LETTERS PATENT to Walter Brierley, of Halifax, in the County of York, and
Blackburn, in the County of Lancaster, Patent Agent, for an Invention of
"IMPROVEMENTS IN APPARATUS FOR JUMPING' TIRES OF LOCOMOTIVES AND
RAILROAD CARS." A communication from abroad by Lewis Mohn, of Breslau,
Kingdom of Prussia, German Empire.
PROVISIONAL SPECIFICATION left by the said Walter Brierley at the Office
of the Commissioners of Patents on the 7th July 1880.
WALTER BRIERLEY, of Halifax, in the County of York, and Blackburn, in the
County of Lancaster, Patent Agent. "IMPROVEMENTS IN APPARATUS FOR
'JUMPING' TIRES OF LOCOMOTIVES AND RAILROAD CARS." A communication
from abroad by Lewis Mohn, of. Breslau, Kingdom of Prussia, German Empire..
The object of my Invention is to "jump" the tire of a locomotive or of railroad
cars by using the expansion of the tire during the heating thereof.
I attain this object by mechanism and means as follows:-The tire to be jumped
is placed in the fire, and after being somewhat heated frames are applied which
transfer the pressure of the well heated tire to lesser heated jumping ring, put in
so that they act only after strong heating of the tire. Through the thickness of an
adjusting ring all small differences in the diameter of the tire are equalized. The
tire frames, jumping- rings, and adjusting rings or supported over or above a
furnace, and after putting on a cover a blower is brought to work, and the tire is
heated to a degree proportional to the degree of jumping necessary.
When this is done the blower is stopped and the cover taken off'; the tire becomes
cool without using other means, so that the frames can be taken away and the tire
taken out for cooling. The heating of the tire may be done also by means of gas,
or a fire put around the tire, instead of the furnace as described.

WALTER BRIERLEY, of Halifax, in the County of York, and Blackburn, in the
County of Lancaster, Patent Agent. "IMPROVEMENTS IN APPARATUS FOR
JUMPING TIRES OF LOCOMOTIVES AND RAILROAD CARS." A communication
from abroad by Lewis Mohn, of Breslau, Kingdom of Prussia, German Empire.
The object of my Invention is to "jump" the tire of a locomotive or of railroad
cars by using the expansion of the tire during the heating thereof.
I attain this object by mechanism and means as follows:-The tire to be jumped 1
is to be placed in the fire, and after being somewhat heated frames are applied
which transfer the pressure of the well heated tire to lesser heated jumping ring,
put in so that they can act only after strong heating of the tire. Through the
thickness of an adjusting ring all small differences in the diameter of the tire are
equalized. The tire frames, jumping rings, and adjusting rings are supported over 1
or above a furnace, and after putting on a cover a blower is brought to work, and
the tire is heated to a degree of proportional to the degree of jumping necessary.
་
When this is done the blower is stopped and the cover taken off; the tire becomes
cool without using other means, so that the frames can be taken away and the tire
taken out for cooling. The heating of the tire may be done also by means of gas,
or a fire put around the tire, instead of the furnace as described.
Such being the nature and object of this the said Invention, I will now describe
the same in detail, and have hereunto annexed the Sheet of Drawings illustrating
the apparatus employed. The object of the Invention is to jump and set up the
tires of locomotives or railroad cars by utilizing the expansion of the tire during
the heating.
The mechanism employed is illustrated in the accompanying
Drawings, in which,-
Fig. 1 is a vertical section, and Fig. 2 a plan view, one half having cover removed.
Similar letters refer to similar parts throughout the several views.
The tire A to be jumped is introduced to the fire cold, or by preference after
some heating; then the frames B, 'which have to transfer the pressure of the
further heated fire to the slightly heated jumping ring C, are put in so that they
lay on tightly only after further heating of the tire; through the thickness of the
adjusting ring D.all small differences in the diameter of the tire are equalized.
After putting on the cover E the blower as F is brought to work, and the tire
is to be heated to a degree proportional to the jumping requisite.
When this is done the blower is stopped and the cover E taken off; the tire is
allowed to cool so that the frames B can be taken away and the tire taken out for
entire cooling.
The heating of the tire may be done also by means of gas or fire put around the
tire, instead of the shaft furnace shown in the Drawings.
Having thus fully described the nature and particulars of this said Invention,
together with the manner in which the same is to be performed or carried into
practical effect, I would have it understood that I claim as my Invention (and
desire to secure by Letters Patent), the combination and use in combination of the
apparatus described, whereby the expansion of the heated tire is utilized for
jumping the same, as described and illustrated by Drawings.

and as fully described in the above Specification.
In witness, whereof, I, the said Walter Brierley, have hereunto set my hand
and seal, this First day of January, in the year of our Lord One thousand
eight hundred and eighty one.
