CHARLES D. WILLIAMS, 0]? SALIDA, COLORADO.
To all whom it may concern:
Be it known that I, CHARLES'D. VVIL- LIAMS, a citizen of the United States, residing at Salida, in the county of Chaffee and State of Colorado, have invented certain new and useful Improvements in Calendar Date-Indicators, of which the following is a specification.
This invention relates to improvements in calendars, and has for its prime object the provision of an attachment for a calendar by means of which"tl1e date is positively indicated.
Another object is the provision of a detachable device for a calendar carrying a sliding indicator adapted to be moved over the date numerals and the provision of means for ready attachment or detachment of the device.
A still further object is to provide a separate indicator for the days of the week.
These and other objects will be apparent from the following description, and with reference to the accompanying drawings, but it will be understood that changes in the specific structure may be made within the scope of the claims, without departing from the spirit of the invention.
In the accompanying drawings, forming a part of this specification, and in which is illustrated a device of this character, made in accordance with the preferred embodiment of my invention, Figure 1 is a front elevation of a calendar having my device applied thereto. Fig. 2 is a vertical sectional view on the line 2-2 of Fig. 1. Fig. 3 is an enlarged sectional view on the line 33 of Fig. 1. Fig. 4 is an enlarged detail view of the date and day indicators. Fig. 5 is a longitudinal sectional view through the upper guide rod. Fig. 6 is a detail of a modification of the clips.
Referring particularly to the drawings, 1 represents a calendar, consisting of the usual number of sheets, and having printed thereon, the days of the week, and the dates of the month.
It is the prime object of this invention to apply the device to be later described to the collection of monthly sheets, in such manner that certain parts may be moved over the day and date markings, so that same may be discerned at a glance and from a distance.
A frame 2, consisting of a single piece of stiff wire, or other suitable material, is

bent into U-shape to form the upper and lower guide rods 3 and 1- respectively, and the end connecting member 5. The end member 5 is provided with clips 6 which are formed of single pieces of metal bent as at 7 to form the resilient gripping leaves for engagement with the edges of the calendar sheets. In Fig. 6, it will be seen that clips may be formed by bending the end member 5 as at 6. At the upper and lower ends of the rod 8 are the tubular members 9 adapted to be slipped onto the adjacent ends of the upper and lower guides 3 and 4. These tubular members have openings running through them so that the guides 3 and 1 may pass through when adjusting the frame to narrower calendars. A sleeve 10 is mounted to slide on the upper rod 3, and is provided with vertical connecting rods 12 having their lower ends connected to a second sleeve 11 on the lower rod 4. This forms a frame adapted to slide across the calendar sheet on the guides 3 and A. To position this sliding frame in proper place, the upper rod 3 is formed with a series of notches 13 which are engaged by a leaf spring 14L having a downturned portion 14;. These notches 13 if desired, may be disposed of and the frictional contact of the spring 14 against the rod 3 deemed sutficient to hold the sliding frame in any of its adjustable positions.
Tn the upper end of the sliding frame, and secured between the vertical rods 12, is a day indicator 15 carrying a piece of colored glass or lens as desired which when the frame is moved horizontally over the vertical line of dates will be positioned over the days of the week. Mounted to slide vertically on the rods 12 is a small frame 17 which has the tubular members 18 mounted on the side rods 12, and secured therebetween a similar holder to the one just described for carrying colored glass or a lens. This frame 17 is adapted to slide vertically to be positioned over any one of the dates on the calendar in connection with the horizontal movement of the first mentioned sliding frame. One of the tubular portions 18 is provided with the spring gripping finger 13 similar in construction to that on the sleeve 10 and is adapted to hold the frame 17 in any of its'vertical adjustable positions.
From the foregoing, it will thus be seen that when the frame including the guides 3 and A on the end members 5 and 8 is properly adjusted on the calendar, the frame including the sleeves 10 and 11 is moved horizontally across the sheet, to the vertical line of dates containing the date to be indicated whereupon the lower lens carrying frame 17 is moved vertically until over the proper date. The upper lens is stationary in the sliding frame. This will always be in a line with the days of the week, and under the two indicators which when properly positioned, the date and day may be ascertained by a glance at the calendar and from a great distance, the lenses magnifying the printed days and dates of the calendar so that they may be readily seen. If plain or colored glass is used, the relative positions of the frame 17 will indicate the particular date.
By means of the adjustable feature at one end of the main frame, the device is adapted to be applied to calendars of various widths, and if desired, the members 5 and 8 and the rods 12 may be made to telescope so that the frame will be capable of adjustment vertically as well as longitudinally.
The calendar sheets are formed with semicircular notches 19 centrally in their upper edges. so that the leaves may be turned over and be permitted to pass the hanger 20.
What is claimed is:
1. An attachment for a calendar having vertical and horizontal lines of dates, said attachment comprising an adjustable frame having clips for engagement with a calendar, a sliding member on said frame adapted to be moved over the horizontal line of dates, notches in said first named frame adapted to be engaged by means on the sliding frame to position said sliding frame over said line of dates, a vertically slidable member carrying a lens and mounted to slide on said sliding frame, said slidable member adapted to be positioned over the vertical lines of dates, and means on the lens carrying member for engagement with the sliding frame to hold said lens member in any of its adjusted positions.
2. An attachment for calendars having a horizontal line of week day names, and vertical and horizontal lines of dates, said attachment comprising an adjustable frame having clips for engagement with the edges of a calendar, a sliding frame on said adjustable frame, said sliding frame adapted to be moved horizontally across the calenda) and be positioned over the vertical lines of dates, a lens carried on said sliding frame, said lens being stationary on said frame and adapted to be positioned over the days of the week, a vertically movable lens on said slidable frame adapted to be positioned over one date of any one of the horizontal lines of dates, means for holding the sliding frame in its adjusted positions, means for holding the vertically movable lens in its adjustable positions, and means for holding the frame together in its different adjusted positions.
In testimony whereof I aflix my signature, in the presence of two witnesses.
