motion is transmitted to a vertical spindle by means of bevil-gear and at the
upper end of this spindle is mounted a horizontal disc. Upon this disc is fixed a
pin which at each rotation of the said disc actuates a click which latter causes the
first wheel of a counter to be moved through a certain angular distance so that the
said counter by integrating the number of revolutions of the disc indicates the distance
travelled within a given time.
A small friction wheel is arranged at right angles to the said disc and in
such manner that it and its axle can be moved by means of the said disc.
This axle is held between centres. Above the disc are two horizontal slide
rails upon which a slide is able to move backwards and forwards. This slide
is provided with a slot through which passes the friction wheel and is itself
fixed to the frame or case of the apparatus by means of counter-springs which
tend to draw the slide and the friction wheel towards the centre of the disc:
this latter movement being limited by stops fixed in such position upon the
slide rails that the friction wheel is maintained at a distance equal to its own
radius from the centre of the disc. For the purpose of moving the slide against
and in opposite direction to the said counter-springs two rods are attached to the
slide and pass through the casing of the apparatus. Outside thereof they are con-
nected together by a crosspiece which latter is connected with the coupling hook of
the wagon by means of levers in such manner that the force which acts upon the
coupling is communicated in a fixed ratio to the rods hereinbefore mentioned. The
latter overpowering the pull of the counter-springs move the slide and at the same
time the friction wheel nearer the periphery of the disc. This causes the velocity
of rotation of the friction wheel to be increased which increased velocity is
indicated by the counter which also indicates the power given out during an
interval from the number of rotations that the disc and friction wheel make during
the said interval. An indication of the pulling force may also be obtained by
means of a scale upon one of the slide rails.

COMPLETE SPECIFICATION.
A New or Improved Power and Distance Meter.
I, HEINRICH TEODOROWITCH, Chief of the Railway Works of Nikolajew,
Russia, 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 :-
My invention relates to a new or improved power and distance meter for railway
purposes by which certain advantages are obtained.

page_text: :
In carrying my invention into effect I mount a pulley upon the axle of a railway
waggon or carriage and by means of a driving belt connect the said pulley with
a second pulley placed on an axle parallel with the first. From this latter axle
motion is transmitted to a vertical spindle by means of bevil-gear and at the
upper end of this spindle is mounted a horizontal disc. Upon this disc is fixed a
pin which at each rotation of the said disc actuates a click which latter causes the
first wheel of a counter to be moved through a certain angular distance so that
the said counter by integrating the number of revolutions of the disc indicates the
distance travelled within a given time.
For the
A small friction wheel is arranged at right angles to the said disc and in such
manner that it and its axle can be moved by means of the said disc. This axle is
held between centres. Above the disc are two horizontal slide rails upon which a
slide is able to move backwards and forwards. This slide is provided with a slot
through which passes the friction wheel and is itself fixed to the frame or case of
the apparatus by means of counter-springs which tend to draw the slide and the
friction wheel towards the centre of the disc: this latter movement being limited
by stops fixed in such position upon the slide rails that the friction wheel is main-
tained at a distance equal to its own radius from the centre of the disc.
purpose of moving the slide against and in opposite direction to the said counter-
springs two rods are attached to the slide and pass through the casing of the
apparatus. Outside thereof they are connected together by a cross-piece which
latter is connected with the coupling hook of the waggon by means of levers in
such manner that the force which acts upon the coupling is comminicated in a
fixed ratio to the reds hereinbefore mentioned. The latter overpowering the pull
of the counter-springs, move the slide and at the same time the friction wheel
nearer the periphery of the disc. This causes the velocity of rotation of the
friction wheel to be increased which increased velocity is indicated by the counter
which also indicates the power given out during an interval from the number of
rotations that the disc and friction wheel make during the said interval.
indication of the pulling force may also be obtained by means of a scale apon one
of the slide rails.
An
Having now described my invention in general terms 1 shall proceed to describe
it more in detail and for that purpose shall refer to the accompanying drawings
which will clearly illustrate my invention.
Figure 1 is a plan of the apparatus.
Figure 2 is a longitudinal section on the line 1-1 of Figure 1.
Figure 3 is a transverse section on the line 2-2 of Figure 1.
Figure 4 is the transmitting mechanism from the car to the dynamometer.
Figure 5 shows the fitting and arrangement of the power and speed measurer
on a railway car.
From an inspection of the entire apparatus will be seen a box or case A, which
is made practically air tight, by means of a cover completely closing it. In this
box is mounted a vertical spindle b, which is mounted within the bearings e and d,
and at its upper end a steel disc a is supported.
. Near the other end of the spindle b, is a bevil wheel, which gears in another
bevil wheel mounted on the axle e. This axle e is rotated by means of a pulley g
connected with the car axle by means of a suitable belt.
The disc a, upon rotating pushes the pin a' against the lever-click t, which
partially rotates the first tooth wheel #, thus counting by means of a suitable
counting apparatus. Upon the wheel making a complete revolution the pin
on the wheel u, strikes a similar lever-click or ratchet w and thus moves the second
wheel ahead one tooth. The wheel through a complete revolution operates
the lever-click ¹ and the wheel in the same manner.
The axles of the wheels u, u, u are supplied with arms or pointers arranged
⚫ over suitable dials so placed that they can be readily examined.
A short distance above the disc a is placed an axle 4, upon which is mounted the

