4 Claims.
Our invention relates to an apparatus for bur
nishing or cold rolling the journal portions of
axles and shafts. The principal object of the
invention is to adapt such apparatus for work
5 on journals of di?erent diameters. Another ob-'
ject is to prevent canting or skewing of such
apparatus with respect to the axis of the work
piece. The invention consists in the parts and
in the combinations and arrangements of parts
10 hereinafter described and claimed.
In the accompanying drawing wherein like

has a third work roller 9 rotatably mounted there
on equidistant from the two Work rollers 4 in the
base member. The apparatus also includes
means collectively indicated by the reference
numeral ID, for transmitting pressure through
the throat latch and its work roller to the journal
or other workpiece, all as more fully described.
in our said copending application.
Rigidly ?xed to the base member and project
ing from one end thereof is a mounting bar ll’ 10
of suitable size to ?t slidably in the tool post of
a lathe. Rigidly ?xed to the other end of the
base member and projecting therefrom in the
opposite direction is a steady or guiding bar l2
which is in substantial alinement with the 15
reference numerals indicate like parts wherever
they occur,

close to the axis of the journal or other work
axle or work piece shown in cross section;

I
1. An attachment for lathes which comprises a
10 frame and work rollers mounted therein, said at
tachment comprising a mounting bar adapted to
?t slidably in the tool post of a lathe, a second bar
diametrically opposite said mounting bar, and a
device attachable to said lathe for slidably sup
15 porting said second bar and for preventing tilting
of the apparatus transversely of its sliding move
ment, said second bar resting on said supporting
devices.
a frame and work rollers mounted therein, said
attachment comprising a mounting bar adapted
to ?t slidably in the tool post of a‘lathe, a second
bar diametrically opposite said mounting bar,
and a guiding and supporting device for said
second bar comprising spaced apart members at
tachable to the lathe carriage on, opposite sides
of said second bar, a block slidable‘ between said
members and having a groove therein adapted to
slidably support said second bar, and a support 10
for said block adjustably supported by said mem
bers, said support comprising a second block
slidable between said members below said ?rst
mentioned block, means for securing said second
block against movement, and a screw threaded 15
through said secondblock and supporting said,
?rst mentioned block.
4. A lathe attachment comprising a framework
2. An attachmentfor lathes which comprises _ having a mounting bar projecting outwardly
20 a frame and work rollers mounted therein, said
from one side of said framework in one direction 20
attachment comprising a mounting bar adapted
to ?t slidably in the tool post of a lathe, a second
and ‘adapted to ?t slidably in’ the tool post of a
lathe, a steady bar projecting outwardly from the
bar diametrically opposite said mounting bar,
opposite side of said frameworks in the opposite '
and a guiding and supporting device for said
direction in alinement with said mounting bar, a
25 second bar comprising spaced apart members at~
tachable to the lathe carriage on opposite sides
of said second bar, a block slidable between said
members and having a groove therein adapted to
slidably support said second bar, and a support
30 for said block adjustably supported by said mem
bers.
3. An attachment for lathes which comprises
Work tool on said framework, and means for sup
porting said steady bar and preventing canting
thereof from a plane at right angles to the axis of
the lathe, said steady bar resting on said sup-V
porting means.
