and Company, of 166, Fleet Street, in the City of London, Patent Agents,
for the Invention of "IMPROVEMENTS IN ROLLING MILLS, WHICH IMPROVE-
MENTS ARE APPLICABLE ALSO TO MILLS OR MACHINERY USED FOR BREAKING,
PULVERIZING, STRETCHING, FLATTENING, POLISHING, OR OTHER ANALOGOUS
Purposes." A communication from abroad by Andreas Mechwart, of the
Firm of Messrs. Ganz and Company, of Buda Pesth, in the Kingdom of
Hungary, Engineers.
Sealed the 10th April 1879, and dated the 18th November 1878.
PROVISIONAL SPECIFICATION left by the said Thomas James Smith at the
Office of the Commissioners of Patents on the 18th November 1878.
THOMAS JAMES SMITH, of the Firm of Robertson, Brooman, and Company, of
166, Fleet Street, in the City of London, Patent Agents. "IMPROVEMENTS IN
ROLLING MILLS, WHICH IMPROVEMENTS ARE APPLICABLE ALSO TO MILLS OR
MACHINERY USED FOR BREAKING, PULVERIZING, STRETCHING, FLATTENING,
POLISHING, OR OTHER ANALOGOUS PURPOSES." (A communication from abroad
by Andreas Mechwart, of the Firm of Messrs. Ganz and Company, of Buda Pesth,
in the Kingdom of Hungary, Engineers.)
In the Specification of the Patent, No. 563,78, granted to my foreign corre-
spondent for "Improvements in Machinery Used for Granulating and Pulverizing
Grain and Seeds," rotary antifriction pressure rings are described and shown, these
rings embracing the outer axles of the roller mill and revolving with them, thus
annihilating by their tension the pressure exerted on the axles of the rollers, and
thereby also the friction in the bearings.

page_text: Now the object of the present Invention is the application of rotary anti-friction
pressure rings similar to those described in the Specification above referred to, to
all kinds of rolling mills, and to mills or machinery used for breaking, pulverizing,
stretching, flattening, polishing, or other analogous purposes.
In carrying my Invention into effect the anti-friction rings revolve on and with
the coupling boxes fixed on the end of the axles coupling with the next set of
rollers.
The tension is obtained by means of levers pivoted at one end to the frame or
foundation of the mill or machine, these levers being provided with rollers bearing
on the inner periphery of the anti-friction ring.
The opposite end of each lever may be provided with a toothed quadrant taken
into by a worm, the shaft of which is provided with a hand wheel to regulate the
desired pressure.
It is obvious that my Invention is susceptible of modification to suit the different
varieties of mills or machines to which it may be applied, and I wish it to be
understood that I do not limit myself to the precise arrangement herein before
described, but claim as novel the application to roller mills and to mills or machinery
used for breaking, pulverizing, stretching, flattening, polishing, or other analogous
purposes of anti-friction pressure rings similar to those described in the Specification
of the Patent, No. 563,78..