page_text: friction wheel k; the axle being mounted between the centre supports m and n
and is so mounted that as the disc a rotates the friction wheel & which bears upon
the disc a and the axle are both rotated. The friction wheel & is mounted within
a suitable supporting slide o to which the springs pp on the supporting frame are
secured and this slide o slides freely on the slide rails r.
The counter springs pp tend to constantly force the slide o and also the friction
wheel k towards the centre of the disc a which movement is limited by means of
the stops ss.
On the other side of the slide o are two rods 99 by means of which the slide o
is pulled against the action of the springs. The rods 9 are provided with a
cross head A'. The latter is connected to the car coupling in such a manner that
the slide o is exactly counterbalanced by the resistance of the car and as the
rods 7 pull up so that the slide o subjects the friction wheel & to the action of the
springs pp it is moved a little out of its normal position shown in Figure 1 nearer
to the edge of the disc a. The further the friction wheel is moved from the
centre of the disc a the faster it will rotate.
The eccentric . is connected with the friction wheel and axle so that by its
rotation the lever y is operated and the ratchet is moved. By this means the
ratchet will turn a pointer on the dial. By the pointer operating the resistance
of the car will be readily seen.

The car is provided with an ordinary coupling I (Figure 4) provided with a
shoulder engaging with the lever G which turns on the pivot Hand which has
one end through the link G. The lever Falso passes through this link G¹ and is
pivoted at F. From the outer end of the lever F is a pulling rod E, secured to
the vertical lever C, which is pivoted at D. On the other end of C, is the con-
necting rod B, attached to the cross beam A, and the rods q. 7. By this trans-
mitting mechanism a movement of the coupling I will be transmitted to the cross-
head A', and the slide o will be moved in a corresponding manner.
The mechanism from the coupling I to the lever C is constructed of hard metal
(preferably steel) and has so little free play that the cross-head A' and the slide o
move practically continuously with the aforesaid coupling.
One of the slide rails r, is provided with a suitable scale so that the amount
of the resistance is indicated somewhat in the manner of an ordinary dynamo-
meter.
It will be seen that the resistance offered by the railway car is variable and
that the friction wheel k, will not remain in the same position relative to the
centre of the disc a but will move to and fro; such movement being shown on the
scale 7.
The distance traversed by the car in a certain space of time can be calculated
by any of the known formule.
The proper setting up of the apparatus in a railway car is shown in Figure 5.
The box A is mounted upon a table which is secured to a car frame. An adjust-
able roller M regulates the strain of the belt, passing from the axle of the car to
the belt roller
y.
In order to determine the force and direction of the wind a wind vane and
anemometer N is placed above the car.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
1. The new or improved power and distance meter substantially as set forth.
2. In an apparatus for the purposes mentioned the combination of a horizontal
lisc a connected with and rotated by the wheels of the vehicle and a friction
wheel bearing upon said horizontal dise and connected with the coupling of the
vehicle in such a manner that as the resistance of the vehicle increases or decreases
he friction wheel will be moved further from or nearer to the centre of the

page_text: horizontal disc a and its speed of rotation will increase or decrease, such increase
or decrease of speed being indicated upon a proper indicator.
