. I, JEAN BAPTISTE DUBREUIL, of Paris, Rue du Faubourg, Saint Denis,
No. 108, Gentleman, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN CARTS, WAGGONS, AND OTHER VEHICLES," to be as follows:-
This Invention consists in so constructing carts and other similar vehicles
as to enable them to weigh their contents when necessary. The following is an
example of the means by which this Invention may be effected-I form a
skeleton framework or under framing on which rests loosely the body of the
cart or waggon. To said under framing I adapt a V-shaped lever, or two levers,
each bent outwards at their outer ends, which are formed forked, said forked
parts resting each upon a knife edge piece of metal fixed to the under framing
aforesaid, the inner ends of the arms of the said V-shaped lever have a piece of
metal affixed thereto, the upper side whereof is formed with a knife edge, and
the under side thereof is concave, and this concave part is acted upon by the knife
edge of another piece of metal constructed and arranged as follows:-To the
side of the under framing aforesaid and at a short distance from the centre thereof
an upright piece of metal is fixed, same being formed forked at top to receive
the fulcrum of a steel yard or graduated lever. This lever has an arm formed
thereon which descends to the under side of the under framing aforesaid, at-
which point it is bent. This arm carries at or near its end a knife. edge,
which comes underneath the concave surface before mentioned. The upper
edge of the bent forked parts of the aforesaid V-shaped lever are each formed

page_text: with a knife edge corresponding to concave-shaped pieces of metal fixed to
the under side of the body of the cart or waggon, and another concave piece
is placed opposite to the knife edge situate at the inner ends of said V-shape
lever as before stated at a considerable distance from the fulcrum of the steel-
yard lever before mentioned, and to the outside of the aforesaid under framing
I fix a standard, into the upper end of which a metal point is fixed. I also
fix a similar pointed piece of metal on the long arm of the steel yard, and'
adjust sliding weights thereon.. A weight is adjusted on the short horizontal
arm of the steel-yard lever aforesaid, said weight balancing the weight of the
body of the cart or waggon. When empty, said body fits loosely upon the
under framing which supports same, so that supposing said body to have
goods placed therein, the weight of said goods may be ascertained by sliding the
smaller weights on the long arm of the steel-yard lever aforesaid until the points
before referred to come opposite to each other, the body of the cart or waggon
being lifted by the knife edges on the V-shaped lever before mentioned.
Another mode of weighing the contents of carts and waggons intended to
be used on railways consists in mounting the body thereof on four rollers and
moving said body either backwards or forwards by means of a wheel and axle
pinion and rack. When out of use the rollers aforesaid lie on the rails of the
line of railway and when the body of the cart or waggon is moved either back-
wards or forwards, the rollers aforesaid reach to pieces corresponding to levers
connected to a steel yard and thus cause same to indicate the weight of the
contents of the cart or waggon.
