TRACK RAIL JOINT
Edmund M. Livingston, Edgewood, Pa.
Application June 18, 1936, Serial No. 85,829
8 Claims.
(01. 238-244.)
This invention relates to track rail joints, that
is to say, to means for securing together the con
tiguous ends of aligned sections of railroad track
rails.
In the main, my invention is directed toward
5
the provision-of a rail joint structure wherein the
parts are so organized as to not only reinforce
the rails against lateral ?exure along the length
of the joint, but which will, as well, effectively
10 brace the center webs of the adjoining rail sec
tions, and at the same time vertically stiffen said
rail sections against vertical ?exure under load,all to the end of rendering the joint substantially
rigid and minimizing wear of its component
-‘ parts.
In connection with a rail joint structure having
the above attributes, it is a further aim of my
invention to make possible, through wedge‘ action
between the component‘ parts, the taking up of
Fig. II, these splice bars are of substantially chan
nel cross sectional con?guration and character
ized by outwardly-bowed ?exible vertical webs I3
that connect top and bottom ?anges I4, I5. At
their bottoms, the splice bars I2 are reinforced
by outward continuations I5a of. the ?anges I5;
and it will be noted that said bars are so proporé"
tioned as to ?t, ?anges ?rst, into the side hol
lows of the aligned rail sections III at opposite
sides of the vertical center webs I6. The top
faces of the ?anges I4, it will be further observed
from Fig. II, are sloped as at IT to correspond
with the slopes I8 of the bottom faces of‘ the rail
head I9. Similarly, the bottom faces of the lower
?anges I5 of the splice bars I3 are sloped as at
20 to correspond with the declination 2I of the
base ?anges 22 of. the rails I0.
‘
'My improved joint further comprises wedge‘
bars 23 which correspond in length to the splice
bars I2 and which in turn ?t the hollows of said
splice bars. The upper and lower edges‘of the
periods of. service.
Another object of my invention is to provide‘ wedge bars 23 are sloped outwardly contrariwise
‘ wear as it occurs in the joint after extensive
rail connecting means wherein the parts are
adaptable to the formation of effective joints in
instances where the heads of old rails are worn
adjacent the ends of adjoining sections or where
therail base?anges are worn at the end regions
of the joints.
_
Still other objects and attendant advantages
30 of this invention will be manifest from the de
tailed description following in connection with
the attached drawings, wherein Fig. I is a frag
mentary‘ view inside elevation showing a four
bolt track rail joint embodying my invention.
Fig. II is a cross sectional view of the joint,
taken as indicated by the arrows 11-11 in Fig. I,
and drawnv to a larger scale.
Figs. III and IV are perspective views respec
tively of. one of the splice bars and one of the
40 wedge bars comprised in my improved joint.
Fig. V is a side view of the wedge bar shown in
Fig. IV.
Figs. VI and ‘VII are views corresponding to
Fig. V showing slightly modi?ed forms of wedge
' bars adapted to be used at worn joints; and,
Fig. VIII is a side view of a six hole splice bar
constructed in accordance with my invention.
With detailed reference ?rst more particularly
to Figs. I and II of these illustrations, the nu
at an acute angle as at 24, 25 to correspond with
and engage complementary slopes 26, 21 respeci
tively at the bottoms of the top‘ ?anges I4 of the
splice bars and the tops of the lower ?anges‘ I5
of said splice bars. The backs of the wedge bars
are curved as at 28 and adapted to abut the center
web I6 of the rail at opposite sides, the curvature
of the wedge bars being somewhat less than. that 30
of the rail sides so as to permit rocking and
positional-self adjustment of said wedge bars in
respect to the splice bars. As shown in Figs. I
and III, the splice bars I2 are in this instance
provided with four holes 29 through their bowed 35
webs I3 substantially midway of the height of
the latter, while the wedge bars 23 are similarly
provided with holes '33 at corresponding intervals
as shown in Fig. IV for passage of draw bolts such
As shown 40
as indicated at 3| in Figs. I and II.
in Fig. III, the holes 29 in the splice bars I2 are
made elliptic to receive the correspondingly
shaped portions 3Ia of the bolts 3|. The holes
30 in the wedge bars 23, on the other hand. are
made circular to conform. with the cross section $5
of the'shanks of the bolts 3|. For a purpose
hereinafter explained, the splice bars I2 are
longitudinally slit as at 32 between the inner two
of the bolt holes 29.

