PERPETUAL CALENDAR.
SPECIFICATION forming part of Letters'Patent No. 579,257, dated March 23, 189'?.
Application filed October 12, 1896. Serial No. 608,612. (No model.)
To @ZZ whom t may concer-11,.'
Be it known that I, WILLIS HUsToN COLBY, a citizen of the United States, residing at Littleton, in the county of Grafton and State of New Hampshire, have -invented certain new and useful Improvements in Perpetual Calendars; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention has relation to improvements in calendars for ofce, counting-house, and general use; and the object is to provide a simple, convenient, and ornamental device of this kind.
4To these ends the novelty consists in the construction, combination, and arrangement of the same, as will be hereinafter more fully described, and particularly pointed outin the claim.
In Jthe accompanying drawings the same iigures of reference indicate the same parts of the invention.
Figure 1 is a perspective view of my improved calendar. Fig. 2 is a central transverse section of the same, and Fig. 3 is a detail view of the central spindle.
l represents the frame, and 2 a sheet-metal face-plate secured to the face of the frame by the iinishing-screws 3 3.
4 represents the central spindle, journaled in a vertical oblong hole 5 in the face-plate and provided at one end with a thumb-button 6, its rear end being provided with a serrated disk 7, which revolves freely when the button 6 is rotated in either direction. The
face of this disk is provided with the days of` the month in numerical order, and S represents an arc-shaped orifice in the face-plate by means of which seven of the dates correspending to a week can be read off on the disk.
Immediately above the orice S are arranged the days of the week, as shown, and which correspond to the seven dates seen through the orifice 8, so that by setting the disk with the appropriate date inline with the first day of the week on the face-plate the correct dates for the remaining days ofthe week can be readily seen at a glance.
9 is a stationary stud on the back of the face-plate, which engages the serrated rim of the disk and locks it in place when once ad justed and prevents its accidental displacement. To adjust the disk, button 6 is pressed downward in the oblong hole 5, which releases the upper edge of the disk from the stud 9, allowing it to rotate freely in either direction to set it, and after it is set a spring 10, secured to the back of the face-plate, presses against the spindle, holds the serrated edge against the stud, and prevents its turning.
12 represents a dial on the face-plate containing the months in the year, and 13 represents a disk mounted on a stud lain front of said dial. This disk is formed of any suitable opaque material, and a radial recess 15 is formed in said disk corresponding to a single month in the year. The material which is cut away to form said recess 15 is bent outwardly at a right angle to form an integral handle 1G, by means of which said disk may be conveniently operated.
In the lower leftl hand of the face-plate is a small rectangular opening 17, and on the left of this opening is arranged a component part of the figures .representing the year. In this instance the figures are 1539- while the ten digits are arranged in circular form on a dial 18, mounted on a shaft 19, extending through the face-plate and provided with a thumb-button 20, by means of which the dial 18 may be rotated to present the appropriate iigure to the opening 17 in line with the fixed figures and complete the date corre-sponding to the year. l
Although I have specifically described the construction and relative arrangement of the several elements of my invention, I do not desire to be confined to the same, as such changes or modiiications may be made as clearly fall within the scope of my invention without departing from the spirit thereof.
Having thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States, 1s
A calendar comprising the frame, the faceplate 2 secured thereto and provided with the stud 19 and arc-shaped orifice 8, the days of the week arranged above said oriiice and having oblong hole 5, in combination with the IOO spindle 4 mounted in said hole, the spring l0, In testimony whereof I hereunto afx my in Contact With said spindle, the serrated signature in presence of two Witnesses. disk 7 mounted on said ssndle and havin@ the days of the month arrlztnged on its faoe- VILLIS HUSTON COLBY' 5 and the thumb-button 6 secured on the outer Witnesses:
end of said spindle, substantially as md for A. J. BARRETT, the purpose set forth. WM. G. GREENLEF.
