page_text: LETTERS PATENT to Richard Archibald Brooman, of 166, Fleet Street,
in the City of London, Patent Agent, for the Invention of "IMPROVE-
MENTS IN MACHINES FOR WEIGHING AND MEASURING CORN AND OTHER GRAIN."
-A communication from abroad by Joseph Alexandre Augusto Catenot,
of Lyons, France.
Sealed the 11th March 1862, and dated the 13th September 1861.
PROVISIONAL SPECIFICATION left by the said Richard Archibald
Brooman at the Office of the Commissioners of Patents, with his
Petition, on the 13th September 1861.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, Patent Agent, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINES FOR WEIGHING AND MEASURING CORN AND OTHER
GRAIN," (communicated to me from abroad by Joseph Alexandre Auguste
Catenot, of Lyons, France,) to be as follows:-
This Invention will be best understood by reference to the accompanying
Drawing, its object being to weigh, filled sacks by means of a steel-yard
arranged as hereafter described, and to ascertain in any known measure the
quantity the sacks contain.
6 is a weighing platform and frame for supporting the sacks; t is a rod
connecting the levers with a steelyard c. This steelyard is composed of two

page_text: bars c and d. The upper bar c carries a slide f to which a measure i or
weight is hung; the lower bar & carries another slide h, to which a steel
band, shown by the red lines, is attached. This band passes round a pulley e
at each end of the bar, and thus a means is afforded by which the slide h is
drawn along the bar. Each bar carries a scale with the figures in the upper
written from left to right, and in the lower from right to left. is a hopper
hooked on to the frame; o is a frame on which the measure i is placed, to be
filled with grain, where it is held by a small stud r on the measure, which
enters a notch or slot in the arm n; m is a "strike" hinged to the bracket s
for smoothing the surface of the grain; w is the balance at the end of the
steelyard, and p is a stop for securing the steelyard when not in use. To
measure the contents of the sack, it is placed on the platform 6; the measure i
is placed on the frame o below the hopper and filled with grain, the surface
thereof being smoothed by the strike. The filled measure is then hung on to
tho slide on the upper bar of the steelyard, and is drawn to or fro until an
even balance is obtained. The figure on the scale c to which the indicator u
of the slide points represents the number of measures contained in the sack.
To ascertain the weight of a sack a given weight takes the place of the
measure; the weight is drawn along the slide in a similar manner to the
measure until an even balance is obtained, and the figure at which the
indicator u points shows the weight of the sack. The weight of any given
ineasure is obtained by means of the slide h on the lower bar of the steelyard;
this slide is formed in two parts, one fixed and the other movable. The sack
is removed from the platform, the upper slide f is drawn to the first number (in
this case 20) on the indicating scale, the filled measure is hung on at the
point the weight k occupied, and by means of the thumb piece, the movable
part of the slide is moved along the bar d until an even balance is obtained.
The figure to which the front part of this moveable piece points on the lower
bar d is the weight of the measure.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Archibald Brooman in the Great Seal Patent Office
on the 13th March 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, Patent
Agent, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Jer Letters
Patent; bearing date the Thirteenth day of September; 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 Richard Archibald Brooman, IIer special licence that I, the
said Richard Archibald Brooman, my executors, administrators, and assigns,
or such others as I, the said Richard Archibald Brooman, my execu-
tors, 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 "IMPROVEMENTS IN MACHINES FOR WEIGHING AND
MEASURING CORN AND OTHER GRAIN," (communicated to me from abroad by Joseph
Alexandre Auguste Catenot, of Lyons, France,) upon the condition (amongst
others) that I, the said Richard Archibald Brooman, 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 Richard Archibald Brooman, do
hereby declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by
the following statement thereof, reference being bad to the Drawings hereunto
annexed, that is to say:-
This Invention will be best understood by reference to the accompanying
Drawings, it object being to weigh filled sacks by means of a steelyard
arranged as hereafter described, and to ascertain in any known measure the
quantity the sacks contain.
Figure 1 is an end view, and Figure 2 is a side elevation of the machine ;
and Figures 3, 4, 5, 6, and 7, are views of parts in detail.
bis a weighing platform and frame for carrying the corn or grain; t is a rod
connecting the levers with a steelyard c. This steelyard, a detached view of
which is given at Figure 3, is composed of two bars c and d; the upper bar c
carries a slide f; to which a measure i or weight is hung; the lower bar d
carries another slide h, to which a steel band, shewn by the red lines is
attached. This band passes round a pulley e at each end of the bar, and thus

page_text: a means is afforded by which the slide h is drawn along the bar. Each bar carries
a scale with the figures in the upper part written from left to right, and in the
lower part from right to left. 1, Figure 5, is a hopper hooked on to the frame';
o, Figure 4, is a frame on which the measure i is placed to be filled with grain.
It is held by a small stud on the measure, which enters a notch or slot in
the arm n; m is a "strike" hinged to the bracket s, for smoothing the
surface of the grain; w is the balance at the end of the steelyard; and p
is a stop for securing the steelyard when not in use. To measure the contents
of the sack it is placed on the platform b, the measure i is placed on the
frame o below the hopper, and filled with grain, the surfaco thereof being
smoothed by the strike. The filled measure is then hung on to the slide f, on
the upper bar of the steelyard, and is drawn to or fro until an even balance
is obtained. The figure on the scale c, to which the indicator of the slide f
points, represents the number of measures contained in the sack. To ascer-
tain the weight of a sack a given weight takes the place of the measure, the
weight is drawn along the slide in a similar manner to the measure, until an
even balance is obtained, and the figure at which the indicator points shows
the weight of the sack. The weight of any given measure is obtained by means
of the slide h on the lower bar of the steelyard. This slide is formed in two
parts, one fixed and the other movable. The sack is removed from the platform,
the upper slide is drawn to the first number (in this case 20) on the indi-
cating scale, the filled measure is hung on at the point the weight k occupied,
and by means of the thumb pieces the movable part of the slide is moved along
the bar d until an even balance is obtained. The figure to which the front
part of this movable piece points on the lower bar d is the weight of
the measure. The rod t being ten times more powerful than the table b,
it follows that any weight applied to this rod will hold in equilibrium ten
similar weights on the platform. This rod is connected by means of a cap and
knife edge to the rear of the beam of the steelyard, which forms a lever, and on
which an ascertained weight is free to travel. If the weight used upon the
steelyard is, for example, one pound, the weight placed on the platform will
be indicated in pounds, and the same for every other denomination of weight.
In measuring it is necessary to counterbalance or nullify the weight of the
measure, the slide, and the cap running on the steelyard, therefore their weight
is balanced by another weight which acts in a contrary direction, and for this
purpose the traveller or compensator h is used; it is free to slide on the rod d,
and is secured to the steelyard by the steel band passing round rollers e to the
..

unto set my hand and seal, this Thirteenth day of March, One thousand
eight hundred and sixty-two.
