PROVISIONAL SPECIFICATION left by the said George Henry Toovey
Hawley at the Office of the Commissioners of Patents on the 5th March
1883.
GEORGE HENRY, TOOVEY HAWLEY of Bromley in the County of Kent Gentleman
A NEW OR IMPROVED DATE INDICATOR
•
This Invention relates to a new or improved date indicator and has for its object
to enable a person to calculate almost instantaneously the number of days for
which interest has to be charged upon a bill of exchange or other negotiable
instrument when tendered for discount.
To carry out my invention I proceed as follows:-I make a casing or framing
of metal wood or other suitable material and of any convenient shape.
Such casing or framing is furnished in front with two vertical openings and
across the top of the right hand of such openings a division bar is inserted so as to
form a separate aperture therein to be used as presently described.
Preferably these openings are glazed in order to exclude the dirt.
The casing or framing is divided internally into two compartments either by a
division plate or plates or some equivalent device.
Such division plate or plates or other equivalent device also serve as a bearing
or bearings to carry the inner ends of two horizontal spindles which are mounted
in the left compartment.
The outer ends of such spindles pass through suitable apertures formed in the
left side of the casing or framing for that purpose and project thereout a sufficient
distance to allow of their being rotated either backwards or forwards as desired.
Such spindles are provided with suitable guide pieces which serve to hold in
position a scroll of linen or other suitable material working over rollers or stretcher
bars fitted in the casing or framing upon which scroll the names of the months of
the year are inscribed in their proper rotation for a period extending over

