I FREDERIK CASSE of Copenhagen Denmark Civil Engineer do hereby declare
the nature of this invention, to be as follows:-
In the specification of patent No. 100 of 1882 are described apparatus for
weighing railway rolling stock. In these apparatus an axle & situated between
and parallel with the rails is on the one hand connected with a steelyard for
weighing and on the other hand connected with lever systems arranged transversely
to the track and connected with weighing rails which receive the weight of the
vehicle. Now this my present invention refers to improvements in connection
with weighing apparatus of the aforesaid description.
Parallel to the track and close up against the outside of its rails are placed
two or more proportionately short horizontal rails in such a way, that they can
be moved vertically so as to get their upper faces somewhat above or below the
level of the track.
These movable rails which I call the weighing-rails are placed two and two
opposite each other and are transversely mutually rigidly connected. The distance
between the different pairs of weighing-rails is made to suit the limits of the
axle distances of the railway vehicles.
Each of these weighing-rails rests upon knife edges which are parallel to the
track and fixed on arms projecting from a tubular or other axle placed horizontally
outside and parallel to the track at a short distance from it. This axle is at both
ends provided with knife edges poised freely on bearings, and it is provided with
an arm which passes transversely to and below the track rails and the weighing
rails, towards the middle of the track, where the underside of this arm is provided
with a knife edge. For every pair of weighing rails there are two such axles
with their arms projecting to the centre line of the track, independent of each

standards or columns which transfer the pressure of the arms to knife edges fixed
upon as many other arms all projecting from a long horizontal axle parallel to
the track and poised with knife edges upon bearings at both ends and if necessary
also intermediately. This long axle corresponds to the axle d in the aforesaid patent.
From this long axle projects moreover transversely to the track a long arm the free
end of which through a knife edge is hung in the steelyard connecting rod.
When a vehicle has to be weighed, its wheels are made to rest upon the weighing
rails the top of these being then slightly above the level of the track, but when
weighing is not going on, then the top of the weighing rails must be below the level
of the track so as to allow trains to pass it without touching the weighing rails, and
for this purpose the above named vertical standards or columns have knuckle joint
action or equivalent action so that they can easily be shortened and again extended,
thus giving vertical movement to the weighing rails. The knuckle joints may be
constructed as follows. Each standard consists of two lengths or links of equal
a little out of the
length which are jointed together, the fulcrum of the joint being
centro line of the column, and each link being on the opposite side of the said centre
line provided with a projecting nose or stop, which stops abut against each other when
the column is straight or unbroken. The said fulcrum joints are by means of con-
necting rods connected to arms on a weigh shaft arranged transversely to the track.
By turning this weigh shaft the aforesaid knuckle joint columns are brought into the
straight and rigid or into the bent or broken position and thus made long or short as
required, whereby the weighing rails are raised or lowered. The knife edge bearings
at the upper and lower ends of the columns are situated in blocks pivotted thereto.

page_text: Improvements in Weighing Machines for Railway Rolling Stock.
I FREDERIK CASSE of Copenhagen, Denmark, Civil Engineer 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 :-
In the specification of patent No. 100 of 1882 are described apparatus for weighing
railway rolling stock. In those apparatus an axle d situated between and parallel
with the rails is on the one hand connected with a steel yard for weighing and on the
other hand connected with lever systems arranged transversely to the track and
connected with weighing rails which receive the weight of the vehicle. Now this my
present invention refers to improvements in connection with weighing apparatus of
the aforesaid description.
In the accompanying drawings Figure 1. is a plan view of an apparatus constructed
according to my invention, Figure 2. is a longitudinal section on line A. B Figure 1,
and Figure 3 is a transverse section on line C. D. Figure 1. Figures 4 to 10 are
detail views.
Parallel to the track and close up against the outside of its rails A are placed two
horizontal rails A¹ (or it may be more than two all according to the number of wheel
axles of the railway carriage to be weighed) in such a way that they can be moved
vertically or up and down so as to get their upper faces somewhat above the level of
the track A A when the apparatus is to be used for weighing or below the level of the
track when the apparatus is out of use.
These movable rails A' which I call the weighing rails are placed two and two
opposite each other and are transversely, mutually, rigidly connected, for instance as
here shown by means of rail shaped cross bars A². The rails A are laterally recessed
as shown and the weighing rails A' are situated in the recesses. The distance between
the different pairs of weighing rails A' A' is made to suit the limits of axle distances
of the railway vehicles.
Each of these weighing rails A' rests upon knife edges which are parallel to
the track and fixed on arms g, projecting from a tubular axle placed horizontally
outside and parallel to the track at a short distance from it. One weighing
rail A in each pair, is however by preference supported directly and the other
indirectly on the said knife edges i as will be understood partly by reference to
Figures 1 and 3 but more especially by the detail views Figures 7 and 8 and 9
and 10. Figure 7 is a side view and Figure 8 cross section on line T. U. of
the end of one directly supported weighing rail A' which is formed with V groove
on the underside. But Figure 9 shows in side view and Figure 10 in cross
section on line R. S. how the opposite weighing rail A' is supported indirectly viz.
hrough the intervention of a loop-shaped piece W which has a V groove that is

