IMPROVEMENTS IN SCALES AND BALANCES
Year: 1885

do hereby declare the nature of my invention for IMPROVEMENTS IN SCALES AND
BALANCES to be as follows:-
The Beam of a Balance or Pair of Scales constructed according to my invention
has a projection on each side on the upper part of the Beam at its centre into each
of which a pointed piece of steel is secured by screwing or otherwise the points
being directed downwards-At or near each end of the Beam and on each side of
it on the lower part are similar projections but preferably smaller than those just
described into these projections pointed pieces of steel are secured with the points
directed upwards-All these six points are in the same horizontal plane when the
Scale beam is at rest in its central position These points just described take the
place of the "Knife Edges" used in ordinary scales and they take their bearing in-
suitably shaped cups or sockets formed of Agate or other suitable material. These'
cups are cemented or otherwise fastened into double boxes whereof the central 'one
is attached to the piece by which the scale or balance is suspended and the end
ones having rings from which the scale pans are hung. I provide small hinged
doors in the boxes to give access for cleaning The boxes are closed on the outer
side and open on the inner side that is the side next to the scale beam, there is one
double box in the centre the two parts of it being connected above and below the
scale beam and one double box at each end of the scale beam the two parts of each
being connected above and below the Scale Beam.

page_text: WILLIAM KLOEN 71 St Peters Road Birmingham do hereby declare the nature
of my invention for IMPROVEMENTS IN SCALES AND BALANCES and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement as follows:—
The Beam of a Balance or Pan of Scales constructed according to my invention
has a projection on each side on the upper part of the Beam at its centre into each
of which a pointed piece of steel is secured by screwing or otherwise the points
being directed downwards.
.
At or near each end of the beam and on each side of it on the lower part are
similar projections but preferably smaller than those just described into these pro-
jections pointed pieces of steel are secured with the points directed upwards all
these six points are in the same horizontal plane when the scale Beam is at rest on
its central position.
"
These points just described take the place of the 'Knife Edges" used in
ordinary Scales and they take their bearing in suitably shaped cups or sockets
formed of Agate or other suitable material These cups are cemented or otherwise
fastened into double boxes whereof the central one is attached to the piece by
which the Scale or Balance is suspended and the end ones have rings from which
the scale Pans are hung I provide small hinged doors in the boxes to give access
for cleaning The boxes are closed on the outer side and open on the inner side
that is the side next the scale Beam there is one double box in the centre the two
parts of it being connected above and below the Scale beam and one double box at
each end of the Scale Beam the two parts of each being connected above and below
the Scale Beam.
And in order that this my said Invention may be more clearly understood
I have prepared the accompanying sheet of drawings by the aid of which I will
now proceed to describe it similar letters of reference denote similar parts in each
and every figure wherein they occur.

page_text: Fig. 13. is a plan of the same.
Fig. 14. is a small connecting Pin.
Fig. 15. is a Distance Piece.
The Scale Beam "a" (Figs. 1. 2. 3 4. 8 9. 10) is made in any usual shape and of
suitable materials it has at its centre on each side at its upper part projecting
pieces al al and at each end on each side on its lower part projecting pieces a² a¹
In the centre on the top edges is the usual pointer a with the point a To the
projections a¹ a¹ are secured (preferably by screwing) the points b. shewn detached
in Fig. 11 and shewn in position in Fig. 1. 3. 8 9. 10 these are made preferably of
steel with hardened points. 63 is the screwed part which enters a tapped hole in
the projection a¹ and b¹ is a part made hexagonal for convenience in screwing in
ccare similar points which are screwed into the projecting pieces a³ a³ at the ends of
the scale beam These are similar in shape to the points 6 having screwed parts c³ c³
and hexagonal parts c² c¹ but I prefer to make them smaller than the points b. b.
d (Fig. 1. 2. 3) is the central double box having a recess d'd' to receive the
sockets ff d d are sinall hinged lids or doors for the purpose of access for
cleaning d d³ are the hinges for same these doors are made so as to snap tightly
projections d' d' are provided for the insertion of the thumb nail for opening them
dsds are downward projections and do is the central piece by which the entire
balance is suspended "d' being the pointer piece to shew in combination with the
pointer a when the balance is in equilibrium.
It is to be understood that the whole of dis made in a piece and the projections d³
are united after the scale beam a is put in place by means of a pin 7 (Figs. 1. 3 & 14)
passing through a distance piece "m" and secured by nuts 1, 1, or I may make the
lower part of d. (that is the part below the scale beam) with an enlarged opening
so that the ends a' a' of the scale beam may be threaded through it when putting
the parts together without the necessity of using a loose pin l. When the balance
is in a state of equilibrium the extreme points of b b and c c c c are all in the same
horizontal plane.
The end boxes e. a. are similar in construction to the box d but inverted They
are each provided with recesses el e¹ binged lids e e³ with hinges ees and pro-
jections e e for opening. These lids are also for access for cleaning and they are
made to snap tightly so that they may not fall open.
I prefer this way of making these lids but I may make them to slide instead of
to hinge if desired. The cups or Bockets ƒ ƒ (Figs. 1. 3. 12 & 13) are made
preferably of Agate for the points b to work in they are cemented at "g" into the
recesses & in the box d.
The sockets for the points c c at the ends of the beam are similar but smaller
they are shewn at h. (Figs 1. 2. & 4) and are cemented at j into the sockets e¹ e¹ of
the boxes e. a. in the same manner as the sockets f f are cemented into the box d
but in an inverted position kk are the usual rings for connecting the end
boxes e. e. with the Scale Pans.
I have shewn on my drawings and described in this specification the most usual
method of carrying my invention into effect but I do not limit myself to the exact
configuration of parts shewn nor to the materials specified but may vary either
while not departing from the principle of my said invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare what
I claim is
First. The use of points of steel or other similar suitable material working in
cups or sockets formed in Agate or other suitable material instead of the " Knife
Edges" commonly employed in Scale Beams.

page_text: Second. The boxes, as shewn and described to contain the sockets previously
mentioned and furnished with lids for access for cleaning-The construction and
combination of parts as hereinbefore specified and as shewn on accompanying
drawing the whole forming an improved. balance or Scale Beam and its
appurtances.
