page_text: LETTERS PATENT to Jean Marie Hospice Auguste Taurines, of Paris,
in the French Empire, Constructor, for the Invention of "IMPROVED
MODES OF CONSTRUCTING BALANCES, WEIGHBRIDGES, AND OTHER WEIGHING
MACHINES."
Sealed the 13th June 1862, and dated the 18th December 1861.
PROVISIONAL SPECIFICATION left by the said Jean Marie Hospice
Auguste Taurines at the Office of the Commissioners of Patents, with his
Petition, on the 18th December 1861.
I, JEAN MARIE HOSPICE AUGUSTE TAURINES, of Paris, in the French Empire,
Constructor, do hereby declare the nature of the said Invention for "IMPROVED
MODES OF CONSTRUCTING BALANCES, WEIGHBRIDGES, AND OTHER WEIGHING
MACHINES," to be as follows:-
My Invention will be best understood by reference to the accompanying
Drawings. Nos. 1, 2, 3, 4, and 5, are sections, taken through the corres-
ponding lines in Figure 1, of a weighing machine. A, B, A', B', are longi-
tudinal iron pieces, and 0, 0¹, are cross pieces, forming a frame for the
machine, supported by a wooden frame or by a foot connected to each angle
of the frame; C, C³, are vertical springs fixed to the cross pieces O, O'. On
that side shown at No. 1, Figures 1 and 2, the lower ends of these springs
are connected with the arms of a lever P, shown at Figures 1, 2, and 6. The

page_text: arms of this lever receive at their upper part two springs D, D¹, parallel to
the first springs, and carrying at bottom a cross piece L, as shown in the
section No. 2, the ends of which serve as supports for the table of the machine
through the medium of the stays T, T¹, united at top by pieces U, U¹, which are
prolonged to V, V₁, somewhat beyond the middle of the machine, as shown in
Figures 2 and 8. On the side No. 5 the lower ends of the springs C, C', are
united to the arms of a second lever G, below the first, as seen in Figures 1, 2,
and 7. To the ends S, S¹, of these arms the springs D, D', section No. 4,
are attached; these springs D, D', carry at bottom a cross piece with supports
for the table as in the section No. 2. In the middle of the frame the two
levers are united through bolts, by two vertical springs H, H¹, a platform is
laid on the supports to receive the load. Figure A, drawn in red and black
ink, illustrates the action of the springs. The springs C, C¹, and D, D', and
the springs H, HI¹, in the centre, when under the action of a load, assume the
positions C M, C¹ M, N N¹, H" H". The end of the lever P has to move
vertically, and for this purpose, when the machine is not at work, it lies above
the level of the lower ends of the springs C, C¹, to an extent equal to half
the length of one of them plus the half of the descent that it makes under
the maximum load.
To construct a weighing machine with a dial plate, the end of the lever P
is connected to a vertical rod furnished with a rack, which through the agency
of a pinion takes the needle of the dial plate over or round the scale.
For a steelyard I adopt the arrangement first described and apply to the
end of a lever P a vertical rod to connect it thereto.
For weighing machines or bridges fitted with a dial plate and steelyard
I employ similar springs to those before described.
When it is necessary that the indicating mechanism be placed laterally, the
centre springs are modified in the following manner, and as shown at Figure 9,
as well as by the sections Nos, 1 bis, 2 bis, 3 bis, which correspond with the sectional
lines 1bis, 2 bis, and 3 bis, of Figure 9; see also Figures 10 and 11 of the steel-
yard arrangement. The levers P and G, connected to the springs, are both
of the shape of the lower lever G, with this difference, that they terminate in
the centre, one on a forked piece a, b, section No. 2bis, and the other in the
pieces c, d. To each of these levers springs H, H', are fixed, and the four
springs are in the same plane and are united at top, as seen in the section
No. 1bis, in a cross piece e, f, g, h. The two other arms of this piece carry
two springs i, j, fixed at the bottom, see section No. 3bis, to a lever k, the
short arm of which receives two springs, not parallel to the preceding, and
which are inserted at top in fixed pieces. The extremity of the long arm of

mechanism, the needle over the dial for indicating the weight. In applying
the steelyard to my method of constructing weigh-bridges the arrangements
just described are the same as those shown at Figures 10 and 11, with this
difference, that the long lever of the transmission springs is placed above, and
that these springs act by tension, while those in the middle, in the preceding
example, act by compression.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jean Marie Hospice Auguste Taurines in the Great Seal
Patent Office on the 18th June 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JEAN
MARIE HOSPICE AUGUSTE TAURINES, of Paris, in the French Empire,
Constructor, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of December, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Jean Marie Hospice Auguste Taurines, Her special licence that I, the
said Jean Marie Hospice Auguste Taurines, my executors, administrators, and
assigns, or such others as I, the said Jean Marie Hospice Auguste Taurines,
my executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVED MODES OF CONSTRUCTING
BALANCES, WEIGHBRIDGES, AND OTHER WEIGHING MACHINES," upon the condition
(amongst others) that I, the said Jean Marie Hospice Auguste Taurines, my
executors or administrators, by an instrument in writing under my, or their,
or one of their hands and seals, should particularly describe and ascertain
the nature of the said. Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Jean Marie Hospice Auguste Taurines,
do hereby declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and

