COMPLETE SPECIFICATION.
Improvements in Grinders and Dressers for Metallic Rolls.
I, WILLIAM EDWIN HARRIS, of Niles, in the County of Trumbull, State of
Ohio, one of the United States of America, Metal Worker, 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, reference
being had to the accompanying drawings, forming part of this Specification and to
the reference numbers marked thereon that is to say :-
My present invention consists of certain novel features of construction that will
be hereinafter fully described and specifically pointed out in the claims.
Figure 1 is an end elevation of a pair of mill rolls having the dresser or grinder
applied thereto.
Figure II is a side elevation of the same.
Figure III is a modification of the means for applying the dresser or grinder.
Figure IV is a detail cross section of the dresser or grinder holder showing the
cooling chamber, and
Figure V is a detail plan view of the holder with the dresser or grinder
removed.
1 and 2 represent the rolls which may be journalled in any suitable frame, and
3 the dressers or grinders.
The dressers or grinders 3 are composed of a suitable grinding face 4 dovetailed
into a holder 5 which is formed with a cooling chamber 6 and suitable inlet and
exit tubes 7, 8 for admitting and withdrawing a cooling medium to and from the
chamber 6. This latter construction is to keep the grinder or dresser face 4 cool
while at work. 9 and 10 (see Figures IV and V) represent strengthening rods for
the dresser 4.
The holders and dressers which are concave where they fit around the rolls are
held to the said rolls by means of the rods 11 and nuts 12. These rods as will be
seen from Figures I and II are passed through the holders at their ends and are
held therein by the nuts 12. By this construction the dressers or grinders can be
made to bear more or less on the surface of the rolls. 13 represents a pair of
bandles formed on the upper holder to facilitate the handling of the device when it
is desired to move it to a different part of the surface of the rolls.
In Figure III I have shown a modification of the means for adjustably holding
the dresser or grinder to the roll. In this instance the holder is suitably pivoted
on a bar 14 conveniently located on the frame in which the rolls are journalled, and
it is provided at its outer end with the weight 15.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
1. In a mill roll dressing device, the combination of the rolls, and the dressers
or grinders provided with a cooling device adjustably held to said rolls, substantially
as shown and described.
2. In a mill roll dressing device, the combination of the upper and lower roll,
a dresser or grinder for each of said rolls mounted within a holder formed with a
cooling chamber, and suitable means for adjustably connecting said holders,
substantially as and for the purpose set forth.
3. In a dresser for mill rolls, the combination of the roll, and a dresser mounted

page_text: within a suitable holder formed with a cooling chamber and provided with
reinforcing rods or strips for the dresser, substantially as shown and described.
4. In a mill roll dressing device, the combination of the rolls, a dresser or
grinder for each roll, mounted in a holder having a cooling chamber, and an adjust-
able connection between said holders consisting of rods passing through the holders
and secured therein by nuts, substantially as and for the purpose set forth.
5. In a mill roll dressing device, the combination of the rolls having dressers or
grinders adjustably held thereto; and suitable handles attached to said dressers or
holders, substantially as and for the purpose set forth.
いこ Dated this 19th day of March 1895.
