STEPHEN P. M. TASKER, of the City and County of Philadelphia, and State of
Pennsylvania, United States of America. "IMPROVEMENTS IN CONTINUOUS ROLLING
MILLS."
Figure 1 of the Drawing is a central horizontal section, viewed from above, of so
much of my improved machine as is necessary to illustrate its practical construction,
section being supposed in the plane of the feed and between the rolls A, A².
Figure 2, a central longitudinal vertical sectional elevation of the same portion of
the machine, section being supposed in a vertical plane between the vertical rolls.
Figure 3, a cross section of one form of shaper or die.
Figure 4, cross sections of forms of sheets, plates, or bars produced by the use of
my machine.
Figure 5, a view of the apparatus as employed without shapers; and Figure 6,
sectional views of various forms of shapers.
My improvement relates to rolls for flat rolling, and more especially to that
subdivision of the same which both roll the flat surfaces and shape the edges of the
product acted upon.
Generally speaking my machine consists of a framework or housing, or of a series
of the same, supporting a single set or series of sets of horizontal and vertical rolls
placed alternately in pairs in a common line of feed, any roll, any pair, or all being
equipped with collars and shapers or collars, substantially as hereinafter set forth,
the rolls all being properly set and driven and provided with such adjustments and
devices as are usual in the employment and operation of similar rolla.
The object of my Invention is to produce flat sheets, bars, strips, or plates of
metal, the edges of which are shaped to any desired configuration, as for example
to such forms as are represented in Figure 4 in the Drawing.

page_text: In the Drawings I have represented so much of a construction of machine
embodying my Invention as is necessary to a comprehension of the said Invention,
and I have shown the vertical rolls only equipped with the shapers and collars.
In the Drawings A, A¹, represent a pair of plain-faced horizontal rolls mounted
in a suitable housing B.
C, C, a pair of vertical rolls also mounted in a suitable housing D. E, E³, are
two circular flanged collars fitted in the arrangement represented to the two vertical
rolls, and adapted to be secured at any desired point thereon by means of set
screws F, F', or similar devices.
These collars may be constructed of any desired form, that represented consisting
of a neck portion, to which the set screws are applied, and a flange or head e, et,
being a convenient form.
The opposing surfaces g, g¹, of the collars are flat and true with the opposing inner
surfaces h, h, of the guides, and are to be set in such manner as to be correspondent
with the said inner faces, whatever may be the size of the guides.
G, G¹, is a shaper, edge-die, or former fitted to likewise encircle the vertical rolls
and adapted to be held between the collars E, E', so as to become fixed in position
as indicated in Figure 2.
Each of the vertical rolls is similarly equipped with collars and shapers in
Figures 1 and 2.
In Figure 3 is represented in section the shaper G shown in Figure 2 in side
elevation.
The function of these shapers is the shaping of the edge of the sheet to a form
corresponding with that of the shapers, whatever the same may be.
H is a guide for conducting the metal to be rolled from and between the various
pairs of rolls.
As heretofore stated several sets of rolls may be used in series, in which arrange-
ment the guides are employed between each set.
The form of guide represented is funnel-shaped or bell-mouthed at its receiving
end, enclosed or box like, and of a construction and arrangement employed by me
for many years.
In the arrangement represented the collars do not touch, but a small space is left
between them into or near which the discharging end of the guide H projects. The
sides of tho guide are cut away to correspond with and merge into the periphery of
the collars E, E', while the top and bottom of the guides coincide, as described as to
their inside faces, with the opposing faces of the collars so as to form a continuous
enclosed pass or way.
When desired the collars can be made to touch together, and the guide shaped to
correspond. When rolls are arranged in series each succeeding guide is funnel
mouthed, and preferably arranged as represented in Figure 1.
The shapers may be of any form desired so as to form any given configuration
on the edge of the sheets or plate. In the operation of my machine the sheet
metal being first passed between the rolls A, A', is by them rolled out upon its flut
surfaces, caused to enter the guide H, and from thence caused to travel between the
vertical rolls, and to pass between the flanges of the collars E, E', which form a
continuation of the guide, so to speak, and in such manner is brought into contact
with the shapers G, and thereby fashioned upon its edges to a form corresponding
to that of the shapers employed. It is obvious that different forms of dies or
shapers may be employed, and that the form of the same may be predetermined to
the resultant shape desired. When it is sought to roll a plain square edge on one
side of the metal, the shaper on such side is dispensed with, and the metal shaped
upon its edge by the body of the vertical roll; and when desired the shapers may
be all dispensed with and the collars alone employed, the vertical rolls acting upon
the sides of the sheet to true such sides. The apparatus can of course be adjusted
to any desired thickness or dimension of plate by varying the adjustment of the
rolls, the size and interior dimension of the guides, the width and diameter of the
shapers, and the consequent distance apart and adjustment of the collars.

page_text: Instead of making both collars on each roll adjustable one may be fixed, and the
collars and shapers may be applied to the horizontal rolls as well as to the vertical.
The adjustability of the collars renders the rolls to which they are applied
susceptible of use with varying sizes of sheets, and effectuates the practical making
of an adjustable pass or rolling groove, while the employment of shapers still further
adds to their efficiency.
It will be understood that the shapers may be dispensed with at will, either as to
any given shaper or as to any given series of shapers acting upon a given side of
the sheet under process of rolling, or as to all and the rolls employed with the
adjustable collars only.
The guides may be made adjustable, or different sets may be employed.
Having thus described my Invention I claim and desire to secure,-
1. In combination with a pair of rolls adjustable collars E, E, substantially as
and for the purposes set forth.
2. In combination with a series of two or more sets of vertical and of horizontal
rolls adjustable collars E, E', substantially as and for the purposes set forth.
3. In combination with a pair of rolls C, C¹, shaper G, G³, as and for the purpose
set forth.
4. In combination with a series of two or more sets of vertical and of horizontal
rolls, arranged as described, shapers G, G', as and for the purposes set forth.
5. In combination with a pair of rolls C, C, adjustable collars E, E¹, and
shapers G, G, as and for the purposes set forth.
6. In combination with a series of sets of vertical and of horizontal rolls
arranged as described adjustable collars E, E², end shapers G, G', as and for the
purposes specified.
7. In combination with a series of two or more sets of vertical and of horizontal
rolls provided with collars E, E¹, guides H, coinciding to the pass formed by the
collars, substantially as set forth.
8. In combination with a series of two or more sets of vertical and horizontal
rolls provided with shapers and collars, as described, guides H coinciding to the
pass formed by the shapers and collars, substantially as described.
In witness whereof, I, the said Stephen P. M. Tasker, have hereunto set my
hand and seal, this Seventeenth day of May, A.D. 1879.
