The Universal Inventors and Patentees Financial Company Limited 30 Finsbury
Pavement London E.C: "IMPROVEMENTS IN THE PERMANENT WAY OF RAILWAYS
A communication to me from abroad by Fridolf Schauman Railway Director in
Sweden
The object of this invention is to obtain a durable elastic and safe permanent way,
it consists in the employment of stone or concrete sleepers, with washer plates of
compressed or prepared cork as an elastic medium between the rails and the said
stone or concrete sleepers, the said rails and compressed or prepared cork washer
plates being fixed to the stone or concrete sleepers by means of bolts and nuts, and
spring clip plates.
The stone or concrete sleepers are laid in the ballast of the road, and are. cach
furnished with four bored or cast bolt holes, through which pass wrought iron bolts
with hooks or heads at their lower ends, and nuts at their screwed upper ends.
The compressed or prepared cork washer plates are placed at or near the edges of
the stone or concrete sleepers and so that the aforesaid bolts also pass through holes
formed in them corresponding to the holes in the said sleepers.
The rails which are of a flat bottomed section are laid on these compressed or
prepared cork washer plates and are secured thereto and to the sleepers by spring
clip plates of suitable form and dimensions, which are adapted to bear at one eud on
the upper side of the foot of the rail and at the other end on the compressed or
prepared cork washer plates the aforesaid bolts pass through holes in such spring
clip plates and the nuts of the said bolts when tightened up bear upon the said.
spring clip plates and hold the rails, the cork washer plates, and the stone or concrete
sleepers firmly together.
The desired width between the rails is secured by iron cross ties.
•
By reducing or increasing the thickness of the compressed or prepared cork
washer plates the road can readily be adjusted.

LORENTZ ALBERT GROTH K.G.V Civil Engineer and Managing Director of
The Universal Inventors and Patentces Financial Company Limited 30 Finsbury
Pavement London E.C. IMPROVEMENTS IN THE PERMANENT WAY OF RAILWAYS
A coinmunication to me from abroad by Fridolf Schauman, Railway Director in
Sweden.
P
The object of this invention is to obtain a durable, elastic and safe permanent way
and it consists in the employment of stone or concrete sleepers with washer plates
of compressed or prepared cork as an elastic medium between the rails and tho said
stone or concreto sleepers, the said rails and compressed or prepared cork washer
plates being fixed to the stone or concrete sloepers by means of bolts and nuts and
spring clip plates.
In the accompanying drawing Fig 1 shows a cross section of the stone sleeper the
compressed or prepared cork washer plate, the screw bolts with the nuts and spring
clip plates and the rail: Fig II shows a plan of Fig I. Figs III and IV show
respectively in elevation and plan the application of this invention to the ordinary
chair and rail. Fig V shows an elevation of a piece of permanent way constructed
in accordance with the said improvements Fig VI a plan and Fig VII a cross
section of the same and Figs VIII, IX and X an elevation plan and cross section of
a similar piece of permanent way but with another form of stone or concrete
sleeper. ⚫
The stone or concrete sloepers a are laid in the ballast of the road and are each
furnished with four bored or cast bolt holes through which pass wrought iron bolts c
with hooks or heads at their lower ends and nuts c at their screwed upper ends.
The compressed or prepared cork washer plates b are placed at or near the edges of
the stone or concrete sleepers d and so that the aforesaid bolts c also pass through
holes formed in them corresponding to the holes in the said sleepers. The railsf
which are of a flat bottomed section are laid on these compressed or prepared cork
washer plates b and are secured thereto and to the sleepers by spring clip plates d
of suitable form and dimensions which are adapted to bear at one end on the upper
side of the foot of the rail, and at the other end on the compressed or prepared cork
washer plates b, the aforesaid bolts c pass through holes in such spring clip. plates &
and the nuts e of the said bolts when tightened up bear upon the said spring clip
plates and hold the rails f, the cork washer plates b and the stone or concreto
sleepers & firmly together.
The compressed or prepared cork washer plates and stone or concrete sleepers
are also applicable to the ordinary chair and rail as shown in Figs III and IV
f being an ordinary rail, d the chair, h the wooden wedge b the cork washer plate,
d the stone sleeper, c the bolts, and e the nuts.
In this case the spring clip plates are dispensed with

The desired width between the rails is secured by iron cross ties g
By reducing or increasing the thickness of the compressed or prepared cork
washer plates 6 the road can readily be adjusted
Having now described the nature of the said invention and the manner in which
the same is to be carried into effect I would have it understood that what I
claim is
In the construction of the permanent way of railways the employment of stone

page_text: or concrete sleepers with compressed or prepared cork washer plates interposed
between such sleepers and the rail, the said rail and the compressed or prepared
cork washer plates being secured to the said stone or concreto sleepers by screw
bolts and nuts and spring clip plates, the whole arranged and combined as herein-
5 before described and illustrated in the drawings hereto annexed and for the
purposes set forth. In witness whereof I the said Lorentz Albert Groth have
hereunto set my hand and seal this twenty-fifth day of January in the year of
Our Lord One thousand eight hundred and eighty three.
