Year: 1884

page_text: I BOLESLAW VOGDT of Vienna in the Austro Hungarian Empire Engineer, do
hereby declare the nature of my Invention for IMPROVED SYSTEM OF ENTIRELY
METALLIC PERMANENT WAY FOR RAILWAYS and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:
This improved system of entirely metallic permanent way for railways iɛ
represented in the annexed Drawings as follows:
Fig. 1 is a transverse section of an iron support with the rail fixed on the same;
Fig. 2 is a side elevation of a bolt for jointing the foot of the rail with the
support;
Fig. 3 is a plan of said bolt.
Fig. 3 is an isometric view of a fastening wedge for said bolts.
Fig. 4 is a transverse section of the complete way.
Fig. 5 is a plan of one of the iron supports, to be placed longitudinally below the
rail.
Fig. 6 shews the plan of a transverse iron support with the rail fixed on the
same.
Fig. 7 is a transverse section of a jointing bolt.
Fig. 8 is a side view of a bolt as used for fixing on the rail the continuous
fish C.
Fig. 8ª shows a bolt serving to fix on both sides of two meeting rails the double
fishes.
Fig. 8° and 8ª show two forms that may be given to the transverse section of
said bolts.
Fig. 9 is a side elevation of a rail with its iron supports.
Fig. 10 is the plan of portion of a complete way.
The head of the rail A is supported, on its outer side and throughout its whole
length, by a fish C which strengthens the rail, not only against vertical pressure
but also and specially against horizontal efforts. Moreover this continuous fish
plate secures an unvariable inclination of the rail against the middle of the way
and the pressure exerted upon any rail is distributed upon a longer part of the
way, wherefore the vertical bending of the rails in consequence of the weight of
ID 631

page_text: carriages and the horizontal bending of the same, as possibly caused in curves
of the way by the centrifugal force are likewise prevented.
The continuous fish C, Fig. 1, has a segmental transverse section and the cheeks
or ends of the same bear normally upon the inclined faces of the head and the foot
of the rail; it is fixed on this latter by means of the connecting bars E, the short
bolts F and F and the wedge-shaped gibs and cottars a and a¹.
The connecting bars E and the short bolts F and F¹ have like shaped transverse
section as shewn in Figs. 1, 7, 8, and 8ª. The outline of this transverse section is
composed of arcs of circles in order to allow of the holes in which these bars and
bolts are to be inserted, being made by simply boring and widening the same. In
consequence of the described form of transverse section, said bars and bolts have
each two longitudinal ribs bb, clipped in those parts which shall be lodged in the
holes of the rail A, the outer fish C and the inner fishes near the rail joints. Thus
prepared the bars or bolts are passed through the holes of corresponding shape in
the rail and in the fish or fishes, whereat the ribs b. b. project horizontally, and
after, these bars or bolts are turned about 90°, so that the diameter between said
ribs then has a vertical position, as shown in Fig. 1.
Obviously, the outline of the transverse section of these bars and bolts may be
varied in several manners, provided that this section always be composed of a
circle-shaped middle part having two projections on the opposite ends of one
diameter, the form of said projections may be any chosen one.
The sole point
in this construction is, that the ribless part of said bars or bolts, when inserted in
the perforations of the rail or fish, shall be allowed to be turned about 90°. The
ribs also may be clipped off from one end of said bars or bolts and this cylindrical
end then provided with screw threads and a locking nut, that holds together the
whole system. In the construction shown in the annexed Drawings the firmly
fastening together of the several parts of the way is produced by the wedges a a¹,
Fig. 3, which have a fork-like shape and act as gib and cottar. When these two
wedges are driven in their thin ends are bent up to prevent any loosening. The
remaining parts of the ribs, at the ends of the bars or bolts do the service of a rest
for these wedges and supply the place of screw nuts.
One of the characteristics of this system of entirely metallic superstructure
consists in the construction of the supports B, which, as shown in Figs. 1, 4, 5
and 6, have the shape of short pentagonal gutters turned upside down. The rails
rest immediately upon said supports, the upper face of which has for this purpose
an inclined position corresponding to the inclination the rails shall have towards
the middle of the way. Besides, the upper face of each support has a notch made
therein, this notch serving as a rest to the inner edge of the foot of the rail. Said
supports are preferably made from 35 to 40cm long and from 18 to 20m broad and
their notch has a parallel position with or a normal position to the edges of the
same, according as each support is intended to be placed longitudinally or trans-
versely under the rail. In those parts of the way that have little or no fall, it may
be preferable to place only one support across under each rail, viz, the middle one
(see Figs. 9 and 10); however in lines of more or less steep gradient, the number
of supports placed crosswise is increased preferably by arranging them alternately
with the longitudinal ones. This arrangement affords great horizontal and longi-
tudinal stability of the track. The hollow of the supports is entirely filled with
ballast gravel or broken stones in such a manner that the weight of the rails and
carriages is not borne by the edge of the said supports but by the entire internal
surface of the support resting on the ground formation.
For fixing the rails upon the supports, there are provided, besides the aforesaid
notches short bolts G, Figs. 1, 2 and 3, of an analagous form to that of the bolts F
and having, like these latter, two longitudinal ribs b¹ 6¹ of any chosen transverse
section and clipped off in the middle part of the bolt. These bolts are inserted into
corresponding perforations of the supports, said perforations having their jags or
slots for the passage of the ribs b' 61 placed longitudinally with respect to the rail.
Above each of these perforations of the supports rests a joining plate L likewise

page_text: perforated for the passage of bolt G and overlapping the foot of the rail that it
forces on to the support. After having passed the bolts G through plate L and
the support, they are turned about 90 degrees and then fastened by the fork-shaped
wedges a a¹ whose thin edges finally are bent up. At the joints of each two rails,
the overlapping ends of said joining plate L may be made somewhat longer and
enter a notch in the fish C.
The supports B are preferably made of Bessemer or other steel by pressing sheets
of the same at red heat into suitable dies.
The various parts of which this my system of permanent way consists, may be
made of iron steel or any suitable metal and of the dimension and strength herein
described with such modifications as may be required by the circumstances attending
its application.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
1ly In an iron or steel superstructure for railroads, supports B for the rails,
having the form of five-sided gutters turned upside down and being provided on
their upper side with a notch that forms a rest for the inner edge of the foot of
the rail; the hollow space of said supports being filled with ballast gravel or broken
stones in order to transmit the weight of the rails and carriages to the road-bed;
substantially as shown and described.
2ndly In an iron or steel superstructure for railroads, the strengthening of the
rails by continuous fishes C, fixed on the stem of the rails and running along
the outer side of each rail throughout the way and having a segmental transverse
section so that its upper and lower borders bear normally upon the inclined faces
of the head and foot of the rail, substantially as shown and described.
3rdly In an iron or steel superstructure for railroads, bolts and bars E, F, F¹
and G for fastening the fishes on the rails and the rails on the supports, these bars
and bolts having a cylindrical body or core and two longitudinal ribs, on the
opposite ends of the same diameter and said ribs being clipped off in those parts of
the bars or bolts which are to be lodged in the perforations of the stem of the rail,
the fishes or the support, in order to permit these bars or bolts being turned about
90 degrees, when inserted, substantially as shown and described.
4thly The fork-shaped wedges a a¹ for fastening the bars and bolts E F F¹
and G after having been inserted, substantially as shown and described. -
5thly An iron superstructure for railway, this superstructure consisting of a foot-
rail strengthened by a continuous external fish and resting upon supports that have
the form of short gutters turned upside down, are filled with ballast, gravel or
broken stones and placed discretionally end wise and crosswise as required under
the rail, substantially as set forth.
