moved and form a water tight fastening.
These screw spikes constitute the primary
fastening whereby the rail is held to the
tie.
5 For the purpose of holding the rail se-
curely between the abutments 3 and 4 but
permitting the rail to be laterally adjusted
or vertically adjusted, or both, as the case
may be, rail braces 9 and 10 are provided.
10 The rail brace 9 has a horizontally extend-
ing web 11 with a head 12 which engages
against the web of the rail B and immedi-
ately beneath the head thereof. The outer
end of the web 11 is formed with a foot 12'.
15 This foot extends above the web 11 as at
13, and below the web 11 as at 14, the por-
tion 13 being relatively thick while the por-
tion 14 is thinner than the portion 13. The
outer face of the foot 12' extends down-
20 wardly in a vertical plane for a distance
corresponding to the vertical face 6 of the
abutment 3 and then extends downwardly
and outwardly corresponding to the down-
wardly and outwardly extending face 5 of
25 the abutment 3. Inasmuch as the abutment
is inclined to the longitudinal axis of the
rail, the outer face of the foot 12' is also
inclined longitudinally to correspond to the
inclination of the abutment. The outer face
30 of the foot 12' is formed with teeth inter-
meshing with the teeth 6 of the adjacent
abutment. It will be seen, therefore, that
the brace 9 may be shifted longitudinally
with respect to the abutment 3 and that as
35 it is shifted longitudinally in one direction
it will be shifted laterally nearer to the
middle of the base plate 2 and that when
shifted in the opposite direction the head
will be disposed farther from the middle of
40 the base plate. It is to be particularly noted
that the rail brace 9 engages just beneath
the head of the rail and does not engage the
base flange of the rail.
The rail brace 10 is adapted to move both
45 longitudinally along the rail and also ver-
tically to permit an elevation of the rail.
The rail brace 10 is formed of a web having
an outer body portion 15 and two inwardly
directed spaced arms 16, the ends of the
50 arms being divergently turned as at 17 to
provide heads engaging one beneath the
head of the rail, and the other engaging at
the junction of the web with the base of the
rail. The outer face of the body portion 15
55 of the rail brace 10 is inclined at the same
angle as the inner face of the abutment 4
so as to coact therewith, and this inner face
is formed with a plurality of notches 18 en-
gageable by the point of a set screw 19.
co This screw passes through the abutment 4
and is, of course, provided with a head 20
whereby it may be set.
It will be obvious now that in order to
shift the rail laterally in one direction, as
65 for instance toward the left in Fig. 3, therail brace 9 will be shifted longitudinally
along the abutment 3 toward the converg-
ing end of the abutment, while the rail
brace 10 will be shifted longitudinally along
the abutment 4 in the opposite direction 70
and that when it is desired to shift the rail
to the right in Fig. 3, the rail braces 9
and 10 will be respectively shifted in the
opposite directions to that above described.
The rail brace 9 is, of course, held in shift- 75
ed position by its engagement with the teeth
6 while the rail brace 10 is held in its shift-
ed position by engagement with the set
screw 19.
If it is desired to elevate the rail, as by so
means of shims inserted beneath the base of
the rail, the set screw 19 is loosened and a
shim inserted beneath the base of the rail
which will elevate the rail the distance de-
sired. The brace 9 will not be elevated with 85
the rail but the brace 10 is lifted with the
rail and is held in its adjusted position by
the set screw 19 engaging with a corre-
sponding notch in the brace 10. It will be
noted that no longitudinal movement of the 90
brace 9 can occur because of its engagement
with the teeth 6 and that no vertical move-
ment of the brace 9 can occur because the
portion 14 of the brace has a face which
coacts with the undercut face 5 of the abut- 95
ment 3. The head 12, however, of the brace
9 is of such depth or thickness as to permit
the elevation of the rail.
It is to be particularly pointed out that
this form of rail chair supports the rail se- 100
curely and braces the rail against any lateral
thrust. The outside flange of the rail is en-
tirely free so that there is no liabilityof frac-
ture of this outside flange and the inside brace
10 while securing the flange from any tipping 106
thrust, is so designed as to allow a semi-resili-
ency in. the brace which will eliminate frac-
ture. This semi-resiliency is secured by pro-
viding the arms or spaced portions 16, which
have a certain relative resilient yielding move- 116
ment. It will likewise be observed that the
movable primary parts of this chair and
particularly the set screw, are within plain
sight so that any mal-adjustment of the
chair or these movable parts thereof, may 115
be readily observed by a track walker, in-
spector, or a member of a train or engine
crew. This is a considerable factor in the
elimination of hazards as it permits the op-
erator at one glance to determine whether 120
the movable parts and the set screw are in
proper position or not.
The improved rail chair permits of ready
adjustment of the rail either vertically or
laterally, it holds the rail securely and posi- 125
lively in adjusted position and it is inexpen-
sive to manufacture. The base plate may be
made either of rolled, cast or pressed shapes.
The chair is particularly designed for use
on easy curves, on old - established lines 1300
