PROVISIONAL SPECIFICATION.
An Improved Metallic Sleeper with Rail Fastening Devices.
We, ANTONIUS LOLLING of Kleine Gärtnerstrasse 127, Altona, Germany,
Gentleman, and CHRISTIAN PRIGGE of Pilatuspool 30 Hamburg, Germany,
Engineer, do hereby declare the nature of this invention to be as follows:-
1
This invention relates to an improved construction of transverse metallic sleeper
with rail fastening devices for securing rails in position thereon, each of these
devices comprising a pair of jaws or clips (hereinafter called jaws) that are arranged
to slide upon the top of the sleeper in suitable guides and are forced by screws with
nuts into close contact with the foot of the rail so as to securely hold the same to
the sleeper.
In the accompanying drawings,
Fig. 1 is a front elevation,
Fig. 2 a plan; and
Fig. 3 a longitudinal section on the line ab of Fig. 2, of part of a transverse
metal sleeper with rail fastening according to this invention.
Figs. 4 and 5 are cross sections on the lines c d and e f respectively of Fig. 1.
The sleeper A is made of approximately I form in cross section, with a bread
foot or base having downwardly inclined wings. This sleeper near each end is
provided with a rail fastening device comprising two jaws or clips D D each formed
to bear against the foot of the rail, and provided with a screw threaded part D',
furnished with a screw nut E. Secured to the sleeper at each side of the rail, it
may be by rivetting, are guides B and C for the corresponding jaw D and its
screw D. The hole through the guide B corresponds in cross section to the form
of the jaw D to work therein see Figs. 3 and 4 but the hole through the guide C
can be made in the form of a recess as shewn in Fig. 5 to facilitate the insertion in
place and removal of the jaw D and screw D¹. When a rail has been laid in the
proper position upon the sleeper A between the pair of jaws D, it is secured in
place by screwing the nuts E towards and against the guide C until the jaws D
which are thereby moved endways and towards the rail, firmly hold the foot of the
rail on both sides, and press the same against the sleeper by reason of the curved
formation given to their forward parts which is made to correspond with that of the
foot of the rail.

In the drawings.filed with our Provisional Specification
Fig. 1 is a front elevation,
Fig. 2 a plan; and.
:
Fig: 3 a longitudinal section on the line ab of Fig: 2 of part of a transverse
metal sleeper with a rail fastening device according to this invention.
Figs. 4 and. 5 are cross sections on the lines c d and.ef respectively of Fig. 1.
The sleeper A is made of approximately I form in cross section, with a broad
foot or base having downwardly inclined wings. This sleeper near each end is
provided with a rail fastening device comprising two jaws or clips D D each formed
to bear against, the foot of the rail, and provided with a screw threaded part D',
furnished with a screw nut E. Secured to the sleeper at each side of the rail, it may
be by rivetting, are guides B and C for the corresponding jaw D and its screw Di
The hole through the guide B corresponds in cross section to the form of the jaw D
to work therein (see Figs. 3 and 4) but the hole through the guide C can be made
in the form of a recess as shewn in Fig. 5 to facilitate the insertion in place and
removal of the jaw D and screw D¹. When a rail. has been laid in the proper
position upon the sleeper A between the pair of jaws D, it is secured' in place by
screwing the nuts E towards and against the guide C until the jaws D which are
thereby moved endways and towards the rail, firmly hold the foot of the rail on
both sides, and press the same against the sleeper by reason of the curved formation
given to their forward parts which is made to correspond with that of the foot of
the rail...
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is :-
-
1. A transverse metallic sleeper made approximately of I form in cross section
with a narrow head and a broad foot having downwardly inclined wings and provided
with rail fastening devices each comprising a pair of jaws D having screw threaded
parts D' with nuts E the arrangement being such that a rail resting upon the
upper part of the sleeper can be firmly held both laterally and vertically by the
two jaws D which are caused to move along the upper part of the sleeper by
the screw nuts E, the jaws being retained in position relatively to the sleeper and
rail by guides B and C and the guides C being made open at the top substantially
as herein described for the purpose specified.
