My improved track construction embodies rails
constructed in a particular manner, tie plates ap
plicable thereto and constructed in c
onformity

therewith, and splice bars or angle bars also con
structed in conformity with the particular con
struction of the rails, all of these parts cooperat
ing to produce an economic track construction of
high merit and utility. The various parts ‘of my
improved track construction will now be de
scribed in detail.
In the drawings, I have shown the ends of two
adjoining rails Ill and Mia and the associated
structure used in conjunction therewith. Rails
l9 and Ma being identical in construction, only
rail ED will be described in detail. The rail I 0
is constructed with a head 52 on which the wheels
of the rolling stock carried by the track travel
15 and a web l3 connected thereto. The web 13
issues upwardly from a base M which is of a
suitable width to give the desired strength to the
rail. The base I4 is formed upon the underside
l5 thereof with a hollow I6 which extends longi
20 tudinally throughout the length of the rail and
which in the particular embodiment of the in
vention disclosed, is preferably in the form of a
concavity extending from one lateral edge I‘!
of the base M to the other lateral edge l8 thereof.
In the drawings, the concavity or hollow I6 is of
the full width of the rail, though, if desired, the
same may be of lesser lateral extent, providing
' the same is arranged medially of the lateral edges
of the rail base. The base I4 of the rail is pref
30 erably ?rst rolled in the customary manner and
thereafter bent out of the plane of the bottom
thereof to form the concavity Hi. In thus rolling
the section, pressure is applied to the upper sur
face of the rail outwardly ofra locality indicated
35 by the reference numeral [9 in Fig. 7 leaving a
surface 20 on either side of the web [3 of pre
determined angularity for a purpose to be pres
ently more fully referred to. The adjoining sur
faces 2] have different degrees of angularity or
convexity, sloping more abruptly than the sur
faces 29. By constructing the rails in this man
ner the height of the rail is increased without
increasing the weight. This increases the mo‘
ment of inertia of the rail and consequently its
45 strength. The arch action of the base of the rail
also enhances its strength.
For the purpose of splicing the adjoining rails
IO and lila, splice bars or angle bars such as
indicated at 22 and 23 in Fig. 5 are used. These
50 bars are constructed with upper and lower ribs
66 and 61 which are formed with beveled sur
faces 24 and 25 engaging the heads l2 of the
rails upon the under surfaces 26 thereof and the
rail base l4 upon the surfaces 20 thereof. Bolts
55 27 passing through said splice bars and the web
l3 of the rail hold the parts in proper position.
Due to the construction of the base M of the rail
ID, the rib 6'! which extends outwardly from the
major portion of the splice bar may be bent
downwardly so that the portion 68 of surface 25
which lies outwardly of the line IQ of the sur
face 2d of. the rail base has a greater degree of
inclination than the other portion thereof.
This increases the moment of inertia of the
65
angle bar without increasing its weight, thereby
increasing the strength of the same. It will read
ily become apparent that the above noted in
crease in strength of the angle bar, and the
consequential increase in the strength of the
70 entire-track construction is made possible by the
particular construction of the rail base l4.
In the use of my invention, tie plates are pref
erably used on each tie and particularly under
the joints. In the drawings, a tie plate II is
V75
shown which supports both of the rails I0 and
Illa.
The particular manner in which the rails
cooperate With the tie plate being identical, the
following description will refer to rail It! only.
The tie plate ll comprises a plate-like body por
tion 28 which is of a suitable length and of a
width considerably greater than the width ofv the
rail base M. This body portion has issuing up
wardly from it two spaced abutments 29 and 30
which are disposed a distance apart greater than
the width of the rail base l4, and which are dis
posed inwardly from the lateral edges of the tie
plate to provide an intervening portion 3! which
is constructed with a bearing surface 32 on
which the rail rests and with marginal portions
33 and 34 by means of which the tie plate may 15
be secured to the tie. The under surface 35
of the tie plate is preferably planiform and rests
directly upon the tie.
