Telegraph Posts, Railway Sleepers, and the like.
I, BROR OLOF VIKTOR HELLSTRÖM, of Norrköping, in the Kingdom of Sweden,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to the manufacture of posts and bars, especially telegraph
and telephone posts and railway sleepers of beton with an embedded iron framing, in
order to obtain a complete solidity and strength of such posts or bars. These posts
and bars, which become more resisting against bending and pressure than common
posts of wood have moreover the great advantage above wood posts, that they are not
affected by rot or decay.
In order to prevent the action of weather on the beton, the objects may be coated.
with a material that is not decomposed by air and water, as for instance asphalt, and
in order to render them lighter, they may either be made hollow, or the stone in the
beton may be replaced by a lighter material, for instance slag..
.
In the accompanying drawings three different modifiations of these posts, bars and
sleepers are illustrated. Figures 1 and 2 show longitudinal sections of two differently
arranged posts, Figures 3 and 4 are vertical and cross sections on an enlarged scale
of Figure 1 and Figures 5 and 6 are similar enlarged sections of Figure 2.
A, Figures 3 and 4 are four parallel solid iron bars running along the whole length
of the post and which form the principal part of the iron framing, which latter more-
over comprises a number of cross-pieces B passed on the bars A and placed at a cer-
tain distance from each other. Those cross pieces, which are inade of thin flat or
sheet iron not only contribute to a solid connection between the bars A, but by means
of their bent edges, projecting around the bars they also bind the outer layer of the
beton-mass, which is cast around the whole iron-framing.
In Figures 5 and 6 the bars are replaced by a single tube D, forming the core of
the post. On this tube, which eventually may be filled in the interior with cement
or any other suitable matter to make the same more resistant to bending, crosses E
are passed in the same way as the before named cross-pieces B, to hold the beton-
mass well together, and to make the same resistant to bending. In order that these
crosspieces or discs may better fulfil this purpose their outer ends are bent upwards
to an angle. The bars A shown in Figures 3 and 4 can of course be replaced by
tubes, and similarly the tube shown in Figures 5 and 6 can be replaced by a solid
iron bar.
Figures. 7 and 8 show the invention applied especially to railway-sleepers.
Figures 9 and 10 are longitudinal and cross-sections of the same on an enlarged
scale. Here the round irons are replaced by shaped or angle irons F and the bars
form a square frame-work completely embedded in the beton-mass with the junctions
under the places, where the sleepers repose. In larger sleepers two square frame-
works are used, whilst in smaller sleepers on the contrary only one or in some cases two

mass better together and to strengthen both square frame-works, they are provided
with flat irons G, the edges of which eventually are bent to an angle.

Improvements in Posts and Bars applicable for Telephone and
Telegraph Posts, Railway Sleepers, and the like.
I, BROR OLAF VIKTOR HELLSTRÖM, of Repslagaregatan 9, Norrköping, in the
Kingdom of Sweden, Engineer, do hereby. declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to the manufacture of posts and bars, especially telegraph and
telephone posts and railway sleepers of beton with an embedded iron fraining, in
order to obtain a complete solidity and strength of such posts or bars. These posts
and bars, which become more resisting against bending and pressure than common
posts of wood have moreover the great advantage above wood posts, that they
are not affected by rot or decay.
In order to prevent the action of weather on the beton, the objects may be coated
with a inaterial that is not decomposed by air and water, as for instance asphalt, and
in order to render them lighter, they may either be made hollow, or the stone in the
beton may be replaced by a lighter material, for instance slag.
In the drawings accompanying the Provisional Specification three different modifi-
cations of these posts, bars and sleepers are illustrated. Figures 1 and 2 show longi-
tudinal sections of two differently arranged posts, Figures 3 and 4 are vertical and
cross sections on an enlarged scale of Figure 1 and Figures 5 and 6 are similar
enlarged sections of Figure 2.
A, Figures 3 and 4 are four parallel solid iron bars running along the whole length
of the post and which form the principal part of the iron framing, which latter more-
over comprises a number of cross-pieces B passed on the bars A and placed at a cer-
tain distance from each other. Those cross pieces, which are made of thin flat or
sheet iron not only contribute to a solid connection between the bars A, but by means
of their bent edges, projecting around the bars they also bind the outer layer of the
betou-mass, which is cast around the whole iron-framing.
In Figures 5 and 6 the bars are replaced by a single tube 1), forming the core of
the post. On this tube, which eventually may be filled in the interior with cement
or any other suitable matter to make the same more resistant to bending, crosses-E
are passed in the same way as the before named cross-pieces B, to hold the beton-mass
well together, and to make the same resistant to bending. In order that these cross-
pieces or discs may better fulfil this purpose their outer ends are bent upwards to an
angle. The bars A shown in Figures 3 and 4 can of course be replaced by tubes, and
similarly the tube shown in Figures 5 and 6 can be replaced by a solid iron bar:"
Figures 7 and 8 show the invention applied especially to railway-sleepers. Figures 9
and 10 are longitudinal and cross-sections of the same on an enlarged scale: Here
the round iron's are replaced by shaped or angle irons F and the bars form a square
frame-work completely embedded in the beton-mass with the junctions under the
places, where the sleepers 'repose. In larger sleepers two square frame-works are used;
whilst in smaller sleepers on the contrary only one or in some cases two frame-works

together and to strengthen both square fraine-works, they are provided with flat
irons G, the edges of which eventually are bent to an angle.
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 :-
1. A structure of the kind described made of beton or the like, having an internal
metallic staying or bracing structure and anchors loosely applied thereto at suitable
distances from one another and consisting of flanged plates, for the purpose set forth.
2. A structure of the kind described made of beton or the like having an internal
metallic staying or bracing framing comprising frame members and anchors, each of
which latter consists of a flanged plate loosely applied to said frame members at suit-
able distances from one another for the purpose set forth.
3. A structure of the kind described made of beton or the like having an internal
metallic staying or bracing framing composed of longitudinal girts, connecting brace
members secured thereto, and anchors, each of which latter is composed of a flanged
plate loosely applied to the longitudinal girts at suitable distances from one another
for the purpose set forth.