rail sections which meet at the joint, the split
of the joint being indicated at II. The joint
organization of my invention, it will be observed,
comprises a pair of splice bars I2, I2, which are
' exact duplicates of each other. As shown in
and the wedge bars 23 are assembled at oppo
site sides of the joint as shown in Fig. II, and
50
the bolts 3| passed through the apertures 29,
30 in the parts I2 and 23, and also through pre
allocated registering apertures 33 in thevertical 55
2,116,463
center webs l6 of the rail ends l0. As the nuts 34
associated with the bolts 3| are tightened, it will
be evident from Fig. II that, by the action of the
wedge bars 23, and pull of the bolts, the splice
bars will be drawn inward and their curved webs
l3 ?attened. This action is attended by ver
tical expansion of the splice bars |2 whereby the
sloping surfaces at H and 20 are brought into
?rm contact with the contiguous sloping surfaces
10 l8, 2| of the rail heads and base ?anges, and the
surfaces 26, 21 similarly brought into ?rm con
tact with the contiguous surfaces 24, 25 of the
wedge bars 23, the latter being free to rock on
the curved sides of the web l6 of the rail to ac
15 commodate the action. With the parts as
sembled and secured as illustrated in Fig. II, the
contiguous ends of the rail sections II] are ef
fectively braced both against up and down and
lateral ?exure, the overhangs of the rail heads
l9 being supported along the dotted lines :1:—:v in
Fig. II through interposition between said head
and the rail base ?anges 22, of the ?anges I4,
I 5 of ‘the splice bars |2 and the wedge bars 23. In
other’ words, the arrangement in effect provides
between the heads I9 of the rail sections H! and
the rail base ?anges substantially solid columns
of metal which greatly add to the rigidity of the
joint as a whole and strengthen it to better with
stand‘ the loads of passing trains. At the same
time, the wedge bars 23, by abutting the center
webs of the rails I0 brace the latter throughout
their height and thus stiffen the joint against
lateral ?exure.
@As'a consequence of being slitted at 32, the
splice bars l2 have the capacity to yield more
readily to being vertically expanded by the wedge
bars 23 incident to drawing up of the bolts 3| as
above explained. The slits 32 may however be
omitted if desired without impairing the action
of the splice bars. In the latter case, however,
greater effort will have to be expended in draw
ing up on the bolts 3|.
' As wear occurs in the joint, it may be taken up
from time to time simply by drawing up tighter
on the bolts 3| to bring the wedge surfaces of the
several parts into closer contact as required. In
order‘to prevent the formation along the wedge
surfaces of the parts of shoulders such as would
be likely to interfere with the e?iciency of the
_ joint, I preferably round the upper and lower
?anges ‘l4, |5 of the splice bars |2 as at 35, 38
and cut back the slopes 21 of the ?anges l5 ad
jacent the webs l3 as at 31, 38.
:For new rails, I employ in conjunction with
65 the splice bars |2, wedge bars 23 having absolute
ly straight and parallel top and bottom edges as
shown in Figs. 1, IV and V.
' In ‘the modi?ed wedge bar 2317- delineated in
ends 4| 0 as will be seen by comparison with the
dot—and-dash horizontal lines shown at 42, 43.
Bars of the type 230 are thus useful in instances
where the base ?anges of the rail or the splice
bars |2 have been worn at the end regions of the
joint. When incorporated in the joint, the wedge
bars 230 will warp, i. e., adapt the splice bars |2
to the channel con?guration of the rail sections
at the worn regions aforesaid.
Fig. VIII shows a siX hole splice bar |2d, which, 10
except for having two additional bolt holes and
being longer than the splice bar of Fig. III, is
identical with the latter, its slit 32d being con
tinuous through the four bolt holes 2912 at the
center of the bar. Obviously, the wedge bars to
be used in association with the splice bar |2d of
Fig. VIII are made to a corresponding length and
similarly provided with six bolt holes.
To those skilled in the art, it will be apparent
from the foregoing that I have provided a novel 20
joint organization whereby the ends of the con
tiguous rail ‘sections are connected more rigidly
and solidlythan is possible with joints of ordi—
nary construction. Accordingly through my in
vention, the rails are more e?ectively strength 25
ened and brace both against vertical and lateral
?exure with attendant minimization of wear of
the parts and assurance of correspondingly
greater longevity of the joint.
Having thus described my invention, I claim: 30
1. A track! rail joint comprising a pair of
vertically-expansible channel section splice bars
adapted to engage, ?anges ?rst, into the hollows
of the alignedrail sections, the top and bottom
?anges of said bars being tapered for wedging
action respectively with the rail heads and base
?anges of said sections and connected by out
wardly-bowed-?exible webs; wedge bars with con
vexed backs abutting opposite sides of the vertical
webs of the rail ends and in turn adapted to 40
engage the hollows of the splice bars, said wedge
bars having their top and bottom longitudinal
surfaces counter-sloped outwardly for wedging
action with the in-sides of the splice bar ?anges;
and transverse vbolts operative to draw inward
upon the bowed webs of the splice bars.
2. A track rail joint comprising a pair of out
wardly-bowed vertically-expansible channel sec
tion splice bars adapted to engage, ?anges ?rst,
into the hollows of the aligned rail sections at
opposite sides of the joint; wedge bars with con

Wedge bars, said wedging ?t normally opposing
the center 39 at a slight angle indicated in each
instance at 40 toward the opposite ends 4| of the
bar. This modi?ed bar 23b‘ is designed for use
with rail sections wherein the bottom faces of
the heads have been worn adjacent the split of
the juncture. The effect of the bars 23b in an
assembled joint will, under the drawing action of
the bolts 3|, be to raise the center portions of
the top ?anges I4 of the splice bars |2 into con
inward movement of the splice bars.
