Improvements in Securing Rails to Sleepers and in Rail Joints.
I, JOSEPH TRIPPETT, of the Standard Steel Casting Works, Coleridge Road,
Attercliffe, Sheffield, in the County of York, Steel Manufacturer, do hereby
declare the nature of my said invention to be as follows:-
-
The object of my invention is to provide a simple, and effective appliance for
securing railway or tramway rails to metallic sleepers, which appliance can by a
slight modification be likewise employed for fishing the ends of two rails together
as well as securing them to the sleeper.
Although my invention is applicable to various sections of rails, it is more
particularly applicable for securing rails of flat bottom section to rolled or pressed
metallic sleepers.
I carry out my invention in the following manner.
I then
In a metallic sleepers of channel section I cut, punch or otherwise form,
four transverse slots extending nearly the whole width of the sleeper clear of
the flanges on each side, two of the slots being placed at or near each end of the
sleeper, the outermost slots being made the widest and the space between the
two slots being a little wider than the bottom flange of the rail which is to be laid
on the said sleeper. I then pass through these slots from the underside of the
sleeper the flanges of a channel shaped clip, one flange of such clip being deeper
than the other. The deepest flange I pass upwards through the slot furthest from
the end of the sleeper, and the shortest flange I pass upwards through
the slot nearest the end of the sleeper. Having been so passed through
the slots in the sleeper I then press or close down by hydraulic power, hammering
or otherwise the shortest flange of the clip on to the top of the sleeper.
place a mandrill, which is of the same section as the bottom flange of the rail which
is to be used on the sleeper, so that one edge of the mandrill rests between the edge
of the turndown flange of the clip and the vertical flange of the clip which has not
yet been turned down, but as soon as the mandrill is in position I close this
remaining flange of the clip down upon the mandrill either by hydraulic power,
hammering, pressing or other convenient means so that when the mandrill is
withdrawn a clip will have been formed to receive one side of the flange of the rail
which is to be used on the sleeper, the opposite edge of the flange of the rail when
in position being in line with the edge of the clip which was first turned down
close to the sleeper. This outer flange of the rail I then secure by means of an
outside tongue or clip, one end of which is bolted to the sleeper. This clip may
be rolled of a special section so that the part which is bolted to the sleeper will be
thicker than the portion which clips the rail. In some cases I form this tongue
or clip by folding a piece of spring steel so that the portion which is of two
thicknesses carries the bolt by which it is secured to the sleeper, and the portion which
is of one thickness forms the tongue or clip which secures the flange of the rail.
In some cases the first mentioned tongue or clip which I pass through the slots

performed, to be particularly described and ascertained, in and by the following
statement:
The object of my invention is to provide a simple and effective appliance for
securing railway or tramway rails to metallic sleepers, which appliance can by a
slight modification be likewise employed for fishing the ends of two rails together
as well as securing them to the sleeper.
Although my invention is applicable to various sections of rails, it is more
particularly applicable for securing rails of flat bottom section to rolled or pressed
metallic sleepers.
My invention will be better understood on reference to the accompanying sheet
of drawings, in which,
Fig. 1, is a plan of one end of the metallic sleeper showing the slot.
Fig. 2, is the same after the clip has been secured.
Fig. 3, is the same after the rail has secured by the clips.
Fig. 4, is a section taken through the centre of the sleeper longitudinally.
Fig. 5, is a view of an alternative form of the outside tongue or clip.
Figs. 6, 7, 8 & 9, are similar views of a modification in the arrangement and
form of the clips.
Fig. 10, is à further modification in the form of the clips.
The same letters refer to similar parts throughout the several views.
I carry out my. invention in the following manner.
In a metallic sleeper, A, of channel section I cut, punch or otherwise form,
four transverse slots extending nearly the whole width of the sleeper clear of the
flanges on each side, two of the slots, B, C, being placed at or near each end of
the sleeper, the outermost slots, B, being. made the widest and the space between
the two slots being a little wider than the bottom flange of the rail, D, which is
to be laid on the said sleeper. I then pass through these slots from the underside
of the sleeper, the flanges of a channel shaped clip, E, one flange of such clip being
deeper than the other. The deepest flange I pass upwards through the slot, C,
furthest from the end of the sleeper, and the shortest flange I pass upwards through
the slot, B, nearest the end of the sleeper. Having been so passed through the
slots in the sleeper, I then press or close down by hydraulic power, hammering,
or otherwise, the shortest flange of the clip on to the top of the sleeper. I then
place a mandrill, which is of the same section as the bottom flange of the rail, 1),
which is to be used on the sleeper, so that one edge of the mandrill rests between
the edge of the turndown flange of the clip, and the vertical flange of the clip
which has not yet been turned down, as shewn by the dotted line Fig. 4, but as soon
as the mandrill is in position, I close this remaining flange of the clip, down upon
the mandrill, either by hydraulic power, hammering, pressing, or other convenient
means so that when the mandrill is withdrawn a clip will have been formed to
receive one side of the flange of the rail which is to be used on the sleeper, the opposite
edge of the flange of the rail when in position being in line with the
edge of the clip which was first turned down close to the sleeper. This outer
flange of the rail I then secure by means of an outside tongue or clip, F, one end
of which is bolted to the sleeper. This clip may be rolled of a special section so
that the part which is bolted to the sleeper will be thicker than the portion which
clips the rail, as shown in Fig. 5. In some cases I form this tongue or clip by
folding a piece of spring steel, F1, as shewn in Fig. 4, so that the portion which is
of two thicknesses carries the bolt, G, by which it is secured to the sleeper, and the
portion which is of one thickness forms the tongue or clip which secures the flange
of the rail. In some cases the first mentioned clip, E, which I pass through the
slots in the sleeper I further secure to the sleeper by means of a countersunk
rivet or rivets, H, H.
When required for fishing the ends of two rails together, as well as securing
them to the sleeper, I form the vertical flange of the channel shapel clip, E,
previously described, deep enough to cover the flange of the rail, D, on one side and

illustrated in Fig. 10, with the fish or joint bolts J, J, in the manner and for the
purposes substantially as herein described and illustrated.
