66, Chancery Lane, in the County of Middlesex, Civil Engineer, for the
Invention of "THE APPLICATION TO CARTS OR OTHER VEHICLES OP APPARATUS
PROVISIONAL SPECIFICATION left, by the said William Edward Newton
at the Office of the Commissioners of Patents, with his Petition, on
the 24th February 1858.
I, WILLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane,
in the County of Middlesex, Civil Engineer, do hereby declare the nature of
the said Invention for "THE APPLICATION TO CARTS OR OTHER VEHICLES OF
APPARATUS FOR WEIGHING THE LOAD, CONTAINED IN SUCH VEHICLES," to be, as
follows:-
This Invention consists in the employment of a system of levers and a
frame applied between the body of a cart or other vehicle and its axle or
axles, and combined with a scale beam or steelyard attached to the body in
such a manner as to weigh the load upon the vehicle. It further consists
in a contrivance for securing the body of the cart firmly to the axles when
the weighing, apparatus is not in use, and for bringing, the cart body and
weighing apparatus into an operative relation, and, when the weighing is to

page_text: be performed. The system of levers by which the weighing is effected does not
interfere with the tilting of the cart to discharge the load, as when the body
is locked to the scale frame, the said scale frame and the whole system of
levers and the cart body are allowed to tilt together when the front of the
cart body is detached from the shafts, the axles turning in the wheels as in
the tilting of a common cart. To permit the weighing operation, however,
the front of the body must not be connected directly to the shafts to prevent
the tilting, as is the case in a common cart, but the connection must be made
by means of the scale frames. A convenient means of connection between
the scale frame and shafts consists of a cranked lever fitted to turn loosely
on the front end of the shaft, and having attached to it two bolts, which are
árranged to slide through corresponding holes in the shafts and in the front
portions of the side pieces of the scale frame. By moving this cranked lever
in one direction the bolts are shot into the holes to lock the scale frame
to the shafts, and by moving it in the other direction the bolts are drawn
to release the frame and permit the tilting. The Invention is applicable to
wagons or other four-wheeled vehicles as well as to carts or two-wheeled
vehicles, the scale frame in four-wheeled vehicles requiring to rest upon the
front axle as well as to be attached to the rear one, and the arrangement of
the system of levers and scale beam or steelyard may be precisely the same
in a four-wheeled vehicle as in the two-wheeled vehicle.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Edward Newton in the Great Seal Patent Office
on the 24th August 1858.

.
NOW KNOW YE, that I, the said William Edward Newton, 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, reference being had to the Drawing hereunto. annexed,
and to the letters and figures marked thereon (that is to say):-
This Invention consists in the employment of a system of levers and a
frame applied between the body of a cart or other vehicle and its axle or
axles, and combined with a scale beam or steelyard attached to the body in
such a manner as to weigh the load upon the vehicle. It further consists
in a contrivance for securing the body of the cart firmly to the axles when
the weighing apparatus is not in use, and for bringing the cart body and
weighing apparatus into an operative relation when the weighing is to be
performed.
The Invention is illustrated in the accompanying Drawing, in which Fig. 1
is a side view of a cart to which the weighing apparatus has been applied;
Fig. 2 is a back view' of the same; Fig. 3 is a longitudinal vertical section
of the same; and Fig. 4 is a front view of the bolts for securing the body of
the cart to the shafts, shewing also the mode of releasing the bolts, so as to
allow of the cart being tilted. Similar letters of reference indicate corre-
sponding parts in the several Figures.
A represents the body of the cart; B is the axle; C, C, D, D, is a
quadrangular frame attached permanently to the springs S, S, or, if no springs
are used, to the axle B, and serving to support the body A of the cart. This
frame is made separate from the body, and has the shafts T, T, connected to
it by two bolts t, t, (Figures 1 and 2,) and upon these pins the quadrangular.
frame is capable of moving for the purpose of tilting the cart.
At the under side of the rear end of the frame C, C, D, D, which may be
termed, the "scale frame," there are two levers E, E³, seen best in Fig. 2.
These levers are furnished with knife-edged fulcra a, a, which rest. in

