FRIEDRICH CARL GLASER, of Berlin, in the Kingdom of Prussia, and Empire of
Germany Engineer, and Patent Solicitor, "IMPROVEMENTS IN APPARATUS FOR
MEASURING, RECORDING, AND INDICATING THE SPEED OF RAILWAY TRAINS." A
Communication from the Werkzeug und Maschinenfabrik- Oerlikon (the Oerlikon
Tool and Machine Manufactory of Oerlikon (Switzerland)
The speed measurer for Railway Trains the subject of this invention consists of a
system of branch elements or apparatus which is attached to a revolving axle and
is held by a spring in different positions at different degrees of tension of the same,
which positions correspond to the various velocities of revolution. These different
positions are made use of so as to allow of the speeds being read off and recorded,
the latter in combination with a clock.
On the accompanying five sheets of Drawing:-
Figures 1 1a and 1b (Sheet I) shows this Invention applied to a Locomotive.
Figure 2 (Sheet II) is a sectional plan showing part of the apparatus in contact
with the wheel of Locomotive drawn to an enlarged scale.
Figure 2 (Sheet III) is a Sectional Elevation of same
Figure 2b (Sheet IV) an end view partly in section and
Figures 3 and 4 (Sheet V) show the recording and indicating apparatus; in
sectional elevation at Fig: 3, and in front view partly in section at Fig: 4.
The axle xx¹ carries the system of branch apparatus or elements together with
the spring f. This axle receives its motion from a gauged measuring disc 5, which

page_text: is so fitted on a shaft y intersecting the axis that it is to some extent moveable in
a plane normal to the axle x, x¹.
The transfer of motion is effected by toothed wheels. The operation of the
gauged disc 5, which is made of hard material, (chilled cast iron) is effected by
friction, generally from the tyre, or it may be from another part which is moved
at a velocity, equal or proportionate to that of which the train travels.
The axle x, x¹, carries the two pivots o, o, and the connecting rod joint g. The
system of branch elements or apparatus, consisting of a disc shaped main element S, S,
of a transmission rod e, 1, 1, and of a connecting rod e, g, is so suspended on the
points o that it may oscillate between the drawn and the dotted positions
(Fig 2); it is of special importance to fix the angles correspondingly. On the
transmission rod 1, l, in the direction of the length of the axle x, x', is arranged the
stuffing box h which is held by the spring f this being attached to the end of the
rotating axle x by the screws m, m.
When the axle x, x¹, rotates, the spring f, by reason of the centrifugal motion
which takes place in the system of branch elements, has a tendency to expand
through a certain extent. The movement resulting therefrom is transferred by a
small light rod i, which must not turn, to the place where it has to be read off and
recorded, generally in the case of locomotives up near the Engine Driver.
At this uppermost end the motion is made visible on a figured sheet by means
of small toothed wheels and toothed rods through the pointer r.
The small rod i at the part where the indicating (writing) apparatus is attached
(see Fig: 3ª) is provided with a slotted parts which carries a small disc. This
disc rolls in the guides u, u, in which movement it carries at this point the
indicating rod direct.
In the slot of the parts is also attached the crank lever S. S. projecting from
the registering apparatus, which lever is fitted on the stud E; this moves by means
of the point E¹ the oscillating lever n which at one end carries the marking
pencilj, and is so held at the other end by the small connecting rod d that the
pencil on the movement of the lever S. S. describes a straight line.
These levers are as a whole fixed to the plate H, which may itself oscillate on
the points S¹, S, and be brought into position where the marking pencil ; is
removed away from the roller B which moves the strip of paper under the marking
pencil so that the roller B is free. For pressing the strip of paper to the roller B,
the rollers B1, B2, are also provided, and these are so connected to the plate H that
they bear by spring pressure against the roller B, when the plate H is brought to
its normal position. These three rollers B, B1, B2, carry besides at one end
corresponding small toothed wheels f, f¹, f, which in their normal position are in
gear. Also to the plate H is fixed the paper strip in the wound position. It is
accordingly obvious, that after such a roll of paper has been put within the opened
plate H, only the part of the paper hanging down must be slightly held and the
plate H shut back to its normal position so that the strip of paper lies properly on
the roller B and between the pressing rollers B¹ B². The shaft B is then moved by
the clock and therewith also moves the strip of paper lying on it corresponding
proportionately to the time; the pencil į marks its position hereon, according to
the rate of speed being travelled at, at the time

On the accompanying 3 Sheets of Drawing:-
Figures 1, 1 and 1b (Sheet 1) show this Invention applied to a Locomotive.

The axle X, X' carries the system of branch apparatus or elements together with
the spring f. This axle receives its motion from a gauged measuring disc 5, which
is so fitted on a shaft y intersecting the axis that is to some extent moveable in a
plane normal to the axle X, X¹,

gauged disc 5, which is made of hard material, (chilled cast iron) is effected by
friction, generally from the tyre, or it may be from another part which is moved at
a velocity, equal or proportionate to that at which the train travels.
The axle X, X', carries the two pivots o, o, and the connecting rod joint g; The
system of branch elements or apparatus consisting of a disc shaped main element S, S,
of a transmission rod e, l, l, and of a connecting rod e, g, is so suspended on the
pivots o, that it may oscillate between the drawn and the dotted positions (Fig: 2b);
it is of special importance to fix the angles correspondingly. On the transmission
rod 1, l, in the direction of the length of the axle X, X, is arranged the stuffing
box h, which is held by the spring f, this being attached to the end of the rotating
axle X, by the screws m, m.
When the axle X, X¹, rotates the spring f, by reason of the centrifugal action
which takes place in the system of branch elements has a tendency to expand to a
certain extent. The movement resulting therefrom is transferred by a small light
rod i, which must not turn to the place where it has to be read off and recorded,
generally in the case of locomotives up near the Engine Driver.
At this uppermost end the motion is made visible on a figured sheet by means of
small toothed wheels and toothed rods through the pointer r.
The small rod i at the part where the indicating (writing) apparatus is attached
(See Fig: 3) is provided with a slotted parts which carries a small disc. This
disc rolls in the guides u, u, in which movement it carries at this point the
indicating rod direct.
In the slot of the parts is also attached the crank lever G G projecting from the
registering apparatus, which lever is fitted on the stud E; this moves by means of

page_text: the point E¹, the oscillating lever n which at one end carries the marking pencil j,
and is so held at the other end by the small connecting rod d, that the pencil j, on
the movement of the lever G G describes a straight line
These levers are as a whole fixed to the plate H, which may itself oscillate on
the points S¹, S, and be brought into a position where the marking pencil j, is
removed away from the roller B, which moves the strip of paper under the marking
pencil so that the roller B is free. For pressing the strip of paper to the roller B,
the rollers B1, B2, are also provided and these are so connected to the plate H,
that they bear by spring pressure against the roller B, when the plate H is brought
to its normal position. These three rollers B, B¹, B³, carry besides at one end
corresponding small toothed wheels e e¹ e² which in their normal position are in
gear. Also to the plate H, is fixed the paper strip l, in the wound position. It is
accordingly obvious, that after such a roll of paper has been put within the opened
plate H, only the part of the paper hanging down must be slightly held and the
plate H shut back to its normal position so that the strip of paper lies properly on
the roller B, and between the pressing rollers B', B².
The shaft B is then moved by the clockwork and therewith also moves the strip
of paper lying on it corresponding proportionately to the time; the pencil j, marks
its position hereon according to the rate of speed being travelled at, at the time.
Having now described and ascertained the nature of the Invention communicated
to me as aforesaid.
