I, WILLIAM WOOD, of Richmond in the county of Fort Bend and State of Texas
United States of America, Mechanic, do hereby declare the nature of this invention
to be as follows :-
This my invention relates to time-calculators; and has for its object to provide a
simple, inexpensive, and durable machine whereby the aggregate number of days from
any one date to another within the space of one year may be accurately and
expeditiously ascertained; and it consists of the parts and combination of parts
hereinafter described.
The
I provide a frame, the body of which in this instance is of wood; but it may be of
any suitable material; and I also provide metal strips, secured to the side edges of
the aforesaid body by screws or nails, when said body is of wood, and if metal, they
may be formed integral therewith or secured thereto in any desired manner.
upper edges of the metal strips are bent or lapped at right angles to their bodies to
form flanges. or lips, beneath which flanges the edges of the calendar and a pane of
glass, are inserted and held in place.
I provide two metallic receptacles or holders for the time-table. These holders are
semi-cylindrical in cross-section, and one side extends down to and slightly beyond the
upper surface of the aforesaid body, to which they are loosely or pivotally attached
at each end by means of screws passing through lugs, which project from said holders,
so that they may be turned or thrown up when it it desired to remove the glass or
gain access to the calander and time table. Spring-metal catches are secured to each
end of the body and engage projections on suitable holders to hold the same securely
in place. The opposite sides, of the holders are shorter and have their edges turned
outward slightly to afford ample room underneath the same for the calendar, glass, etc.;
and permit the easy removal of the same when the holder is raised. At each end the
holders are slotted to receive the axles of suitable rollers which carry the time-tables,
and on the inner sides of the end boxes are formed, either integral with said ends or
soldered or brazed thereto, said boxes being slotted to correspond with the slots in the
רנ...D

page_text: ends. In each of these boxes a spiral spring, is inserted so that its end will bear
against the axle outside one of the rollers, a metal washer, being interposed between
said rollers and boxes to lessen the friction.
To the aforesaid rollers, which are formed, preferably, of compressed paper, the
ends of the time-table are secured in any desired manner, so that it may be wound
or unwound on said rollers when the buttons on the ends of axles are turned.
The time-table works between the calendar and a sheet of paper, card-board, or any
other suitable material, the side edges of the time-table and calendar being secured to
a strip of paper or other material, interposed between them, but having their end edges
free, so that the time table may work easily between them."
The calendar has five slits or openings, formed therein at equal distances apart and
extending nearly its entire length, through which the numbers on the time-table
beneath may be readily seen, and along the sides of these openings are printed or
otherwise marked the names of the several months of the year from January to
December, both inclusive, beginning with January at the upper left-hand corner of
the calendar and ending with December at the lower right-hand corner. Opposite the
names of the months the number of days contained in each are printed in rotation,
the first column containing the whole number of days in January and February and
the first fourteen days of March, seventy-three days in all, and each of the other
columns containing a like number seventy-three.
Referring again to the time-table, which may be of any desired flexible material—such
as paper, either plain or lined with muslin or cloth or silk-ten columns or rows of figures
are printed or marked thereon, the rows on the left-hand side of each column being in
black ink and those on the right-hand side in red ink, preferably; but they may be of
other colours, if desired, black and red being preferred simply because of the great
contrast between them; or only one colour may be used, in which case one row will
be printed in heavier type, so as to better distinguish between them.
The first column on the left hand side begins with the character or cipher 0. Then
follows the number 364, then 363, and so on down in regular rotation until the
numeral one (1) is reached, when another cipher 0 is printed, and then 364, and so
on down to 293, when the first column ends, there being in all four hundred and
thirty-six numbers and two ciphers in this column. The second column begins
with 292 and runs to the numeral one, (1,) then a cipher, and then 364, and so on,
each of the left-hand columns in the four (including the second) remaining columns
containing four hundred and thirty-seven numbers and one cipher. The first row in
the right-hand column contains four hundred and thirty-six numbers and two ciphers,
the ciphers being opposite the ciphers above described and the numbers being
reversed that is, they are made to read from top to bottom, beginning with the
numeral one, (1). The second, third, fourth, and fifth rows on the right-hand side
each contain four hundred and thirty-seven numbers and one cipher, no one of which
is higher than three hundred and sixty-four.
To ascertain the number of days between two dates, all that is necessary to be done
is to turn one of the buttons, thus winding the time-table until the ciphers are in the
slit or opening alongside or to the right of the month containing the date from which
it is desired to count are brought opposite that date, when the desired number of days
will be found opposite the other date in the left-hand row, if in the past, and in the
right-hand row if in the future. For example, it being desired to ascertain the number
of days, including the day counted from, between "October 5" and "January 16"
last the ciphers are brought opposite "October 5," and in the left-hand column of
figures opposite "January 16" will be found the aggregate number-that is, 262; if
in the future, the number in the right-hand row opposite will give it-thus, 103. In
the case of leap year one day is added to the aggregate number.