page_text: 18 months that is to say for instance commencing with January and terminating
with July.
The months so inscribed on the scroll successively appear as the spindles are
rotated and are visible through the left opening in the front of the casing
opposite which they are mounted.
In the right compartment two vertical spindles are fitted their lower ends fitting
into and working in suitable socket holes which may be formed either in the base
plate of the casing or framing itself or in a cross bar fitted therein.
Mounted upon these vertical spindles is a scroll of linen or other suitable
material whereon are inscribed seriatim in a horizontal line at the top the figures
representing the days in each month, while a second series of figures placed
immediately below represent the months of the year in their numerical succession.
Placed underneath these two lines of figures are a series of figures arranged in
horizontal lines representing the number of days which have to elapse between
the date when a bill or other instrument is presented for discount and the end of
the month immediately preceding the date when such bill actually matures:-
Thus, for instance, if a bill drawn at 3 months on the 2nd of March and maturing
on the 5th of June following is presented for discount on the 10th of April it is only
necessary to turn one of the horizontal spindles until the month shows April at
the top of the left opening; then turn one of the vertical spindles until the day of
the month on which the calculation is to be made from appears in the right hand
top aperture formed by the division bar placed across the top of the right hand
opening as before mentioned. This being done, then look for the number of days
opposite the month of May which will be 51 that being the number of days from
the 10th of April to the 31 of May and then add on the 5 days in June and you
get 56 which is the number of days for which interest is required to be calculated
Such vertical spindles are of a sufficient length to project sufficiently above the
top plate of the casing or framing to allow of their being manipulated to and fro as
desired while to insure the scroll remaining properly and truly adjusted suitable
rollers or their equivalents are fitted at the back of the right hand opening in the
front of the casing over which the scroll works as such vertical spindles are
rotated either backwards or forwards.
In order to assist the eye the division piece between the two openings in the
front of the casing is marked with suitable guide lines which conduct the eye from
the names of the months to the figures which represent the number of days which
have to elapse between the date of calculation and the termination of the month
immediately preceding the maturing of the bill or other instrument.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said George Henry Toovey Hawley in the Great Seal Patent Office
on the 5th September 1883.
GEORGE HENRY TOOVEY HAWLEY of Bromley in the County of Kent Gentleman.
A NEW OR IMPROVED DATE INDICATOR
"
This Invention relates to a new or improved date indicator or calculating
apparatus and has for its object to enable a person to read ly calculate the number
of days for which interest has to be charged upon a bill of exchange or other
negotiable instrument when tendered for discount
To carry out my invention I proceed as follows:-I make an outer casing a
having a fixed or shifting back board b and face plate c provided with two
vertical openings, or spaces d-d' intersected by horizontal division lines.
Such casing is fitted internally with a framing consisting of one or two
uprights e and two cross bars f placed one at top and one at bottom and furnished
with blocks or bearers g which carry the inner ends of two horizontal spindles h
(hereafter termed "tape rollers")-the outer ends whereof project through the
left side of the outer casing and are furnished with knobs i whereby they can be
rotated
Mounted on these rollers is a date tape ; whereon the names of the months are
inscribed in proper rotation for a period extending over thirteen-eighteen or any
other convenient number of months which names successively appear as the date
rollers are rotated and are visible through the opening or space d while the tape is
kept flat when working over the date rollers by a stretcher plate k mounted on
the cross bars f
These latter are provided with suitable socket holes whereon two vertical
spindles (hereafter termed "figure rollers") work;-the upper ends whereof
project through the top of the outer casing and are furnished with knobs ľ
whereby the figure rollers are rotated
Mounted upon these figure rollers is a scroll (hereafter termed the "figure
scroll") whereon appear a series of nine horizontal lines of figures which are sub-
divided into 357, vertical columns The figures in the first lines shew the days of
the months seriatim horizontally while those in the second line shew the months
of the year placed in similar order
The remaining seven lines consist of a series of groups of figures each group
indicating the number of days that have to run between the date when a bill or
other negotiable instrument is presented for discount (which is shewn by the
figure in the top line) and the end of the month immediately preceding the date
when such bill matures unless such bill matures on the last day of the month-
When the figure rollers are rotated the day and month required together with the
column of figures shewing the number of days the bill has to run appear in the
opening or space d' In order to ensure such Figure scroll working smoothly and
keeping flat it travels over two guide wires n mounted upon the cross bars f one
on each side of a stretcher plate o also mounted on such cross bars.
The operation of this improved indicator or calculating apparatus is as follows:-
Turn the tape rollers h until the current month is visible in the top division of
the opening d-Then turn the figure rollers until the day of the month required
appears in the top division of the opening a while below is seen the column of
figures corresponding thereto and select therefrom that group of figures which
shews the time the bill has to run before it matures-For example: Suppose a bill
drawn on 3rd December at four months and maturing on 6th April following to be

page_text: presented for discount on the 1* January-To find the period for which discount
has to be charged select that group of figures which shews the number of days up
to the end of March the month immediately preceding that in which the bill
matures; this will shew 89 to which number mentally add on six for the
additional days between 31 March and 6th April-the date when the bill matures
This will make 95 thus shewing that the period for which discount is to be
charged is 95 days

Figure 1. of the accompanying drawing shews a view in front elevation of my
improved Calculator with the face plate removed
Figure 2. shews a detail view of such face plate-and
Figure 3. shews a view in front elevation of the apparatus complete-Similar
letters of reference indicate corresponding parts
Having thus particularly described the nature construction and operation of my
said improved apparatus I would have it understood that I do not confine myself
to the exact details of construction hereinbefore described as the same may be
varied without departing from the principle of my invention What I claim as
novel and of my invention is as follows viz
A Date Indicator or Calculating Apparatus consisting of a tape and Figure
Scroll or their equivalents both inscribed in the manner herein before described and
mounted on and actuated by horizontal and vertical rollers working in suitable
bearings furnished with guides and stretchers and fitted in an outer case provided
with a fixed or movable back board and face plate all substantially as hereinbefore
described and shewn
In Witness whereof I the said George Henry Toovey Hawley have hereunto
set my hand and seal this fifth day of September in the Year of Our Lord One
thousand eight hundred and eighty three.
