the bearing surface is increased approxi-
mately one-third.
The shoe 7 and wedge 8 having no flanges
to bear against the pedestal, the side thrust
5 is communicated transversely from the
flanges 21 to shoe 7 and wedge 8 and then to
retaining plates 9 and 10, which transmit it
to the inner sides of the pedestals through
screws or bolts 22, 22, which hold also the
10 wearing plates 15 in position. With the im-
proved construction, the box A and all co-
operating parts are removable without re-
moving the pedestal tie-bar D. An exte-
riorly threaded sleeve 11 is provided for ad-
15 jousting the wedge 8. The sleeve 11 operates
through the pedestal tie-bar D and is pro-
vided with a lock-nut 16 by which the sleeve
11 may be fixed at the desired height in the
pedestal tie-bar D. A T-headed bolt 18 is'
20 provided for adjusting the wedge. This
bolt 18 is of such design that it can be re-
moved through the opening in the pedestal
tie-bar D through which the sleeve 11 oper-
ates. After the sleeve 11 is fixedly adjusted
25 the wedge is then adjusted by the bolt 18
and secured in place by a nut -23. The
wedge 8 has a recess for the head 19 of the'
bolt 18 and a semi-elliptical bearing plate
or washer 17 is provided so that the wedge
80 8 can be perfectly alined on the sleeve 11,
the plate being placed between the end of
the sleeve 11 and the wedge. The wedge 8
and the shoe 7 may be removed for relining
by removing the bolt 18 and the plates 9
35 and 10 without disturbing the pedestal. The
shoe can be removed by simply removing
the bolts from plate 9 and swinging the
same on its hinge. without disturbing the
plate 10 or wedge 8 and the wedge 8 can be
40 removed by removing the bolts from plate
10 and swinging the same on its hinge with-
out disturbing the shoe 7.
In the variation shown in Figs. 8 to 11 in-
clusive, the shoe 7 and wedge 8 are held in
45 place respectively by plates 5 and 6 and the
lateral thrust of the wheel is taken up by
the flanges 12. The construction is other-
wise the same as that shown in the previous
views. The box B cannot be removed with-
60 out removing the pedestal tie-bar D. The
cellar 3 can be released and tilted forward
or outward for the purpose of repairs with-
out removing the box B. The cellar 3 is in-
terchangeable in boxes A and B. The wear-
55 ing plates 15 are common to both construc-
tions of boxes A and B. These wearing
plates provide a greater thrust bearing for
the driving boxes and may be renewed at
any time without disturbing the frame 1
8o and they make the repairing of the coper-
ating parts more readily accessible.
Having fully described my invention,
what I claim as new and desire to secure by
Letters Patent, is,-
65 1. A knock down driving box for locomo-tives having a removable cellar and a re-
taining screw therefor, a flangeless shoe and
a flangeless wedge for. centering the driving
box, and retaining plates .for said shoe and
wedge and constituting the means of taking 70
up the lateral thrust.
2. A driving box for locomotives compris-
ing a box having flanges on the hub side
thereof, a shoe and a wedge for centering
said box, and bearing plates retaining said 75
shoe and wedge in place and taking up the
lateral thrust of the wheel.
3. A driving box for locomotives compris-'
ing a box having flanges on the hub side
thereof, bearing plates for taking up the 80
lateral thrust of the wheel, and a flangeless
shoe and a flangeless wedge retained in place
by said flanges and bearing plates for cen-
tering the box.
4. In a- driving box for locomotives, pro- 85.
vided with a frame, a box mounted in said
frame, a flangeless shoe and a flangeless
wedge for centering said box in the jaws of
said frame, and bearing plates attached to
said frame for retaining said shoe and 90
wedge in place and for taking up the lateral
thrust of the wheel.
5. In a driving box for locomotives, pro-
vided with a frame, a box mounted in said
frame, bearing plates attached to said frame 95
for taking up the lateral thrust of the wheel,
and a flangeless shoe and a flangeless wedge
held in place by said bearing plates for cen-
tering said box in the jaws of said frame.
6. In a driving box for locomotives 'pro- ioo
vided with a frame having a recess therein,
a box mounted in said frame and removable
horizontally through said frame, bearing
plates attached to said frame for taking up
lateral thrust of the wheel, and a flangeless 105
shoe and a flangeless wedge for centering
said box in the jaws of said frame held in
place by bearing plates.
7. In a driving box for locomotives, pro-
vided with a frame, a box mounted in and no
removable horizontally through said frame
and having flanges on the hub side thereof,
hinged bearing plates attached to said
frame, and a shoe and a wedge for center-
ing said box in said frame. 115
8. In a locomotive driving box, provided
with a frame, a box mounted in and remov-
able horizontally through said frame, bear-
ing plates attached to said frame and retain-
ing said box in place, a shoe and a wedge for 120
centering said box in said frame, an adjust-
ing sleeve operating through said frame for
varying the position of said wedge, and a
rod operating through said sleeve for fixing
said wedge in position. 125
9. In a locomotive driving box, provided
with a frame, a box mounted in said frame,
a shoe and a wedge for centering said box
in said frame, an exteriorly threaded sleeve
operating through said frame for adjusting 130
