Apparatus for Preventing Railway Rolling Stock Leaving the Lines
in Collisions.
I, GOTTLIEB KIMMICH, of 9 Mittlere Beutau, Esslingen of Neckar, Germany,
Mechanician, 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 :-
It is a well known fact, that, when two trains run against each other, or when one
of them runs against an obstacle, the most serious injuries to the persons conveyed
in the trains are caused by the carriages being piled up, "de-railed," or over-
turned. To prevent this, is the object of this invention, and this object is attained
principally by the automatic and instantaneous operating of gripping appliances
attached to the vehicles, as soon as the danger in question arises.
The subject of this invention is a tong-like appliance attached to the vehicle,
which grips the rail-heads, upon a mechanism, as a lever arrangement, being
actuated by a buffer; whereby the axles of the vehicle attend to the closing of the
gripping appliance, though the locking of sane may also be performed by the
buffer alone.
The annexed drawings shew the subject of the invention, viz. :
Figure 1 is a longitudinal section through the vehicle, at - of Figure 2.
Figure 2 is a plan of the vehicle with the bottom removed.
Figure 3 is a partial cross section and partial elevation of the vehicle.
Figure 4 is an elevation of the gripping appliance in the longitudinal direction
of the vehicle; and
Figure 5 the side view of the gripping appliance.
Figures 4 and 5 are represented on an enlarged scale.
In the case represented, there are a pair of gripping appliances fitted near one
of the pairs of wheels, in such a manner that one of them is above each rail.
But several pairs of such gripping appliances may be fitted at any places desired.
According to Figures 4 and 5, each gripping appliance consists of two vertical
arms a, which together act as tongs. But in order that the lower ends of same
forming the jaws may, on the one hand, as a general matter, stand so far above
the rails that it is possible to pass switches, and places on the track provided with
guard-rails, and on the other hand, that they may also be able to grip the web of
the rails, the following arrangement has been made.
Near their lower ends the arins a are each provided with a pin b, which works
in the groove c¹ of a cramp c, the distance of which from the upper edge of the
rail is fixed. These grooves c are arranged in a vertical direction in their
upper portions, but in their lower portions they approach each other. If, there-
fore, both arms a of the tongs move downwards at the same time, and if the
cramp c is in a corresponding position, it follows that the lower ends of the arms a
of the tongs, which e.g. may be provided with a check d, grip the web of the
rail in question, the head of the rail thus preventing the rising of the vehicle.
The downward movement referred to, of the arms a of the tongs, is produced
by means of a horizontal bolt f, the ends of which are connected with same by
joints, and which (the bolt) is, by preference, provided with a roller f¹and fits
into the angular groove 9 of a horizontal rod g. If the latter is pushed one
way or the other, either of the two sides of this groove g¹ operates. In either
case, however, the gripping appliance will act and the track-rail will be seized.

page_text: The connection between this gripping appliance and the vehicle is, in the case
represented, produced by rods h and h¹ respectively extending from the cramp c to
the axle-boxes i, Figure 1. But besides this, a connection may also be formed
between the cramp c and the frame k or the body 1, by preference by means of
coir-ropes. By preference, the arms a of the tongs are adapted to fit into
hollows of the cramp c. The upper end fits in a hanger m attached to frame k,
and provided with a slot m', so that it may be prevented from moving in the
longitudinal direction of the carriage. The two rods g, which are forced into
the mean position by two springs n (Figures 1 and 2) are connected with each
other by e.g. 4 cross bars o. The latter at the same time serve to connect rods p,
from
which on the one hand surround the hubs g, in order to prevent the rods
attaining a downward motion. To the ends of rods p, which are turned outwards,
a further cross bar is attached, which, together with one of the rods o serves for
connecting a buffers in the middle of the carriage. If one of these buffers s
strikes an obstacle, or a second buffer, the rods g will likewise be pushed along in
the longitudinal direction. By this the cogs g² of arnis g of these rods
gear into a cog wheel g' on the hub g, and then the axles perform the locking of
the gripping appliance in the manner described, but the locking of the gripping
appliance may, under certain circumstances, be performed by the buffers alone.
will
In the same manner as the locking of the gripping appliance is performed by
means of the axle on the hubs of the wheel, the brake-blocks t of a set of wheels
or all the sets of wheels of a carriage may be actuated automatically. For
instance, this can be done by having the rods or, lying to the left in Figures 1
and 2, reaching through slots in the hanging guides u, so that the latter
perform a pendulating motion when the rods g are pushed along. Now the bars w
bearing the brake-blocks t have arms v driven onto them; when the banging
guides u perform that motion, the eye v¹, of the arm v. which approaches the
circumference of the wheel, gears into cogs of hubs q and the brake is auto-
matically actuated.
In order to produce a gripping connection between the vehicles and the rails
before a collision should occur, a rod may be attached, in any suitable known
manner, to the locomotive engine, or to the last carriage, which rod extends beyond
the buffers and actuates the gripping appliances when striking an obstacle. This
rod may also be provided with a small trolley preceding the engine.
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 1
claim is
-
1. For preventing the piling up, de-railing and overturning of railway rolling
stock, an automatic appliance, consisting of gripping devices on the vehicles,
which, by means as or substantially as described, upon an obstacle or the
preceding vehicle being struck, are caused to grip the track-rail: operating
substantially as set forth.
2. In apparatus of the kind herein described, the means of actuating a brake
to relieve the rail gripping appliances comprising a longitudinal movable rod,
as g, operating substantially as set forth.
3. The automatic appliances for preventing railway rolling stock leaving the
rails, set forth with reference to and shewn in the drawings.
