I, ROBERT GATES PILKINGTON, a citizen of the United States of America,
residing at 4413 North Twenty-first Street, in the City of St. Louis and State of
Missouri, United States of America, Mechanical Engineer, do hereby declare the
nature of this invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
Figure 1 is a side elevation of apparatus embodying my invention, the horizontal
support and guide-bar being shown in transverse section and the power-shaft
broken off.
Figure 2 is a front elevation, looking in the direction of the arrow, Figure 1,
the horizontal support and guide-bar broken off at each side of the bracket-frame ;
and
Figure 3 is a horizontal section on the line - Figure 2, looking in the direction..
of the arrow on said Figure 2.
Like symbols refer to like parts wherever they occur.

My invention relates to means, for truing, dressing, and polishing the rolls of
metal-working mills, and has for its object the production of a simple and efficient
readily-portable apparatus. which may be employed to true, dress, or polish any
portion or the whole length of the roll without removing the roll from the housing,
disconnecting it from its power, or even stopping the rolls. The methods heretofore
commonly practised for this purpose have involved either the removal of the rolls
from their housings to a special lathe used for the purpose and their treatment
therein, or the disconnection of the usual power and the application of a slow
worm gearing, all of which involved heavy labor and loss of time, or the
application of concave clamp-blocks and abrading-powder to the rolls while in
position in the housing and driven by their usual gearing, which resulted in great
friction and frequently. developed so high heat as to interfere with the proper
working of the rolls, or the application to the rolls while in their housings of
special dressing devices of a cumbersome character and more or less slow in
operation. To overcome these several objections and secure a comparatively light,
simple, and efficient apparatus, rapid in its operation and which may be readily
applied to and removed from the roll-housings or equivalent supports adjacent to
the rolls to be dressed, I have combined with a suitable horizontally-adjustable
bracket-frame a rocking arm for the operative tool, said- arm being laterally
adjustable on its support, and such a construction or its equivalent. embodies one
feature of my invention. I have also combined with the rocking arm which

page_text: carries the power-shaft a rotating disk or face-plate which carries the bearings of
the abrading or polishing roll or like tool, whereby the tool may be reversed to
dress or polish the roll on opposite sides of the vertical center of the roll, and such
a construction or its equivalent embodies a second feature of my invention.
There are other minor features of invention, all as will hereinafter more fully
appear.
I will now proceed to describe my invention more fully, so that others skilled in
the art to which it appertains may apply the same.
In the drawings, 1 indicates a horizontal guide-bar of sufficient length to extend
between the housings of a metal-working mill and which may be detachably
supported thereon or upon any suitable independent supports therefor. Movable
longitudinally thereon is a bracket-frame 2, which may be provided with ears 3, in
which is journaled a pinion 4, controlled by a hand-wheel 5, said pinion 4 to
engage a rack on or in the side of the guide-bar 1, or any other well-known incans
of causing the bracket-frame 2 to traverse the guide-bar 1 may be adopted at the
will of the constructor. Projecting from the bracket frame 2 are other parallel
ears 66, slotted, as at 7, to provide for the reception and lateral adjustment of
a through-bolt 8, which forms the pivot of a rocking or vibrating arm 10 and
provides for the vibration of said arm, as well as for its adjustment across the
bracket-frame 2, to or from the axis of the roll to be dressed.
The rocking arm 10 is provided with a sleeve 11 at right angles to the bracket-
frame 2, (and the axis of the roll to be dressed or polished,) which constitutes a
bearing for the power-shaft 12.
12 indicates a shaft journaled in and projecting from the sleeve 11, to be driven
by any suitable power, preferably by a flexible connection or one which will allow
of the free vibration of arm 10 without detaching the power, and journaled on said
power-shaft at its inner end and abutting against the inner end of sleeve 11 is a
disk 13, provided with bearings 14 14 for the shaft 15 of the abrading or polishing
tool. The disk 13 being free to rotate on shaft 12 can be turned a half-revolution,
so as to bring the dressing or polishing tool on either side of the power-shaft, and
thus facilitate the dressing of a roll for its entire length or at any given point.
Upon the inner end of the sleeve 11 is a locking link and cam or equivalent
catch 16, adapted to engage the disk 13 by notches 17 or otherwise, and thus secure
the disk in the desired position.
Power is transmitted from power-shaft 12 to shaft 15 of the abrading or polishing
tool 18 by miter-gearing 19 or its equivalent.
The operation of the device is as follows: The lateral adjustment of the rocking
arms 10 to or from the axis of the roll to be dressed is accomplished by moving
its pivot bolt 8 to the desired position in slot 7, and the position of the abrading-
roll with relation to the vertical central line of the roll and power-shaft is
accomplished by rotating the disk 13 and locking it in position, after which the
arm is vibrated or rocked forward until it rests in position on the roll to be dressed,
after which the power is applied to shaft 12 and the abrading-tool is caused to
traverse the roll by shifting the bracket-frame 2 longitudinally of the guide-bar 1.
The construction herein before pointed out results in the production of a simple,
portable, easily manipulated, and very effective mechanism for dressing and
polishing metal-working rolls which have become bruised and defaced in use without
removing the rolls from their housings or deranging the gearing of the rolls, and
in a very expeditious manner as compared with the methods now commonly
practised.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manuer the same is to be performed, I declare that what I
claim, is :-
:-
1. In a machine for dressing or polishing rolls the combination with a suitable
support, of a laterally-adjustable vibrating arm, and a power-shaft and tool-shaft
journaled thereon; substantially as and for the purposes specified.

page_text: 2. In a machine for dressing or polishing rolls, the combination with an
adjustable bracket-frame, of a laterally-adjustable vibrating arm, and a power-shaft
and tool-shaft journaled on said arm; substantially as and for the purposes
specified.
3. In a machine for dressing and polishing rolls, the combination with a
vibrating arm, of a power-shaft journaled thereon, a disk loosely journaled on the
power-shaft and abutting against the vibrating arm, means for locking the disk to
the sleeve, and a tool-shaft journaled on the disk; substantially as and for the
purposes specified.
4. In a machine for dressing or polishing rolls, the combination with a movable
bracket-frame, of a laterally adjustable vibrating arm mounted thereon, a power-
shaft journaled on said arm, a disk journaled on the power-shaft, a tool-shaft
journaled on the disk, and means for locking the disk to the vibrating arm;.
substantially as and for the purposes specified.
