SPECIFICATION in pursuance of the conditions-of the Letters Patent, filed
by the said Edward Dowling in the Great Seal Patent Office on the 3
2nd June 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
DOWLING, of Little Queen Street, in the County of Middlesex, Scale Maker,
send greeting.
WHEREAS Her most. Excellent-Majesty Queen Victoria,-by-Her-Letters-3
Patent, bearing date the Second day of December, in the year of our Lord

page_text: One thousand eight hundred and fifty-four, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Edward Dowling, Her special licence that I, the said Edward Dowling,
my executors, administrators, and assigns, or such others as I, the said Edward
Dowling, 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 "IMPROVEMENTS IN WEIGHING
MACHINES, AND IN THEIR APPLICATION TO IMPLEMENTS OF TRANSPORT," upon the
condition (amongst others) that I, the said Edward Dowling, by an instrument
in writing under my hand and seal, 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 Edward Dowling, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, reference being had to the Sheet of Drawings hereunto annexed,
and to the letters and figures marked thereon (that is to say) :-
My improvements in weighing machines, and in their application to imple-
ments of transport, consists in so constructing them as to be extremely portable,
and at the same time combined with an implement or machine which may be
used for its ordinary purposes with or without the weighing machine attached.
The implement with which I combine the lever weighing machine or steelyard
is the ordinary sack barrow, by which means a considerable weight of goods
may be weighed without the necessity of carrying any large amount of counter-
balance weights, the several parts of the machine being so constructed as to
collapse or fold up to permit the barrow to be used for its ordinary purpose, or
it may be altogether removed from the barrow. I suspend the fulcrum of the
steelyard by two supports from the upper cross bar of the barrow, and suspend
the frame of the goods scale in front of the barrow, with the scale pan or
plate a little above the iron shoe.
The levers are in duplicate, one on either side, inside the side frames of
the barrow and outside the supports of the fulcrum, which is a bar stretched
between the two levers. The long end of the levers project out at the back
part of the sack barrow, and are united at the extreme end, so as to form a
rectangular frame. Two separate rods. of equal length are placed parallel to

page_text: and between the main frame or levers, on which the weights, are placed. These
rods are graduated from the fulcrum in the ordinary manner of a steelyard;
the one carrying the heavier weight indicating quarters or other denominations
of weight, while the smaller weight, which has a traverse of the same extent;
indicates the intermediate amounts. In collapsing, the goods.scale folds up in
front, while the long end of the lever folds down at the back of the barrow,
and by reason of the disposition of the supports of the fulcrum, the levers and
suspending rods are allowed to. fold within the limits, and to be flush with
the side rails of the barrow. The goods scale, which is suspended by a
rectangular frame, has suitable stops on which to rest the weight of goods, and
is properly connected to maintain the necessary freedom of motion. A folding
bracket piece is attached to the side of the barrow at the back,.,which bracket
is placed in position to limit the up and down movement of the tail or, long
end of the lever in weighing, and is also applicable for, holding the machine in
the collapsed position. The fulcrum bar and other parts of the machine. is
suspended, so that the whole may be easily removed from the, barrow, which
may then be, used without the encumbrance....

weighing; Fig. 3.a front view, Fig. 4a side-view, and Fig. 5.a. back view,
of the barrow with the weighing machine-in-a-collapsed state, aa, are the
side rails or frames of the barrow,, which, with the ordinary, shoe-iron b, and
wheels.c, c, require no particular description. I dispense with any intermediate
cross bars between the side frames a, a, connecting them merely by 'the
bottom rail d'and axlete, and at the upper part by the cross rail f: I suspend
the steelyard h, h, by means of two fixed-hooks-gg, in which the fulcruma, x,
of the steelyard rests. A, A; is a wrought or cast iron frame, the backs ribs
ii, of which are received between the side rails a, a, of the barrow, while the
front plate projects, so as to cover those: side rails, and prevent the sack
resting against them... is a plate, on which the sack or other form of goods-is
placed while being weighed, which plate is, pivoted at 1, so as to hold up' in
front when not required for weighing, as seen at Figs. 3. and:4..
ما
The steelyard h, h, I make with a leverage of about the ordinary propor-
tions, but construct it with a double arm or frame 1,2, as seen, in, the back
view, Fig. 5. The short end of the, lever has pivots 4, 5, on which the front
A, A, hangs by its, ribs, i; which, while the machine is in the position shown
at Figs. 1 and 2, keep, the frame. A, A, clear of the barrow frame,, and, free
to move up and down. In order to keep the frame A clear of the barrow at
the lower part, and free to move vertically, Lemploy two hooks, m; which

