COMPLETE SPECIFICATION.
Improvements in the Manufacture of Tires for the Wheels of
Railway and other Vehicles and in Apparatus therefor.
1, JAMES MUNTON, residing in Maywood, in the County of Cook, in the State of
Illinois, 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 :-
The object of my invention is to provide means for rolling or forming two or more
rings or tires simultaneously from a single annular ingot and to improve the general
character, of the machine in respect to its efficiency, durability, ease and rapidity of
operation.
One feature of my improvement consists in mounting the guide rolls which are
adjacent to the main vertical driven roll and to the inside vertical pressure roll on
laterally moving slides which are adjusted or moved out automatically as the tire or
ring increases'in diameter by means of a slide carrying two exterior pressure rolls
diametrically opposite, the main exterior driven 1oll. This latter slide is, furnished
with angle grooves or cams which actuate levers pivoted to the laterally moving slides
upon which the guide rolls are mounted.
Another feature of my improvement consists in making the guide-rolls and the
two exterior pressure rolls vertically adjustable so that by adjusting one or other of
the guide rolls up or down, the tendency of the tire or bloom being rolled to
climb up may be counteracted and the same caused to run truly in a horizontal
plane.
To adapt the machine to roll two or more rings or tires simultaneously'l provide
the slide which carries the inside vertical pressure roll with a vertically swinging
hanger furnished with a box or bearing for the upper end of the inside pressure roll
so as to give the upper end of this pressure roll or its shaft. the requisite support to
roll two or more rings, or one very wide ring bloom. This vertically swinging
hanger is turned back out of the way when the bloom or rings are being placed in or
taken out of the machine by means of a small hydraulic cylinder or other suitable
engine or power.
Another feature of my improvement consists in, mounting the inside pressure roll
so that it revolves upon its shaft, the shaft being made non-rotary. By this means
I am enabled to overcome the difficulty arising from the scales, dropping.down into
the bearings of the inside pressure roll shaft.
Other features of my improvement consist in the novel devices and, novel com-
binations 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, iike parts, Fig. 1 is a plan view of a tire
rolling machine embodying my invention; Fig. 2, is a side elevation; Fig. 3 is a
partial central vertical section on line 3-3.of Fig. 1; Fig. 4 is a partial horizontal
section on line 4-4 of figure 2; and Figs. 5 and 6 are vertical cross sections on
lines 5-5 and 6-6, respectively, of figure 1.
In the drawing A represents the bed or frame of the machine. 'B is the main exterior
vertical driven roll, C the inside vertical pressure roll, 'D D the automatically actuated
or adjusted guide rolls adjacent thereto, E the horizontal driven edging roll, F the
vertically movable or pressure, edging roll, and G:G the two exterior pressure rolls
diametrically opposite the main exterior driven. roll B.
The roll B or its shaft B is driven from the main driving shaft H by the beveled
gears hand, h¹.
The horizontal driven edging roll E or its shaft E' is driven 'from the driving

page_text: shaft H by the spur gears h³, and the sleeve h* which is splined to the shaft E¹ so
that the said shaft may reciprocate in said sleeve.
The vertical inside pressure roll C is journalled or revolves loosely on its non-
revolving shaft C which is mounted upon a sliding carriage K, which reciprocates in
suitable guides K' on the frame of the machine and is actuated by a hydraulic
cylinder K² and piston K³. The slide or carriage K has a bearing k for the lower
end of the shaft C, and a bearing or support k¹ for the middle portion of the shaft,
and a pivoted or vertically movable hanger 2 having a bearing or support k³ for the
upper end of the shaft C¹. The hanger is preferably pivoted to the slide K so
that it may swing vertically out of the way of the tire or bloom which is being
placed in or taken out of the machine. The pivoted hanger 42 is preferably operated
by a hydraulic cylinder L, the piston L of which is connected by links or
cables L L with arms projecting from the shaft or pivot of the hanger k³.
By this means the vertically swinging hanger 2 may be easily and quickly moved
out of the way and replaced in position. The shaft of the roll C may be adjusted
vertically up and down by means of a screw c.
The driven edging roll E and also the exterior pressure rolls G G are mounted upon
and carried by a horizontally moving slide M which travels in suitable guides M¹
on the main frame of the machine, and is actuated by a hydraulic cylinder N and its
piston Ni.
The sliding carriage M is furnished with cams or inclined grooves m m in which
fit pins or rollers o carried by the laterally vibrating levers 00 which serve to
automatically adjust the guide rolls D D. The guide rolls D D are carried by
laterally moving slides P P which travel in transverse guides P¹ P¹ on the main
frame of the machine. The guide rolls D D are mounted or journaled upon vertically
adjustable slides or blocks QQ which slide in suitable guides upon the transverse
slides P P. The motion of the levers O O is communicated to the guide rolls D D
by means of pivoted links O'O' which are furnished with screw threads and turn
buckles o¹ o' for purposes of adjustment.
