improvements in Machines for Kolling Blooms for the Manufacture
of Wheel Tires.
I HENRY HARRIS LAKE of the firm of Haseltine Lake & Co. Patent Agents,
Southampton Buildings, in the County of Middlesex, 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 :-
My invention relates to the manufacture of blooms by casting them of a greater
thickness than required, and then cutting off an annulus at the top of the bloom to
remove the imperfect portion of the bloom.
.
My invention consists of a bloom or tire rolling machine wherein the rolls are
furnished with cutter flanges for severing the annulus containing the sediment, blow
holes and other imperfections which rise to the top portion of the bloom as it is cast.
It also consists in providing the rolls of such machine with an annular groove for the
flange of the bloom or tire so as to partially form, roll and shape the same at the same
time the cutters remove the imperfect top portion of the annular casting.
In the accompanying drawing which forms a part of this specification,
Figure 1 is a partial plan view of a bloom or tire rolling machine embodying my
invention, and
Figure 2 is an enlarged elevation of the rolls.
In the drawing A represents the bed-plate and A' the bed or supporting rolls for
the bloom. B represents the bloom produced from the annular casting by cutting
off the imperfect top portion 6 therefrom. C represents the exterior driven roll and D
the interior movable roll. The rolls C and D are each furnished with a cutter or
flange c, d, at their upper ends, by which the annulus 6 is severed from the top portion
of the bloom. At their lower ends the rolls C, D are each provided with flanges c¹, d
which serve to support and enclose the lower edge of the bloom. The large driven
roll C is also furnished with an annular groove d' which serves to form a partial flange

the bloom. This groove also serves to keep the bloom down or in place upon
the flanges as it is rolled. The rolls C, D, are roughened upon their surface as well
as the upper or conical surface of the cutters c, d. The beveled flanges or cutters c, d,
are preferably cast integral with the rolls themselves. The cutter flanges c, d should
not be made long enough to reach entirely across the face or through the bloom until
after the bloom is reduced in size and increased in diameter by the rolls. The
collars c, d, should just about equal the cutter flanges c, d in depth, so that as the bloom
diminishes in size or thickness under the action of the rolls, the cutters may come
nearly or quite together and completely sever the imperfect annulus 6 from the bloom.
The rougness or corrugations upon the surface of the rolls and cutter flanges cause the
bloom to drive better in the rolls.
The mechanism for driving the roll and for setting the roll D up against the
roll C and the other parts of the rolling machine are, or may be, of the ordinary and
well known construction employed in tire rolling machines, and does not need to be
here described or shown in detail, as the same is well known to those skilled in
the art.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, as communicated to me by my foreign
correspondent I declare that what I claim is :
1st. A tire or bloom rolling machine having a pair of rolls furnished with cutter
flange for severing the top portion from the annular casting or bloom as it is rolled,
substantially as specified.
2nd. In a tire rolling machine, the rolls B and C furnished with beveled cutter
flanges c, d, and collars c¹, d¹, said roll C having also an annular groove d² for the
flange of the bloom or tire, substantially as specified.