page_text: supported on the knife edges i on the army of the weigh shaft or axle f. The piece W.
is movable on two pivots provided thereon and supported in V grooves in lower
projecting arms of the weighing rail A. Each axle is at both ends provided with
knife edges poised freely on bearings and it is provided with an arm h which
passes in a direction transversely to and below the track rails, A and the weighing
rails A towards the middle of the track where the underside of each arm h is
provided with a knife edge. For every pair of weighing rails A¹ there are two
such axles with their arms projecting to the centre line of the track independent
of each other, but all these arms rest with their knife edges upon just as many
vertical standards or columns E. F. Figure 3, which transfer the pressure of the
arms to the knife edges o fixed upon as many other arms all projecting from a
long horizontal axle parranged parrallel to the track and poised with knife edges r
upon bearing at both ends and if necessary also intermediately. This long axle p
corresponds to the axle in the aforesaid patent specification. From this axle p
projects moreover transversely to the track a long arm & the free end of which through
a knife edge is hung in the steel yard connecting rod v.
When a vehicle has to be weighed its wheels are made to rest upon the weighing
rails A, the upper surface of these latter being then slightly above the level of the
track rails A. A. but when weighing is not going on then the upper surface of the
weighing rails A' must be below the level of the track so as to allow trains to pass it
without touching the weighing rails, and for this purpose the above named vertical
standards E. F. have knuckle joint or toggle-joint or equivalent action so that they
can easily be shortened and again extended thus giving vertical movement to the
weighing rails. The knuckle or toggle joints may be constructed as follows, and as
more clearly shown in the detail views, Figures 4 and 5 which are end view and side
view respectively of a column when in the erect position, and Figure 6 a side
view of same when in the partly collapsed or shortened position or condition. Each
standard consists of two lenghts or links E and F which are conveniently of equal
length and jointed together by means of a pin G. whilst the free end of each of them
is provided with an upper and lower block J. and J¹ respectively pivotted thereto and
furnished with a V groove as to form the bearing for a knife edge. The pin G. has
its fulcrum a little out of a straight line drawn through the fulcrums of the pivots of
the blocks J. and J' as seen in Figure 5. and each link is on the opposite side of the
said straight line provided with a projecting nose or stop H, which stops abut against
cach other when the column is straight or unbroken. The said fulcrum joint pins G.
are by means of connecting rods N. connected to arms O. on a weigh shaft P.
arranged transversely to the track. By turning this weigh shaft P. a hand lever Q
being fixed thereon for that purpose the toggle joint. columns E. F. are brought into
the straight and rigid position Figure 5 or into the bent or broken position Figure 6.
indicated also by the arrow and dotted lines in Figure 2. and thus made long or short
as required, whereby the weighing rails A through the intervention of the levers h
and g on the weigh shafts are respectively raised or lowered. The lower blocks J'
are kept from shifting in the length direction of the knife edges o by suitable lateral
projections on the latter as shown in Figure 2. Each two adjoining columns are
connected by short links M. Figures 1. and 2.
In order to weigh a railway vehicle the axle P. is first by means of the hand lever Q
turned in the direction of the arrow so that the toggle links E. and F form a suitable
angle whereby the weighing rails A' are lowered below the level of the track. The
vehicle is then run into position each wheel being over some part of a weighing rail,
no matter whether near the middle or near one end. The axle P is then by means of
the hand lever Q turned back in a direction opposite to that of the arrow whereby
the columns E. F. are straightened and the wheels raised somewhat above the level
of the rails A and resting solely on the weighing rails A'. The weight of the vehicle
will then by means of the levers g. and h. columns E. F. and levers q. and t. be
transferred to the steel-yard connecting rod t and steel-yard the sliding weight =
being adjusted to balance the weight and indicate its amount.
