Year: 1876

page_text: LETTERS PATENT to William Shepherd Williamson, of Mortlake House,
Congleton, in the County of Chester, Iron Manufacturer, for the Invention of
"IMPROVEMENTS IN THE TREATMENT OF THE REFUSE FROM IRON FURNACES,
AND IN APPARATUS TO BE EMPLOYED IN SUCH TREATMENT."
Sealed the 23rd March 1877, and dated the 2nd October 1876.
PROVISIONAL SPECIFICATION left by the said William Shepherd Williamson
at the Office of the Commissioners of Patents on the 2nd October 1876.
WILLIAM SHEPHERD WILLIAMSON, of Mortlake House, Congleton, in the County
of Chester, Iron Manufacturer. ." IMPROVEMENTS IN THE TREATMENT OF THE
REFUSE FROM IRON FURNACES, AND IN APPARATUS TO BE EMPLOYED IN SUCH
TREATMENT."
My Invention relates to a former Invention, for which Provisional Protection,
bearing date the Fifteenth day of May in the current year has been granted to me.
In the said former Invention I ran slag from iron furnaces into a tank of water
in order to disintegrate the slag, and I withdrew the gravel or disintegrated slag by
means of an elevator or chain of buckets.
According to my present Invention I discharge the cinders and other refuse
discharged or removed from the furnace into a tank or cistern of water in addition
to the slag, and I cause the elevators which raise the matters out of the said tank
or cistern to discharge the said matters into a shute which conveys them between
crushing rollers which break up any masses of cinders or refuse which have not
been sufficiently disintegrated by the water, and which tend to reduce the matters
to a comparatively uniform condition as regards the sizes of the pieces. If con-
sidered desirable the matters may be screened after leaving the said rollers.
When applied to a pair of blast furnaces I form or place the tank made of wrought
iron or other suitable material between the two furnaces, so that the refuse can be
readily discharged into the said tank. The matters so treated, which would
otherwise be sources of great loss and destruction of agricultural land are suitable
to be used in lieu of gravel in the formation of roads, and as ballast for use in the
formation and maintenance of railroads, and in the preparation of concrete, and for
other useful purposes.

to me.
According to my present Invention I discharge the cinders and other refuse
discharged or removed from the furnace into a tank or cistern of water in addition
to the slag, and I pass the said cinders and refuse between crushing rollers which
break up any masses of cinders or refuse which have not been sufficiently disinte-
grated by the water, and which tend to reduce the matters to a comparatively
uniform condition as regards the sizes of the pieces.
When applied to a pair of blast furnaces I place the apparatus between the two
furnaces so that the slag and refuse can be readily discharged into the tank or tanks.
And in order that my said Invention may be fully understood I have appended
hereunto a Sheet of Drawings made to a scale of about three-eighths of an inch to
the foot and marked with letters of reference, corresponding marks indicating the
same parts in the various Figures.
Referring to the said Drawings, Fig. 1 represents an elevation, partly in vertical
section, of the apparatus arranged to be used in connection with two blast furnaces,
and Fig. 2 is a plan of the said apparatus. In the said Figs. A, A, are two
cisterns made of wrought iron or other suitable material, into which the cinders
and other refuse matters from the furnace are thrown; B, B, are two sets of
crushing rollers, which are mounted over a tank C, into which the slag is run; and
D is an elevator for removing the matters from the last named tank. The said
crushing rollers are mounted in suitable framings, and are provided with connecting
gearing a and with driving gearing b, by means of which the rollers receive motion
from the crank shaft c of an engine of suitable construction. In the example the
driving pinions are arranged to slide upon the said crank shaft in order that one or
the other of the pairs of rollers may be thrown out of action, but other arrange-
ments may be employed for effecting the same object. Each pair of rollers is
provided with a hopper D; in the plan one hopper is represented in position. The
bottoms of the side wings of the tank C, that is, the parts over which the roller
frames are seated should, by preference, slope towards the central part in order
that the matters may be directed towards the elevator. When in operation tho slag is
run from the furnaces into the tank C, and the cinders and refuse are thrown or
conveyed into the cistern A. At intervals the contents of the said cisterns are
shovelled out into the hoppers of the crushing rollers, and are thereby crushed and
fall into the tank C, which is supplied with water as in my said former Invention.
The matters comminuted by the action of the water and of the crushing rollers
are withdrawn from the tank C by the elevator, which, if required, may discharge
the said matters into railway trucks or into carts. The matters so treated, which
would otherwise be sources of great loss and destruction of agricultural land, are
suitable to be used in lieu of gravel in the formation of roads and as ballast for use
in the formation and maintainance of railroads and in the preparation of concrete,
and for other useful purposes.
Having now fully set forth and indicated the nature of my said Invention and
the manner in which I carry the same into practical effect, I would have it to be
understood that I claim the apparatus and arrangements substantially as and for

In witness whereof, I, the said William Shepherd Williamson, have hereunto
set my hand and seal, this Twenty-seventh day of March, in the year of
our Lord One thousand eight hundred and seventy-seven.
