Description
Yurrnn STATES JOHN H. MEAD, 0F NEV YORK, N. Y.
IMPROVEMENT IN CALENDARS FOR. ALMANACS.
Specilication forming part oi' Letters Patent No. dtd., dated November' 15, 1864; antedated November 3, l8h4.
To all whom it may concern v .Be it known that I, JOHN H. MEAD, of the city, county, and State of New York, havein Vented a new and Improved Construction of Revolving' or Perpetual Calendar; and l do hereby declare and ascertain the saine, referrin g to the accom panyingdrawings, in which- Figure 1 is a vertical section. Fig. 2 is a front elevation of said calendar connected with an inkstand suitable for counting-room purposes.
My improvement consists in the mode of constructing and arranging the parts of the well-known perpetual calendar so as to render it convenient and durable, and easily and cheaply constructed and combined. For this purpose I use iron or other suitable metal cast in short cylindrical or frustum cups.
The construction is as follows: The exterior gure being iirst determined, (in the drawing it is conical,) l form a hollow base, A', which may contain a suitable inkreservoir, (l. Above the base A there is a cylindrical cupt'ormed casting, A, having concentric with its center a projecting ring, a c, which rises perpendicularly up from the bottom, as clearly seen in the section,Fig. 1, to a height greater than the outer rim. Upon this section A, l impose a second one, A, of precisely similar form, but in the drawings shown smaller, to comport with the outline ot' the iigure. This rests upon the ring c a., above named, and is surm-ounted by twomore similar cylindrical sections, A A. It will be noticed that this form and arrange- I ment of parts leaves an open space all around the circumference of the section A. These spaces are filled by an ornamental molding or projection, b, formed on the circumference of a disk, c, that has an aperture in the center surrounding` and titting the ring a c. From the molding b projects downward a plain cylindrical ring, B, (see Fig. 1,) just within the outer rim of section A A. Bolt o extends down through the center from the top (which may be surmounted with a waferbox or other de vice) to the base, thus securing the base and sections A A A im movably together, and leaving the rings B iree to be turned by the molding b. On the front of each of the sections A the rim is cut out so as to expose to View the interior ring, B, at that point. On one of these interior rings may be marked the days otl the week, the months on a secondzone, the days ot the month on the third, and the years on the fourth. rlhis is clearly illustrated in Fig. 2. By turning the ring B by means ofthe molding the proper numbers are exhibited.
Having thus fully described my improved construction of calendar, what I claim there in as new is The combination and arrangement of the stationary sections A and revolving rings B, constructed as and for the purposes set forth JOHN H. MEAD.
