portions 15 having the arcuate undercut
side walls 16 formed in the inner faces
thereof, said undercut side walls being
adapted to receive the tapering arcuate ends
5 of the plate 14'. Formed upon the upper
face of the plate 14' is an elongated en-
larged portion 17 which is provided with a
centrally arranged' groove 18 closed at one
end as shown at 19. Slidably mounted
10 upon the enlarged portion 17 is an. adjust-
able block 17' having undercut side walls 18'
adapted to receive the tapering side edges
of the enlarged portion 17. Formed inte-
gral with the under side of the block 17'
15 is an apertured lug 19' which is disposed
within the groove 18. A longitudinal screw
20 is mounted in a suitable bearing 21'
which is arranged within the closed end 19,
the inner end of said screw. being mounted
20 in the apertured lug 19' whereby the block
17' may be laterally adjusted with respect
to the periphery of the locomotive wheel.
Secured to the outer end of the screw 20 is
a handle member 22' whereby the screw
25 may be readily manipulated to adjust the
block 17'.
The elongated plate 14' is provided at one
end and upon the under surface thereof with
the serrations 19a which are adapted to be
30 engaged by the worm gear 20a mounted
upon the transverse shaft 21a whereby the
plate 14' may be readily rotated. A suitable
handle member 22a is mounted upon the
cuter end of the shaft 21a by means of which
35 the shaft may be readily rotated to adjust
the plate 14'.
The tool standard 23 is carried by the
central portion of the block 17' and adjust-
ably mounted therein is a shank 24, said
40 shank being held in various adjusted posi-
tions by means of the set screw 25 carried by
the standard 23. Adjustably secured within'
the outer end of the shank 24 is a cutting
knife 26, which is held in various adjusted
45 positions by means of the set screw 27. Thus
as the wheel is turned by means of the cor-
rugated rollers 11, the cutting knife 26 can
be readily adjusted to various positions so
that the uneven surface of the tread of the
50 wheel may be readily evened off.
Secured to one end of the bearing plate 13
and extending upwardly from the body in a
substantially vertical position is a brace
member 28, the upper end of which is se-
55 curely bolted by means of the bolts 29 to one
of the longitudinal arms of the bracing
frame 30. Securely bolted to the frame 30 is
a supporting plate 31.
The numeral 32 indicates the trunnion of'
60 a locomotive drive wheel having a brass
bearing 33 arranged upon the upper side
thereof and a' supporting block 34 is ar-
ranged beneath the same and, spaced from
the trunnion by means ,of the babbitt 35,which forms a suitable bearing for the trun- 65
nion. 32. Arranged between the plate 31 and
the block 34 are the wedge members 36
which are driven in securely to rigidly sup-
port the trunnion.
In Fig. 1, we have illustrated suitable 70
means for automatically adjusting the block
17' which carries the cutting tool 26. This
means comprises a universal shaft 37 mount-
ed in suitable bearings 38 which are secured
to the side of the body member 1. Mounted 75
upon the shaft 37 is a gear 39 which is
adapted to mesh with the worm gear 40
mounted upon one of the shafts 10. Mount-
ed upon the upper end of a shaft 37 is a
worm gear 41, said worm gear meshing with 80
a suitable gear 42 mounted upon the outer
end of the screw 20. When the block 17' is
in a position wherein the apertured lug 19' is
at the outer end of the screw 20, the worm
gear 41 is engaged with the gear 42 by means 85
of the bell crank lever 43 which is mounted
upon the end of the bearing plate 13. From
the above, it will be seen that the block 17'
may be readily and quickly adjusted by en-
gaging the worm gear 41 with the gear 42. 90
From the above description taken in con-
nection with the accompanying drawings,
it will be readily apparent that we have pro-
vided an improved machine for turning and
truing locomotive drive wheels at one opera- 95
tion.
In the practical use of our invention, the
locomotive wheel is first jacked up clear of
the track and the body member 1is then se-
curely clamped to the tread of the wheel be- 100
neath one side of the wheel, power is then
supplied to the shaft 6, which in turn will
transmit motion to the corrugation rollers 11
to rotate the wheel. The knife 26 is then
moved toward the periphery of the wheel 105
and' adjusted to any desired angle so that the
uneven surface of the tread of the wheel may
be readily removed therefrom.
It will be readily apparent that in using
our improved machine, the body 1 is securely 110
clamped to one of the rails beneath one of
the driving wheels of the locomotive. After
the uneven surface of the tread of this wheel
has been removed, the body is released from
the track and placed beneath the wheel upon 115
the opposite side of the locomotive and
readily secured to the track rail to hold the
same against movement, while removing the
uneven surface of the second wheel. It will
also be apparent that the device is extremely 120
simple in construction and at the same time
can be manufactured at a comparatively low
cost.
While we have shown and described the
preferred form of our invention, it will be 125
obvious that various changes in the details of
construction and in the proportions may be
resorted to for successfully carrying our in-