page_text: stirrups b, b, suspended from the scale frame, as shown in Fig. 2, and at
the front end of the scale frame two similar levers are applied in a similar
'manner. All of these levers are shown in Fig. 3. Each pair of levers E, E',
has a pair of connecting links 6, 61, (Fig. 2), which connect the two together,
and each lever. E' is connected by a pair of short links c, c, with one of two
short arms d, d, on a shaft e, which extends under the whole length of the
scale frame, and which is suspended by two links f, f, and knife-edged pivots
from two levers F, which work on two pivots g, secured in the outer sides of
the transverse pieces D, D, of the scale frame. This shaft e has at about the
middle of its length a long arm h, whose-end projects beyond one side of the
cart; and is connected by a rod i with the scale beam or steelyard G, which is
suspended by a stirrup j from a bearing, attached to the outside of the
body of the cart, às shown in Fig. 1. The scale beam or steelyard G-is
enclosed by a box H, built on the side of the cart. All the connections are
made with knife-edged pivots similar to those commonly used in scales and
weighing machines. Each of the four levers E, E, E, E, is furnished with
a pointed or nipple-shaped projection k on its upper side to serve as a bearing
for one of four upright. rods: I, I, I, I, which are rigidly attached to the
bottom of the body A. J is shaft having journals fitted to work-in
bearings. 1, 1, secured to the bottoms of the transverse pieces D, D, of the
scale frame: This shaft is furnished at its front end with a lever m, which
stands up in front of the cart, also with two cams n, n, both. of the same
shape, and which occupy positions under the two levers F. There are also
two other cams p, p, both alike, which occupy positions within two frames K, K,
which are bolted to the bottom of the cart body A..
At all times but when the operation of weighing the load is to be performed
the cart body A rests flat upon the scale frame C, C, D, D, as shown in
Fig. 1, in which condition it is locked by the two cams p, p, bearing on the
.bottoms of the two frames K, K. When the shaft J.is in the condition in
which the cams p, p, bear thus upon the frames K,K, the two cam's n, n,
are out of contact with the two levers F; F, and the whole system of levers_is_
relieved of strain. When a load is to be weighed the shaft J is turned--by
means of its lever min a direction to throw up the cams:n, n, under the
levers F, F, which operation unlocks the body of the cart from the scale
frame by the removal of the cams p, p, from contact with the frames K, K,
and causes the cams n, n, to raise the levers F, F, which by means of the
links f, fraise the shaft E, whose arms d,-d; raise the connected-ends-of-the
two levers E, E, by the consequent action of whose bearings k, k, upon
the upright rods I, I, the cart body. is raised from the scale frame, as-is

page_text: shown in Figures, 2, and 3. The shafte with, its arms d, d, and h, now
constitutes a single lever, whose fulcrum is the shaft J, and the whole weight
of the body. is therefore, thrown upon the arms d, d,, while the arm his
connected with the scale-beam or steelyard G. By applying proper weights
to the extremity of the scale beam or steelyard, and by the use of the
movable poise on the graduated: portion thereof,.. the weight of the load
may be accurately. ascertained. When this has, been done, the lever mis to
be moved back again, to allow the body A to come down flat on the scale
frame, and to bring the cams p, p, to a position to lock the body.firmly to the
.said frame..
The system of levers by which the weighing is effected does not interfere
with the tilting of the cart to discharge the load, as, when the body is locked
to the 'scale frame, the said scale frame, and the whole system of levers, and
the cart body are allowed to tilt together when the front of the cart body is.
detached from the shafts, the axles being made to turn in the naves of the
wheels as in the tilting of a common cart. To permit the weighing operation,
however,-the-front-of the body-must-not..be .connected directly to the:shafts
to prevent the tilting, as is the case in a common cart, but the connection
must be made by means of the scale frame. A convenient means of con-
nection between the scale frame and shafts is exhibited in the detached
sectional view, Fig. 4, in which L is a cranked lever fitted to turn loosely on.
the front end of the shaft J, and having attached to it two bolts u, u, which
are arranged to slide through corresponding holes in the shafts and in the
front portions of the side pieces C, C, of the scale frame. By moving this
cranked lever in one direction the bolts are shot into the holes so as to lock
the scale frame to the shafts, and by moving it in the other direction the
bolts are drawn, thereby releasing the frame and permitting the tilting of
the cart.
The Invention is applicable to waggons or other four-wheeled vehicles, as
well as to carts or two-wheeled vehicles. The scale frame in four-wheeled
vehicles is required to rest upon the front axle, as well as to be attached to
the rear one; and the arrangement of the system of levers and scale beam or
steelyard may be precisely the same in a four-wheeled vehicle as in the two-
wheeled vehicle represented in the Drawing.
Having now described the Invention that has been communicated to me
as aforesaid, and having explained the manner of carrying the same into
effect, as described by my foreign correspondent, I claim,―
First, the application of a system of levers and a frame C, C, D, E, or its
equivalent, to the body of a cart or other vehicle in combination with a scale

page_text: beam or steelyard attached to the said body in any manner, as herein
described.
Second, I claim the use of the shaft J, with its cams n, n, and p, p, and
the frames K, K, applied in combination with each other and with the body
of the vehicle and the weighing apparatus, in the manner as described,
for the purpose of locking the body to the axles, or bringing it into an
operative relation with the weighing apparatus for the purpose of weighing
the load.
In witness whereof, I, the said William Edward Newton, have hereunto
set my hand and seal, the Twenty-fourth day of August, in the year
of our Lord One thousand eight hundred and fifty-eight.
