of York Patent Agent and Consulting Engineer "IMPROVEMENTS IN IRON
PERMANENT WAYS APPLICABLE FOR RAILWAYS AND TRAMWAYS. Communicated
to me from abroad by C. Verhoesen, Chief Engineer of the Niederlandische Central
Railway Company Utrecht
I employ an ordinary iron sleeper, upon which is a wrought iron chair, secured
to the sleeper by bolts, nuts, cramps, and safety plates, the safety plates are slit, and
bent upwards to prevent the nut from working loose, the rail is secured to the
chair, by dogs, or cramps, on each side resting on the rail at one end, and in a recess
in the chair at the other end, and secured midway by a bolt passing through the
whole; for preventing direct pressure, I use a conducting angle or plate, its foot
resting against the bottom of the rail, its upper part standing out from the rail
forms a groove for the wheel flanges; a collar or bush through which a bolt passes
secures it in position at points where fish plates are required, spaces are cut away
in the conducting angle. Or for street tramways the rail may be secured direct to
the wrought iron sleeper by the bolts, nuts cramps and safety plates as before
described. The conducting angle or plate is intended to procure an energetic
resistance of the rails against. the lateral pressure and so assist the necessary
stability and firmness of the track.

Such being the nature and object of this my said invention in order that the
same may be fully understood I have hereunto annexed two sheets of drawings
illustrative thereof, and have marked the same with figures and letters of reference:
similar letters refering to similar parts throughout the several views.
DESCRIPTION OF DRAWINGS.
Fig 1. Sheet I demonstrates how the rail A is joined on one hand with the
conducting angle P; through the bolt B by which means the collar a, prevents the
direct pressure when the nut of the bolt is screwed on, while on the other hand
the rail-A appears sufficiently firmly joined to wrought iron chair S through the
cramps K and K¹, which are joined one to the other by the bolts C; the chair S
rests on an ordinary iron sleeper Q, and is joined to it by the screws S and S'
which latter are at the same time, in a position to press the safety, plates M and M
firmly
the foot of the chair, the slit and bent up strip of the safety plate W
prevents by its position the nut of the screw from turning, the bolt B rests in á
box H in order to save it from exterior influences.

The side view of Fig. 3 shews the hole cut in the conducting angle P for the
cramp K and the chair S further the connection by screws of the safety plate with
the sleeper and finally the lateral section of this latter.
By the upper view of Fig. 4 results the fishing at the joints, of the rails the
Situation of the supported joint on the iron chair S, and the simultaneous connection
of the conducting, angle P, with the rail.,,

Fig. 5, shews the conjunction by fish plates of the joints of the conducting
angles.
Fig. 1. Sheet 2 shews the direct connection of the rail with the sleeper further-
more by using the conducting angle.

page_text: By Fig. 2 will be shewn the lateral section of the rail; by Fig. 3 the section of
the rail, with the connection by fish plates; by Fig 4 the lateral section of the fish
plates; while Fig. 5. shews the coupling screw for the connection of the fish plates;
and Fig. 6 the situation of the safety plates. Fig. 7 shews the disposition of the
holes in the fish-plates
Fig 8 the disposition of the set of tracks.
For artificial street pavement, high roads etc. and for a traffic carried on by
means of steam engines, the use of the iron chair and sleeper recommends itself;
this is intended for procuring an energetic resistance of the rails against the lateral
pression of the pavement and so to obtain the necessary stability of the set of
tracks.
The direct fastening of the rail on the sleeper is more suitable for a traffic carried
on by horses, and it allows the use of any kind of bedding.
Having thus fully described and particularly ascertained the nature and object of
this my said. invention, and the manner in which the same may be performed, I
would have it understood that what I claim as the invention to be secured to me
by the hereinbefore in part recited Letters Patent is.―
1. The connection of the rail with the conducting angle P which forms at the
same time the groove for the wheel as shewn illustrated and described
2. The combination of the rail with the chair S and the sleeper Q as shewn
illustrated and described.
.3. The direct fastening of the rail on the sleeper Q as shewn, illustrated and
described
In witness whereof I the said John Edward Walsh have hereunto set my
hand and seal this eighth day of June in the year of our Lord one thousand
-eight hundred and eighty three
