PROVISIONAL SPECIFICATION
Improvements in Railway Rail Joints Using an Auxiliary Rail.
I, FRIEDRICH PAUL ALWIN VIETOR, Doctor of Philosophy, of 13, Taunusstrasse,
Wiesbaden, German Empue, do hereby declare the nature of this invention to be
as follows:-
.
• The invention relates to railway rail joints which are provided with an auxiliary
rail aanged aside of the joined ends of the main rails on the outside of the track
and fastened cn the sleepers as shown and described in Letters Patent
No 9639 A D 1892 Such auxiliary rails have a top surface, which slopes towards
both ends, and the invention consists in a method of producing both sloping
surfaces at a lower price and with a higher degree of durability Up to-day the
auxiliary rails are rolled as the ordinary railway rails and cut in pieces of proper
length Then the upper surface of the nail head is made sloping at both ends by
planing, milling or the like This work is very expensive and the inchined surfaces
shaped in such a manner are more liable to wear than the intermediate horizontal
part of the top surface of the ail head, this middle part being still coated with
the rolling-skin which has as is well known-a superior strength According
to the present invention the sloping surfaces in question are produced by
pressing down the ends of the head of the auxiliary rail either still hot from
iolling or reheated, so that the web is compressed and the head of the rail lowered
at both ends, whilst the foot of the ail keeps its straight shape throughout its
length When applying suitable dies the lowering of the rail head ends may be
facilitated by bending out the web ends
This method is very cheap and preserves the rolling-skin even at the ends of the
rail head.
Improvements in Railway Rail Joints Using an Auxiliary Rail.
I, FRIEDRICH PAUL ALWIN VIETOR, Doctor of Philosophy, of 13, Taunusstrasse,
Wiesbaden, German Empire, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and ascei-
tained in and by the following statement
-
The invention relates to railway rail joints which are provided with an auxiliary
1ail arıanged aside of the joined ends of the main tails on the outside of the track

page_text: and fastened
on the sleepers as shown and described in Letters Patent
No. 9639 A D 1892 Such auxiliary rails have a top surface, which slopes towards
both ends, and the invention consists in a method of producing both sloping
surfaces at a lower price and with a higher degree of durability Up to-day the
auxiliary rails are rolled as the ordinary railway rails and cut in pieces of proper
length. Then the upper surface of the rail head 18 made sloping at both ends by
planing, milling or the like This work is very expensive and the inclined surfaces
shaped in such a manner are more liable to wear than the intermediate horizontal
part of the top surface of the rail head, this middle part being still coated with
the rolling-skin which has as 18 well known-a superior strength According
to the present invention the sloping surfaces in question are produced by
pressing down the ends of the head of the auxiliary rail either still hot from
rolling or reheated so that the web 18 compressed and the head of the rail lowered
at both ends, whilst the foot of the rail keeps its straight shape throughout its
length When applying suitable dies the lowering of the rail head ends may be
facilitated by bending out the web ends
This method is very cheap and preserves the rolling-skin even at the ends of the
rail head.
Fig 1 represents an elevation of a 1ail joint with an auxiliary rail, the head
of the latter being bent down at both ends to produce inclined top surfaces
Fig 2 is a cross section taken along line 2-2 at Fig. 1
Fig 2 is a similar closs section showing double-headed rails supported in
chairs.
Figs 3 and 4 are cross sections on lines 3–3 and 4-4 of Fig 1 respectively
The middle part of the auxilary nail a is of equal height to the track-iails b,
whilst at the ends the 1ail-head 18 sloping, the web being bent out at aº in pro-
portion to the depression of the rail head. A double fish-plate c may be placed
between both rails to stiffen the joint
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same 19 to be performed, I declare that what I
claim is.-
In an auxiliary rail for railway-rail joints the head pressed down at both ends
and the web bent out in proportion to the depression of the head, essentially as
shown and described
