I, RUDOLPH DOLBERG of Rostock in the Grand-Duchy of Mecklenburg, German
Empire, do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in the connection of the rails of field-railways,
and consists in the use of two fish-plates a and c; the plate a is fastened to the end of
one of the rails of a pair, and the plate c to the opposite rail of the next pair; the
plate a is furnished with a pin b, and the plate c is bent outwards as shown in the
annexed drawing, so that by means of a side movement, the two pair of rails are
jointed together the operation of jointing the rails is shown in fig. 1.
The rails g ghi are fastened to the sleepers f in the usual manner by means
of bolts, wood screws, or spikes and each pair distinct in itself. The left-hand rail of
each pair is furnished on the inside with a fish-plate a which projects beyond the end,
of the rail, and provided with a pin b; while the right-hand rails g¹ h² are provided
with a plate c, at the opposite end, which plate is bent outwards as shown at d. The
left-hand rails hi are also provided with a slot, into which the pin / fits. In
jointing the pair c with pair B, it is necessary to place e in such a position so that
the pin b, may fasten into the hole in the adjoining rail h, and then brought round so
that the rail i comes against the plate c and pushed into place. The pin b insures
against the rails coming asunder in a longitudinal direction, and the plates a and e
against any side movement.
The same result can be obtained by placing the plates c c¹ on the inside of the
rails hg, opposite the plates a. But this arrangement could only be applied to
light field-railways with rails having broad heads.
The above rail joint although a simple and cheap arrangement, prevents the rails
from being drawn asunder and also against them being unjointed by vertical
pressure.

page_text: I, RUDOLPH DOLBERG of Rostock, in the Grand-Duchy of Mecklenburg, German
Empire, manufacturer 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 improvements in the manner of jointing the rail sections of
field railways together and consists of pins and a spring joint.
In order to make my invention clear I refer to the drawing, which was left with
the provisional specification and in which similar letters denote similar parts throughout
the different figures.
Fig. 1 shows a top view of the improved joint.
Fig. 2 shows the same but on a larger scale.
Fig. 3 shows a side view of fig. 2.
My invention consists in the use of two fish-plates a and c; the plate a is fastened
to the end of one of the rails of a pair, and the plate c, to the opposite rail of the next
pair; the plate a is furnished with a pin b and the plate c is bent outwards as shown
in the drawing, so that by means of a side movement, the two pair of rails are jointed
together. The operation of jointing the rails, is shown in fig. 1.
The rails, g gh hii are fastened to the sleepers ff in the usual manner by
means of bolts, wood screws, or spikes, and each pair distinct in itself. The lefthand
rail of each pair is furnished on the inside with a fish-plate, a which projects beyond
the end of the rail, and provided with a pin b; while the righthand rail, gh¹ are
provided with a plate c, at the opposite end, which plate is bent outwards, as shown
at d. The lefthand rails g h i are also provided with a slot, into which the pin 6 fits.
In jointing the pair C with pair B it is necessary to place C in such a position, so that
the pin 6 may fasten into the hole in the adjoining rail and then brought round so
that the rail i comes against the plate c, and pushed into place. The pin 6 insures
against the rails coming asunder in a longitudinal direction, and the plates a and c
against any side movement.
The same result can be obtained by placing the plates cc' on the inside of the
rails ¹¹g¹, opposite the plates 4 a. But this arrangement could only be applied to
light field-railways with rails having broad heads.
The above rail joint, although a simple and cheap arrangement, prevents the rails
from being drawn asunder and also against them being unjointed by vertical
pressure.

page_text: Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed, I declare that what I
claim is:
In joints of rails for field-railways the plates a and c, the plate a being fastened to
the end of one rail of a pair and the plate c being fastened to the opposite rail of the
next pair, the plate a being provided with a pin b and the plate e with a deflection d,
substantially and for the purpose as described.
