' CALENDAR.

SPECIFICATION forming part of Letters Patent No. 301,553. dated July 8, 1884-.

Application tiled October 8.1883.

To a/,ZZ whom it mayconcern:

Be it known that I, THOMAS A. BnnEMAN, a citizen of the United States, residing at Mount Pleasant, in the 'county of4 Henry and State of Iowa, have invented certain new and useful Improvements in Perpetual Calendars, of which the following is a description.

My invention relates to that class of calendars which are arranged to have the days of the week and ,mont-h changeable relative to each other, and the object of my invention is to show at a glance the different days of the month on which any day of the week occurs,

vand to be readily changed'to give the same information relative to any month of any past or future year. This is convenient in ascertaining the day of the week when any festival, holiday, birthday, 85e., will occur orhas occurred.

My invention consists in a frame, a series of number-bearing blocks, and a roller constructed and combined as hereinafter described and claimed, reference' being had -t0 the accompanying drawings, in which- Figure 1 is a perspective view of my calendar with one side removed. Fig. 2 is a side elevation of one of the blocks, and Figf is a perspective view of the roller. Y

A represents the frame with its right side removed.

B B are a series of shelves secured to the bach board of the frame, each shelf being "slanted from its front edge backward on its upper side.

, frame to extend across from side to side.

roller is a seven-sided prism, having all the' G is a roller journaled in the sides of the This days of the week marked-upon each side in order from left to right. The days also appea-r in regular order circumferentially in each of the seven zones about the roller. On that side on which Soni7 is the iirst at the left Sat. is the last at the right. 0n the next side Mon77 will 4be the first at the left and Sun.77 the last at the right, die. By this arrangement any day of 4the week may, by rotating the roller, be brought over any one of the seven columns shown below. These columns of gures are each upon a separate block,

(Model.)

E. The rst square on the face of each block contains one of the first seven numerals, each different from the other. These form a line. The next line on the same blocks contains the next-seven numbers, Sto. Thus the first thirtyone numbers are placed in lines, the succeeding numbers on each block being each seven larger than its predecessor. Each block E has a series of projections on its back slanted on their under faces, and spaced to register with and to rest upon the shelves B. The height of the extremity of each projection D is less than the space between the front edges of the shelves B, so that each block maybeseparately removed from the frame. By this means one or more blocks at either side may be removed, the balance of-the blocks .be slid along, and the block be placedat the opposite side. The distance from the top of one shelf to the top of the next corresponds to the height of the gures on the blocks, and the projections D being equidistant, any of the blocks may be placed on lower shelves than they are now shown. have the .week-days stand permanently with Sun. at their head, and suppose the incoming month begins -with Thurs., then four blocks as the'y now stand at the right should be placed to the left on the next line below, and the :First three at the left be slid across to the right, thus bringing 1"7 under Thurs and the other numbers all in their proper rotation. There are printed tables for sale at book-stores showing the day oi' the week on which the first day of each month occurs through a series of years reaching far into the past and future. By the use of such a table in connection with my calendar the day of the week may be quickly ascertained on which any future anniversary Willoccur. For instance, suppose we wish to know on what day Christmas will occur in 1890. By reference to a table we nd that December 1, 1890, is Saturday. Then taking my calendar, as shown in Fig. 1, move live blocks from the right to the next line below at the left. Then l77 stands under Sauf7 and the 25th- Having thus fully described my invention,

Christmas day-will be found to be Tuesday.

Thus, supposing it to be desirable to what I claim, and Wish to secure by Letters frame laterally to said blocks, said roller hav- Patent, s ing the days of the Week marked on it, sub- The combination, with a series of blocks stantially as and for the purpose specified. marked with figures representing the days of THOMAS A. BEREMAN. 5 the month, a frame, and means, substantially Vitnesses:

as described, for holding said blocks therein, SAM-I. SHANER, in combination with areller journaled in said C. V. ARNOLD.