page_text: by the following statement thereof, reference being had to the Drawings
hereunto annexed, that is to say:-
My Invention will be best understood by reference to the accompanying
Drawings. Nos. 1, 2. 3, 4, and 5, are sections, taken through the corre-
sponding lines in Figure 1, of a weighing machine. A, B, A¹, B', are longi-
tudinal iron pieces, and O, O¹, are cross pieces, shown in the sections Nos. 1
and 5, forming a frame for the machine, supported by a wooden frame or by a
foot connected to each angle of the frame; C, C¹, are vertical springs fixed to
the cross pieces 0, 0¹. On that side shown at No. 1 the lower ends of these
springs are connected with the arms of a lever P, shown at Figures 1, 2, and 6.
The arms of this lever receive at their upper part two springs D, D', parallel
to the first springs, and carrying at bottom a cross piece L, as shewn in the
section No. 2, the ends of which serve as supports for the table of the machine
through the medium of the stays T, T¹, united at top by pieces U, U', which
are prolonged to V, V¹, somewhat beyond the middle of the machine, as shewn
in Figures 2 and 8. On the side No. 5 the lower ends of the springs C, C¹,
are united to the arms of a second lever G below the first as seen in Figures
1, 2, and 7. To the ends S, S¹, of these arms the springs D, D¹, section No. 4,
are attached; these springs D, D¹, carry at bottom a cross piece with supports
for the table, as in the section No. 2. In the middle of the frame the two
levers are united, through bolts, by two
laid on the supports to receive the load.

the springs H, H, in the centre, when under the action of a load, assume the
positions C M, C¹ M³, N N¹, H" H. The end of the lever P has to move
vertically, and for this purpose, when the machine is not at work, it lies above
the level of the lower ends of the springs C, C', to an extent equal to half the
length of one of them, plus the half of the descent that it makes under the
maximum load.

To construct a weighing machine with a dial plate, the end of the lever P is
connected to a vertical rod furnished with a rack, which through the agency
of a pinion takes the needle of the dial plate over or round the scale.
For a steelyard, I adopt the arrangement first described and apply to the
end of the lever P a vertical rod to connect it thereto.
For weighing machines or bridges fitted with a dial plate and steelyard
I employ similar springs to those before described.
When it is necessary that the indicating mechanism be placed laterally the
centre springs are modified in the following manner, and as shown at Figure 9,
as well as by the sections Nos. 1 bis, 2 bis; 3bis, which correspond with the sectional

page_text: lines 1, 2, and 3bis, of Figure 9; see also Figures 10 and 11 for the steel-
yard arrangement. The levers P and G, connected to the springs, are both
of the shape of the lower lever G, with this difference, that they terminate in
the centre, one in a forked piece a, b, section No. 2bts, and the other in the
pieces c, d. To each of these levers springs H, H', are fixed, and the four
springs are in the same plane and are united at top, as seen in the section
No. 1bis, in a cross piece e, f, g, h. The two other arms of this piece carry
two springs i, j, fixed at the bottom, see section No. 3bis, to a lever k, the
short arm of which receives two springs m, n, parallel to the preceding, and
which are inserted at top in fixed pieces. The extremity of the long arm of
the lever works, by means of a vertical rod, by toothed gearing or other
mechanism, the needle over the dial for indicating the weight. In applying
the steelyard to my method of constructing weighbridges the arrangements
just described are the same as those shown at Figures 10 and 11, with this
difference, that the long lever of the transmission springs is placed above, and.
that these springs act by tension, while those in the middle in the preceding
example act by compression.
Figure B illustrates in diagram my Invention applied to measuring power
by the angle of defection. First, A, A¹, are springs united by the cross pieces
A', B', to which the lever giving the deflection angle is attached. Second,
A, A', and D, D', are springs united by the cross piece A', D', to which the
lever is attached. The spring A, A¹, acts as in the previous arrangement;
but the second D, D', receives a certain amount of pressure applied at D.
Third, C, C, and B, B', are springs united by the cross piece C¹, B', to which
the lever is attached. The first spring C, C¹, is submitted to a certain amount
of pressure, having C for a fixed point. The second spring B, B', acts as in
the first case. Fourth, C, C¹, and D, D¹, are springs united by the cross
piece C, D, coupled with the lever. The spring C, C', works as in the third
case; and the spring D, D¹, as in the second. It will be remarked that the
springs A, A, and B, B¹, receive tension, and the springs C, C, D, D', com-
pression. A or C is the fixed point of the joint, and B or D the point at
which the power is applied. In these different cases the deflection angle is
calculated in the same way with a sufficient approximation. When the end
of the second spring is free I keep it in the same direction by means of a sort
of elastic slide, shown in the Diagram Figure C; it is composed of two
springs a, a, b, b, parallel to one another, being divided from one another
the distance, say, from a to b, equal to about half or a little less of their length.
The ends a and b are inserted in a fixed piece, while the two others a', 6', are
free to move, as shewn by the red ink lines, and are in connection with the

page_text: extremity of the second coupling spring, which acts as a point for the appli-
cation of the power; the coupling springs are perpendicular to those in the
slide. During the action of the slide the two springs bend, as shown, while
the line a¹, b', always preserves the same direction.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim,-
First, the general arrangement and method of constructing balance and
weighbridges with elastic or spring-like connections, substantially in manner
herein-before described and illustrated in the accompanying Drawings.
Second, the employment of suspension springs in pairs, in manner and for
the purposes herein-before described and illustrated in the accompanying
Drawings.
Third, the employment of central springs (marked H) for the purpose of
enabling the platform to be loaded at any part for increasing its strength and
acting as a regulator, all as herein-before described and illustrated in the
accompanying Drawings.
Fourth, the employment of a lever (marked P), the end of which is free to
move in a vertical direction, substantially in manner and for the purposes
herein-before described and illustrated in the accompanying Drawings.
Fifth, measuring the power of weighing machines, dynanometers, and other
instruments by means of springs coupled together and submitted to tension, or
by the angle of deflection of the said springs, as herein-before described.
In witness whereof, I, the said Jean Marie Hospice Auguste Taurines,
have hereunto set my hand and seal, this Twenty-sixth day of May,
One thousand eight hundred and sixty-two.
