Improvements in Hydrostatic Scales.
I, MIRON WALLACE NEWTON, of Bryant Street College View, Lancaster County,
Nebraska, United States of America, Business Agent, do hereby declare the nature
of my invention, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention relates to improvements in weighing apparatus.
The object of the invention is to produce an accurate weighing apparatus which
will automatically and plainly indicate the weight of any object placed upon
its platform or carrier when the same is within its range or capacity, and to
combine with an ordinary scale beam, a supplemental device for plainly indicating
any weight less than a multiple of the maximum capacity of such supplemental
device.
The invention consists in the combination of a jar or containing vessel for
liquid having a certain coefficient of expansion, whereby the variations in the
density of the liquid arising from changes in temperature may be compensated
by a corresponding variation in the space between the interior of the containing
vessel and the exterior of a float so that as the liquid expands and becomes
lighter, a given movement of the float will cause the liquid to rise higher in
the vessel and thus maintain a constant resistance to the movement of said float.
The invention also consists in the combination of a hydrostatic balance, an
ordinary balance beam and a pointer or indicator.
The invention further consists in the combination of a compensating hydrostatic
balance, an ordinary scale beam and an automatic indicator.
In the drawings,
Fig. 1, is a sectional elevation of an ordinary platform weighing scale, and
Fig. 2, is a plan of the supporting beam, the hydrostatic attachment being in
section.
A is the platform, B, the supporting beam, C the ordinary balance beam, D, a
dial, E, a pointer, and I, a hydrostatic attachment.
The hydrostatic attachment or weight balance F consists of a vessel G for con-
taining the liquid, made of glass or other material having a low coefficient of
expansion, and a float H, of iron or other suitable material having a higher
coefficient of expansion than that of the vessel, and these are so proportioned to
each other and to the mercury or other liquid to be used that the resistance to the
movement of the float will be constant whatever the temperature within the
ordinary limits of the atmosphere. The float is coupled with the balance beam
by means of link ƒ, yoke g and loop h. Pins or knobs ii project from the float
to prevent jamming between the float and the vessel. The arrangement of the
hydrostatic device above the balance beam so as to have a downward pull
Berves to keep the float opposite the center of the liquid and thereby avoids
friction.
My invention embraces in a single apparatus, accurate and convenient means for
indicating any predetermined weight as well as any multiple and fraction thereof.
According to the dial shown in the drawings, the hydrostatic device is intended to
balance any weight from zero to 100 units of weight. When a greater weight is
to be measured, a poise which will balance some multiple of the 100 units will be
adjusted on the hanger c'.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed I declare that what I
claim is :-
1. In a weighing apparatus, the combination of a hydrostatic counterpoise,

float having a higher coefficient of expansion, and an automatic indicator or pointer,
as described.
2. The combination of an automatic compensating hydrostatic counterpoise, an
ordinary balance beam and an automatic indicator, as described.