The edge 18 of the rail base i4 is adapted to
extend up to a substantially vertical shoulder 36 20
formed on abutment 36 which limits the move
ment of. the said rail laterally in one direction.
This abutment is formed with an overhanging
flange 3? which overlies the base M of the rail I0
and which limits movement of this portion of 25
the base away from the tie plate. In actual use
the distance between the ?ange 3'! and the body
portion 3! of the tie plate is somewhat greater
than the thickness of the rail base !4 at the
edge 48 thereof. This leaves a space 38 there—
between which permits of a slight movement of
the rail base away from the tie plate.
The abutment '29 as previously brought out is
spaced from the edge ll of the rail base Hi. The
face 39 of this abutment forms another shoulder 35
similar to the shoulder 36 of the abutment 30.
This shoulder is beveled, being closest to the rail
base at its upper end so as to form a longitudinally
extending dovetailed groove 4%) in conjunction
with the edge I’! of said rail base. Cooperating 40
with this groove is a key 4| which functions in
a manner similar to abutment 30 and ?ange 3'! to
engage the rail base on the opposite side thereof
and to hold the same securely attached to the
tie plate. ' This key may be constructed of a rel
atively softer material than the tie plate or rail
to take up the wear occasioned through lateral
strains.
The key 4! includes a longitudinally extending
tongue 42 which is dovetailed and of such dimen 50
sions as to ?t within the dovetailed groove 40.
This key is preferably of a length less than the
distance between ties or tie plates so that the said
key may be readily inserted into the groove 46
and slid longitudinally thereof until the same 55
occupies the position shown in Figs. 1 and 2. The
key 4! is constructed with an overhanging ?ange
43 which overlies the upper surface 2! of the rail
base 14 adjacent the edge I‘! thereof and which
serves a purpose similar to that of the ?ange 31 60
on abutment 30. This ?ange in normal position
is also slightly spaced from the upper surface 2|
of the rail base I4 to permit of slight movement of
the said base away from the tie plate thereby
preventing excess pumping of the tie. The edge 65
80 of said ?ange 43 is beveled as shown in Fig. 6
to facilitate removal of the splice bar from the
rail joint.
The key 4! is held in position with respect to
the tie plate by means of a screw 44. This screw 70
is formed with a wrench head 45 by means of
which the same may be rotated and also has a
threaded shank 46 adapted to screw into threads
4'! formed in the upper portion of the key 4|.

to move the key 4| for an appreciable distance
longitudinally to procure wedge action as de
30 toward the edge ll of the rail base M.
scribed, the dep-ression 49 is constructed elongated
as best shown in Figs. 1 and 4, whereby suf?cient
movement may be had to procure the desired
frictional results.
In addition to the particular construction of
the face 39 of the abutment 29 in the manner
shown for the purpose of procuring wedge action,
the upper surface 52 of abutment 29 and the por
tion 69 of surface 32 adjacent abutment 29 are
arranged on a slight incline. Cooperating with
the surface 52 is a ?ange 53 formed on key 4!.
The tongue 42 likewise cooperates with surface
69.
The flange 53 and tongue 42 are also ar
ranged in an inclined manner so that as the key
travels along the groove 40 the said key is raised
upwardly. Upward movement ‘of the key causes
the tongue 42 to ride along the beveled face 39 of
abutment 29 which in turn crowds the key in
wardly. urging the shoulder 5| thereof into en
gagement with the edge H of the rail base l4. It
will thus be seen that longitudinal movement of
the key in one direction causes the said key to
travel inwardly due. ?rst to the disposition of the
face 5| of abutment 29 and also due to the sliding
movement of the tongue 42 of the key along the
face 39 of said abutment by reason of the inclina
tion of the surfaces 52 and 59 of the tie plate.
