the rail base on the end thereof opposite from the leg
28 underlying the rail. The tie plate engaging the leg
36 extends into one of the vacant spike holes 21 in the
tie plate so that when the anchor member is clamped
to the rail the tie plate is positively engaged and thereby
coupled to the rail. The leg 36 is desirably long enough
to extend through the tie plate and dig into the surface
of the rail 17 so as to insure a complete engagement with
the tie plate.
Turning now to the wedge member 26, it will be noted
that it comprises a shank 38 which is relatively long
compared to the width of the channel 32 in the anchor
member 10 and is formed with an inclined ramp 39 at
one end and a large ?at head 40 at its opposite end. The
upper surface 41 of the shank is tapered upwardly from

on maintaining good contact with an edge of the tie.
Accordingly, the condition of the tie is not a factor in ob
taining a secure anchor against rail creepage.
While the anchor is extremely effective in the direction
in which the wedge is driven, it will be appreciated that
because the rail and the tie plate are clamped together and
the tie plate is spiked to the tie, the anchor will also be
effective in the opposite direction, particularly so when
the rib on the anchor member and the cooperating gashes
in the wedge member are employed.
The anchor member is formed, for example, as a steel
forging and thus has some degree of resiliency. This
allows the wedge member to be driven tightly between
the anchor member and the rail without danger of break
ing the anchor, and adds considerable strength and tough

immediately adjacent the head 40, the underside of the
wedge member thence tapering perceptibly downwardly
to de?ne an acute angle with the outer face of the head
40. This angle in turn de?nes a sharp biting edge 44
along the bottom of the head which is sharp enough to
bite into the upper surface of the rail base as the Wedge
member is driven up tight under the middle U-shaped
portion 30 of the anchor member 25.
To further preclude retrograde movement of the wedge
member after the same has been driven up tight between
the rail base and the anchor member, a detent means
can be interposed between the wedge 26 and the anchor
member 25. In the present instance one such means

face of the rail base. By the same token, the sharp
angular edge at the head of the wedge member is pressed
harder ‘against the rail base and bites into the surface
thereof. Also because of the space between the lower
surface of the rail base and the horizontal portion 36
of the rail anchor 25, a bending moment is applied to
the rail base upon the wedge member 26 being driven
into place and the rail base edge biting into the
vertical reverse bend portion 31. Under these condi
tions, longitudinal creepage of the rail in the same direc
tion as the wedge member has been driven will be effec
tively opposed as a result of the biting engagement be
tween the sharp edge of the wedge and the upper surface
of the rail and the positive engagement of the anchor
member with the tie plate on which the rail is mounted,
the rail is restrained against longitudinal creepage.