PROVISIONAL SPECIFICATION.
Improvements in Cheques and other Monetary Documents.
I, MANNING AUGUSTUS DREW, of 69 Park Street, Lynn, Essex County,
State of Massachusetts, United States of America, Advertising Agent, do hereby
declare the nature of this invention to be as follows:-
My invention relates especially to means for preventing alterations in the
amounts indicated on cheques, deposit slips, hotel cheques and the like, after
having been made; and it consists in certain novel features hereinafter fully set
forth the object being to produce a simple, cheap and effective device of this
character.
The nature and operation of the improvement will be readily understood by all
conversant with such matters from the following explanation:
The faces of the improved cheque and stub are imprinted with the name of the
bank, date and amount-spaces, in the ordinary manner.
The cheque is connected with its stub by a sheet, the face of said sheet being
divided by vertical and transverse lines into spaces.
60
Vertical columns are thus formed which are indicated by the words, " units,"
tens,"
," "hundreds," and "thousands," three columns being in the present instance
employed for each denomination.
In the set of three columns denominated thousands, the nine digits are arranged
as follows reading transversely from left to right "3, 2, 1," in the first transverse
line; "6, 5, 4," respectively in the spaces directly below the first three numerals,
and "9, 8, 7," in the third transverse line below the second set of three numerals.
A like arrangement of digits is imprinted in the second three columns denominated
"hundreds," and like arrangements in the third and fourth columns denominated,
respectively, "tens," and "units," each block of digits being arranged vertically
below and at the right of the preceding block so that the series runs diagonally
from the upper left hand corner of the sheet, to the lower right hand corner.
For convenience, at the top of each block of digits, excepting that of the
highest denomination, a zero is imprinted in each of the three vertical columns.
The lines forming the spaces and the line separating the cheque from the sheet,
may be indented or perforated, if desired, to enable said sheet to be more readily
torn on said lines.
The name of the payee and amount payable being filled out on the face of the
cheque-body, and stub, in the ordinary manner, the sheet is torn or cut on the lines,
in such way that the numeral in the lower outer corner of that portion of each
block of numerals which is left on the part of the sheet, attached to the cheque-
body, when read consecutively will indicate the amount for which said cheque is
drawn. For example, if the cheque is drawn for fifteen hundred and forty-eight
dollars and seventy-three cents ($1548.73). The maker in separating the cheque
from the stub cuts the sheet, vertically downward, and laterally in such manner
that the numeral "1" of the block of digits in the thousands column is separated
from the remainder of its block.
The lateral dividing line is continued until it meets the vertical dividing line on
the first column of the hundreds block which is continued downward and the sheet
again cut transversely separating the numeral "5" from its block. The division
is continued separating the numeral "4" in the tens block and "8" in the unit
block thus showing in the lower outer corners of the notches of that portion of
the sheet which remains attached to the body of the cheque, that said cheque has
been drawn for one thousand five hundred and forty-eight dollars ($1548.00).
.

page_text: The corresponding spaces left on that portion of the sheet attached to the stub,
show at once that such numerals have been removed. The stub may be provided
with divisions for indicating cents if desired but it is not deemed essential.
It will be seen that by arranging the digits, as described and the digits in the
corners on the sheet portion remaining attached to the cheque-body, being
employed to indicate the amount, that said amount cannot be "raised" or made
larger by tearing off any of the numerals after the cheque has been separated from
its stub. And that in such case the removal of any numerals from the sheet
portion left on the stub would indicate a larger amount than that for which the
cheque was drawn.
The arrangement of the numerals in each of the blocks may be varied so long
as they read from the largest numeral at the left to the smallest numeral at the
right, and said blocks are arranged diagonally on the sheet, as described.
I find it more convenient, however, to arrange said numerals in squares of three
numerals on a side.
In another form a deposit slip is connected with a duplicate or stub-slip by the
sheet.
In this application of the system the numerals are arranged in each block in
diametrically opposite order from that described for the cheque, the smaller
numerals being disposed in the lower transverse line of each block and reading
in their natural order from left to right.
The total amount indicated on the deposit slip and stub is also shown at a glance
on that portion of the sheet remaining on the deposit slip, in the same manner as
on the cheque.
The reversal of the numerals for use on said deposit slip is for the purpose that,
should any of said numerals be cut from the slip portion of the sheet, after it is
separated from its stub, it will of necessity indicate a larger amount than the face
of said slip thus preventing said amount from being reduced.
The system, as described, may be applied in like manner to cheque for any
purpose, as for use in restaurants, hotels, and similar places, preventing any change
in the cheque after having been separated from its stub and before its return.
Books for use by savings banks and similar institutions may also be prepared
by the same system whereby danger from officials or others entering false amounts
in either the books of the bank or the pass book may be guarded against.
Any number of divisions may be formed on the sheet, to include fractional
parts of amounts; or other symbols may be substituted for the numerals in the
spaces on said sheets.
These sheets may also be interposed between the stubs and certificates of
stock-certificate books to guard against raising and over issues of stock, and
are applicable to pay rolls and for similar uses.
It will be understood that I do not confine myself to connecting the stub to the
cheque by sheet, to the left of said checks, as if deemed necessary for convenience,
it may be attached at either of the other three sides, in which case the diagonal
arrangement of the blocks of numerals would be varied to conform, but the
arrangement of the numerals in said blocks would remain the same in relation to
the stub.
