page_text: I, JAMES MUNTON of Maywood, in the County of Cook, in the State of Illinois,
one of the United States of America, Manufacturer, 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 improvements in the manufacture of tires from blooms.
My invention consists in combining with the shearing or cutting rolls a stop or
device to limit the approach of the cutting rolls towards each other so that the cutter
flanges of the rolls may come sufficiently close together to sever the annulus from the
bloom and at the same time prevent the cutters from injuring each other by being
forced together so that they strike or touch.
It also consists in combining with the vertical cutter rolls a pair of horizontal
edging rolls which may be brought into play the moment the shearing or cutting
operation is completed and the severed annulus removed, so that, in this way,
without removing the bloom from the mill or machine containing the cutter rolls,
the rolling operation and densification of the bloom may be continued as long as
the bloom retains sufficient heat. When the cutting operation is completed the cutting
flanges of the cutter rolls span, or almost span, the horizontal thickness of the
bloom, so that no more rolling can be done by the cutter rolls without causing the
opposing cutter flanges to meet or strike against each other. But by combining in
the same mill with the vertical cutter rolls a pair of horizontal edging rolls the rolling
and densification of the bloom may be indefinitely continued at the same heat that the
cutting is done; as the first effect of the horizontal or edging rolls, which bear against
the top and bottom faces of the bloom, is to diminish the vertical thickness of the
bloom and increase its horizontal thickness; and as soon as the horizontal thickness
has thus been increased sufficiently to prevent the opposing flanges of the cutter
rolls from meeting, the cutter rolls may be again brought into play and operated
simultaneously, or if desired alternately, with the edging rolls.
It also consists in combining with the cutter rolls and edging rolls two exterior pressure
rolls which tend in their operation to densify the bloom and roll the bloom backward or to
a smaller diameter, or to hold it at a fixed diameter under the action of the edging and
cutter rolls. These two exterior pressure rolls operate in conjunction with the:

page_text: exterior cutter roll. By this combination of the edging rolls and the exterior rolls
with the cutter rolls the rolling and densification of the bloom may he continued
to any desired extent at the same heat with the cutting operation and a bloom or
tire may thus be produced of much superior density, quality and texture, to the
ordinary hammered blooms; the fraying and injurious effects of hanımering are
entirely avoided. My invention also consists in mounting the inside vertical pressure
roll or its shaft on a separate slide from that which carries either or both of the
edging rolls, so that the downward or vertical pressure which operates the movable
edging roll will not increase the friction of the horizontal slide which carries the
inside vertical pressure or cutter roll, in cases where the edging and rolling
operation are being carried on simultaneously. My invention also consists in
mounting the two horizontal edging rolls and the hydraulic cylinder for operating
the movable or pressure edging roll in the same horizontally sliding frame upon
which the two exterior pressure rolls are carried, so that downward or vertical
pressure upon or between the edging rolls will not increase the friction of the
horizontally sliding frame, when the edging rolls and the exterior pressure rolls are
brought to bear simultaneously upon the tire, as is sometimes desirable.
My invention also consists in the novel devices and novel combinations of parts and
devices herein shown and described and more particularly pointed out in the claims.
In the accompanying drawing, which forms a part of this specification, and in
which similar letters of reference indicate like parts, Fig. 1 is a side elevation of
a machine or mill embodying my invention; Fig. 2 is a plan view; Fig. 3 is an
end view; Fig. 4 is a vertical longitudinal section; Fig. 5 is a cross section on
line 5-5 of figure 2; Figs. 6 and 7 are cross sections on lines 6-6 and 7-7 of
figure 2; Fig. 8 is a detail plan view; Figs. 9 and 10 are cross sections of the
tire, showing its form after the shearing operation is completed and after being
operated upon by the edging rolls, respectively, and illustrating the action of the
edging rolls to increase the horizontal thickness of the tire so that the flanges of the
cutting rolls will not meet. Fig. 11 is a vertical section showing ordinary box rolls
which may be substituted for the cutter rolls when the mill is being used for rolling
or finishing tires or rings.
In the drawing A represents the frame or bed of the machine, B and B₁ the cutter
rolls, CC the two exterior pressure rolls, and D, D' the horizontal edging rolls.
The cutter rolls B B₁ are, preferably, both furnished with cutter flanges or bevel
collars bb, the combined width of the flanges bb being equal to the horizontal thickness
of the bloom when the cutting operation is completed. The shaft B of the exterior
cutter roll B is journaled in stationary bearings B³ on the main driving frame A, and
it is driven from the main driving shaft E through the bevel gears E¹ and E'. Its
lower end is supported in a vertically and longitudinally adjustable cup-shape box or
a bearing B, the adjustment of which is effected by the wedge B and the screws B
and B'.
The shaft B8 of the movable cutter roll B' is journaled in bearings B, B10 on the
horizontal slide or carriage F which reciprocates on suitable guides F on the main
frame of the machine. The slide F is connected by rods or bars F with the piston F³
of the hydraulic cylinder F by which said slide F is reciprocated to force the cutter
roll B' against the bloom in opposition to the roll B.
The movement of the movable or pressure roll B' is limited by an adjustable stop f
so that the cutter flanges bb of the rolls B B' may approach sufficiently near to sever
the top portion or annulus of the bloom and still not quite meet and thus injure each
other. This stopf preferably consists of a screw threaded in the bar f which is
secured to the frame A by the rods ff. The screw is furnished with a hand
wheel for turning it and with a jam-nut f*.
The rolls C C and the edging rolls D D¹ are, preferably, all carried by, or mounted
upon, the same slide or carriage G. The slide G is reciprocated in suitable guides G¹
on the main frame of the machine by a hydraulic cylinder G³, the piston G³ of
which is connected to said slide. The vertical rolls C C and the horizontal roll D are
all three journaled directly on the slide G, but the vertically movable horizonal roll D¹

