PROVISIONAL SPECIFICATION.
A New or Improved Means of Heating the Rolls used in Rolling
Mills, and Apparatus therefor.
I, ROBERT JOHN FULTON, of 17, Rowchester Street, off Gallowgate, Glasgow,
Steelworker, do hereby declare the nature of this invention to be as follows:-
This invention relates to a new or improved means of heating the rolls used in
rolling mills, and apparatus therefor.
The invention consists of a cylindrical case, made in two halves, which is placed
over the roll to be heated, so that it lies against the inner surface of the cylindrical
case. These two halves are then bolted together. To the upper portion of cach
half of the cylindrical case there is fitted a pipe or tube which meet together
and are joined to another pipe. This pipe is then connected to a pipe leading
from a steam boiler. The steam is then allowed to pass into each half of the
cylindrical case through the pipes, when the roll is soon heated up to a uniform
degree. To throw off any exhaust or condensed steam, each half of the cylindrical
case is provided with a tap or cock.
Each half of the upper portion of the cylindrical case is also provided with a
catch, so that it can be easily moved about.
Dated this 25th day of March 1890.

COMPLETE SPECIFICATION.
A New or Improved Means of Heating the Rolls used in Rolling
Mills, and Apparatus therefor.
I, ROBERT JOHN FULTON, of 17, Rowchester Street, off Gallowgate, Glasgow,
in the County of Lanark, North Britain, Steelworker, 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 :-
This invention relates to a new or improved means of heating the rolls used in
rolling mills, and apparatus therefor.
The invention consists of a cylindrical case, made in two halves, which is placed
over the roll to be heated so that it lies against the inner surface of the cylindrical
casc. These two halves are then bolted together. To the upper portion of each
half of the cylindrical case there is fitted a pipe or tube which meet together and
are joined to another pipe. This pipe is then connected to a pipe leading from a
steam boiler. The steam is then allowed to pass into each half of the cylindrical
case through the pipes, when the roll is soon heated up to a uniform degree. To
throw off any exhaust or condensed steam each half of the cylindrical case is
provided with a tap or cock.
Each half of the upper portion of the cylindrical case is also provided with a
catch so that it can be easily moved about.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended an explanatory sheet of drawings, in the several
figures of which corresponding parts are marked with the same letters of reference.
Figure 1 is an elevation.
Figure 2 is a sectional elevation; and,
Figure 3 is an end view.
A, A are the two halves of the cylindrical case, which are placed over the

page_text: roll B to be heated, which is supported by any suitable standards or rests G, G,
and the two halves are then bolted together by bolts C, or in any other convenient
manner. When the two halves of the case are brought together the pipes D, D,
which are fixed to the top of each half, fit into one another, and meet another
pipe E leading from the steam boiler or other source from which the steam is
obtained. When this is done, the steam is then allowed to pass from the boiler or
other source of supply through the pipe E to the pipes D, D, and then into the
two halves A, A of the case, when the roll is soon heated up to a uniform
degree.
In order to throw off any exhaust or condensed steam, I provide each half A, A
of the case with a tap or cock F, F.
I also provide cach half of the case with any suitable catch H, so that the case
can be easily removed from one place to another.
In order to retain the heat in the case, I place a sheet of felt or other suitable
material round the outer surface of it, and over that again a covering of wood.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what 1
claim is :-
1. Heating the rolls used in rolling mills, substantially as described.
2. The cylindrical case with its appurtenances for heating the rolls used in rolling
mills, substantially as described and shown on the accompanying sheet of
drawings.