In order to maintain contact between the key
60
4| and the edge i‘! of the rail Hi. I have provided
a compression coil spring 54 which encircles the
lug 48 ‘formed on the end of the screw 44 and
which engages the shoulder 55 formed on said
screw at the end of the threads thereof. This
spring further seats upon the portion 59 of the
upper surface 32 of the body portion 28 of the tie
' plate and urges the key 4| upwardly, causing the
tongue 42 thereof to slide along the beveled face
39 of abutment 29. This spring thus maintains
the shoulder 5| at all times in engagement wlth
the edge H of the rail base M.
In the construction of my improved tie plate
the rail sup-porting surface 32 of the body 28
is preferably arranged on a slight incline so that
transverse to the rail so that the said surface
recedes from the surface 56 at the corners of the
bearing surface 32 of the tie plate.
It will thus
be seen that at such corners, relief is provided so
that the base iii of the rail is free from the same. 30
The concave construction of the rail and the
complement-a1 surface of the tie plate serve to
restrain lateral movement of the rails with re
spect to the tie plate, thereby decreasing the wear
on the keys. At the same time, breakage of the 35
rail flange when the rail is subjected to lateral
forces is greatly reduced. Due to the formation
of the rail the movement of inertia of‘ the rail is
increased, producing a corresponding increase in
without increase in weight.
For the purpose of attaching the tie plate to a
tie the marginal portions 33 and 34 of the body
portion 28 of the tie plate are constructed with.
rectangular holes 5| extending therethrough.
through which suitable rail spikes 52 may be _
driven into the tie proper.
The manner of using my invention is as fol
lows: After the ties have been laid the tie plates
are applied to the ties and positioned thereon by
means of a suitable rail gauge. The tie plates
are then attached to the ties by means of the rail
spikes 62 which are driven'through the holes 6|
formed in the marginal portions 33 and 34 of the
body portion 28 of the tie plates and into the ties.
After the tie plates are in position, the rails are
placed thereon and the bases thereof moved under
the flanges 3i of the tie plates and until the
edges l8 of said rails engage the shoulders 36 of
the tie plates. Keys iii are now applied by in
sorting the tongues 42 thereof into the grooves
40 and the said keys driven in. until the shoulders
5| thereof engage the opposite edges ll of the
rail bases. Springs 54 are next inserted through
the threaded openings in the keys 4| and the
screws
applied. When these screws enter the
depressions 5'53 the keys are heid in position and
the rails become attached to the tie plates.
My invention in addition to holding the rails
in position, prevents creepage of the rails rela
tive to the ties. Toward this end the tie plates 70
are preferably alternately arranged in reversed
manner on the various \ties so that the keys are
inserted from opposite ends of the tie plates on
alternate ties. Due to the tapering of the bev
eled face of the abutments of the tie plates, the 75
4
2,133,317
keys are caused to travel along the dovetailed
grooves when there is any creepage of the rails.
This causes wedge action, clamping the edges
of the rail base securely between the shoulders
of the tie plates which has the effect of restrain
ing longitudinal movement of the rails. By re
versing alternate tie plates, resistance to move
ment of the rails in either direction can be pro
cured. It will thus be seen that the invention
not only serves to hold the rails attached to the
ties, but also serves to prevent creepage of the
rails longitudinally with respect to the ties.
In Fig. 8 I have shown a slight modi?cation
of the invention in which the supporting or bear
15 ing surface of the tie plate is constructed some
what di?erently than that shown in Fig. 3. The
supporting surface there illustrated is designated
by the reference numeral 53 and is cylindrical
in form having its axis situated longitudinally.
The curvature of this surface is preferably the
II4 permitting a slight relative movement be
tween rail base and tie plate and preventing
’ excess pumping of the ties.
The abutment I29 as previously brought out
is spaced from the edge II‘! of the rail base H4.
