PROVISIONAL SPECIFICATION.
Improvements in Weighing Machines.
I, JAMES WATKINS of St. James's End, Northampton, Machinist, do hereby
declare the nature of this invention to be as follows:-
This invention relates to the kind of weighing apparatus the beam of which is an
unequal-armed lever with counterpoise weights and is designed for use on wagons
or other vehicles, as well as in yards and warehouses where coal and the rougher
class of goods are weighed.
It consists of a base preferably of wood, two vertical standards connecting the
base to a horizontal bar the end of which is turned up vertically and fitted with
bearings to receive the lever which is arranged to work in cup-shaped bearings
on the frame or may be hung on a horizontal bolt. The frame on which the
cup centres are fixed is made in parts, so that the bearings can be attached
removably to the frame, and can therefore be easily taken out and repaired
when worn.
A scale pan or scoop of the usual kind is suspended from the short end of the
lever, or beam, and the weights are suspended from the other, discs of metal being
used, as on the ordinary weighing machine.
The whole apparatus is simple, strong and inexpensive, being made entirely of
wrought iron and steel. It can be constructed in a low compact form to attach to
coal carts, or on high standards with triangular base and wheels for yard use.
The end of the lever can be held firm when travelling by a vertical guide bar and
pin to prevent wear, and it can be quickly removed from the wagon when not in use.
The great advantage of my apparatus for such purposes is its portability, there being
no heavy weights to move about.

COMPLETE SPECIFICATION.
Improvements in Weighing Machines.
I, JAMES WATKINS of St. James's End, Northampton, Machinist, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to the kind of weighing apparatus the beam of which is an
unequal-armed lever with counterpoise weights, and is designed for use on wagons
or other vehicles, as well as in yards and warehouses where coal and the rougher
class of goods are weighed.
It consists of a base preferably of wood, two vertical standards connecting the
base to a horizontal bar the end of which is turned up vertically and fitted with
bearings to receive the lever which is arranged to work in cup-shaped bearings
in the frame, or may be hung on a horizontal bolt. The frame on which the
cup centres are fixed is made in parts, so that the bearings can be attached
removably to the frame, and can therefore be easily taken out and repaired
when worn.
A scale pan or scoop of the usual kind is suspended from the short end of the
lever, or beam, and the weights are suspended from the other end, discs of metal
being used, as on the ordinary weighing machine.

page_text: In the accompanying drawing is shewn an elevation of my improved weighing
machine.mounted on the stand g. The weighing apparatus consists of a wrought iron
frame a, composed of two bars placed side by side with bearings at a', and a vertical
guide-bar c, and also the lever beam.b, on the bearings a', and between the double
guide-bar c.
The suspending weight holder e, and the scale-pan d. The latter can be of
any suitable form. The weights f, are the portable kind employed on weighing
machines.
The whole apparatus is simple, strong, and inexpensive, being made entirely of
wrought iron and steel. It can be constructed in a low compact form to attach to
coal carts or on high standards as shewn for yard use. The end of the lever can be
held, firm when travelling by a vertical drop catch or pin to prevent wear, and the
apparatus can be quickly removed from the wagon when not in use.
The great
advantage of my apparatus for such purposes is its portability, there being no heavy
weights to move about.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
In a portable weighing machine the combination of the frame a, lever arm b,
guide bar c, suspending scale d, suspending weight holder e, flat weights f, with or
without the stand g, as herein described and set forth.
