IMPROVEMENTS IN MACHINERY FOR ROLLING TIRES
Year: 1884

page_text: I HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co Patent Agents,
Southampton Buildings in the County of Middlesex, do hereby declare the nature
of my invention for "IMPROVEMENTS IN MACHINERY FOR ROLLING TIRES" to bo
as follows:-
This invention relates to machines for rolling tires, and its object is to prevent
fins being formed upon the tire as it is rolled.
.
Heretofore tire-rolling machines have been provided with cutters or devices for
removing these fins from the bottom and top edges of the tire while the latter is
being rolled and as fast as they form thereon.
According to the present invention I slightly bevel. the collars of the rolls and
employ a pair of horizontal rolls to press against the edges of the tire so that no
fin whatever will be formed upon either edge of the tire, as, owing to the bevel
form of the said collars, the main rolls will merely form at each revolution or
passage of the tire between them slight ridges or projections on the edges of the
tire, which ridges or projections are instantly pressed back by the horizontal rolls
and the edges of the tire rendered straight and smooth before again passing between
the main rolls. In this way as no fins whatever are formed upon the tire, there is
neither any waste of metal nor any labor required in the removal of the said fins.
In carrying the said invention into practice I provide a suitable frame or bed
upon which are mounted a fixed roll, a movable or adjustable roll, and a horizontal
supporting roller upon which the tire rests and revolves. The fixed and movable
rolls are box rolls, that is to say are both provided with collars or flanges so that
there can be no tendency of any fins to form at the corners of the tire.
The inner edges of these collars or flanges have bevel surfaces which .inay extend
back the full depth of the collars, or the inner parts of the collars may be straight
while the outer portions only are bevelled.
As the tire passes between the rolls having these bevel collars or flanges, slight
ridges will be formed upon its edges, usually two ridges or projections with a
depression between them.

page_text: Above and below the main rolls are arranged horizontal rolls, which press against
the edges of the tire and serve to force or press the said ridges back, and to render
the edges of the tire straight and smooth.
The lower horizontal rolls are stationary and are journalled in suitable bearings
upon the frame of the machine, and assist also in supporting the tire. The upper
horizontal rolls are mounted on wings or pivotted segments, so that they may be
Bwung to and from the tire by means of the usual hand-wheel which engages with
the teeth. on the segments. The upper horizontal rolls are also adjustable vertically
by means of screws, the bearings or boxes of the said rolls being arranged to slide
vertically in their housings, in the ordinary manner. By means of the said screws,
which are provided with suitable hand-levers, the horizontal rolls may be set so as
to exert any desired degree of pressure upon the tire, or such as is necessary to
keep its edges straight and smooth.
Vertical rollers for guiding the tire are mounted on the segments in the usual
manner.
The degree of pressure required upon the horizontal rolls in order to obliterate
the ridges and keep the edges of the tire straight and smooth, is ordinarily not so
great as to make it necessary to drive them, but one or more of the lower
horizontal rolls may be driven, if preferred.
In this way the tire receives a much smoother and finer finish, upon its edges
than can be produced in the old way where fins are formed and have to be removed
either during the process of rolling or after it is completed.

page_text: 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 invention for ." IMPROVEMENTS IN, MACHINERY FOR ROLLING TIRES" and .in
what manner the sanie is to be performed, to be particularly described-and
ascertained in and by the following statement :-
This invention relates to machines for rolling tires, and its object is to prevent
fins being formed upon the tire as it is rolled.
Heretofore tire rolling machines have been provided with cutters or devices for
removing these fins from the bottom and top edges of the tire while the latter is.
being rolled and as fast as they form thereon.
ン
According to the present invention I slightly bevel the collars of the rolls and
employ a pair of horizontal rolls to press against the edges of the tire so that no fin
whatever will be formed upon either edge of the tire, as owing to the bevel form of
the said collars, the main rolls will merely form at each revolution or passage of the
tire between them slight ridges or projections on the edges of the tire, which ridges
or projections are instantly pressed back by the horizontal rolls and the edges of
the tire rendered straight and smooth before again passing between the main rolls.
In this way no fins whatever being formed upon the tire there is of course neither
any waste of metal nor any labor required in their removal.
In the accompanying drawing which forms a part of this specification,
Figure 1 is a plan view of a device embodying my invention.
Figure 2 is a side elevation of the horizontal rolls.
Figure 3 is a vertical section on line 3-3 of Fig. 1, and
Figure 4 is an enlarged cross-section of the tire, showing the form of the same
after leaving the main rolls and before reaching the horizontal or smoothing rolls;
the ridges or projections upon the edges of the tire being somewhat exaggerated for
the purpose of better illustrating the same.
In said drawing A represents the Trame or bed of a tire-rolling machine, or of
that portion of it to which my invention appertains-B is the outer or fixed roll,
B' the inner or movable roll, C the tire, and C¹₁ the horizontal supporting rollers
upon which the tire rests and revolves-The rolls B and B are box rolls, that is to
say are both provided with collars or flanges b, b and 61 61, so that there can be no
tendency of any fins to form at the corners of the tire-The inner edges of
these collars or flanges b, b¹ have bevel surfaces b 6ª, which bevel surfaces may
extend. back the full depth of the collars, or the inner part of the collar may be
straight while the outer portion only is beveled. As the tire C passes between the
rolls having these bevel collars or flanges slight ridges c will be formed upon its
edges, usually two ridges or projections with a depression c¹ between them—
D and D are the upper and lower horizontal rolls, which press against the edges of
the tire and serve to force or press these little ridges e back and to render the edges
of the tire straight and smooth. The lower rolls D' are stationary and are journaled
in suitable bearings upon the frame of the machine, and serve also to support the
tire the same as the rollers C¹. The upper rolls D are mounted on the wings or
pivoted segments H, so that they may be swung to and from the tire by means of the
usual hand-wheel hand worm h¹ which engages with the teeth of the segments.
The rolls D are also adjustable vertically by means of the screws d, the bearings or
boxes of said rolls being arranged to slide vertically in their housings H¹, in the
ordinary manner, By means of the screws d which are provided with suitablo

page_text: hand-levers, the rolls D D and D¹ D₁ may be set so as to exert any desired
degree of pressure upon the tire, or such as is necessary to keep its edges straight
and smooth. It will of course be understood by those skilled in the art, that here-
tofore in tire rolling machines, one or more upper rolls D D have been used to keep
the tire down upon its supporting rolls D¹ D¹, C'.
E' and E' are the vertical guide rollers mounted on the segments H, in the usual
way.
The degree of pressure required upon the horizontal rolls D and D¹, in order
to obliterate the ridges c, and keep the edges of the tire straight, and smooth, is
ordinarily not so great as to make it necessary to drive them, but one or more of
the under rolls D₁ may be driven if preferred."
In this way the tire is given a much smoother and finer finish upon its edges
than can be produced in the old way where fins are formed and have to be removed
either during the process of rolling or after it is completed.
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
I claim is
1. In a tire rolling machine, the combination of the rolls B B¹ having bevel
collars.or flanges with horizontal rolls D D¹ to straighten and smooth the edges
of the tire and prevent the formation of fins thereon as it is rolled, substantially as
specified.
2.―The rolls B B¹ provided with collars or flanges ¨b b and 6¹ 6ª having bevel
surfaces 6² 6³, substantially as specified.
