COMPLETE SPECIFICATION,
A New and Improved Perpetual Calendar.
We HOWARD LAWRENCE WEED, Mining Engineer, and EDWARD
PITTWOOD, D.D.S. each residing at Spokane, in the County of Spokane, in the
State of Washington, United States of America, do hereby declare the nature
of this invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
The object of this invention is to produce a new perpetual calendar which while
possessing some of the attributes of the ordinary "hanger" or wall variety is
adapted for perpetual use. The hanger-card has on its face a stationary line of
lettering indicating the days of the week commencing with Sunday and terminating
with Saturday but instead of the customary tabs with numerals for each month
thereon, the card is provided with devices as hereinafter stated whereby the
necessary day dates can be adjustably presented as required.
According to this invention the hanger card is provided with the usual line of
day indicating lettering; it also has a plurality of slots or openings through which
the months and years are visible, and at each side edge a curved or rounded guide
bearing for the movable date strap, rotable discs pivoted on the rear of the card
and having on their faces respectively letters indicative of the several months of a
year, a series of numerals indicating the first three figures of a number of years
and a series of numerals from 0 to 9 indicative of the year terminals which latter
disc is positioned and arranged to rotate so as to bring the numerals thereon in line
with the numerals on the other numeral dise, an endless date strip loosely mounted
upon and surrounding the lower part of said card and adapted to slide across the
face and around the side edges thereof and having on its face a series of thirteen
date columns with dates so positioned thereon that as said strip is turned any seven
columns will present on the free of the card, and in the proper position relatively
to the stationary line of week days thereon, thirty one day dates and a supplemental
endless strip having a series of unnumbered squares or columns thereon corre-
sponding with the columns on the date strip and a pair of shoulders located one
square apart, vertically, and seven squares apart horizontally whereby said
unnumbered strip may be turned to cover the redundant numerals at either side of
the date strip according to requirement.
In the accompanying drawings:-
Fig. 1 represents a front elevation of a calendar constructed according to this
invention. Fig. 2 represents a rear elevation thereof.
Fig. 3 represents a plan view of the date strip in its entire length with the
edges disconnected.
Fig. 4 represents a similar plan view of the supplemental date covering strip.
Fig. 5 represents a plan view of the rotatable month-and-year-indicating discs.
Fig. 6 represents a top edge view of the complete calendar.
I represents the hanger-card which is provided with slots or openings 2, 3
through which the names of the months and the year dates, respectively may be
viewed. 4 represents a disc rotatably journaled at the rear of said card 1 and
having around its circunference the month names which register with the slot 2.
5 represents a smaller rotatable disk similarly pivoted to the card and having
thereon a series of numerals representing the first three numbers of a series of
years which register with the slot 3. 6 represents a smaller disc rotatably pivoted
on the said card and having around its circumference a series of numerals from 0 to 9
which as said dise 6 is rotated are, as shown in Fig. 1 brought into line with the

page_text: numerals on the disc 5. By this arrangement the calendar is adapted for use for a
great many years the number depending upon the size of the disc 5.
7 represents
a permanent and stationary line of lettering on said card indicating the days of a
week. 8, 9 represent curved or rounded guide bearings for the date strip to be
presently described. These guide bearings may be formed in a variety of ways
Euch for instance as by rearwardly-curving the side edges of the card and either,
or not, placing therein a suitable core 10, or by attaching to the edges of said card
tubular or cylindrical strips of suitable material. By the use of these rounded
bearings the date-strip will be smoothly guided around and have frictionless bearing
upon the hanger-card.
The date strip is formed with a series of thirteen date-columns 12 within which
is arranged a series of date numerals so disposed that as said date-strip is turned
on the hanger-card to bring a line of seven of said date columus under the names
of the days of the week each series of said seven columns will present not less
than thirty-one day dates.
The object of this invention being to produce a calendar which shall be perpetual
in its character and yet have the general appearance of and be used in lieu of the
ordinary wall or hanging calendars whose life does not extend beyond one year,
and as the first day of the several months falls upon variable days of the week it
becomes necessary to duplicate a portion of the numerals on the euilless and slidable
date strip. In order to provide for the proper disposition of day dates under all
circumstances and with the least possible employment of dates the said dates are
thus arranged on the date-strip, riz. In the top horizontal line six blank squares
are left at the left hand, the numerals on this line running from 1 to 7 inclusive;
on the second line from the top the numerals run from 2 to 14: on the third line
from 9 to 21 on the fourth line from 16 to 28; on the fifth line from 23 to 31 with
fur blank spaces on the right lind, and on the sixth horizontal line from 30 to 31
inclusive. Innsmuch as, in turning the date strip around the side edges and across
the face of the date enrd so as to bring the date numeral under the name of the
day on which the particular month commences it will sometimes happen that more
date-terminals are exposed to view than there are days in the month, or a dupli-
cation of the day dates are visible, it is necessary to provide some means whereby
such redundant dates may be covered. This is accomplished in a very simple yet
an entirely effective manner by the employment of an endless strip of suitable
pliable material 13 which surrounds and slides across the face of the date-strip 11.
This supplemental date covering strip 13 has on its face a series of blank columns
or squares which register with the adjacent columns and squares on the date strip
but in lieu of continuing the operative horizontal lines of squares 14, 15 the full
length of the strip the upper line 14 consisting of but four squares terminates in
an inner shoulder 16 while the horizontal line of squares 15 next below the line 14
consists of but eleven squares and terminates in an inner shoulder 17. It will this
be seen that these shoulders 16, 17 are separated from each other the distance of
one square apart vertically and seven squares apart, horizontally. These two
lines 14, 15 are in the same horizontal plane ns, and, as said strip 13 is turned,
travel along and across the two lower date lines of the date strip. It will be
apparent that when the date-strip has been turned to bring the appropriate
numerals under and in proper registry with the day Dames by turning the supple
mental strip 13 the stepped lines 14, 15 can be readily brought over the redundant
date numerals on either or both of the lower lines on the date-strip.
18 represents knobs, buttons or equivalent devices attached in any suitable
manner to the rear of said strips 11, 13 to facilitate the movement thereof.
