I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool, and 6. Bank Street,
Manchester, both in the County of Lancaster, and 323, High Holborn, in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this
invention to be as follows:-
On the laminated springs above the axle there rests a block preferably of lead
with a fulcrum, which block can be turned upside round an axis. The bottom
plate of this block is screwed to the upper flange, that is, the lid of the springs, by
means of two screws. Owing to the shocks caused by running over unevennesses
in a railway line (striking or pitching) the block weighing about 7 kg. is lifted or
pushed up about 1 cm. from its fulcrum. This amount of movement is increased
two-fold at the ends of the plate bearing the block, and also by a screw spring in
the interior of the block. The movement of an adjusting screw at the end of the
block plate produced thereby is transferred to an elbow lever and from it by means
of wire rods to a second elbow lever. By the movement of this latter lever, a
discharging valve is operated. This valve is connected by an india rubber
hose with a reservoir which may be conveniently fastened to the window of the
railway car.
This reservoir contains a colouring liquid, for instance a thin solution of aniline.
At each shock during the journey, no matter of what strength, the valve will
open for a moment and leave on the ground beside the rail a coloured band from
30-50 cm. by 5-10 cm., thereby indicating where the defective parts of the rail
or way occur.

Improvements in Apparatus or Devices to be Applied to Railway
Carriages for Marking Defective Parts in the Rails or Way.
A. communication by GUSTAV MACK, of Nuremberg, Bavaria, in the Empire of
Germany, Royal Superintending Engineer.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street,
Manchester, both in the County of Lancaster, and 323, High Holborn, in the
County of Middlesex, 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 :-
This invention has for its object an improved apparatus or device to be applied
to railway carriages for marking defective parts in the rails or way.
On the accompanying drawings:-
Figure 1 is a longitudinal view of the railway carriage fitted with the device.
Figure 2 is a section on the line A B of Figure 1.
Figure 3 is a longitudinal section on the line C D of Figure 4, together with a
side view of a

page_text: Figure 4 is a view of the lead block, hereinafter described, from below.
Figure 5 is a view of the lead block from above.
Figure 6 shows details of the valve; and
Figure 7 shows details of the contact device.
On the flange F of the shackle of the spring, a strip is firmly attached by
means of two screws d; on this strip or plate b, there is a lead block a of about
7 kilogrammes in weight, which is attached to a guide bar ee¹; the latter is capable
of being turned outwards on an axis c, see Figure 3.
Owing to the shocks given to the springs when running over loose or uneven
places in the railway track, the lead. block is lifted upwards about 1 to 15 milli-
imetres. This lifting is accelerated and increased by a spiral spring arranged in
the interior of the block.
m
The movement of the weight. is transferred to. the movable elbow leverf by
means of the set screws ell and f', Figure 3. A space for play of about 4—6 18
left between these set screws, so that the numerous small and unimportant shocks
and vibrations do not operate on the apparatus.
The movement (lifting) is conveyed to the connecting rod g, Figures 3 and 5, by
means of the elbow lever f, and from this rod g to the elbow lever h, Figure 1,
which latter then at once lifts and opens the valve i. This is connected by means
of an india rubber tubing k, Figures 1 and 2, with a reservoir l, placed at a higher
level, which contains a diluted solution of aniline colour, such, for instance, as red
or blue. At each considerable shock during the journey, the valve is opened for a
moment and the liquid flows from the same, so that, at the point where the shock
is caused, a streak of colour remains on the ground beside the rail. In order to
prevent the valve closing too quickly, an air pressure brake in the form of a
bellows m m is arranged in combination with the above described apparatus, which
acts on the lever e e' of the lead block. In consequence of this, the lead block can
not fall back suddenly on to its seat but only gradually, so that the discharge from
the valve continues for a longer time and thereby a longer and more clearly
visible coloured streak remains on the ground (sleepers) beside the rail (say 3 to
2 metres.
An electrical contact device may also be placed at a suitable height above or on
the jolting apparatus over ff', and may be connected by means of wires with a dry
battery situated inside the carriage and a bell, see Figure 7. This latter sounds
at each considerable shock, so that the person in charge has his attention at once
drawn, by his sense of hearing also, to the defective places and can look out at
the same without there being any necessity to keep his gaze constantly on the
track.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, 1 declare that what I claim is :-
1. An apparatus or device to be applied to railway carriages for marking
defective spots in the permanent way, consisting in the arrangement of a lead
block a resting loosely ou the shackle of the springs and movable outwards, which,
at each shock, is thrown upwards and the motion of which is transferred by means
of a suitable connection in such a way to a discharge valve i connected with a
reservoir, placed at a higher level, that a jet of coloured liquid is poured at once
from the valve in proximity to the point in the rails which causes the shock,
substantially as hereinbefore described.
