PROVISIONAL SPECIFICATION.
An Improved Balance having a Sliding Beam.
J. SAMUEL WILSON SUFFIELD, of 71, Lionel Street, Birmingham, in the County
of Warwick, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
The object of this improved balance is to obtain a series of weighings by means
of one standard weight, as for example weights of letters and parcels.
My improved balance consists of a pillar stand carrying at its upper end a cross-
head. At each end of this crosshead is an upright arm, and both of these arms are
slotted to allow the balance beam to pass freely through the said slots.
A knife-edge is fitted into the bottom of one of the slots, and on this knife-edge the
balance beam turns. The underside of the balance beam is provided with a series
of small notches to take on to the knife-edge. At one end of the balance beam is hung
the standard weight, and at the other end the article to be weighed. If the balance
beam be then adjusted, by means of the series of small notches, in such a position on
the knife-edge as to cause the standard weight to balance the article to be weighed,
the weight of the latter can be ascertained in the following manner. On the balance
beam is set out a scale of weights in relation to the notches before mentioned; and
the weight-mark corresponding to the notch on the knife-edge, when the standard
weight and the article to be weighed balance each other, gives the weight of the said
article.
The scales of weights on the balances may be of general application or have relation
to any special trade or requirement.
COMPLETE SPECIFICATION.
An Improved Balance having a Sliding Beam.
I, SAMUEL WILSON SUFFIELD, of 71, Lionel Street, Birmingham, in the County
of Warwick, Manufacturer, 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
:-
The object of this improved balance is to obtain a series of weighings by means of
one standard weight, as for example the weights of letters and parcels.
My improved balance consists of a pillar stand carrying at its upper end a crosshead.
At each end of this crosshead is an upright arin and both of these arms are slotted to
allow the balance beam to pass freely through the said slots.
A knife edge is fitted into the bottom of one of the slots, and on this knife edge.
the balance beam turns. The underside of the balance beam is provided with a series
of small notches to take on to the knife edge. At one end of the balance beam is
hung the standard weight, and at the other end the article to be weighed. By standard
weight I mean that the weight is determined at the outset according to the scale of
weighings for which the balance is made, and that each weight is then the standard
for that balance. If the balance beam be then adjusted by means of the series of
small notches, in such a position on the knife edge as to cause the standard weight to
balance the article to be weighed, the weight of the latter can be ascertained in the
following manner. On the balance beam is set out a scale of weights in relation to
the notches before mentioned and the weight mark corresponding to the notch on
the knife edge, when the standard weight and the article to be weighed balance-
each other, gives the weight of the said article.

page_text: The scales of weights on the balances may be of general application, or have relation
to any special trade or requirement.
The accompanying drawing shews the construction of my improved balance.
The pillar a carries a crosshead having at each end an upright arm and c
Both these arms are slotted to allow the balance beam dio pass freely through the
said slots. A knife edge e is fitted into the bottom of the slot in the arm c and on this
knife edge the beam & turns.
In the drawing the beam is shewn with divisions for postal weighings from ounce
to 8 ounces and at each division is a small ^ notch to take on to the knife edge. fis
the standard weight suitable for the scale of weights marked upon the beam. On
the plate g the letter h, or other article to be weighed, is placed and the beam dis
adjusted on the knife edge until the article to be weighed balances or nearly balances
the weight f.
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:
1. An Improved Balance having a sliding beam and constructed to obtain. a series
of weighings by means of one standard weight as described and illustrated.
Dated this 16th day of September 1889.