The face I39 of this abutment forms another
shoulder similar to the shoulder I36 of abutment
I30. This shoulder is beveled, being closest to
the rail base at its upper end so as to form a
longitudinally extending dovetailed groove I40
base. Cooperating with this groove is a key I4I
which functions in a manner similar to abut
ment I 30 and ?ange I 31 to engage the rail base
on the opposite side thereof and to hold the same 15
securely attached to the tie plate. This key may
be constructed of a relatively softer material than
the tie plate or rail to take up the Wear occasioned
through lateral strains.
The key I4I includes a longitudinally extend 20
ing tongue I42 which is dovetailed and of such
same as the curvature of the concavity or hollow
It of the rail base I4. The corners ‘64 of the
surface 53 are cut down so as to afford relief
dimensions as to ?t within the dovetailed groove
from pressure against the rail base at such local
the distance between ties or tie plates so that
ities.
This serves the same purpose as the por
tion 51 of surface 32 in the other form of the
invention.
In Figs. 9, 10, l1 and 12 I have shown another
form of my invention. In these views the rails
are designated by the numerals I III and I Illa and
the tie plate which cooperates with the rails by
the numeral II I. These parts will now be de
scribed in detail.
The rail III} is constructed with a head II2
35 on which the wheels of the rolling stock carried
by the track travel and a Web II3 connected
thereto. The web II3 issues upwardly from a
base I I4 which is of a suitable width to give the
desired support to the rail. The undersurface
40 IIE of the base H4 has a concavity II6 through
out the central area thereof and is ?at in prox
imity to the lateral edges II‘! and II 8 thereof.
The upper surfaces I23 and I2I of the base II4
are constructed similar to the rail III.
45
The tie plate I II comprises a plate-like body
portion I28 which is of a suitable length and of
a Width considerably greater than the width of
the rail base II4. This body portion has issuing
upwardly from it two spaced abutments I29 and
50 I39 which are disposed a distance apart greater
than the width of the rail base H4, and which
are disposed inwardly from the lateral edges of
the tie plate to provide an intervening portion
I3I which is constructed with a bearing surface
55 I32 on which the rail rests and with marginal
portions I33 and I34 by means of which the tie
plate may be secured to the tie. The under sur
face I35 of the tie plate may be constructed
either as shown in Fig. 3 or Fig. 8, the form
60 illustrated being similar to that shown in Fig. 8,
except that the curved protuberance I69 thereof
is narrower to ?t the concavity II5.
The edge II8 of the rail base I I4 is adapted
to extend up to a substantially vertical shoulder
65 I36 formed on abutment I39 which limits the
movement of the said rail laterally in one direc
tion.
This abutment is formed with an over
hanging ?ange I3l which overlies the base II4
of the rail III] and which restrains movement of
70 this portion of the base away from the tie plate.
In actual use the distance between the ?ange
I3‘! and the body portion I3I of the tie plate is
somewhat greater than the thickness of the rail
base H4 at the edge II 8 thereof. This provides
75 clearance between the ?ange I31 and said base
10
in conjunction with the edge II"! of said rail
I43. This key is preferably of a length less than
the said key may be readily inserted into the
groove I 49 and slid longitudinally thereof until
the same occupies the position shown in Figs. 9
and 10. The key MI is constructed with an over
hanging ?ange I43 which overlies the upper sur
face I2I of the rail base II4 adjacent the edge 30
II‘! thereof and which serves a purpose similar
to that of the ?ange I 31 on abutment I30. This
?ange in normal position is also slightly spaced
from the upper surface I2I of the rail base II4
to permit of slight movement of the said base 35
away from the tie plate. The tongue I42 of key
MI is constructed with a shoulder I5I which
corresponds to the shoulder I36 of abutment I30.
This shoulder engages the edge II‘! of rail base
H4, and is constructed arcuate as best shown in
Fig. 9 so as to engage the edge of the rail at one
locality intermediate the ends of the tie plate.
This feature of the invention compensates for
irregularities in construction of the tie plate and
rail and concentrates the pressure on the rail at 45
a predetermined locality.