page_text: take on: two rollers: fitted on a cross stay p of the frame A These
hooks are pivoted at q, q, in order to be thrown back, as seen, in dotted lines
in Fig. 2, when the weighing machine is out of use. The sack frame A being
thus fitted, moves with great freedom and little friction during the operation of
weighing, goods, and may therefore be done with-equal, accuracy as if by a
separate and independant steelyard
In order to sustain the steelyard or weighing lever h; h in the horizontal
position, I pivot a light iron frame rats, s, which may be raised up and -
supported by a stay t, which has a hole u for the reception of pin von the side
framer, To the extreme end of the steelyard I hang the ball B, which
is arranged to be of, a weight according to the weight of goods to be weighed;
thus; supposing the weight of a sack of coals or other materials- to be two
hundredweight, this weight may be made -to counterbalance a weight some-
what less; while the additional and exact weight is determined by the sliding
weight C, which is moved further from or nearer to the fulcrum, its position
being marked by the graduated rod w, on which it slides, the rod w being
graduated to indicate the smaller; subdivisions of weight, such as pounds and
ounces, and, as well understood, in the ordinary steelyard or. lever weighing
machine.
e
Instead of the simple weight B at the end of the lever, that may be repre-
sented bya, number of smaller, weights, which can be changed or varied,
according.to; the weight of goods to be determined. Instead of the ball B
being less in tits, counterbalance than the proper weight of the sack, it may
form the exact counterbalance, and denote the equipoise at once; the excess of
weight in the sack, if any, being, ascertained and determined by the sliding
weight C, as well, understood..
When this sack barrow is employed; for occasional weighing and transporting
goods, the steelyard may be readily collapsed, after removing the weights
B and C, the steelyard being lowered and folded within the limits of the
barrow frame, as shown in Figs. 3, 4, and 5, in which position it is held by the
stay or bar t, which is placed across the back, and hooks into the opposite side
rail at z, retaining the whole firmly in the collapsed position. Folding down
the steelyard has the effect of bringing the front plate A close up to the
barrow frame, and at the same time turning-the-steelyard-off-its-centres-or-
fulcra, in order to prevent injury thereto during the transport of the sack on
the barrow. The hooks m, m, are also thrown back at the bottom, and the
lower part of the frame A, A, fastened close back to the barrow frame by
hooks yy The whole-apparatus.may now be used for the ordinary purposes
of a sack barrow. The iron shoe is made somewhat larger in this machine

page_text: than in the regular sack barrow, in order to form a base, on which the machine
stands while weighing. When the barrow is not required for weighing
purposes, the weighing machine may be readily removed from the barrow alto-
gether by simply disengaging the fastenings t and y, and lifting the fulcra.or
centres x, x, out of the suspending hooks or bearings g, g, when the barrow
may be employed for the transport of sacks or other goods without it. It will
be obvious that the weighing machine may be again readily placed on its
centres and placed in position for weighing when required. Fig. 6 represents
another arrangement and improvement in the steelyard weighing machine for
this purpose, which consists in employing two separate graduated rods E, F,
on which to suspend two moveable weights G, H, the weight H being used
instead of the weight B, before mentioned. The rod F, on which the weight
His suspended, is graduated to show the larger divisions of weight, such as
hundredweights and quarters, while the rod E of weight G is graduated to
show the smaller subdivisions, as pounds and ounces, as before mentioned
with reference to the small weight C. By combining the use of the steelyard
or lever weighing machine with the sack barrow, a very small amount of
weight only is required to be carried about with the machine, and the whole
is readily portable and convenient for use.
Having described the nature of my Invention, and the manner of carrying
the same into effect, I would have it understood that I do not confine myself
to the precise detail herein shown, so long as the combination of the steelyard
or lever weighing machine-with the sack barrow be retained, which I claim-as-
of my Invention..
I further claim the improvement in the steelyard machine, consisting in the
use of two graduated rods and weights, as described with reference to Fig. 6.
In witness whereof, I, the said Edward Dowling, have hereunto set my.
' hand and seal, this Second day of June, in the year of our Lord One