page_text: I, WILLIAM WOOD of Richmond in the county of Fort Bend and State of Texas,
United States of America, Mechanic, 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:-
a.
This my invention relates to time-calculators; and it has for its object to provide
simple, inexpensive, and durable machine whereby the aggregate number of days from
any one date to another within the space of one year may be accurately and expedi-
tiously ascertained; and it consists of the parts and combinations of parts hereinafter
described and claimed.
In the accompanying drawings, forming a part of this specification, Fig. 1 is a plan
view of the device; Fig. 2, a longitudinal section of the same; Fig. 3, a cross-section
on the line xx, Fig. 1; and Fig. 4, a like section on the line Y Y, same figure.
Similar letters refer to similar parts throughout all the views.
A represents the body or back of the frame, which in this instance is of wood; but
it
may be of any suitable material; and B the metal strips, secured to the side edges
of the body A by screws or nails, when said body is of wood, and if metal, they may
be formed integral therewith or secured thereto in any desired manner.
The upper
edges of the metal strips are bent or lapped at right angles to their bodies to form
flanges or lips a, beneath which flanges the edges of the calendar M and a pane of
glass, C, are inserted and held in place.
D represents two metallic receptacles or holders for the time table P. As clearly
shown in Fig. 2. these holders are semi-cylindrical in cross-section, and one side
extends down to and slightly beyond the upper surface of the body A, to which they
are loosely or pivotally attached at each end by means of screws passing through the
lugs b, which project from said holders, so that they may be turned or thrown up
when it is desired to remove the glass C or gain access to the calendar and time-table.
Spring metal catches c are secured to each end of the body A and engage projections d
on the holders D to hold the same securely in place. The opposite sides, e, of the
holders are shorter and have their edges turned outward slightly to afford ample room
underneath the same for the calendar, glass, &c., and permit the easy removal of the
same when the holder is raised, as indicated. by dotted lines in Fig. 2. At each end
the holders are slotted to receive the axles F of the rollers G, which carry the time-
tables, and on the inner sides of the ends boxes E are formed, either integral with
said ends or soldered or brazed thereto, said boxes being slotted to correspond with
the slots in the ends. In each of these boxes a spiral spring, H, is inserted so that its
end will bear against the axle F outside of the roller G, a metal washer, g, being
interposed between said rollers and boxes to lessen the friction.

page_text: To the rollers G, which are formed, preferably, of compressed paper, the ends of the
time-table are secured in any desired manner, so that it may be wound or unwound on
said rollers when the buttons R on the ends of axles F are turned.
The time-table P works between the calendar M. and a sheet of paper, card-board,
or any other suitable material, K, the side edges of the time-table and calendar being
secured to a strip of paper or other material, L, interposed between them, but having
their end edges free, so that the time table may work easily between them.
The calendar M, as clearly shown in Fig. I, has five slits or openings, m, formed
therein at equal distances apart and extending nearly its entire length, through which
the numbers on the time-table beneath may be readily seen, and along the sides of
these openings are printed or otherwise marked the names of the several months of the
year from January to December, both inclusive, beginning with January at the upper
left-hand corner of the calendar and ending with December at the lower right-hand
corner. Opposite the names of the months the number of days contained in each are
printed in rotation, the first column containing the whole number of days in January
and February and the first fourteen days of March, seventy-three days in all, and each
of the other columns containing a like number-seventy-three. In the drawings only
the months of January and October are numbered in full, the others having merely
the first and last days of each month shown.
Referring again to the time-table P, which may be of any desired flexible material-
such as paper, either plain or lined with muslin or cloth or silk-ten columns or rows
of figures are printed or marked thereon, the rows on the left-hand side of each
column being in black ink and those on the right-hand side in red ink preferably;
but they may be of other colours, if desired, black and red being preferred simply
because of the great contrast between them; or only one colour may be used, as in
the drawings, where the rows on the right-hand side are formed on surface shading,
in which case one row will be printed in heavier type, so as to better distinguish
between them.
The first column on the left-hand side begins with the character or cipher 0, (as
shown in the fourth opening.) Then follows the number 364, then 363, and so on
down in regular rotation until the numeral one (1) is reached, when another cipher
is printed, and then 364, and so on down to 293, when the first columns ends, there
being in all four hundred and thirty-six numbers and two ciphers in this column. The
second column begins with 292 and runs to the numeral one, (1,) then a cipher, and
then 364, and so on, each of the left-hand columns in the four (including the second
remaining columns containing four hundred and thirty-seven numbers and one cipher.
The first row in the right-hand column contains four hundred and thirty-six numbers
and two ciphers, the ciphers being opposite the ciphers above described and the
numbers being reversed—that is, they are made to read from top to bottom, beginning
with the numeral one, (1.) The second, third, fourth, and fifth rows on the right-
hand side each contain four hundred and thirty-seven numbers and one cipher, no one
of which is higher than three hundred and sixty-four. In the drawings the top and
bottom numbers which would show with the ciphers in the fourth opening at "October 5"
are only shown, it not being deemed necessary to fill in all the numbers.
To ascertain the number of days between two dates, all that is necessary to be done
is to turn one of the buttons R, thus winding the time-table until the ciphers in the
slit or opening alongside or to the right of the month containing the date from which
it is desired to count are brought opposite that date, when the desired number of days
will be found opposite the other date in the left-hand row, if in the past, and in the
right-hand row if in the future. For example, it being desired to ascertain the
number of days, including the day counted from, between "October 5" and
January 16" last the ciphers are brought opposite "October 5," as in the drawings,
and in the left-hand column of figures opposite "January 16" will be found the
aggregate number-that is, 262; if in the future, the number in the right-hand row
opposite will give it-thus, 103. In the case of leap-year one day is added to the
aggregate number.