page_text: is journaled in suitable bearings D' on a vertically reciprocating supplemental slide H,
carried on the slide G.
The supplemental slide H is reciprocated in its guides H' on the sliding frame G by
a hydraulic cylinder H' and piston H³, the sten H* of the piston being connected to
the slide H. An adjustable stop limits the vertical movement of the edging roll D'
so that the tire or bloom may be edged down to any desired width. This stop h
preferably consists of a hand wheel nut on a screw threaded stem h¹ secured to the
piston H'. As the two opposing horizontal or edging rolls D and D¹ and the
hydraulic cylinder H3 for forcing them together, are mounted upon or carried by
the same main slide or carriage G, the pressure of the rolls D and D¹ will oppose
and neutralize each other and not be exerted against the guides G¹ of the slide G,
nor in any way increase the friction or the force required to reciprocate said slide G
on the main frame A.
The vertically non-inovable edging roll D is journaled in bearings D³ on the
reciprocating slide or carriage G and it is driven from the main driving shaft E
through the spur gears E³ E and shaft Es, which shaft is connected to the shaft D
of said roll D by a hollow shaft or sleeve D' having a spline d to permit the
reciprocating movement of the slide G and shaft D*.
The bearings CC of the two vertical rolls C C are mounted adjustably on the
slide G, so that they may be adjusted closer or farther apart as may be required in
rolling tires of different diameters. This adjustment is preferably effected by
furnishing the slide G with slots c in which the bearings or boxes C¹ fit, the position
of the boxes in the slots being adjusted by a series of thin blocks, plates or wedges e¹,
as indicated in Fig. 2.
KK are a pair of exterior guide rolls, mounted on adjustable slides K¹ K₁ which
reciprocate on transverse guides on the main frame A. The postion of the guide
rolls are adjusted by screws ¹¹ having sprocket wheels k³ ³, chains k³ k³ and
sprocket wheels on the shaft which is furnished with a hand wheel ke for
turning it.
LL represents the pipes by which the water or fluid under pressure is admitted to
the hydraulic cylinders F4, and H² from the pump and accumulator, customarily
employed in tire rolling mills for operating the pressure or movable rolls. Valves L¹
control the admission or escape of the fluid pressure as required.
The pressure rolls B B are removably secured upon their shafts so that they may
be removed and replaced by others when worn, or when required when rolling blooms,
tires or rings of different sizes and cross sections. The cutter rolls B B' may also be
removed and replaced by ordinary box or other rolls, such for example as shown in
figure 11, when it is desired to use the same mill for plain rolling as contradistinguished
from cutting and rolling.
The shaft of the movable or pressure roll B', and the shaft of the movable or
pressure edging roll D₁ are not driven except by friction with the tires or blooms
being rolled. In practice I have also not found it necessary to drive the vertical
rolls CC except with the tire.
In operation, the bloom, the top of which is to be cut off, is first placed in the mill
and the cutter roll B₁ forced up against it by the fluid pressure admitted into
cylinder F. As the cutting operation proceeds under the action of the cutter flanges
or collars bb, the rolls B B also roll the bloom, increasing its diameter and diminishing
its horizontal thickness. After the cutting operation is completed the annulus severed
from the bloom is removed with a crane, and then the slide G is advanced until the
edging rolls D D¹ are brought astride of the bloom, when the pressure is admitted
into the hydraulic cylinder H, and edging roll D₁ forced down upon the tire, the
pressure being relieved at this time upon the inside cutter roll B¹. After the edging
operation is continued for a while the horizontal thickness of the tire will be thereby
o increased, as indicated in figures 9 and 10, that the cutter roll B₁ may be again
brought into play without causing the cutter flanges to meet and injure each other.
At the same time with the edging operation the exterior pressure rolls CC may also
be brought into play to further densify the metal.

page_text: By mounting the hydraulic cylinders F and G at opposite ends of the machine
the slides which carry the various movable or pressure rolls may be more conveniently
operated. The connecting rods F' which connect the slide F with its operating
piston Fs pass astride of the stationary exterior roll B and its shaft.
When the mill or machine is being used for plain rolling or finishing the bloom
into a tire, plain rolls being substituted for the cutter rolls B B' on the shafts B2 B",
the stop is set so as to gauge the horizontal thickness of the tire by limiting
the movement of the inside pressure roll towards the exterior stationary roll. This
stop thus serves a very useful and important function, especially where the inside
pressure roll is operated by a hydraulic cylinder and piston, as contradistinguished:
from a screw. By means of this stop I am enabled to prevent any wavy irregularities
in the horizontal thickness of the tire which might otherwise be occasioned by the
hydraulic or somewhat elastic pressure which forces the inside pressure roll against
the tire.
By means of this stop in combination with the stop h which limits the movement
of the vertical pressure roll, the vertical thickness and the horizontal thickness both
of the tire may be accurately gauged and limited, so that the finished tire may be
made very uniform.
Having now particularly described and ascertained the nature of my said inven-