The key MI is held in position with respect to
the tie plate by means of a screw I44. This screw
is formed with a wrench head I45 by means of
which the same may be rotated and also has a 50
threaded shank I46 adapted to screw into threads
I 41 formed in the upper portion of the key I42.
The intermediate portion 2I‘6 of the shank I455 of
screw #44 is turned down to eliminate the threads
and the extreme end I48 of said shank is further 55
reduced in diameter to form a shoulder Hi9 adja
cent the intermediate portion 2I6. The reduced
end 548 of screw I44 serves as a lug for limiting
movement of the key with respect to the tie plate.
This lug enters a transverse slot M9 in the body
portion I3I which is of a width substantially
equal to the diameter of the lug I48 and of a
length greater than the diameter of said lug so
as to permit transverse movement of the key Id!
with respect to the rail III]. The shoulder I I9 65
seats against the upper surface I32 of the body
portion I3I of the plate HI and as the screw is
rotated causes the key I4I to travel upwardly.
Upward movement of the key causes the tongue
542 of said key to travel upwardly along the bev 70
eled face I39 of abutment I29, which urges the
shoulder I5I into engagement With the edge In
of the rail base H4. The screw I44 may travel
laterally by reason of the slot I 49 to accommo
date movement of the key toward the rail. A 75
2,133,317
notch I20 in abutment I29'receives the intermedi
ate portion 2I8 of screw I44, when the key is in
its farthermost position with respect to the edge
II'I of rail base II4.
Encircling the shank I46 of screw I44 and
seated against the head I45 of said screw and the
?ange I43 of key MI, is a compression coil spring
I50. This spring serves to prevent accidental ro
tation of the screw I44 and holds the parts in
adjusted position.
For the purpose of attaching the tie plate to
a tie the marginal portions I33 and I34 of the
body portion I28 of the tie plate are constructed
with rectangular holes I6I extending there
through through which suitable rail spikes I62
may be driven into the tie proper.
The manner of using my invention is as fol
lows: After the ties have been laid the tie plates
are applied to the ties and positioned thereon by
means of a suitable rail gauge. The tie plates are
then attached to the ties by means of rail spikes
I62 which are driven through the holes IBI
formed in the marginal portions I33 and I34 of
the body portion I28 of the tie plate and into the
25 ties. After the tie plates are in position, the rails
are placed thereon and the bases thereof moved
under the ?anges I31 of the tie plates and until
the edges H8 of said rails engage the shoulders
E36 of the tie plate. Keys I4I are now applied by
,30 inserting the tongues I42 thereof into the grooves
thereof and said tongues slid along the grooves
until the threaded openings in said keys register
with the slots M9. Screws I44 with springs I53
encircling the shanks thereof are next screwed
35 into the threads I41 until the lugs I48 enter the
slots I49, and shoulders II9 seat against the sur
faces I32 of the tie plates.
As the screws are
further screwed into the keys the said keys raise
and slide along the beveled faces I3I of abut
40 ments I29. This crowds the shoulders I5I of the
keys against the edge In of the rail base and
clamps the rail securely in position.

parts are required than with other similar tie
plates now in common use for the purpose. With
my invention breakage of the rail base is greatly
55 reduced and the rail caused to properly seat
upon the tie plate. My improved tie plate is con
siderably lighter in weight than the tie plates now
used and in addition is fully as strong. There are
no fragile parts to break or get out of order with
my invention and where wear occurs, shims may
be readily applied to take up the Wear. With my
invention the greater part of the wear occurs on
the keys when the keys are constructed of a softer
material and when wear becomes excessive, new
keys may be susbstituted without requiring com
‘ plete new tie plates. Both the rail and splice bars
are strengthened by means of the construction
used with my invention.
Changes in the speci?c form of my invention,
70 as herein disclosed, may be made within the scope
of what is claimed without departing from the
spirit of my invention.
