

The small diixl D is divided in seveuparts, and marked with letters indicating the days .of a week. T- he inner dial B has the figures fre'ml to 28 marked on its face near the periphery, and twenty-eight divisions, in

which arc marked the days of the week, as seen at iig. 3; drawing B.

v *i I Operation.

The following examples will show how the calendar is Vto be worked to 4find whatday of the week the .13th day of November, 1867, fell on. l'n'thc reference column, 1867 is placed opposite 19. Turn the dial B until the column :t9-appears in the space Y; this Vshows that the 1st day of November fell on Friday. Then turn dial D until Friday is opposite 1 on dial R, which shows that the 13th day fell on Wednesday. Again, to yfind-what day of the week the 4th day of March, 1877, will full on. It will he seen by the reference table that 1877 is placed opposite 1 in column P. Bring` 1on dial B 'iutospaec Y', and it will be seen that the 1st of March falls on Thursday. Then turn dialD'until Thursday is opposite 1 OuR, and it will be seen that the 4th of' Mar'ch falls on Sunday.

Having thus described my device, what I claim, and desire to secure by Letters Patent, is-

1. The combination et' the cardboard E and dials D B, havingr letters and figures marked on them, substantially as and for the purpose set forth. Y

2. The combination of screw-nhools F G, screws H I, and dials DB, substantially as .set fortn.
