Complete Specification Accepted, 16th Nov., 1888
I, RUDOLPH DOLBERG of Rostock in the Grand-Duchy of Mecklenburg, German
Empire, manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in jointing the rails of field railways; and
consists in the employment of hooks and pins, as may be seen from the annexed
drawing and fully described in this specification.
The two rails a a¹ (fig. 1) of a pair, are fastened to the sleeper b, by means of the
flanged chairs d d' and held fast by the bolts e e¹ and kept at the proper gauge, at the
other end by the tie rod c; the next pair of rails rest with their ends also on the
chairs d d¹.
The rails are prevented from moving sideways by means of the flanges on the
chairs d d' and the hook g.
The hook g (fig. 5) which is riveted to the ends of the rails ff1, fastens on the pin h,
which is riveted into the ends of the rails d d'; whereby the rails are prevented from
moving in a vertical direction. In jointing one pair of rails, to another pair, the
rails ffare lifted, at the opposite end to which the hooks g g¹ are, in order to let the
hook g pass between the rail-flange and the pin h; as shown in fig. 3. When the rails
are lowered in place, the hook g fastens on the pin h, so that the rails cannot come
asunder.
The hooks g, are tapered at the point as well as at the sides, in order to facilitate the
jointing and unjointing of the rails.

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 jointing the rails of field-railways, and 5
consists in the employment of hooks and pins, as may be seen from the drawing
lodged with the provisional specification and fully described in this specification.
Fig. 1 is an end view of a rail section.
Fig. 2 is a top view of a section showing the joint with the neighbouring
section.
Fig. 3 shows the way to hook or joint the rail-sections together.
Fig. 4 shows a top view of the join on a larger scale.
Fig. 5 shows a side view of the same on the same scale.
The two rails a a¹ (fig. 1) of a pair are fastened to the sleeper b by means of the
flanged chairs d d' and held fast by the bolts e e¹ and kept at the proper gauge at
the other end by the tie rod c; the next pair of rails rest with their ends also on the
chairs d d.
The rails ffare prevented from moving sideways by means of the flanges on the
chairs d d and the hook
9.
The hook g (fig. 5) which is riveted to the ends of the rails ff' catches on the
pin h, which is riveted into the ends of the rails a a', whereby the rails are prevented
from moving in a vertical direction. In jointing one pair of rails to another pair, the
rails are lifted, at the opposite end to which the hook g g are in order to let the
hooks g g pass between the rail flange and the pins h h as shown in fig. 3. When the
rails are lowered in place, the hooks g g fasten on the pin h h so that the rails cannot
come asunder.
The hooks g g are tapered at the points as well as at the sides, in order to facilitate
the jointing and unjointing of the rails.
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 curved and tapered hooks g g fastened to the
ends of one pair of rails and hooking on to pins fastened on the next pair of rails,
substantially and for the purpose as described.
