away from the stringer 1, by manipulating
the set screws 50. These set screws 50,
further, limit positively the inward move-
ment of the angle member 3, when the same
5 is advanced by tightening up the nuts 7.
In connection with the stringer 100, which
is adjacent the sawing mechanism, the struc-
ture above described is duplicated in many
particulars, saving for the fact that the
10 angle member 3 is duplicated by a flat plate
300 having no flange corresponding to the
flange 5 of the angle member 3. The plate
or strip 300 supports a rail 15a, which is like
the rail 15, saving for the fact that the
15 lateral edges of the rail 15 are not beveled.
The rail 15a is secured to the plate or strip
300 by means of rivets 16a. In connection
with the stringer 100, the plate or strip 300
and the rail 15a, many parts hereinbefore de-
20 scribed are used, these parts being desig-
nated by numerals hereinbefore employed,
with the suffix "a".
The construction of the device herein dis-
closed is such that, after a saw mill car-
25 riage track has moved out of alinement after
the repeated thrusts exerted on the carriage
by the logs or timbers as the latter are
mounted on the carriage, the tracks
may be lined up readily. As a matter
30 of experiment, one man in an hour or
less can line up a stretch of track, the aline-
ment of which hitherto has required the ef-
fort of two men, for a day, in the absence
of such a structure as that disclosed in this
35 application.
Having thus described the invention, what
is claimed is:
1. In a saw mill carriage track, a
stringer; an angle member including a hori-
40 zontal flange located on top of the stringer,
and a vertical flange located at one side of
the stringer; a rail carried by the horizontal
flange; means coacting with the stringer
and the vertical flange for moving the angle
45 member transversely of the stringer; and
means coacting with the horizontal flange
and the stringer for holding the angle mem-
ber in adjusted positions transversely of the
stringer.2. In a saw mill carriage track, a stringer; 50
an angle member comprising a horizontal
flange located on top of the stringer, and a
vertical flange depending at one side of the
stringer, the horizontal flange having a slot
elongated transversely of the stringer; a 55
track rail carried by the horizontal flange
of the angle member; a bolt assembled with
the stringer and operating in the slot; a nut
on the bolt coacting with the horizontal
flange of the angle member; a second bolt 60
assembled with the stringer and passing
through the vertical flange of the angle
member; and a nut on the second bolt and
coacting with the vertical flange of the
angle member. 65
3. In a saw mill carriage track, a stringer;
an angle member comprising a horizontal
flange located on top of the stringer, and a
vertical flange depending at one side of the
stringer; a draw bolt connecting the vertical 70
flange with the stringer ; and a thrust-screw
threaded into the vertical flange of the angle
member and engaging the stringer; and a
track rail carried by the horizontal flange
of the angle member. 75
4. In a saw mill carriage track, a stringer;
an angle member comprising a horizontal
flange located on top of the stringer, and a
vertical flange depending at one side of the
stringer; a tension means connecting the 80
vertical flange with the stringer; a thrust
means carried by the vertical flange and co-
acting with the stringer; a connecting means
uniting the horizontal flange with the
stringer and having a limited lost motion 85
connection with the horizontal flange,
whereby the angle member may be moved in
one direction by the tension means, and be
moved in an opposite direction by the thrust
means; and a rail carried by the horizontal 90
flange and the angle member.
In testimony that I claim the foregoing as
my own, I have hereto affixed my signature
in the presence of two witnesses.
WILLIAM C. HEARD.
