I, EDUARD SOHмIDт, railway-inspector, residing at Zimmersrode, Kingdom of
Prussia, do hereby declare the nature of this invention to be as follows:-
My invention relates to the railway-sleepers described in the specification of the
British patent No. 2166, A.D. 1886, the said sleepers being made of two flanged rails
placed with their webs horizontal and connected together by suitable means, and the
improvement consists in constructing the sleepers of two double-headed rails or chair-
rails, or of a single rail whether double-headed or flanged.
In case two double-headed rails are employed to constitute the sleeper, and if the
track-rail to be carried by the same has a like form, the sleeper-rails may be connected
together by means of the chairs supporting the said track-rails, the requisite bearing
surfaces for the chairs being formed upon the sleeper-rails by cutting away portions
of the heads of the same.
With broad-footed or flanged irack-rails the connection of the sleeper-rails with
each other and with the track-rails is obtained in like manner as described in the
specification referred to abovo, i.e. by means of cross-plates forming bed-plates for
the track-rails, of clamping-plates bearing on the flanges of the track-rails and of
bolts passing through the sleeper-rails, the bed-plates and the clamping-plates.
For narrow gauge railways, tram-ways and others, the sleepers may each be made
of a single rail, being either double-headed or flanged, the said rail also having
portions of both heads, or of the head and the foot (as the case may be) cut away so
as to present fair bearing surfaces for the track-rails or the chairs thereof, and in the
case of broad-footed track-rails these may be fastened down on the sleeper-rail by
clamping-plates and bolts without the use of bed-plates.

page_text: 1. EDUARD SCHMIDT, railway-inspector, residing at Zimmersrode, Kingdom of
Prussia, 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 the railway-sleepers described in the specification of the
British patent No. 2166, A.D. 1886, the said sleepers being made of two flanged rails
placed with their webs horizontal and connected together by suitable means, and the
improvement consists in constructing the sleepers of two double-headed rails or chair-
rails, or of a single rail whether double-headed or flanged.
In case two double headed rails are employed to constitute the sleeper, and if the
track-rail to be carried by the same has a like forin, the sloeper-rails may be connected
together by means of the chairs supporting the said track rails, the requisite bearing
surfaces for the chairs being formed upon the sleeper-rails by cutting recesses into
one or both heads of the same.
On the annexed sheet of drawings the left-hand portions of Figs. 1 and 2 show in
elevation and plan, and Fig. 3 in an end-view, a sleeper and track-rail of this kind,
the sleeper being composed of the two double-headed rails a a connected together by
means of the chair and the bolts c.
If the sleepers are designed to carry broad-footed or flanged track-rails, as shown
by the right-hand portions of Figs. 1 and 2, and by Fig. 4, the connection of the
sleeper-rails a a with each other and with the track rails c is obtained in like manner
as described in the specification referred to above, that is to say, by means of cross-
plates sunk into the heads of the sleeper-rails and forming bed-plates for the track-
rails, of clamping-plates & bearing on the flanges of the track-rails, and of bolts e
passing through the sleeper-rails, the bed-plates and the clamping-plates.
For narrow gauge railways, tram-ways and others, the sleepers may each be made
of a single rail, being either double-headed or flanged, the said rail also having
portions of both heads, or of the head and the foot (as the case may be) cut away,
so as to present fair bearing surfaces for the track-rails or the chairs thereof, and in
the case of broad-footed track-rails these may be fastened down on the sleeper-rail
by clamping-plates and bolts without the use of bed-plates. Thus Figs. 5, 6 and 7
represent a sleeper made of a single flanged rail a and carrying the flanged track-
rails c, the latter being secured to the rail a by the clamping-plates & and the bolts e.
Preferably the recesses cut into the head and the flange or the two heads of the
sleeper-rail, are made of such width and the outer clamping-plates of such size that
the latter will abut against the outer end surface of the recesses, in order to prevent
the track-rail from shifting outward. The inner clamping-plates may be arranged in
like manner, but as the track-rails are not apt to shift inward, the inner clamping-
plates any he made narrower so that they will pass in between the head and the
flange, or the two heads, of the rail a, as shown by the right-hand portion of Fig. 6.

page_text: Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is :
1. A railway sleeper consisting of two double-headed rails a placed in juxtaposition
with their webs horizontal, and connected together by chairs for cross-plates b and
by bolts e, the said chairs or cross-plates being placed in recesses cut into one or
both heads of each of the rails a, substantially as hereinbefore set forth.
2. A railway sleeper consisting in a single rail a, either double headed or flanged,
placed with its web horizontal, and the heads, or the hand and flange whereof are
provided with recesses for receiving the track-rails c or the chairs that carry them.