As the exterior pressure rolls G G are carried by the same slide M, which through
its cams m actuate the guide rolls D D, the guide rolls D D will be automatically
and continuously kept in proper position, relative to the expanding diameter of the
tire, to maintain it of a true circular shape. By this means I am enabled to roll. the
tires or rings with great trueness and uniformity. The movable or edging pressure
roll F is made conical and its shaft F', upon which it loosely fits and revolves, is
mounted at an angle, preferably substantially as shown, in the vertical slide R so as
to compensate for the increased diameter of the tire at its outer edge and prevent
slipping and unnecessary friction. The vertical slide R reciprocates in suitable
guides R' on the horizontal slide M by which it is carried. The vertical slide or
carriage R is moved up and down or actuated by means of a hydraulic cylinder S on
the slide M and its piston S¹.
The rolls B and C may be made of any form desired according to the particular
kind of work designed to be done by the mill, the rolls being readily removable from
their shafts B', C. The particular rolls B, C which are shown in the drawings,
however, are of a novel construction, the same being designed for the purpose of
severing an annular ingot into distinct rings or tires.
To enable me to form the flanges of the tires out of the inside and best portion of
the ingot where the metal is of the most perfect character and free from imperfections,
I provide the roll B with annular grooves b adjacent to the cutter flange 6 so that
the flanges xx on the two contiguous tires will both be formed adjacent to the
line on which the annular ingot or ring is severed. The inside or movable roll C may
also be provided, if desired, with a cutter flange c¹ opposite the cutter flange b¹. The
rolls B, C are also furnished with bottom collars b, c.
The rolls B, C may also be furnished with cutter flanges or collars 63, c³, for the
purpose of severing a thin annular chip of imperfect metal from the top portion of
the annular casting at the same time that it is severed into two or more tires.
In the operation of the machine when the tire or bloom is being rolled outward or

page_text: to a larger diameter, I prefer to roll or force the tire outward against the constant
pressure of the exterior rolls G G and of the guide rolls D D, so that the expanding
tire or ring will itself automatically adjust the position of the rolls G G and D D, and
thus not only save the labor of the man or men heretofore usually employed for
adjusting these rolls, but also enable me to roll the tires or rings of a true circular
form. In this particular method or process of using the machine I ordinarily roll
the tire outward against the pressure exerted upon the rolls G G D D, or upon
their operating slide M, through the hydraulic cylinder N N₁, by the accumulator.
The pressure of the accumulator, as commonly employed in a tire rolling mill, is
ordinarily about 350 pounds to the square inch, and this I find to be a suitable degree
of pressure to use ordinarily. The degree of pressure on the rolls G G D D and
against which the tire is rolled outward, should, or may be, however, varied
materially according to weight and diameter or strength of the ring being rolled.
The required pressure upon the exterior rolls G G D D may be exerted by any
suitable means; for example in tire mills where the ordinary accumulator is not
employed the pressure may be communicated directly from one of the pumps to the
hydraulic cylinder N. I prefer to take the pressure from the accumulator as it
affords a steady and even pressure against which to roll the tire outward. In the
drawing the accumulator is indicated at T, and t is the pipe or connection between
the accumulator and the cylinder N. The construction of the accumulator is well
known to those skilled in the art and it therefore needs no special description. As
ordinarily constructed it consists simply of a large cylinder with a heavily weighted
piston or arm. When rolling the tire outward against the pressure of the accumulator
the valve controlling the communication between the accumulator and the cylinder N,
and which is indicated at t¹, is left open, so that the tire as it increases in diameter
must force the rolls G G, D D, to recede against the yielding pressure exerted upon
the piston N¹ of the cylinder N. The pressure exerted upon the exterior
rolls G G, D D, by the cylinder and piston N N is of course less than that
exerted upon the inside or pressure roll C when the tire is being rolled outward, as
otherwise the diameter of the tire would not increase.
It will be understood of course that my new or improved mill herein shown and
described may be used in the old method as well as in the new method just above
mentioned, or in other words that the position of the rolls G G and DD may be
from time to time adjusted by the operator. The vertical adjustment of the guide
rolls D D is effected by means of adjusting screws q q threaded into the vertically
movable blocks QQ. And the vertical adjustment of these guide rolls G G is effected
by means of adjusting screws 9 g.
By mounting the upper edging roll F loosely and so as to revolve on its non-
revolving shaft F¹, I obviate the difficulty heretofore experienced of the shaft F
getting out of line by reason of unequal wear in its two bearings owing to the pressure
of the hydraulic cylinder and piston S S' thereon.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
